  3. Tendonitis • Normal tendon glides smoothly in a tendon sheath • When under pressure, the capillary flow to the sheath is temporarily interrupted • When blood supply returns, swelling occurs

  4. Carpal Tunnel, inside of Wrist • Inside view of right wrist • Yellow nerve crosses under flexor retinaculum • Nerve has to share the space with nine tendons and tendon sheaths

  5. Cubital Tunnel, or ‘Funny Bone’ • The ulnar nerve passes by the inside of the elbow through a fibrous tunnel • Swelling can put pressure on the ulnar nerve • Symptoms are felt at the elbow and into the little finger • This is called Cubital Tunnel Syndrome

  6. Warning Signs • Watch for: • Tingling or numbness in hands • Pain: sharp, dull or burning sensation • Stiffness, reduced range of motion in arms, wrists • Clumsiness, loss of grip strength or coordination • Visual fatigue, watery eyes, dryness

  7. Prevention Hypotheses • Reduce force • Neutral posture (straight wrist) • Reduce repetitions • Ergonomic changes • Work breaks and/or stretching • Job rotation • General Health

  8. Ergonomic Workstations BETTER Adjustable Accessories BAD

  9. Ergonomic Risk Factors • Awkward positions • Static postures • Repetitive motion • Forceful exertion • Contact pressure

  10. Reaching Risk Factors • Elbow • Arm/Wrist • Shoulder • Back • Elbows in • Face the object you are reaching for

  11. Ergo Chairs & Accessories Features/Adjustments: • Height • Seat pan (width/depth) • Backrest height • Backrest tilt • Backrest tension • Armrests • Casters

  12. Monitor Accessories • Screen height at eye level (exception: bifocals and trifocal lens wearers). • about arms length away • Room lighting -avoid backlight, shadows or reflective glare • Flat Panel-lighter easier read
