Design & analysis of ankle foot orthosis for assisting car driver after ankle surgery

Car accidents often occur and normally affected the car driver’s foot and ankle. If it is involved surgery for the ankle treatment, the recovery process normally takes a long time. As a normal practice, ankle foot orthosis (AFO ) will be worn by an ankle injury patient for shorten the recovery proce...
