To test the effectiveness of HILT combined with a conventional physical therapy program to reduce pain intensity, sensory and motor nerve distal latency, and increase grip strength in pregnant women with CTS compared with the physical therapy alone.

Fifty-four pregnant women with mild to moderate CTS were randomized and further allocated into two groups. The HILT group (n = 27) received both HILT and conventional physical therapy, and the control group (n = 27) received only physical therapy, including nerve and tendon gliding exercises and the use of an orthotic device.
