“…The microcirculatory blood flow is proportional to both the intensity and the Doppler shift of the light scattered back by the moving cells. The algorithm used to calculate the blood flow has been reported in our previous study [ 32 ]. Here, the microcirculatory flow measured through LDF is expressed using an arbitrary unit defined using a designated calibration process.…”

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.

“…15 Use of a FIR warming blanket for 20 min improved microcirculation, as measured by laser Doppler flow, in subjects with type 2 diabetes. 22 Together, these studies suggest that FIR therapy delivered through garments or textiles have promising potential to improve peripheral circulation in patients with diabetes, but overall there is a paucity of peer reviewed clinical studies in individuals with diabetes. Given that diabetic foot disease due to microcirculatory dysfunction is a major and costly complication of diabetes, use of FIR textiles and garments as a complementary approach to improving microcirculation is attractive.…”

Use of far infrared (FIR) energy may improve peripheral circulation. This study aimed to determine whether FIR delivered through textiles improves peripheral microcirculation as measured by transcutaneous oximetry (TcPO2) in individuals with diabetes mellitus (DM). Methods A single-center, prospective, randomized, placebo-controlled, double-blinded, crossover study of 32 subjects with either type 1 or type 2 DM. An active FIR wrap followed by a placebo wrap (or vice versa) was applied to the arm, calf, ankle, and forefoot for 60 min each with continuous TcPO2 measurements. The treatment effect of the active versus placebo wrap was estimated using a linear mixed effect model adjusted for period, sequence, baseline value, and anatomic site. Results The active FIR wrap increased mean TcPO2 at the arm (2.6 ± 0.8 mmHg, p = .002), calf (1.5 ± 0.7 mmHg, p = .03), and ankle (1.7 ± 0.8 mmHg, p = .04) and composite of all sites (1.4 ± 0.5 mmHg, p = .002) after 60 min. The estimated treatment effect was significant for the active FIR wrap at the calf (1.5 ± 0.7 mmHg, p = .045) and in composite of all sites (1.2 ± 0.5 mmHg, p = .013). Conclusion Short-term exposure to FIR textiles improves peripheral tissue oxygenation in patients with diabetes.

“…MMBF represents the mean blood flow of each subject during the 5 min measurement. The detailed working theory and algorithms of LDF were described previously [ 19 ], and other measurement conditions and requirements such as LDF recording duration and room temperature were based on our other previous studies [ 9 , 14 ].…”

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.
