Clin Biomech (Bristol, Avon) 2020; 71:11-23. [PMID: 31677546 DOI: 10.1016/j.clinbiomech.2019.09.005] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/19/2019] [Revised: 07/19/2019] [Accepted: 09/08/2019] [Indexed: 02/07/2023]
Abstract
BACKGROUND Studies have demonstrated that ambulatory children and adolescents with cerebral palsy demonstrate atypical gait patterns. Out of numerous gait variables, identification of the most deteriorated gait parameters is important for targeted and effective gait rehabilitation. Therefore, this study aimed to identify the gait parameters with the most discriminating nature to distinguish cerebral palsy gait from normal gait. METHODS Multiple databases were searched to include studies on ambulatory children and adolescents with cerebral palsy that included gait (spatio-temporal, kinematic, and kinetic) and dynamic stability variables. FINDINGS Of 68 studies that met the inclusion criteria, 35 studies were included in the meta analysis. Effect size was used to assess the discriminative strength of each variable. A large effect (≥ 0.8) of cerebral palsy on double limb support time (Standardized Mean Difference = 0.98), step length (Standardized Mean Difference = 1.65), step width (Standardized Mean Difference = 1.21), stride length (Standardized Mean Difference = 1.75), and velocity (Standardized Mean Difference = 1.42) was observed at preferred-walking speed. At fast-walking speed, some gait variables (i.e. velocity and stride length) exhibited larger effect size compared to preferred-walking speed. For some kinematic variables (e.g. range of motion of pelvis), the effect size varied across the body planes. INTERPRETATION Our systematic review detects the most discriminative features of cerebral palsy gait. Non-uniform effects on joint kinematics across the anatomical planes support the importance of 3D gait analysis. Differential effects at fast versus preferred speeds emphasize the importance of measuring gait at a range of speeds.

Abstract
Selective dorsal rhizotomy at the lumbar level is a neurosurgical procedure, which reduces spasticity in the legs. Its effect has mainly been studied in children with spastic cerebral palsy. Little is known about the outcome of selective dorsal rhizotomy in patients with neurodegenerative disorders. We report the clinical course after selective dorsal rhizotomy in 2 patients with progressive spasticity. Leg spasticity was effectively and persistently reduced in both patients, facilitating care and improving sitting comfort. However, spasticity of the arms and other motor disturbances, such as spontaneous extension spasms and the ataxia, increased gradually in time. Selective dorsal rhizotomy leads to a disappearance of leg spasticity in patients with a neurodegenerative disease. Other motor signs are not influenced and may increase due to the progressive nature of the underlying disease.

Abstract
RATIONALE Selective dorsal rhizotomy (SDR) is a surgical technique developed over the past decades to manage patients diagnosed with cerebral palsy suffering from spastic diplegia. It involves selectively lesioning sensory rootlets in an effort to maintain a balance between elimination of spasticity and preservation of function. Several recent long-term outcome studies have been published. In addition, shorter follow-up randomized controlled studies have compared the outcome of patients having undergone physiotherapy alone with those that received physiotherapy after selective dorsal rhizotomy. MATERIALS AND METHODS In this account, we will discuss the rationale and outcome after SDR. The outcome is addressed in terms of the gross motor function measurement scale (GMFM), degree of elimination of spasticity, strength enhancement, range of motion, fine motor skills, activity of daily living, spastic hip, necessity for postoperative orthopedic procedures, bladder and sphincteric function, and finally possible early or late complications associated with the procedure. CONCLUSION We conclude that SDR is a safe procedure, which offers durable and significant functional gains to properly selected children with spasticity related to cerebral palsy.

Abstract
OBJECTIVES The purpose of the study was to determine if there are preoperative clinical characteristics that might be predictive of a poor outcome after selective dorsal rhizotomy (SDR) surgery in children with spastic cerebral palsy (CP). METHODS A retrospective analysis was performed on 174 children who had undergone SDR from 1983 to 2001. Patients were divided into two groups according to their outcome at approximately 1 year after surgery: "acceptable" or "poor" outcome. As predictors of outcome, the factors compared were age at operation, types of CP (diplegia, quadriplegia), history of prematurity, prior lower limb orthopedic surgeries, history of seizures, dystonic limbs, opisthotonic posturing, lumbar hyperlordosis, truncal hypotonia, preoperative ambulatory function, preoperative Gross Motor Function Classification System (GMFCS) scores, and presence of intellectual delay and speech delay. RESULTS Eleven children (6.3%) had a "poor" outcome. The type of CP (P<0.001) and intellectual delay (P=0.015) were significant predictors of outcome in the univariate regression analysis, but only the type of CP retained significant predictive power in the multivariate analysis. CONCLUSION These data suggest that preoperative diagnosis is the strongest predictor of outcome after SDR. Intellectual delay demonstrated predictive power only in the univariate model, suggesting that it might have some prognostic value but less than the diagnosis.

Abstract
OBJECTIVE To compare the treatment effectiveness of botulinum toxin type A (BTX-A) and phenol blocks in managing lower limb spasticity and gait dysfunction in children with cerebral palsy. DESIGN This is a case-controlled study that took place in a tertiary center's gait laboratory. A total of 27 ambulatory children with cerebral palsy spastic diplegia, aged from 3 to 7 yrs, and 20 normal children were recruited into this study. Sixteen children with cerebral palsy received BTX-A injections, and 11 received phenol motor point blocks. Gait analyses were assessed by a portable computer-assisted system (Computer DynoGraphy, Infotronic, The Netherlands). Both the BTX-A and phenol groups received gait analysis at 1 wk before and 2 mos after injection treatments. RESULTS Significant improvements in gait variables of velocity and cadence were noted in children with cerebral palsy after BTX-A injections as compared with the phenol block group. Gaitline and cyclogram patterns also improved significantly in the BTX-A group. The adverse clinical effects of BTX-A injections were less severe as compared with phenol injections. CONCLUSIONS BTX-A injections demonstrated superior treatment effects in improving gait variables and patterns in children with spastic diplegia as compared with phenol blocks. BTX-A injections also revealed fewer clinical side effects and were well tolerated by children with cerebral palsies.

Abstract
This study was conducted to determine whether an objective and quantitative measure for active ankle range of motion would be sensitive to differences between persons of able body and those with cerebral palsy (CP), and between pre- and postselective dorsal rhizotomy (SDR). Twelve children with spastic diplegia CP were tested before undergoing an SDR, and again after 8 months of intensive physical therapy (SDR group). Fourteen other children with spastic diplegia were tested initially and again 8 months following no intervention but maintaining their existing level of physical therapy (CP group). Twenty age-matched children of able body were tested once (AB group). A video system recorded active sagittal plane ankle movements as the seated child independently performed maximum dorsiflexion and plantarflexion. The data were tracked and analyzed to determine end-range dorsiflexion and plantarflexion, and total active ankle range of motion. Repeated-measures ANOVA and Tukey post hoc tests were used to test for significant differences among and between groups, p < 0. 05. Results for the SDR group indicated a significant increase in end-range dorsiflexion and total range of motion following the surgery, with no changes in any measures for the CP group. Results for both groups with CP indicated differences vs. the AB group. The measure provided additional information from what has previously been reported for active ankle range of motion. The integration of this measure with other objective measures for quantifying impairments and presurgical function may be useful in predicting post-SDR gait status and other functional activities.

Abstract
OBJECTIVE We investigated the correlation between movement patterns, measured by polyelectromyography (PEMG), and clinical motor manifestations in children with cerebral palsy. DESIGN Subjects included 53 children with spastic cerebral palsy (diplegic [n = 43] and quadriplegic [n = 10] groups) and 18 normal children. All children underwent PEMG assessments, recorded from pairs of flexor/extensor muscles during voluntary movement. We correlated PEMG patterns with clinical motor assessments, including muscle tone, range of motion, and ambulatory and functional capacities in the children with cerebral palsy. RESULTS Children with cerebral palsy exhibited four distinct PEMG patterns, ranging from partial reciprocal to complete synchrony. Lower PEMG pattern scores were significantly associated with better ambulatory (rho = 0.88, P < 0.01) and functional (rho = 0.78, P < 0.01) capacities. PEMG patterns also had weakly positive relationships with muscle tone (rho > 0.33, P < 0.01) and range of motion of both lower limbs (rho > 0.31, P < 0.01). Most children of spastic diplegia with PEMG patterns II and III had independent ambulatory capacities and mild limitation of functional capacity, whereas most children with pattern of IV and V had no ambulatory abilities and no independent functional capacities (P < 0.01). CONCLUSIONS These findings suggest that PEMG patterns correlate with clinical motor deficits and may allow us to plan treatment strategies based on underlying motor control in cerebral palsy.

Abstract
Object. Selective posterior rhizotomy (SPR) may result in considerable benefit for children with spastic cerebral palsy. To date, however, there have been few studies in which validated functional outcome measures have been used to report surgical results beyond 3 years. The authors analyzed data obtained from the McGill Rhizotomy Database to determine long-term functional performance outcomes in patients who underwent lumbosacral dorsal rhizotomy performed using intraoperative electrophysiological monitoring.
Methods. The study population was composed of children with debilitating spasticity who underwent SPR and were evaluated by a multidisciplinary team preoperatively and at 6 months and 1 year postoperatively. Quantitative standardized assessments of activities of daily living (ADL) were obtained using the Pediatric Evaluation of Disability Inventory (PEDI). Of 57 patients who met the entry criteria for the study, 41 completed the 3-year assessments and 30 completed the 5-year assessments.
Statistical analysis demonstrated significant improvement in the mobility and self-care domains of the functional skills dimension at 1 year after SPR. The preoperative and 1-, 3-, and 5-year postoperative scaled scores for the mobility domain were 56, 64, 77.2, and 77.8, respectively. The scaled score for the self-care domain increased from 59 presurgery to 67.9, 81.6, and 82.4 at the 1-, 3-, and 5-year postoperative assessments, respectively.
Conclusions. The results of this study support the presence of significant improvements in functional performance, based on PEDI scores obtained 1 year after SPR. The improvements persisted at the 3- and 5-year follow-up examinations. The authors conclude that SPR performed using intraoperative stimulation is valuable in the augmentation of motor function and self-care skills essential to the performance of ADL.

Abstract
OBJECT Selective posterior rhizotomy (SPR) is a well-recognized treatment for children with spastic cerebral palsy (CP). Few investigators have used quantitative outcome measures to assess the surgical results beyond 3 years. The authors analyzed data obtained from the McGill Rhizotomy Database to determine the long-term functional outcome of children who had undergone selective dorsal rhizotomy accompanied by intraoperative electrophysiological monitoring. METHODS The study population was composed of children with spastic CP who underwent SPR and were evaluated by a multidisciplinary team preoperatively, and at 6 months and 1 year postoperatively. Quantitative standardized assessments of lower-limb spasticity, passive range of motion, muscle strength, and ambulatory function were obtained. Of the 93 patients who met the entry criteria for the study, 71 completed the 3-year and 50 completed the 5-year assessments, respectively. Statistical analysis demonstrated significant improvements in spasticity, range of motion, and functional muscle strength at 1 year after SPR. The preoperative, 1-, 3-, and 5-year values for the global score of the Gross Motor Function Measure were 64.6, 70.8, 80, and 85.6, respectively. The greatest improvement occurred in the dimensions reflecting lower-extremity motor function, where the mean change was 10.1% at 1 year, 19.9% at 3 years, and 34.4% at the 5-year follow-up review in comparison with the baseline value. This was associated with a lasting improvement in alignment and postural stability during developmental positions, as well as increased ability to perform difficult transitional movements. CONCLUSIONS The results of this study support the presence of significant improvements in lower-limb functional motor outcome 1 year after SPR, and the improvements persist at 3 and 5 years. The authors conclude that SPR in conjunction with intraoperative stimulation is valuable for permanently alleviating lower-limb spasticity while augmenting motor function.

Abstract
Management of children with cerebral palsy (CP) is the focus of considerable resources in many countries, so that evaluation of the efficacy for new and established treatments is imperative. Botulinum toxin type A (BTX-A) is a relatively new method of spasticity management in children with cerebral palsy. It has been the focus of extensive research since its application to cerebral palsy 10 years ago. In a systematic review relating to the management of the lower limb in cerebral palsy 156 papers were identified. These were categorized according to Sackett and the World Health Organisation International Classification of Impairments, Disabilities and Handicaps model. We identified 10 randomized trials evaluating the use of BTX-A in the lower limb in children with cerebral palsy in a systematic review. A meta-analysis showed the pooled risk difference between BTX-A and placebo in three trials was 0.25 (95% CI 0.13, 0.37) and 0.23 (95% CI -0.06, 0.53) for two trials of BTX-A and casting using the physicians rating scale. These represent moderate treatment effects that are dosage-dependent. Outcomes were also compared for function in five studies. The type of evidence for BTX-A was graded by each treatment indication and directions for future research were then drawn from the available evidence.
