“…This post-contraction phase has been thought to be a critical factor for assessing and recognizing if the BF is sufficient to meet metabolic demand (44). The present study showed that isotonic masseter muscle contractions were associated with increased intramuscular BF in the masseter muscle compared to that during rest.…”

“…Due to the small sample size, the study may have been under-powered but the study clearly shows that the magnitude of BF responses following noxious stimulation is modest. We also note that several previous studies on BF used relatively small sample sizes (5,6,43,53,54). Future studies need to improve this point, for example, with the use of non-invasive probes (55,56).…”

“…This might be the effect of a reactive hyperaemia, which has been thought to be associated with SEMA, indicating a compensation for an insufficient blood flow during SEMA (9).

“…Later, it has been suggested that chronic muscle pain could be related to localised disturbances of intramuscular blood flow leading to a lower level of oxygen distribution, hypoxia and microcirculatory changes that may involve subclinical inflammatory changes in the affected tissue facilitating pain (9)(10)(11). Using near-infrared spectroscopy, Delcanho et al showed less perfusion in the masseter muscle immediately after submaximal isometric contractions in patients with chronically painful masticatory muscles than in healthy participants (12).…”

Myofascial pain associated with temporomandibular disorders has often been linked to pathological muscle hyperactivity. As a result, localised disturbances of intramuscular blood flow could lead to a lower level of oxygen distribution, hypoxia and microcirculatory changes. To assess haemodynamic changes in the masseter muscle during sustained elevated muscle activity (SEMA). Sixteen healthy participants performed thirty 1-min bouts of SEMA with intervals of 1-min 'rest' periods between the bouts on a bite force transducer device. The participants completed three sessions with different percentage of their maximal voluntary occlusal bite force (MVOBF): 0% (no task), 10% or 40% MVOBF tasks. The order of the sessions was randomised with 1- to 2-week intervals. Haemodynamic characteristics of the masseter muscle were estimated with use of a laser blood oxygenation monitor. Tissue blood oxygen saturation (StO ) during SEMA was lower than during rest (P < 0·001). The relative changes in total haemoglobin (Total-Hb) and StO were influenced by condition (SEMA and rest) and with interactions between condition and session (0%, 10% and 40% MVOBF tasks). These results suggest that SEMA may lead to hypoxia in the masseter muscle and that the haemodynamic characteristics and muscle symptoms depend on the magnitude of muscle contractions. Overall, the present findings may help to provide better insights into relationships between jaw muscle activity, haemodynamic changes and symptom developments with implications for clinical conditions such as bruxism characterised by different levels of tooth-grinding and tooth-clenching muscle activity.

“…The radioactive inert gas xenon-133, which diffuses freely across cell membranes and is cleared from the tissue at a rate that is largely determined by the blood flow, has been used extensively to estimate IMBF (2)(3)(4)(5)(6)(7). In particular, this method has also been used in the masticatory muscles, indicating an insufficient IMBF during static and dynamic activities at a high rate (8)(9)(10)(11). Measurements of 133Xe clearance have been found to be poorly reproducible in other muscles when performed in the clinic (5,7,12).…”

Reproducibility of estimation of blood flow in the human masseter muscle from measurements of¹³³Xe clearance

The reproducibility of estimations of the masseter intramuscular blood flow (IMBF) was assessed bilaterally within and between clinical sessions. The 133Xe clearance in nine normal individuals was measured before, during, immediately after, and after endurance of isometric contraction at an attempted level of 50% of maximum voluntary clenching contraction. An overall low reproducibility of the estimations was found. This result was probably caused by uncertainties about the exact site of intramuscular 133Xe deposition, errors in assessment of the plots of clearance, and variabilities in the relative contraction levels sustained and, especially, in the overall muscle effort. In agreement with previous reports concerning other skeletal muscles, the 133Xe clearance method provided inconsistent estimates of absolute values of IMBF also in this clinical setting. Although there was a high intra-individual variation in the relative level of isometric contraction sustained, the endurance test induced distinct changes in IMBF, among which the estimate of post-endurance hyperemia was the most consistent for each individual. Therefore, measurements of 133Xe clearance seem to be useful to detect intra-individual changes in masseter IMBF resulting from isometric work.
