This article discusses a clinical trial, NCT06598644, that compares the effectiveness of two therapeutic techniques, Cervical Sustained Natural Apophyseal Glide (SNAG) and Instrument-Assisted Soft Tissue Mobilization (IASTM), in treating mechanical neck pain. The trial aims to determine which method is more effective in reducing pain, improving range of motion, and enhancing overall neck function in individuals suffering from mechanical neck pain. Mechanical neck pain is a common condition characterized by pain that worsens with specific neck movements or sustained postures. Cervical SNAGs involve sustained glides to the cervical spine to address joint dysfunction, while IASTM uses specialized tools to improve tissue quality. Both techniques have potential benefits in reducing pain and improving neck function. The study is not yet recruiting participants, and the target enrollment is 56 individuals. The eligibility criteria include individuals between the ages of 20 and 45 with a history of neck pain. The study will take place in Pakistan, and the primary investigator is Kinza Anwar.

• Innovative method using a single camera and posture mirror measures trunk rotation angles. • High reliability and validity demonstrated, avoiding the need for expensive equipment. • Bland-Altman analysis confirms absence of systematic errors in measurements. This study aimed to measure trunk rotation angle representations from images using a single camera combined with a posture mirror and to examine its reliability and validity. We applied a trunk rotation angle model using a tripod and markers simulating trunk rotation. We compared two methods of trunk rotation angle measurement: the conventional method from the superior aspect using a manual goniometer and a novel measurement method using images from a digital camera and a posture mirror. Measurement error was calculated as the average absolute error between the angle measured by the goniometer and that calculated from the camera and mirror image. The intraclass correlation coefficient (ICC 1, 1) and ICC (2, 1) were calculated as the intra-rater reliability and agreement between the measurement angles of the two methods, respectively. Systematic errors of the angles measured by the two methods were examined by a Bland‒Altman analysis. The mean (SD) of the mean absolute error was 1.17° (0.71°). ICC (1, 1) was 0.978, and ICC (2, 1) was 0.991. The Bland‒Altman analysis showed no systematic errors. The results suggest the validity and accuracy of our novel method to measure the angle of trunk rotation, which does not require high-cost equipment or a special environment.

• Wearable full wireless goniometer was designed for upper and lower limb. • The designed system has activity recognition. • The designed system can measure in real-time and show joints' movements in a 3D model simultaneously. • The system achieves high accuracy range of motion measurements. People must move using their lower and upper extremities to complete their work. Depending on these extremities' using frequency or different effects such as age, genetics, and body weight, the extremities' ability may decrease. The joints' range of motion(ROM) is measured to evaluate this decrease. Different systems, such as conventional goniometers, mobile phone applications, and sensor-based systems, can measure the ROM value. Still, it can be challenging to measure this parameter in different situations, such as training, moving activities, etc. The partial wireless goniometer and a companion 3D visualization and control GUI were developed in our previous study. However, it was difficult to mount it on the limbs at a distance, or it was impossible to use it for both legs to measure the hip angles. Therefore, this study presents a full wireless goniometer system that can simultaneously measure in real-time and show joint movements in a 3D model for the upper and lower extremities. The angle values required for the ROM were measured with two IMU sensors. Two ESP32s were used as microcontrollers in the system, and a fully wireless system was enabled by transferring data via ESP-NOW and Bluetooth. Thanks to ESP-NOW, the system has less latency compared to other protocols and can transmit data over longer distances. The developed system can also perform activity recognition which is not available in other goniometers. The measurements of the system were compared with a conventional goniometer, and their results were found to be completely correlated (ρ c = 1). [Display omitted] [ABSTRACT FROM AUTHOR] more...

Introduction: To date, only few studies have been performed on the accuracy of manual angle manipulation during orthopedic surgery. This cadaver study was aimed at quantitatively assessing the accuracy of manual angle manipulation performed by orthopedic surgeons according to their surgical experience and comparing it with manipulation performed with the assistance of a digital goniometer. Materials and methods: Six lower-leg specimens of fresh-frozen human cadavers were subjected to angle manipulation performed via Kirschner wire (K-wire) insertion. K-wires were inserted manually and with the assistance of a digital goniometer at target angles of 0°, 30°, and 60° by three operators who had different levels of experience in orthopedic surgery. The accuracy of the insertion angles at the target angles was evaluated using computed tomography. Results: The mean angle error in the manual angle manipulation was 8.8° (standard deviation [SD] 6.0). When the target angles were set to 0°, 30°, and 60°, the identified angle errors were 6.1° (SD 4.3), 8.8° (SD 6.6), and 11.7° (SD 5.6), respectively, and each value did not show any significant difference among the operators. With the assistance of a digital goniometer, the mean (SD) angle error was significantly improved to 2.1° (1.1°) (p < 0.001). The amount of improvement in accuracy significantly increased as the target angle increased (p = 0.01). Conclusion: This cadaver study quantified the inaccuracy of manual angle manipulation in orthopedic surgery and showed that these inaccuracies can be improved using an assistive device. These results support the need to develop a device that can compensate manual angle manipulation in orthopedic surgery. [ABSTRACT FROM AUTHOR] more...

CHILDREN with cerebral palsy , *GONIOMETERS , *OSTEOTOMY , *ELECTROMAGNETIC measurements - Abstract
Femoral derotation osteotomy (FDO) is a well‐established procedure for the correction of internal rotation gait in children with cerebral palsy. Various studies have demonstrated good results for FDO both in short‐term and long‐term evaluation with some describing recurrence and over‐ or under‐corrections. The present study evaluates the use of an objective intraoperative derotation measurement through electromagnetic tracking. We report the static and dynamic results of 11 cases with internal rotation gait (8 male, 3 female, mean age 22.2 years), that underwent FDO with intraoperative electromagnetic tracking and conventional goniometric measurement of the correction. The dynamic and static changes were assessed through three‐dimensional gait analysis after a mean of 12 months after surgery and rotational imaging preoperative and after a mean of eleven days postoperatively. Mean hip rotation in stance significantly decreased from 20.9° (SD 5.9) to 5.8° (SD 4.7°) after FDO. The mean amount of derotation quantified by electromagnetic tracking was 23.2° (16.5°–28.8°) and 25.1° (20.0°–33.0°) for goniometric measurement. Both measurement modalities showed small differences to rotational imaging (electromagnetic bone tracking [EMT]: 0.72°; goniometer: 1.19°) but a large deviation when compared to three‐dimensional gait analysis (EMT: 8.5°, goniometer: 9.1°). In comparison to the static changes and EMT measurement, the dynamic changes measured during 3‐D‐gait analysis reflected only 66% of the actual derotation performed during surgery. Although electromagnetic tracking allows a precise intraoperative assessment of the derotation during FDO, the amount of intraoperative correction is not reflected in the improvements in three‐dimensional gait analysis.

Introduction: The hip joint is subjected to daily stresses as it bears the weight of the upper body. Osteoarthritis of the hip may cause irreversible damage. Proximal geometry of the femur, like neck-shaft angle and torsion is important in designing prostheses for a specific population. Most of the prostheses manufacturers follow the Western parameters as there is a scarcity of data in the Indian context. Aim: To analyse the normal Neck-Shaft Angle (NSA) and torsion of the femur in the Indian population. Materials and Methods: This cross-sectional analytical study was carried out in a total of 300 dried femur (150 right and 150 left) of unknown age and gender without any defect or damage during a period of 2.6 years (June 2019 to December 2021) in Sumandeep Vidyapeeth University, Gujarat, India. The NSA and the angle of femoral torsion was measured using a Goniometer. Mean and standard deviation were calculated. Student's t-tests was applied to ascertain the statistical difference between right and left femur. Results: The average NSA was 128.55±6.99°. The mean values were 130.70±6.03° and 126.41±7.22° on right and left sides respectively with statistically significant difference (p-value <0.0001). The average femoral torsion was found to be 16.43±2.34°. On the left side, it was 16.43±2.31° and 16.43±2.36° on the right side with No statistically significant difference was found between right and left femorae (p-value=1.00). Conclusion: The accuracy and success of the hip replacement surgery demands complete knowledge of the morphometry of the proximal femur which is highly specific among the races, region and gender. The present study provides the normal morphometry of the proximal femur of Indian population. [ABSTRACT FROM AUTHOR] more...

Background: Stiffness, or more precisely, a restriction in the range of motion, is a potential complication following any intra- or extra-articular injury. The passive or active range of motion of the physiological joint is an important factor in determining the significance of joint stiffness. The goals of this study were to assess the incidence of joint stiffness following a fracture, using a standard goniometer, and to identify potential predictors of joint stiffness among post-fracture patients. Methods: A prospective hospital-based cross-sectional study was conducted from July 1, 2021 to September 13, 2021, at University of Gondar Comprehensive Specialized Hospital. A total of 230 study participants participated in the study, and systematic sampling methods were used to recruit the study participants. Bivariate and multivariable binary logistic regression model analyses were conducted, with SPSS version 23, to identify factors associated with post-fracture joint stiffness. Results: The overall prevalence of post-fracture stiffness was 25.7% (n=59). Having a left-side fracture (AOR=10.83; 95% CI 1.71– 17.74), patients having no physiotherapy follow-up (AOR=6.72; 95% CI 1.79– 25.13), and patients using assistive devices (AOR=11.95; 95% CI 3.63– 39.35) were significantly associated with post-fracture stiffness, with p-values of less than 0.05. Conclusion: The study found that one-quarter of the study participants experienced post-fracture joint stiffness. A fracture on the left side, individuals with no physiotherapy follow-up, and the use of assistive devices were found to be independent predictors of joint stiffness. Early referral of fracture patients to the rehabilitation center is recommended to prevent post-fracture complications and joint stiffness. [ABSTRACT FROM AUTHOR] more...

The separator is a porous membrane and is the most important part of a lithium-ion battery. One viable alternative material used as the membrane is polypropylene (PP). This membrane has the advantages of being available in various sizes, well-controlled porosity, thermally and chemically stable, as well as low cost. Therefore, this study aims to determine the characteristics of the polypropylene membrane including the wettability value using a contact angle goniometer, surface morphology using SEM (Scanning Electron Microscopy), thermal properties using a thermogravimetric analyzer and thickness using a digital screw micrometer. The study was firstly conducted by preparing a PP membrane and the characteristics were then tested. The results showed that the contact angle was <90° indicating that the wetting value is good because of the fact that various membrane surfaces are wetted. The SEM test then indicated a homogeneous pore-shaped morphology. Furthermore, the differential scanning calorimetry (DSC) and the thermogravimetric analysis (TGA) tests showed that the PP membrane is capable of withstanding high temperatures up to 139°C, while the thickness test showed a value <25 m.

In recent years, verification and validation processes of automated driving systems have been increasingly moved to virtual simulation, as this allows for rapid prototyping and the use of a multitude of testing scenarios compared to on-road testing. However, in order to support future approval procedures for automated driving functions with virtual simulations, the models used for this purpose must be sufficiently accurate to be able to test the driving functions implemented in the complete vehicle model. In recent years, the modelling of environment sensor technology has gained particular interest, since it can be used to validate the object detection and fusion algorithms in Model-in-the-Loop testing. In this paper, a practical process is developed to enable a systematic evaluation for perception–sensor models on a low-level data basis. The validation framework includes, first, the execution of test drive runs on a closed highway; secondly, the re-simulation of these test drives in a precise digital twin; and thirdly, the comparison of measured and simulated perception sensor output with statistical metrics. To demonstrate the practical feasibility, a commercial radar-sensor model (the ray-tracing based RSI radar model from IPG) was validated using a real radar sensor (ARS-308 radar sensor from Continental). The simulation was set up in the simulation environment IPG CarMaker® 8.1.1, and the evaluation was then performed using the software package Mathworks MATLAB®. Real and virtual sensor output data on a low-level data basis were used, which thus enables the benchmark. We developed metrics for the evaluation, and these were quantified using statistical analysis. [ABSTRACT FROM AUTHOR] more...

Background: Subjects with frozen shoulder (FS) might not be comfortable with vigorous physical therapy. Clinical trials assessing the effect of graded motor imagery (GMI) in FS are lacking. The aim of this study was to determine the effect of GMI as an adjunct to conventional physiotherapy in individuals with painful FS. Methods: Twenty subjects aged 40--65 years having stage I and II of FS were randomly divided into two study groups. The conventional physiotherapy group (n = 10) received electrotherapy and exercises while the GMI group (n = 10) received GMI along with the conventional physiotherapy thrice a week for 3 weeks. Pre- (Session 1) and post- (Session 9) intervention analysis for flexion, abduction, and external rotation range of motion (ROM) using a universal goniometer, fear of movement using the fear avoidance belief questionnaire (FABQ), pain with the visual analogue scale, and functional disability using the shoulder pain and disability index (SPADI) was done by a blinded assessor. Results: Statistically significant difference was seen within both the groups for all the outcomes. In terms of increasing abduction ROM as well as reducing fear of movement, pain, and functional disability, the GMI group was significantly better than control group. However, both groups were equally effective for improving flexion and external rotation ROM. Conclusions: Addition of GMI to the conventional physiotherapy proved to be superior to conventional physiotherapy alone in terms of reducing pain, kinesiophobia, and improving shoulder function for stage I and II of FS.

Background: Stabilizing exercises reduce pain intensity, improves shoulder position and scapular function, and provides an appropriate strategy for the improvement of scapular dyskinesia. The purpose of this study was to investigate the effect of six weeks of stability exercises (stretching-strengthening) on joint proprioception, strength, and range of motion of the glenohumeral joint in female tennis players with scapular dyskinesia. Methods: Thirty-six female elite tennis players with scapular dyskinesia in both experimental and control groups participated in this study. Goniometer, Isokinetic and Biodex devices were used to evaluate the range of motion, internal and external rotation strength in 60° and 180°, and joint proprioception at 45° and 60°, respectively. Also, the lateral scapular slide test (LSST) was used to evaluate the scapulohumeral rhythm. For analyzing dependent variables and determining statistical significance the ANCOVA and an alpha of 5% was used. Results: The results of this study indicated the effect of the stability exercise program on the range of motion of internal (p = 0.016) and external (p = 0.023) rotation of the shoulder. Also, significant differences were observed between the control and training groups for internal rotation strength 60° (p = 0.013), 180° (p = 0.017) and external rotation strength 60° (p = 0.005), 180° (p = 0.045) and strength ratio 60° (p = 0.001) and 180° (p = 0.023). However, there were no significant differences for proprioception. Conclusion: In general, the findings of this study support the effectiveness of exercise therapy as a safe intervention for improving scapular function in tennis players with scapular dyskinesia.

A goniometer is currently the gold standard for range of motion (ROM) measurements. However, trained staff are required for accurate measurements. The objective of this study is to assess an agreement between the proposed standalone inertial measurement unit glove, smartphone device, and a standard goniometer for the measurement of wrist range of motion. Twenty participants performed wrist flexion, wrist extension, pronation, supination, ulnar deviation, and radial deviation movements with three operators measuring the movements with three devices. Average measurements from the three approaches had within 1.5 degrees of difference from each other for all of the movements. Both the proposed IMU glove and smartphone showed a strong correlation to the goniometer in most of the movements, with an intraclass correlation coefficient (ICC) between 0.914 and 0.961, and between 0.929 and 0.951, respectively. Only wrist supination using the smartphone has an ICC of 0.828. In comparison with a standard goniometer, a smartphone device is a more convenient method and readily available. The proposed IMU glove requires additional hardware but is easier to use and is more suitable for measuring and monitoring dynamic motion than a smartphone or a goniometer. These patient-friendly approaches could be used by the patients at home and provide remote quantitative monitoring during the wrist rehabilitation process. [ABSTRACT FROM AUTHOR] more...

This study examined the test re-test, intrarater and interrater reliability of joint kinematics from the Coach's Eye smartphone application. Twenty-two males completed a 1-repetition maximum (1-RM) assessment followed by 2 identical sessions using 5 incremental loads (20, 40, 60, 80, 90% 1-RM). Peak flexion angles at the hip, knee, and ankle joints were assessed using 1 experienced practitioner and 1 inexperienced practitioner. The acceptable reliability thresholds were defined as intraclass correlation coefficient (ICC) r > 0.70 and coefficient of variation CV = 10%. The test re-test reliability of peak hip and knee flexion were reliable across 20-90% 1-RM (r > 0.64; CV < 4.2%), whereas peak ankle flexion was not reliable at any loaded condition (r > 0.70; CV < 20.4%). No significant differences were detected between trials (p > 0.11). The intrarater reliability was near perfect (r > 0.90) except for peak ankle flexion (r > 0.85). The interrater reliability was nearly perfect (r > 0.91) except for hip flexion at 80% 1-RM and ankle flexion at 20% (r > 0.77). Concludingly, the Coach's Eye application can produce repeatable assessments of joint kinematics using either a single examiner or 2 examiners, regardless of experience level. The Coach's Eye can accurately monitor squat depth. [ABSTRACT FROM AUTHOR] more...

Ankle is the most common site of hardware removal, mainly performed within 12 months of the primary surgery. The prominence of the metallic hardware is a frequent cause of pain after fracture fixation. Over the last decade, the development of bioresorbable materials based on magnesium (Mg) has increased. Bioresorbable metals aim to avoid a second surgery for hardware removal.
Methods: Twenty patients with isolated, bimalleolar, or trimalleolar ankle fractures were treated with bioresorbable screws made of Mg, 0.45wt% calcium (Ca) and 0.45wt% zinc (Zn) (ZX00). Patient-reported outcome measures (PROMs) including visual analogue scale (VAS) for pain, the presence of complications 6 and 12 months after surgery and the AOFAS scale after 12 months were reported. The functional outcomes were analysed through the range of motion (ROM) of the ankle joint with a standard goniometer. Degradation products and the bioresorbability of the screws were evaluated using plane radiographs.Results: One patient was lost to follow-up. All patients were free of pain, no complications, shoe conflict or misalignement were reported after 12 months of follow-up. No Mg screws were surgically removed. An additional fixation of the distal fibula or the dorsal tibial fragment with conventional titanium implants (Ti) was performed in 17 patients. Within 12 months after primary refixation, 12 of these patients (71%) underwent a second surgery for Ti hardware removal. The mean AOFAS score was 89.8±7.1 and the difference between the treated and the non-treated site in the ROM of the talocrural joint was 2°±11° after 12 months. Radiolucent areas around the screws were attributed to degradation and did not affect clinical or functional outcomes. After one year, the Mg screw heads could not be detected in the plane radiographs of 17 patients which suggests that the majority of the screw head is degraded without introducing adverse reactions.Conclusions: At 6 and 12 months, the bioresorbable Mg screws show excellent PROMs without complications or need for screw removal. The resorbability of the screw heads in most of the patients after one year could also provide an advantage over conventional bio-inert implants by avoiding related skin irritation due for instance to shoe conflict.

The conductive slip ring is used for power or signal transmission between two objects rotating relative to each other. It has become an essential part of modern industrial development. In traditional automated production measurements, the typical method is to use calipers, goniometers, or angle gauges to measure a parameter of the workpiece several times and then average it. These inspection means have low measurement accuracy and slow measurement speed, and measurement data cannot be processed in a timely manner. A machine vision-based method for measuring and controlling the angle of the brushes is proposed for this problem. First, the brush angle forming device was built for the conductive slip ring brush wire, forming the principle and rebound characteristics. Then, machine vision and image processing algorithms were applied to measure the key parts of the conductive slip ring brushes. The data of the forming angle value and rebound angle value were obtained during the forming process of the brush wire angle. Finally, a pre-compensation model for the brush filament rebound was developed and validated based on the curve fitting method. The test results show that the error of the angle measurement is within 0.05°. The average error of the measured rebound angle and the calculated rebound angle of the brush filament pre-compensation model was 0.112°, which verifies the correctness of the pre-compensation model. The forming angle can be controlled more precisely, and the contact performance between the brush wire and the ring body can be improved effectively. This method has the potential to be extended to engineering applications. [ABSTRACT FROM AUTHOR] more...

WETTING ,COMPUTER simulation ,HYSTERESIS ,GONIOMETERS ,DROPLETS - Abstract
Dynamic wetting phenomena are typically described by a constitutive law relating the dynamic contact angle θ to contact-line velocity U
CL . The so-called Davis–Hocking model is noteworthy for its simplicity and relates θ to UCL through a contact-line mobility parameter M, which has historically been used as a fitting parameter for the particular solid–liquid–gas system. The recent experimental discovery of Xia & Steen (2018) has led to the first direct measurement of M for inertial-capillary motions. This opens up exciting possibilities for anticipating rapid wetting and dewetting behaviors, as M is believed to be a material parameter that can be measured in one context and successfully applied in another. Here, we investigate the extent to which M is a material parameter through a combined experimental and numerical study of binary sessile drop coalescence. Experiments are performed using water droplets on multiple surfaces with varying wetting properties (static contact angle and hysteresis) and compared with numerical simulations that employ the Davis–Hocking condition with the mobility M a fixed parameter, as measured by the cyclically dynamic contact angle goniometer, i.e. no fitting parameter. Side-view coalescence dynamics and time traces of the projected swept areas are used as metrics to compare experiments with numerical simulation. Our results show that the Davis–Hocking model with measured mobility parameter captures the essential coalescence dynamics and outperforms the widely used Kistler dynamic contact angle model in many cases. These observations provide insights in that the mobility is indeed a material parameter. [ABSTRACT FROM AUTHOR] more...- Published

Modelling of material appearance from reflectance measurements has become increasingly prevalent due to the development of novel methodologies in Computer Graphics. In the last few years, some advances have been made in measuring the light-material interactions, by employing goniometers/reflectometers under specific laboratory's constraints. A wide range of applications benefit from data-driven appearance modelling techniques and material databases to create photorealistic scenarios and physically based simulations. However, important limitations arise from the current material scanning process, mostly related to the high diversity of existing materials in the real-world, the tedious process for material scanning and the spectral characterisation behaviour. Consequently, new approaches are required both for the automatic material acquisition process and for the generation of measured material databases. In this study, a novel approach for material appearance acquisition using hyperspectral data is proposed. A dense 3D point cloud filled with spectral data was generated from the images obtained by an unmanned aerial vehicle (UAV) equipped with an RGB camera and a hyperspectral sensor. The observed hyperspectral signatures were used to recognise natural and artificial materials in the 3D point cloud according to spectral similarity. Then, a parametrisation of Bidirectional Reflectance Distribution Function (BRDF) was carried out by sampling the BRDF space for each material. Consequently, each material is characterised by multiple samples with different incoming and outgoing angles. Finally, an analysis of BRDF sample completeness is performed considering four sunlight positions and 16x16 resolution for each material. The results demonstrated the capability of the used technology and the effectiveness of our method to be used in applications such as spectral rendering and real-word material acquisition and classification. [Display omitted] • A robust pipeline to acquire BRDF samples of real-world materials. • UAV-RGB and hyperspectral sensors are used to observe material-light interactions. • An efficient methodology to capture measured reflectance data in outdoor scenarios. • The coverage of the BRDF space and an estimation for further flights are presented.

Chronic obstructive pulmonary disease (COPD) is the third leading cause of death worldwide with over 3 × 106 deaths in 2019. Such an alarming figure becomes frightening when combined with the number of lost lives resulting from COVID-caused respiratory failure. Because COPD exacerbations identified early can commonly be treated at home, early symptom detections may enable a major reduction of COPD patient readmission and associated healthcare costs; this is particularly important during pandemics such as COVID-19 in which healthcare facilities are overwhelmed. The standard adjuncts used to assess lung function (e.g., spirometry, plethysmography, and CT scan) are expensive, time consuming, and cannot be used in remote patient monitoring of an acute exacerbation. In this paper, a wearable multi-modal system for breathing analysis is presented, which can be used in quantifying various airflow obstructions. The wearable multi-modal electroacoustic system employs a body area sensor network with each sensor-node having a multi-modal sensing capability, such as a digital stethoscope, electrocardiogram monitor, thermometer, and goniometer. The signal-to-noise ratio (SNR) of the resulting acoustic spectrum is used as a measure of breathing intensity. The results are shown from data collected from over 35 healthy subjects and 3 COPD subjects, demonstrating a positive correlation of SNR values to the health-scale score.

While native SAD phasing is a promising method for next‐generation macromolecular crystallography, it requires the collection of high‐quality diffraction data using long‐wavelength X‐rays. The crystal itself and the noncrystalline medium around the crystal can cause background noise during long‐wavelength X‐ray data collection, hampering native SAD phasing. Optimizing the crystal size and shape or removing noncrystalline sample portions have thus been considered to be effective means of improving the data quality. A crystal‐processing machine that uses a deep‐UV laser has been developed. The machine utilizes the pulsed UV laser soft ablation (PULSA) technique, which generates less heat than methods using infrared or visible lasers. Since protein crystals are sensitive to heat damage, PULSA is an appropriate method to process them. Integration of a high‐speed Galvano scanner and a high‐precision goniometer enables protein crystals to be shaped precisely and efficiently. Application of this crystal‐processing machine to a long‐wavelength X‐ray diffraction experiment significantly improved the diffraction data quality and thereby increased the success rate in experimental phasing using anomalous diffraction from atoms.

In recent years, different types of commercial rollators or gait-training devices have been widely used by elderly people, suffering from dementia, for their daily activities to avoid being bedridden. However, the effectiveness of most of these commercial devices has not been investigated thoroughly. In this study, a novel rollator with a freely rotating chest pad, integrated with two angular sensors and two load cells, was developed. Walk measurements were carried out on four young healthy subjects who performed walk tests using the developed rollator. To measure the motion of the lower limbs, two goniometers were attached to the exteriors of both the knees, and two more were attached to the exteriors of both the ankle joints of the subjects. The results of the pressing forces on the pad measured by the load cells, pad rotations, knee extensions, and ankle rotations were demonstrated. Frequency analyses were performed and correlation coefficients were computed for the obtained results. The relationship between the pad rotation and the motion of the lower limbs was investigated, and the effectiveness of the developed novel rollator in walk assistance was discussed.

Cervical spondylosis has gradually become a high-incidence disease in today’s society. The cervical range of motion (CROM) is widely used as the evaluation criterion of cervical status, whereas the existing methods of CROM measuring are not humanized enough. Consequently, the purpose of this study was to develop a novel photogrammetric method to assess three-dimensional CROM. Three smartphone cameras were controlled to simultaneously capture three-direction photographs of the subject wearing the special designed device with three mark lines. The obtained photographs were uploaded to a PC and the mark lines in each photograph were extracted by utilizing both the Radon transform and the Hough transform. By calculating and combining the tilt angles of three mark lines, the CROM of the subject was indirectly determined. The performance of our method was compared with the goniometer-based method: the inter-instrument reliability was excellent for all six cervical movements with intraclass correlation coefficients $>$ 0.99; the degree of agreement between the two methods was high with Pearson’s coefficients $>$ 0.98; and the Bland-Altman plots also revealed the validity of our method. Moreover, the concept of a cervical motion curve was put forward to describe the movement track of the neck in order to reflect the cervical health status. The proposed approach is feasible, automatic and convenient for the measurement of CROM and the generated cervical motion curve can intuitively exhibit the trajectory of the neck. This technique that can easily acquire the biomedical information of the cervical spine has tremendous potential in the diagnosis, healthcare and wellness management of the neck.

This study aimed to examine the reliability and validity of using a smartphone to measure the multi-joint range of motion of the lower limbs. We measured the straight leg raise angle, ankle dorsiflexion angle, and hip internal rotation angle in each of the 40 lower extremities of 20 healthy adults. Measurements were compared between a conventional method using a goniometer and a smartphone application method. The intraclass correlation coefficient (ICC) was used to evaluate the reliability of each smartphone measurement, and Bland-Altman analysis was used to examine measurement errors. The criterion-related validity of the two methods was also examined. Intra-rater reliability (ICC 0.668-0.939) was substantial to almost perfect, with no systematic errors found for all items, and the standard errors of measurement were acceptable. Inter-rater reliability (ICC 0.701-0.936) was also substantial to almost perfect, but the straight leg raise angle and hip internal rotation angle showed fixation errors. For these two measurements, with more than one examiner, the limit of agreement of error needs to be considered. No systematic errors were found in the ankle dorsiflexion angle, and the standard error of measurement was within the acceptable range. A moderate to strong correlation (r = 0.626-0.915) was found between the conventional and smartphone methods, demonstrating good criterion-related validity. However, in the ankle dorsiflexion angle measurements, the reliability and validity were shown to be lower than the other two items. This suggested the necessity of changing the measurement conditions in order to use the ankle dorsiflexion angle in clinical practice. [ABSTRACT FROM AUTHOR] more...

In spite of the increasing number of balance assessment studies, the relationship between painful upper extremity and balance disorders is not yet fully understood. The objective of this paper was to determine if balance was affected by painful should er syndromes. A total of 40 adults aged between 20-60, 20 with painful shoulder syndrome (study group) and 20 with healthy shoulders (control group). Stability tests and the risk of fall were evaluated with the help of a Biodex Balance device, the range of motion was evaluated with the help of a universal goniometer, and the intensity of pain was measured with the help of vis ual analog scale (VAS) in both groups. While the overall stability index, one of the subgroups of the stability test, differed between the groups (p< 0.05), no difference was observed in the fall risk scores (p=0.05). Stability test scores showed a positiv e significant correlation with the pain intensity, according to the VAS: pain during night (r2=0.452, p=0.045) and pain while doing any activity (r2=0.764, p=0.000). Individuals with painful shoulders may have a stability disorder. In addition to classical measurement methods in individuals with shoulder pain, emphasis should be placed on balance assessment and shoulder evaluations may be required in adults with atypic al balance disorders.

We developed a smartphone application to measure wrist motion using the mobile device's built-in motion sensors or connecting it via Bluetooth to a wearable sensor. Measurement of wrist motion with this method was assessed in 33 participants on two occasions and compared with those obtained with a standard goniometer. The test–retest reproducibility in healthy individuals ranged from good to excellent (intraclass correlation (ICC) 0.76–0.95) for all motions, both with and without the wearable sensor. These results improved to excellent (ICC 0.90–0.96) on the second test day, suggesting a learning effect. The day-to-day reproducibility was overall better with the wearable sensor (mean ICC 0.87) compared with the application without using sensor or goniometer (mean ICC 0.82 and 0.60, respectively). This study suggests that smartphone-based measurements of wrist range of motion are feasible and highly accurate, making it a powerful tool for outcome studies after wrist surgery.

Background: Range of motion after total knee arthroplasty (TKA) can impact patients' daily lives. Nevertheless, flexion contracture (FC) often recurs after TKA, even upon achieving full extension intraoperatively. This study aimed to evaluate the relationship among preoperative, intraoperative, and postoperative knee extension angles, and clarify the risk factor for postoperative FC. Methods: One hundred forty-seven knees undergoing TKA using a navigation system were evaluated. We measured the pre- and postoperative (6 months after TKA) extension angles using a goniometer, and intraoperative (before and after TKA) extension angle using a navigation system; the correlation between these angles at each time point was evaluated. Results: The mean preoperative, intraoperative (before and after TKA) and postoperative extension angles were -9.9°, -6.8°, -0.1°, and -2.0°. Regarding intraoperative extension angle after TKA, 58 knees showed ≤ 5° hyperextension and six knees showed > 5° hyperextension. At 6 months, no cases showed hyperextension and 105 knees showed full extension. The mean intraoperative extension angle after TKA in the postoperative full extension group was 0.4°. A significant correlation was found among extension angles at each point (p<0.01, respectively). However, the intraoperative extension angle after TKA correlated with the postoperative extension angle only in females. Contrarily, the recurrence rate of FC was significantly higher in males than in females (p<0.01). Conclusion: Intraoperative extension angles significantly correlated with pre- and postoperative extension angles in TKA. Moreover, intraoperative mild (≤ 5°) hyperextension is acceptable for postoperative full extension. There was a gender-specific difference in correlation between intra- and postoperative knee extension angles. Level of evidence: III. [ABSTRACT FROM AUTHOR] more...

Introduction: The incidence of postoperative hyperextension and factors affecting hyperextension needs to be investigated separately for cruciate retaining (CR) and posterior stabilized (PS) total knee arthroplasties (TKAs), because the mechanism for preventing hyperextension is different according to the bearing design. The purpose of the study was to compare the incidence of postoperative hyperextension between CR and PS TKAs and analyze the factors affecting the postoperative hyperextension. Methods: Matched 213 CR and PS TKAs with Persona® prosthesis were retrospectively reviewed. The preoperative demographics, clinical and radiographic knee condition, and pelvic incidence were similar between groups. Appropriate knee extension (0°–5°), confirmed with a goniometer, was achieved intraoperatively. The knee sagittal angle was radiographically measured preoperatively and at 2 years postoperative. The incidence of hyperextension (sagittal angle < − 5°) was investigated. The factors affecting the postoperative hyperextension were analyzed in terms of age, sex, preoperative mechanical axis, knee sagittal angle, postoperative posterior tibial slope (PTS), change of posterior femoral offset, and pelvic incidence. Results: The knee sagittal angle was not significantly different preoperatively between CR and PS TKAs. The postoperative knee sagittal angle was 2.9° in CR TKAs and 4.4° in PS TKAs (p = 0.004). The incidence of postoperative hyperextension was 11.7% (25/213) in CR TKAs and 4.2% (9/213) in PS TKAs (p = 0.007). The preoperative sagittal angle, postoperative PTS, and pelvic incidence were the significant factors affecting the postoperative hyperextension in CR TKAs (odds ratio 0.869, 2.205, and 1.045, respectively); the preoperative sagittal angle was only the significant factor in PS TKAs (odds ratio 0.857) Conclusions: Postoperative knee hyperextension occurred more frequently and was affected by more factors in CR TKAs than PS TKAs. Efforts to avoid hyperextension and closed observation are required in TKAs performed in patients with the risk factors. Level of evidence: III. [ABSTRACT FROM AUTHOR] more...

Background: The Oslo Sports Trauma Research Center (OSTRC) Shoulder Injury Prevention Program is an exercise program developed to increase the internal rotation (IR) range of motion (ROM), external rotator muscle strength and scapular muscle strength and to improve kinetic chain involvement and thoracic mobility. The purpose of this study is to investigate the effect of this program on glenohumeral ROM and upper extremity functional performance in adolescent throwers. Material and methods: Ten adolescent throwers (discus, shot put and javelin throwers) were involved in the study. The OSTRC Shoulder Injury Prevention Program was applied three times a week for 8 weeks as a part of warm-up. Glenohumeral IR and external rotation (ER) ROM were evaluated with a goniometer. The Closed Kinetic Chain Upper Extremity Stability Test (CKCUEST) was used to evaluate the upper extremity functional performance. Results: It was found that there was a statistically significant difference in the dominant side IR ROM and CKCUEST between the pre-test and post-test (p<0.05); however, there was no difference in terms of other parameters (p>0.05). Conclusions: This study shows that the glenohumeral IR ROM and upper extremity functional performance increases after the 8-week OSTRC Shoulder Injury Prevention Program. For these purposes, physiotherapists and trainers can include this program in their training programs. [ABSTRACT FROM AUTHOR] more...
