“…Our results suggested that the state of the lower resting blood flow could be related to microcirculatory insufficiency. By contrast, the symptom of the high blood flow was also found in Chia's [27] study, where the microcirculatory perfusion was also monitored through high-power LDF. Chia found that the high-blood-flux phenomenon in the neck and shoulder regions was only found in adults with a sedentary lifestyle, whose neck and shoulder pain levels were rated as 2.8 ± 2.4 on a 10-point visual analog scale of 0 (no pain) to 10 (unbearable pain).…”

“…Since both the symptoms of microcirculatory insufficiency [ 26 ] and the high-blood-flow [ 27 ] were found in patients with neck and shoulder pain in previous studies, our first hypothesis states that the standard deviation of the skin microcirculation around the neck and shoulders of patients with limited cervical spine movement, which was determined through videofluoroscopy, should be larger. In addition, a sustained hyperemia was observed in the shoulder muscles of patients with neck and shoulder pain after the intervention of the office works [ 22 ], our second hypothesis states that the effect of massage intervention should be more vigorous in patients with postural neck and shoulder pain.…”

Vascular impairment is a crucial factor associated with chronic muscle pain, but relevant research from the microcirculatory aspect is lacking. Here, we investigated the differences in neck muscle microcirculation detected through laser-doppler flowmetry (LDF) and cervical biomechanics by a videofluoroscopic image in asymptomatic participants and patients with postural neck and shoulder pain. To understand the mechanism behind the effect of myofascial treatment, transverse friction massage (TFM) was applied and the immediate effects of muscular intervention on microcirculation were monitored. In total, 16 asymptomatic participants and 22 patients (mean age = 26.3 ± 2.4 and 25.4 ± 3.2 years, respectively) were recruited. Their neck muscle microcirculation and spinal image sequence were assessed. The differences in the baseline blood flow between the asymptomatic and patient groups were nonsignificant. However, the standard deviations in the measurements of the upper trapezius muscle in the patients were significantly larger (p < 0.05). Regarding the TFM-induced responses of skin microcirculation, the blood flow ratio was significantly higher in the patients than in the asymptomatic participants (p < 0.05). In conclusion, postintervention hyperemia determined through noninvasive LDF may be an indicator for the understanding of the mechanism underlying massage therapies and the design of interventions for postural pain.

“…The skin blood perfusion of the patient group was measured before treatment during their first visit to the rehabilitation department. Since myofascial pain can be diagnosed by the presence of one or more myofascial trigger points (MTrPs), it was defined as a hyperirritable spot in a palpable taut band of skeletal muscle fibers [ 8 , 17 , 18 ]. A high-power LDF device (VMS-LDF1-HP, Moor Instruments, Axminster, Devon, UK) operating at 785 nm and a laser power of less than 20 mW (complying with Class 3R of the IEC 60825-1:2007), and with a wide-separation (4 mm) noninvasive skin probe (VP1-V2-HP), was used to measure the microcirculatory blood perfusion at MTrPs on the affected shoulder for the patient group.…”

“…Furthermore, the continuous development of workplace health-promotion measurement tools is the focus of the next phase of efforts aimed to addressing the severity of musculoskeletal disorders. Methods to assess shoulder and neck pain include the visual analogue scale (VAS) score [ 5 ], Neck Disability Index, neck mobility, muscle strength [ 6 , 7 ], white-light spectroscopy, Laser Doppler Flowmetry (LDF) [ 8 , 9 ], and quantitative imaging biomarkers [ 10 ]. Salgado [ 11 ] discussed several techniques for evaluating microvasculature perfusion, such as LDF, intravital microscopy, and orthogonal polarization spectral imaging techniques.…”

Severe neck-shoulder pain induces functional limitations in both life and work. The purpose of this study was to determine the characteristics of shoulder microcirculation abnormality in workers. This study recruited 32 workers and patients, both n = 16. Questionnaires were administered, and Laser Doppler Flowmetry (LDF) was used to measure microcirculatory blood flow (MBF) at the myofascial trigger points (MTrPs) on the shoulders. The absolute-deviationMMBF represented the mean MBF (MMBF) variability among subjects. The differences in the life characteristics, shoulder pain level, and microcirculatory characteristics at MTrPs between the two groups were compared. It was found that shoulder pain level was significantly higher in the patient than in the control group (p < 0.001). Deviation of the MMBF value beyond the postulated “normal range” of 60–80 was significantly higher in the patient than in the control group (p < 0.001). The MMBF deviation was significantly correlated with shoulder pain level, pain duration, and the symptom effect (p < 0.01, n = 32). A normal range for the MMBF of 60–80 on the shoulder near MTrPs is hypothesized for the first time based on this study. Noninvasive LDF can be used to assess abnormality in the MBF on shoulder MTrPs at an early stage.
