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
Risk Factors:• May be caused by repetitive
motions but studies have not proved it.
• Most common for 30-60 y/o, esp. women.
• Cyst, tumor, bone fractures
• Anatomy = small tunnel• Arthritis (both types) &
diabetes• Obesity, Alcohol abuse,
fluid retention
Treatment Optionsfor Carpal Tunnel Syndrome
Non-Surgical Therapy: Wrist Splinting, NSAIDs, Corticosteroids (oral & injections), Warm/Cold compresses, Ergonomics, Exercise & Stretching
