“…Prior to each testing session, the NIRO‐200 initialization procedure was carried out to set each laser power automatically in order to establish the optimum measurement conditions, and all used procedures were previously described by [21,22]. NIRS signals were sampled at 2 Hz by the NIRO‐200 apparatus and collected simultaneously with torque data using the Biopac Acqknowledge Data Acquisition software.…”

Aims Facioscapulohumeral muscular dystrophy (FSHD) causes progressive muscle weakness and loss. This study aims to compare changes in quadriceps oxygenation and hemodynamics during maximal voluntary quadriceps isometric contraction (MVCQ) and to determine the relationships between these parameters and systemic oxidative stress markers and muscle structural parameters and muscle volume in patients with FSHD and healthy controls. Methods and results 17 patients with FSHD and 14 sedentary healthy controls were matched for age and physical activity level. Blood antioxidant status and stress markers were evaluated. The quadriceps tissue oxygenation index was evaluated by near infrared spectroscopy during MVCQ. Quadriceps volume was determined by magnetic resonance imaging. Quadriceps muscle samples were obtained to evaluate muscle fiber typology and mitochondria morphology by transmission electron microcopy (TEM). Groups were compared by the unpaired Student t‐test or by the non‐parametric Kruskal ‐ Wallis test in case of skewed distributions with p<0.05. Associations were assessed by Spearman correlations. Compared to controls, patients with FSHD displayed a significantly lower local O2 consumption per second that was correlated with significantly lower MVCQ and systemic oxidative stress marker levels. Although no difference in muscle typology was observed between groups, TEM showed abnormal aggregation of mitochondria near blood capillaries in FSHD muscles. Conclusions These results suggest that patients with FSHD have a lower O2 demand during MVCQ and that TOI measured by NIRS during MVC could be useful to determine the muscle oxidative capacity. Furthermore, these adaptations are related to the muscle structure reorganization linked to the occurrence of oxidative stress.

“…They examined the biceps brachii muscle and they used a NIRS device identical to the one used in the present study to evaluate oxygenation. They concluded that local O 2 demand during a NMES-induced isometric contraction of 30 seconds was similar in using a 30 Hz and a 75 Hz current [47,48]. …”

BackgroundIntensive care unit-acquired weakness (ICUAW) is a common complication, associated with significant morbidity. Neuromuscular electrical stimulation (NMES) has shown promise for prevention. NMES acutely affects skeletal muscle microcirculation; such effects could mediate the favorable outcomes. However, optimal current characteristics have not been defined. This study aimed to compare the effects on muscle microcirculation of a single NMES session using medium and high frequency currents.MethodsICU patients with systemic inflammatory response syndrome (SIRS) or sepsis of three to five days duration and patients with ICUAW were studied. A single 30-minute NMES session was applied to the lower limbs bilaterally using current of increasing intensity. Patients were randomly assigned to either the HF (75 Hz, pulse 400 μs, cycle 5 seconds on - 21 seconds off) or the MF (45 Hz, pulse 400 μs, cycle 5 seconds on - 12 seconds off) protocol. Peripheral microcirculation was monitored at the thenar eminence using near-infrared spectroscopy (NIRS) to obtain tissue O2 saturation (StO2); a vascular occlusion test was applied before and after the session. Local microcirculation of the vastus lateralis was also monitored using NIRS.ResultsThirty-one patients were randomized. In the HF protocol (17 patients), peripheral microcirculatory parameters were: thenar O2 consumption rate (%/minute) from 8.6 ± 2.2 to 9.9 ± 5.1 (P = 0.08), endothelial reactivity (%/second) from 2.7 ± 1.4 to 3.2 ± 1.9 (P = 0.04), vascular reserve (seconds) from 160 ± 55 to 145 ± 49 (P = 0.03). In the MF protocol: thenar O2 consumption rate (%/minute) from 8.8 ± 3.8 to 9.9 ± 3.6 (P = 0.07), endothelial reactivity (%/second) from 2.5 ± 1.4 to 3.1 ± 1.7 (P = 0.03), vascular reserve (seconds) from 163 ± 37 to 144 ± 33 (P = 0.001). Both protocols showed a similar effect. In the vastus lateralis, average muscle O2 consumption rate was 61 ± 9%/minute during the HF protocol versus 69 ± 23%/minute during the MF protocol (P = 0.5). The minimum amplitude in StO2 was 5 ± 4 units with the HF protocol versus 7 ± 4 units with the MF protocol (P = 0.3). Post-exercise, StO2 increased by 6 ± 7 units with the HF protocol versus 5 ± 4 units with the MF protocol (P = 0.6). These changes correlated well with contraction strength.ConclusionsA single NMES session affected local and systemic skeletal muscle microcirculation. Medium and high frequency currents were equally effective.

“…They also used near infrared spectroscopy, which is a technique particularly suitable for investigating local metabolic changes of stimulated muscles (Muthalib et al 2009), and were able to demonstrate that, besides contractile activity, muscle oxygen consumption and hyperaemia were significantly increased when motor point location was carefully determined with a pen electrode rather than being inferred from several legally marketed motor point charts. We recommend that the procedure described by Gobbo et al (2011), which is completed in less than a minute, should be consistently incorporated in both clinical and research contexts to optimize NMES application.…”
