Progressive Disorders of the CNS Flashcards
(171 cards)
3 nuclei that make up dorsal or sensorimotor basal ganglia
- caudate nucleus
- putamen
- globus pallidus
BGD Symptoms
- problems with controlling speech, movement, and posture
- difficulty starting, stopping, or sustaining movement
- increased muscle tone and rigidity
- memory loss and trouble finding words
Basal Ganglia Disease (BGD) results in difficulty in
- initiating, continuing, or stopping movement.
- muscle tone (rigidity)
- increased involuntary movements (tremor, chorea)
Motor disorders of BG result in disequilibrium between ___ and ____ movement.
inhibitory and excitatory
Cerebellar dysfunctions: Lesions affect which areas?
Lesions are varied and may affect the Neocerebellar (Posterior lobe), Paleocerebellar (anterior lobe), and Archicerebellar (Flocculonodular lobe).
Cerebellar dysfunctions: Signs & symptoms of neocerebellar lesions (posterior lobe)
Ipsilateral ataxia, Ipsilateral hypotonia & hyporeflexia, Dysmetria, Adiadochkinesia, movement decomposition, asthenia, intention tremors, rebound phenomenon, ataxic gait, staccato voice
Cerebellar dysfunctions: Signs & symptoms of paleocerebellar lesions (anterior lobe)
Disturbances in extensor tone (b/c this lobe receives the Spinocerebellar tracts – which when lost result in an ↑ in extensor tone.)
Cerebellar dysfunctions: Signs & symptoms of archicerebellar lesions (flocculonodular lobe)
Uncoordinated trunk movements – ataxia. Balance deficits d/t loss of vestibular input from vestibular nuclei, cuneocerebellar tract, and rostral cerebellar tract
PT/OT management of cerebellar dysfunctions
Added weight to help decrease tremor (but performance declines due to the added weight); Strengthening (help with deconditioning, weakness, or spasticity)
ALS Basic Info
- destruction of UMN and LMN (degeneration of anterior horn cells and descending corticobulbar and corticospinal)
- usually occurs after 50 yrs but can be younger
- Causes weakness and atrophy to the body
- spasticity, hyperreflexia
- affects distal (limbs) to proximal (whole body)
- loss of voluntary control
- one of 1st signs is thenar eminence wasting
Etiology of ALS
- unknown (viral/autoimmune/toxic)
- 5-10% genetic (autosomal dominant)
Stage I of ALS
early disease, mild focal weakness, asymmetrical distribution, symptoms of hand cramping and fasiculations
Stage II of ALS
moderate weakness in groups of muscles, some wasting (atrophy) of muscles; modified independence with assistive devices
Stage III of ALS
severe weakness of specific muscles, increasing fatigue, mild to moderate functional limitations, ambulatory
Stage IV of ALS
severe weakness and wasting of LEs, mild weakness of UEs; moderate assistive and assistive devices, wheelchair user
Stage V of ALS
progressive weakness with deterioration of mobility and endurance, increased fatigue, moderate to severe weakness of whole limbs and trunk, spasticity, hyperreflexia, loss of head control, maximal assist
Stage VI of ALS
bedridden, dependent ADLs, FMS; progressive respiratory distress, mimics Locked-In Syndrome
Examination of ALS
- pt must have s/s of both UMN and LMN destruction
- determine stage patient is in using ALS Functional Rating Scale
- MMT
- ROM
- Reflexes
- Purdue Pegboard Test
- Pulmonary function
- Speech evaluation
- Ashworth Spasticity scale
- CN’s; especially VII, IX, X, XI, XII
- Gait: timed test
ALS Functional Rating Scale (ALSFRS)
- assess disease progression and function across 10 functional categories
- Scored 0 (loss of function) to 4 (normal function)
- 40 maximal score
Motor Learning Stage 1 of ALS
- independent of mobility and ADLs
- Active ROM
- Cont. normal activities
- stretching of affected joints
- resistive exercises to unaffected mm
- aerobic activities
Motor Learning Stage 2 of ALS
- moderate weakness in groups of mm
- assess for use of assistive devices
- continue stage 1 activities
- increased need for caregiver assistance
- exercise 2-3 times per day with rest in between
Motor Learning Stage 3 of ALS
- continued ambulation but severe weakness in mm groups
- foot drop or hand weakness
- goals is to keep pt physically independent
- use of splints, orthotics
Motor Learning Stage 4 of ALS
- severe weakness of legs, involvement of arms
- WC
- Cont. AROM and PROM to prevent contractures
- strengthening
- integumentary
Motor Learning Stage 5 of ALS
- progressive weakness of mobility and endurance
- inability to transfer
- pain due to cramping and contracture
- stretching, splinting, STM, orthotic
