About this trial
This project will develop a wearable rehabilitation robot suitable for in-bed acute stage rehabilitation. It involves robot-guided motor relearning, passive and active motor-sensory rehabilitation early in the acute stage post-stroke including patients who are paralyzed with no motor output. The early acute stroke rehabilitation device will be evaluated in this clinical trial.

Trial outcomes
Primary outcomes
Fugl-Meyer Lower Extremity (FMLE)
The Fugl-Meyer Lower Extremity (FMLE) assessment is a measure of lower extremity (LE) motor and sensory impairments. The FMLE scale ranges from 0 to 34, with higher scores indicating better motor function.
Secondary outcomes
Active range of motion (AROM)
AROM will be measured in degrees in the ankle joint while subjects use the muscles to move the ankle.
Passive Range of Motion (PROM) will be measured in degrees in the ankle joint while the robot moves the ankle of the subject strongly.
Passive Range of Motion PROM will be measured in degrees in the ankle joint while the robot moves the ankle of the subject strongly.
Strength of the ankle flexor-extensor muscle will be measured in Newtons
Strength of the ankle flexor-extensor muscle will be measured in Newtons
Modified Ashworth Scale (MAS)
The Modified Ashworth Scale is the most widely used assessment tool to measure resistance to limb movement in a clinic setting. Scores range from 0-4, with 6 choices. 0 (0) - No increase in muscle tone; 1 (1) - Slight increase in muscle tone, manifested by a catch and release or by minimal resistance at the end of the range of motion when the affected part(s) is moved in flexion or extension; 1+ (2) - Slight increase in muscle tone, manifested by a catch, followed by minimal resistance throughout the remainder (less than half) of the ROM (range of movement); 2 (3) - More marked increase in muscle tone through most of the ROM, but affect part(s) easily moved; 3 (4) - Considerable increase in muscle tone passive, movement difficult; 4 (5) - Affected part(s) rigid in flexion or extension.
