Research summary
The hip joint is a ball and socket joint where the ball inserts into the socket. The ball shape is round but sometimes the ball has a bony bump on it. When the ball moves in the socket, the bump can hit the edge of the socket causing pain in movements like squatting or kicking a ball. Repeated hitting of the bump in the socket can cause hip pain, damage, and arthritis. This is called hip impingement and is found in 10-15% of young adults.
Does Physiotherapy treatment work?
Exercises from a physiotherapist make the muscles stronger around the hip joint which alters the way the ball moves. This stops the bump hitting the socket and this can help reduce the pain. However, an experiment found only 32% of people doing exercises got better. So, why after strengthening the muscles are some people still in pain? Is there another source of pain?Other causes of pain?
We know things like people’s emotions such as ‘feeling down’ can affect pain levels even if your muscles are strong. In this situation, strengthening your muscles may not be the best choice. We need to know more about types of pain in people with hip impingement to give better treatment.Our aim is to see why people with hip impingement still have pain after they have finished their physiotherapy treatment. This will be done by collecting information from questionnaires looking at emotions, pain beliefs and views on hip impingement at the beginning of a physiotherapy program. Then, after 6 physiotherapy treatments, we will gather further information from the questionnaires. We will then compare questionnaires to see if we can identify any reason for ongoing pain. This should help us tailor physiotherapy treatment to the individual and improve their outcome.
