“…To deepen the spinal mechanisms mediating the agonist–antagonist relationship, evoking the H -reflex with a prior stimulation of the antagonist nerve may result in the D1 presynaptic inhibition, i.e., the presynaptic inhibition of H -reflex mediated by I a afferent of the antagonist muscle, reciprocal inhibition or I b -afferent (Baudry et al 2011 ). Similarly, the lack of change in the M wave revealed that no change in neuromuscular transmission occurred (Rozand et al 2015 ). Since the peripheral contribution to the force-generating capacity was demonstrated not to occur in the stretched muscle (Trajano et al 2017 ; Cè et al 2020 ), our findings for the antagonist muscle were actually expected.…”

“…Surface electromyography (sEMG) coupled with peripheral nerve stimulation could help to estimate the possible neuromuscular changes induced by passive stretching of the antagonist muscle (Rozand et al 2015 ). Particularly, the H -reflex overall reflects the response of the motoneuron pool to a volley from large-diameter primary muscle spindle afferents (Rozand et al 2015 ). Additionally, I a pathways and I b afferents exert an influence on the H -reflex (McNeil et al 2013 ).…”

Purpose The present study investigated whether or not passive stretching increases the force-generating capacity of the antagonist muscle, and the possible neuromuscular mechanisms behind. Methods To this purpose, the neuromuscular function accompanying the force-generating capacity was assessed in 26 healthy male volunteers after passive stretching and in a control session. Before and after passive intermittent static stretching of the plantar flexors consisting of five sets × 45 s + 15 s-rest, maximum voluntary isometric contraction (MVC) and surface electromyographic root mean square (sEMG RMS) were measured in the tibialis anterior (the antagonist muscle). Additionally, evoked V wave, H-reflex, and M wave were elicited by nerve stimulation at rest and during MVC. Ankle range of motion (ROM) and plantar flexors MVC and EMG RMS were measured to check for the effectiveness of the stretching manoeuvre. Results No change in MVC [p = 0.670; effect size (ES) − 0.03] and sEMG RMS/M wave during MVC (p = 0.231; ES − 0.09) was observed in the antagonist muscle after passive stretching. Similarly, no change in V wave (p = 0.531; ES 0.16), H-reflex at rest and during MVC (p = 0.656 and 0.597; ES 0.11 and 0.23, respectively) and M wave at rest and during MVC (p = 0.355 and 0.554; ES 0.04 and 0.01, respectively) was observed. An increase in ankle ROM (p < 0.001; ES 0.55) and a decrease in plantar flexors MVC (p < 0.001; ES − 1.05) and EMG RMS (p < 0.05; ES − 1.72 to − 0.13 in all muscles) indicated the effectiveness of stretching protocol. Conclusion No change in the force-generating capacity and neuromuscular function of the antagonist muscle after passive stretching was observed.

“…Electrical nerve stimulation is also used to assess the voluntary activation level (VAL) by using the twitch interpolation technique and the twitch contractile properties. The twitch interpolation technique consists of applying a supramaximal electrical nerve stimulation during a maximal voluntary contraction (superimposed stimulation) [ 7 ]. If the superimposed stimulation induces a torque increase, it means that the participant is not able to fully activate its muscles [ 8 – 10 ].…”

IntroductionThis study aimed to determine the intra- and inter-session reliability of neuromuscular assessment of plantar flexor (PF) muscles at three knee angles.MethodsTwelve young adults were tested for three knee angles (90°, 30° and 0°) and at three time points separated by 1 hour (intra-session) and 7 days (inter-session). Electrical (H reflex, M wave) and mechanical (evoked and maximal voluntary torque, activation level) parameters were measured on the PF muscles. Intraclass correlation coefficients (ICC) and coefficients of variation were calculated to determine intra- and inter-session reliability.ResultsThe mechanical measurements presented excellent (ICC>0.75) intra- and inter-session reliabilities regardless of the knee angle considered. The reliability of electrical measurements was better for the 90° knee angle compared to the 0° and 30° angles.ConclusionsChanges in the knee angle may influence the reliability of neuromuscular assessments, which indicates the importance of considering the knee angle to collect consistent outcomes on the PF muscles.

“…However, most of these techniques have to be synchronized with EMG to detect muscle fatigue and they cannot assess central fatigue. On the other hand, central fatigue can be evaluated either with percutaneous nerve stimulation -with an electrical nerve stimulation-or transcranial magnetic stimulation -with a nerve cells magnetic stimulation- (Gandevia, 2001;Taylor and Gandevia, 2001;Rozand et al, 2015) during maximal contractions. If the stimulation evokes an extraforce, it suggests that central fatigue is present (Merton, 1954).…”

Background: Clinical tests for detecting central and peripheral shoulder fatigue are limited. The discrimination of these two types of fatigue is necessary to better adapt recovery intervention. The Kinematic Theory of Rapid Human Movements describes the neuromotor impulse response using lognormal functions and has many applications in pathology detection. The ideal motor control is modeled and a change in the neuromuscular system is reflected in parameters extracted according to this theory. Objective: The objective of this study was to assess whether a shoulder neuromuscular fatigue could be detected through parameters describing the theory, if there is the possibility to discriminate central from peripheral fatigue, and which handwriting test gives the most relevant information on fatigue. Methods: Twenty healthy participants performed two sessions of fast stroke handwriting on a tablet, before and after a shoulder fatigue. The fatigue was in internal rotation for one session and in external rotation during the other session. The drawings consisted of simple strokes, triangles, horizontal, and vertical oscillations. Parameters of these strokes were extracted according to the Sigma-Lognormal model of the Kinematic Theory. The evolution of each participant was analyzed through a U-Mann-Whitney test for individual comparisons. A Hotelling's T 2-test and a U-Mann-Whitney test were also performed on all participants to assess the group evolution after fatigue. Moreover, a correlation among parameters was calculated through Spearman coefficients to assess intrinsic parameters properties of each handwriting test. Results: Central and peripheral parameters were statistically different before and after fatigue with a possibility to discriminate them. Participants had various responses to fatigue. However, when considering the group, parameters related to the motor program execution showed significant increase in the handwriting tests after shoulder fatigue. The test of simple strokes permits to know more specifically where the fatigue comes from, whereas the oscillations tests were the most sensitive to fatigue.
