Influence of age on patellar tendon reflex response.

<h4>Background</h4>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 r...

Forty healthy subjects were selected and categorized into three different age groups. Patellar reflexes were elicited from both the left and right patellar tendons of each subject at three different tapping angles and using the Jendrassik maneuver. The findings suggested that age has a significant effect on the magnitude of the reflex response. An angle of 45° may be the ideal tapping angle at which the reflex can be elicited to detect age-related differences in reflex response. The reflex responses were also not influenced by gender and were observed to be fairly symmetrical.<h4>Conclusions/significance</h4>Neurologically normal individuals will experience an age-dependent decline in patellar reflex response.Annapoorna ChandrasekharNoor Azuan Abu OsmanLai Kuan ThamKheng Seang LimWan Abu Bakar Wan AbasPublic Library of Science (PLoS)articleMedicineRScienceQENPLoS ONE, Vol 8, Iss 11, p e80799 (2013)
