Comparability between wearable inertial sensors and an electronic walkway for spatiotemporal and relative phase data in young children aged 6-11 years. Gait Posture 2024; 111:30-36. [PMID: 38615566 DOI: 10.1016/j.gaitpost.2024.04.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/04/2023] [Revised: 03/26/2024] [Accepted: 04/04/2024] [Indexed: 04/16/2024]
Abstract
BACKGROUND Approaches to gait analysis are evolving rapidly and now include a wide range of options: from e-patches to video platforms to wearable inertial measurement unit systems. Newer options for gait analysis are generally more inclusive for the assessment of children, more cost effective and easier to administer. However, there is limited data on the comparability of newer systems with more established traditional approaches in young children. RESEARCH QUESTION To determine comparability between the Physilog®5 wearable inertial sensor and GAITRite® electronic walkway for spatiotemporal (stride length, time and velocity, cadence) and relative phase (double support time, stance, swing, loading, foot flat and push off) data in young children. METHODS A total 34 typically developing participants (41% female) aged 6-11 years old median age 8.99 years old (interquartile range 2.83) were assessed walking at self-selected speed over the GAITRite® electronic walkway while concurrently wearing shoe-attached Physilog®5 IMU sensors. Level of agreement was analysed by Lin's concordance correlation coefficient (CCC), Bland-Altman plots and 95% limit of agreement. Systematic bias was assessed using 95% confidence interval of the mean difference. RESULTS Excellent to almost perfect agreement was observed between systems for spatiotemporal metrics: cadence (CCC=0.996), stride length (CCC=0.993), stride time (CCC=0.996), stride velocity (CCC=0.988). The relative phase metrics adjusted for stride velocity showed improved comparability when compared to the unadjusted metrics: swing adjusted (adj) (CCC=0.635); stance adj (CCC: 0.879); loading adj: (CCC=0.626). SIGNIFICANCE Spatiotemporal metrics are highly compatible across GAITRite® electronic walkway and Physilog®5 IMU systems in young children. Relative phase metrics were somewhat compatible between systems when adjusted for stride velocity.

Distal femoral osteotomy and patellar tendon advancement for the treatment of crouch gait in patients with bilateral spastic cerebral palsy. Gait Posture 2024; 110:53-58.

Abstract
BACKGROUND Crouch gait, or flexed knee gait, represents a common gait pattern in patients with spastic bilateral cerebral palsy (CP). Distal femoral extension and/or shortening osteotomy (DFEO/DFSO) and patellar tendon advancement (PTA) can be considered as viable options when knee flexion contractures are involved. Better outcomes have been reported after a combination of both, independently of the presence of knee extensor lag. In this study, we evaluated the clinical and kinematic outcomes of these procedures. PATIENTS AND METHODS We reviewed a cohort of 52 limbs (28 patients) who were treated for crouch gait by DFEO/DFSO alone (group 1, n = 15) or DFEO/DFSO + PTA (group 2, n = 37) as a part of single event multilevel surgery (SEMLS). The mean age at surgery was 14 years, and the mean follow-up time was 18 months. The physical examination data and three-dimensional standardized gait analysis were collected and analyzed before the surgery and postoperatively. RESULTS Overall knee range of motion improved in all limbs. The knee flexion decreased significantly in both groups at initial, mid, and terminal stance. Hip flexion significantly decreased in mid-stance for limbs in group 2. Both clinical and gait parameters were most improved in limbs who underwent DFEO/DFSO + PTA. Increased pelvic tilt was observed in both groups after surgery. CONCLUSION Although DFEO/DFSO alone was successful in correcting knee flexion contractures, PTA has helped to improve knee extensor lag and knee extension during gait. LEVEL OF EVIDENCE Therapeutic level IV.

Abstract
BACKGROUND This study aimed to evaluate gait outcomes and strength following the surgical correction of equinus in cerebral palsy (CP) based on different surgical procedures. We included the Baumann and Strayer procedures, as well as the Achilles tendon lengthening (ATL). METHODS A retrospective analysis was performed in patients with infantile, bilateral CP who received instrumental 3D gait analysis before and after surgical correction (18.66 months postoperatively). Patients were divided into 3 groups: Strayer surgery, Baumann surgery, and ATL. Gait performance and muscle strengths were compared between studied surgeries. RESULTS A total population of 204 patients (15.43 years) with 341 operated lower limbs (LLs) was analyzed. Dorsiflexion in swing and stance phases significantly improved in all groups postoperatively. The Strayer and the ATL group showed higher postoperative dorsiflexion than the Baumann group. However, no loss of strength was observed with the Baumann method. Maximum power improved in this group postoperatively. An 8.2% loss in calf muscle strength was recorded in the Strayer group. CONCLUSION Operative pes equinus treatment successfully improved the gait of children and adults with CP postoperatively. There were differences in postoperative results between studied operative techniques regarding range of motion and power. LEVEL OF EVIDENCE Level III, retrospective cohort study.

Does patella lowering as part of multilevel surgery improve knee kinematics in children with cerebral palsy and crouch gait? A meta-analysis of comparative studies. J Child Orthop 2024; 18:13-25. [PMID: 38348440 PMCID: PMC10859119 DOI: 10.1177/18632521231217542] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/13/2023] [Accepted: 11/14/2023] [Indexed: 02/15/2024] Open
Abstract
Purpose To evaluate differences in knee kinematic outcomes of patellar-lowering surgery, specifically patellar tendon advancement or patellar tendon shortening, compared with no-patellar-lowering surgery in multilevel surgery for children with cerebral palsy and crouch gait. Methods Four databases were searched to retrieve studies published from inception until 2023. Three reviewers independently screened for studies with observational or randomized control designs, comparing two groups of patients with cerebral palsy and crouch gait who underwent multilevel surgery (with patellar-lowering surgery versus no-patellar-lowering surgery), where various gait analysis outcomes were reported (CRD42023450692). The risk of bias was assessed with the Risk Of Bias In Non-randomised Studies - of Interventions (ROBINS-I) tool. Results Seven studies (249 patients and 368 limbs) met the eligibility criteria. Patients undergoing patellar-lowering surgery demonstrated statistically significant improvements in knee flexion at initial contact (mean difference = -6.39; 95% confidence interval = [-10.4, -2.75]; p = 0.0006; I2 = 84%), minimum knee flexion in stance (mean difference = -14.27; 95% confidence interval = [-18.31, -10.23]; p < 0.00001; I2 = 89%), and clinical knee flexion contracture (mean difference = -5.6; 95% confidence interval = [-9.59, -1.6]; p = 0.006; I2 = 95%), with a significant increase in anterior pelvic tilt (mean difference = 2.97; 95% confidence interval = [0.58, 5.36]; p = 0.01; I2 = 15%). However, improvements in gait deviation index and decrease in peak knee flexion in swing did not reach statistical significance. Subgroup analysis reduced heterogeneity and revealed (1) greater improvement using patellar tendon shortening versus patellar tendon advancement techniques; (2) lack of knee flexion contracture improvement in high-quality or longer-term studies; (3) longer-term improvement only in minimum knee flexion in stance, with a decrease in peak knee flexion in swing; and (4) an inability to assess the potential benefit of rectus femoris procedure and hamstring preservation. Conclusions Overall, the combination of patellar-lowering surgery with multilevel surgery demonstrated superior improvements in stance-phase knee kinematics compared with multilevel surgery alone, despite an increase in anterior pelvic tilt and a longer-term knee flexion reduction during the swing phase. Level of evidence Level III, Systematic review of level III studies.

Abstract
AIM To identify the most frequently reported non-instrumented measures of gait, activity, and participation in children with cerebral palsy (CP) after undergoing gait corrective orthopaedic surgery. METHOD Four databases were searched from database inception to the 9th December 2021 for studies that evaluated functional outcomes for children with CP under 18 years undergoing gait corrective orthopaedic surgery. RESULTS Of 547 citations, 44 publications (n = 3535 participants, n = 1789 males, mean age 10 years 5 months [SD = 3 years 3 months], Gross Motor Function Classification System levels I-III at the time of surgery) were eligible for inclusion. Fourteen different outcome measures were used: one measure of gait, 10 measures of activity, and three measures of participation. Gait was measured with the Edinburgh Visual Gait Scale (EVGS; 4 out of 44). The most common activity and participation measures were the Functional Mobility Scale (FMS; 15 out of 44) and Pediatric Outcomes Data Collection Instrument (11 out of 44) respectively. No studies reported a combination of gait, activity, and participation measures. INTERPRETATION The EVGS and FMS should be considered as core outcome measures in gait corrective orthopaedic surgery, while a measure of participation is unclear. Additional considerations for developing a comprehensive suite of outcomes include identifying a combination of clinical measures and performance-reflective questionnaires that are standardized for children with CP undergoing surgery and meaningful to clinicians and families.

Abstract
Background and Objectives: Single-Event Multi-Level Surgery (SEMLS) is a complex surgical programme in which soft tissue contractures and bony torsional deformities at the ankle, knee and hip, in both lower limbs are surgically corrected during a single operative session, requiring one hospital admission and one period of rehabilitation. The aim of SEMLS is to improve gait and function in ambulant children with cerebral palsy. Utilisation of the SEMLS concept can reduce the number of surgical events, hospital inpatient stays and reduce rehabilitation requirements to a single intensive episode. Three-dimensional gait analysis is a pre-requisite to plan intervention at multiple anatomic levels to correct fixed deformities and to improve gait and function. Materials and Methods: This study was a bibliometric analysis of SEMLS in cerebral palsy using the Clarivate Web of Science Core Collection database from 1900 to 29 May 2023. Results: A total of 84 studies met the inclusion criteria. The most highly cited article was "Correction of severe crouch gait in patients with spastic diplegia with use of multilevel orthopaedic surgery" by Rodda et al. (2006) with 141 citations. The most productive institutions by number of articles were the Royal Children's Hospital Melbourne (Australia), Murdoch Children's Research Institute (Australia) and University of Melbourne (Australia). The most productive author by number of citations was HK Graham (Australia). Conclusions: The literature base for SEMLS consists largely of retrospective cohort studies. The aforementioned three institutes in Melbourne, Australia, which frequently collaborate together, have contributed the greatest number of studies in this field.

Abstract
PURPOSE This study aimed to examine outpatient hospital utilization (number of specialties seen and number of visits to each specialty) in the year after single event multi-level surgery (SEMLS) in children with cerebral palsy (CP), and to determine if utilization differs across the medical center in the year after compared to the year before SEMLS. METHODS This retrospective cross-sectional study used electronic medical record data of outpatient hospital utilization in children with CP who underwent SEMLS. RESULTS Thirty children with CP (Gross Motor Function Classification System Levels I-V, mean age of 9.9 years) were included. In the year after surgery, a significant difference (p = 0.001) was found for the number of specialties seen, with non-ambulatory children seeing more specialties than ambulatory children. No statistically significant difference was found between the number of outpatient visits to each specialty in the year after SEMLS. Compared to the year before SEMLS, fewer therapy visits occurred in the year after SEMLS (p < 0.001) but significantly more visits to orthopaedics (p = 0.001) and radiology (p = 0.001). CONCLUSION Children with CP had fewer therapy visits but more orthopaedic and radiology visits the year after SEMLS. Nearly half of the children were non-ambulatory. Examination of care needs in children with CP undergoing SEMLS is justified with consideration of ambulatory status, surgical burden, and post-operative immobilization.

Abstract
Introduction Most centers in low- to mid-income countries (LMICs) lack facilities for a comprehensive instrumented gait analysis (IGA) which is often considered the preferred method for assessment of the functional results of surgery in children with spastic diplegia. We aimed to study if there were any changes in the Gross Motor Function Classification System (GMFCS) levels and Functional Mobility Scale (FMS) scores after surgery and whether they can be used as an indirect indicator of change in the functional status of a child. Methods This prospective study was conducted at the Pediatric Orthopedic unit of a teaching hospital on spastic diplegic children requiring surgical intervention. GMFCS levels and FMS scores were recorded before the surgery and at each follow-up visit, with the latest record being two years post-surgery. The change in the scores was indicated as an improvement, deterioration, or no change from the baseline and compared to the score of the preceding visit. In addition, it was examined whether the age at surgery had any effect on the temporal change in the scores. Results A total of 25 children were included for analysis after excluding those who failed to fulfill the predefined inclusion and exclusion criteria. Both the GMFCS levels and FMS scores improved from the third month to one-year post-surgery, after which a few patients had a worsening of their scores at the two years follow-up visit. The age at which surgery was performed had no significant effect on the pattern of change in the scores. Most children sought consultations with the physical therapy department only when they visited the surgical team for follow-up. Conclusion This study shows that surgical interventions do improve the functional outcomes in children with spastic CP when assessed using FMS scores while maintaining an undeteriorated GMFCS level in most children. While a peak improvement can be expected one year after surgery in most patients, possible of worsening from baseline scores do exist, and the parents must be informed of the same. Any decision for surgery must involve the parents, and the usefulness of postoperative physical therapy must be impressed upon them before the surgery and during each follow-up visit too.

Abstract
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.

Abstract
INTRODUCTION Single-event multilevel surgery (SEMLS) is frequently used to correct pathological gait patterns in children with bilateral spastic cerebral palsy (BSCP) in a single session surgery. However, in-depth long-term evaluation reports of gait outcomes are limited. Therefore, we investigated if SEMLS is able to correct lower extremity joint and pelvic angles during gait towards typically developing gait patterns (TDC) in children with BSCP, and if so, if this effect is durable over a 10-year period. MATERIALS AND METHODS In total 13 children with BSCP GMFCS level II at time of index-surgery between the ages of 7.7-18.2 years at the time of SEMLS were retrospectively recruited. Three-dimensional gait data were captured preoperatively, as well as at short-, mid-, and long-term post-operatively, and used to analyze: movement analysis profile (MAP), gait profile score (GPS), and lower extremity joint and pelvic angles over the course of a gait cycle using statistical parametric mapping. RESULTS In agreement with previous studies, MAP and GPS improved towards TDCs after surgery, as did knee extension during the stance phase (ɳ2 = 0.67; p < 0.001), while knee flexion in the swing phase (ɳ2 = 0.67; p < 0.001) and pelvic tilt over the complete gait cycle (ɳ2 = 0.36; p < 0.001) deteriorated; no differences were observed between follow-ups. However, further surgical interventions were required in 8 out of 13 of the participants to maintain improvements 10 years post-surgery. CONCLUSIONS While the overall gait pattern improved, our results showed specific aspects of the gait cycle actually deteriorated post-SEMLS and that a majority of the participants needed additional surgery, supporting previous statements for the use of multilevel surgery rather than SEMLS. The results highlight that the field should not only focus on the overall gait scores when evaluating treatment outcomes but should offer additional long-term follow-up of lower extremity function.

Cost savings for single event multilevel surgery in comparison to sequential surgery in ambulatory children with cerebral palsy. Gait Posture 2022; 96:53-59. [PMID: 35576667 DOI: 10.1016/j.gaitpost.2022.05.005] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Revised: 04/20/2022] [Accepted: 05/04/2022] [Indexed: 02/02/2023]
Abstract
BACKGROUND The purpose of this study was to determine the differences in billable provider charges between single event multilevel surgery (SEMLS) based on comprehensive gait analysis and a staged surgical approach (SSA) without comprehensive gait analysis for the orthopedic treatment of ambulatory children with cerebral palsy (CP). METHODS The charges associated with nine common orthopedic surgical combinations (both unilateral and bilateral, soft tissue or soft tissue plus bony) for children with CP were determined and compared between SEMLS and SSA. The charges included surgical, anesthesia, operating room, recovery room, hospital stay, physical therapy, and, for SEMLS only, comprehensive computerized gait analysis. RESULTS Total charges to complete each combination was higher for SSA than for SEMLS. The differential ranged from $10,247 to $75,069 with the percentage difference ranging from 20% to 47%. The mean difference was $43,606 (p = 0.0002). The dollar difference (r = 0.98, p < 0.0001) and percentage difference (r = 0.79, p = 0.01) were both related to the total charge of the SEMLS surgery. SIGNIFICANCE Financial costs are lower for SEMLS vs. SSA for the treatment of multilevel gait issues in children with CP. The cost of gait analysis is much smaller than the cost differential between SEMLS and SSA. Although some patients who have SEMLS may need additional orthopedic surgery with associated costs, this is also possible for SSA. Therefore, due to the many benefits of SEMLS, which also include more informed treatment decision-making as well as reduced time away from school and work (for caregivers), SEMLS guided by gait analysis is recommended over SSA for the treatment of gait disorders in children with CP.

Abstract
BACKGROUND The Edinburgh Visual Gait Score (EVGS) has been used for observational gait assessment in children with cerebral palsy (CP). However, the measurement error of the EVGS and its detailed relationship with gross motor function remain unclear. RESEARCH QUESTIONS This study aimed to confirm the intra-rater and inter-rater reliability as well as the minimal detectable change (MDC) values for the EVGS with the use of the video analysis software and examine the relationship between the EVGS and the Gross Motor Function Measure 66 (GMFM-66) with regard to construct validity. METHODS This cross-sectional study was conducted for 62 children (mean age 11.3 ± 3.9 years) with spastic CP at Gross Motor Function Classification System (GMFCS) level I (32 children), II (25 children) or III (5 children). Three raters independently scored the EVGS using Kinovea video analysis software. The intra-rater and inter-rater reliability were calculated using intra-class correlation coefficients (ICC2,1), and the MDC90 was calculated using standard error of measurement. The construct validity was examined by correlating the EVGS with the GMFM-66. RESULTS The EVGS showed good or excellent reliability within each rater (ICC2,1 = 0.90-0.97) and between raters (ICC2,1 = 0.91). The MDC90 of the EVGS ranged from 3.6 to 6.0. There was a significant correlation between the EVGS and the GMFM-66 (r = - 0.69 to - 0.73, p < 0.001). SIGNIFICANCE The intra-rater and inter-rater reliability of the EVGS is sufficient for observational gait assessment. The high correlation between the EVGS and the GMFM-66 supports its construct validity. The authors propose an MDC of 6.0 for the EVGS. These results can help in the application of EVGS to children with CP at GMFCS level I-II with mild to moderate gait pathology, as there were few children with CP at GMFCS level III.

Abstract
BACKGROUND Advances in pediatric orthopaedic care have improved mobility and function for children with cerebral palsy (CP) as mobility declines from adolescence into adulthood. The long-term effectiveness of modern orthopaedic care is not widely reported. This study aimed to report the pediatric orthopaedic surgical burden, residual deformities, and outcomes using objective evidence of mobility in ambulatory adults with CP. METHODS An institutional review board-approved prospective cohort study was performed in ambulatory adults with CP between 25 and 45 years, who had an adolescent gait analysis. Orthopaedic interventions were reviewed, and adolescent and adult gait analyses were compared using paired 2-tailed t tests. Adults were categorized by the presence of no, mild, or severe residual deformities in rotation, crouch, stiff knee, equinus, and foot deformity. RESULTS Of 106 adults with CP, Gross Motor Function Classification System (GMFCS) distribution was grade I (22%), II (50%), III (23%), and IV (5%). Sixty-one males and 45 females were tested. The average age was 30±4 years with follow-up of 13±4 years since previous analysis; 279 surgical events (1165 procedures) were performed with a mean per patient of 2.6 events and 11 procedures. Comm on procedures were gastrocsoleus complex (88%) and hamstring lengthening (79%). The mean gait deviation index at adolescent and adult visit were 72.7±13 and 72.3±13 (P=0.78). Mean gait velocity at the adolescent visit was 85±27 and 79±31 cm/s at adult visit (P=0.02). Both gait deviation index and gait velocity change were clinically insignificant. Fifty-seven adults (81 limbs, 54%) had mild residual deformities. Residual hip internal rotation, pes planovalgus, and crouch gait were common. Severe deformities impacting function or causing pain were present in 11 participants (14 limbs, 10%). Seven of the 11 adults with severe deformities were worse compared with their adolescent evaluation; 4 were unchanged. CONCLUSIONS Correcting deformities before adulthood has lasting stability with little functional loss in most ambulatory young adults with CP. Increasing deformity after adolescence can occur in young adults but is uncommon. LEVEL OF EVIDENCE Level III.

Abstract
Quantitative data assessment on the basis of three-dimensional gait analysis has been routinely used in the evaluation of pathological gait of children with cerebral palsy. However, a similar quantitative methodology has not been applied for spina bifida patients in whom atypical gait patterns are thought to correlate with various levels of neurological paralysis. The purpose of this study is to investigate the differences among gait patterns in spina bifida between different levels of neurological lesions using quantitative methods: Gait profile score (GPS) and gait variable scores (GVS), scoring subject's gait deviation from a reference. In this cross-sectional study, 22 children with spina bifida (11 women, 11 men; mean age 9.4 years, SD 3.8 years, range 3-17 years), were examined using three-dimensional gait analysis from 2008 to 2018. Physical examination allowed for classification of each of the 44 limbs as either L4, L5 or S1 and comparison with the GPS and GVS using a linear mixed model. GPS and the GVS of the pelvis and hip range of motion in the coronal plane were significantly higher in the L4 group than in the L5 and S1 groups (GPS, P = 0.041, P = 0.003, respectively; GVS of pelvis, P = 0.001, P = 0.001; GVS of hip, P < 0.001, P < 0.001) GVS (foot progression angle) was significantly lower in the S1 group than in L4 and L5 groups (P < 0.001, P = 0.037). We found that GPS and GVS enable us to quantitatively assess the differences among gait patterns between different neurological levels. The scoring tool showed the potential for detecting individual neurological changes.

Abstract
Children with cerebral palsy (CP) are at a high risk of developing foot and ankle deformities that can impact function, brace/shoe fit, and seating. The 3 commonly observed foot and ankle segmental malalignment patterns include equinus, planovalgus, and equinovarus. Assessment of foot deformities is multifaceted, requiring the collection and integration of data from a combination of sources that include the clinical history, standardized physical examination, observational and quantitative gait analysis, GMFCS classification, and radiographic findings. Surgical procedures are determined by identifying all segmental malalignments and assessing the contribution of dynamic or flexible soft-tissue imbalance, fixed soft-tissue imbalance, and skeletal deformities.

Abstract
Purpose This non-randomised controlled trial investigated whether a combined programme of functional physiotherapy and minimally invasive orthopaedic surgery improves the level and degree of capacity and performance of gross motor function in children with spastic cerebral palsy (CP). Methods Fifty-two children with spastic CP aged 5-7 years, Gross Motor Function Classification System (GMFCS) levels II-IV, were allocated to two equal groups: experimental group (selective percutaneous myofascial lengthening [SPML] procedure and 9-month functional strengthening physiotherapy programme) and control (standard physiotherapy) groups. At baseline and at the end of the 9-month intervention, the capacity and performance of gross motor function were assessed with the Gross Motor Function Measure (GMFM) D and E subcategories and Functional Mobility Scale (FMS), respectively. The level of gross motor function was measured with the GMFCS. Results There was a statistically significant difference in the post-intervention improvements in the GMFM D (experimental mean difference = 19.63 ± 10.46; control mean difference = 2.40 ± 4.62) and E (experimental mean difference = 19.33 ± 11.82; control mean difference = 4.20 ± 6.26) between experimental and control group (p < 0.001). There was a significant improvement in the GMFCS level and each FMS distance for the experimental group (p < 0.001), but not for the control group (p > 0.05). Conclusion SPML procedure combined with functional physiotherapy improves gross motor function in children with spastic CP, by raising the degree and level of motor independence.

Abstract
BACKGROUND Patellar height is a valuable measure to evaluate the effect of patellar tendon advancement (PTA) on knee function. In the literature, there is no validated procedure to measure the patellar height. In this study we aimed to (1) determine the patella position through musculoskeletal modeling, (2) investigate the effects of two surgical procedures applied for PTA, and (3) assess the effect of PTA in combination with single-event multilevel surgery (SEMLS) on the knee kinematics of patients with cerebral palsy (CP) and crouch gait. METHOD Three-dimensional gait and X-ray data of children with CP and crouch gait were retrospectively analyzed if they had received a SEMLS in combination with PTA (PTA group, n = 18) or without PTA (NoPTA group, n = 18). A computational musculoskeletal model was used to quantify patella position, knee extension moment arm, and knee kinematics pre- and postoperatively. RESULTS Patellar height significantly decreased in the PTA group (P = 0.004), while there was no difference in the NoPTA group (P > 0.05). The bony procedure for PTA provided a better Insall-Salvati ratio than the soft tissue procedure. The peak knee extension moment arm significantly increased in the PTA group (P = 0.008). In terms of postoperative knee joint kinematics, the PTA group was closer to typically developed children than the NoPTA group. CONCLUSION Musculoskeletal modeling was found to be an effective tool for the determination of the patellar height. PTA improved the patella position, knee extension moment arm, and knee kinematics and was an effective procedure for the surgical management of crouch gait in patients with CP.

The Ability to Run in Young People with Cerebral Palsy before and after Single Event Multi-Level Surgery. J Pers Med 2021; 11:jpm11070660.

Abstract
The objective of the study is to identify and evaluate possible factors that influence the ability to run before and after single event multi-level surgery (SEMLS). Young patients (6–25 years) with spastic cerebral palsy (GMFCSI-II) were retrospectively included. Type and number of surgical procedures, time for recovery and 3D gait analysis variables were analyzed with respect to the ability to run. In total, 98 patients (38 females; 60 males) who received SEMLS (12 years, SD 3.4) were included and compared to a control group of 71 conservatively treated patients. Of 60 runners pre-surgery, 17 (28%) lost the ability, while gained in 8 of 38 (21%) non-runners. The number of surgical procedures was a significant predictor and those who lost their ability to run had significantly more (mean = 5.9, SD = 1.7), compared to the patients who gained the ability (mean = 3.5, SD = 0.9). Further, pre-surgical function (e.g., gait speed) was significantly different (p < 0.001). Pre-surgical function and the number of surgical procedures seem to play an important role for the gain or loss of the ability to run after surgery. Caution is warranted in patients with lower pre-surgical function and the ability to run, as they seem at a higher risk to lose the ability.

Abstract
ABSTRACT The aim of this study was to compare outcomes for single-event multilevel surgery (SEMLS) in cerebral palsy (CP) performed by 1 or 2 attending surgeons.A retrospective review of patients with CP undergoing SEMLS was performed. Patients undergoing SEMLS performed by a single senior surgeon were compared with patients undergoing SEMLS by the same senior surgeon and a consistent second attending surgeon. Due to heterogeneity of the type and quantity of SEMLS procedures included in this study, a scoring system was utilized to stratify patients to low and high surgical burden. The SEMLS events scoring less than 18 points were categorized as low burden surgery and SEMLS scoring 18 or more points were categorized as high burden surgery. Operative time, estimated blood loss, hospital length of stay, and operating room (OR) utilization costs were compared.In low burden SEMLS, 10 patients had SEMLS performed by a single surgeon and 8 patients had SEMLS performed by 2 surgeons. In high burden SEMLS, 10 patients had SEMLS performed by a single surgeon and 12 patients had SEMLS performed by 2 surgeons. For high burden SEMLS, operative time was decreased by a mean of 69 minutes in cases performed by 2 co-surgeons (P = 0.03). Decreased operative time was associated with an estimated savings of $2484 per SEMLS case. In low burden SEMLS, a trend toward decreased operative time was associated for cases performed by 2 co-surgeons (182 vs 221 minutes, P = 0.11). Decreased operative time was associated with an estimated savings of $1404 per low burden SEMLS case. No difference was found for estimated blood loss or hospital length of stay between groups in high and low burden SEMLS.Employing 2 attending surgeons in SEMLS decreased operative time and OR utilization cost, particularly in patients with a high surgical burden. These findings support the practice of utilizing 2 attending surgeons for SEMLS in patients with CP.Level of Evidence: Level III.

Abstract
The femoral derotation osteotomy (FDO) is seen as the golden standard treatment in children with cerebral palsy and internal rotated gait. This study provides quantitative evidence in support of the beneficial effect of FDO after long term follow up.
Retrospective clinical and kinematic evaluation of 31 CP patients (55 operated limbs) pre-, 1 and 3 years postoperatively after proximal FDO was conducted for a minimal follow-up of 3 years. This group con- sisted of 20 men and 11 women, aged 10.68±3.31 years at the time of surgery. Minimum follow up was 3 years (3.16±0.53 years), with 22 patients (38 operated limbs) having an additional follow up at 5 years (5.02±0.49 years). Age at FU3 and FU5 was 14.06±3.52 years and 15.39±3.08 years respectively.
A set of clinical and kinematic parameters were ana- lyzed and showed a significant correction of mean hip rotation and femoral anteversion after FDO. Further plotting of individual data comparing 3 or 5 year postoperative values to 1 year postoperative values showed no further significant changes, indicating sustained correction of internally rotted gait until end of our follow up. Plotting mean hip rotation in stance as well as kinematic knee parameters according to age grouped cohorts could not show age at time of surgery to be a significant factor in recurrence of internally rotated gait or preoperative disturbances of knee motion in the sagittal plane.
This study provides quantitative evidence on the beneficial effect of FDO, a surgical technique to improve internally rotated gait in cerebral palsy patients with spastic diplegia.
Pre- and postoperative clinical and kinematic parameters are compared and results are discussed.
Minimum follow up was 3 years with a mean follow up of 4.65±0.83 years. The effect of age at time of surgery on recurrence and kinematic parameters were studied.

Abstract
This article presents a classification of lower limb musculoskeletal pathology (MSP) for ambulant children with cerebral palsy (CP) to identify key features from infancy to adulthood. The classification aims to improve communication, and to guide referral for interventions, which if timed appropriately, may optimise long-term musculoskeletal health and function. Consensus was achieved by discussion between staff in a Motion Analysis Laboratory (MAL). A four-stage classification system was developed: Stage 1: Hypertonia: Abnormal postures are dynamic. Stage 2: Contracture: Fixed shortening of one or more muscle-tendon units. Stage 3: Bone and joint deformity: Torsional deformities and/or joint instability (e.g., hip displacement or pes valgus), usually accompanied by contractures. Stage 4: Decompensation: Severe pathology where restoration of optimal joint and muscle-tendon function is not possible. Reliability of the classification was tested using the presentation of 16 clinical cases to a group of experienced observers, on two occasions, two weeks apart. Reliability was found to be very good to excellent, with mean Fleiss' kappa ranging from 0.72 to 0.84. Four-stages are proposed to classify lower limb MSP in children with CP. The classification was reliable in a group of clinicians who work together. We emphasise the features of decompensated MSP in the lower limb, which may not always benefit from reconstructive surgery and which can be avoided by timely intervention.

Abstract
INTRODUCTION Children with spastic diplegic cerebral palsy (CP) often have functional and gait impairments related to spasticity and loss of range of motion (ROM). Selective dorsal rhizotomy (SDR) and single-event multilevel surgery (SEMLS) are surgical interventions that are used to manage spasticity and functional gait impairments, respectively. This is the first known case report of a child with spastic diplegic CP who underwent combined SDR and SEMLS. CASE REPORT Our patient is a 7-year-old girl with spastic diplegic CP, functioning at the Gross Motor Function Classification System (GMFCS) level II, who presented with spasticity and contractures in bilateral lower extremities leading to functional gait impairments, despite conservative management. Combined SDR/SEMLS was offered with the goal of simultaneously managing spasticity and contractures while reducing the need for multiple procedures. Postoperatively, the patient's functional mobility, ROM, spasticity, and strength were assessed at various follow-up intervals. The patient had increased lower extremity weakness and functional decline postoperatively. Persistent genu recurvatum and knee instability required prolonged rehabilitation services, and she demonstrated functional gains with these interventions. At follow-ups, spasticity was resolved and ROM improved. By the 12-month follow-up, the Gross Motor Function Measure-66 was improved to 68.9 (55th percentile) from the preoperative level of 62.1 (35th percentile). By the 30-month follow-up, she was able to participate in novel recreational activities. DISCUSSION/CONCLUSION Multidisciplinary teams may consider combined SDR/SEMLS for management of spasticity, gait impairment, and contracture in carefully selected patients with spastic CP.

Abstract
Spastic Cerebral Palsy (CP) is the most common form of CP, comprising of 80% of all cases. Spasticity is a type of hypertonia that clinically manifests as dynamic contractures. The dynamic contracture along with the reduced level of physical activity in a child with CP leads to secondary structural and morphological changes in spastic muscle, causing real musculotendinous shortening, known as fixed contractures. When fixed muscle contractures are not treated early, progressive musculoskeletal deformities develop. As a consequence, spastic CP from a static neurological pathology becomes a progressive orthopaedic pathology which needs to be managed surgically. Orthopaedic surgical management of CP has evolved from previous "multi-event single level" procedures to a "single event multilevel" procedures, with changes in selection and execution of treatment modalities. There is increasing evidence that multilevel surgery is an integral and essential part of therapeutic management of spastic CP, but more research is needed to ensure effectiveness of this intervention on all domains of physical disability in CP.

Abstract
Zusammenfassung
Hintergrund
Schäden des 1. Motoneurons führen zu spastischen Lähmungen an den Extremitäten, die bei Kindern und Erwachsenen einschneidende Veränderungen der Bewegungsfähigkeit zur Folge haben und Lebensqualität sowie -teilhabe durch Funktionsverlust und Schmerzen einschränken.
Methode
Auf Grundlage eigener Behandlungserfahrungen in Verbindung mit einer PubMed-Literaturrecherche werden aktuelle Diagnose- und Behandlungsverfahren sowie deren Kombinationen vorgestellt.
Ergebnisse
Prinzipiell stehen Physio- und Ergotherapie mit vereinbarten alltagsrelevanten Therapiezielen, Medikamente (Botulinumtoxin und Baclofen) und Orthetik im Vordergrund. Chirurgische Maßnahmen an Muskeln, Sehnen, Gelenken und Knochen können dem betroffenen Patienten zu verbesserter Beweglichkeit, Wachstumskorrektur und vereinfachter Alltagsbewältigung verhelfen. Die selektive Neurektomie bei fokaler Spastik erlebt derzeit eine Renaissance. Die intrathekale Baclofentherapie kann bei entsprechend hoher Katheterlage auch eine Tonusreduktion an der oberen Extremität erreichen.

Abstract
PURPOSE Equinus is the most common deformity in cerebral palsy (CP) and gastrocsoleus lengthening (GSL) is the most commonly performed surgery to improve gait and function in ambulatory children with CP. Substantial variation exists in the indications for GSL and surgical technique. The purpose of this study was to review surgical anatomy and biomechanics of the gastrocsoleus and to utilize expert orthopaedic opinion through a Delphi technique to establish consensus for surgical indications for GSL in ambulatory children with CP. METHODS A 17-member panel, of Fellowship-trained paediatric orthopaedic surgeons, each with at least 9 years of clinical post-training experience in the surgical management of children with CP, was established. Consensus for the surgical indications for GSL was achieved through a standardized, iterative Delphi process. RESULTS Consensus was reached to support conservative Zone 1 surgery in diplegia and Zone 3 surgery (lengthening of the Achilles tendon) was contraindicated. Zone 2 or Zone 3 surgery reached general agreement as a choice in hemiplegia and under-correction was preferred to any degree of overcorrection. Agreement was reached that the optimum age for GSL surgery was 6 years to 10 years and should be avoided in children aged under 4 years. Physical examination measures with the child awake and under anaesthesia were important in decision making. Gait analysis was supported both for decision making and for assessing outcomes, in combination with patient reported outcomes (PROMS). CONCLUSIONS The results from this study may encourage informed practice evaluation, reduce practice variability, improve clinical outcomes and point to questions for further research.

Abstract
BACKGROUND Flexed knee gait is a common gait dysfunction in individuals with bilateral spastic cerebral palsy (BSCP) and is often addressed with single event multilevel surgery (SEMLS). SEMLS has been shown to have positive short-term effects especially on sagittal knee joint kinematics with less knee flexion during stance phase. However, mid- and long-term observations are rare, and results are reported in discrete parameters or summary statistics where temporal aspects are not considered. RESEARCH QUESTION Does the improved knee joint kinematics after patellar tendon shortening (PTS) as part of SEMLS persist in the long-term in individuals with BSCP? METHODS Data of instrumented gait analysis of twelve participants (females/males: 5/7, mean age: 15.3 ± 3.4 years) with BSCP treated with PTS as part of SEMLS were retrospectively analyzed. Participants had had follow-up gait analysis 1, 5 and 7 years or more after surgery. Three-dimensional lower extremity kinematics of walking at a self-selected speed were collected using a 12-camera motion capture system and 4 embedded force plates. One-dimensional statistical parametric mapping (SPM) was used for data analysis, permitting time point comparisons of continuous data. RESULTS Time point comparison revealed no significant differences in the sagittal plane for knee joint kinematics (p > 0.05) over the tree measurement time points. Hip and ankle joint kinematics as well as normalised walking speed remained stable over the observation period. SIGNIFICANCE This is the first study investigating lower extremity kinematics in patients with BSCP and flexed knee gait after SEMLS with SPM. Results demonstrate that positive effects on sagittal knee joint kinematics of PTS as part of SEMLS persist up to 9 years after surgery and progressivity does not reoccur. Thus, if clinical examination indicates an operation in individuals with BSCP, improved kinematics through SEMLS persist into adulthood. With the relatively new statistical procedure SPM gait can be displayed and analysed in established joint angle curves making them easier to understand (e.g. physiotherapists, movement scientists, physicians).

Abstract
BACKGROUND This long-term consecutive, retrospective single-center cohort study evaluates long-term outcomes of single-event multilevel surgery in diplegic cerebral palsy with respect to functional status, gait, and patient satisfaction. METHODS All patients with diplegic cerebral palsy who underwent single-event multilevel surgery >10 years previously were included. Retrospective gait assessment was performed using the Edinburgh Visual Gait Score (EVGS) and Gillette Functional Assessment Questionnaire Walking Scale (FAQWS) preoperatively and at midterm postoperative follow-up (median 2.6 y) and prospectively at most recent review [median 18 y, interquartile (IQ) range: 14.4 to 20.5 y]. The Short Form-36 (SF-36) was used prospectively to evaluate outcome compared with population norms for adults from the UK. RESULTS The complete assessment was possible in 26 of 39 patients who met the inclusion criteria. There was a statistically significant improvement at most recent follow-up compared with the preoperative assessment for EVGS and FAQWS [Wilcoxon Matched Pairs Signed Rank test -4.42 (P<0.0001) and 3.98 (P=0.0001), respectively]. The median Physical Health and Mental Health Component Summary scores for the SF-36 were 43.0 (IQ range: 32.8 to 46.8) and 55.3 (IQ range: 46.1 to 61.1), respectively. CONCLUSIONS This study demonstrates significant long-term improvements in function, independence and patient satisfaction that continue into adulthood. This will inform discussions with patients and families considering this treatment option. LEVEL OF EVIDENCE Level IV-Retrospective cohort study.

Abstract
Background Lower limb serial casting is commonly used therapeutically in paediatric clinical practice with some evidence to support its efficacy. This systematic review aimed to determine the effects of serial casting in isolation or combination with other therapies for the management of lower limb dysfunction in children with Cerebral Palsy (CP). Methods A systematic literature search was conducted in February 2019 across eight databases (PUBMED, EMBASE, CINAHL, PEDro, OTSeeker, Cochrane, Scopus and Proquest) using key terms ‘Cerebral Palsy’ and ‘serial casting’ and associated synonyms. A meta-synthesis and meta-analysis were undertaken when sufficient results were available showing the effect of serial casting on functional outcomes including: Ankle range of motion; neurological measures of hypertonicity and spasticity, functional gait measures and; gross motor function. Results Twenty-five articles from 3219 possible citations were included. Serial casting was found to be effective for: Improving ankle dorsiflexion (DF) passive range of motion (PROM) in the immediate to short-term, decreasing hypertonicity measured by Modified Ashworth Scale (MAS) in the short-term and, enhancing functional gait outcomes in the mid-term. Serial casting with or without botulinum toxin type-A (BTX-A) did not significantly affect gross motor capacity measured by Gross Motor Function Measure (GMFM). Serial casting with pharmacological intervention achieved significantly more DF PROM than serial casting alone (MD − 3.19 degrees; 95% CI − 5.76 to − 0.62; P = 0.01; I2 = 0%), however the clinical importance of improving ankle DF PROM by an additional three degrees remains unclear. Conclusions Lower limb serial casting, improves several outcomes relevant to lower limb function supporting its clinical use for improving DF PROM, reducing hypertonicity and improving gait in children with CP. Further research using stronger methodological study designs, is indicated to explore long-term effects of serial casting on functional lower limb outcomes such as gross motor function in children with CP. Clinicians can use this information when developing individualised treatment plans for children who have CP during shared decision-making consultations.

Abstract
BACKGROUND ε-Aminocaproic acid (EACA) is an antifibrinolytic agent that has been shown to decrease blood loss and transfusion requirements in several populations undergoing various surgical procedures. However, the efficacy of EACA has not been assessed in pediatric patients with cerebral palsy undergoing bilateral varus rotational femoral osteotomies. The purpose of this study was to assess the efficacy of intravenous EACA in reducing calculated intraoperative blood loss and transfusions in this population. METHODS Patients aged 18 years or younger were eligible. Patients were randomized to receive EACA or placebo (saline), and randomization was stratified based on sex and whether or not additional soft tissue or osseous procedures were performed. On the basis of retrospective data, the calculated sample size was 12 patients per arm to detect a difference of 250-mL blood loss. The primary outcome was calculated intraoperative blood loss. Secondary outcomes included transfusion requirements, 24-hour drain output, length of stay, and incidence of complications. RESULTS The mean age of patients in this study was 8 years (SD: 2.4 y). There were no differences in age, sex, height, weight, type of anesthesia, operative time, and associated procedures between the EACA and placebo groups (P>0.05). Preoperative hematocrit was lower in the EACA group (37.1 vs. 40.0, P=0.04). Calculated intraoperative blood loss was 536 mL in the EACA group and 628 mL in the placebo group (P=0.45). Transfusions were required in 62% of patients in the EACA group and 67% of patients in the placebo group (P=0.68). Total 24-hour drain output was 72.5 mL in the EACA group and 103.3 mL in the placebo group (P=0.37). Length of stay was similar between both groups, and there were no drug or placebo-related complications in either group. CONCLUSIONS There was no difference in blood loss or transfusion requirements associated with EACA compared with placebo; however, this study is underpowered to detect smaller differences in blood loss. Additional studies with larger sample sizes are needed to confirm these findings and further elucidate the indications for antifibrinolytic agents in pediatric patients. LEVEL OF EVIDENCE Level I.

Abstract
AIM To explore how patients with cerebral palsy (CP) perceive their gait and evaluate associations between subjective gait perception and: objective gait parameters, endurance, pain, and fatigue. METHOD Sixty-two patients (21 females and 41 males; mean [SD] age 20y [5y 1mo], range 15-29y) performed a clinical gait analysis. Self-selected walking speed, Gait Profile Score, and Gait Variable Score were calculated. Subjective gait perception was assessed with a visual analogue scale using the question: 'On a scale from 0 (worst) to 10 (optimal), how would you describe your walking today?'. A 6-minute walk test (6MWT) measured endurance; the 36-Item Short Form Health Survey (SF-36) evaluated quality of life. T-tests, Pearson correlations, and univariate and multiple linear regression models were used to compare and find associations between the data. RESULTS Overall mean (SD) subjective gait perception was 7.5 (1.8) and was significantly higher for patients in Gross Motor Function Classification System (GMFCS) level I (7.9 [1.5]) than for patients in GMFCS levels II and III (5.9 [2.0]). Positive correlations were found between subjective gait perception and gait scores, walking speed, 6MWT distance, and SF-36 score. Only walking speed was a significant predictor of subjective gait perception. INTERPRETATION Subjective gait perception was influenced by GMFCS level and linked partially with the walking speed. The gait quality did not explain subjective gait perception. It is important to combine subjective and objective gait scores to develop personalized therapeutic goals. WHAT THIS PAPER ADDS Subjective gait perception is influenced by the physical impairment levels of patients with cerebral palsy. Subjective gait perception and objective gait scores are associated. Walking speed is the only predictor of gait perception.

Abstract
BACKGROUND The optimal management of impaired knee joint function in patients with cerebral palsy (CP) remains a significant and ongoing challenge in paediatric orthopaedic surgery. RESEARCH QUESTION What are the clinical and functional outcomes after operative and non-operative orthopaedic interventions for knee joint impairment in patients with CP? METHODS This systematic review and meta-analysis of orthopaedic interventions for the management of knee joint impairment in paediatric CP patients evaluated study-level data in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement. We performed searches of the following electronic databases from their dates of inception to November 2019: Medline (Ovid), Embase (Ovid) and Pubmed. We extracted mean differences in pre-operative and post-operative measurements for the following outcomes: minimum knee flexion in stance; knee flexion at initial contact; maximum knee flexion in swing; range of motion; popliteal angle; fixed flexion deformity angle; and mean pelvic tilt. RESULTS Sixty-nine retrospective cohort studies, prospective cohort studies and RCTs comprising 2991 patients were included with 4578 knees analysed. Included studies were of sufficient quality as assessed by the MOOSE checklist. Operative interventions showed significant improvement in knee flexion at initial contact, knee flexion in stance, range of motion, popliteal angle and fixed flexion deformity which were comparable when subgrouped according to operative technique. In contrast, non-operative techniques and botulinum toxin injection did not confer significant improvements. Operative interventions for knee joint impairment led to increased mean pelvic tilt and reduced maximum knee flexion in swing. SIGNIFICANCE This review provides strong evidence that operative interventions for the management of knee joint impairment in cerebral palsy patients improve knee kinematics and clinical examination findings.

Abstract
PURPOSE This study investigates functional and technical outcomes to support an early mobilization approach to rehabilitation after single-event multilevel surgery (SEMLS) for children with cerebral palsy (CP), and disseminates innovative guidelines emphasizing early walking. METHODS Twenty-three participants with spastic diplegic CP ages 7 through 17 years, Gross Motor Function Classification System levels I to III, who underwent an early mobilization program after SEMLS were reviewed. Outcomes were examined from motion analysis data and clinical documentation. RESULTS All participants were able to return to school walking at discharge. At 1-year postoperatively, participants had returned to their prior walking level or better. Change in Gait Deviation Index and Pediatric Outcomes Data Collection Instrument indicated improvements in functional mobility and gait consistent with or greater than the literature. CONCLUSION This intensive early mobilization program restores participation in daily activities, walking, and school within the first month postoperatively.

Single-event multilevel surgery, but not botulinum toxin injections normalize joint loading in cerebral palsy patients. Clin Biomech (Bristol, Avon) 2020; 76:105025. [PMID: 32402900 DOI: 10.1016/j.clinbiomech.2020.105025] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/16/2019] [Revised: 04/20/2020] [Accepted: 04/28/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND Many patients with cerebral palsy present a pathologic gait pattern, which presumably induces aberrant musculoskeletal loading that interferes with natural bone growth, causing bone deformations on the long term. Botulinum toxin interventions and single-event multilevel surgeries are used to restore the gait pattern, assuming that a normal gait pattern restores musculoskeletal loading and thus prevents further bone deformation. However, it is unknown if these interventions are able to restore musculoskeletal loading. Hence, we investigated the impact of botulinum toxin injections and single-event multilevel surgery on musculoskeletal loading. METHODS Gait data collected in 93 children with bilateral cerebral palsy, which included pre- and post multi-level botulinum toxin (49 children) and single-event multilevel surgery (44 children) assessments, and 15 typically developing children were retrospectively processed using a musculoskeletal modelling workflow to calculate joint angles, moments, muscle and joint contact force magnitudes and orientations. Differences from the typically developing waveform were expressed by a root-mean square difference were compared using paired t-tests for each intervention separately (alpha <0.05). FINDINGS Botulinum toxin induced significant changes in the joint angles, but did not improve the muscle and joint contact forces. Single-event multilevel surgery induced significant kinematic and kinetic changes, which were associated with improved muscle and joint contact forces. INTERPRETATION The present results indicate that botulinum toxin injections were not able to restore normal gait kinematics nor musculoskeletal loading, whereas single-event multilevel surgery did successfully restore both. Therefore, single-event multilevel surgery might be protective against the re-occurrence of bone deformation on the longer term.

Abstract
PURPOSE Assessment of surgical treatments on gait in patients with bilateral cerebral palsy (CP) is often performed in short-term studies. The purpose of this study was to analyze the influence of single-event multilevel surgery (SEMLS) on long-term evolution of gait using gait deviation index (GDI) and walking speed. METHODS In all, 28 patients with bilateral CP (Gross Motor Function Classification System I to III) with two clinical gait analyses (CGA) were included (mean age: 9.0 years (sd 2.9) at the first CGA, 19.6 years (sd 4.1) at the last, all of them at skeletal maturity). GDI, walking speed and their changes were calculated. Statistical analysis was performed to observe differences between baseline and follow-up CGA. Pearson's correlations were conducted to evaluate the associations between GDI and walking speed changes with: GDI at baseline and walking speed at baseline. GDI and walking speed evolution have been analyzed for two groups of patients: with and without SEMLS. RESULTS Regardless of the treatment, GDI was significantly higher at follow-up CGA (baseline: 73.1 (sd 13.1) versus follow-up: 80.1 (sd 13.2); p = 0.014). Significant negative correlations were found between GDI change and GDI at baseline (r = -0.52; p = 0.004) and between walking speed change and walking speed at the baseline (r = -0.70; p < 0.001). Regarding the group of patients with or without SEMLS, only significant improvement of GDI was found for patients with SEMLS (at baseline: 69.0 (sd 12.1) versus follow-up: 77.8 (sd 11.2); p < 0.05). CONCLUSION Analysis at skeletal maturity showed a gait quality maintained for patients without SEMLS and an improvement for patients with SEMLS. LEVEL OF EVIDENCE Level III.

Abstract
Many surgical options have been proposed to improve the ambulatory status of children with spastic cerebral palsy (CP), but none have focused on addressing both spasticity and lower extremity tendon contractures. The purpose of this study is to evaluate the results of selective dorsal rhizotomy (SDR) followed by minimally invasive tendon lengthening allowing immediate return to ambulation. Two hundred fifty-five spastic CP patients (who received SDR procedure at an average age of 6.9±2.6 years and tendon lengthening procedure at an average age of 7.2±2.5 years) were retrospectively reviewed. Patients were grouped by the gross motor function classification system (GMFCS) 1-3 and 4-5. Kaplan-Meier analysis and Cox proportional hazard model using a requirement for additional tendon lengthening as an end point were conducted. Tendon lengthening followed SDR at an average of 4.3±10.7 months. On an average of 4.9±1.2 years after tendon lengthening, GMFCS was improved in 28 and maintained in 213 patients, respectively. There was no difference of variables and joint angles between the two GMFCS groups. A repeat tendon lengthening was required in 19 patients. The Kaplan-Meier analysis showed 81% success rate. Cox proportional hazard model identified age at tendon lengthening [hazards ratio (HR), 0.53; 95% confidence interval (CI), 0.37-0.76] and duration between SDR and tendon lengthening of more than 6 months (HR, 2.96; 95% CI, 1.05-8.33) associated with need for a repeat tendon lengthening procedure. Our novel approach of SDR/tendon lengthening results in improved joint angles as well as stable or improved GMFCS. Longer follow-up is necessary to determine if this approach could prolong ambulatory ability and reduced need for more invasive orthopedic surgeries.

Abstract
BACKGROUND Children's ability to control the speed of gait is important for a wide range of activities. It is thought that the ability to increase the speed of gait for children with cerebral palsy (CP) is common. This study considered 3 hypotheses: (1) most ambulatory children with CP can increase gait speed, (2) the characteristics of free (self-selected) and fast walking are related to motor impairment level, and (3) the strategies used to increase gait speed are distinct among these levels. METHODS A retrospective review of time-distance parameters (TDPs) for 212 subjects with CP and 34 typically developing subjects walking at free and fast speeds was performed. Only children who could increase their gait speed above the minimal clinically important difference were defined as having a fast walk. Analysis of variance was used to compare TDPs of children with CP, among Gross Motor Function Classification System (GMFCS) levels, and children in typically developing group. RESULTS Eight-five percent of the CP group (GMFCS I, II, III; 96%, 99%, and 34%, respectively) could increase gait speed on demand. At free speed, children at GMFCS I and II were significantly faster than children at GMFCS level III. At free speed, children at GMFCS I and II had significantly greater stride length than those at GMFCS levels III. At free speed, children at GMFCS level III had significantly lower cadence than those at GMFCS I and II. There were no significant differences in cadence among GMFCS levels at fast speeds. There were no significant differences among GMFCS levels for percent change in any TDP between free and fast walking. DISCUSSION Almost all children with CP at GMFCS levels I and II can control the speed of gait, however, only one-third at GMFCS III level have this ability. This study suggests that children at GMFCS III level can be divided into 2 groups based on their ability to control gait speed; however, the prognostic significance of such categorization remains to be determined.

Abstract
BACKGROUND The aim of this study was to review available evidence for physical therapy treatment (PTT) after single-event multilevel surgery (SEMLS), and to realize a first step towards an accurate and clinical guideline for developing effective PTT for children with cerebral palsy (CP) after SEMLS. METHODS A qualitative systematic review (PubMed, Medline, Embase, CINAHL, and the Cochrane Library) investigating a program of PTT after SEMLS in children aged 4-18 years with CP classified by Gross Motor Function Classification System level I-III. RESULTS Six articles meeting the inclusion criteria were selected. The selected studies provide only incomplete descriptions of interventions, and show no consensus regarding PTT after SEMLS. Neither do they show any consensus on the outcome measures or measuring instruments. CONCLUSIONS Based on the results of this literature review in combination with our best practice, we propose a preliminary protocol of PTT after SEMLS.

Abstract
CONTEXT Multilevel surgery (MLS) is standard care for reducing musculoskeletal disorders among children with spastic cerebral palsy (CP). OBJECTIVE To summarize the literature examining effects of MLS and satisfaction with MLS for children with CP. DATA SOURCES Medline, Embase, Cumulative Index to Nursing and Allied Health Literature, and Cochrane Central Register of Controlled Trials were searched. STUDY SELECTION Studies in which authors reported effects of or satisfaction with MLS in children with CP were selected. DATA EXTRACTION Two authors screened and extracted data on gross motor function, gait speed, gait (eg, Gait Profile Score), range of motion, strength, spasticity, participation, quality of life, satisfaction, and adverse events. RESULTS Seventy-four studies (3551 participants) were identified. One was a randomized controlled trial (RCT) (n = 19); the remainder were cohort studies. Pooled analysis of cohort studies revealed that MLS did not have a long-term effect on gross motor function (standardized mean difference [SMD]: 0.38; 95% confidence interval [CI]: -0.25 to 1.01) or gait speed (SMD: 0.12; 95% CI: -0.01 to 0.25) but did improve gait (SMD: -0.80; 95% CI: -0.95 to -0.65). The RCT also revealed no effect of MLS on gross motor function but improvements in the Gait Profile Score at 1 year. Participation and quality of life were reported in only 5 studies, and adverse events were adequately reported in 17 studies. LIMITATIONS Data were largely from cohort studies. CONCLUSIONS Findings reveal that gait, but not gross motor function, improves after MLS. RCTs and improved reporting of studies of MLS are required.

Abstract
AIM To review the potential predictors of outcome after single-event multilevel surgery (SEMLS) in children with cerebral palsy (CP). METHOD A literature search using the following criteria was performed in six electronic databases: (1) children with cerebral palsy; (2) analysed potential predictors of outcome after SEMLS; (3) minimum 12 months follow-up. The potential predictors were predefined: sex; topographical distribution; socio-economic status; Gross Motor Function Classification System (GMFCS) level; preoperative kinematic summary statistic; age at surgery. Study quality was appraised with the methodological index for non-randomized studies (MINORS) and the Oxford Centre for Evidence-Based Medicine scale. RESULTS Of the seven studies identified, the MINORS scores ranged from 9 to 11 and all were graded 2b on the Oxford Centre for Evidence-Based Medicine scale. There was little or no evidence to support sex, topographical distribution, or socio-economic status as predictive factors after SEMLS. Preoperative Gait Profile Score (GPS) was the best measure of expected improvement in gait kinematics. Parent-reported satisfaction and GPS were best after SEMLS in children graded GMFCS II. The best long-term results were seen in those aged between 10 years and 12 years of age. INTERPRETATION The candidate who might expect to realize the most improvement from SEMLS is aged between 10 years and 12 years, is in GMFCS level II, and has a poor preoperative GPS. WHAT THIS PAPER ADDS Children aged 10 to 12 years, in Gross Motor Function Classification System level II, with a poor preoperative Gait Profile Score might expect to realize the most improvement after single-event multilevel surgery.

Abstract
Objective To investigate rehabilitation treatment cost of patients with cerebral palsy (CP) according to age. Methods We analyzed the cost of rehabilitation treatment from 2007 to 2013 for patients diagnosed with CP by sourcing data from the National Health Information Database. Results While the number of recently born children requiring rehabilitation treatment has decreased, the number of patients requiring this treatment in other age groups has gradually increased. In addition, annual physical therapy, occupational therapy, hydrotherapy, and botulinum toxin injection treatment costs per person have increased. On the other hand, the number of orthopedic surgeries and selective dorsal rhizotomy performed has decreased. Conclusion This study investigated trends in the cost of treatment for patients with CP. This study can be used as a basis to provide treatment support for patients with CP.

Abstract
BACKGROUND Children with cerebral palsy are at risk of developing muscle contractures, often contributing to pain, structural deformities and mobility limitations. With the increasing use of gait indices to summarise the findings of three dimensional gait analysis (3DGA), the purpose of this study is to determine whether there is a relationship between multilevel joint contractures and the Gait Profile Score in children with cerebral palsy. METHODS The Gait Profile Score, calculated from 3D gait analysis, and passive range of motion, strength and spasticity of the hips, knees and ankles in the sagittal plane were measured in 145 children with cerebral palsy (mean age:11 years,4 months; SD:2 years,10 months) (83 males) enrolled in the NSW Paediatric Gait Analysis Service Research Registry from 2011 to 2016. The relationships between these physical measures and the Gait Profile Score were explored using bivariate and multivariate correlations. FINDINGS Reduced hip extension, knee extension and ankle dorsiflexion (knee extended) range of motion were correlated with a higher (worse) Gait Profile Score (r = -0.348 to -0.466, p < .001). Children with all joints contracted had a significantly higher Gait Profile Score (mean 17.5°, SD 6.2°) than those with no contractures (mean 11.0°, SD 2.3°) or ankle contractures only (mean 12.8°, SD 5.1°) (p < .05). Knee flexion weakness, reduced hip extension and ankle dorsiflexion (knee extended) range of motion predicted 47% of the Gait Profile Score. INTERPRETATION The Gait Profile Score is a sensitive measure for demonstrating the relationship between multilevel sagittal plane joint contractures and kinematic gait. Clinically, this supports the use of the Gait Profile Score as a simplified measure to understand the contribution of contractures to functional gait limitations. Monitoring knee flexion strength, and hip extension and ankle dorsiflexion (knee extended) range of motion may assist clinicians in prioritising interventions to improve gait in this population.

Abstract
BACKGROUND Deterioration of gait in adolescent and adult patients with cerebral palsy can be associated with multiple factors. Multilevel surgery (MLS) is one option in adults with cerebral palsy to improve gait function with encouraging short-term results. It is a question whether these improvements are maintained over time. METHODS In a retrospective consecutive cohort study, adults with bilateral spastic cerebral palsy (BSCP) treated with MLS between 1995 and 2011 were scanned for potential inclusion. Patients needed to fulfill the following inclusion criteria: age at MLS > 17, standardized three-dimensional gait analysis (3D-GA) including clinical examination at pre-operative (E0), a short-term follow-up (E1) and at least seven years (E2) after the index MLS. Twenty adults (10 women, 10 men) with a Gross Motor Function Classification Level (GMFCS) I-III and a mean age at MLS of 24.8 years were included in this study. The average long-term follow-up was 10.9 years. The Gait Profile Score (GPS) was used as primary outcome measure. RESULTS The GPS improved significantly from 13.8° before surgery to 11.2° at short-term (p = 0.007) and to 11.3° at long-term follow-up (p = 0.002). Mean GPS showed a slight deterioration between E1 and E2 due to a minority of six patients (30%) who showed a significant loss of correction. CONCLUSION Surgical treatment in adults with BSCP was feasible and effective in the long-term. Significant improvement of gait and function was maintained in the majority of patients, while some patients were prone to develop crouch gait, hip flexion contractures, or pain.

Abstract
Socially assistive robots (SARs) offer great promise for improving outcomes in paediatric rehabilitation. However, the design of software and interactive capabilities for SARs must be carefully considered in the context of their intended clinical use. While previous work has explored specific roles and functionalities to support paediatric rehabilitation, few have considered the design of such capabilities in the context of ongoing clinical deployment. In this article, we present a two-phase
in situ design
process for SARs in health care, emphasising stakeholder engagement and on-site development. We explore this in the context of developing the humanoid social robot NAO as a socially assistive rehabilitation aid for children with cerebral palsy. We present and evaluate our design process, outcomes achieved, and preliminary results from ongoing clinical testing with 9 patients and 5 therapists over 14 sessions. We argue that our in situ design methodology has been central to the rapid and successful deployment of our system.

Abstract
AIM To explore the evolution of self-care and functional mobility after multilevel surgery in children and adolescents with spastic diplegic cerebral palsy and to identify factors affecting these outcomes. METHOD Thirty-four participants (22 males, 12 females) were evaluated before surgery, and at 2 months, 6 months, 1 year, 18 months, and 2 years after surgery. Self-care was assessed with the Pediatric Evaluation of Disability Inventory Dutch edition. The Mobility Questionnaire47 (MobQues47) and Functional Mobility Scale (FMS) were used to measure functional mobility. RESULTS All outcomes revealed a significant decrease 2 months after single-event multilevel surgery (SEMLS) (p-value between <0.001 and 0.02) followed by a significant increase at 6 months (p<0.001 and p=0.045). Between 6 months and 1 year, a significant increase was also revealed for Mobques47 (p<0.001), FMS (p≤0.008), and the Pediatric Evaluation of Disability Inventory Functional Skills Scale (PEDI-FSS) (p=0.001). Improvement continued until 18 months for the PEDI-FSS. Initial score, initial muscle strength, Gross Motor Function Classification System level, age, and number of surgical interventions significantly influenced time trends for self-care and/or functional mobility. INTERPRETATION Most preoperative scores are regained at 6 months after SEMLS. Further improvement is seen until 18 months. Participants with a higher functional level before surgery will temporarily lose more than participants with lower initial functional ability, but they also fast regain their function. WHAT THIS PAPER ADDS Self-care and functional mobility decrease significantly in the first months after single-event multilevel surgery (SEMLS). Six months after SEMLS most preoperative scores are regained. Impact of SEMLS is more pronounced for functional mobility than for self-care. Muscle strength and functionality at baseline are important influencing factors on the evolution after SEMLS.

Abstract
PURPOSE To describe self-reported life satisfaction and motor function of young adults with cerebral palsy (CP). METHODS A total of 57 young adults with spastic CP classified as levels I (seven), II (25), III (16), IV (nine) by the Gross Motor Function Classification System, followed from childhood by our CP clinic, returned at a mean age of 27 years two months (SD 3 years 4 months). Self-reported life satisfaction and mobility status were measured by the Pediatric Outcomes Data Collection Instrument (PODCI), Patient-Reported Outcomes Measurement Information System (PROMIS), Functional Mobility Scale (FMS) and a project questionnaire. Surgical history and childhood mobility were confirmed from medical records. RESULTS The Functional Mobility Scale demonstrated limited but stable mobility function from childhood to adulthood. The PROMIS and PODCI revealed limited motor function compared with a non-disabled normative reference (p < 0.05). Descriptive results showed high dependence on transportation, housing and income; although PROMIS subscales revealed satisfaction with social activities. Self-recall of childhood mobility function using the FMS correlated highly (r = 0.8; p < 0.0001) with historical records. CONCLUSION Although functional mobility is limited and community independence is not fully achieved in young adults with CP, these participants maintained childhood levels of mobility function into young adulthood, were satisfied with social roles and had minimal reports of pain.

Abstract
PURPOSE OF REVIEW The review provides an update on the treatment of hypertonia in cerebral palsy, including physical management, pharmacotherapy, neurosurgical, and orthopedic procedures. RECENT FINDINGS Serial casting potentiates the effect of Botulinum neurotoxin A injections for spasticity. Deep brain stimulation, intraventricular baclofen, and ventral and dorsal rhizotomy are emerging tools for the treatment of dystonia and/or mixed tone. The long-term results of selective dorsal rhizotomy and the timing of orthopedic surgery represent recent advances in the surgical management of hypertonia. SUMMARY Management of hypertonia in cerebral palsy targets the functional goals of the patient and caregiver. Treatment options are conceptualized as surgical or nonsurgical, focal or generalized, and reversible or irreversible. The role of pharmacologic therapies is to improve function and mitigate adverse effects. Further investigation, including clinical trials, is required to determine the role of deep brain stimulation, intraventricular baclofen, orthopedic procedures for dystonia, and rhizotomy.
