Examination Of The Motor System (handout based) Flashcards
(34 cards)
steadiness and verticality of the standing posture
Station
Initial inspection of Body Contours, Posture and Gait
- Motor examination begins the moment the patient walks into your clinic
- Have the patient undress
- Determine the patient’s gestalt, somatotype or body build
- Inspect the size and contour of muscles
Walking is also known as
Gait
muscles are strongest when tested from the shortest position
Length - strength principle
muscles which support the standing posture against collapse by pull of gravity
Anti - gravity muscle principle
Grading of strength testing
0 - No contraction
1 - A flicker or trace of contraction
2 - Active movement with gravity eliminated
3 - Active movement against gravity
4 - Active movement againstgravity and moderate resistance
5 - Normal power
Muscular resistance apart from gravity or joint disease the examiner feels when manipulating a patient’s resting joint
Muscle Tone
Muscle tone is due to:
- Elasticity of the muscle
* Number and rate of motor discharges
Initial catch or resistance and then a yielding when the examiner manipulates the patient’s resting extremity
Spasticity
Increased muscular resistance felt throughout the entire range of movement when the examiner slowly manipulates a patient’s resting joint
Rigidity
Resistance equal in degree and range that the patient presents to the examiner as he tries to move a part in any direction
Paratonia
Decreased resistance
Flaccidity
Increased range of motion of the joint movement (i.e hyperextensible knees or flaccid heel cords)
Flaccidity
Grading of MSR (muscle stretch reflex)
0 - Areflexia
1 - Hyporeflexia
2 and 3 - Normal
4 and 4+ - Hypereflexia
Superficial (plantar) Reflexes: Move an object along the lateral side of the foot
chaddock
Superficial (plantar) Reflexes: Squeeze hard on the Achilles tendon
Schaeffer
Superficial (plantar) Reflexes: Press your knuckles on the patient’s shin and move them down
Oppenheim
Superficial (plantar) Reflexes: Squeeze the calf muscles momentarily
Gordon
Superficial (plantar) Reflexes: Make multiple light pinpricks on the dorsolateral surface of the foot
Bing
Superficial (plantar) Reflexes: Pull on the 4thtoe outward and downward for a brief time and release suddenly
Gonda, Stransky
Paralyzes movements in hemiplegic, quadriplegic distribution, not individual muscles
UMN Lesion
Atrophy of disuse
UMN Lesion
Hyperactive MSRs; (+)Clonus, Clasp-knife spasticity; (+) Extensor Toe Sign
UMN Lesion
Paralyzes individual muscles or sets of muscles in root or peripheral nerve distribution
LMN Lesion
