# Anatomical Exploration of the KI1 Acupoint: Implications for Medial and Lateral Plantar Nerve Stimulation

## TL;DR

This study explores the KI1 acupoint's anatomy and how stimulating it may improve balance and neurological function.

## Contribution

The study provides new anatomical insights into the KI1 acupoint's location and its potential mechanisms for neurological therapy.

## Key findings

- KI1 is located in the superficial and deep layers of the plantar foot near medial and lateral plantar nerves.
- Gender differences in KI1 location were observed due to variations in foot morphology.
- Stimulation of KI1 may enhance sensory feedback and improve balance and cognitive functions.

## Abstract

Background and Objectives: This study aims to identify the precise anatomical location and therapeutic mechanisms of the KI1 acupoint (Yongquan) in relation to foot muscles and nerves, known for treating neurological disorders and pain. Materials and Methods: Dissection of six cadavers at Chungnam National University College of Medicine examined KI1’s relation to the foot’s four-layer structure. Results: The KI1 acupoint was located in the superficial and deep layers of the plantar foot, adjacent to significant nerves like the medial and lateral plantar nerves. Differences in the acupoint’s exact location between genders were noted, reflecting variances in foot morphology. KI1 acupuncture was found to stimulate the muscle spindles and nerve fibers essential for balance and bipedal locomotion. This stimulation may enhance sensory feedback, potentially improving cognitive functions and balance control. Conclusions: This anatomical insight into KI1 acupuncture underpins its potential in neurological therapies and pain management.
