isometric muscle tests Flashcards
what do strength tests allow you to assess?
- functional capabilities of a muscle
what do muscle strength tests help identify? why is this beneficial?
- helps identify muscle imbalances
- which can be the cause of injury
what does it also help to evaluate?
- post surgery
- recovery
what are the two isometric tests of the talocrural joint?
- Plantarflexion
- dorsiflexion
how do you isometrically test plantarflexion?
- in supine, pt brought into 90 degrees of flexion
- fixate above the ankle
- apply resistance at the sole of the foot and ask pt to resist
how do you isometrically test dorsiflexion?
- pt in supine with leg in 90 degrees of flexion
- fixate above the ankle
- apply downward force pressure on the dorsum of the foot
what are the two isometric tests you can perform at the subtalar joint?
- inversion
- eversion
how do you isometrically test inversion?
- pt in supine with leg extended
- fixate the humerus and grab onto sole of foot on medial side
- pt moves sole inwards against resistance
how do you isometrically measure eversion?
- pt in supine with leg extended
- fixate the tibia on the dorsal side
- other hand on the lateral side of the foot with fingers on the sole
- ask pt to bring the sole outward against inwards resistance
what are the two isometric muscle tests that can be performed at the knee?
- extension
- flexion
how can you isometrically test extension of the knee?
- pt in supine
- put arm under closest leg and through to other leg where it rests on patella
- use other hand wrapped around ankle to resist extension by trying to flex the leg
how do you isometrically test knee flexion?
- pt in supine
- flex the knee to 30 degrees
- stabilise underneath of femur
- using the other hand wrapped around the ankle joint with the fingers underneath apply resistance pushing the leg into extension
what are the 6 isometric muscle tests for the hip?
- flexion
- extension
- abduction
- adduction
- external rotation
- internal rotation
how do you isometrically test hip flexion?
- pt in supine with legs extended and hip in 60 degrees of flexion
- hold onto anterior femur above knee and just above the ankle joint
- ask pt to try to flex the hip while you resist into extension
how do you isometrically test hip extension?
- pt in supine with legs extended
- bring the leg into 30 degrees of flexion
- one hand wrapped around medial aspect of thigh and other around lateral ankle
- apply flexion resistance
how do you isometrically test hip adduction?
- pt in supine with legs extended
- place one hand on inner thigh and inner lower leg (above ankle)
- ask pt to try push towards over leg against resistance
how do you isometrically test hip abduction?
- pt in supine with legs extended
- place one hand on outer thigh and one hand on outer lower leg
- ask pt to push leg outwards towards you
how do you isometrically test hip internal rotation?
- pt in supine
- flex hip to 90 degrees with one hand above the knee and the other wrapped around the ankle
- ask pt to move the ankle outwards while you resist
how do you isometrically test hip external rotation?
- pt in supine
- flex hip to 90 degrees with one hand on medial thigh and the other wrapped over the top of the ankle with the fingers positioned medially
- ask pt to move the ankle inwards while you resist
what are the 6 isometric tests of the shoulder joint?
- flexion
- extension
- abduction
- adduction
- external rotation
- internal rotation
how do you isometrically test shoulder flexion?
- pt in sitting with arm in scapular plane
- fixate above the elbow at the back
- push down on the elbow at the front with the other hand
how do you isometrically test shoulder extension?
- pt in sitting with arm in scapular plane
- fixate above the elbow
- apply resistance on the lateral side of the lower arm just above the wrist joint
- push forwards
how do you isometrically test shoulder abduction?
- pt in sitting with arm in scapular plane
- one hand underneath the elbow
- other hand on top of the elbow
- resistance in adduction direction
how do you isometrically test shoulder adduction?
- pt in sitting with arm in scapular plane
- one hand underneath the elbow
- other hand on top of the elbow
- using the bottom hand, resist in abduction direction
how do you isometrically test shoulder external rotation?
- pt in sitting position with elbow flexed to 90 degrees and close to the body
- ask pt to push their forearm out
- with one hand stabilise the elbow while the other resist ER at the wrist on the lateral side
how do you isometrically test shoulder internal rotation?
- pt in sitting with elbow flexed to 90 degrees and wrist in neutral
- one hand stabilises elbow
- other hand placed on medial arm
- resistance applied upwards
what are the four isometric tests of the elbow?
- flexion
- extension
- supination
- pronation
how do you isometrically test elbow flexion?
- pt in sitting with elbow flexed to 90 degrees
- one hand stabilises the elbow
- other hand over the top of the lower arm just above the wrist
- instruct pt to bring arm towards chest and apply downwards resistance
how do you isometrically test elbow extension?
-Pt in sitting with elbow flexed to 90 degrees
-One hand stabilises the elbow
-Other hand on the underneath of the lower arm (below wrist)
-Ask pt to try move arm down against upwards resistance
how do you isometrically test elbow supination?
-Pt in sitting with elbow flexed to 90 degrees
-Start with wrist in neutral position (mid pronation/ supination)
-One arm stabilises the arm on the underneath side below elbow
-Other arm above wrist joint
how do you isometrically test elbow pronation?
-Pt in sitting with elbow flexed to 90 degrees
-Start with wrist in neutral position (mid pronation/ supination)
-One arm underneath the lower arm below the elbow
-Other arm above the wrist joint
what are the 4 isometric tests of the wrist?
- flexion
- extension
- radial deviation
- ulnar deviation
how do you isometrically test wrist flexion?
-Pt in sitting with forearm resting on the plinth with elbow flexed
-Fixate distal forearm
- Apply upwards resistance on their palm
how do you isometrically test wrist extension?
-Pt in sitting with forearm resting on the plinth with elbow flexed
- Fixate distal forearm
- Apply downwards resistance on the dorsum of the hand
how do you isometrically test radial deviation?
- Pt in sitting with forearm resting on the plinth with elbow flexed
- Pt asked to make a fist
- Fixate distal forearm
- Apply resistance over the dorsum of their hand towards thumb
how do you isometrically test ulnar deviation?
- Pt in sitting with forearm resting on the plinth with elbow flexed
- Pt asked to make a fist
- Fixate distal forearm
- Apply resistance over the dorsum of their hand
