Q

What is Carpel tunnel syndrome?

A

Median nerve located in the centre of the wrist that are protected by flexor muscles on the inside of the wrist, becomes damaged from overuse in extension positions such as cycling or rowing. This causes compression on the median nerve.

25
How to identify Angina?
A vice like pain in chest
26
how to treat exercise induced asthma
relieved by inhaler (blue - Ventolin) check they have this before exercise. respiratory trouble may also be caused by allergies.

where are abdomen injuries most common?
spleen and liver
28
what are the signed of an abdominal injury ?
- Rigidity - shock - rapid pulse - sweating
29
what are the signed of a kidney injury?
Kidney – bruising, bleeding in urine
30
what are the signs of an intestinal injury?
usually duodenal as close to surface. Rigidity. Usually a blow.
31
what are the signs of a bladder injury?
Traumatic blow – blood in urine * Blood in urine may also be underproduction of urine (not drinking + heavy exercise)
32
what are the signs of a urethra injury?
Traumatic blow, bleeding
33
what are dermatomes ?
segmental distribution of spinal nerve pain, lack of sensation in an area of dermatomemay indicate injury site
34
what does the transverses muscle do?
Transversus acts at initiation of movement to stabilise trunk in overhead and lower limb action
35
when are the internal obliques and transverses activated?
in hollowing actions.
36
What muscles are prime movers of trunk flexion?
Rectus abdominis and lateral fibres of external obliques
37
what is valgus of the foot ?
A position of Everton (foot outwards towards the lateral
38
What is Varus of the foot?
A position of inversion (foot inwards towards medial)
39
what is subtler neutral position of the foot?
Neither pronated nor supinated - dead of talus not protruding from behind navicular on either medial or lateral side.
40
Define pronation
A single motion whose component consists of adbuction, eversion and dorsiflexion of one segment or joint in relation to another (ie outwards & upwards)
41
Define Supination
A single motion. opposite to pronation (ie. inwards and downwards)
42
what is normal function of the foot?
Posteriolateral contact (5-7°)→pronation to neutral with internal tibial rot →femoral rotation (to absorb shock). Now mid-stance.
43
List and describe typical foot problems?
Excessive pronation - pain medial side of leg associated with high impacts as pronate for foot strike - excessive motion at subtalar joint. * Failure to re-supinate * Late pronation Related: tibial stress syndrome
44
What is cavus foot and its symptoms?
Rigid foot - cannot absorb as much impact Symptoms: Pain usually lateral aspect of lower leg (lateral impact) Related: Trochanteric bursitis, peroneal tendonitis
45
What is femoral torsion?
twist in femur shaft (in/out) during gait.
46
Describe Genu varum (bow legs)
Often have rigid, high arched feet – leads to supinated feet. Often increased range of pronation
47
Describe Genu Valgum (knock knees)
With femoral anteversion internal rotation * Large Q angle * Weakness of hip rotators * Tightness of adductors * Wide pelvis * Tight hamstrings and calves * Knock-on from excessive pronation
48
Describe Genu Recuvatum (hyperextended knees)
Ligament laxity * Increased stress on knees, muscular imbalance and increased pronation
49
What is a common orthoses ?
Common insert in midsole up to (10 deg varus/valgus) to adjust pronation and knee pain
50
What percentage of people were rear foot striker in Ket et al. (1983)?
81% Rear foot strike (19% midfoot, 0% fore foot)
51
Which footstrike is the most efficient?
Heel
52
In which foot strike is the impact peak delayed
Fore foot strike
53
Which foot strike causes increased forces through the achilles? What problem does this cause?
Fore foot strike. Achilles tendonopathy
54
Where do fractures of the shoulder occur and why?
Clavicle, this is the weakest structure in the shoulder
55
Who are acromioclavicular joint injuries most common in?
Young athletes, as part of a fall
56
What does IGHL stand for?
Inferior glenohumeroal ligament
57
What is the function of the rotator cuff?
Centres the humeral head in the glenoid and gives the other muscles power
58
What is the discrepancy of the shoulder joint?
4mm
59
What is the effect of translation and compression of the humeral head?
Entrapment of labarum between the humeral head and glenoid rim, this causes a labral tear
60
What does fatigue in pronator muscles cause?
Tensile strength of UCL increased and therefore there is more stress of UCL (ulnar collateral ligament)
61
Whats the function of the labarum?
Outside part of the cartilage allows for smooth moving of the humeral head
62
What are the training protocols for rotator cuff injuries?
Therabands, weigthed cables, pulling (external rotators), pushing (internal rotators), should be on both sides equally to strengthen
63
What is the effect of cortisone injections on tendons?
Weakens if over a longer period of time, can cause the tendons to harden
64
When is the chance of sciatica increased?
When the nerve runs through the middle of the hamstring group and underneath the periformis
65
What happens if the subtalar joint is not level?
The axis of movement is not directionally horizontal, its at an angle, increasing joint movement (eversion and inversion)
66
What effect does muscular imbalance have on loading?
Changes the loading between medial and lateral
67
What is the role of shoes?
Shock absorption, stabilization, flexibility, lightweight and support
68
Which footstrike is most economical?
Midfoot, faster with 7% more energy used
69
What footstrike is the fastest?
Forefoot
70
What factors determine footstrike patterns?
Speed of the action or the task
71
What is the effect of footstrike on oxygen uptake?
No difference, increase in carbohydrate oxidation
72
What could be the effect if an individual suddenly changes striking pattern?
Slow down or cause injury to the runner by putting unnecessary stress through the foot
73
Why is the impact peak invisible in force graphs of forefoot runner?
As they start in plantar flexion, initial force is expected to occur at the same time as the drive force
74
What is the relationship between ground reaction force and injury?
Greater ground reaction force and greater impact peak was found to have a lower injury rate
75
What is the injury risk of forefoot strikes?
Not metabolically efficient, no reduction in impact forces and no reduction in running related injuries
76
What is the difference in loading between FF and HS
FF - increase in calf and knee HS - increase in hip and knee
77
What injuries come from footstrike?
Achillies tendionopathy, plantar facitis and patellofemoral pain
