Timing as a prominent factor of the Jendrassik manoeuvre on the H reflex
Open accessAbstract
The influence of the Jendrassik manoeuvre on the myotatic reflex was analysed using a strain gauge as an indicator of the upper extremity movement and the H reflex of the soleus muscle as the test reflex. The most prominent factor responsible for the enhancement was not the speed or the strength of the manoeuvre but the timing from the instruction.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
