30
Biaxial joints
Two planes of movement Ellipsoidal joint (two ovals): E..g. radial-carpal joint Condyloid joint: e.g. metacarpophalangeal joint Saddle joint: e.g. thumb
31
Triaxial joints
three planes of motion Ball & socket joint: Hip, Shoulder
32
Arthrokinematic Principles of Movement
1. Convex-on-concave surface movement: Convex member rolls and slides in OPPOSITE direction 2. Concave-on-convex surface movement: Concave member rolls and slides IN THE SAME direction
33
What is a closed-packed joint position?
Surface of the joint's segments match each other perfectly in only one position of congruency - Max area of surface contact occurs - Attachments of ligaments are farthest apart & under tension - Capsular structures are taut - Joint is mechanically compressed, difficult to distract (separate) - Fully extended (e.g. knee locked, all ligaments fully stretched)
34
What are loose (open)-packed joint positions?
Joint surfaces do not fit perfectly, are incongruent - Ligamentous & capsular structures are slack (X stretched/ X taut) - Joint surfaces may be distracted (separated) several millimetres - Allow the necessary motions of spin, roll & slide
35
What is the name of the position the joint is in when it is at rest (resting position)?
Loose-packed joint position - position where there is least congruency & capsule & ligaments are loosest/most slack
36
What is active movement?
Movement driven by muscle contractions - through lengthening/shortening You perform this movement
37
What is passive movement?
Movement effected by examiner or gravity Examiner - External forces Gravity - E.g. hang the arm over the side of the table Note: - Examiner - subjective - Use of gravity - more accurate
38
What is active-assisted movement?
- Add a bit of passive at the end of an active movement (e.g. When you want to reach full range) - Assist movement throughout
39
What is overpressure?
The full range of motion that the muscle (normal active range) could not bring about Each joint has a passive range of movement which exceeds its available active range (ownself move). To achieive this range, a stretch (push/pressure) is applied to the end of normal active/passive movement
40
Description and Example of normal soft end-feel
Soft tissue approximation E.g. knee flexion (soft tissue of posterior thigh contacting soft tissue of posterior leg)
40
Description and Example of normal firm end-feel
1. Muscular stretch E.g. Hip flexion with knee straight (passive elastic tension of hamstrings muscles) 2. Capsular stretch E.g. Extension of MCP of fingers (tension in anterior capsule) 3. Ligamentous stretch E.g. Forearm supination (tension in palmar radioulnar ligament of inferior radioulnar joint, interosseous mbn, oblique cord)
41
What is end-feel?
How it feels at the end of range
42
Description and Example of normal hard end-feel
Bone contacting bone E.g. Elbow extension (olecranon process of ulna and olecranon fossa of humerus)
43
Description and Example of pathological soft end-feel
Boggy feel; occurring sooner/later in ROM than usual or in joint that is normally firm/hard end-feel E.g. soft tissue oedema; synovitis
44
Description and Example of pathological firm end-feel
Occurring sooner/later in ROM than usual or in a joint that is normally soft/hard end-feel E.g. Inc muscle tonus; capsular, muscular, ligamentous, fascial shortening
45
Description and Example of pathological hard end-feel
Bony grating/bony block, occurring sooner/later in ROM than usual or in a joint that is normally soft/firm end-feel E.g. Chondromalacia, Osteoarthritis, Loose bodies in joint, fracture, myositis. ossificans
46
Description and Example of pathological empty end-feel
No resistance felt. Maybe patient's protective muscle splinting/muscle spasm Lack of end-feel due to pain preventing patient reaching ROM E.g. Acute joint inflammation, Bursitis, Abscess, Fracture, Psychogenic disorder
47
What is a kinematic chain?
Engineering concept used to describe the interconnectedness of movement segments & muscles to describe muscle movements Open & closed chains
48
Open Kinematic Chain (OKC)
Occurs when the distal segment of the chain "moves freely without any external resistance" E.g. Chest press
49
Closed kinematic chain (CKC)
Occurs when the distal segment "meets a 'considerable external resistance' that restrains free motion" Basically exercises done with feet/ hands on the ground or wall / pressing into the wall/ground Feet/hands 'close' the chain E.g. push-up; deadlift
50
What are the types of muscle force generation?
1. Isometric 2. Concentric 3. Eccentric
51
What is isometric muscle force?
Force generation without muscle length changes Basically not lifting or lowering anything E.g. wall squat, planks, bicep curl - hold at the top
52
What is concentric muscle force
Positive work - Force generated through muscle shortening E.g. bicep curl (upwards action; dumbbell going up)
53
What is eccentric muscle force?
Negative work - Force generated through muscle lengthening E.g. bicep curl (downwards action; dumbbell going down)
54
What is the definition of agonists & examples?
Aka prime movers Muscle/muscle group primarily responsible for producing a motion - Actively contracts to produce a concentric/eccentric/isometric contraction E.g. Biceps brachii contracts concentrically to bring about elbow flexion
55
What is the definition of antagonists and examples?
Muscle/muscle group primarily responsible for producing a motion that is directly opposite the intended motion E.g. Triceps brachii is the antagonist of biceps brachii
56
What are the definitions of synergists & the types?
Synergist - Muscle/muscle group that assists the agonist to produce the desired motion Conjoint: provides identical/nearly identical activity to that of agonist Neutralizer: obstructs an unwanted action of the agonist Stabilizer: Stabilises proximal joints for distala joint movement
57
What is the definition of fixators?
Muscle/muscle group that act to stabilise a bone segment in order for the muscle that attaches to it to move the other segment
58
What is physical fitness?
Outcome of Physical activity or exercise
59
What is the difference between physical activity (PA) and exercise?
PA: any bodily movement produced by skeletal muscles that results in energy expenditure; energy expenditure can be measured in kilocalories Exercise: planned, structured and repetitive behaviour that is performed for the purpose of improving/maintaining physical fitness
60
What is muscle strengthening?
- Exercises to inc. muscle strength & muscle endurance - 7 fundamental process principles: progression, regularity, overload, creativity, enjoyment, specificity, supervision Strength: max force the muscle can generate Endurance: time, e.g. reps, how long. you can hold a plank
61
What is muscle re-education?
- Engaging the neuromuscular system to rmb how it work/acts before surgery - Creating new neuronetworks (e.g. in children with cerebral palsy) - provide feedback tot reestablish neuromuscular control/promote ability of muscle/group to contract (functional movements) - Use of electrical stimulators, use of instructions/feedback, manual inputs (e.g. use of hand to adjust/prompt)
62
What is passive insufficiency?
When muscles become elongated over TWO or more joints at the same time - reach state of passive insufficiency Basically muscle 1 is stretched to its max, the lower parts of the muscle cannot stretch anymore
63
What is active insufficiency?
Occurs in multi-joint muscles when the muscle is at its shortest length when its ability to produce physiologic force is minimal Basically, the muscle is contracted to its max, the lower part of the muscle cannot contract anymore
