Immediate Effects of Low-Intensity Plantar Proprioceptive Stimulation of the Affected Limb on Stable Versus Unstable Surfaces on Modified Sit-to-Stand Time and Gait Following Total Knee Arthroplasty
Sponsor: Sahmyook University
Summary
This randomized controlled study will investigate the immediate effects of low-intensity plantar proprioceptive stimulation performed on an unstable versus stable surface in patients during early rehabilitation after unilateral total knee arthroplasty (TKA). Participants will be randomly assigned to either an unstable-surface group or a stable-surface group. While seated, participants will apply low-intensity pressure through the operated foot using a standardized repeated pressing task. The unstable-surface group will perform the task with the operated foot placed on a balance pad, whereas the stable-surface group will perform the same task on a firm surface. The primary outcome will be the time required to perform a modified sit-to-stand task. Secondary outcomes will include walking performance, pain, and knee range of motion. The study aims to determine whether providing additional plantar proprioceptive input through an unstable surface can produce an immediate improvement in functional performance during early rehabilitation after TKA.

Interventions
Low-Intensity Plantar Proprioceptive Stimulation on an Unstable Surface
Participants will perform low-intensity plantar proprioceptive stimulation while seated with the operated foot placed on a balance pad. They will apply low-intensity pressure through the operated foot for 5 seconds followed by 5 seconds of relaxation. The cycle will be repeated 12 times for approximately 2 minutes.
Low-Intensity Plantar Proprioceptive Stimulation on a Stable Surface
Participants will perform the same low-intensity plantar proprioceptive stimulation while seated with the operated foot placed on a firm surface. They will apply low-intensity pressure through the operated foot for 5 seconds followed by 5 seconds of relaxation. The cycle will be repeated 12 times for approximately 2 minutes.
