Multi-digit maximum voluntary torque production on a circular object.
Individual digit-tip forces and moments during torque production on a mechanically fixed circular object were studied. During the experiments, subjects positioned each digit on a 6-dimensional force/moment sensor attached to a circular handle and produced a maximum voluntary torque on the handle. The torque direction and the orientation of the torque axis were varied. From this study, it is con...
متن کاملQuarantine: voluntary or not?
By utilizing quarantine and isolation as public health tools we are in many ways battling twenty-first century pathogens with a fourteenth century toolbox. It is important for all to recognize the technical difference between the distinct public health measures of isolation and quarantine. Isolation is the separation and/or restricted movement of persons with a contagious disease from the large...
متن کاملCentral excitability does not limit postfatigue voluntary activation of quadriceps femoris.
After fatigue, motor evoked potentials (MEP) elicited by transcranial magnetic stimulation and cervicomedullary evoked potentials elicited by stimulation of the corticospinal tract are depressed. These reductions in corticomotor excitability and corticospinal transmission are accompanied by voluntary activation failure, but this may not reflect a causal relationship. Our purpose was to determin...
متن کاملAging does not affect voluntary activation of the ankle dorsiflexors during isometric, concentric, and eccentric contractions.
This study examines the age-related deficit in force of the ankle dorsiflexors during isometric (Iso), concentric (Con), and eccentric (Ecc) contractions. More specifically, the contribution of neural and muscular mechanisms to the loss of voluntary force was investigated in men and women. The torque produced by the dorsiflexors and the surface electromyogram (EMG) from the tibialis anterior an...
متن کاملPoint: the interpolated twitch does/does not provide a valid measure of the voluntary activation of muscle.
TO THE EDITOR: There appears to be a general consensus among the participants in the debate (see Comments in Ref. 4) that the additional electrically elicited force on top of a voluntary isometric contraction is a qualitative measure of muscle (in)activation, whereas there is less agreement whether single pulses, doublets, or pulse trains should be used. We made sure not to complicate the debat...
