27 Carpel Tunnel Syndrome What is it? A progressively painful hand/arm condition Caused by excessive pressure on median nerve SYMPTOMS: Tingling & Numbness Radiating pain Weak grip

28 Risk Factors: May be caused by repetitive motions but studies have not proved it. Most common for y/o, esp. women. Cyst, tumor, bone fractures Anatomy = small tunnel Arthritis (both types) & diabetes Obesity, Alcohol abuse, fluid retention

29 Treatment Options for Carpal Tunnel Syndrome Non-Surgical Therapy: Wrist Splinting, NSAIDs, Corticosteroids (oral & injections), Warm/Cold compresses, Ergonomics, Exercise & Stretching SURGERY ENDOSCOPIC SURGERY OPEN SURGERY Carpal Tunnel : Median Nerve Stretches for Relieving Carpal Tunnel
