The devices that are currently being used for management of heel pain include kinesiology tape, in-shoe orthoses (in-soles) and silicone heel cups .
The kinesiology tape is a thin flexible tape that is used in the short term to reduce pain, increase the range of motion and increase proprioception of a joint or muscle group. In-shoe orthoses are a common treatment and management option for heel pain. They are custom made insoles that are inserted in the shoe of the patient to relieve pain during walking but are expensive and a given orthosis can only be used with a specific shoe design to ensure the intended benefits are realized. Silicone heel cups only support the heel as opposed to in-shoe orthoses which support the entire foot. The heel cups reduce heel pain by reducing the internal stresses of the heel pad by increasing its thickness.
Other treatment modalities include rest, stretching and use of anti-inflammatory drugs. Some of the anti-inflammatory drugs used include steroid injections, and oral and topical non-steroidal anti-inflammatory drugs (NSAIDs). The steroid injections are administered only once while topical and oral NSAIDs are required to be administered continuously over a given period. Long term use of oral NSAIDs can lead to serious gastrointestinal side effects, while steroid injections increase the risk of fat pad atrophy.
However, stretching of the plantar fascia provides a more significant improvement in the heel pain condition when compared to the other treatment modalities. Therefore, there is a need for a device that readily provides the stretching of the plantar fascia of the heel pain patient as they perform their day-to-day activities.
