effects of task-specific locomotor and strength training in adults who were ambulatory after stroke:...
DESCRIPTION
A phase II, single-blinded, randomized clinical trial was conducted to determine the effects of combined task-specific and lower-extremity (LE) strength training to improve walking ability after stroke.TRANSCRIPT

The participants were 80 adults who were ambulatory 4 months to 5 years after a
unilateral stroke.

Exercise sessions were 4 times per week for 6 weeks
Outcomes were self-selected walking speed, fast walking speed, and 6-minute walk distance measured before and after intervention and at a 6-month follow-up.
