How long can joint position sense be retained in memory by young healthy subjects?

Xie D, Urabe Y - J Phys Ther Sci (2014)

Bottom Line: [Purpose] The aim of the present study was to investigate how long joint position sense (JPS) can be retained in memory. [Subjects] Eleven healthy subjects (5 men and 6 women) were enrolled in this study. [Methods] Subjects memorized a specific joint position visually, and then they were asked to reproduce without visual aid the position at 3 different time intervals: immediately, 5 minutes post-memorization, and 30 minutes post-memorization. [Results] Differences in JPS between time intervals of immediate and 30 minutes post-memorization were statistically significant with the exception of knee flexion at 60° with a 5 kg load.Differences in reproduced JPS between time intervals of immediately and 5 minutes post-memorization were not statistically significant. [Conclusions] The results suggest that JPS can be retained in memory for approximately 5 minutes.

Mentions: JPS was evaluated using a Monitored Rehabilitation Systems Functional Squat System(MFSS). The MFSS is a software system capable of evaluating the position sense of thelower extremity throughout the concentric and eccentric phases of motion, duringfunctional squat movements (Fig. 1aFig.1.
