The aim of this systematic review was to investigate the task specificity of strength training programs for walking in neurologic rehabilitation. Nine electronic databases were searched from conception to October 2012 for randomized controlled trials that used strength training to improve walking in adult neurologic populations. The search identified 25 randomized controlled trials that investigated the efficacy of strength training to improve walking in people with a variety of neurologic conditions. The results revealed that despite significant strength gains, many studies failed to show a significant improvement in walking capacity. Most studies did not include exercises relating to all three main power events important for walking. Strength testing and strengthening exercises were prioritized for the knee extensors and flexors, despite their relatively minor role in human walking. Strengthening exercises performed in the …
