Proprioceptive - Deep Tendon Reflex

The effect of elbow position on biceps tendon reflex.

BACKGROUND Testing of tendon (T) reflex is the basic method used in the diagnostic procedure of clinical neurology. Measurement of T reflexes precisely can be a valuable adjunct to clinical examination. Quantification of T reflexes may provide more accurate results. AIMS To analyze the effect of elbow position on biceps T reflex. SETTINGS AND DESIGN A self-controlled clinical trial of bicep...

Influence of Age on Patellar Tendon Reflex Response

BACKGROUND A clinical parameter commonly used to assess the neurological status of an individual is the tendon reflex response. However, the clinical method of evaluation often leads to subjective conclusions that may differ between examiners. Moreover, attempts to quantify the reflex response, especially in older age groups, have produced inconsistent results. This study aims to examine the in...

Delayed tendon reflex (a video demonstration).

This was a classical presentation and the diagnosis was obvious. Her thyroid hormone profile revealed a thyroidstimulating hormone level of 151.79 μIU (normal 0.35–5.50) along with a total T3 of 0.31 ng/ml (normal 0.60–1.81) and total T4 of 1.00 (normal 5.60–13.70). In an excellent review of the delayed tendon reflex it has been shown that the rate of muscle relaxation depends on the rate of ca...

Conditioning of H reflex by a preceding subthreshold tendon reflex stimulus.

The soleus H reflex excitability cycle has been studied using, as conditioning stimulus, a mechanical tap, subthreshold for the tendon reflex, which was applied either on the Achilles tendon, the short biceps tendon, or the quadriceps tendon. In all cases there was an early facilitation followed by a longlasting inhibition of the test H reflex. The same results were obtained in patients with a ...
