Effects of Spray and Stretch On Postneedling Soreness And Sensitivity After Dry Needling Of A Latent Myofascial Trigger Point

This study had the objectives of investigating the effect of spray and stretch (SS) versus control on reducing post-needling soreness of one latent myofascial trigger point (MTrP) and if elevated levels of psychological distress are associated with increased post-needling pain intensity. A 72-hour follow-up, single-blind randomized controlled trial consisting of healthy volunteers (N=70:40 men,30 women) aged 18 to 36 years (mean±SD, 21±4y) with latent MTrP in one upper trapezius muscle was conducted. All subjects were given a dry needling application over the upper trapezius muscle. Then, participants were seperated at random into two groups: an intervention group, which received SS over the needled trapezius muscle, and a control group that did not receive any intervention. The primary outcome measures were the visual analog scale (VAS; at post-needling, post-treatment, 6, 12, 24, 48 and 72 hours), pressure pain threshold (PPT; at pre-needling, post-needling, 24 and 48 hours). Psychological distress was evaluated by the Symptom Checklist-90-Revised. Repeated measures analysis of variance (ANOVA) showed a significant interaction between group and time (F3,204.8=3.19, P.05). Repeated measures of covariance (ANCOVA) showed that none of the psychological covariates affected these results. Somatization, anxiety, interpersonal sensitivity and hostility were significantly correlated (P<.05) with post-needling pain intensity. Repeated measures ANOVA did not show a significant effect of SS on mechanical hiperalgesia (F2.6,175=1.9, P=.131, ηp2=0.02).

The study found the SS to have a short-term (less than 6 hours) effect reducing post-needling soreness of a latent MTrP. PPT did not significantly change after SS. Psychological factors are associated with post-needling pain.

Neck Pain

Out of all 291 conditions studied in the Global Burden of Disease 2010 Study, neck pain ranked 4th highest in terms of disability and 21st in terms of overall burden.
