Muscle grading-- Complete range of motion against gravity with full resistance
|
5/5 Normal
|
|
Muscle grading--Complete range of motion against gravity with some resistance
|
4/5 Good
|
|
Muscle grading -- Complete range of motion against gravity - enough strength to put joint through normal range of motion
|
3/5 Fair
|
|
Muscle grading-- Complete range of motion with gravity eliminated. This can be done by turning the patient on a side so they do not have to overcome the pull of gravity.
|
2/5 Poor
|
|
Muscle grading -- No evidence of slight contraction but no joint motion. The doctor can feel the muscle contract but there is no joint motion.
|
1/5 Trace
|
|
Muscle grading -- No evidence of contraction
|
0/5 No evidence of contraction
|
|
An increased muscular resistance felt by the examiner during quick joint movement, which then quickly fades away ("clasped knife"). In most clinical circumstances have associated cortical or pyramidal pathway lesions (Upper Motor neuron lesion).
|
Spasticity
|
|
Tension at first, followed by a decrease in that tension as the joint opens.
|
Clasped knife
|
|
An involuntary muscular resistance felt when moving a resting joint and persists as the joint is moved through its entire range of motion. The mechanism for this may be related to muscle spindle mechanism interference from diseased extrapyramidal structures (UMNL)
|
Rigidity
|
|
Usually indicative of neurological damage at the level of the reflex arc (LMNL), cerebellar disease may cause diffuse form
|
Hypotonia (decreased muscle tone)
|
|
A phenomenon that is in no way related to vascular shock, May occur following acute, severe upper motor neuron damage, in either the brain (cerebral shock) or the spinal cord (spinal shock). The unique finding is that a suddenly occurring and severe UMNL, which would typically cause central nervous system findings, first cause only peripheral type neurological findings.
|
Neural Shock
|
|
Loss of normal neurological function: reductions in muscle tone, muscle stretch reflexes, muscle strength and muscle volume. LMNL produce only this.
|
Deficit phenomena
|
|
Exaggerations or perversions of normal neurological function and are due to a loss of cortical inhibition. Hyper-reflexia, hypertonia and pathological reflexes would be this.
|
Release phenomena (named due to the release from descending cortical inhibition.)

|
Reflex Grading System (Wexler Scale) -- Identify what 0, +1, +2, +3, +4 are

0=Absent with reinforcement
+1 = Hypoactive with reinforcement +2 = Normal +3 = Hyperactive +4 = Hyperactive with transient (or sustained) clonus |
|
Describe exam procedure to assess deep tendon reflexes
|
Position the patient correctly to assure they are relaxed and have their eyes closed and looking away. Strike the reflex tendon, if nothing reposition and try again. If nothing still, try Jendrassik maneuver (distraction). Look for speed of reaction grade, vigor of response and length of contraction.
|
|
Describe how to perform Reinforcement (Jendrassik maneuver)
|
On performing the patellar reflex (for example) the patient is asked to hook his fingers and try to pull them apart at the time the reflex is being tested. Reinforcement can be done a number of ways by distracting the patient while performing the reflex. If using reinforcement, add an R to the grade (ie +1R)
|
|
A continued involuntary rapid flexion and extension of a muscle while a joint is under sustained resistance. It is due to a rapid-fire elicitation of the stretch muscle reflexes. May be present at the wrist (extension) knee and ankle.

Involuntary movements of the face, mouth, tongue and limbs. Onset usually months after prolonged use of neuroleptic agents. (neuroleptic agents are drugs given for psychotic disorders). The largest single category of involuntary movement.
|
Tardive dyskinesias
|
|
Characteristic of posterior column disease and results from loss of proprioception in extremities. Patients walk with a wide base, slapping feet and usually watching their feet so they know where they are.
|
Tabetic or Ataxic gait -- in the dark or with their eyes closed, the ataxia is much worse.
|
|
Affected leg is rigid and swung from the hip in a semicircle; the patient leans to the affected side and the arm on that side is held in a rigid, semiflexed position.
|
Hemiplegic gait (brain lesion UMNL resulting in paralysis of the opposite side of the body)
|
|
Characteristic of spastic paraplegia. The legs are adducted, crossing alternately in front of one another with the knees scraping together. The resulting steps are short and progression slow.
|
Scissors gait
|
|
As seen in acute alcoholism may result from drug poisoning, multiple neuritis, brain tumors, multiple sclerosis or general paresis.

Drunken or staggering gait
|
|
Results from dislocated hips or muscular dystrophies with weakness of the hips. In either case, the trunk muscles are drawn into play, so that the patient rolls from side to side.
|
Waddling or clumsy gait
|
|
Characterized by high knee action and flopping of the feet (or foot). Even when the leg is raised the toes tend to drag along the floor. Occurs with paralysis of the anterior tibial group of muscles, as in alcoholic neuritis, peroneal nerve injury, poliomyelitis and progressive muscular atrophy.
|
Steppage Gait (foot drop)
|
|
Characterized by marked irregularity and unsteadiness associated with vertigo and a tendency to reel to one side. Lower extremities appear loose; movement of the advancing limb starts slowly, but the limb is unexpectedly and vigorously flung forward and lands with a stamp on the floor. Gait is wide-based, irregular, reeling or deviated with staggering on turning.
|
Cerebellar gait or ataxia (not looking down as in Tabetic or ataxic gait)
|
|
Characterized by a forward-leaning posture and short, shuffling steps, beginning slowly at first and becoming more rapid ("marche a petits pas"). Patients with the classic features of parkinsonism have a stooped posture, take short steps, and frequently accelerate rapidly, so that they appear to be chasing their center of gravity.
|
Propulsion or Festination gait
|
|
Simulate various paralyses (e.g. monoplegias, hemiplegias, or paraplegias)but differ from the organic forms in being more pronounced and complete, with the ability to use the limb in emergencies. The gait is apt to be bizarre or fantastic, characterized by exaggerated balancing motions and inconsistency between the gait shown and the patient's actual ability to move the limb voluntarily.
|
Hysterical gait (non-organic, psychological)
|
|
a form of hysterical ataxia with such bizarre incoordination that the patient is unable to stand or walk, yet all leg movements can be performed normally while the patient is sitting or is in bed.
|
Astasia-Abasia
|
|
When pain is produced by weight-bearing on a lower extremity, the patient puts the affected limb down carefully and takes a short step to get the weight off the painful limb as soon as possible. The good limb is brought forward rapidly and lands vigorously on the floor.
|
