Tactile feedback plays a critical role in maximum finger force production

The Effect of Frequency of Transcutaneous Electrical Nerve Stimulation (TENS) on Maximum Multi-finger Force Production

“…These results are consistent with our recent study where MVF values decreased with the removal of cutaneous feedback (Shim et al, 2012).…”

“…Cutaneous feedback is known to be one of the major sensory modalities affecting the MVF production by the fingers of the hand (Collins, Knight, & Prochazka, 1999;Shim et al, 2012). Although the exact neurophysiological mechanism of changes in cutaneous sensation with TENS…”

Equivalent Bilateral Early Latency Cutaneous Reflex Amplitudes during Graded Contractions in Right Handers

“…Spinally mediated contributions have been assessed using the Hoffmann (H-) reflex but have provided mixed results and the data does not clearly distinguish between spinal and supraspinal influences [8,9]. Tactile feedback plays a critical role in maximal force production [10] and agonist-antagonist co-activation [11] which could potentially contribute to the functional asymmetries present in the majority of right handers. Therefore, the purpose of this paper was to explore possible spinally mediated contributions from the cutaneous receptors in the skin to the asymmetry in strength seen in right handers.…”

Difference of motor overflow depending on the impaired or unimpaired hand in stroke patients

“…Before the calculation, one frame was selected which represented the peak forces produced by the finger that was intended to move or the sum of all four fingers during the single finger or multiple finger tasks, respectively. In the current study, the contralateral independence (CI) was used as an index of the independence of the inter-hemispheres during a force production task, which was modified from the concept of force independence in a previous study (Shim et al, 2012). The CI was defined as the bilateral independence between hands in finger force production:…”
