Quantification of Patellar Tendon Reflex by Motion Analysis

Reflexes assessment is the basic test performed in a neurologic examination, which is an important diagnosis in identifying diseases or lesions in the nervous system [2]. This is because abnormal reflex responses are generally the signs of diseases in the nervous or muscular system [3]. During a particular assessment, reflex of the responding muscle is observed by the examiner and subsequently graded the response base on the examiner’s experience [4]. This in turn leads to variation when a patient is examined by different examiners. Different grading scales are used to grade reflex response at the moment [5], leading to high probability where judgments are conveyed wrongly among medical practitioners.
