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
neurologic population are not specific to the main muscle groups responsible for
the power generation required for walking. There is a predisposition for strength
testing and strengthening exercises to focus on the knee flexors and extensors
despite their relatively minor role during walking. Further consideration of the
specificity of strength training may provide greater translation of strength
gains to improved walking outcomes.
