ClinConnect Summary

The mGain trial is studying a new therapy to help people with weakness in their arms due to conditions like stroke, nerve injuries, or even after limb amputation. The therapy uses a special device that connects to a mobile app and provides feedback to make exercises more engaging and fun. Researchers believe that this approach will encourage participants to stick to their therapy better than traditional methods. The study will last for four weeks, with participants doing therapy for 30 minutes a day, five days a week, and they will visit a study site at the beginning and end for assessments.

To join the trial, participants need to be 18 years or older and have some weakness in their arms due to specific conditions, such as recent nerve injuries or amputations. They should also be able to use a smartphone or tablet and commit to the exercise routine. This is an exciting opportunity for those who qualify, as it may not only improve their upper limb function but also provide a more enjoyable way to do therapy.
