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.

Detailed description: Myofascial Trigger Point (MTrP) is a hyperirritable spot in the taut bands of the skeletal muscles' fascia which is palpable and tender, on direct compression can produce referred pain in its reference zone, local tenderness and elicit a local twitch response. MTrP can be identified as either active or latent. According to Simons et al. that active and latent trigger points are associated with tenderness, muscle dysfunction, muscle weakness and restricted muscle length. An active MTrP causes spontaneous pain complaint in surrounding tissue and generally in its pain reference zone while latent MTrP physically exist but doesn't associate with spontaneous pain complaint. However, by direct compression latent MTrP can cause local pain on the site of taut band. Myofascial trigger points (MTrP) are considered one of the most common cause of musculoskeletal pain. Active MTrP are considered to be more prevalent in upper fibers of trapezius muscle (45% in right upper trapezius and 25% in left upper trapezius and cause neck pain and shoulder discomfort. Predisposing Factors associated to MTrP can be either mechanical stress (such as overuse of muscles, repetitive strain injury, work related mechanical disorder, awkward posture and degenerative condition) or metabolic stress( such as hypo metabolic state and vitamin deficiency).According to integrated hypothesis presented by Simon, MTrP is believed to develop after a local injury either repetitive micro trauma or gross trauma to the muscle fibers. The diagnostic criteria of MTrP used by recent studies which is presented by Simons et al. is based on palpation of muscle. A well-trained clinician palpates the muscle to localize the active MTrP. During physical examination, a hyper sensitive spot within taut bands of muscle fibers, Palpation of recognized spot results in referred pain within reference zone, palpation of recognized spot elicits a jump sign (defensive movement), palpation may result in local twitch response defined as visible contraction of muscle. There are varieties of physiotherapy interventions for the management of MTrP which maybe invasive and non-invasive such as dry needling, anesthetic injections, spray and stretch, ischemic compression and muscle energy techniques. A very limited evidence found on effects of spray and stretch technique versus sustain pressure for the Management of upper trapezius trigger points with flaws in methodology design. To fill the gap, this study is formulated to determine the effects of spray and stretch technique vs sustain pressure for the management of upper trapezius MTrP. Study will find out most effective treatment for management of upper trapezius and would contribute to educate and treat the patient with most simple and effective treatment approach.

Literature review A systematic and evidence-based search of relevant literature were performed by utilizing PubMed and Google Scholar as search engines.

A study conducted in 2017 regarding spray and stretch technique versus progressive pressure release on treatment of myofascial pain trigger point reported that spray and stretch technique was more effective in increasing functional activities while progressive pressure release was more effective in decreasing pain

Another study in 2017 regarding Immediate effect of spray and stretch on trapezitis demonstrated that spray and stretch technique is effective in terms to increases range of motion and increase pain pressure threshold on acute trapezitis.

A study in 2017 found that the number of active MTrP was positively associated with the physical burden of headache and trait anxiety.

Study in 2013 concluded that Vapocoolant spray may be more effective than ice as an analgesic for IV insertion. Subjects were more satisfied with vapocoolant spray.

Another study in 2014 investigated that spray and stretch had a short-term (\<6h) effect in reducing post needling soreness of a latent MTrP and Pressure pain threshold did not significantly change after spray and stretch.

Study in 2018 reported that ischemic compression and progressive sustained pressure both have significant effect on improving the pain of patients with chronic musculoskeletal pain pathologies.
