Injury
• Load exceeds the ability– Trauma– Overuse
• Injury may happen to – Muscles, Ligament, Joints of– Spine, Hip, Knee and Ankle
Inflammation
• Normal body response to ‘problem’• Acute phase - Increased circulation
– Sign and symptoms• Redness, Swelling, Increase temp, Pain
– Management• Control sign and symptoms• R.I.C.E
Inflammation• Sub-acute stage
– Repairmen of the damage– Management
• Controlled activities
• Chronic Stage– Remodeling– Scar formation– Management
• Restoring normal function• Range, Strength, Power, Endurance,

Management for Hypothermia
Musculoskeletal Injury
Musculoskeletal Injury• Load exceeds the ability
– Trauma– Overuse
• Injury may happen to – Muscles, Ligament, Joints of– Spine, Hip, Knee and Ankle
Overuse injury
• Muscle strain / Cramp• Anterior knee pain• Iliotibial band friction syndrome (I
TB)• Plantar fasciitis (Sole / Heel pain)• Tendonitis (Knee, ankle)
Muscle Cramp / Strain
• Dehydration / Insufficient electrolytes– More generalized– Water and electrolyte supplementation
• Muscle fatigue– During / after exercise– Accumulation of lactic acid– Training, improve circulation
• Overload - damage– Concentric – muscle shortening– Eccentric – muscle lengthening – Training, aid / support
Muscle cramp
• Management– Replenish of water and electrolyte– Rest– Stretching– GENTLE massage
Anterior Knee pain /ITB syndrome
• Front knee pain and Side knee pain• Repeated loading (Overuse)• Related to
– Mal-alignment / Biomechanical fault– Insufficient hip, knee & ankle control – Insufficient flexibility– Increase loading to the patellofemoral join
t / distal portion of ITB

HKSI Sports Medicine Education Series IV
Iliotibial Band Friction Syndrome
Plantar Fasciitis
• Heel pain• Loading exceeding th
e flexibility of plantar fascia– Overweight– Increase pronation
Plantar Fasciitis
• Inflammation of tendon
• Overuse due to Repeated concentric eccentric cycle
Tendonitis
Traumatic Injury
•Ligamentous sprain•Muscle tear•Fracture•Dislocation
Traumatic Injury
Ligamentous and Muscle Injury
• Grade I to III– Grade I – Minor injury, no laxity, function
well preserved– Grade II – Moderate Injury, Laxity (lig.), f
unctional disturbance– Grade III – Complete torn, Laxity or even
dislocation, Great functional disturbance

How do you prepare yourself
• Reasonable goal• Reasonable training regime• Training log book• Addressing extrinsic factors &
intrinsic factors leading to injury
Extrinsic factor
• Temperature, Humidity, UV Index, Wind ….
• Trail surface and condition• Lighting• Gear – Clothing, Footwear,
Hiking pole, Flashlight / Headlamp, …

Guidelines for stretching
• Know the muscle direction and location
• Chose a stable position• Slow and steady stretch• Avoid overstretch• Normal breathing• Hold for 15-20 seconds• Repeat 2-4 times
Recommendation
• Before the walk and after long rest
• Water break / Check point• Slow and steady• Change of degree of tightness• Support

Choice of Shoes
Function of Shoes
• Maintain foot stability• Shock Absorption• Provide firm lever system for
propulsion
Foot Type and Stability
Optimum Rigid Floppy
Neutral Cushion Support
Neutral High Arch Flat Feet
Choice of Shoes
• Trainer for Section 1,2, 8 to 10• Hiking shoes / boot at night
when poor vision may lead to twisting of ankle
• Hiking shoes / boot for rainy day for Section 1 as it’s slippery in San Wan Shan’s trail
Blister Management
• Check whenever feel feet discomfort
• Blister may form in pressure area with repeated rubbing
• Advice– Good fitting shoes– Change socks– Double layers socks– Apply cream– Apply second skin
• Application of second skin
• Secure it with tapes
• Avoid creating another pressure area
