SIHI and LIHI during rest and contraction contralateral to CS and TS. Histograms displaying group averaged data (with standard errors) of SIHI (top) and LIHI (bottom). Data combines IHI directions and active tasks (isometric contraction and pen holding). 'CS active' refers to IHI recorded when the FDI muscle contralateral to the CS was contracted. 'Test active' is IHI recorded when the FDI muscle contralateral to the TS was contracted. Both SIH and LIHI demonstrate reduced IHI during active tasks compared to rest. Contraction contralateral to either the CS or the TS reduces IHI similarly. * denotes significant post-hoc tests (p < 0.05) of main effect of Task.
