“…Probing depth of NIRS can be centimeters sufficient for measurements of muscles in human subjects [17]. NIRS has been successfully utilized in a few therapeutic evaluation studies, such as massage therapy [18,19], electrical stimulation [20,21] and deep venous thrombosis [22].…”

Cupping therapy has been used in traditional Chinese medicine for thousands of years to relieve muscle pain/tendency/fatigue and to cure or reduce symbols of other diseases. However, its therapeutic effect is sparsely interpreted in the language of modern physiology. To objectively evaluate its therapeutic effect, we focused on dry cupping treatment and utilized near-infrared spectroscopy (NIRS) to assess the concentration change in oxyhemoglobin ([HbO 2 ]), deoxy-hemoglobin ([Hb]), and blood volume in the course of cupping therapy over 13 volunteers on the infraspinatus muscle, where is usually applied for shoulder pains. Both a prominent drop in [Hb] and a significant elevation in [HbO 2 ] in the tissue surrounding the cupping site were observed during both cupping and post-treatment, manifesting the enhancement of oxygen uptake. This resulting promotion indicates potential positive therapeutic effect of cupping therapy in hemodynamics for facilitating muscular functions.

“…[30][31][32] DCS uses a coherent NIR light source to penetrate tissue and monitors temporal light intensity fluctuations caused by moving scatterers (primarily red blood cells) to calculate a flow index (αD B ). DCS techniques for rBF measurements have been used previously to study tissue hemodynamics in skeletal muscle 13,[33][34][35][36] and validated in a variety of tissues/organs against other local BF measurements such as xenon-CT, 37 13 Although previous studies have employed this type of hybrid instrument in studying skeletal muscle, measurement is limited to providing only relative values of BF and _ VO 2 . In addition, DCS is highly sensitive to muscle fiber motion, which can distort the signal and cause significant overestimation of flow.…”

Abstract. This study investigates a method using novel hybrid diffuse optical spectroscopies [near-infrared spectroscopy (NIRS) and diffuse correlation spectroscopy (DCS)] to obtain continuous, noninvasive measurement of absolute blood flow (BF), blood oxygenation, and oxygen consumption rate ( _ VO 2 ) in exercising skeletal muscle. Healthy subjects (n ¼ 9) performed a handgrip exercise to increase BF and _ VO 2 in forearm flexor muscles, while a hybrid optical probe on the skin surface directly monitored oxy-, deoxy-, and total hemoglobin concentrations ([HbO 2 ], [Hb], and THC), tissue oxygen saturation (S t O 2 ), relative BF (rBF), and relative oxygen consumption rate (r _ VO 2 ). The rBF and r _ VO 2 signals were calibrated with absolute baseline BF and _ VO 2 obtained through venous and arterial occlusions, respectively. Known problems with muscle-fiber motion artifacts in optical measurements during exercise were mitigated using a novel gating algorithm that determined muscle contraction status based on control signals from a dynamometer. Results were consistent with previous findings in the literature. This study supports the application of NIRS/DCS technology to quantitatively evaluate hemodynamic and metabolic parameters in exercising skeletal muscle and holds promise for improving diagnosis and treatment evaluation for patients suffering from diseases affecting skeletal muscle and advancing fundamental understanding of muscle and exercise physiology.

Background: The goal of this study was to investigate acute effects of a special kind of manual therapy developed by Mohamed Khalifa (RegentK) compared to standard physiotherapy on regional oxygen saturation (rSO₂) of knee tissues in patients with completely ruptured anterior cruciate ligament (ACL). Methods: Twenty patients were enrolled in this study and randomly assigned to receive either RegentK (group A; n = 10, 8 female, 2 male, mean age ± SD 31.3 ± 8.5 years) or physiotherapy (group B; n = 10, 6 female, 4 male, mean age 34.8 ± 10.2 years). The values of rSO₂, assessed using near-infrared spectroscopy, were registered anterolaterally and anteromedially on both the injured and the healthy (control) knee. Results: rSO₂ increased significantly (p < 0.001) after RegentK on both registration sites of the injured knee, whereas after physiotherapy only the anterolateral side showed significant increases. Interestingly, we found significant increases in rSO₂ also on the control knee after RegentK; in group B, these results were insignificant. Conclusion: We conclude that manual therapy influences the hemodynamics of muscles and deeper structures. The results will also serve to quantify the effects of nonpharmacological and nonsurgical interventions (e.g. RegentK) on the microvascular circulation in deep tissue after a complete rupture of the ACL.
