Q

Purdue Pegboard (what is it? scoring?)

A

Test of fingertip dexterity and assembly job simulation.
Subtests: 30-second test (right hand, left hand, both hands); one-minute test (assembly).
Scoring: 30-second test is the number of pins placed in the board in 30 seconds. Assmbly is the number of parts assembled during one minute.

Crawford Small Parts Dexterity Test (what is it? scoring?)
Test of fine motor dexterity using small tools (tweezers and screwdriver). Scoring: time to complete assembly
26
Nine Hole Peg Test (what is it? scoring?)
Measures finger dexterity Scoring: time for each hand to place nine pegs in a square board and remove them. (Purdue Pegboard is preferred over the Nine Hole Peg Test because it is unilateral and bilateral, and more reliable.)
27
Jebson Hand Function Test (what is it? subtests? scoring?)
Test of hand function. 7 subtests: writing, simulated page turning, picking up common objects, simulated feeding, stacking, picking up large light objects, picking up large heavy objects. Scoring: time to complete each subject
28
Informal assessment of coordination should include:
- fine motor: observation of routine task performance (examples: handwriting, manipulation of various sized objects, handling money, cutting food, and buttoning) - gross motor: (examples: tossing a ball, reaching into cabinets for specific items, and dressing)
29
what is Codman's exercise?
common form of PROM used for post-surgical shoulder patients (lean over with shoulder hanging and swing shoulder in circles).
30
what are blocking exercises?
used to isolate individual joint motions
31
what is an isometric contraction?
contraction without movement. Contraindicated for patients with hypertension and cardiovascular problems. Can increase BP and HR so they should be avoided.
32
what is an isotonic contraction?
contraction with movement. Eccentric= lengthening Concentric= shortening
33
To increase endurance, work at ___% of maximal resistance or less. Increase ______, not _______.
50% | Increase repetitions/duration, not resistance.
34
Edema reduction techniques
- elevation - manual edema mobilization (special training needed) - retrograde massage * BUT NO manual edema mobilization or retrograde massage with cardiac edema!!! - compression garments - cold packs - contrast bath (immerse hand in warm water, and cold water) - other (not as common): string wrapping, ace bandage wraps, and intermittent compression pump * Heat is contraindicated!!
35
what is Coban wrap?
digit is wrapped distal to proximal to decrease edema in digit. Patient can exercise and use hand for ADLs while wearing Coban.
36
Static splint...
has no resilient components and immobilizes a joint or part
37
Dynamic splint...
includes a resilient component (elastic, rubber band, or spring) which the patient moves. Designed to increase PROM or to augment AROM.
38
Purposes of splinting:
- rest - prevent deformities and contractures - increase joint ROM - protect bone, joint, and soft tissue - increase functional use
39
Hand splinting design standards (2)
Maintain arches of the hand | Do not impinge upon creases of the hand
40
Resting hand splint (functional position!)... give ROM of joints...
- wrist: 20-30 deg extension - MCPs: 30-45 deg flexion - IPs: 0-20 deg flexion ("slight flexion") - thumb abducted ("opposition")
41
Safe position splint (aka intrinsic=plus or anti-deformity splint)... give ROM of joints...
- wrist: 20-30 deg extension (maybe 30-40... but be careful of carpal tunnel canal pressure) - MCPs: 70-90 deg flexion - IPs in extension - thumb abducted and extended
42
Precautions and education for splints
- check patient's skin condition before and after making splint - instruct patient in procedures for splint maintenance and routine skin inspection/care. - ensure patient accepts and understands the purpose, function, and limitations of the splint. - teach proper technique for donning/doffing splint - provide functional training in use of splint in role activities - reevaluate patient's use of splint periodically

62
Common types of Physical Agent Modalities used by entry-level OTs:
- superficial thermal (paraffin, hot packs, fluidotherapy) - superficial cooling agents (cold packs, ice massage) - mechanotherapy (ultrasound, whirlpool) - electrical stimulation units (neuromuscular electrical stimulation; transcutaneous electrical nerve stimulator; high volt galvonic stimulation; iontophoresis).
63
types of heat transfer
- conduction (hot packs, whirlpool, and paraffin) - convection (fluidotherapy) - radiation (laser) - conversion (ultrasound)... heats deeper structures up to 4-5cms
64
benefits of superficial heat therapy
- relieves pain - increases tissue extensibility (increases ROM) - assists with wound healing (increased blood flow) - decreases muscle spasms
65
precautions and contraindications for heat... DO NOT USE WITH:
- postsurgical repairs - acute injuries - impaired sensation - impaired vascular supply
66
benefits of cryotherapy (cold)
- relieves pain - controls edema - decreases abnormal tone - facilitates muscle tone - commonly used to treat acute injuries and post surgical repairs
67
precautions and contraindications for cryotherapy. DO NOT USE WITH:
- sensory deficits including dypersensitivity - impaired circulation - Raynaud's disease
68
benefits of e-stim
- pain control - decreases swelling - stimulates and strengthens muscles - muscle reeducation - stimulates denervated muscle
69
contraindications for e-stim. DO NOT USE WITH:
- cardiac pacemaker - phrenic or urinary bladder stimulators - presence of thrombosis or thrombophlebitis - over carotid sinus
70
Two types of ultrasound: continuous (thermal effects) and pulsed (nonthermal effects). Benefits of each...
Continuous ultrasound... - increases issue extensibility - reduces pain - increases blood flow and tissue permeability - reduces muscle spasms - reaches deeper tissues (up to 5cms) Pulsed ultrasound.... - decreases inflammation - heals tissue
71
Contraindications of ultrasound:
- active malignant tumor - pregnancy - area near pacemaker - some joint replacements (cemented or plastic) - thrombophlebitis - precautions: fractures, growth plates, and breast implants
72
General contraindications for PAMs. DO NOT USE if patient has:
- cancer - pacemaker - pregnancy - cognitive impairment - sensory impairment - vascular impairment - deep vein thrombophlebitis
