Effect of socks on the assessment of vibration sensation.

Meral RC, Matur Z, Dertsiz B, Oge AE - ISRN Neurol (2013)

Bottom Line: No significant difference was found between the measurements without and with socks, except those found at the MM in group H (P = 0.02).This significant difference was further analyzed in terms of effect size which was concluded to be practically insignificant (Cohen's d < 0.2).Conclusions.

ABSTRACT
Objective. To investigate the difference between the measurement of vibration sensation without and with socks. Material and Methods. Fifty healthy volunteers (H group) and 19 patients with diabetic polyneuropathy (PNP group) were included. The sites of measurement were the great toe (GT) and medial malleolus (MM). A standard 128 Hz tuning fork was used in the measurements. Results. Mean duration of vibration sensations without and with socks was as follows: in the H group, 19.4 ± 4.2 and 19.5 ± 4.2 s at GT and 15.1 ± 3.3 and 14.6 ± 3.3 s at MM; in the PNP group, 13.4 ± 3.8 and 12.7 ± 4.1 s at GT and 11.9 ± 3.8 and 11.7 ± 3.4 s at MM. No significant difference was found between the measurements without and with socks, except those found at the MM in group H (P = 0.02). This significant difference was further analyzed in terms of effect size which was concluded to be practically insignificant (Cohen's d < 0.2). Shorter mean vibration duration was measured at MM as compared to GT that could be explained by the damping effect. Conclusions. Wearing socks of moderate thickness does not have any important effect on the duration of vibration sensation. This might be considered as a reflection of the remarkable properties of vibration sensation.

Mentions: The positions of the subjects' feet during measurements are shown in Figure 1. Four sites were selected for measurements: dorsum of the interphalangeal joint of the great toe (GT) and the vertex of the medial malleolus (MM) on both sides. The tuning fork was applied vertically to these points with gentle pressure after the prongs were maximally activated (by tapping the prongs against the examiner's hypothenar eminence) for each measurement (Figure 1). Two investigators took the measurements; the first one applied the tuning fork while the second investigator measured with a stopwatch the duration of vibration sensation from the activation time of the tuning fork until the subject's verbal indication that the sensation was over.
