Design and development of a smart knee pain relief pad based on vibration and alternate heating and cooling treatments

Knee pain is one of the main health issues faced by different people in different parts of the world. Over one fourth of the people above the age of fifty suffer from knee pain. Though there are several physiotherapy treatments for treating knee pain they are not self-applicable and those which are self-applicable by the patient are not highly efficient. This paper deals with an approach towards the use of combining two effective physiotherapy treatments which include vibrations at acupressure points on knee and alternate heating and cooling treatments. These treatments are controlled by a smart phone in which the user can choose their setting depending on intensity and places of pain. The knee pad controlled using the smart phone serves as a self-applicable and effective knee pain treatment especially for the elderly. Heating and cooling combination therapy will be a suitable alternative for treatment of musculoskeletal diseases, decreases muscle spasms, muscular pain/tension and also increases the speed of nerve conduction, thus improving range of motion. This methodology also helps to relieve the sinusitis pain, chronic low back pain and muscular sprain in athletes.
