Learning Objectives:

1. Analyze how individuals with CAI differ from healthy controls in postural control responses when visual, somatosensory, and combined sensory feedback are disrupted at low and high levels during single-leg stance. 2. Explain the nonlinear balance decline observed in patients with CAI under low-level visual disruption and their preserved somatosensory organization strategies, and apply this understanding to develop appropriate sensory-targeted balance training strategies. 3. Justify the clinical importance of incorporating graded multisensory challenge progression in rehabilitation programs, based on evidence that patients with CAI exhibit greater deterioration under combined sensory disruption, highlighting the need to strengthen adaptive sensory reweighting strategies.

Keywords: Sensory integration; Sensorimotor control; Single-leg balance.
