Spray Stretch Technique Versus Sustain Pressure for Trapezius Triggers

"Group A receive spray and stretch technique (Ethyl chloride) with conventional treatment.~The upper trapezius muscle stretches on the basis of the Technique originally described by Simons. The subject is seated in a relaxed position on their homolateral hand for anchoring the distal end of the studied muscle. Initially, 3 to 5 parallel sweeps of ethyl chloride spray is applied covering the Upper trapezius muscle. Then, the muscle are positioned in a maximal but tolerable stretch and lengthened until the Physical Therapist felt the muscle tension barrier. This procedure repeated 2 or 3 times."

"Group B receive sustain pressure release with conventional treatment. Progressive pressure release are considered in two stages. The initial step is to recognize and find the trigger in upper fiber of trapezius, utilizing trigger point palpation. Trigger point felt as firm and restricted hyperirritable knots with in gut of the muscle.~The second step is to applying pressure release ranging from eight to twelve second for each pressure, then it increases gradually for maximum of twenty seconds. The total duration of pressure is five minutes or more until the discharge is felt by the fingers."
