What Can I Do to prevent RSI in my hand or wrist, that's as easy as 1-2-3?

Ergonomics in Dentistry & in the Workplace: Exercises to Prevent Thumb, Finger, Hand, Wrist, Carpal Tunnel & Elbow Injuries.

Repetitive grip injuries are a form of RSI (repetitive stress injury). They are common in many occupations, few more-so than in the dental profession. Dentists, dental hygienists and dental assistants are especially exposed to repetitive grip imbalances. Hand muscles cross many joints throughout the lower arm, and thus the usability of the fingers, thumb, hand, wrist, carpal tunnel and elbow often become compromised – especially over time.

Dental professionals rate HIGHLY in EACH category for exposure to repetitive grip injuries:

  • Aggressive, continuous grip, often with vibration

  • Long grip periods without a break

  • Non-neutral tool size gripped (small tool requires greater pinch effort)

  • Palm-down position during grip (greater effort to support wrist & fingers)

Common RSI injuries in the dental professional:

  • Carpal Tunnel Syndrome

  • Tennis Elbow & Cubital Tunnel Syndrome

  • Thumb, Small Finger & Wrist Tendinitis and Chronic Adhesion

  • Arthritis / Dequervain’s Tenosynovitis / Duyputren’s Contracture

Why Dentists, Dental Hygienists & Dental Assistants Use Handmaster Plus

Handmaster Plus is used by dental professionals as an easy ergonomic exercise to offset muscle imbalance and the effects of unavoidable chronic daily repetitive gripping.

One easy continuous exercise strengthens and balances the 9 muscles that close the hand as well as the 9 muscles that open the hand resulting in strong stable hands, wrists, carpal tunnels and elbows. Just minutes per day means better performance and a reduced risk of RSI injury as a result of repetitive gripping.
