Tissue treated in cold-water immersion remains cooler significantly longer which translated means a better therapeutic treatment. However, patients tend to have an aversion to full foot immersion because of the cold discomfort to the toes (personal clinical experiences). The most common method of reducing the toes discomfort is to apply a ‘toe cover’, which reduces the amount of cold water reaching the toes, but many patients still prefer ice bags. The AnkleAid is a single foot cold-water immersion device, which features a preformed area for placing the injured foot, which ensures a 360 degree cold-water immersion and keeps the toes out of the water for patient comfort. The application of cryotherapy ranges from acute injury (e.g. ankle sprains), gout, malleolar fractures, rheumatoid arthritis, plantar fasciitis, achilles tendonitis post surgical and post rehabilitation therapy.
