muscle length tests Flashcards
(70 cards)
why do muscle length tests assess?
- flexibility and extensibility of muscles which cross a joint
what do muscle length tests help to identify?
- tightness
- restrictions
- asymmetries
what are the two main ankle muscles that can be measured?
- gastrocnemius
- soleus
how do you distinguish between soleus and gastrocnemius?
- knee position
- extended for gastrocnemius vs flexed for soleus
what is the pt starting position when testing gastrocnemius length?
- pt in supine with foot hanging over the end of the plinth
- knee extended
what movement is completed in the gastrocnemius muscle length test?
- passively dorsiflexed by grabbing the calcaneus and allowing the ankle to rest on your hand
what is the pt starting position when testing soleus muscle length?
- pt sits with legs hanging off plinth so knee at 90 degrees
what movement occurs for the soleus length test?
- passively dorsiflex the ankle
what is the WBLT? what is the starting position?
- weight bearing lunge test
- standing knee to wall test
- pt moves forwards in kneeling lunge until knee touches the wall
what needs to stay in contact in the WBLT? what do you do during the test?
- heel needs to always stay in contact with the floor
- foot is moved away from the wall to the point where the knee can only make slight contact with the wall while the heel remains in contact
what is the normal result of the WBLT?
- 10 to 15cm
what are the three main muscle length tests for the knee?
- elys test
- hamstring 90-90 straight leg raise
- back saver sit and reach test
what is the Ely’s test measuring? what is the muscle’s action?
- rectus femoris
- knee extensor
- hip flexor
what is the starting position of the ely’s test? what movement do you complete?
- pt in prone lying
- passively flex the knee maximally using a hand around the ankle
- stabilise the pelvis
when is the ely’s test positive?
- rectus femoris tightness if hip simultaneously flexes with knee flexion
what does the 90-90 striaght leg raise measure? what does this muscle do?
- hamstrings
- knee flexor
- hip extensor
what is the starting position of the 90-90 straight leg raise?
- pt in supine lying
- hip and knees flexed to 90 degrees
what movement occurs in the 90-90 straight leg raise test? how is the pt stabilised?
- pt can stabilise the legs by holding around the back of thighs
- pt asked to extend knee as far as possible
what should the end feel of 90-90 straight leg raise be?
- muscle stretch
when is the 90-90 straight leg raise positive?
- no further than 20 degrees from full extension
what does the backsaver sit and reach test measure?
- hamstrings
what is the starting position of pt in back saver sit and reach test?
- sitting position
- one knee flexed against chest (stabilise pelvis)
- other leg should be extended in front
what is the pt asked to do in the back saver sit and reach test? when is the test positive?
- pt asked to reach forward as far as possible
- positive if pt cannot reach toes
what are the 7 main hip muscle length tests?
- elys test
- thomas test
- obers test
- straight leg raise
- popliteal angle
- gluteus maximus
- adductors/ abductors
