[Effectiveness of backward walking treadmill training in lower extremity function after stroke]

Abstract

Objective: To examine the effectiveness of backward walking treadmill training for restoration of motor function, balance and walking speed in patients with stroke.

Methods: Twenty-six patients with stroke, 17 males and 9 females, aged 36 - 64, with the lower extremity Brunnstrom motor recovery stage at 3 or 4, able to walk for 10 m without walking aid or orthosis, were randomly divided into two equal groups: The patients in the control group were to participate in a 60-minutes conventional training five times a week for three weeks, and the patients in the experimental group received 30-minute conventional training and then 30-minute backward walking training five times a week for three weeks. Before the training and 3 weeks after the training, Fugl-Meyer assessment was used to assess the motor function of the lower extremity (FMA-L), Berg balance scale (BBS) was used to assess the balance function, and 10 m maximum walking speed was measured.

Results: After the three-week training period, the FMA-L score of the experimental group was 28.0 +/- 3.3, significantly higher than that of the control group (25.5 +/- 2.3, P = 0.033); the BBS score of the experimental group was 51.4 +/- 1.8, significantly higher than that of the control group (47.3 +/- 3.7, P = 0.001, and 10 m MWS of the experimental group was 57 +/- 17, significantly higher than that of the control group (43 +/- 16, P = 0.034).

Conclusion: A safe and feasible intervention, additional backward walking therapy helps improve the damaged motor function, balance, and walking speed of the patients with stroke.
