People with upper-limb amputation try the TASKA GEN2 multi-grip bionic hand and compare it with other popular prostheses
Official title: Prospective Multicentre Randomized Cross-Over Study Evaluating Specific Function of Upper-Limb Amputee Patients Using the Multi-Grip Myoelectric Hand Prosthesis GEN2 Versus Other Multi-Grip Myoelectric Hand Prostheses
Run by TASKA Prosthetics · NCT07876115 · Data updated 2026-11-12
Adults with upper-limb amputation test the TASKA GEN2 hand to see if it improves daily function and comfort compared with their current prosthesis.

Is this trial a fit for you?
✓Likely a good fit
Adults over 18 with unilateral transradial or transhumeral amputation who currently use a Michelangelo or I-Limb Ultra prosthesis for at least 2 months and wear their prosthesis for more than 6 hours daily.
✕Probably not a fit
Individuals with bilateral upper-limb amputation, shoulder disarticulation, or conditions preventing follow-up may not benefit from this study.

What this trial studies
This multicenter, randomized cross-over study compares the TASKA GEN2 multi-grip myoelectric hand with marketed prostheses (Michelangelo or I-Limb Ultra) in adults with transradial or transhumeral amputation. Participants wear each device in two 28-day periods, with an additional 8-week extension for those starting with GEN2 in period 2 to gather longer-term data. The primary endpoint is the change in the Patient-Specific Functional Scale from baseline after each wearing period. Secondary outcomes include measures of upper-limb function, comfort, quality of life, satisfaction, and safety. The study is post-market and focuses on real-world use in multiple clinical sites.
Why it matters
Potential benefit: If successful, patients may experience improved hand function and quality of life with the TASKA GEN2 compared with their current prosthesis.
How similar studies have gone: Previous studies of multi-grip myoelectric hands have shown functional benefits in some populations, but results vary by device and user.
