About this trial

This study will test the ability of myoelectric interface for neurorehabilitation (MINT) training to improve walking function.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Age at enrollment is 18 to 85

Leg impairment from unilateral stroke at least 6 months prior to screening

Severe to moderate gait impairment (ambulatory with a maximum walking speed of 0.8 m/s, i.e., half of normal speed)

Able to stand without assistance

Disqualifiers

Cognitive impairment with at least moderately impaired attention on digit-span test, or unable to follow instructions of the MINT task

Visual impairment (such as hemianopia) preventing sufficient perception of the screen to play the games

Anesthesia or severe neglect in the affected leg, or visual hemineglect (score of 2 on the NIH Stroke Scale Extinction and Inattention subtest) that impairs ability to play the games

Participation in another study on the affected leg, or any pharmacological study, within 6 weeks of enrollment

Trial design

Design model

Parallel

Treatments tested in this trial

  • myoelectric interface for neurorehabilitation (MINT) conditioning

    Other intervention

    Myoelectric interface for neurorehabilitation (MINT) conditioning involves training to reduce abnormal co-activation of limb muscles to improve movement.

  • One muscle myoelectric feedback

    Other intervention

    Training to control muscle activity in one muscle only.
