Efficacy of Laser Acupuncture on Neurophysiological Parameters of Median Nerve in Postpartum Women

Study Overview
=================
Brief Summary
-----------------
BACKGROUND: Carpal tunnel syndrome (CTS), the most common entrapment neuropathy of the upper extremity, is caused by compression of the median nerve as it travels through the carpal tunnel CTs is a very common complication found in pregnancy, which is reported as high as 62% in pregnant females. The functioning of median nerve is compromised in almost all pregnant females especially during the third trimester of pregnancy, the majority may still feel some symptoms up to 3 years after delivery. Many clinicians have used LLLT on acupuncture points, which is called laser acupuncture (LA), to treat many clinical problems, such as musculoskeletal pain, lateral epicondylitis, headaches, etc. In contrast with traditional acupuncture needles, LA is a non-invasive therapy that does not cause tingling/pain during procedures Objective: to determine efficacy of laser acupuncture on electrophysiological parameters of median nerve in postpartum women

Detailed Description
-----------------
Intervention description Experimental Group: Each patient in this group will receive laser acupuncture on PC4 (Ximen), PC6 (Neiguan), PC7 (Daling), PC8 (Laogong), LI4 (Hegu), LI10 (Shousanli), LI11 (Quchi), HT3 (Shaohai), HT7 (Shenmen), LU10 (Yuji) acupoints in addition to wearing night splint. LA will be applied to each acupuncture point for 10 s with at least 4J/points based on the recommended LLLT treatment doses for CTS of the World Association of Laser Therapy. Control Group: Each patient in this group will wear night splint every night for 4 weeks
