Ankle Sprain and Chronic Lateral Ankle Instability: Optimizing Conservative Treatment
Abstract
A modernized rehabilitation framework for ankle instability, advocating for the shift from RICE to PEACE and LOVE. The review outlines a structured 4-phase protocol emphasizing early loading, proprioception, and peroneal strengthening to prevent chronic instability.
R.I.C.E. is Dead: Enter PEACE and LOVE
Key Finding
"Evidence suggests replacing passive Rest/Ice with active Protection, Elevation, Avoid NSAIDs, Compression, Education (PEACE) and Load, Optimism, Vascularization, Exercise (LOVE) to optimize tissue healing."
Background: Up to 70% of acute ankle sprains progress to Chronic Lateral Ankle Instability (CLAI) due to inadequate initial management. The traditional RICE protocol (Rest, Ice, Compression, Elevation) focuses excessively on acute symptom control rather than tissue regeneration and proprioceptive recovery. A paradigm shift was required to integrate soft tissue healing biology with aggressive functional rehabilitation.
Methods: The authors reviewed current evidence to propose an optimized Stepladder Approach to rehabilitation. The protocol is divided into four phases: Acute (Protection/PEACE), Subacute (Range of Motion/Strength), Advanced (Proprioception/Balance), and Return to Sport. The review also evaluates the efficacy of immobilization tools (Aircast vs. casts) and adjuncts like wobble boards.
Results: Strict immobilization should be reserved only for severe soft tissue injury; functional bracing (e.g., Aircast) yields superior outcomes for moderate sprains. The review highlights that Rest should be replaced by Optimal Loading to stimulate collagen repair. For chronic instability (CLAI), proprioceptive retraining (e.g., wobble board, trampoline) and peroneal strengthening are the cornerstones of non-operative success, significantly reducing recurrence rates.
Conclusion: Passive management of ankle sprains breeds chronic instability. Clinicians must adopt the PEACE and LOVE protocol immediately, transitioning patients rapidly from protection to proprioceptive dominance. Surgery should be reserved only for those who fail this optimized, active-loading regimen.
