reflex is a misnomer, why tendons move when tapped, where to assess DTRs, and how to assess them to obtain valid and reliable information. The testing of DTRs, although common, can serve as a powerful tool to estimate magnesium levels and indirect-ly indicate changing magnesium levels in the patient.

Reticular reflex myoclonus: a physiological type of humanpost-hypoxic myoclonus M. HALLETT,' D. CHADWICK, JANE ADAM, ANDC. D. MARSDEN2 Fromthe University DepartmentofNeurology, King'sCollegeHospitalMedicalSchool, andInstitute ofPsychiatry, London SUMMARY Apatientwithpost-hypoxicmyoclonus,sensitivetotherapywith5-hydroxytryptophan Clonus may be found at the ankle, patella, triceps surae, wrist, jaw, biceps brachii. In general, clonus may occur in any muscle with a frequency of 5-8 Hz and the average period of oscillations of the ankle clonus is approximately 160-200 ms. Plantar flexion (PF) comprises 45% of the period, dorsifleksion (DF) comprises 55% of the period. of clonus frequency are length of reflex arc; the frequency of clonus can increase with the decre-ase in activation latency of la afferent fibers; fac-tors such as the mass and viscosity of the muscles can affect the frequency of clonus by changing the activity latency of spindle relaxation (21).

Clonus is a rhythmic, oscillating, stretch reflex, the cause of which is not totally known; however, it relates to lesions in upper motor neurons and therefore is generally accompanied by hyperreflexia. Therefore, clonus is used as part of the neurological physical exam to evaluate the status of a patient’s nervous system.

They usually check for it in your ankles, though it can be seen elsewhere. With Preeclampsia it is caused by central nervous system involvement (as is hyperreflexia). The main symptom of clonus is involuntary muscle spasms. These muscle spasms can be sudden, shock-like, intensive, and frequent. Clonus may affect only one muscle or several muscles, and it can If you have a hyperactive reflex don’t forget to look for clonus.

Deep tendon (muscle stretch) reflex testing evaluates afferent nerves, synaptic connections within the spinal cord, motor nerves, and descending motor pathways. Lower motor neuron lesions (eg, affecting the anterior horn cell, spinal root, or peripheral nerve) depress reflexes; upper motor neuron lesions (ie, non–basal ganglia disorders anywhere above the anterior horn cell) increase reflexes. The ankle jerk reflex, also known as the Achilles reflex, occurs when the Achilles tendon is tapped while the foot is dorsiflexed.It is a type of stretch reflex that tests the function of the gastrocnemius muscle and the nerve that supplies it.

Each time the muscle relaxes from the previous reflex contraction, the applied stretching force renews the reflex, setting up a rhythmic series of muscle contractions that continue as long as the tension is applied. The reflex exam is fundamental to the neurological exam and important to locating upper versus lower motor neuron lesions. There are five deep tendon reflexes and a number of superficial and visceral reflexes covered here. This video is an example of the abnormal, rhythmic reflex known as clonus.
