Brief summary (from the registry)
Objectives: The aims are to 1) evaluate the clinical impact of eccentric training in female computer users with chronic NSP, 2) compare pressure hyperalgesia, temporal summation of pain (TSP), and conditioned pain modulation (CPM) in female office workers with and without NSP, and 3) assess changes in central pain responses after training. Methods: In part A, twenty office workers with NSP will be compared with 20 healthy controls. In part B, the NSP group will undergo a 5-week eccentric training program. Participants will report their pain intensity, and complete the Neck Disability Index, and the Disabilities of the Arm, Shoulder and Hand questionnaire. Pressure pain thresholds (PPTs) will be assessed over the neck and forearm. Cuff algometry will identify pain detection (PDT) and tolerance thresholds (PTT). TSP will be evaluated by visual analogue scale pain scores during 10 repetitive cuff stimulations. CPM will be calculated as the difference in PDT with and without a conditioning painful stimulus. Outcomes will be measured at baseline and post-intervention.
