“Rehabilitation ”

Reviewed by Anonymous

Recommended by surgeon following pelvic fracture. Excellent results on non weight bearing leg. Wasted muscles returned after 10 days of use in combination with Physio and Hydrotherapy. My programme of four exercises takes 2 hours to complete. Make sure to have water to hand - you get hot and thirty.
