Sentence examples for motor unit stimulation from inspiring English sources

Therefore, emphasis was put on the elucidation of the response of different isoforms in phenotypically distinct muscles and the influence of slow/fast motor unit stimulation frequencies.

CaMKII autophosphorylation at Thr287 was assessed in three muscle compartments of the rat after slow or fast motor unit-type stimulation and was compared against a computational model (CaMuZclE) coupling myocellular calcium dynamics with CaMKII Thr287 phosphorylation.

It is unclear which CaMKII isoforms mediate these effects in skeletal muscle but their autophosphorylation pattern in response to fast or slow motor unit-type stimulation might provide clues about CaMKII isoform-specific functions.

However, several researchers have argued that motor unit recruitment during percutaneous electrical stimulation is nonselective, i.e. motor units are driven in a random manner, without obvious sequencing related to contractile properties [17] [19].

For example, projections of group Ia pretibial flexors afferents to quadriceps (Quads) have been assessed by using the heteronymous facilitation of Quads reflex and voluntary firing of motor units after the stimulation of the common peroneal nerve [18], [19].

The recruitment order of motor units during electrical stimulation is considered quite different from the natural pattern, which is traditionally interpreted as reversed recruitment order (i.e. from fast to slow type) due mainly to the low input-impedance of fast motor units with thick axons [14] [16].

If there is this much controversy and debate concerning the validity of this technique concerning neural adaptations after VST, these difficulties are further compounded under the conditions of EST due to the differences in motor unit activation between voluntary versus stimulation-evoked contractions.

We used this model to predict possible CaMKII isoform differences in level alterations of Thr287 phosphorylation between stimulation protocols and motor unit types.

The total motor unit response was determined by supramaximal stimulation of the peroneal nerve axons to produce a maximal M-wave.

Other features of CIM include increased CMAP duration, normal SNAPs, reduced muscle excitability on direct stimulation and myopathic motor unit potentials on needle electromyography.

Effect of an electric stimulation facilitation program on quadriceps motor unit recruitment after stroke.
