简要总结
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.

入选标准
- •Neck / shoulder pain has to last more than 12 weeks', with an average score higher than 2 on a 11-point Numeric Pain Rating Scale within the last 24 hours and during the week before data collection.
- •All subjects will have to work for a minimum of four hours per day using a computer, should speak and understand English, and could not be involved in regular strength training of the neck/upper extremities
排除标准
- •previous whiplash; a history of neurological or mental illnesses; consumption of pain killers within the last 24 hours; drug addiction, defined as the use of cannabis, opioids or other drugs; fibromyalgia; previous cervical spine or upper limb surgery; carpal tunnel syndrome; concomitant injury or pain from the lumbar spine; and heart diseases or hypertension.
研究组 & 干预措施
Eccentric Training Group
Eccentric training of the upper trapezius muscles. The intervention will consist of ten sessions of 25-30 minutes (twice a week over 5 consecutive weeks) of eccentric exercises of the shoulder muscles, as neural activation increases after 4 weeks of eccentric training. The total duration of the intervention will be 2 hours and a half.
干预措施: Eccentric Training Protocol (Device)
结局指标
主要结局
Neck disability, assessed by the Neck Disability Index (NDI)
时间窗: Change from Baseline to Neck Disability Level after a two-week intervention protocol
The NDI is a valid and reliable tool, frequently used to assess functionality in workplace interventions
Pain Intensity, assessed by a 11-point Numeric Pain Rating Scale (NPRS)
时间窗: Change from Baseline to Pain Level after a two-week intervention protocol
It will be measured the worst pain within the last 24 hours and the average pain intensity during the previous week
Upper limb function, assessed by the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire
时间窗: Change from Baseline to Upper extremity Disability Level after a two-week intervention protocol
The DASH questionnaire is the most recommended scale to assess individuals with shoulder disorders
