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.

Condition or disease Intervention/treatment Phase
Carpal Tunnel Syndromes Other: Physical Therapy Group Procedure: Surgical Group Not Applicable

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.

Arm Intervention/treatment
Experimental: 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.
 Other: 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.
Active Comparator: 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.

Outcome Measures

Primary Outcome Measures :
  1. 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 Outcome Measures :
  1. Changes in active cervical range of motion between baseline and follow-up periods [ Time Frame: Baseline and 1, 3, 6 and 12 months after the intervention ]
    A cervical range of motion (CROM) device will be used to assess cervical range of motion in a single direction: flexion, extension, lateral flexion toward or away from the side of the CTS, and rotation toward or away from the side of the CTS. For patients with unilateral symptoms, sides are classified as affected or unaffected whereas in those with bilateral symptoms, the most painful side will be considered as the affected side and the less painful side as the unaffected side.

  2. Changes in pinch grip force between baseline and follow-up periods [ Time Frame: Baseline and 1, 3, 6 and 12 months after the intervention ]
    Pinch grip force between the tip of the thumb with the tip of the index or the little finger will be measured with a pinch grip dynamometer
