ABSTRACT

We examined explosive leg extensor power (LEP) and gait in men and women after a stroke using an experimental observational design. A convenience sample of consecutively referred individuals (8 men, 6 women) with chronic stroke mean age ± SD, range, 46.4 ± 8.4, 32 - 57 years, and able to walk for four minutes were recruited. The test re-test reliability and performance of LEP was measured together with walking parameters. LEP (Watts·kg-1) and gait measures during a four-minute walk; temporal-spatial gait parameters (GAITRite®) and oxygen cost of walking (mL·kg-1·m-1) were recorded. Percentage Asymmetry LEP (stronger LEP - weaker LEP/stronger LEP x 100) was calculated for each person. LEP was reliable from test to re-test ICC [3, 1] 0.8 - 0.7 (n = 9). Greater Asymmetry LEP correlated strongly with reduced walking velocity, cadence, stance time, and swing time on the weaker leg (n = 14) (p < 0.01). Findings demonstrate explosive LEP, in particular Percentage Asymmetry LEP, can be measured after stroke and is both reliable and related to walking performance. LEP training of the stronger or weaker leg warrants further investigation in this group.

Key words: Stroke, leg extensor power, walking, asymmetry


           Key Points
  • Explosive leg power (LEP) is a reliable measure in individuals recovering from a stroke.
  • Significant asymmetry occurred in LEP in this group.
  • Greater LEP asymmetry related to reduced walking performance after stroke.
