Q

Biomechanical Approach

A

Focuses on ROM, strength & endurance req to perform na occ; most commonly used to tx patients w LMN deficits & othro probs. Should NOT be used in isolation, most effected when paired with other approaches that focus on engagement. Settings most commonly seen: hand clinics, work programs, phys med & rehab depts & ergo programs

Nine Hole Peg Test
Finger Dexterity; each hand places 9 pegs in square board and then removes - Purdue is preferred
26
Jebson Hand Fx Test
7 subtests: writing, sim page turning, picking up common objects, sim feeding, stacking, picking up large light & heavy objects
27
Informal Assessment of Coordination Should Include
FM: handwriting, manipulation, money handling, cutting foods & buttons; GM: tossing ball, reaching in cabinets, dressing
28
Passive ROM
Moving the joint to the desired range using ex force. Can be performed by therapist gently moving extremity. Passive stretching is PROM w overpressure. MUST review physicans orders. Heat prior helps ROM.
29
Codmans Ex
Pendulum exercises akaCodman's exercises are intended to be a passive motion of the shoulder. The momentum of the movement of the body should be the driving force for the gentle swinging of the arm -PROM
30
Active ROM
Should be performed when PROM is greater than ROM. Tendon gliding exercises. Blocking ex: used to isolate individual joint motion. Emp fx'al use.
31
Increasing Strength
High resistance, low reps. Isometrics & isotonics
32
Isometrics
contraction w/o mvmt - sometimes can produce more forceful contraction & are contraindicated for ppl w HTN, cardiovas probs since can increase HR/BP
33
Isotonics
Contraction w movement. Eccentric - lengthening & Concentric - shortening Utilized when move limbs: curls - slight more force to initiate contraction but force does not change while contracting
34
Increasing Endurance
Work at 50% of max resistance or less. Increase reps/duration, not resistance - e con methods
35
Decreasing edema
Elevation, retrograde massage, manual edema mobilization (special training), compression garments (coband for digits dist to prox), cold pack (elevate too) - heat contraindicated
36
Scar Mngt
ROM: early mobilization is most effective. Massage: circles/friction. Compression. Scar pad w compression. Splinting to prevent contractures. Edema control, esp in acute phase.
37
Sensory Training
Desensitization/re-edu: (begin in periphery of scar) massage, textures, vibrations, 3-phase desensitization kit & fluido therapy.
38
Increasing Coordination
Bring w GM then to FM. Choose act where ROM is in reach but challenging. Focus on accuracy/speed beginning w gross/slow.
39
E-con & Work Simplification Principles
Plan short rest periods during activities. Schedule & balance light/heavy. Avoid multiple trips and use equipment if needed. Elim non-essential tasks. Delegation. Sit for counter-top work. Organize cabinets so freq used objects are easy to reach. AE & electrical appliances. Slide rather than lift heavy objects. Rest before/after work.
40
Joint Protection Principles
Maintain joint ROM/mus strength by using max ROM/strength during daily acts. Use strongest/largest joints for task completion - knees/hip for lifting, push rather than pull, lift w both hands. Avoid holding joints in 1 position/deformity positions for extended periods. Use AE.
41
Body Mechanics Principle
Do not move objects that are too heavy, ask for help. Slide or push object rather than lift. Directly face object that is about to be lifted. Keep object close to the body while lifting & hold at waist level. Feet flat and maintain firm/broad base of support. Bend at knees/hips not waist w back as straight as possible. Breathe while lifting. Lift by straightening legs. Move slowly & do not rotate trunk. Lower body to level of work.
42
Static vs Dynamic Splint
S: no resilient components & immobilizes a joint or part. D: Includes resilient component (elastic, rubberband or spring) which the individual moves > designed to increase PROM or increase ROM
43
Splinting purposes
Rest, prevent deformities/contractures, increase joint ROM, protect bone, joint & soft tissue & increase fx'al use.
44
Hand Splinting Design Standards
Maintain arches of hand: prox, transverse & longitudinal. Do not impinge upon hand creases: dis/prox palmar, dis/prox wrist & thenar.
45
Mechanical Principles of Splinting
Decrease pressure: wide/long splint base is most desirable w rounded edges. Sling applied w 90 angel of pull. Use low load to increase duration. Avoid position of deformity: wrist flex, MCP hyperexten, IP joint flex, thumb adducted.
46
Resting Hand Splint: Fx'al Position
Wrist: 20-30 ex., MCP: 30-45 flex., IPs: 0-20 flex & Thumb abducted.
47
Safe Position Splint (intrinsic plus or anti-deformity splint)
Wrist: 20-40 ex., MCPs: 70-90 flex, IPs in exten & thumb abducted/extended
48
Splinting Precautions
Check skin integrity before and after. Instruct/edu on wear procedures. Provide fx'al training in use for fx'al acts. Re-eval use
49

72
Types of hear transfer
Conduction: hot packs, whirlpool, paraffin (1cm). Convection: fluidotherapy. Radiation: laser. Conversion: ultrasound - heats deeper structures (4-5cm)
73
Benefits vs Precautions w Heat
B: relieves pain, increases tissue extensibilty, assists w wound healing by increasing blood flow & decreases musc spasm. P: postsug repairs, acute injuries, impaired sensation & impaired vascular supply.
74
Hot Packs
Check skin prior/after. Check temp: 165F is standard. 4 layers over heat pack. Check skin every 5min. Hot pack removed after 20min
75
Paraffin
Check skin prior/after. Check temp: 125-130F is standard. Wash/thoroughly dry. Dip/pull out 8-12x, then wrap hand in cellophane and cover w towel.
76
Fluidotherapy

78
Benefits vs Precautions of Cryotherapy
B: Relieves pain, controls edema, decreases abnorm tone, facilitates muscle tone & commonly used for post surg/acute injuries. P: no w sensory defs, impaired circulation or raynauds.
79
Ice Pack
Check skin prior and after. Apply towel (dry/wet) between skin and cold pack. Check skin after 3-5min - 10min tx; Ice massage is directly to skin for 3-5min
80

B: pain control, decreased swell, stim/strengthens muscle, muscle re-edu & stim denervated mus. C: cardiac pacemaker, phrenic/unirary bladder stims, presence of thrombosis/thrombophlebitis or over carotid sinus.
81
Ultrasound
Continuous (thermal) or pulsed (non-thermal). Benefits of continuous: increased tissue extensibility, pain reduction, increased blood flow and tissue permiability, reduces muscle spasms & reaches deeper. Benefits of pulse: decrease inflam /heal tissue.
