Research summary
As the UK population is getting older, more and more people are having shoulder joint replacement surgery. A particular shoulder joint replacement that swaps the position of the ball and socket, to improve movement when some of the tendons have torn, is becoming increasingly popular. The results of this “Reverse Total shoulder Replacement” (RTSR) are usually very good, but some patients do not achieve good movement and function post-operatively. It is not currently known why some people do well and others do not.
The aim of this study is to work out what the difference is in the movement pattern and muscle activity between patients with good and poor outcomes. Finding out which muscles are working too little or too much in patients that are not doing well, compared to those who are, will allow us to plan better rehabilitation programmes for future patients. It will also help us to work out which patients are likely to get good or poor results, enabling them to make more informed decisions when choosing to have surgery or not.
Our plan is to evaluate a number of patients (with both good and poor results) who have had RTSR to find out about their movement and muscle activity. We will use a series of assessments, including motion capture technique (videoing movement and using sensors to show what is happening), Electromyographic (EMG) analysis (measuring activity level of muscles during movements), and grip strength testing.
We have asked our patients who have had RTSR which movements are/were important to them when they chose to have the surgery, and these are the movements that we will be analysing. When we have completed the study, we will share results with other specialists in this area (surgeons and physiotherapists) through journals/conferences so that they can learn from our results.REC name
