Brief Summary:
The aim of this research is to determine the effects of spray and stretch technique versus sustain pressure for the management of upper trapezius triggers. A randomized control trail is conducting at Khyber Teaching Hospital Peshawar and Northwest General Hospital and Research center Peshawar. The sample size is 54. The Participants divide into two groups, 27 participants in Group A (receive the spray and stretch technique) and 27 in Group B (receive sustain pressure). The study duration is 6 months. Purposive non probability sampling technique applied. Only 20 to 35 years participants with upper trapezius trigger is including in this trial. Tools use in this study are visual analogue scale (VAS), Neck Disability Index (NDI), Hospital Anxiety and Depression Scale (HADS), Goniometer, Algometer and Manual muscle strength (MMT). Data analyzed through SPSS version 25.

Arm Intervention/treatment
Experimental: Group A
Spray and Stretch technique Conventional treatment Hot pack (10-15 min) Stretching (3 sets of 10 repetitions with 10 seconds hold) AROM exercises (3 sets of 10 repetition)
Combination Product: Spray and Stretch technique (Ethyl chloride)

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.

Active Comparator: Group B
Sustain pressure release Conventional treatment Hot pack (10-15 min) Stretching (3 sets of 10 repetitions with 10 seconds hold) AROM exercises (3 sets of 10 repetition)
Other: Sustain pressure release

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.

Primary Outcome Measures :
  1. Neck disability index [ Time Frame: 2 weeks ]
    Changes from base line Northwick disability index was developed first in Northwick Park hospital, England. It was designed to measure the neck pain and disability over time. It consists of 10, five parts sections. At the end, score is calculated by dividing the obtained score by total (50) multiplied by 100.

  2. Pressure Pain Threshold (PPT) [ Time Frame: 2 weeks ]
    Changes from the Baseline Pressure Pain Threshold (PPT) will taken with the help of Algometer

Secondary Outcome Measures :
  1. Visual Analogue scale(VAS) [ Time Frame: 2 weeks ]
    Changes from base Line Visual Analogue scale is a scale for pain starting from 0-10. where 0 indicate no pain and 10 indicate severe pain

  2. Range Of Motion of cervical [ Time Frame: 2 weeks ]
    Changes from the Baseline range of Motion of cervical spine will take with the Help of Goniometer

  3. The Hospital Anxiety and Depression Scale (HADS) [ Time Frame: 2 weeks ]
    HADS is a valid and reliable self-rating scale that measures anxiety and depression in both hospital and community settings. The HADS is a fourteen-item scale. Seven of the items relate to anxiety and seven relate to depression.The "0-7" score indicates normal condition,"8-10" score indicates boarderline case and "11-21" score indicates the abnormal case.
