Week 11 to Week 14 Flashcards
Supports & Subluxation :
What are reasons for prescription for slings/supports?
Weakness, subluxation, hypotonia, pain, neglect, decreased cognition, Pain and subluxation for orthoses
Supports & Subluxation :
Reasons for discontinued use:
Improvement in strength
Summarize Article Continued (Foongchomcheay, Ada, & Canning, 2005):
Summary:
Supportive devices commonly prescribed by Australian physiotherapists to prevent subluxation
Slings most commonly prescribed
Wheelchair/chair attachments also widely used
Strapping also common
Best for preventing subluxation: Lab tray, arm trough, triangular sling, and Harris sling (sling for standing only/temporary)
Taping for Subluxation:
Taping Overview
Beneficial for shoulder impingement, joint sprains, and multi-directional instability
Reposition humeral head with tape to that it is in a neutral position
Taping allows client to feel normal alignment
Can result in immediate pain relief and improved ROM
Taping for Subluxation:
Article: (Peters & Lee, 2003)
Case study of shoulder taping on individual with R hemiplegic UE following CVA
Taping significantly reduced pain and relieved tension
Taping method: tri pull method = 3 pieces of tape
1) Mid humerus deltoid tuberosity across the scapula near T3 spinous process
2) Deltoid tuberosity across clavicle to mid clavicle
3) Deltoid tuberosity over acromion process to the neck
Outcome measures:
Results:
CA tri pull method
position
1) Medial = 1 inch below deltoid tuberosity - 1 inch above acromial process
2) Posterior = 1 inch below deltoid tuberosity - 1 inch above spine of scapula
3) Anterior = 1 inch below deltoid tuberosity - 1 inch above coracoid process
E-stim & Subluxation
May improve muscle strength, joint alignment, spasticity, and sensory deficits
Rationale = allows muscle activity to maintain the glenohumeral joint
No significant evidence of pain reduction with e-stim, did improve pain free PROM
No negative effects found
Functional e-stim found to be effective in reducing shldr subluxation. Most effective early on
Orthotics: Principles
Orthotics: Principles
Used to maintain or increase the length of soft tissues by preventing or lengthening shortened tissues and preventing overstretching of the antagonist
Used to correct biomechanical malalignment and protecting joint integrity
Used to position the hand to assist in functional tasks
Used to promote independence in specific areas of occupation
Compensate for weakness by providing an external support
Limited Evidence
Evidence currently does not support one style of orthosis over another
(Gillen, 2016)
Considerations for Prescribing & Designing Orthotics
Spasticity
Orthosis may prevent painful contractures and loss of tissue length
Serve to provide a stretch to the distal UE
TX should begin before spasticity becomes severe
Those with severe spasticity should not use Orthosis - Why?
Considerations for Prescribing & Designing Orthotics: Soft Tissue Shortening
Evaluate Extrinsics:
Extend the wrist with digits flexed, wrist in ext. and attempt to extend the digits
Next flex the wrist palm upwards
Evaluate Intrinsics:
Normal: MCP are flexed and IP joints are extended
Normal: MCP are extended and IP are flexed
Hold MCP joint in ext and attempt to flex the PIP joint
Extrinsic extensor tightness:
full passive composite wrist and digit flexion is not obtainable.
Extrinsic flexor tightness:
full passive composite wrist and digit extension is not obtainable.
Intrinsic tightness:
PIPs & DIPs can be fully passively flexed when MCP’s are in a position of flexion (puts the interossei on slack)
PIPs & DIPs cannot be fully passively flexed when MCP’s are in a position of extension
Considerations for Prescribing & Designing Orthotics
Low Load Prolonged Stress (LLPS)
LLPS in when the tissue is held in a low lengthened position for a total end range time (TERT).
TERT = 1-2 hrs, 3 -4 hours, ideally progresses to 6 - 8 hrs
Stretching manually is not enough and must be followed up with orthotic devices
Orthotic must be readjusted (weekly) to ensure prolonged stretch is occurring
Orthotics: Application Consideration: Normal Posture of the Distal UE
Forearm neutral (midway between supination and pronation)
Wrist 10 - 15 degrees of ext
Thumb slight ext and abd, MCP and IP flexxed 15 - 20 degrees
2nd metacarpal aligned w/ radius
Digits: all joints in slight (10-20 degrees) flexion
Palmar arch maintained
Orthotics: Application Consideration: Typical Deviations after Stroke
Wrist Flexion =
Wrist Flexion = flattened palmer arches passive digit extension shortened collateral ligaments @ MPs narrowed thumb web space decreased grip decreased wrist deviation ROM Edema shortening of wrist & extrinsic digit flexors lengthening of wrist & extrinsic digit extensors
Orthotics: Application Consideration: Typical Deviations after Stroke
Wrist & digit flexion
shortened extrinsic flexors lengthened extrinsic extensors decreased normal tenodesis action contractures and deformity skin maceration risk
Orthotics: Application Consideration: Typical Deviations after Stroke
Extreme ulnar deviation
decreased wrist /
shortened tissues ulnar FA
lengthened tissues radial FA
shift of carpal rows
Orthotics: Application Consideration: Typical Deviations after Stroke
Loss of palmar arches
decreased grip
decreased dexterity
TBI
The most common cause of death and disability among young people
TBI: Open
penetrating injury or perforating
Injury depends on shape, mass, direction, and velocity of the object
TBI: Closed
Closed direct or indirect impact without penetration
TBI: Blast injuries =
= can occur in conjunction with open or closed
Pathology: Focal
Caused by a direct blow to the head with an external object or fall, penetrating injury from a weapon, collision of the brain with the inner tables of the skull
Common findings from falls = intracerebral and brain surface contusions (inferior and dorsal-lateral frontal lobes, anterior and medial temporal lobes, and less common inferior cerebellum)
Pathology: Diffuse vs. Focal:
Focal
Caused by a direct blow to the head with an external object or fall, penetrating injury from a weapon, collision of the brain with the inner tables of the skull

Pathology: Diffuse vs. Focal:
Coup
(the site of direct injury)
Pathology: Diffuse vs. Focal:
Countercoup
(site of indirect injury)
Epidural hematomas (EDHs
associated with skull fractures and disruption of meningeal arteries
Subdural hematomas (SDHs) =
occur between the dura and brain surface due to tearing of bridging veins
Location of trauma dictates symptoms:
Pre-frontal & anterior temporal areas: impaired memory, emotion and motivation
Orbitofrontal area: impulsivity
Frontolateral cortex:impassivity, hemiparesis, impaired attention and mental flexibility
Multifocal & Diffuse Brain injury
Often caused by sudden deceleration of the body and head with variable forces and deeper portions of the brain
Intracerebral hemorrhage (ICH)
nearly always present with missile wounds and common after falls and assault
Subarachnoid hemorrhage (SAH) & Intraventricular hemorrhage (IVH)
occur when the pia or arachnoid is torn.
Diffuse axonal injuries (DAIs)/ Traumatic axonal injury (TAI) =
= prototypic lesions caused by rapid deceleration and rotation of the brain in the skull
Possible symptoms include:
Ataxia Diplopia Dysarthria Impulsivity, irritability Apathy, poor initiative Decreased mental processing speed & efficiency Impaired attention Impaired abstract reasoning, planning, problem solving
Primary injury =
= occurs at the time of trauma
Secondary injury=
Occur as a result of the effects of brain swelling in a closed space, loss of perfusion, and decreased delivery of oxygen
The American Association of Neurological Surgeons has developed guidelines for management of severe TBI to minimize secondary injury
Resuscitation of blood pressure and oxygenation, management of elevated intracranial pressure, nutrition after acute trauma and seizure prophylaxis
Secondary effects (Radomski, 2008): hypoxia, hypotension, hypothermia, and hyperthermia (most common)
State of Consciousness
TBI typically results in an altered level of consciousness
From Coma to conscious awareness
Progression along this continuum varies depending on age, previous health, severity of injury, and medical/therapeutic/environmental management.
Coma =
As coma resolves client is either partially aware (minimally conscious) or if no awareness = vegetative
Vegetative State =
- Wakefulness without awareness
- Characteristics: no awareness of self or environment, inability to interact with others, no sustained or voluntary behavioral responses, no language comprehension, sleep wake cycle varies, ability to regulate temp, breathing, and circulation with medical care, incontinence of bowels and bladder, variably preserved cranial nerves and spinal reflexes
Minimally Conscious State (MCS)
- Evidence of awareness of self and/or environment.
- Must have 1 of the following: ability to follow commands, gesture or verbal yes/no responses, intelligible verbalization, and purposeful movement
Post Traumatic Amnesia (PTA)
- Single best measurable predictor of functional outcomes
- Length of time from the injury to the moment the individual regains ongoing memory of daily events
- Longer PTA = poorer outcomes (cognitive and motor abilities, and function)
Intracranial Pressure
When the brain is injured, it reacts like other parts of the body that may be injured…it swells.
Unfortunately, the cranial vault where the brain sits inside the skull has a limited volume of about 1,400 milliliters.
When the brain swells, it can damage and kill neurons by squeezing them and stopping oxygen from reaching the cells.
If the (ICP) pressure gets too much, the brain can be forced into the hole at the base of the brain, the foramen magnum, and compress the brainstem.
The brain stem is where the consciousness, breathing, and heart rate are controlled.
Damage here can result in coma or death.
Second Impact Syndrome (SIS)
Occurs when an individual suffers a second head injury before the initial injury has fully healed…leads to diffuse cerebral swelling
Can potentially result in death within minutes
Rare enough condition that its frequency of occurrence is debated

Chronic Traumatic Encephalopathy
A neurodegenerative disease associated with repeated head trauma
Results in generalized global atrophy of the brain, ventricular dilation, thinning of the corpus collosum, and neurofibrillary bundles similar to AD
Symptoms include headaches, difficulties with attention and memory, mood disorders, motor dysfunction, and dementia
First identified in 1954 and linked to boxing, it has gained more attention in recent years due to the suicides of NFL football players and a recent movie about Dr. Bennet Omalu
Decerebrate rigidity =
humans results from a midbrain lesion and is manifested by an exaggerated extensor posture of all extremities.
Decorticate rigidity =
Decorticate posture is an abnormal posturing in which a person is stiff with bent arms, clenched fists, and legs held out straight. … This type of posturing is a sign of severe damage in the brain
Retrograde amnesia =
s a loss of memory-access to events that occurred, or information that was learned, before an injury or the onset of a disease.
Anterograde amnesia =
Anterograde amnesia is a loss of the ability to create new memories after the event that caused amnesia, leading to a partial or complete inability to recall the recent past, while long-term memories from before the event remain intact.
Symptoms: Visual & Perceptual:
