14. Grading of symptoms of tendinopathy
• Mild
Pain only after activity/pain that disappears with
activity
• Moderate
Pain with sporting activity but not with activities
of daily living
• Severe
Pain during activities of daily living
15. Grading of ligament sprains
Grade I
• Stretched fibers
• Normal ROM
Grade II
• Considerable portion of the fibers involved
• Increased laxity but a definite endpoint
16. Grading of ligament sprains
Grade III
• Complete
• Excessive laxity with no firm endpoint
17. Grading of muscle strains
Grade I
• Small number of fibers
• Localised pain
• No loss of strength
Grade II
• Significant number of fibers
• Pain and swelling
• Strength reduced
18. Grading of muscle strains
Grade III
• Complete tear
• Mostly at musculotendinous junction
19. 2. PRINCIPLES OF INJURY
PREVENTION
1. Correct biomechanics
2. Warm up
3. Stretching
- Static
- Ballistic
- PNF
20. Passive warm-up

Force
(N)
Does warm-up influence the
mechanical properties of the muscle?
Increases peak stretch
and peak force
Increases peak stretch
but decreases peak force
21. 1. Static stretching: 3 stretches held for 30
seconds
2. Stretch 3 times per day (high risk
inflexible areas)
3. Warm up and then stretch
4. Stretch a relaxed muscle
5. PNF stretching is preferred if ROM is
required in a very inflexible muscle
Stretching :practical points
22. PRINCIPLES OF INJURY PREVENTION
4. Taping and bracing
5. Protective equipment
6. Suitable equipment
7. Appropriate surfaces
23. PRINCIPLES OF INJURY PREVENTION
8. Appropriate training
a) Principles of training
- Periodisation/Overload/Specificity/
Individuality
b) Training methods
- Aerobic/Anaerobic/Strength/
Flexiblility/Speed/Agility/Skill
training/Cross-training
24. PRINCIPLES OF INJURY PREVENTION
9. Adequate recovery
- Warm down
- Whirlpools and spas
- Massage
- Rest and sleep
10. Psychological aspects
11. Nutritional aspects
25. 3. PRINCIPLES OF DIAGNOSIS
1. History
- Allow enough time
- Be a good listener
- Know the sport
- Discover the exact circumstances of
the injury
26. PRINCIPLES OF DIAGNOSIS
1. History (cont.)
- Obtain an accurate description of
symptoms e.g. pain/swelling/
instability/function
- Was there a previous similar injury
- Past injuries
- General health
27. PRINCIPLES OF DIAGNOSIS
1. History (cont.)
- Training history
- Equipment
- Technique
- Overtraining
- Psychological factors
- Nutritional factors
- Level of participation
28. ROLE OF AGE
• Weakest link in M/S system change according
to age
• General rule:
9-12 yr. growth plate injuries of the heel
13-14 yr. injuries upper tibial apophysis
15-18 yr. avulsion injuries pelvis
19-30 yr. muscle injuries
> 30 yr. tendon injuries
29. PRINCIPLES OF DIAGNOSIS
2. Examination
- Develop a routine
- Examine the other side, where
relevant
- Attempt to reproduce the
symptoms
- Assess local tissues
30. PRINCIPLES OF DIAGNOSIS
2. Examination (cont.)
- Assess for referred pain
- Assess neural tension
- Biomechanical examination
31. PRINCIPLES OF DIAGNOSIS
3. Investigations
- Understand the tests
- Know how soon changes can be
detected by investigations
- Only order investigations that will
influence management
32. PRINCIPLES OF DIAGNOSIS
3. Investigations (cont.)
- Be able to interpret tests
- Do not accept a poor quality
investigation
- Explain the investigations to the
patient
33. PRINCIPLES OF DIAGNOSIS
3. Investigations (cont.)
- Examples of investigations
Neurological (EMG/Nerve
conduction studies)
Muscular (compartment pressure/
dynamometry)
34. PRINCIPLES OF DIAGNOSIS
3. Investigations (cont.)
- Examples of investigations
Cardiovascular (ECG/Echocardio-
graphy)
Pulmonary (Lung function tests)
Radiological (CXR/RT/MRI/US)
36. 4. PRINCIPLES OF TREATMENT
Six principles of management:
1. Minimize the extent of initial damage
2. Reduce associated pain and inflammation
3. Promote healing of damaged tissue
37. Physiology of soft tissue healing
Inflammatory
Phase
Repair
Phase
Remodelling
Phase
Initially = prevent excess swelling and injury
w1-3 = collagen formation (protect from inversion)
>3w = collagen maturation
(controlled stress)
4-8w = full return to activity
38. PRINCIPLES OF TREATMENT
Six principles of management (cont.)
4. Maintain or restore
- flexibility
- strength
- proprioception
- overall fitness
39. PRINCIPLES OF TREATMENT
Six principles of management (cont.)
5. Functionally rehabilitate the injured
athlete to enable return to sport
6. Assess and correct predisposing factors
