Background: Previous studies on arthroscopic treatment of anterior-inferior glenohumeral instability have focused on the repair of lesions of the anterior-inferior aspect of the labrum (Bankart lesions) and have demonstrated failure rates of as high as 50 percent. The current investigation supports the concept that anterior-inferior instability is associated with multiple lesions and that success rates can be increased by treating all of the lesions at the time of the operation. We present the results of arthroscopic treatment of anterior-inferior gleno-humeral instability after a minimum duration of followup of two years.Methods: The study group consisted of fifty-three patients who had a mean age of thirty-two years (range, fifteen to fifty-eight years) at the time of the operation. There were forty-four male and nine female patients. The mean interval from the time of the operation to the final follow-up evaluation was thirty-three months (range, twenty-six to sixty-three months). The scores on the American Shoulder and Elbow Surgeons (ASES) Shoulder Index and the rating systems of Constant and Murley, Rowe et al., and the University of California at Los Angeles (UCLA) were recorded preoperatively and at the time of the final follow-up.Results: Preoperatively, none of the patients had an overall rating of good or excellent according to the system of Rowe et al.; however, 92 percent (forty-nine) of the fifty-three patients had a rating of good or excellent at the time of the final follow-up. The mean score improved from 45.5 points to 91.7 points on the ASES Shoulder Index, from 56.4 points to 91.8 points with the system of Constant and Murley, from 11.3 points to 91.9 points with the system of Rowe et al., and from 17.6 points to 32.0 points according to the UCLA Shoulder Score (p = 0.001 for all comparisons). The mean passive external rotation with the shoulder in 90 degrees of abduction measured 88.2 degrees. Thirty-four of thirty-eight patients returned to their desired level of sports activity following the operation. Four patients who had persistent instability were considered to have had a failure of the index operation, and one of them had a second operative procedure.Conclusions: The results of the present study suggest that our technique of arthroscopic treatment of anterior-inferior glenohumeral instability is better than previous arthroscopic techniques and is equivalent to open repair. We believe that the improved rate of success demonstrated in the present study was the result of repair not only of the anterior-inferior (Bankart) lesion but also (where necessary) of inferior and superior labral tears. Additionally, soft-tissue tension within the capsule and ligaments was corrected with use of a suture technique but was supplemented by laser thermal capsulorrhaphy in forty-eight of the fifty-three shoulders. Rotator interval repair was considered a critical factor in fourteen of the fifty-three shoulders. [ABSTRACT FROM AUTHOR]

Background: The indications for resurfacing of the glenoid in patients who have osteoarthritis of the shoulder are not clearly defined; some investigators routinely perform hemiarthroplasty whereas others perform total shoulder arthroplasty. Methods: Forty-seven patients (fifty-one shoulders) who were scheduled to have a shoulder arthroplasty for the treatment of degenerative osteoarthritis were randomly assigned, according to a random-numbers table, to one of two groups: replacement of the humeral head with resurfacing of the glenoid with a polyethylene component with cement (total shoulder arthroplasty [twenty-seven shoulders]) or replacement of the humeral head without resurfacing of the glenoid (hemiarthroplasty [twenty-four shoulders]). All patients received the same type of humeral component, and all operations were performed by or under the direct supervision of the same surgeon. The patients were followed for a mean of thirty-five months (range, twenty-four to seventy-two months) postoperatively. Evaluation was performed with use of the scoring systems of the University of California at Los Angeles and the American Shoulder and Elbow Surgeons. Results: No difference was observed between the preoperative scores for the two groups of patients. Postoperatively, the mean scores with use of the University of California at Los Angeles system and the American Shoulder and Elbow Surgeons system were 23.2 points (range, 10 to 31 points) and 65.2 points (range, 15 to 94 points), respectively, after hemiarthroplasty and 27.4 points (range, 9 to 34 points) and 77.3 points (range, 3 to 100 points), respectively, after total shoulder arthroplasty. With the numbers available for study, no significant difference was found between the two operative groups with respect to the postoperative score. (Thirty-five subjects per group would be needed, assuming an effect size of 0.60 and a power of 0.80.) Total shoulder arthroplasty provided significantly greater pain relief (p = 0.002) and internal rotation (p = 0.003) than hemiarthroplasty did. Total shoulder arthroplasty also provided superior results in the specific areas of patient satisfaction, function, and strength, although none of these differences were found to be significant, with the numbers available. Total shoulder arthroplasty was associated with increased cost ($1177), operative time (thirty-five minutes), and blood loss (150 milliliters) per patient compared with hemiarthroplasty. To date, none of the total shoulder arthroplasties in the study group have been revised. Hemiarthroplasty yielded equivalent results for elevation and external rotation. Three of the twenty-five patients who had had a hemiarthroplasty needed a subsequent operation for resurfacing of the glenoid. The mean cost for the revision operations was $15,998. Conclusions: Total shoulder arthroplasty provided superior pain relief compared with hemiarthroplasty in patients who had glenohumeral osteoarthritis, but it was associated with an increased cost of $1177 per patient.

Purpose: The use of outcome measures (OMs) is a hallmark of contemporary physical therapy in the USA. The effect of OM utilization on patient care decisions and the results of PT services remain poorly understood. The purpose of this study is to explore PTs perceptions about the relationship between balance OMs and decision-making and how that interaction impacts patient outcomes, particularly for patients with acquired brain injury., Materials and Methods: This qualitative study used semi-structured phone interviews with an interview guide. Maximum variation sampling was used. Thematic analysis was situated in a priori determined theory-based categories., Results: Twenty-three physical therapists (PTs) from diverse geographic areas and practice settings participated. Therapists expressed diverse views on the impact of OM use on patient outcomes, but the majority perceived that using OMs improved rehabilitation outcomes. The use of OMs was related to the selection of optimal intervention type and intensity and justified continued high-frequency rehabilitation services. OMs were important to therapists' decision-making., Conclusions: In the present study, PTs reported that they believe the use of validated, clinically useful OMs may improve patient outcomes.Implications For RehabilitationBalance outcome measures are considered an important tool to the optimal management of the profound impact of balance impairments after brain injury.Most physical therapists in this study believe that using balance outcome measures results in better outcomes for patients with brain injury.In this study, physical therapists reported using outcome measures in wide-ranging ways to guide clinical decisions about balance in those with brain injury.

Background: The use of balance outcome measures (OM) is proposed to enhance physical therapy services and patient outcomes., Objective: Explore current practices of balance OM use and OM's role in United States physical therapists' decision-making with patient's acquired brain injury (ABI)., Methods: Cross-sectional survey utilizing snowball sampling, n = 373. Survey items required ranking agreement with statements on Likert scale. Multinomial logistic regression used to determine the relationship between survey answers and participant characteristics., Results: Ninety-three percent of therapists reported using outcome measures with patients with ABI. Those who reported not using outcome measures with patients with ABI were significantly different on setting, primary patient population, APTA section membership, and ANPT membership. All respondents who primarily treated neurologic diagnoses used outcome measure with clients with ABI, compared to 87% of respondents who worked primarily with orthopedic clients. Comfort, equipment availability, and psychometric properties were the most frequent reasons for choosing a measure. Therapist decision-making was impacted by outcome measures; this frequency was dependent on practice setting, primary patient population, and specialty certifications., Conclusions: Physical therapists use a low diversity of outcome measures to assess balance. Respondents rated psychometric properties as more important than past published research. This is the first study to demonstrate that outcome measures play a role for most United States PTs in decision-making in all stages of the patient management model including identification of problems, diagnosis, prognosis, intervention selection, termination of services, and discharge planning, as well justifying service delivery.

Study Design: Retrospective Diagnostic Cohort Study., Level of Evidence: Level 3b., Objectives: To examine the concurrent and predictive validity of a novel clinical assessment tool, the Functional Lumbar Index (FLI)., Background: Lumbar surgeries have increased exponentially in the past decade, adding to healthcare costs without improving outcomes. Limitations in clinicians' abilities to identify those individuals who are most likely to benefit from surgery may be enhanced with an effective physical assessment tool., Methods: The FLI was assessed on 291 individuals (179 conservative and 113 pre-surgical) seeking care for low-back pain (LBP) over a 2.5-year period. The FLI consists of several physical performance tests (PPT) with a novel criterion-based scoring system. Pearson correlations and Poisson regression analysis were used to establish concurrent and predictive validity at alpha = 0.05., Results: The subscale FLI components showed good to excellent inter-rater reliability with intraclass correlation coefficient values as follows: front plank = .993, right side plank = .824, left side plank .861, Sorensen = 0.836, overhead squat = 0.937. A statistically significant, moderate negative correlation was observed between FLI and modified Oswestry Disability Index (r = -0.540, p < .001). Regression analysis showed the FLI as the only significant predictor (p = .004) of failed conservative management for individuals with LBP. An ROC curve showed significant group prediction of the FLI with an AUC of 0.788 (p < .001) and cut-off score of 7.5., Conclusion: The FLI is a reliable and valid measure for predicting failed conservative care management in patients with LBP. Clinicians are encouraged to use the FLI as part of their physical assessment when screening individuals with LBP who might need surgical intervention. Further research is needed to determine validity of the FLI in other patient populations., Public Trial Registry: N/A., (Copyright © 2022 Elsevier Ltd. All rights reserved.)

Background and Purpose: A successful chair-rise is an important indicator of functional independence post-stroke. Lower extremity electromyographic analyses provide a basis for muscle activation from which clinical intervention protocols may be derived. Gluteus maximus activation during the chair-rise has not been thoroughly researched in the chronic stroke population. This study investigated the magnitude and onset of gluteus maximus activation during the chair-rise comparing adults post-stroke with healthy controls., Methods: In this cross-sectional study, adults with chronic stroke (n = 12) and healthy controls (n = 12) completed 4 natural-speed chair-rise trials. Magnitude and onset of bilateral gluteus maximus activation were measured during the movement with secondary comparative data from biceps femoris and vastus lateralis muscles. Kinetic and kinematic measurements were used to quantify chair-rise phases and movement cycle duration., Results: Significant decreases in paretic ( P = 0.002), and nonparetic ( P = 0.001) gluteus maximus magnitudes were noted post-stroke compared with ipsilateral extremities of healthy adults. Significant gluteus maximus onset delays were noted in paretic extremities compared with nonparetic extremities post-stroke ( P = 0.009) that were not apparent in comparative muscles. Similar onset times were noted when comparing the paretic extremity post-stroke to the ipsilateral extremity of healthy controls ( P = 0.714) despite prolonged movement cycle durations in those with chronic stroke ( P = 0.001). No onset delays were evident in the biceps femoris ( P = 0.72) or vastus lateralis ( P = 0.338) muscles., Discussion and Conclusions: Despite apparent unilateral muscle weakness post-stroke, bilateral decreases in gluteus maximus activation magnitudes and compounding onset deficits of the paretic extremity were observed during chair-rising. Further research is needed to determine whether interventions maximizing bilateral activation magnitudes and improving temporal activation congruency during chair-rising will carry over to functional gainsVideo Abstract available for more insights from the authors (see the Video, Supplemental Digital Content 1, available at: http://links.lww.com/JNPT/A387 )., Competing Interests: The authors declare no conflict of interest., (Copyright © 2022 Academy of Neurologic Physical Therapy, APTA.)

Background: We aimed to examine the effect of a high-intensity exercise bout on landing biomechanics in soccer players who underwent anterior cruciate ligament reconstruction (ACLR) and non-injured soccer players during a soccer-specific landing maneuver., Methods: Eighteen soccer players who underwent ACLR and 18 normal soccer players were enrolled in this investigation (ACLR group; age, 26.11 ± 3.95 years; body mass index, 23.52 ± 2.69 kg/m 2 ; surgery time, 5 ± 3.30 years: control group; age, 25.83 ± 3.51 years; body mass index, 24.09 ± 3.73 kg/m 2 , respectively). Participants were evaluated during the landing maneuver before and after carrying out the high-intensity exercise bout using the Wingate test. The intensity of the exercise was defined as a blood lactate accumulation of at least 4 mmol/L. The dependent variables included sagittal-plane kinematics and kinetics of the ankle, knee and hip joints, and electromyography activity of the gastrocnemius, hamstrings, quadriceps, and gluteus maximus., Results: On 2 × 2 analysis of variance, none of the dependent variable showed significant exercise×group interactions. Regardless of group, significant main effects of exercise were found. Post-exercise landing was characterized by increased flexion of hip (p = 0.01), knee (p = 0.001), and ankle joints (p = 0.002); increased extension moments of hip (p = 0.009), knee (p = 0.012), and ankle joints (p = 0.003), as well as decreased quadriceps activity (p = 0.007)., Conclusion: At 1 year or more post-ACLR, the effect of the high-intensity exercise bout on landing biomechanics is not expected to differ from that experienced by healthy soccer players.

The purpose of this study was to evaluate landing biomechanics in soccer players following ACLR during two landing tasks. Eighteen soccer players with an ACLR and 18 sex-matched healthy control soccer players participated in the study. Planned landing included jumping forward and landing on the force-plates, whereas unplanned landing included jumping forward to head a soccer ball and landing on the force-plates. A significant landing×group interaction was found only for knee flexion angles (p=0.002). Follow-up comparisons showed that the ACL group landed with greater knee flexion during planned landing compared with unplanned landing (p<0.001). Significant main effects of landing were found. The unplanned landing showed reduction in hip flexion (p<0.001), hip extension moments (p<0.013), knee extension moments (p<0.001), and peak pressure (p<0.001). A significant main effect for group for gastrocnemius muscle was found showing that the ACL group landed with reduced gastrocnemius activity (p=0.002). Unplanned landing showed greater injury predisposing factors compared with planned landing. The ACL group showed nearly similar landing biomechanics to the control group during both landing tasks. However, the ACL group used a protective landing strategy by reducing gastrocnemius activity., Competing Interests: The authors declare that they have no conflict of interest., (Thieme.

Objectives: Early physical therapy (PT) with specific stabilization training has been shown to benefit individuals after lumbar spinal surgery but has not been studied in patients after cervical spine surgery. The primary purpose of this study was to compare clinical outcomes between early cervical spine stabilizer (ECS) training and usual care (UC) in patients after anterior cervical discectomy and fusion (ACDF) surgery. The secondary purpose was to determine test-retest reliability of strength and endurance tests of cervical spinal stabilizers in this patient population., Methods: Forty participants who were scheduled for ACDF surgery were randomized into either the ECS group or the UC group. After surgery, participants received their assigned group intervention during their hospital stay and continued their assigned intervention for 12 weeks. All participants had phone follow-ups twice during the first 6 weeks to address questions or problems. Clinical outcome measures including pain level using the Numeric Pain Rating Scale (NPRS), disability level using the Neck Disability Index (NDI), Craniocervical Flexor Strength (CCF-S), and Craniocervical Flexor Endurance (CCF-E) were collected three times: before surgery and 6 and 12 weeks after surgery. Test-retest reliability was assessed in the first 10 participants., Results: There was no significant interaction between the groups over time for any of the outcome measures. However, all participants made significant improvements in all four outcome measures at 6 and 12 weeks post surgery. The results showed good-to-excellent test-retest reliability for the CCF-S and CCF-E tests., Conclusions: Both ECS training and UC resulted in the same amount of improvement at 6 and 12 weeks; therefore, both therapy approaches appear to have similar and positive effects on patients in their first 3 months of recovery after ACDF. Both the CCF-S and CCF-E tests can be used reliably to assess the strength and endurance of the cervical spinal stabilizers for patients after ACDF surgery. The study was registered with the ClinicalTrials.gov (NIH, U.S. National Library of Medicine, identifier # NCT01519115) Protocol Registration system., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2020 Carol McFarland et al.)

This randomized controlled trial examined the immediate effect of whole body vibration (WBV) on first position sauté height, and on static and dynamic balance, in 59 female professional contemporary dancers. Following instruction, a warm-up, and a training session, participants received a 75-second randomly assigned WBV intervention under four conditions: static demi-plié (0 Hz), static demi-plié (30 Hz), dynamic demi-plié (0 Hz), and dynamic demi-plié (30 Hz). Before and immediately after intervention, participants performed three sautés on the Just Jump ® Mat System, provided dynamic balance data via the Star Excursion Balance Test, and static balance data via the Balance Error Scoring System. A two-way split-plot multivariate approach ANOVA was used to analyze sauté height (α = 0.025). Balance was examined with a 4 x 2 x 2 split-plot MANOVA (α = 0.025). Follow-up two-way split plot multivariate approach ANOVAs were also conducted (α = 0.0125). Dancers from the static first position demi-plié group were found to jump higher than those from the dynamic first position demi-plié group, regardless of WBV frequency (p = 0.001). The 30 Hz frequency resulted in significantly improved static balance (p = 0.001) for both static and dynamic demi-plié. Therefore, the use of WBV is worthy of consideration as a quick method of improving static balance, and use of the static first position demi-plié may be beneficial for improving sauté height.

Background:: Prior studies have examined muscle power via the countermovement jump (CMJ). Studies to date have examined neither the reliability nor the construct validity of the ballet first position CMJ (hips in lateral rotation, toes facing away from one another, legs straight) as a measure of power., Hypotheses:: There would be (1) good interrater reliability in the visual assessment of the best-quality first position CMJ (κ ≥ 0.60), (2) good test-retest reliability in the height of the first position CMJ of good quality (intraclass correlation coefficient [ICC] ≥ 0.80), and (3) a significant relationship between isokinetic torque of the quadriceps femoris and first position CMJ height ( r ≥ 0.40)., Study Design:: Correlational study., Level of Evidence:: Level 3., Methods:: A convenience sample of 39 healthy young adults who reported moderate activity levels participated in a warm-up and 2 sessions of 6 jumps. Quadriceps femoris isokinetic torque was measured in the first session., Results:: Significant agreement was found within the same day for the best-quality first position CMJ (κ = 0.81), and in the highest, best-quality first position CMJ between days (ICC 2,1 = 0.88). The highest, best-quality first position CMJ, when solving for a single trial, was comparable to the average of 2 trials (single trial: ICC 2,1 = 0.96 vs average of 2 trials: ICC 2,k = 0.98). There was a good relationship between quadriceps femoris isokinetic strength and first position CMJ height (Pearson r = 0.69 and P < 0.001 at 60 deg/s; r = 0.64 and P < 0.001 at 180 deg/s; r = 0.65 and P < 0.001 at 300 deg/s)., Conclusion:: Visual video movement analysis has good to excellent interrater agreement and test-retest reliability. Selecting the single highest jump of good quality is acceptable. The first position CMJ is a measure of power., Clinical Relevance:: Video analysis of the single highest first position CMJ of good quality is an acceptable method of assessing movement quality.

Purpose: (1) Determine whether ultrasonography can detect differences in diaphragm contractility between body positions. (2) Perform reliability analysis of diaphragm thickness measurements in each test condition., Methods: We used a repeated-measures experimental design with 45 healthy adults where 3 B-mode ultrasound images were collected at peak-inspiration and end-expiration in supine, sitting, and standing. Mean diaphragm thickening fractions were calculated for each test position. Statistical significance was tested using 1-way repeated-measures analysis of variance with planned comparisons. For reliability analysis, the intraclass correlation coefficient (3, 3) was calculated., Results: Mean diaphragm thickening fraction increased from 60.2% (95% confidence interval [CI] 53.0%, 67.9%) in supine, to 96.5% (95% CI 83.2%, 109.9%) while seated and to 173.8% (95% CI 150.5%, 197.1%) while standing. Body position was a significant factor overall ( P < .001), as were comparisons between each individual position ( P < .001). Intraobserver reliability was excellent (>0.93) for all body positions tested., Conclusions: Ultrasound imaging detected positional differences in diaphragm contractility. The effect of gravitational loading on diaphragm length-tension, and body position-mediated changes in intra-abdominal pressure may explain the differences found. Future research should address methodological concerns and apply this method to patients participating in early mobilization programs in the intensive care unit., Competing Interests: The authors declare no conflicts of interest.

Study Design: Prospective cohort study of a cross-cultural low back pain (LBP) questionnaire OBJECTIVE.: The objectives of the present study were to translate and cross-culturally adapt the Fear-Avoidance Beliefs Questionnaire (FABQ) to create a version in Arabic and to test its psychometric properties., Summary of Background Data: The FABQ measures the effects that fear and avoidance beliefs have on work and on physical activity., Methods: An FABQ cross-culturally adapted for Arabic readers and speakers was created by forward translation, translation synthesis, and backward translation. Forty patients in Riyadh, Saudi Arabia, with LBP evaluated use of the questionnaire, and 70 patients from the same hospital participated in reliability, validity, and sensitivity studies. To determine test-retest reliability of the Arabic FABQ, patients completed it twice within 48 hours without receiving any active treatment between these two sessions. Patients completed the Arabic FABQ (and three other scales) at baseline and 14 days later to determine its validity and sensitivity., Results: Test-retest reliability was good (FABQ-work: intraclass coefficient [ICC] = 0.74; FABQ-physical activity: ICC = 0.90; FABQ overall: ICC = 0.76). Correlations between the FABQ and three other instruments for measuring pain and disability were weak. The strongest correlation was found at the follow-up session with the Arabic Oswestry Questionnaire (r = 0.283; P ≤ 0.05). Sensitivity to change was low., Conclusion: The translation and adaptation of the Arabic version of the FABQ was successful. Overall, the Arabic FABQ had good test-retest reliability, acceptable construct validity, and low sensitivity to change. The Arabic version of the FABQ shows promise in the assessment of fear-avoidance beliefs among patients with LBP who speak and read Arabic., Level of Evidence: 3.

Background/aims: Distal symmetrical peripheral neuropathy (DSPN) and sleep disturbances are among the most common complications reported in people living with the human immunodeficiency virus infection and acquired immunodeficiency syndrome (PLWHA). DSPN-pain is predominantly managed by using systemic agents with little evidence supporting their analgesic efficacy. The purpose of this study is to evaluate the effect of nighttime lower extremity splinting application on DSPN-related pain and sleep disturbances compared to a parallel splint liner application in PLWHA., Methods: Forty-six PLWHA and DSPN were randomized to nighttime wearing of bilateral lower extremity splints or the liners only. Pain and sleep outcomes were measured at baseline, week 3, and week 6. The pain was measured using the Neuropathic Pain Scale and sleep using the Pittsburgh Sleep Quality Index., Results: Pain and sleep scores improved in both groups over time. The median percentage pain reduction at week 6 was 8% in the liner group and 34% in the splint group. The change in pain scores in the splint group was found to be significant over time, P < .0005. The contrast between the splint and liner groups was underpowered (26%) and was not found to be significant, P > .05. Sleep scores improved 20% from baseline to the end of the study in both groups; all participants were classified as poor sleepers., Conclusion: The 6-week use of nighttime splints reduces DSPN-pain possibly by providing peripheral inhibition of external stimuli. Future studies are needed to validate this inhibitory intervention to manage DSPN in PLWHA and other neuropathic conditions., (© The Author(s) 2013.)

Background: Pain, sleep, and functional disturbances are a common occurrence in people living with HIV/AIDS-related distal sensory peripheral neuropathy (PLWHA-DSPN) yet lack group classification and quantification., Methods: A total of 46 PLWHA-DSPN were recruited, as part of a 2-group intervention study, to complete the Neuropathic Pain Scale and the Pittsburgh Sleep Quality Index (PSQI) questionnaires. The participant's performance during a forward reach task and walking distance in 6 minutes was recorded as a measure of function., Results: The pain (60.77 +/- 17.85) and sleep (14.62 +/- 4.28) scores denote marked pain and sleep disturbances, compared to seronegative, age-matched individuals. The ambulation distance was limited (243.99 +/- 141.04 m) and inversely associated with the PSQI-sleep efficiency subscale (rs = -.35, P < .05). The average reaching distances measured (36.07 +/- 7.37 cm) were similar to seronegative, age-matched individuals. Pain, sleep, and functional measures exhibited significant associations., Conclusions: The data collected suggest that PLWHA-DSPN report moderate-to-severe pain and significant sleep disturbances and exhibit limited ambulation distances.

Introduction: The pain associated with peripheral neuropathy (PN) observed in patients living with HIV/AIDS represents a difficult complication to manage., Participants: A total of 22 participants with a diagnosis of PN were recruited to assess the effects of using night splints on pain and sleep quality., Methods: For 3 weeks, the participants were instructed to use bilateral night splints and given an exercise regimen for 3 additional weeks. Scores from pain and sleep questionnaires were analyzed using repeated measures analysis of variance (ANOVA)., Results: The change in pain scores (F(1.16) = 13.41,η(2) =.456, P = .002) and sleep index scores (z = -2.69, P = .004, 1-tailed) was found to be significant following the use of night splints. No difference was found with the use of the exercises., Discussion: The use of night splints in HIV-infected patients with PN represents an additional tool for managing pain and improving sleep.

The comprehensiveness of physical therapists' adherence to the guidelines for red flag documentation for patients with low back pain has not previously been described. Therefore, the purpose of this study was to describe that comprehensiveness. Red flags are warning signs that suggest that physician referral may be warranted. Clinic charts for 160 patients with low back pain seen at 6 outpatient physical therapy clinics were retrospectively reviewed, noting the presence or absence of 11 red flag items. Seven of the 11 red flag items were documented over 98% of the time. Most charts (96.3%) had at least 64% of the red flag items documented. Documentation of red flags was comprehensive in some areas but lacking in others. Red flags that were regularly documented included age over 50, bladder dysfunction, history of cancer, immune suppression, night pain, history of trauma, saddle anesthesia, and lower extremity neurological deficit. The red flags not regularly documented included weight loss, recent infection, and fever/chills. Factors influencing item documentation comprehensiveness are discussed, and suggestions are provided to enhance the completeness of recording patient examination data. The study results provide a red flag documentation benchmark for clinicians working with patients with low back pain and they lay the groundwork for future research.

Objective: To evaluate 4 scales of shoulder function with respect to (1) their precision at different levels of shoulder function and (2) the measurement level of their raw scores (interval vs ordinal)., Design: Partial credit model calibration., Setting: Office of private practice orthopedic surgeon with practice limited to the shoulder., Participants: One-hundred ninety-two shoulder patients., Interventions: Participants completed the American Shoulder and Elbow Surgeons Patient Self-Evaluation Form (function subscale, modified), the disability subscale of the Shoulder Pain and Disability Index, the Simple Shoulder Test, and the function subscale of the University of Pennsylvania Shoulder Scale., Main Outcome Measures: The patients' responses were calibrated by using a partial credit model. We calculated standard errors of measurement and plotted the 95% confidence interval for different levels of shoulder functioning. We compared scales' raw scores with their equal interval measures obtained in the Rasch calibration., Results: The scales did not measure all levels of shoulder functioning with equal precision, suggesting that commonly used reliability estimates misrepresent scale precision in certain subpopulations., Conclusions: The scales' raw scores were found to be not of equal interval, calling into question the scoring systems recommended by the developers of these scales and the use of the scores in some statistical procedures., (Copyright 2001 by the American Congress of Rehabilitation Medicine and the American Academy of Physical Medicine and Rehabilitation)

This investigation presents the results of arthroscopic repair of bidirectional (inferior with either an anterior or a posterior component) glenohumeral instability in 54 patients with 2-year minimum follow-up. The study group consisted of 43 males and 11 females. The average age at the time of operation was 32 years (range, 15-55 years); the average interval from operation to final evaluation was 34 months (range, 26-63 months). The American Shoulder and Elbow Surgeons' Shoulder Index and the Constant, Rowe, and University of California at Los Angeles scores were recorded preoperatively and at final evaluation. Preoperatively, no patients rated good to excellent overall (according to the Rowe Scale), whereas at final follow-up 91% (49 of 54 patients) rated good to excellent. The American Shoulder and Elbow Surgeons' Shoulder Index improved to 94 from 45.5 (P =.001). The absolute Constant score improved to 92 from 57 (P =.001). The Rowe score improved to 92 from 20.3 (P =.001). The University of California at Los Angeles total score improved to 32.7 from 18.6 (P =.001). Average passive external rotation at 90 degrees of abduction measured 89.5 degrees. Forty patients returned to sports, but 10 (25%) of these patients participated at a lower level. For each of 4 patients, the index operation was considered a failure because of persistent instability; 1 patient underwent a second operative procedure. Thermal capsulorraphy (with a Holmium laser) of the glenohumeral ligaments was used to supplement suture repair, but in no shoulder was thermal capsulorraphy used as the only treatment. The etiology of bidirectional glenohumeral instability is complex, and operative correction of multiple intraarticular lesions was necessary.

Background and Purpose: Shoulder scales are often used to evaluate treatment efficacy, yet little is known about the psychometric properties of these scales. Only one scale has undergone psychometric scrutiny: the Shoulder Pain and Disability Index (SPADI). This study compared 2 shoulder measures-the University of California-Los Angeles (UCLA) Shoulder Scale and the Simple Shoulder Test (SST)-with the SPADI., Subjects: One hundred ninety-two patients with shoulder disorders were recruited from one physician's office to complete the self-report sections of the 3 scales., Methods: Cronbach alpha values and standard errors of measurement (SEM) were calculated for each of the multi-item subscales. Validity was examined through calculation of correlation coefficients among the 3 scales. Factor analysis was completed to assess the underlying constructs of the SPADI and the SST., Results: Cronbach alpha values ranged from.85 to.95. The SEM values for the multi-item scales ranged from 4.75 to 11.65. Evidence for validity to reflect function was indicated by the correlation between the SST and the SPADI disability subscale. The factor analysis of the SPADI revealed loading on 1 factor, whereas the SST loaded on 2 factors., Conclusion and Discussion: All scales demonstrated good internal consistency, suggesting that all items for each scale measure the same construct. However, the SEMs for all scales were high. Factor loading was inconsistent, suggesting that patients may not distinguish between pain and function.
