• 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.



Method• 12 poststroke subjects participated in 24 training sessions (3

sessions/wk for 8 wk).• 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.



Results• Posttraining:– Significantly improved lower-limb muscle strength

and power.– Improved self-selected and fastest comfortable

walking speeds.– No changes in clinical assessments.



Conclusion

• 24 sessions of POWER training:– Appear feasible and well tolerated.– May improve muscular and locomotor function.

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