The combined effect of Dynamic splinting and Neuromuscular electrical stimulation in reducing wrist and elbow contractures in six children with Cerebral palsy

Neuromuscular Electrical Stimulation of Upper Limbs in Patients With Cerebral Palsy: A Systematic Review and Meta-analysis of Randomized Controlled Trials

OBJECTIVE

The aim of the study is to assess the effects of neuromuscular electrical stimulation on the upper limbs of patients with cerebral palsy.

DESIGN

We searched PubMed, Cochrane, Embase, and Scopus databases for randomized controlled trials examining the effects of neuromuscular electrical stimulation on the upper limbs of children with cerebral palsy.

RESULTS

Eight randomized controlled trials ( N = 294) were included in the meta-analysis. Compared with traditional physical therapy, sensorimotor training and task-oriented training, constraint-induced movement therapy, dynamic bracing, and conventional robot-assisted therapy, neuromuscular electrical stimulation in combination with these therapies resulted in significantly greater functional scale scores (standardized mean difference = 0.80; 95% confidence interval = 0.54 to 1.06), muscle strength of upper limbs (standardized mean difference = 0.57; 95% confidence interval = 0.25 to 0.88), and spasticity of upper limbs (relative risk = 2.53; 95% confidence interval = 1.46 to 4.39; standardized mean difference = -0.18; 95% confidence interval = -0.29 to -0.06) but did not improve the wrist range of motion (standardized mean difference = 0.43; 95% confidence interval = -0.04 to 0.91). In addition, the effect of neuromuscular electrical stimulation on functional scale scores remained after 3-mo follow-up (standardized mean difference = 0.68; 95% confidence interval = 0.16 to 1.2).

CONCLUSIONS

Neuromuscular electrical stimulation effectively improved hand function, muscle strength, and spasticity in patients with cerebral palsy.

Perinatal stroke: mapping and modulating developmental plasticity

Most cases of hemiparetic cerebral palsy are caused by perinatal stroke, resulting in lifelong disability for millions of people. However, our understanding of how the motor system develops following such early unilateral brain injury is increasing. Tools such as neuroimaging and brain stimulation are generating informed maps of the unique motor networks that emerge following perinatal stroke. As a focal injury of defined timing in an otherwise healthy brain, perinatal stroke represents an ideal human model of developmental plasticity. Here, we provide an introduction to perinatal stroke epidemiology and outcomes, before reviewing models of developmental plasticity after perinatal stroke. We then examine existing therapeutic approaches, including constraint, bimanual and other occupational therapies, and their potential synergy with non-invasive neurostimulation. We end by discussing the promise of exciting new therapies, including novel neurostimulation, brain-computer interfaces and robotics, all focused on improving outcomes after perinatal stroke.

Dynamic Splinting in Children and Adolescents With Stiffness After Knee Surgery

PURPOSE

The purpose of this study was to investigate the indications and outcomes of dynamic splinting (DS) of the arthrofibrotic knee in the pediatric population.

METHODS

Seventy-four patients (41 males, 33 females) with postoperative arthrofibrosis treated with DS after an index knee surgery were reviewed. Median age was 13 years (range, 4 to 18 y), and median follow-up was 17 months (interquartile range, 10 to 28 mo). Demographics, index surgery procedure, preoperative and postoperative knee range of motion (ROM) measurements, treatment length and subsequent need for manipulation under anesthesia (MUA), and surgical lysis of adhesions (LOA) were evaluated. A ROM deficit was defined as lack of extension ≥10 degrees or lack of flexion <130 degrees. Successful improvement of ROM was defined as an increase of ≥10 degrees in flexion, extension, or both. There were 23 patients with flexion deficit only, 17 with extension deficit only, and 34 with combined flexion and extension deficits. Wilcoxon signed-rank test was used to assess median improvement in ROM. Patients were classified into 4 surgical groups: anterior cruciate ligament (ACL) reconstruction without meniscal repair (n=19), ACL reconstruction with meniscal repair (n=12), tibial spine fracture repair (n=21), and other (n=22). Multivariable logistic regression was used to identify independent predictors of failure of DS requiring MUA and LOA.

RESULTS

A total of 57 patients with flexion deficits showed median improvement of 30 degrees in flexion (95% confidence interval, 0-90 degrees; P<0.001), and 51 patients with extension deficits showed median improvement of 7 degrees in extension (95% confidence interval, 0-60 degrees; P<0.001). DS was associated with ROM improvement in 84% and avoided the need for surgery in 58% of all 74 patients included in the study. Multivariate analysis of the ACL with meniscus repair subgroup revealed that each 1-month delay in DS treatment was associated with a 5-fold increased risk of undergoing a LOA (P=0.007). Thirty-six (63%) patients with flexion deficit avoided need for surgery, whereas 26 (51%) patients with extension deficits avoided surgery.

CONCLUSIONS

Our data suggest that DS is an effective method to increase knee ROM and reduce the need for subsequent MUA/LOA in the pediatric and adolescent patient with arthrofibrosis after an index knee surgery.

Rationale for prescription, and effectiveness of, upper limb orthotic intervention for children with cerebral palsy: a systematic review

PURPOSE

To explore (i) reasons for upper limb orthosis prescription for children with cerebral palsy (CP), (ii) the link between reason and effect according to intended outcome and outcome measure utilized and (iii) to classify the prescribed orthoses using standard terminology.

METHOD

A prospectively registered (center for reviews and dissemination: 42015022067) systematic review searched for experimental and observational studies investigating rigid/thermoplastic upper limb orthotic intervention for children aged 0-18 with CP. The Cochrane central register, MEDLINE, CINAHL, Embase, SCOPUS and Web of Science databases were searched. Included studies were assessed for risk of bias.

RESULTS

Sixteen studies met selection criteria. Two studies described a specific reason for orthosis prescription, six prescribed orthoses to manage a clinical symptom and eight did not describe a reason. Eight studies were analyzed for effect according to intended outcome with no clear connection found between reasons for prescription, outcome measures utilized and effect reported.

INTERPRETATION

The lack of evidence for upper limb orthotic intervention for children with CP leads to uncertainty when considering this treatment modality. Future research is needed to evaluate the effect of orthosis wear in relation to intended outcome utilizing robust methods and valid and reliable outcome measures. Implications for rehabilitation: Insufficient evidence exists about the reason for prescription of upper limb orthoses. The connection between reason for orthosis prescription, intended outcome, outcome measure utilized and observed effect is unclear. Recommend orthosis prescription to be accompanied by clear documentation of the aim of the orthosis and description using orthosis classification system terminology. Outcome measures consistent with the reason for orthosis prescription and intended outcome of the intervention are essential to measure effectiveness of the intervention.

Portuguese cultural adaptation and validation of the Activities Scale for Kids (ASK)

OBJECTIVES

The main purpose of the current study was to perform the cross cultural adaptation and validation of the Activities Scale for Kids (ASK) both in its capability and performance versions to the European Portuguese language so it can be used in Portugal by healthcare professionals in children from 5 to 15 years of age with functional disabilities related to specific health conditions.

METHODS

The cross-cultural adaptation of ASK followed the classic sequential methodology for linguistic equivalence. To test its validity, internal consistency, and reproducibility, the Portuguese version of ASK was administered together with the KINDL Questionnaire (KINDL) to 88 children (10±3 years of age) with functional limitations. The test-retest study was conducted two weeks apart.

RESULTS

After obtaining the semantic and content validity, the Portuguese version of ASK demonstrated good levels of reproducibility (performance: intraclass correlation coefficient [ICC]=0.99; capability: ICC=0.98) and internal consistency (performance: α=0.98; capability: α=0.97). The correlations between ASK and KINDL were positive and moderate.

CONCLUSIONS

The Portuguese version of ASK showed acceptable levels of validity, internal consistency, and reproducibility; the authors recommend its use in clinical settings.

Effects of neuromuscular electrical stimulation on the wrist and finger flexor spasticity and hand functions in cerebral palsy

PURPOSE

To evaluate the effects of neuromuscular electrical stimulation on wrist range of motion, wrist and finger flexor spasticity, and hand functions in patients with unilateral cerebral palsy.

METHOD

Twenty-four children with unilateral spastic cerebral palsy (14 boys and 10 girls) between the ages of 5 and 14 years were randomized into neuromuscular electrical stimulation and control groups. Conventional exercises were applied, and static volar wrist-hand orthosis was administered to all patients 5 days a week for 6 weeks. Additionally, 30-minute neuromuscular electrical stimulation sessions were applied to the wrist extensor muscles in the neuromuscular electrical stimulation group. Patients were evaluated by Zancolli Classification System, Manual Ability Classification System, and Abilhand-Kids Test.

RESULTS

Compared with baseline, a significant increase was evident in active wrist extension angle at the fourth and sixth weeks in both groups (all P < 0.001), more prominent in the neuromuscular electrical stimulation group at the fourth and sixth weeks (P = 0.015 and P = 0.006, respectively). A decrease was observed in the spasticity values in the neuromuscular electrical stimulation group at the fourth and sixth weeks (P = 0.002 and P = 0.001, respectively) and in the control group only at the sixth week (P = 0.008). Abilhand-Kids values improved only in the neuromuscular electrical stimulation group (P < 0.001).

CONCLUSION

Neuromuscular electrical stimulation application in addition to conventional treatments is effective in improving active wrist range of motion, spasticity, and hand functions in cerebral palsy.

Valid and reliable instruments for arm-hand assessment at ICF activity level in persons with hemiplegia: a systematic review

BACKGROUND

Loss of arm-hand performance due to a hemiparesis as a result of stroke or cerebral palsy (CP), leads to large problems in daily life of these patients. Assessment of arm-hand performance is important in both clinical practice and research. To gain more insight in e.g. effectiveness of common therapies for different patient populations with similar clinical characteristics, consensus regarding the choice and use of outcome measures is paramount. To guide this choice, an overview of available instruments is necessary. The aim of this systematic review is to identify, evaluate and categorize instruments, reported to be valid and reliable, assessing arm-hand performance at the ICF activity level in patients with stroke or cerebral palsy.

METHODS

A systematic literature search was performed to identify articles containing instruments assessing arm-hand skilled performance in patients with stroke or cerebral palsy. Instruments were identified and divided into the categories capacity, perceived performance and actual performance. A second search was performed to obtain information on their content and psychometrics.

RESULTS

Regarding capacity, perceived performance and actual performance, 18, 9 and 3 instruments were included respectively. Only 3 of all included instruments were used and tested in both patient populations. The content of the instruments differed widely regarding the ICF levels measured, assessment of the amount of use versus the quality of use, the inclusion of unimanual and/or bimanual tasks and the inclusion of basic and/or extended tasks.

CONCLUSIONS

Although many instruments assess capacity and perceived performance, a dearth exists of instruments assessing actual performance. In addition, instruments appropriate for more than one patient population are sparse. For actual performance, new instruments have to be developed, with specific focus on the usability in different patient populations and the assessment of quality of use as well as amount of use. Also, consensus about the choice and use of instruments within and across populations is needed.
