Biomechanical Exam

Question 1

Functional Motion for Extremities:

Answer 1

Ask the patient to perform essential ADLs
-i.e. reaching, walking, partial squat, heel raise, single limb stance, etc. per scan

Question 2

If essential ADLs are WNL and more investigation is needed, ask the patient to perform ________ ADLs
-example:

Answer 2

higher level; lifting, throwing, jumoing, or running per scan

Question 3

-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

Answer 3

Accessory Motion Testing

Question 4

What is normal Accessory Motion Testing?

Answer 4

appropriate gliding with firm end feel; no P!, click clunk or spasm

Question 5

If Accessory Motion Testing has limited gliding and firm end feel; consistent limitation with ROM then that indicates:

Answer 5

Hypomobility- reduced accessory motion; intra-articular restriction

Question 6

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:

Answer 6

Hypermobility- excessive accessory motion-extra-articular restriction

Question 7

If Provocative Test is abnormal then that indicates:

Answer 7

involved tissue based on symptoms per test

Question 8

What is a normal Stability Test when stress is applied?

Answer 8

No symptoms, laxity, m. guarding with normal end feel

Question 9

If Stability Test has immediate symptoms click, clunk, spasm; later soft and/or empty end feel when stress is applied then that indicates?

Answer 9

Acute condition

Question 10

If no immediate symptoms when performing the stability test you should:

Answer 10

hold for 10 sec, like with stress tests

Question 11

If Stability Test is abnormal when you hold for 10 sec. you should repeat it with:

Answer 11

M. activation, CPP, corrected posture, and/or external support.

Question 12

If Stability Test (w/10sec hold) is repeated and pt. has improved symptoms, motion activation, and or function then that indicates:

Answer 12

normal - need for stabilization

Question 13

If Stability Test (w/10sec hold) is repeated and pt. NO has improved symptoms, motion activation, and or function then that indicates:

Answer 13

abnormal- worse case of instability

Question 14

M.length test had limited motion then which indicates:

Answer 14

abnormal- shortened muscle

Question 15

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.

Answer 15

MMT

Question 16

If MMT is 0-4/5 grades per biomechanics course****

Question 17

If MMT is only painful in the lengthed range then that indicated:

Answer 17

grade I contractile strain

Question 18

When restest of MMT was performed; pt. had improved P!/function then that indicates:

Answer 18

Inhibited m./regional interdependence

Question 19

When restest of MMT was performed; pt. had fatiguing weakness then that indicates:

Answer 19

decreased nerve conduction

Question 20

When restest of MMT was performed; pt. had consistent weakness that indicates:

Answer 20

deconditioned/persistent contractile rupture

Question 21

When restest of MMT was performed; pt. had worse

Question 22

When restest of MMT was performed; pt. had worse P!/function then that indicates:

Answer 22

severe/acute condition

Question 23

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.

Answer 23

Muscle Activation & Endurance

Question 24

What is a normal Muscle Activation and Endurance Test?

Answer 24

Good activation and control with 20 reps and 20 sec holds for local muscles.

Question 25

If Muscles Activation and Endurance Test has poor activation and control with < 20 reps or > 20 sec holds; global m. compensation then that indicates:

Answer 25

inhibited

Question 26

When should we test the O-C2 Accessory Motion Upper Cervical Region

Answer 26

When Rot. < 60

Question 27

Two options for the O-C1 joint:

Answer 27

1. Limited rot with an anterior nod (ipsilateral restriction)
2. Limited rot with a posterior nod (contralateral restriction)
