title: Role of temporalis muscle over activity in chronic tension type headache: effect of yoga based management.
abstract: The role of central versus peripheral mechanisms has always been questioned while explaining the etiopathogenesis of chronic tension type headache (CTTH). The following study was done to study the role of muscle spasm in CTTH. 15 patients of CTTH and 7 age matched controls were included in the study and their m. temporalis EMG was recorded for one minute each during rest, mental activity and maximal voluntary contraction and subjective pain scoring was done by visual analogue scale. The results revealed significant overactivity of m.temporalis in CTTH patients at rest when compared with control subjects (P = 0.01 and 0.03 left and right side respectively). After respective interventions namely non steroidal anti inflammatory drugs, botulinum toxin injections and yogic life style course, the EMG records revealed decrease in the mean EMG amplitude of m. temporalis during rest and mental activity more significantly after yoga based interventions (P = 0.03) and subjective pain scores decreased from 7.00 +/- 2.10 to 2.00 +/- 1.26 (P = 0.02) supporting the beneficial effect of such non invasive techniques.
