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 ...
tapping distal phalanx of 3rd or 4th finger elicits flexion of same in thumb Hollenhorst plaque: Robert Hollenhorst: ophthalmology: hypertension, coronary artery disease, and/or diabetes: cholesterol embolus(i) of retinal artery(ies) Homans' sign: John Homans: thrombosis: deep venous thrombosis: knee bent, ankle abruptly dorsiflexed, popliteal pain
Tinel's sign (also Hoffmann-Tinel sign) is a way to detect irritated nerves. It is performed by lightly tapping over the nerve to elicit a sensation of tingling or "pins and needles" in the distribution of the nerve. [1] [2] Percussion is usually performed moving distal to proximal. [2] It is named after Jules Tinel. [3] [4] [5]
H-reflex is analogous to the mechanically induced spinal stretch reflex (for example, knee jerk reflex). "The primary difference between the H-reflex and the spinal stretch reflex is that the H-reflex bypasses the muscle spindle, and, therefore, is a valuable tool in assessing modulation of monosynaptic reflex activity in the spinal cord."
Clonus results due to an increased motor neuron excitation (decreased action potential threshold) and is common in muscles with long conduction delays, such as the long reflex tracts found in distal muscle groups. [1] Clonus is commonly seen in the ankle but may exist in other distal structures as well. [2]
Muscle Loss. IF YOU DROP 15 to 25 percent of your body weight, 15 to 60 percent of that could be lean mass (muscle, bone, anything but fat). Strength training helps counter that. In one study of ...
