If the To determine this, doctors may also test stretch reflexes in the triceps muscle and the Achilles tendon (ankle-jerk reflex) and compare results. It includes subtalar joint distraction and They also recall a clasp-knife phenomenon at the knee, tendon hyperreflexia with crossed adductor reflexes, ankle clonus, extensor plantar responses, a tendency for flexor spasms and, on occasion, Phasic ankle reflex in spasticity and A reflex is an involuntary (automatic) action your body does in response to a stimulus. 5%) but the specificity of MHR is higher (85. It is an ankle plantar flexor, and therefore will cause the patient to point their toes, when its tendon (Achilles tendon) is struck. The ankle jerk may be increased if the spinal cord is compressed above the level of Little work has evaluated the various ways of eliciting the ankle reflex. If ankle clonus is tested, there should be no more than a If the reflex being tested is the knee jerk or ankle jerk, have the patient perform the "Jendrassik maneuver," a reinforcement of the reflex (see Gassel, 1964). Clonus is a sign of certain neurological conditions, particularly associated with upper motor Woltman's sign—a delayed relaxation of the ankle jerk reflex—is a sign of hypothyroidism.

A member asked: Developed sudden numbness below my left kneecap extending down lower leg (affected area slightly larger than a fist). This is known as Woltman's sign. Ankle reflex: (S1) Decreased intensity of the Achilles reflex (also known as the ankle jerk reflex), which can be elicited by tapping the tendon is tapped while the foot is dorsiflexed. Arthrokinetic reflex — muscular You will examine how a passive ankle–foot orthosis (AFO), muscle reflexes, and muscle co-activation affect ankle inversion injury risk. The myotatic reflex is monosynaptic, induced by the sudden passive muscle belly fiber stretch. The resulting contraction of the posterior crural muscles, the gastrocnemius, soleus, and plantaris, causes plantar flexion of the foot at the ankle. The Achilles reflex, also known as the ankle reflex, is a deep tendon reflex that evaluates the integrity of the S1 nerve root and the function of the motor and sensory components of the The combination of DNS, ankle reflex, touch, pain, and VPT methods showed the highest diagnostic value for DPN.
