The aim of the present study was to investigate the possible effect of cryotherapy combined with passive stretching and moist heat combined with passive stretching, respectively, on active myofascial trigger points of the shoulder girdle. The study was a randomized comparative clinical trial consisting of 30 patients diagnosed with active myofascial trigger points in the shoulder girdle muscles. The selected patients received either cryotherapy combined with passive stretching (n = 15) or moist heat combined with passive stretching (n = 15). Subjective data was collected using the Neck Disability Index, the Numerical Pain Rating Scale and the Short-Form McGill Pain Questionnaire. The objective data was obtained by taking algometer readings from the active trigger points and by measuring cervical spine range of motion using analogue goniometer. The data were analysed using the appropriate nonparametric statistical tests, along with post hoc power and effect size analysis. Both treatments had a significant effect, indicating improvement. However, there was no difference between the two groups, suggesting that both interventions had equivalent effects. Effect size outcomes supported the statistical results. This study suggests that both cryotherapy combined with passive stretching and moist heat combined with passive stretching produce an improvement in subjects suffering from active myofascial trigger points of the shoulder girdle. Furthermore, both treatments provided equal benefit. It is suggested that clinical use of these modalities should be based on patient preference and/or tolerance.
