A portable non-contact tremor vibration measurement and classification apparatus

Tremors are the most common type of movement disorder and affect the lives of those experiencing them. The efficacy of tremor therapies varies according to the aetiology of the tremor and its correct diagnosis. This study develops a portable measurement device capable of noncontact measurement of th...
