Study Overview
Brief Summary
This randomized clinical trial will investigate changes in hand function, active cervical range of motion and pinch grip force after the application of physical therapy in women with carpal tunnel syndrome (CTS). The purpose of this study is to compare changes in function, cervical range of motion and pinch grip force induced after the application of a physical therapy program including manual therapies targeted to those areas related to the median nerve or after endoscopic surgery in women with CTS at medium and long-term follow-up. The hypothesis is that manual therapy is more effective for increasing cervical range of motion and pinch grip force, but similarly effective for improving function, than surgical treatment in women with CTS.
Detailed Description
There is some evidence suggesting that CTS is associated with restricted cervical range of motion and deficits in pinch grip force. In fact, restricted cervical range of motion and deficits in pinch grip force seems to be independent of electro-diagnostic findings. These findings would be associated with the proposed "double crush syndrome" theory. However no longitudinal studies have been conducted. Further it has been demonstrated that hand function is associated to deficits in these outcomes. Since previous studies support the use of physical therapy and surgical interventions for the management of function in these patients, the aim of this study is to conduct a randomized clinical trial to determine if changes in hand function are related to changes in active cervical range of motion and pinch grip force after the application of a physical therapy program including manual therapies targeted to those areas related to the median nerve or endoscopic surgery in women with CTS.

Arms & Interventions
Physical Therapy Group.
The physical therapy group will receive 3 treatment sessions of manual therapies including maneuvers targeted to the areas anatomically related to the median nerve (i.e., cervical spine, shoulder, elbow and wrist) of 30min of duration, once per week.
Intervention: Physical Therapy Group (Other)
Surgical Group
The surgical group will receive a surgical procedure consisting of the decompression and release of the median nerve at the carpal tunnel performed by an experienced surgeon according to standardized protocols.
Intervention: Surgical Group (Procedure)
Outcomes
Primary Outcomes
Changes in hand function between baseline and follow-up periods
Time Frame: Baseline and 1, 3, 6 and 12 months after the intervention
The Spanish version of the Boston Carpal Tunnel Questionnaire (BCTQ) will be used to assess function. This questionnaire evaluates 2 domains: 1) the functional status scale assesses ability to perform 8 common hand-related tasks; and, 2) the symptom severity scale includes 11 items assessing pain severity, numbness, and weakness at night and during the day. Each question is answered on a 5-point scale (1: no complaint; 5: severe complaint), with higher scores indicating greater severity. In the current study the score of the functional status scale of this questionnaire will be used as the main outcome.
Secondary Outcomes
- Changes in pinch grip force between baseline and follow-up periods(Baseline and 1, 3, 6 and 12 months after the intervention)
- Changes in active cervical range of motion between baseline and follow-up periods(Baseline and 1, 3, 6 and 12 months after the intervention)
