The Hoffmann's reflex test itself involves loosely holding the middle finger and flicking the fingernail downward, allowing the middle finger to flick upward reflexively. A positive response is seen when there is flexion and adduction of the thumb on the same hand. [4] Eg. in hypertonia, the tips of other fingers flex and the thumb flexes and ...
Many tendon transfers have been shown to restore opposition to the thumb and provide thumb and finger flexion. In order to have optimal results the individual needs to follow the following principles of tendon transfer: normal tissue equilibrium, movable joints, and a scar-free bed.
This 'pinch-test' exposes the weakness of the flexor pollicis longus muscle and the flexor digitorum profundus I leading to weakness of the flexion of the distal phalanges of the thumb and index finger. This results in impairment of the pincer movement and the patient will have difficulty picking up a small item, such as a coin, from a flat ...
Wartenberg's sign is a neurological sign consisting of involuntary abduction of the fifth (little) finger, caused by unopposed action of the extensor digiti minimi. [ 1 ] [ 2 ] This commonly results from weakness of some of the ulnar nerve innervated intrinsic hand muscles -in particular the palmar interosseous muscle to the little finger ...
Reverse Phalen's test. This test is performed by having the patient maintain full wrist and finger extension for two minutes. The reverse Phalen's test significantly increases pressure in the carpal tunnel within 10 seconds of the change in wrist posture and the carpal tunnel pressure has the tendency to increase throughout the test's duration.
To perform the test, a patient is asked to hold an object, usually a flat object such as a piece of paper, between the thumb and index finger (pinch grip). The examiner then attempts to pull the object out of the subject's hands. [2] A normal individual will be able to maintain a hold on the object without difficulty.
The Bekhterev–Jacobsohn reflex, or Jacobsohn's finger flexion sign, is a clinical sign found in patients with pyramidal tract lesions of the upper limb. In this condition, stroking the dorsum of the forearm, in the area of the distal radius, with the arm supine causes abduction of the hand and flexion of the fingers.
The examiner passively restricts the flexion of the fingers while the examinee attempts to actively flex the thumb. [10] A positive test is marked by restricted active thumb flexion with pain or cramping discomfort in the palmar and radial sides of the distal (lower) forearm or wrist. [ 10 ]
