Neuromuscular Physical Therapy Practice Patterns Flashcards
A sign is . . .
– Objective findings of pathology
– Can be determined by physical examination
A symptom is . . .
– Subject’s experience of the pathology
– Perceived by the patient
Positive Sign
– Release of abnormal behaviors – Presence of abnormal reflexes – Spasticity
Negative Sign
– Loss of normal behaviors
– Paresis
– Loss of sensation
Primary Effects
– Impairment in the same system as the pathology
– Direct result of pathology
• Paresis, loss of sensation, loss of speech
Secondary Effects
– Impairment in different system from pathology
– Develop as a result of the pathology often over time
• Change in muscle length or decubitus ulcers
Neuromuscular Diseases
– Motor unit
– LMN signs
Disease of Central Motor Control
– Control of the motor unit
– UMN signs
Myalgia signs and symptoms
- Common, but rarely a main complaint
* Onset can be abrupt, slow, or insidious
Myalgias may be due to . . .
– Over-exertion/strain – Metabolic myopathy – Infections – Fibromyalgia – Autoimmune disorders (MS, lupus)
Signs/Symptoms: Weakness
• Rate of progression varies
• Distribution varies
– See Fredericks and Saladin table 12-1
• Complete or partial loss of strength
– Paralysis or plegia indicates complete loss
– Paresis indicates partial loss
Signs/Symptoms: Myasthenia
• Muscle Fatigability
– Performance declines with repeated contractions
– This is not a typical fatigue
Signs/Symptoms: Atrophy
– Myopathy = little atrophy with profound weakness
– Denervation = profound atrophy and weakness
– Cancer = severe atrophy with little weakness
Signs/Symptoms: Hypertrophy
– Unaffected muscles may look relatively larger
– Compensatory hypertrophy due to increased work load of synergistically-related muscles
– Pseudohypertrophy can occur where muscle tissue is replaced with fat and connective tissue
Myogenic Hyperactivity: Fasciculation
Twitch of group of muscle fibers
visible
Myogenic Hyperactivity:
Myokymia
Rippling contraction (visible), especially in the face
Myogenic Hyperactivity: Spasm
Forceful, involuntary contraction
that may interfere with function
Myogenic Hyperactivity: Cramp
Powerful, painful, involuntary spasmodic contraction in single muscle
Myogenic Hyperactivity: Tetany
Sustained spasmodic contraction in multiple muscles
Myogenic Hyperactivity: Fibrillation
Contraction of single muscle fiver (not visible)
Myogenic Hyperactivity: Myotonia
Delayed ability for muscle to relax; alteration in
muscle membrane
Myogenic Hyperactivity: Contracture
Involuntary shortening of fibers in electrically quiet muscle
Signs/Symptoms: Hypotonia
• Reduction in muscle tone that impacts function
– May occur with or without hyporeflexia
– Common in neuromuscular diseases (LMN)
– Feels soft and flabby
– Produces less than normal resistance to stretch
Anesthesia
Loss of sensation, especially pain
Hypoesthesia
Decreased sensitivity to sensation
Paresthesia
Abnormal sensations (burning, prickling, tingling)
Dysesthesia
Unpleasant abnormal sensation produced by innocuous stimuli
Hyperesthesia
Exaggerated unpleasant sensitivity to innocuous stimuli
Hypoalgia
Diminished sensitivity to painful stimuli
Hyperalgia
Excessive sensitivity to painful stimuli
Hyperpathia
Exaggerated unpleasant response to painful stimuli that persists after removal of stimuli
Glove-and- stocking pattern
Forearms distally and mid-calf distally lack sensation (common in neuropathies)
Deep Tendon Reflex Scoring
0 Absent No visible contraction
1+ Hyporeflexia Sluggish contraction with little to no joint movement
2 Normal Slight contraction with slight joint movement
3+ Hyperreflexia Clearly visible, brisk contraction with moderate joint movement
4+ Abnormal 1-3 beats clonus; may spread to contralateral side
5+ Abnormal Sustained clonus; may spread to contralateral side
Central Motor Control Disorders include . . .
– Stroke – SCI – Parkinson’s Disease – TBI – Multiple Sclerosis
Hypertonia: Spasticity
– Velocity dependent increase in muscle tone accompanied
by hyperactive DTR
– Severity varies greatly depending on site and extent of damage
– Predominately in antigravity muscles
– Clasp-knife phenomenon = sustained stretch results in
sudden disappearance of resistance
Hypertonia: Rigidity
– Heightened resistance to passive movement independent of velocity of stretch – Relatively uniform throughout ROM – Most predominant in flexors – Can be lead-pipe or cogwheel
Posturing: Midbrain or bilateral forebrain lesions
– Posturing may be responsive to position, loud
noise, and pain
– Persistence is a poor prognostic indicator
Posturing: Decorticate
blah
Posturing: Decerebrate
blah
Signs/Symptoms: Hypotonia
• Decreased resistance to passive stretch
– Usually associated with diminished DTR
Spinal shock and Diaschisis
– Sudden alteration of function, usually following
injury or insult
– Seen following TBI, CVA, and SCI
Signs/Symptoms: Weakness and Fatigability
Impaired activation of the motor unit ranging from mild to total paralysis
Hemiparesis
• Contralateral = lesion above decussation of pyramidal
tracts
• Ipsilateral = unilateral cerebellar lesion
Quadriparesis
• Supraspinal bilateral lesion
Quadriplegia (tetraplegia)
• SCI T1 or above
Paraplegia (diplegia)
SCI below T1
Loss of Fractionation
Inability to move to a single joint independently of other joints
Abnormal Synergies
– Dominant muscle synergies that emerge when voluntary activation of one joint movement is invariable accompanied by predictable movement at other joints
– Flexion synergy common in UE and extension synergy common in LE
– Know Table 12-6
Coactivation Changes
Agonist and antagonist contract
together during movement
Timing Anomalies
Increased reaction time and movement time
Tremor
Rhythmic oscillating movement occurring at rest or with movement
Dystonia
Powerful, sustained contraction of groups of muscles causing twisting or writhing of whole body; can be fast, slow, or painful
Athetosis
Writhing, twisting movement of limbs, head, trunk, face, or tongue without fixed posture
Associated Reactions
Unintentional movement of one part of the body occurring with intentional movement of another part
Ataxia
Unsteadiness, incoordination, clumsiness; can be halting, jerky, and imprecise movement and difficulty in regulating force, range, direction, velocity, and rhythm of movement
Dysmetria
Error in distance estimation
Dyssynergia
Errors in timing or sequencing resulting in lack of fluidity
Dysdiadochokinesia
Abnormal rhythm and incoordination especially during rapidly alternating movements
Signs/Symptoms: Apraxia
Inability to perform goal-directed movements in absence of motor or sensory dysfunction
Ideomotor Apraxia
- Awkward, clumsy response to understood command
- Unable to use sensory feedback to correct movement
- Lesions typically of premotor area
Ideational Apraxia
- Inability to recognize objects and their uses
- Inability to form appropriate motor program in response to command for habitual movement
- Lesions in dominant hemisphere
Signs/Symptoms: Hypokinesia
Slowness of movement independent of problems with muscle power or coordination
Akinesia
Lack of movement
Bradykinesia
Slowness of movement
Signs/Symptoms: Reflexes
• Superficial (cutaneous)
– Muscle response elicited by stimulation of skin
• Tendon Reflexes
Give the difference between normal plantar reflex and Babinski
- Normal is plantar flexion of toes
- Positive is dorsiflexion of toes with separation and fanning of toes 2-5
- Indicative of pyramidal system damage
Signs/Symptoms: Balance and Sensation
• Balance is reduced through altered motor, reduced reaction and movement time, abnormal tone, and/or poor postural control
• Sensation deficits are related to location and extent of lesion
– Include DCML and Anterolateral systems and their respective sensory modalities
Give the cardinal risk factors for CVA
– Hypertension
– Diabetes
– Heart Disease
Non-modifiable risk factors for CVA
– Age, race, sex, family history, history of CVA
Modifiable risk factors for CVA
– Primary: HTN, DM, hyperlipidemia, hypercholesterolemia,
Chronic inflammatory processes
– Non-primary: inactivity, obesity, smoking, alcohol abuse, drug abuse, oral contraceptives
Warning Signs of CVA
• Sudden numbness or weakness in face, arm, or leg, especially when unilateral
• Sudden confusion, trouble speaking, understanding
• Sudden trouble with vision
• Sudden trouble walking, dizziness, loss of
balance, or incoordination
• Sudden severe headache with no know cause
Transient Ischemic Attacks
• Signs and symptoms last less than 24 hours
– Strong predictor of impending stroke
– Symptoms similar to stroke
• Occasionally, you will see reversible neurologic deficits that last longer than 24 hours but resolve within 3 weeks
Ischemic Stroke Types
– Large artery disease resulting in atherothrombosis
or thromboembolism
– Cardio embolism or embolism of other source
– Lacunar infarcts: small deep infarcts in the distal distribution of penetrating vessels (lenticulostriate, thalamoperforating, pontine perforating arteries, recurrent artery of Heubner). They result from occlusion of one of the small penetrating end arteries at the base of the brain and are due to fibrinoid degeneration.
Ischemic Strokes often occur . . .
During sleep
