1. 1212 R S I or how evolution cannot keep up with our progress ARBOCATALOGUS Nederlandse universiteiten 2009-5045 ACNU KANS GP4b CANS presentation (UK version).ppt Subject: CANS Good Practice #4b: PowerPoint presentation CANS (UK)

2. 1212  RSI in 3 stages  Ergonomics  Posture  Prevention  What is RSI?  Diagnose, Symptoms  Direct causes  Indirect causes (risk factors) Subjects

3. 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

4. 1212 Diagnose RSI?  Most common(80%) is a painful  hand, arm, shoulder and neck  A medical diagnose in only 10 - 20%  Tennis elbow, golf elbow  Inflammation of tendon or tendon sheath  Carpal tunnel syndrome

5. 1212 Symptoms/Complaints  Local cramp and tiredness  Pain: nagging or sharp can radiate  Tingling (paraesthesia)  Loss of control and strength  Stiffness  Dysfunctions and restrictions

6. 1212 Neck 20 % Elbow 6 % Shoulder 19% Wrist/hand/fingers 11% (Dutch Labour Inspection examined in 1997, 2000 civil servants.)

7. 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

8. 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)

9. 1212 Causes may lead to  Nerve damage as a result of pressure  Straining of muscles and tendons

10. 1212 RSI complaints in 3 stages:  Light to very serious  Temporary to permanent  While working to lasting after work

11. 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

12. 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

13. 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

14. 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

15. 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)

16. 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
