Intermediate Chronic Ankle Instability

A ~25-minute ankle stability routine focused on balance, calf strength, and controlled range of motion.

Targeting the Lateral Ligament Complex

Targeting the Lateral Ligament Complex

Band eversion and single-leg balance reach directly load the peroneals — the muscles most responsible for resisting inversion sprains. Ankle alphabet and circles restore synovial fluid distribution across the talocrural joint before any load is applied, reducing re-injury risk during the strength work that follows.

Why CAI Keeps Coming Back

Why CAI Keeps Coming Back

Chronic ankle instability isn't just ligament laxity — it's a neuromuscular deficit where mechanoreceptors in the lateral ligament complex stop firing accurately. The step down and single-leg RDL exploit perturbation-based loading to retrain proprioceptive feedback loops that standard strengthening alone never addresses.

Sensorimotor Sequencing Is the Strategy

Sensorimotor Sequencing Is the Strategy

This routine follows a mobility-to-stability-to-dynamic-load progression, which matches how the nervous system needs to be primed before proprioceptive training sticks. Increase the single-leg balance reach distance weekly as a simple progressive overload marker — when you can touch 90% of your leg length in all directions, advance to eyes-closed variations.
