Constraint-induced movement therapy (CIMT) is a potentially effective intervention for children with hemiplegic cerebral palsy (CP). ⋯ Studies varied widely in type and rigor of design; subject, constraint, and intervention characteristics; and ICF level for outcome measures. One outcome measure at the body functions and structure level and 4 outcome measures at the activity level had large and significant treatment effects (d > or = .80), and these findings were from the most rigorous studies. Evidence from more-rigorous studies demonstrated an increased frequency of use of the upper extremity following CIMT for children with hemiplegic CP. The critical threshold for intensity that constitutes an adequate dose cannot be determined from the available research. Further research should include a priori power calculations, more-rigorous designs and comparisons of different components of CIMT in relation to specific children, and measures of potential impacts on the developing brain.

Comparative Study
Comparison of gluteus medius muscle electromyographic activity during forward and lateral step-up exercises in older adults.
Step-up exercises often are suggested for strengthening the hip abductor muscles and improving balance in older adults. Little is known, however, about whether the forward or lateral version of these exercises is best for activating the hip abductor muscles. ⋯ Step-up exercises are effective in activating the GM muscle, with lateral step-up exercises requiring greater GM muscle activation than forward step-up exercises. Further study is needed to determine whether exercise programs for hip abductor muscle strengthening in older adults should preferentially include lateral over forward step-up exercises.
