25
arches of the hand
transverse arch curves from radial to the ulnar side of the hand longitudinal arch from wrist to fingers
26
wrist and hand mobility
prolonged hold/joint mobilization increase ROM promoting capsular mobility distal carpal row is immobile while mobility occurs at proximal carpal row
27
intrinsic hand muscles
(18) muscles that begin and end within the hand Intrinsics are stabilizers and balance motions Lumbricals flex MCP joints and extend IP joints
28
intrinsic plus and minus
Intrinsic plus: immobilize the hand into a safe position for healing Approximately 60-90 degrees flexion Intrinsic minus: making a claw Extensor digitorum hyperextends the MCP joints and simultaneously flexes the IPs with profundus Happens when interossei and lumbricals are not working
29
extrinsic hand muscles
(18 tendons) muscles that terminate in the hand but have muscle bellies in the forearm they cross the wrist and flex and extend the digits
30
mobile rays of hand
thumb, ring, and small digit metacarpals
31
fixed rays of hand
index and long fingers metacarpals
32
flexor tendon pulley system
annual pulleys and cruciate ligaments prevent the extrinsic digit flexor tendons from bowstringing annular pulleys (5) in each finger A1-A5 → prevent bowstringing 3 cruciate ligaments (C1-C3) prevents outer sheath from collapsing positioned around the flexor digitorum profundus and superficialis
33
extensor mechanism (mx and function)
lumbricals, interossei, and extensor communis function: to safely extend digits, provide shortcuts for extensor tendons across joints, permits full flexion 3 bands: 2 lateral and 1 central
34
primary wrist flexors
flexor carpi ulnaris and radialis
35
primary wrist extensors
extensor carpi ulnaris, extensor carpi radialis longus and brevis
36
measures for intrinsic tightness
Bunnell test: if the mcp is extended and you do passive pip flexion and it’s limited, but if you switch to flexion for both and it’s better that tells you there is intrinsic tightness (table top) positive test finding for PIP restriction: increased PIP flexion with MCP flexion (implies intrinsic restriction) full PIP flexion with MCP extension is a normal test finding
37
measures for extrinsic tightness
digit extension increases as wrist moves towards flexion, or digit flexion increases as the wrist moves towards extension due to tightness at extrinsic wrist flexors hold a fist, extend their wrist and then have them drop out of their fist and if they have trouble with it, they have issues with extrinsic extensor tightness
38
grip strength
Measure on dynamometer | 3 times and take average
39
pinch strength
Chuck pinch – two fingers on top, thumb on bottom Lateral pinch – a scissor grasp with the thumb on top and lateral border of the index finger on the bottom Tip to tip – tip of index on top, tip of thumb on bottom
40
edema measures
Skin creases Volumetric Putting hand in water to measure difference in water volume Girth/circumference
41
peripheral v nerve root injuries
Peripheral nerve injury: decreased sensation in the peripheral pattern; decreased strength in specific peripheral nerve muscle innervations Nerve root injury: dermatomal patterns of decreased sensation; myotome patterns of decreased strength
42
sunderland 1st degree
disruption: intact axon and preserved structures prognosis: full recovery in days to week therapy: short term, focused tx: observe, conservative
43
Sunderland 2nd degree
disruption: disrupted axon with intact endoneurium prognosis: variable recovery, worse with proximal injuries therapy: short term/moderate tx: surgical or conservative intervention
44
sunderland 3rd degree
disruption: endometrium disrupted with perineum intact prognosis: 60-80 recovery, incomplete therapy: moderate tx: surgical may be required
45
sunderland 4th degree
disruption: endometrium and perineurium disrupted and epineuruem intact prognosis: nerve grating required therapy: long term comprehensive tx: surgical intervention
46
sunderland 5th degree
disruption: loss of nerve trunk continuity, complete disorganization/transection prognosis: nerve grating required therapy: long term comprehensive tx: surgical intervention
47
capsular patterns and related conditions
predicted loss of motion; limited movement in a joint specific ratio Arthritis: inflammation when the entire capsule is involved glenohumeral: more limited ER, abduction, IR (In order) elbow: more limited flexion distal radioulnar: full ROM with pain at extreme ends wrist: flex/ext limited
48
non capsular patterns
Limitation of ROM that do not involve the entire capsule/joint ex) ligament adhesions gleno: acute deltoid bursitis elbow: internal derangement wrist: subluxated capitate bone
49
clinical reasoning process
initial referral → additional information → check: occupational profile performance, occupational tasks, activities, component performance → problem definition → patient and OT understanding roles → treatment selection → treatment → reevaluating → treatment modification → discharge planning → treatment termination
50
ADL
bathing, showering, toileting, dressing, eating, feeding, functional mobility, personal hygiene and grooming, sexual activity
51
IADL
care of others, pets, children, communication management, driving and community mobility, financial management, home establishment and management, meal prep and cleanup, religious and spiritual activities and expression, safety and emergency maintenance, shopping
52
spinal curves
2 Primary Curves: Thoracic & Sacral / Posterior convexity / Kyphosis 2 Secondary Curves: Cervical & Lumbar / Anterior convexity / Lordosis
53
common causes of lumbar pain
spinal stenosis and fractures !!! others: spondylosis: nerve root compression spondylolysis: fracture of lumbar vertebrae spondylolisthesis: vertebrae slippage stenosis: narrowing of spinal canal
54
herniation: protrusion
nucleus protrudes into ruptured inner fibers of annulus; peripheral fibers intact but a general bulging of the disc occurs
55
herniation: extrusion
nucleus penetrates outer walls of the annulus, but the protruding tissue is still connected to the central portion of the disc
56
herniation: sequestration
posterior longitudinal ligament is ruptured, and one or more fragments of the herniated material protrude in the spinal cord
57
herniation: schmorl's node
rupture of the disc through the cartilaginous end plate due to a congenital weakness
58
pelvic-spinal movement
anterior pelvic tilt = spinal extension posterior pelvic tilt = spinal flexion lateral pelvic tilt = scapular elevation in rhythm with the lower side of the pelvis = scapular depression in rhythm with the higher side of the pelvis
59
spinal-scapular movement
extension of spine = adduction of scapula | flexion of spine = abduction of scapula
60
scapulo-humeral movement
adduction of scapula = external rotation of humerus abduction of scapula = internal rotation of humerus upward rotation of scapula = humeral flexion/abduction downward rotation of scapula = humeral extension/adduction
61
Identify the order of muscle return following a median nerve surgical repair (proximal to distal innervated muscles)
median nerve is medial side of the biceps tendon, proximal to carpal tunnel the muscles most proximal to the lesion will return first and that muscle’s motion will be first as well motor return continues proximal to distal - superficial volar forearm (pronator teres, FCR, palmares longus), intermediate group (FDS), deep group
62
contraindications for performing AROM
- many types of tissue injury and/or treatment - cardiac status precautions: pain, cognition, movement into end range
63
benefits of AROM
- maintain tissue length, increase circulation, proprioception - decrease rate of atrophy
64
benefits of PROM
- preserves soft tissue length - prevents contractures - allows tissue gliding
65
median nerve injury
will not be able to oppose thumb or flex radial 3 fingers, pinky and ring finger will be flexed (ape hand)
66
ulnar nerve injury
will not be able to extend 4th & 5th digits, index & middle will be extended (“claw hand”) - crossed finger sign, froment's, duchenne, claw
67
radial nerve injury
wrist drop
68
tenodesis
starts with relaxed digits and wrist flexion, active wrist extension results in the digits flexing due to passive insufficiency
69
hutchinson's fracture
(chauffeur's) | radial styloid fracture
70
distal radius fracture phases
phase I: edema and pain control, not moving, some passive movement phase II: edema control, restore ROM to AROM in wrist, light ADL phase II: passive stretching, some resistance, strengthening wrist
71
most common UE fracture
distal radius
72
slipped disk
doesn’t actually slip, vertebra can slide forward due to excessive shear forces
73
Tangential strain (disc)
posterior fibers of annulus are stretched to a point of damage (deformation); strain is without tearing
74
strains vs sprains
Strains: pulling of ligamentous, capsular, or tendinosis structure without tearing Sprains: tearing or excessive stretching with microscopic contusion (bruising) or hemorrhage or both
75
types of bone in the vertebral column and their function
Trabeculae (spongy) bone supports weight Covered with cortical bone thickened around the rim where the epiphyseal plates located in the center by the cartilaginous end plate
76
proximal phalanx fracture tx phases
Phase I: edema control, immobilize Phase II: AROM, scar message, gliding exercises Phase III: PROM and progressive resistance
77
middle phalanx fracture tx phases
same as proximal phalanx EXCEPT: - special attention to DIP joint function - phase II emphasis on FDP blocking and gliding phase III flexing into therapy putty, dynamic splinting
78
greatest risk for rupture of disk
