正中神経麻痺 手根管症候群
Median nerve palsy Carpal tunnel syndrome
正中神経麻痺は手にとって最も重要な神経で、正中神経の傷害は、鋭敏な感覚と巧緻性を要求される手にとって致命的なダメージになります。症状としては、小指以外の指にしびれがある、母指(親指)に筋萎縮(筋肉が痩せる)がある、手首や手指の曲げ伸ばしが困難、親指と人指し指で丸を作りにくい、手のこわばりがある、夜中や明け方に痛みやしびれが強く出るなどがあります
鍼灸治療としては、痛みや痺れの強い部位に鍼を刺して血行を促進、血液による消炎作用を促します。また、正中神経の走行上の上腕部、前腕部にある筋肉の筋緊張を緩和し、圧迫や絞扼を緩和していきます。
Median nerve palsy is the most important nerve in the hand, and injury to the median nerve can be fatal to the hand, which requires acute sensation and dexterity. Symptoms include numbness in all fingers except the little finger, muscle atrophy (muscle thinning) in the thumb, difficulty in bending and extending the wrist and fingers, difficulty making circles with the thumb and index finger, stiffness in the hand, and pain and numbness that is stronger at night or at dawn.
As for acupuncture treatment, acupuncture needles are inserted into the area of strong pain and numbness to promote blood circulation and blood-mediated anti-inflammatory action. In addition, muscle tension in the muscles of the upper arm and forearm on which the median nerve runs is eased to relieve pressure and strangulation.
