In any industry, we find hazards of repetition, force, and awkward posture.
The muscles that control our fingers are located in the forearm, and tendons connect these muscles to the bones in our fingers and hands.
When we move our fingers, the tendons slide under a band of tissue at the front of our wrist. This band of tissue and the bones in the wrist form the carpal tunnel, and it doesn’t take much pressure or bend to constrict the carpal tunnel. You can take steps to prevent carpal tunnel.
How to Prevent Carpal Tunnel, and Other Wrist and Upper Limb Injuries
Reduce the following:
- Repetitive hand, wrist, or finger movements
- High force gripping or finger pressure
- Awkward postures of the wrist
- Direct pressure at the base of the palm
- Direct pressure across the front of the wrist
- Exposure to vibrating tools
- Exposure to cold
When tendons slide back and forth, they create a small amount of friction. With enough friction, wear and tear can occur, causing swelling.
“Tendonitis” is when tendons or their sheaths swell and there is pain or tenderness. Bending the wrist, the carpal tunnel constricts. Now the tendons have an even smaller opening to move through, creating more friction.
With Tendonitis People Can Experience:
- A “pins and needles” feeling in the hand (often at night)
- A reduced range of motions in the wrist
Identify hazards in your environment so you can minimize and eliminate them!
