A hand-held pressure applicator for treating painful muscle spasms, trigger points, or muscle tension in combination with an electromyographic (EMG) sensor and other possible add-ons, such as a means for applying laser therapy. Manual tactile pressure is applied through the hand-held applicator which is placed directly on the affected area overlaying the problematic muscle spasm or trigger point. Pressure sensors located at the tip of the applicator monitor the amount of tactile pressure administered to the patient. The applicator applies pressure to the affected area while simultaneously monitoring the muscular activity by way of EMG biofeedback. The applicator of the invention provides real time feedback that can be used to adjust the applied pressure, continue at the same level, or conclude the session.
