Conditions

subjects with trigger points in upper trapezius and levator scapula. Other soft tissue disorders

Interventions

Intervention 1: A low-level Ga-As laser was applied with 5 KHz frequency, a 100 mW point probe (average power), wavelength 905 nm, pulse duration 200 ns, 6 J/cm2 dosages per minute, for 3 minutes dura

Rehabilitation
