Background Comparisons between various conservative managements of spastic equinus deformity in cerebral palsy demonstrated limited evidences, to evaluate the efficacy of conservative treatment among cerebral palsy children with spastic equinus foot regarding gait and ankle motion. Methods Studies were identified from PubMed and Scopus up to February 2022. Inclusion criteria were randomized controlled trial (RCT), conducted in spastic cerebral palsy children with equinus deformity, aged less than 18 years, compared any conservative treatments (Botulinum toxin A; BoNT-A, casting, physical therapy, and orthosis), and evaluated gait improvement (Physician Rating Scale or Video Gait Analysis), Observational Gait Scale, Clinical Gait Assessment Score, ankle dorsiflexion (ankle dorsiflexion at initial contact, and passive ankle dorsiflexion), or Gross Motor Function Measure. Any study with the participants who recently underwent surgery or received BoNT-A or insufficient data was excluded. Two authors were independently selected and extracted data. Risk of bias was assessed using a revised Cochrane risk-of-bias tool for randomized trials. I2 was performed to evaluate heterogeneity. Risk ratio (RR), the unstandardized mean difference (USMD), and the standardized mean difference were used to estimate treatment effects with 95% confidence interval (CI). Results From 20 included studies (716 children), 15 RCTs were eligible for meta-analysis (35% had low risk of bias). BoNT-A had higher number of gait improvements than placebo (RR 2.64, 95% CI 1.71, 4.07, I2 = 0). Its combination with physical therapy yielded better passive ankle dorsiflexion at knee extension than physical therapy alone (USMD = 4.16 degrees; 95% CI 1.54, 6.78, I2 = 36%). Casting with or without BoNT-A had no different gait improvement and ankle dorsiflexion at knee extension when compared to BoNT-A. Orthosis significantly increased ankle dorsiflexion at initial contact comparing to control (USMD 10.22 degrees, 95 CI% 5.13, 15.31, I2 = 87%). Conclusion BoNT-A and casting contribute to gait improvement and ankle dorsiflexion at knee extension. BoNT-A specifically provided gait improvement over the placebo and additive effect to physical therapy for passive ankle dorsiflexion. Orthosis would be useful for ankle dorsiflexion at initial contact. Trial registration PROSPERO number CRD42019146373.
ObjectiveThis study was aimed to establish the reference values of ankle kinematics and factors associated with ankle kinematics of healthy Thai adults.MethodsA prospective cohort was conducted among healthy volunteers aged between 18 and 40 years and evaluated gait analysis between 2016 and 2020. After applying the modified Halen Hayes marker set, participants were assigned to walk 8–10 rounds with their preferred speed. Demographic data i.e., age, gender and body mass index (BMI) and ankle kinematics (varus-valgus, dorsiflexion-plantar flexion, foot progression, and ankle rotation) using motion analysis software were recorded and analyzed.Results98 volunteers (60 females and 38 males) aged 28.6 ± 5.4 years with body mass index 21.2 ± 2.0 kg/m2 were included. The average ranges of ankle kinematics entire gait cycle were varus-valgus −1.62 to 3.17 degrees, dorsiflexion-plantar flexion 0.67 to 14.52 degrees, foot progression −21.73 to −8.47 degrees, and ankle rotation 5.22 to 9.74 degrees. The ankle kinematic data in this study population was significantly different from the normal values supplied by OrthoTrak software of the motion analysis program, especially more ankle internal rotation at mid-stance (5.22 vs. −12.10 degrees) and terminal stance (5.48 vs. −10.74 degrees) with P < 0.001. Foot progression significantly exhibited more external rotation for 1.5 degrees on the right compared to the left side, and for 5 degrees more in males than females. One increment in age was significantly correlated with ankle internal rotation at mid-swing (coefficient 0.21 degrees, P = 0.039). BMI had no statistical association with ankle kinematics. Statistical parametric mapping for full-time series of angle assessments showed significantly different foot progression at initial contact and terminal stance between sides, and our ankle kinematics significantly differed from the reference values of the motion analysis program in all planes (P < 0.05).ConclusionThe reference of ankle kinematics of Thai adults was established and differences between sides and the normal values of the motion analysis program were identified. Advanced age was associated with ankle internal rotation, and male gender was related to external foot progression. Further studies are needed to define all-age group reference values.
Background Recent pieces of evidence about the efficacy of gait rehabilitation for incomplete spinal cord injury remain unclear. We aimed to estimate the treatment effect and find the best gait rehabilitation to regain velocity, distance, and Walking Index Spinal Cord Injury (WISCI) among incomplete spinal cord injury patients. Method PubMed and Scopus databases were searched from inception to October 2022. Randomized controlled trials (RCTs) were included in comparison with any of the following: conventional physical therapy, treadmill, functional electrical stimulation and robotic-assisted gait training, and reported at least one outcome. Two reviewers independently selected the studies and extracted the data. Meta-analysis was performed using random-effects or fixed-effect model according to the heterogeneity. Network meta-analysis (NMA) was indirectly compared with all interventions and reported as pooled unstandardized mean difference (USMD) and 95% confidence interval (CI). Surface under the cumulative ranking curve (SUCRA) was calculated to identify the best intervention. Results We included 17 RCTs (709 participants) with the mean age of 43.9 years. Acute-phase robotic-assisted gait training significantly improved the velocity (USMD 0.1 m/s, 95% CI 0.05, 0.14), distance (USMD 64.75 m, 95% CI 27.24, 102.27), and WISCI (USMD 3.28, 95% CI 0.12, 6.45) compared to conventional physical therapy. In NMA, functional electrical stimulation had the highest probability of being the best intervention for velocity (66.6%, SUCRA 82.1) and distance (39.7%, SUCRA 67.4), followed by treadmill, functional electrical stimulation plus treadmill, robotic-assisted gait training, and conventional physical therapy, respectively. Conclusion Functional electrical stimulation seems to be the best treatment to improve walking velocity and distance for incomplete spinal cord injury patients. However, a large-scale RCT is required to study the adverse events of these interventions. Trial registration: PROSPERO number CRD42019145797.
