As a HCPC registered PT/ Physical Therapist/Physiotherapist specialist in Rehabilitation my work frequently involves coaching people who have had life changing injuries. This process is not intended to be a medical treatment or therapy so please do get advice if needed from your physician. However all processes can be done in the imagination or with the unaffected arm. Thinking through movement processes will trigger cortical activity which a stage in activating movement memory. 

During any process movement should be pain free and only completed in small segments. A couple of minutes of repetition a few times a day to start is better than dedicating 30 or 40 minutes in one go. 

I look forward to hearing your feedback.
