Constraint-induced movement therapy for children with neonatal brachial plexus palsy: a randomized crossover trial.

AIM: To determine if constraint-induced movement therapy (CIMT) is more effective than standard care in improving upper-limb activity outcomes in children with neonatal brachial plexus palsy (NBPP). METHOD: Twenty-one children with NBPP (mean age 25mo, SD=10.3, range=17-48mo; 11 males, 10 females) were enrolled in a crossover trial and randomly allocated to first receive CIMT or standard care, each for 8 weeks. The intervention arm consisted of 3 weeks of casting the unaffected limb followed by 5 weeks of transference activities. The Assisting Hand Assessment (AHA) was used to measure bimanual activity performance at baseline, 8 weeks, and 16 weeks, scored by blinded raters. The Pediatric Motor Activity Log-Revised (PMAL-R) was used as a caregiver-reported secondary outcome measure. RESULTS: After concealed random allocation (n=21), there were no significant differences on demographics or baseline measures. CIMT was superior compared to control in terms of bimanual activity performance with a mean difference in AHA change score of 4.8 (SD=10.5, p=0.04, Cohen's δ=0.46). There were no significant differences between treatment conditions on the PMAL-R. INTERPRETATION: CIMT is favored over standard care for bimanual activity performance. Future research should investigate a longer follow-up period, additional comparator interventions, and analyse differences by participant characteristics. WHAT THIS PAPER ADDS: Gains in bimanual activity performance were greater after constraint-induced movement therapy (CIMT) compared to no CIMT. Frequency and quality of movement were not significantly different between treatment groups.

Recommendations for Therapy following Nerve Transfer for Children with Acute Flaccid Myelitis.

AIM: To provide recommendations for pre- and post-operative occupational and physical therapy for children with acute flaccid myelitis (AFM). METHODS: Writing panel members consisted of an interdisciplinary team of seven healthcare professionals specializing in the care of children with AFM. The panel reviewed background material on AFM, nerve transfer, and rehabilitation principles applied to pediatrics. Recommendations were prioritized if evidence was available. Where there was no known evidence to support a recommendation, this was noted. RECOMMENDATIONS: Communication and coordination among interprofessional team members are vital to a comprehensive family-centered rehabilitation program. Surgical planning should include team preparation accounting for frequency, duration, and timing of treatment, as well as individual characteristics and developmental status of the child. Recommendations for pre-operative and six phases of post-operative therapy address assessment, strengthening, range of motion, orthoses, performance of functional activity, and support of the family. CONCLUSION: Rehabilitation following nerve transfer in children with AFM requires interdisciplinary collaboration and a multisystem approach to assessment and treatment. As new evidence becomes available, recommendations may be revised or replaced accordingly.

Therapeutic application of electrical stimulation and constraint induced movement therapy in perinatal brachial plexus injury: A case report.

Infants and children with perinatal brachial plexus injury (PBPI) have motion limitations in the shoulder, elbow, forearm and hand that are dependent on the level of injury and degree of recovery. The injury and subsequent recovery period occur during critical periods of central and spinal neural development placing infants and children at-risk for developmental disregard and disuse of the affected arm and hand. A case report outlines the therapy and surgical interventions provided in the first 2 years of life for a child with global PBPI and a positive Horner's sign. Electrical stimulation and constraint induced movement therapy provided sequentially were effective therapy interventions. Neurosurgery to repair the brachial plexus was performed at an optimal time period.(2) The Assisting Hand Assessment,(12) Modified Mallet(13) and Active Movement Scale(14) are effective outcome measures in PBPI and served as valuable guides for therapy intervention.

Long term functional outcomes after early childhood pollicization.

STUDY DESIGN: Retrospective Cohort INTRODUCTION: Important outcomes of polliciation to treat thumb hypoplasia/aplasia include strength, function, dexterity, and quality of life. PURPOSE OF THE STUDY: To evaluate outcomes and examine predictors of outcome after early childhood pollicization. METHODS: 8 children (10 hands) were evaluated 3-15 years after surgery. Physical examination, questionnaires, grip and pinch strength, Box and Blocks, 9-hole pegboard, and strength-dexterity (S-D) tests were performed. RESULTS: Pollicized hands had poor strength and performance on functional tests. Six of 10 pollicized hands had normal dexterity scores but less stability in maintaining a steady-state force. Predictors of poorer outcomes included older age at surgery, reduced metacarpophalangeal and interphalangeal range of motion, and radial absence. DISCUSSION: Pollicization resulted in poor strength and overall function, but normal dexterity was often achieved using altered control strategies. CONCLUSIONS: Most children should obtain adequate dexterity despite weakness after pollicization except older or severely involved children. LEVEL OF EVIDENCE: IV.

Quantitative assessment of dynamic control of fingertip forces after pollicization.

Dexterity after finger pollicization (reconstruction to thumb) is critical to functional outcomes. While most tests of hand function evaluate a combination of strength, coordination, and motor control, the Strength-Dexterity (S-D) paradigm focuses on the dynamic control of fingertip forces. We evaluated 10 pollicized and 5 non-pollicized hands from 8 participants ages 4-17 years (2 female, 6 male; 10.6 ± 4.5 years). Participants partially compressed and held an instrumented spring prone to buckling between the thumb and first finger to quantify dynamic control over the direction and magnitude of fingertip forces. They also completed traditional functional tests including grip, lateral pinch, and tripod pinch strength, Box and Blocks, and 9-hole peg test. Six of 10 pollicized hands and all non-pollicized hands had S-D scores comparable to typically developing children. However, dynamical analysis showed that pollicized hands exhibit greater variability in compression force, indicating poorer corrective action. Almost all pollicized hands scored below the normal range for the traditional functional tests. The S-D test Z-scores correlated moderately with Z-scores from the other functional tests (r = 0.54-0.61; p = 0.02-0.04) but more weakly than amongst the other functional measures (r = 0.58-0.83; p = 0.0002-0.02), suggesting that the S-D test captures a different domain of function. A higher incidence of radial absence in the hands with poor S-D scores (3/4 vs. 0/6 in hands with normal S-D scores, p = 0.03) was the only clinical characteristic associated with S-D outcome. Overall, these results suggest that while most pollicized hands can control fingertip forces, the nature of that control is altered.
