Background: Children with cerebral palsy (CP) or acquired brain insult (ABI) present with motor disorders affecting movement, muscle tone, and posture. While CP is commonly a consequence of perinatal brain insult (PBI), pediatric ABI can occur between birth and adolescence, with movement patterns that may not be consistent with CP., Research Question: Are gait patterns associated with CP different from those with pediatric ABI?, Materials/methods: Children with unilateral motor impairment and history of ABI at ≥18 months of age were identified from gait lab records and matched with children with CP having a history of PBI at ≤ 1 year old. Matching was by GMFM-D, age at Instrumented Gait Analysis (IGA), and sex. Kinematic and temporospatial data from the earliest IGA were analyzed. The primary outcome measurement was average knee flexion in stance, as children with CP tend to walk with a more flexed knee and individuals with a brain insult as older children, youth and adults tend to walk with a more extended knee. Secondary variables were temporospatial parameters and lower limb kinematics in stance and swing. Wilcoxon or T-Tests were used., Results: Twenty-six unilaterally affected children with CP (age: 10.8±3.3 years; f:6/m:20; GMFCS I:14, II:38), and 26 unilateral children with ABI (age:11.1±4.3 years; f:6/m:20) were included in each group. Significantly lower knee flexion angles during stance and swing, and shorter single support duration on the affected side were found in the ABI group as compared to CP (p<0.05). In children with ABI, there was a negative correlation between age of insult and severity of internal hip rotation (p<0.05)., Conclusions/significance: Children with ABI tend to walk with less stability on the affected side as reflected by the more extended knee and reduced single support compared with children with CP. The age at which the brain insult occurs has a significant effect on the hip rotational profile in children with ABI. Further studies on muscle activation patterns, kinetic data and response to treatment are warranted to gain insight on how the stage of brain and musculoskeletal system development at the time of injury affect gait patterns., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Jose Salazar-Torres reports a relationship with Colliers Project Leaders that includes: consulting or advisory.

Background: The Shriners Hospital Upper Extremity Evaluation (SHUEE) is a video-based measure designed to assess upper extremity function in people with cerebral palsy (CP). The SHUEE completes both dynamic positional analysis (DPA; position during functional activities) and spontaneous functional analysis (spontaneous use of the involved limb). Although the SHUEE has been suggested as a measure for planning upper limb interventions and evaluating outcomes, limited evidence of its ability to detect change exists. Thus, this study aimed to describe responsiveness of the SHUEE to detect change after orthopaedic surgery., Methods: In this Institutional Review Board-approved retrospective cohort study, we identified children with CP who were administered SHUEE on≥2 encounters. We formed pairs of initial and follow-up visits between temporally adjacent visits. Pairs were assigned to a surgery or non-surgery group based on intervening upper limb orthopaedic surgery. We compared differences in baseline SHUEE scores between groups and differences in temporally adjacent SHUEE scores within groups using Welch unequal variances t tests and paired t tests, respectively., Results: Nineteen people (7 female) with hemiplegic CP had≥2 SHUEE assessments; Manual Ability Classification System levels I (3), II (8), III (7), IV (1); Gross Motor Function Classification System levels I (10), II (7), IV (2); mean age at baseline 11.9 (5.1 to 19.1) years; and follow-up at 13.4 (5.5 to 19.7) years. Six people had≥2 visits leading to 14 surgical pairs and 10 non-surgical pairs. At baseline, DPA of the wrist and forearm were significantly lower in the surgical group ( P <0.05). At follow-up, no significant difference between the groups existed in DPA measures ( P >0.05). After surgical intervention, there was a significant change in overall and wrist DPA ( P <0.05)., Conclusions: The DPA measures demonstrated responsiveness to expected positional changes in the arm after orthopaedic surgery in people with CP. The SHUEE was useful in identifying abnormal segmental alignment pre-surgically and documenting changes in alignment postoperatively. As orthopaedic surgery does not address limb neglect or bimanual ability, spontaneous functional analysis scores were as expected-unchanged., Level of Evidence: Level III, retrospective cohort study., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2023 Wolters Kluwer Health, Inc.

Background: Children with cerebral palsy (CP) at Gross Motor Function Classification System (GMFCS) levels III/IV are at risk for losses in standing function during adolescence and transition to adulthood. Multilevel surgery (MLS) is an effective treatment to improve gait, but its effects on standing function are not well documented. The objectives of our study were to describe standing function in children with CP classified as GMFCS levels III/IV and evaluate change after MLS., Methods: This retrospective study included children with CP (GMFCS III/IV) ages 6 to 20 years who underwent instrumented gait analysis. A subset who underwent MLS were evaluated for change. Primary outcome measures were Gross Motor Function Measure dimension D, gait velocity, functional mobility scale, and the Pediatric Outcomes Data Collection Instrument (PODCI). Additional impairment level measures included foot pressure, knee extension during stance phase of gait, and knee extension passive range of motion., Results: Four hundred thirty-seven instrumented gait analysis sessions from 321 children with CP (ages 13.7±4.8 y; GMFCS III-81%/IV-19%) were included. The GMFCS III group had higher Gross Motor Function Measure dimension D, gait velocity, PODCI scores, and better knee extension compared with the GMFCS IV group ( P <0.05); 94 MLS were evaluated for postoperative change 15.3±4.2 months after MLS. Children at GMFCS level III had improved PODCI scores ( P <0.05), better knee extension passive range of motion ( P <0.01), and improved coronal plane foot pressure ( P <0.05) post MLS. Maximum knee extension during stance and heel impulse improved significantly in both groups ( P <0.01)., Conclusions: Standing function of children with CP at GMFCS IV was significantly more limited than at GMFCS III. After MLS, both groups (III/IV) showed improvement in impairment level outcomes (knee extension and foot position), whereas only those functioning at GMFCS III had improvement in activity/participation outcomes according to the PODCI. For children with CP at GMFCS levels IV, MLS may improve standing function, but appropriate goals related to assisted standing and measurement protocols sensitive to limited functional mobility should be adopted., Level of Evidence: Level III-retrospective comparative study., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

Benefits of hamstring lengthening surgery on the sagittal plane in children with cerebral palsy have been previously demonstrated, but there is limited information on its effects on the transverse plane. This study compared the effects of medial hamstring lengthening (MHL) with those of medial and lateral hamstring lengthening (MLHL) procedures in the transverse plane. Children with gross motor function classification system (GMFCS) levels I-III who had MHL or MLHL were included. Baseline, short- (1-2 years), and long-term (3+ years) postoperative three-dimensional gait analysis outcomes were compared using analysis of variance. Children were excluded if they had concurrent osteotomies or tendon transfers. One hundred fifty children (235 limbs) were included, with 110 limbs in the MHL group (age 8.5 ± 4.1 years, GMFCS I-27%, II-52%, and III-21%) and 125 limbs in the MLHL group (age 10.0 ± 4.0 years, GMFCS I-23%, II-41%, and III-37%). Time between surgery and short- and long-term follow-up gait analysis was 1.5 ± 0.6 years and 6.6 ± 2.9 years, respectively. Transmalleolar axis became more external after MHL at both short and long terms ( P < 0.05), whereas there were only significant differences at long term in MLHL ( P < 0.05). Although hamstring lengthening has a positive impact on stance phase knee extension in children with cerebral palsy, intact lateral hamstrings after MHL likely contribute to increased tibial external rotation after surgery. Significant increases in external rotation at the knee in the long term are likely related to a trend present with growth in children with cerebral palsy rather than a direct result of surgical intervention., (Copyright © 2022 Wolters Kluwer Health, Inc.

Background: Previous studies have looked at the short-term effectiveness of conservative and surgical treatment of children with cerebral palsy (CP), but few have explored the long-term outcomes into adulthood using gait analysis and patient-reported outcome measures., Research Question: How do gait, mobility, and patient-reported outcomes in adults with CP who received specialized pediatric orthopedic care change from adolescence?, Methods: We identified 645 adults with 1) CP, 2) age 25-45 years, and 3) an adolescent instrumented gait analysis (IGA) at our center. Measurement outcomes included physical examination, IGA, and select domains of the Patient-Reported Outcomes Measurement Information System (PROMIS)., Results: Participants included 136 adults with CP; Gross Motor Function Classification System levels I (21 %), II (51 %), III (22 %), and IV (7%); 57 % males; and average age 16 ± 3/29 ± 3 years (adolescent/adult visits). There was no significant difference in gait deviation index, stride length, or gross motor function between adolescent and adult visits. There were statistically significant but not clinically meaningful declines in gait velocity. At adulthood, PROMIS results revealed limitations in physical function compared with a normative sample but no differences in depression, participation, or pain interference., Significance: In this relatively homogeneous group of adults with CP who received orthopedic care from one center, gait and gross motor function showed no clinically meaningful change from adolescence, which differs from recent reports of declining mobility in adulthood. Expert orthopedic care, guided by IGA, may prevent losses in functional mobility for adults with CP., (Copyright © 2021 Elsevier B.V. All rights reserved.)

Background: Children with cerebral palsy (CP) often present with a stiff knee gait pattern because of rectus femoris (RF) spasticity and/or contracture. Rectus femoris transfers (RFTs) and resections are surgical procedures aimed at reducing muscle stiffness, thereby improving knee flexion during the swing phase of gait. Previous research has consistently demonstrated objective benefits of rectus transfer using instrumented gait analysis (IGA). Rectus femoris resection (RFR), a relatively simpler procedure, shows similar improvement in knee range of motion during gait. The objective of this study was to compare surgical outcomes between rectus transfers and resections using 3-dimensional IGA., Methods: Children with spastic CP who had RFTs or resections were retrospectively matched by walking speed and preoperative knee kinematics from 3-dimensional IGA (peak and timing of peak knee flexion in swing). Secondary outcomes included knee range of motion and maximum knee extension during gait., Results: Twenty-eight children were included in both the transfer group [age 9.4±2 y; Gross Motor Function Classification System (GMFCS) I (3 children), II (15 children), III (8 children), and IV (2 children)] and the resection group [age 10.6±2.5 y; GMFCS I (1 child), II (14 children), and III (13 children)]. Both surgical groups showed statistically significant short-term postsurgical improvements in peak knee flexion during swing (P<0.001 for the transfer group and P=0.003 for the resection group) and Duncan-Ely test (P=0.004 for the transfer group and P<0.001 for the resection group). Further analysis by GMFCS level showed children at GMFCS levels III/IV had a greater tendency to crouch after RFT when compared with children at GMFCS levels I/II. This tendency was not observed in the RFR group., Conclusions: Both transfer and resection surgeries significantly improved gait kinematics short-term outcomes in children with spastic CP who present with stiff knee gait pattern. Further studies are required to compare long-term outcomes of both surgeries., Level of Evidence: Level III-retrospective matched-cohort study., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2021 Wolters Kluwer Health, Inc.

While passive range of motion (PROM) is commonly used to inform decisions on therapeutic management, knowledge of PROM of children with spastic cerebral palsy (CP) is limited. A population-based sample of 178 children with spastic CP (110 male; unilateral, n = 94; bilateral, n = 84; age range 4-17 years) and 68 typically developing children (24 male; age range 4-17 years) were recruited to the study. All children were able to walk a minimum of 10 m over a straight flat course, with or without assistive devices. Gross Motor Function Classification System (GMFCS) levels of participants with CP were: Level I = 55, Level II = 88, Level III = 21, and Level IV = 14. Ankle dorsiflexion, knee extension, popliteal angle, hip abduction, hip internal rotation, and hip external rotation were measured using a goniometer. The results indicate that the children with CP had significantly reduced PROM compared to the children with typical development. Children with CP demonstrated reduced length in the hamstrings, hip adductor, iliopsoas and gastrocnemius-soleus musculature, and contracture at the knee joint. Among children with CP, there were significant reductions in range with increasing functional limitation (higher GMFCS level) and variations based on unilateral or bilateral involvement. This was particularly the case for the hamstrings and hip adductor musculature, where PROM varied considerably across GMFCS Levels I to IV.

Caregivers of children with cerebral palsy (CP) experience stress surrounding orthopaedic surgery related to their child's pain and recovery needs. Social determinants of health can affect the severity of this stress and hinder health care delivery. A preoperative biopsychosocial assessment (BPSA) can identify risk factors and assist in alleviating psychosocial risk. This study examined the relationship between the completion of a BPSA, hospital length of stay (LOS), and 30-day readmission rates for children with CP who underwent hip reconstruction (HR) or posterior spinal fusion (PSF). Outcomes were compared with a matched group who did not have a preoperative BPSA. The BPSA involved meeting with a social worker to discuss support systems, financial needs, transportation, equipment, housing, and other services. A total of 92 children (28 HR pairs, 18 PSF pairs) were identified. Wilcoxon analysis was statistically significant (p = 0.000228) for shorter LOS in children who underwent PSF with preoperative BPSA (median = 7.0 days) vs. without (median = 12.5 days). Multivariate analysis showed that a BPSA, a lower Gross Motor Function Classification System level, and fewer comorbidities were associated with a shorter LOS after both PSF and HR (p < 0.05). Identifying and addressing the psychosocial needs of patients and caregivers prior to surgery can lead to more timely discharge postoperatively. [ABSTRACT FROM AUTHOR]

Introduction: The transition from pediatric health care and school systems presents enormous challenges for young adults with cerebral palsy (CP). The lack of strong societal support during this seminal life event is well-documented and leads many adults with CP to struggle with independence, higher education, and employment. Despite the relatively high prevalence of CP, information about the experiences and function of adults with CP in our society continues to be limited. The purpose of this project was to describe well-being by assessing education, employment, physical function, walking activity, and utilization of health care in an ambulatory adult cohort with CP who received specialized pediatric care at our center. Method: In this Institutional Review Board-approved prospective study, we invited former patients from our tertiary care pediatric CP center to complete a set of patient-reported outcomes including (1) the Patient-Reported Outcomes Measurement Information System domains of physical function and pain interference, (2) the Satisfaction with Life Scale, and a project-specific demographic questionnaire about education, employment, income, independence, pain, and health care utilization. Participants also wore a pedometer for 8 days to monitor community walking activity. Chi-squared pairwise or t -tests were used as appropriate to compare survey responses and walking activity data between three groups: participants who self-reported, those who reported by proxy, and published normative data from age-matched typically developing adult (TDA) samples. Results: One hundred twenty-six adults with CP consented to participate; 85 self-reported [age 29.7 ± 4.3 years; Gross Motor Function Classification System: I (28%), II (47%), and III, (25%)] and 41 reported by proxy [age 29.7 ± 4.1 years; Gross Motor Function Classification System: I (10%), II (68%), and III (22%)]. For the group who self-reported, high school graduation rate (99%) was similar to TDA (92%; p = 0.0173) but bachelor's degree achievement rate (55%) was higher than TDA (37%; p < 0.001). Despite more advanced education, the unemployment rate in this group was higher than national levels at 33% and was associated with high utilization of Social Security Disability Insurance (33%). Within the self-reporting group, 13% required a caregiver. For the group who reported by proxy, educational levels (73% high school graduates, 0 bachelor's degree) were lower than the general population (p < 0.001) and unemployment was higher than the national level, at 64%. Unemployment in this group was associated with high utilization of Social Security Disability Insurance (85%). Within the proxy-reporting group, 71% required a caregiver. The full cohort demonstrated lower levels of physical function according to the Patient-Reported Outcomes Measurement Information System and less community walking activity compared with TDA references (p < 0.001). This cohort of adults with CP reported significantly higher frequency of chronic pain (48 vs. 12% for TDA; p < 0.001), but less pain interference with daily activities than TDA based on Patient-Reported Outcomes Measurement Information System results (p < 0.001). This cohort reported good to excellent overall health (93%) and high utilization of primary care (98%), but limited utilization of specialty care, specifically orthopedic care (21%) and physical therapy (15%). Discussion: This cohort of adults with CP had similar levels of education as the general population, but had relatively high rates of unemployment, caretaker need, and Social Security Disability Insurance utilization. Although chronic pain was frequent, the impact of pain on work and independent living did not exceed reports from a typically developing reference. Better targeted societal resources for adults with physical disabilities are urgently needed to allow equitable access to employment, promote opportunities for independence, and enable full participation in community life.
