Upper-body pain is one of many conditions massage clients present with. In a new study, researchers evaluated the relationship between muscle strength and pain in subacromial impingement syndrome, also known as tendinitis or bursitis of the shoulder.
Eighteen female and two male patients between the ages of 32 and 60 years with stage I and II subacromial impingement syndrome were enrolled in the study, according to an abstract published on www.pubmed.gov.
Upper, middle and lower trapezius, serratus anterior, supraspinatus and anterior deltoid muscle strengths were assessed bilaterally by a handheld dynamometer. Each muscle was assessed three times and the mean value of strength was calculated.
Pain and functional results were assessed with visual analog scale and Constant scores. Modified Constant score was calculated, with the exclusion of pain parameters.
The researchers found that middle trapezius, serratus anterior, supraspinatus and anterior deltoid muscle strengths of the shoulder with positive impingement signs were significantly lower than the healthy opposite side.
“The relationship of muscle strength and pain in subacromial impingement syndrome” was conducted by researchers at Department of Orthopedics and Traumatology, ?stanbul Medical Faculty, Istanbul University, ?stanbul, Turkey.
