Biomechanical Exam Flashcards
(28 cards)
Functional Motion for Extremities:
Ask the patient to perform essential ADLs
-i.e. reaching, walking, partial squat, heel raise, single limb stance, etc. per scan
If essential ADLs are WNL and more investigation is needed, ask the patient to perform ________ ADLs
-example:
higher level; lifting, throwing, jumoing, or running per scan
-Postions pareint to apply a gliding motion gently and passively along with joint sifrace
-Observe quantity and quality of motion, partially the end feel and including facial responses.
-Determines P! and point of limitation relationship
Accessory Motion Testing
What is normal Accessory Motion Testing?
appropriate gliding with firm end feel; no P!, click clunk or spasm
If Accessory Motion Testing has limited gliding and firm end feel; consistent limitation with ROM then that indicates:
Hypomobility- reduced accessory motion; intra-articular restriction
If Accessory Motion Testing has click, clunk, spasm; later, softer and/or empty end feel; may be more than expected glding with limited ROM then that indicates:
Hypermobility- excessive accessory motion-extra-articular restriction
If Provocative Test is abnormal then that indicates:
involved tissue based on symptoms per test
What is a normal Stability Test when stress is applied?
No symptoms, laxity, m. guarding with normal end feel
If Stability Test has immediate symptoms click, clunk, spasm; later soft and/or empty end feel when stress is applied then that indicates?
Acute condition
If no immediate symptoms when performing the stability test you should:
hold for 10 sec, like with stress tests
If Stability Test is abnormal when you hold for 10 sec. you should repeat it with:
M. activation, CPP, corrected posture, and/or external support.
If Stability Test (w/10sec hold) is repeated and pt. has improved symptoms, motion activation, and or function then that indicates:
normal - need for stabilization
If Stability Test (w/10sec hold) is repeated and pt. NO has improved symptoms, motion activation, and or function then that indicates:
abnormal- worse case of instability
M.length test had limited motion then which indicates:
abnormal- shortened muscle
Following biomechanical exams initially positions the pt. in the mid-range position and away from any painful position.
-Instructs the patient “don’t let me move you”
-Apply smooth, exponentially increasing, and appropriate resistance on the distal segment of the joint being tested for 3 sec.
MMT
If MMT is 0-4/5 grades per biomechanics course****
If MMT is only painful in the lengthed range then that indicated:
grade I contractile strain
When restest of MMT was performed; pt. had improved P!/function then that indicates:
Inhibited m./regional interdependence
When restest of MMT was performed; pt. had fatiguing weakness then that indicates:
decreased nerve conduction
When restest of MMT was performed; pt. had consistent weakness that indicates:
deconditioned/persistent contractile rupture
When restest of MMT was performed; pt. had worse
When restest of MMT was performed; pt. had worse P!/function then that indicates:
severe/acute condition
Which of the following Biomechanical Exams asses for activation endurance through palpation, observation, and use of either test for specific muscles typically a local muscle.
Muscle Activation & Endurance
What is a normal Muscle Activation and Endurance Test?
Good activation and control with 20 reps and 20 sec holds for local muscles.
