Chronic ankle instability (CAI) is characterised by recurring “giving way” of the outer ankle with general movements following a history of recurrent ankle sprains. Complex Regional Pain Syndrome (CRPS) is progressive pain syndrome developing often after trauma and is characterised by: a) continuing pain that is disproportionate to the original event and b) displaying the presence of sensation, movement and circulatory changes which often cannot be easily explained.
Recurring ankle injuries resulting in ongoing ligament and muscle weakness and poor proprioception. Often initiated by poor rehabilitation in the first instance.
Signs & Symptoms:
(CAI) Pain and tenderness, persistent discomfort and swelling, repeated turning or “giving way” of the ankle. Significant ligament laxity to the lateral ankle ligaments. (CRPS) Disproportionate pain, hypersensitivity, oedema and sweating, temperature and colour changes, decreased range of motion, or movement dysfunction.
Following correct diagnosis of the condition treatment will either consist of a progressive conservative rehabilitation strengthening and proprioceptive/ balance training program to assist with CAI. CRPS involves an integrated pain management approach inclusive of education, medication and specific physiotherapy intervention.
Chronic ankle instability and Complex regional pain syndrome treatment programs may take up to 6 months to see clear improvements in impairment.
