Occupational therapy evaluation and intervention - Deep partial-thickness burns
answer
-Evaluation: same as for superficial partial-thickness burns -Intervention: 1) wound care and debridement, sterile whirlpool, and dressing changes 2) gentle AROM and PROM to individual's tolerance 3) edema control 4) splinting 5) occupational role activities and ADL 6) strengthening (when wounds are healed)
question
Occupational therapy evaluation and intervention - Full thickness burn (requiring grafting)
answer
-Evaluation: 1) ROM (5 to 7 days post-operative) 2) same as for superficial and deep partial-thickness burns -Post-operative intervention: 1) 72 hours: dressing changes, splint at all times 2) five to seven days: begin AROM, light ADL and meaningful activities, sterile whirlpool 3) over seven days: PROM as tolerated, ADL and meaningful activities 4) when wounds are healed, use massage 5) order compression garments 6) provide otoform/elastomer inserts 7) strengthening
question
Antideformit positions following burn injury
answer
-Neck: neutral to slight extension -Chest/abdomen: trunk extension and scapula retraction -Axilla: shoulder abduction 90 degrees and external rotation (airplane splint) -Elbow: extension -Forearm: neutral to supination -Wrist: 30-45 degrees extension -Hand: MCPs 70 degree flexion, IP extension, and thumb abducted -Knee: knee extension, anterior burn, mild flexion -Ankle: 5 degree dorsiflexion
question
Hand splints for burns
answer
-Burns to dorsum of hand: 1) wrist in 30 to 45 degrees extension 2) MCP joints in 70 to 90 degrees flexion 3) IP joints in full extension 4) thumb abducted and extended -Burns to volar surface of hand: 1) wrist in 0 to 30 degrees extension 2) MCP joints in neutral and abducted 3) IP joints in full extension 4) thumb abducted and extended
question
Hypertrophic scars from burns
answer
-Most common with deep second and third degree burns -Appears six to eight weeks after wound closure -One to two years to mature -Compression garments should be worn 24 hours daily: 1) applied when wounds are healed 2) recommendation is to wear 24 hours a day for 1-2 years until scare is matured -Additional intervention include ROM, skin care, ADL, role activities, and patient/family education
question
Pain - Definition
answer
-Personal sensation of hurt that can significantly affect an individual's quality of life
question
Types of pain
answer
-Acute pain has a recent onset and usually lasts for a short duration -Chronic pain is of a long duration and can lead to depression -Myofascial pain is specific to muscles, tendons, or fascia: 1) myofascial pain syndrome (MPS) - persistent, deep aching pains in muscle, nonarticular in origin; characterized by well-defined, highly sensitive tender spots (trigger points) -Fibromyalgia syndrome (FMS) is a musculoskeletal pain and fatigue disorder that can vary in intensity: 1) widespread pain accompanied by tenderness of muscles and adjacent soft tissues 2) nonarticular rheumatic disease of unknown origin -Low back pain: 1) most common work related injury 2) location - lumbar lordosis 3) etiology - a) poor posture = seated and standing b) repetitive bending using poor body mechanics c) heavy lifting d) sleeping with poor posture 4) symptoms - a) pain b) difficulty with self care activities and other role activities (especially lower extremity activities) c) difficulty sleeping
question
Assessment of pain
answer
-Determine location of pain: localized or diffuse -Evaluate intensity of pain: 1) pain intensity scale of 0-10 is most commonly used 2) identify the time of day the pain is most intense -Determine the onset and duration of pain: 1) gradual or sudden onset 2) the length of time pain has been experienced -Description of pain: common descriptors include sharp, throbbing, tender, burning, and shooting -Functional assessment of pain: 1) pain scales that commonly address function (McGill Pain Questionnaire, Pain Disability Index, Functional Intereference Estimate)
question
Occupational therapy intervention for pain
answer
-Utilize physical agent modalities and massage in preparation for functional activities -Teach proper positioning techniques -Splint in the resting position -Gentle ROM -Teach relaxation exercises -Utilize proper body mechanics during self-care, leisure, and work activities -Correct environmental factors -Correct standing and seated postures -Modify activities and provide ADL training and adaptive equipment, as needed -Provide alternative exercise programs (eg. aquatic therapy, Tai-Chi, Aichi)
question
Controls training for body powered prosthetics - Terminal device
answer
-Body motion to activate TD: 1) shoulder glenohumeral flexion on side of TD to be activated 2) scapular abduction (forward roll of shoulder) on side to be activated; bilateral scapular abduction for midline use or with limited strength -Instruction or intervention: therapist manually guides the patient through the motion pattern (note: for AE amputation, keep elbow locked in 90 degrees of flexion and teach TD control only) -Wrist unit rotation: 1) manual prepositioning of TD for supination, pronation or mid-position 2) for unilateral amputation, the TD is rotated in the wrist unit by using the sound hand 3) for bilateral amputation, the TD is rotated by pushing or pulling using the contralateral TD, between the knees, or against a stationary object -Instruction or intervention: the patient must analyze the task and predetermine how to grasp the object to avoid excessive or awkward body movement such as twisting and bending, eg. when carrying a tray, the fingers of the hook must be turned with the hook tips toward the person's midline (body) so the hook is in the mid-position similar to the holding pattern of the sound hand; a jar is held with the finger-tips down (pronated) toward the floor, while the sound arm opens the top
question
Controls training for body powered prosthetics - Elbow unit mechanism
answer
-Body motion to activate elbow lock and unlock -Instruction or intervention: therapist manually guides the patient through these motion patterns; the patient views himself in mirror for visual feedback -Practice motions: 1) scapular depression (push residual limb into socket end) 2) humeral extension/hyperextension 3) humeral abduction -Instruction or intervention: begin with the elbow unit in an unlocked position and the elbow in flexion (arm adducted); the forearm is passively pushed back into extension to lock; listen for "click" sounds; this motion may have to be exaggerated during the initial stages -Practice TD activation with elbow locked -Instruction or intervention: lock elbow; use humeral flexion with scapular abduction to activate TD -Practice elbow flexion and lock at different levels, from full flexion to full extension -Instruction or intervention: unlock elbow and gravity will pull forearm into extension; use humeral flexion to flex elbow at desired height; when locking the elbow unit, flex the elbow slightly higher than desired, which allows for gravity to pull downward as patient locks elbow
question
Controls training for body powered prosthetics - Teach manual control of turntable for internal or external rotation
answer
-Instruction or intervention: unilateral - patient reaches over to rotate upper arm unit -Bilateral - patient pulls or pushes against a stationary object in that environment or with opposite prosthesis
