Randomized Controlled Trial
Motor control exercise for chronic low back pain: a randomized placebo-controlled trial.
The evidence that exercise intervention is effective for treatment of chronic low back pain comes from trials that are not placebo-controlled. ⋯ Motor control exercise produced short-term improvements in global impression of recovery and activity, but not pain, for people with chronic low back pain. Most of the effects observed in the short term were maintained at the 6- and 12-month follow-ups.

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.

Knee joint arthritis causes pain, decreased range of motion, and mobility limitation. Knee replacement reduces pain effectively. However, people with knee replacement have decreases in muscle strength ("force-generating capacity") of the involved leg and difficulties with walking and other physical activities. ⋯ Deficits in muscle torque and power and in the extensor muscle CSA were present 10 months after knee replacement, potentially causing limitations in negotiating stairs. To prevent mobility limitations and disability, deficits in lower-limb power should be considered during rehabilitation after knee replacement.

Self-report measures for assessing specific fear of activities have not been reported in the peer-reviewed literature, but are necessary to adequately test treatment hypotheses related to fear-avoidance models. ⋯ The FDAQ is a potentially viable measure for fear of specific activities in physical therapy settings. These analyses suggest the FDAQ may be appropriate for determining graded exposure treatment plans and monitoring changes in fear levels, but is not appropriate as a screening tool.
