Clinical Trial Summary

The purpose of this Phase I study is to conduct a pilot clinical trial using a mobile app-connected, wire-free surface electromyography (sEMG) system, called mGain, that provides biofeedback-based therapy in individuals with upper limb weakness due to neurologic injury or with upper limb amputation. Our overarching hypothesis is that the mGain wireless sEMG device and mobile therapeutic gaming environment will demonstrate improved adherence to therapy when compared to standard of care and will be feasible, acceptable, and usable in individuals with upper limb weakness or limb amputation. All participants will undertake four weeks of therapy. Conducting therapy five days a week for 30 minutes a day. In addition, participants will have an initial and final assessment visit at a study site, with each visit expected to last 1-2 hours.


Description:

All participants will undertake four weeks of therapy. Conducting therapy five days a week for 30 minutes a day. In addition, participants will have an initial and final assessment visit at a study site, with each visit expected to last 1-2 hours. Initial Assessment: Eligible individuals will complete a baseline assessment including range of motion, manual muscle testing, and handheld dynamometry of the target limb(s). Target muscles for therapy will be identified (e.g., biceps, triceps, deltoids, forearm flexors, forearm extensors) and a trial of sEMG evaluation to detect muscle signal will be conducted. If detectable muscle signal is present, participants will complete the consent process and be enrolled in the study. Each participant will be taught the use of the mGain system using their own mobile phone or tablet and be given a therapeutic regimen to target their individual muscle weakness. Participants will then be asked to demonstrate use of the system. Participants can ask questions to ensure they understand system usage and the expectations when at home. Participants will complete baseline validated outcome measures such as the QuickDASH (Disabilities of the Arm, Shoulder and Hand questionnaire) and PROMIS Self-Efficacy Scale. Home Therapy: For the four weeks following the initial assessment, participants will be asked to conduct a minimum of 30 minutes of therapy per day, 5 days a week, at home using the mGain system targeting the muscles identified during the initial assessment. Individuals will be asked to complete short questionnaires and write in an eDiary about their experience after conducting their daily exercises. A member of the study team will contact the participants on a weekly basis to provide technical support, inquire about adherence, and encourage participation. Data for each participant will be uploaded to Orthocare Innovations' HIPAA compliant cloud-based server. Final Assessment: Participants will complete a final assessment of strength, range of motion, and manual muscle testing. Additionally, participants will complete outcome measures and surveys such as the QuickDASH, PROMIS Self-Efficacy, system usability scale, and a custom feasibility survey.

Outcome

Type Measure Description Time frame Safety issue
Primary Pre Self-Efficacy The PROMIS Self-Efficacy is a validated patient-reported questionnaire that measures an individual's confidence in the ability to perform specific tasks or behaviors in a variety of situations; developed under the Patient-Reported Outcomes Measurement Information System (PROMIS) program; results in a T-score where 50 is the mean and T-scores below the mean indicate less self-efficacy. At initial assessment before using intervention
Primary Post Self-Efficacy The PROMIS Self-Efficacy is a validated patient-reported questionnaire that measures an individual's confidence in the ability to perform specific tasks or behaviors in a variety of situations; developed under the Patient-Reported Outcomes Measurement Information System (PROMIS) program; results in a T-score where 50 is the mean and T-scores below the mean indicate less self-efficacy. Four weeks (at final assessment after using intervention for four weeks)
Primary System Usability Scale The System Usability Scale measures the usability of a system and is a 10-item questionnaire completed by the participant; results in score 0-100 where scores above 68 would be considered above average. Four weeks (at final assessment after using intervention for four weeks)
Secondary pre-QuickDASH QuickDASH (Disabilities of the Arm, Shoulder and Hand) is a validated patient-reported questionnaire that measures physical function and symptoms in people with musculoskeletal disorders of the upper limb; results in score 0-100 where 0 represents the least disability and 100 represents the greatest disability At initial assessment before using intervention
Secondary post-QuickDASH QuickDASH is a validated patient-reported questionnaire that measures physical function and symptoms in people with musculoskeletal disorders of the upper limb; results in score 0-100 where 0 represents the least disability and 100 represents the greatest disability Four weeks (at final assessment after using intervention for four weeks)
