简要总结
This study aimed to verify the mechanical and clinical effects of instrumented massage on myofascial trigger points of trapezius muscle in adult subjects.
详细描述
Background: There are several therapies currently used to treat myofascial trigger points, including conservative and invasive techniques. It has been shown that conservative techniques including therapeutic massage, stretching, transcutaneal electrical nerve stimulation, spray and stretch, cold laser treatment, and ultrasound are the most applied treatments for myofascial pain syndrome, but no single strategy has proved to be universally successful. Instrumented massage has shown clinical effectiveness on shoulder pain, low back pain, and only one study (case report) on myofascial trigger points. This study aimed to verify the mechanical and clinical effects of instrumented massage on myofascial trigger points of trapezius muscle in adult subjects.
Methods/Design: The study includes 31 volunteers with myofascial trigger points on right trapezius muscle. Clinical and patient data were obtained from questionnaires, VAS, algometry, sono-myoelastography and myotonometry. Also, physiotherapist grip strength was measured. Subjects were randomly allocated into one of two groups: Instrumented massage or Manual massage. The intervention consisted in a single 20 minutes session of massage on the back and neck by the same therapist, depending of the group, massage was applied manually or instrumented.

结局指标
主要结局
• Stiffness of the right upper trapezius myofascial trigger point measured by MyoptronPRO.
时间窗: 10 minutes
Stiffness characteristics will be measured using a handheld MyotonPRO device (MyotonPRO, Myoton Ltd, Estonia). MyotonPRO has shown high levels of reliability in a session or between sessions both by the same operator (intra-rater) and between different operators (inter-rater), both in young subjects and elderly (Aird et al., 2012) (Mullix et al., 2012). Stiffness (N/m) will be calculated by software of MyotonPRO (Vain, 1994, 1995). Stiffness is the ability of tissue to restore it shape after removing of external force acting on the muscle.
• Pain as measured by VAS
时间窗: 10 minutes
The Visual Analogue Scale (VAS) was designed to allow a subjective assessment of pain. A VAS is usually a horizontal line of 10 cm. with perpendicular lines at the ends, which are defined as the extreme limits of the painful experience. Previous studies have shown that the VAS has adequate psychometric properties, including test-retest reliability (r = 0.78) and convergent validity with other measures of pain such as the McGill Pain Questionnaire (r = 0.49 to 0.65) (Sriwatanakul K ., 1983).
• Stiffness (Hz) of the right upper trapezius myofascial trigger point measured by sono-myoelastography.
时间窗: 10 minutes
Sono-myoelastography uses an external vibration source with a frequency less than 1000 Hz in conjunction with Doppler techniques to identify localized regions of increased tissue stiffness (Muro-Culebras, 2013). In this study vibrations will be produced in the right upper trapezius muscle using an external massage vibrator (Model NC70209, North Coast Medical, Gilroy, CA, USA) modified with a flat and elongated applicator (with an application area of 1 x 4 cm). This vibration source will be placed approximately 2-3 cm away from each of the points marked as ''positive'' in the clinical examination and induce vibrations of about 92 Hz. By use of the power Doppler technique, the sono-myoelastography images will be collected while applying vibrations.
