TOS can be diagnosed with the application of several tests of mobility and sensation in the area, as well as an examination of the area for physical abnormalities. Attention to case history, such as whether the patient engages in repetitive, heavy lifting or other activity that could cause a repetitive stress injury, or whether the patient has recently suffered an injury that can lead to TOS, can also be of help in diagnosis. Most cases of TOS are resolved through rehabilitative therapy and exercise. A doctor or physical therapist can help to correct postural abnormalities that contribute to compression and establish an exercise program to strengthen the shoulder muscles and stretch the neck muscles.
If vascular impairment (cutting off of circulation to the area) is present, your doctor may recommend surgical decompression. Most TOS sufferers recover via non-surgical methods.
