Feasibility of lower- limb muscle power training to enhance locomotor function poststroke. J Rehabil Res Dev. 2015;52(1):77–84. http://dx.doi.org/10.1682/JRRD.2014.04.0109 Slideshow Project DOI:10.1682/JRRD.2014.04.0109JSP Aim – Examine feasibility and effects of Poststroke Optimization of Walking using Explosive Resistance (POWER) training. Relevance – Poststroke motor control is characterized by greatly reduced muscle power generation. – Extent to which muscle power limits walking performance or should be prioritized in rehabilitation is unknown.

Feasibility of lower- limb muscle power training to enhance locomotor function poststroke.

Exercises (performed at high concentric velocity): – Leg press. – Calf raises. – Jump training. Measures at pretraining, posttraining, and 8 wk later: – Self-selected and fastest comfortable walking speeds. – Knee extensor and plantar flexor strength and power. Clinical assessments commonly used in poststroke rehabilitation trials.

Future studies should determine efficacy of POWER compared with established approaches to improve poststroke motor control.
