Local muscle pressure stimulates the principal receptors for proprioception

In the ‘isometric’ condition, the semi-pronated hand was immobile whereas in the ‘sinusoidal’ condition the experimenter moved the participant’s hand continuously in the flexion-extension dimension so that the cursor reached the visual targets at a 0.5 Hz pace. The uploaded Excel file contains data used for statistical analyses and reflected in the Figures in "Local muscle pressure stimulates the principal receptors for proprioception" Sheet1: Fig2d_Isometric_NormFRQ.

Mean change in afferent firing rate (from baseline) in the five epochs of the isometric condition. Sheet2: Fig2fg_Isometric_PopReg_100ms. . Normalized ensemble population signals during in the isometric task.

Data are down-sampled using a moving average window of 100 ms. Sheet3: Sinusoidal_Angle_Rebased. Mean change in Angle in the five epochs of the sinusoidal condition.

Sheet4: Sinusoidal_NormEMG_Rebased. Mean change in EMG of the parent muscle in the five epochs of the sinusoidal condition. Sheet5: Fig3b_Sinusoidal_NormFRQ_Rebase.

Mean change in afferent firing rate (from baseline) in the five epochs of the sinusoidal condition. Sheet6: Sinusoidal_Velocity_Rebased. Mean change in Velocity in the five epochs of the sinusoidal condition.

Sheet7: Fig3d_Sinusoidal_PopReg_100ms. Normalized ensemble population signals during muscle stretch in the sinusoidal task. Data down-sampled using a moving average window of 100 ms.

Sheet8: Fig4_Comp_Coeffs_Across_Tasks. r2 values across afferents describing the relationship between spindle afferent firing and press force in the isometric condition and the relationship between spindle firing and joint angle/velocity in the sinusoidal condition.
