1212 RSI in 3 stages Ergonomics Posture Prevention What is RSI? Diagnose, Symptoms Direct causes Indirect causes (risk factors) Subjects
1212 RSIRepetitive Strain Injury Repetitive=repeated Strain =too much tension Injury =damage The RSI syndrome is a collective name for complaints from overstraining as a result of repeated work
1212 Diagnose RSI? Most common(80%) is a painful hand, arm, shoulder and neck A medical diagnose in only % Tennis elbow, golf elbow Inflammation of tendon or tendon sheath Carpal tunnel syndrome
1212 Symptoms/Complaints Local cramp and tiredness Pain: nagging or sharp can radiate Tingling (paraesthesia) Loss of control and strength Stiffness Dysfunctions and restrictions
1212 Neck 20 % Elbow 6 % Shoulder 19% Wrist/hand/fingers 11% (Dutch Labour Inspection examined in 1997, 2000 civil servants.)
1212 Direct causes Static load: continuous (over)straining of the muscles in neck, shoulder, arms and fingers Dynamic load: Repeated movements in combination with extreme postures
1212 Indirect causes (Risk factors) 5 W ’s Working times (duration) Work pressure (deadlines, stress) Work place (furniture, equipment) Work method(visual aspects, instructions) Work tasks (organising tasks)
1212 Causes may lead to Nerve damage as a result of pressure Straining of muscles and tendons
1212 RSI complaints in 3 stages: Light to very serious Temporary to permanent While working to lasting after work
1212 Phase 1: Rookie Pain during work or after extensive work Complaints are local Clear relation between work and pain Phase 1 can last for years
1212 Phase 2: Experienced Pain radiates Pain and tiredness do not disappear entirely after work Work can become restricted Complaints occur during normal daily activities
1212 Phase 3: “Die hards” Continuous pain even at night Pain can transfer to other limbs Work can become impossible Injury can become permanent Even light activities can be very painful
1212 Conclusion… The problem is real ”THE SOLUTION” doesn’t exist Prevention is better than curing Variation in activities Awareness of (physical) stress Balance in the 5W’s
1212 The 5 W’s Working times (duration) Work pressure (deadlines, stress) Work place (furniture, equipment) Work method(visual aspects, instructions) Work tasks (organising tasks)
1212 Workplace, Posture and Method Ergonomics Ergon = work Nomos = rule, law “Learn from yesterday, live for today and hope for tomorrow. The important thing is to not stop questioning ” Albert Einstein
