Novel approach in traditional Chinese medicine: Myofascial pain syndrome is characterized as myofascial trigger points (MTrP) in taut bands. Previous literature showed that MTrPsarehypoechoeic areasidentified by sonoelastography and active MTrPshad larger area than normal and latent MTrPs.However, no studies to date use MTrPs' cross-sectional areas as an objective outcome measure to assess treatment effect and there is no studies discussing the effects of Gua-Shaon trigger points. This study aimed toquantify the treatment effects of Gua-Shaon female upper trapezius active MTrPswithsonoelastographicmeasurement. Three office female workers (37.3 ± 3.0 y/o)with active trigger points on their upper trapezius,who had neck pain for the past 3 months were recruited. Gua-sha intervention was applied to the more painful side for under 5 minutes. Outcome measures include:MTrPs’ cross-sectional area measurements through sonoelastography,neck disability index (NDI) and visual analogue scale (VAS)atimmediately after treatment, two days and one week follow up were evaluated. Results showed a reduction incross-sectional area from baseline (24.38 ± 5.08 mm2) to immediately (15.67 ± 1.80 mm2), two days (17.03 ± 5.26 mm2) and one week after treatment (22.92 ± 4.75 mm2). Positive treatment effects were alsoobserved forboth NDI (54%) and VAS (100%). Preliminary findings showed that sonoelastographicmeasurement is feasiblein quantifying treatment effects and Gua-Sha is an effective treatment on female upper trapezius active MTrPs with objective and subjective measures.
