Exercise plays a very important role in being prepared for your first prosthesis. You will find that the stronger and more flexible you are, the easier it will be to work with your new prosthesis. Your physical therapist will help by teaching you some exercises specific to your unique needs. People often can begin their exercising while they are on bed rest and then increase the amount and type of exercise as they heal. There are massage exercises to prepare the stump for continual contact with the prosthetic.
