In upper motor neuron weakness, supination is weaker than pronation in the upper extremity, leading to a pronation of the affected arm. Hart, R. Thumb opposition is graspd by the C8 and T1 nerve roots via the median nerve. Repeat with the other foot. View All Services. Find it on PubMed Spooren, A. Hip flexion is innervated by the L2 and L3 nerve roots hand grasps neuro assessment 2020 the femoral nerve.

Test the strength of wrist extension by asking the patient to extend their wrist while the examiner resists the movement. This tests the forearm extensors. Repeat with the other arm. The wrist extensors are innervated by C6 and C7 nerve roots via the radial nerve. The radial nerve is the "great extensor" of the arm: it innervates all the extensor muscles in the upper and lower arm.

Examine the patient's hands. Look for intrinsic hand, thenar and hypothenar muscle wasting. Test the patient's grip by having the patient hold the examiner's fingers in their fist tightly and instructing them not to let go while the examiner attempts to remove them. Normally the examiner cannot remove their fingers. This tests the forearm flexors and the intrinsic hand muscles. Compare the hands for strength asymmetry.

Finger flexion is innervated by the C8 nerve root via the median nerve. Test the intrinsic hand muscles once again by having Best Hand Plane 2020 the patient abduct or "fan out" all of their fingers.

Instruct the patient to not allow the examiner to compress them back in. Normally, one can resist the examiner from replacing the fingers. Finger abduction or "fanning" is innervated by the T1 nerve root via the ulnar nerve. To complete the motor examination of the upper extremities, test the strength of the thumb opposition by telling the patient to touch the tip of their thumb to the tip of their pinky finger.

Apply resistance to the thumb with your index finger. Repeat with the other thumb and compare. Thumb opposition is innervated by the C8 and T1 nerve roots via the median nerve.

Proceeding to the lower extremities, first test the flexion of the hip by asking the patient to lie down and raise each leg separately while the examiner resists. Repeat and compare with the other leg. This tests the iliopsoas muscles. Hip flexion is innervated by the L2 and L3 nerve roots via the femoral nerve. Test the adduction of the legs by placing your hands on the inner thighs of the patient and asking them to bring both legs together. This tests the adductors of the medial thigh.

Adduction of the hip is mediated by the L2, L3 and L4 nerve roots. Test the abduction of the legs by placing your hands Good Quality Hand Saw 2020 on the outer thighs and asking the patient to move their legs apart. This tests the gluteus maximus and gluteus minimus.

Abduction of the hip is mediated by the L4, L5 and S1 nerve roots. Next, test the extension of the hip by instructing the patient to press down on the examiner's hand which is placed underneath the patient's thigh. Repeat and compare to the other leg. This tests the gluteus maximus. Hip extension is innervated by the L4 and L5 nerve roots via the gluteal nerve.

Test extension at the knee by placing one hand under the knee and the other on top of the lower leg to provide resistance. Ask the patient to "kick out" or extend the lower leg at the knee.

This tests the quadriceps muscle. Knee extension by the quadriceps muscle is innervated by the L3 and L4 nerve roots via the femoral nerve. Test flexion at the knee by holding the knee from the side and applying resistance under the ankle and instructing the patient to pull the lower leg towards their buttock as hard as possible. Repeat with the other leg. This tests the hamstrings. The hamstrings are innervated by the L5 and S1 nerve roots via the sciatic nerve. Test dorsiflexion of the ankle by holding the top of the ankle and have the patient pull their foot up towards their face as hard as possible.

Repeat with the other foot. This tests the muscles in the anterior compartment of the lower leg. Ankle dorsiflexion is innervated by the L4 and L5 nerve roots via the peroneal nerve. Holding the bottom of the foot, ask the patient to "press down on the gas pedal" as hard as possible. Repeat with the other foot and compare.

This tests the gastrocnemius and soleus muscles in the posterior compartment of the lower leg. Ankle plantar flexion is innervated by the S1 and S2 nerve roots via the tibial nerve. To complete the motor exam of the lower extremity ask the patient to move the large toe against the examiner's resistance "up towards the patient's face". The extensor halucis longus muscle is almost completely innervated by the L5 nerve root. Clinical Results.

AbilityLab menu. Last Updated December 27, Purpose The GRT assesses basic unilateral hand performance with manipulating objects with and without a neuroprosthesis in individuals with C5 and C6 tetraplegia. Link to Instrument Instrument Details. Acronym GRT. Assessment Type Performance Measure. Spinal Injuries. Performance-based test Unilateral manipulation of 6 objects representing different weights and sizes 3 with lateral pinch peg, weight, fork and 3 with palmar grasp block, can, videotape Standard sequence of movements for each object grasp, lift and release and for fork grasp depress handle, lift and release Can, paperweight and videotape are placed upright on a box; Block and peg are dropped into a box; fork has different sequence move hand from start position to the fork, grasping and depressing handle to indicator line, releasing handle and returning hand to start position.

Sequence is completed as many times as possible in 30 seconds, for each object. Scored by mean of successful completions and of failures performed in 30 seconds, for each object. Pretest practice permitted until successful trial is completed. If no successful trials for an object, that object was eliminated from the actual test.
