“It’s been really useful to help rehabilitate my knee injury. Being able to see the data and the improvements helped inform my rehab and recovery process. Great product!”

How It Works

Medical Profession

Musculoskeletal injury rehabilitation from the comfort of your own home.


With the GS Trainer, you can easily and quickly perform a muscle peak force assessment of any particular major joint or action e.g. shoulder, knee, hip. The GS Trainer will register and define the forces that each muscle group can generate.

This data can be used for development of pre-operative “prehab” programmes and post-operative rehabilitation. It can provide an immediate objective injury assessment as well as populating patient reported outcome measures. Essential pre and postoperative informative data can be instantly delivered to surgeons and their patients who are scheduled or undergoing surgery.
