According to engineers at Cleavland University, people with back injury use the wrong muscles and thereby put themselves at risk of further problems. Back injury is a common problem. People who have had a back problem tend to find it recurs. Researchers at the Biodynamics Laboratory have found that this is because they tend to protect their injury by creating a big stress on their spine afterwards.
This study comparedhe movement of injured and uninjured people. The engineers were able to use a mathematical technique to analyse movements of the injured volunteers without having them do the full action.
AdvertisementThey found that people with a back injury use the wrong muscles and create too much load on the spine, putting them at risk of further problems. Physical therapists will need to re-educate people in the use of the normal movements if they are to protect the spine. Losing weight can help because overweight causes more strain on the spine.
