Kinks or non-stationary variations in this curve are observed in certain neurological disorders and preliminary work suggests their relationship to cervical spondylosis. Different methodologies in the time domain and frequency domain have been followed for quantitative analysis of neurological disorders.The present work was taken up to develop an objective method for the identification of...
