Overview
Brief Summary
This RCT is to investigate the clinical effect of extracorporeal shock wave therapy (ESWT) compared to the local corticosteroid injection (LCI) in managing mild to moderate carpal tunnel syndrome (CTS).
Detailed Description
To investigate the effect of extracorporeal shock wave therapy (ESWT) compared to the local corticosteroid injection (LCI) in managing mild to moderate carpal tunnel syndrome (CTS). About 50-60 patients with mild to moderate CTS are supposed to be randomly allocated into either ESWT group or LCI group. The outcomes include the visual analog scale (VAS), the Boston Carpal Tunnel Questionnaire (BCTQ), and nerve conduction study at baseline and at 3 weeks, 9 weeks, 12 weeks, 6 months, and 12 months after the treatments.

Outcomes
Primary Outcomes
Boston Carpal Tunnel Questionnaire (BCTQ)
Time Frame: At 12 months after the treatments
Boston Carpal Tunnel Questionnaire (BCTQ) is the most widely used self-administered outcome scale in patients with carpal tunnel syndrome (CTS) for assessing patients' perceived symptom severity and functional status. The score ranges from 19 to 95. The higher score means a worse status of CTS.
The distal latency of the median compound motor action potential (CMAP)
Time Frame: At 12 months after the treatments
The distal latency of the median compound motor action potential (CMAP) is used to assess the function status of the median compound motor nerve. The value ranges from 0 ms. The less value means the quicker conduction of the action potential and the better function status of the nerve.
The amplitude of the median compound motor action potential
Time Frame: At 12 months after the treatments
The amplitude of the median compound motor action potential is used to assess the function status of the median compound motor nerve. The value ranges from 0 mV. The higher value means the better function status of the nerve.
Visual Analog Scale (VAS)
Time Frame: At 12 months after the treatments
The Visual Analog Scale (VAS) is frequently used as a tool to measure the degree of the pain felt by the participants. The score ranges from 0 to 10. The higher score means a higher degree of the pain.
The peak latency of the median sensory nerve action potential (SNAP)
Time Frame: At 12 months after the treatments
The peak latency of the median sensory nerve action potential (SNAP) is used to assess the function status of the median sensory nerve. The value ranges from 0 ms. The less value means the quicker conduction of the action potential and the better function status of the nerve.
The amplitude of the median sensory nerve action potential
Time Frame: At 12 months after the treatments
The amplitude of the median sensory nerve action potential is used to assess the function status of the median sensory nerve. The value ranges from 0 μV. The higher value means the better function status of the nerve.
