CATS FINAL Flashcards
(281 cards)
Which movements are included in TMJ Assessment?
- Depression (opening)
- Elevation (closing)
- Protrusion
- Retrusion
- Lateral Deviation of Mandible
What movements can lead to Carpal Tunnel Syndrome and why?
- Repetitive strain, wrist or finger flexion and extension
Which nerve is affected in Carpal Tunnel Syndrome?
- Median
What may cause an increase in pressure within the carpal tunnel?
- Edema
What type of nerve fibres are present in the Median Nerve?
- Sensory, Motor, Autonomic
What conditions may be confused with Carpal Tunnel Syndrome? And how can they be ruled out?
- C6 or C7 nerve root involvement: C6: lateral forearm, thumb and 2nd digit. C7: limited to the 3rd digit and a narrow band down the middle of the Dorsum and volar aspects of the hand just Proximal to the wrist
- Brachial plexus injury: sensory symptoms usually felt along the entire length of the arm, forearm, hand (depends on injury site)
- Median nerve lesion (outside carpal tunnel)
- Cervical nerve root Impingement
- Trigger points
Where is the most common site of injury to the ulnar nerve at the elbow?
- Ulnar Nerve Lesion
- At the cubital tunnel leading to cubital tunnel syndrome
Why are symptoms more likely to occur when the elbow is flexed then when it is extended?
Ulnar Nerve Lesion
- Flexion traction’s the nerve
What is the “downstream principle”? And what are the functional implications of the principle
- Only sensory and/or motor functions distal to the lesion are affected
- Sensory signals arising distal to the lesion do not reach the brain
- Motor signals from the brain do not reach muscles innervated distal to the lesion site
What will occur if lumbricals 3 & 4 are affected?
Ulnar Nerve Lesion
- Finger extension is unopposed -> MCP joints develop a hyperextension deformity
- Known as a “claw-hand”
What are possible signs and symptoms of hemiplegia?
- Paresis/complete paralysis of muscles on the affected side
- Compensatory changes to muscles on the unaffected side
- Paresthesia/anesthesia
- Aphasia-speech impairment
- Visual impairment
- Cognitive impairment: long/short term memory, attention, concentration, desicion-making
- Epilepsy - a possibility with any brain lesion
- Emotional and behavioural changes, e.g, aggression, depression
What are four types of rib articulation?
Intercostal Neuralgia and Rib Subluxation
- Costovertebral
- Costotransverse
- Costochondral
- Sternocostal
What are the possible causes of Median & Ulnar Nerve Lesions?
- Trauma
- Muscle compression
- Decrease in compartment size
What do Median and Ulnar nerves supply?
- Motor and sensory Innervation of the forearm and hand
What deformities may occur with median and Ulnar nerve lesions?
- Median nerve lesion - Ape Hand
- Ulnar nerve lesion - Claw hand
A client experiences motor loss of the following movements:
Erb’s Palsy
- Glenohumeral joint: abduction, external rotation, and forward flexion
- Elbow joint: Flexion
- Forearm: Supination
What other conditions does this shoulder posture make the client susceptible to?
Erb’s Palsy
- Adhesive Capsulitis
- Osteoarthritis
- Subluxation
- Dislocation
What is a compression syndrome?
- A condition arising from pressure exerted upon a Neurovascular bundle by a muscle, or other anatomical structure, causing neurological and/or circulatory signs and symptoms
What general manifestations of neurological impairment?
- Sensory deficits - Paresthesia, pain, and motor dysfunction - muscle weakness
What are general manifestations of vascular impairment?
- Ischemia leading to tropic skin changes and muscle spasms
What are functions of compartments?
- Separate structures
- Link structures that have commonalities
- Facilitate increased force of contraction
- Protection
What might cause increased intra-compartmental mass and what can it lead to?
- Repetitive use: Walking/running on a hard surface - inflammation/edema/Hypertonicity
- Trauma: Blows, bleeding, contusions - pooling of blood in the compartment
- Not stretching before activity: Muscle strains, inflammation/edema
- Fractures, surgery: Inflammation/edema
- Accumulation of intravenous fluid in the compartment: increased mass
What can cause Sciatica
- Shortening of the piriformis muscles - overuse, hypertonicity
- Biomechanical dysfunction such as a leg length discrepancies, pelvic obliquity
- Sacroiliac dysfunction - SI joint sprain
What would you expect to observe with a client with piriformis syndrome?
- Antalgic gait and posture
- Excessive external rotation of the affected leg
- Pelvic obliquity
