Maintaining posture relies on integrating information from multiple senses that tell the brain where the body is and how it’s moving. Vision provides a reference frame and detects movement of the surroundings relative to you. The vestibular system in the inner ear senses head position and acceleration, helping detect sway and maintain balance even when vision is limited. Proprioception from muscles, tendons, and joints gives detailed feedback about the position and movement of each body part. The brain combines these cues and adjusts muscle activity to keep you upright; it can reweight the inputs depending on what's reliable in the moment. For example, in darkness the body leans more on proprioceptive and vestibular information, while in a moving environment vision can contribute but may also mislead if the scene itself moves. Because all three systems contribute to posture control, the best answer is that all of the above.
