Allocation Method

NA

Intervention Model

SINGLE_GROUP

All subjects received 18 sessions (3 times per week for 6 weeks) of seated robotic ankle training. Upon analysis, subjects were stratified by average admission gait speed on the 10 Meter Walk Test at comfortable pace, according to clinically established gait speed performance groups: low (\<0.4m/sec), moderate (0.4m/sec-0.8m/sec) and high (\>0.8m/sec) gait functioning.

seated robot-assisted ankle therapy

All participants received eighteen 1 hour sessions (3x/week for 6 weeks) of seated robot-assisted ankle training with the MIT anklebot. Upon analysis, subjects were stratified based on average admission gait speed on the 10 Meter Walk Test at comfortable pace according to clinically established gait speed performance groups: low (\<0.4m/sec), moderate (0.4m/sec-0.8m/sec) and high (\>0.8m/sec) functioning.

Group Type EXPERIMENTAL

seated robot-assisted ankle therapy

Intervention Type DEVICE

The MIT anklebot provides over one thousand total dorsi/plantar flexion and inversion/eversion robot-assisted movements of the ankle while in a seated position.
