Term
This dz is chronic, progressive, but not terminal
Definition
CMT
Term
This dz is acute and largely reversible in most cases.
Definition
Guillian Barre
Term
This dz affects both UMN and LMN and variations of both: Only LMN, only UMN, or primarily cranial nerves.
Definition
ALS
Term
This dz results in weakness, increased spasticity and stiffness, hyperreflexia. Fasciculations may be the first symptom. The largest and most heavily myelinated nerves are usually the first to be affected.
Definition
ALS
Term
This dz results in destruction of UMN and LMN as well as destruction of anterior horn cells of the spinal cord causing death and replacement with scar tissue. It causes sclerosis of the lateral spinal cord and is characterized by muscle wasting and increased tone.

Term
When a person with ALS is first diagnosed they may be in Stage 1 of rehabilitation. What does this entail?
Definition
Ambulatory, Independent in ADLs, mild weakness and ms cramps, fatigue of weakened muscles.
TX: ROM, strengthening, functional activities, medications, psychological support.

-Do gross and functional strengthening. Do not isolate ms groups because that will cause too much fatigue

Definition
Stage 3
Term
What does stage 4 of ALS rehabiliation look like?
Definition

Definition
If they do not have a power w/c
Term
One of the most common acquired neuropathies. Also called Acute Idiopathic Polyneuritis, or Landry's Ascending Paralysis. It is the most common acute dz causing paralysis in developed countries.
Definition
GBS
Term
This is sometimes confused with Chronic Inflammatory Demyelinating Polyradical Neuropathy where pt may experience periods of worsening and improvement with relapses.
Definition
GBS
Term
This dz progresses rapidly or may cause paralysis and/or respiratory arrest in hours. May continue to progress over 1-2 weeks then plateu. Full recover may occur although many have some remaining disability. 10% experience chronic dz. This is NOT hereditary.
Definition
GBS
Term
The cause is unknown for this dz and it has no preference to young, old, male, or female. 60% have a history of UTI, mumps, flu, mono, etc. 85% are ambulatory within 6 months. 5% mortality rate due to rapid onset of respiratory problems.
Definition
GBS
Term
Name some common diagnostic features of GBS.
Definition
-Motor weakness
-Mild sensory deficits

-Absence of fever at onset
-May have increased CSF
-Nerve conduction velocities are abnl
-Recovery begins 2-4 weeks after plateu
Term
May see abnormal sweating. Need to monitor vitals closely. First symptom may be tingling or numbness in fingers and toes then progress proximally. May be uni or bilateral.

Definition
Prognosis of GBS
Term
Name 3 factors that affect prognosis in GBS.
Definition
1. Rapid onset and progression to quadriplegia
2. Respiratory dependence
3. Failure to show improvement within 3 weeks of plateau
Term
How do you medically manage GBS?
Definition
Respiratory compromise should be closely monitored as well as cardiac complications. Drug Rx: plasma exchange, IVIG (intravenous immunoglobin)
Term
Describe the PT evaluation in GBS pts.
Definition
-Motor Eval - only ms specific to function, do not fatigue pt
-Use of pain scale - pts will tend to be hypersensitive
-Respiratory and dysphagia eval - speech therapy but we may need to help via positioning
-Functional assessment
-Sensory assessment - specific areas
-Autonomic system monitor (BP, HR, bowel and bladder)
-EMG testing
Term
Name some treatments done on GBS pts
Definition
-ROM
-Massage to help with pain and hypersensitivity
-Strengthening/sitting program - recline w/c with jay/roho cusion. Do this ASAP b/c of respiratory fxn
-Active exercise - gross motor only
-Functional activities -concentrate on proximal ms because recover is proximal to distal
-Equipment assessment, transportation
-Family training
Term
How should you progress ROM in GBS pts
Definition
PROM initially then AAROM and AROM if the pt can perform full ROM without pain or fatigue
Term
Strength returns proximal to distal in GBS pts, what is the therapy goal related to this?
Definition
Maintain the ms in a "ready" state, prevent overwork and pace recovery process to obtain max function. Exercise should be directed to functional strength. Reps should be low and rest periods high
Term
Describe the sitting program for GBS pts
Definition
Gradual sitting program should be established as the axial musculature may be fatigued even with supportive sitting
Term
What are some long term exercise precautions for GBS pts?
Definition
May need to limit fatiguing exercises for up to 1 year. Some pt's continue to show deficits during strenuous exercise that requires max endurance and may have difficulty returning to work or activities that require max effort. Pt fatiguing could cause relapse
Term
The most common hereditary neuropathy. Also called Peroneal Muscular Atrophy. Set of inherited peripheral neuropathies that severely range widely in the same family. Onset is usually ~ 20 years old.
Definition
CMT
Term
Effects both motor and sensory. Death may be due to respiratory or secondary complications. Does not occur any more in men or women
Definition
CMT
Term
Ppl with this dz may unknowingly carry the recessive genes. They may only discover their true gene history too late and have already passed it onto their children. It affects 60-70% of family members.
Definition
CMT
Term
It is rare, but it may be caused by a spontaneous gene mutation. It is linked to defective genes on chromosome 1, 17 and X. 60-70% are inherited in a dominant pattern. Female = male. Rare recessive genes tends to be the most severe cases. Diagnosed by blood, genetic testing.
Definition
CMT
Term
Name some common characteristics of CMT.
Definition
-Muscle wasting
-Pt may not be able to distinguish hot from cold
-Loss of DTR's
-Bone and joint deformities (pt may trip a lot) (high arches - pes cavus, hammer toes, foot drop)
-Can progress to distal UEs (loss of fine motor, may effect quads but more rare, may need hand splints, inability to hold grasp things)
-Initially below the knee ms wasting then progresses to below elbow
Term
This dz can cause arrhythmias so be careful when exercising. It can also cause speech deficits, respiratory complications in severe cases, and the initial symptoms may appear as falls, inability to pick up toes, ankle instability and deficits in static stance, visible atrophy of ms, fatigue, and the inability to stoop, knee, climb, or run due to decreased LE sensation.
Definition
CMT
Term
Medications are available for this disease but they may cause regression or make symptoms worse. They are scientifically documented as being toxic and in some cases dangerous for these pts. Common meds are zoloft, stantins, dilantin, etc.
