Assessment

Primary outcomes

First, head MRI images of the subjects are acquired. Next, visual tracking and joint position sense tasks are performed to assess ankle joint function. The interval between the head MRI scan and the performance of each task should be within one week. Brain imaging data is acquired using a 32-channel head coil (QD coil, 32-channel Head SPEEDER Coil) and a 3T Vantage Galan MRI scanner (Canon Medical Systems, Tochigi, Japan). The acquired images include T1-weighted images, T2-weighted images, and resting-state functional images.

Key secondary outcomes

In the visual tracking task, we used waveform offset detection software (S-17526, Takei Kiki Kogyo) and an AD converter (TSA-210, Takei Kiki Kogyo) to record the plantar flexion and dorsiflexion angles of the right ankle at a sampling frequency of 100 Hz. We instructed the subjects to track the target waveform on the monitor by voluntarily adjusting the ankle angle. Defining 10 degrees plantar flexion as 0% and 20 degrees dorsiflexion as 100%, sinusoidal waveforms combining three angle ranges (0-60%, 0-70%, 0-80%) and two duration settings (2.5 seconds, 5 seconds) were presented randomly. The task consisted of three trials, each lasting 60 seconds.
For the joint position sense task, we used the PowerLab signal analysis system (AD Instruments) and LabChart 8 (AD Instruments) to record the dorsiflexion and plantarflexion angles of the right ankle at a sampling frequency of 4000 Hz. The subject was instructed to reproduce the passively presented right ankle angle through active movement; the presented angles were set to three conditions (ankle in plantar flexion at approximately 0 degrees, 10 degrees dorsiflexion, and 20 degrees dorsiflexion). A total of 15 trials were conducted in random order, with five trials for each angle.
