Using the Ghostly app for strength training in hospitalized patients

Strength Training in Hospitalized Patients Using the Ghostly App: a Feasibility Study

Not applicable Interventional Vrije Universiteit Brussel · NCT05258500

This study is testing if using the Ghostly app for strength training can help hospitalized patients, like those recovering from a stroke, COVID-19, or who are frail, get stronger during their rehabilitation.

What this trial studies

This feasibility study evaluates the effectiveness of the Ghostly app in enhancing rehabilitation for hospitalized patients, specifically targeting stroke patients, frail elderly individuals, and those recovering from COVID-19. The study involves three randomized controlled trials that assess strength gains through a strength training program integrated into the app, which utilizes electromyography to measure muscle contractions. Participants will be divided into groups receiving either the Ghostly app, conventional therapy, or blood flow restriction during training. The app aims to provide a stimulating environment for muscle training by allowing users to control a character through their muscle contractions.

Who should consider this trial

Good fit: Ideal candidates include hospitalized individuals who are recovering from stroke, are elderly and frail, or are COVID-19 survivors with muscle weakness.

Not a fit: Patients with other disabilities, those unable to understand instructions, or those with metal implants or implanted electrical devices may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve rehabilitation outcomes and strength recovery for patients with muscle weakness.

How similar studies have performed: While the use of gaming apps for rehabilitation is a novel approach, similar studies have shown promise in enhancing patient engagement and outcomes in physical therapy.
