Problem: Barriers to Physical Therapy

Grip strength is key to quality of life, but musculoskeletal, neuromuscular, and cardiovascular disorders, as well as injuries and aging can impair grip strength. Physical Therapy can help, but distance to service, cost, lack of transportation, and wait-lists are barriers preventing patients from getting rehabilitation.

Solution: At-Home Grip Strength Physical Therapy Device

Our device coaches patients through different grip strength exercises, providing convenient, custom grip-strength rehabilitation for anyone.

Design

A 100 kg load cell was placed in a custom grip and case. The signal was conditioned in three stages before being processed by an Arduino. An LCD screen run by the Arduino gave feedback to the user while a keypad took user input.

The custom case and grip were designed by me in PTC Onshape.

The case and grip were 3D printed for prototyping.
