Bones Orthopedic Cast with Sensors Records Muscle Activities Around Fractured Areas

Pedro Nakazato has designed Bones orthopedic cast with sensors to capture the muscle activities around the fracture area and stimulate full recovery time of the patient. The main objective of this project is to provide specific information and achievement of the patients based on their level of exercises during the cast period. Bones will simulate the time of recovery based on all the physical activity data of the patient.

Patients go to Hospital when they suffer from bone fractures to be analyzed and receive proper treatment from the doctor. They will be presented with Bones orthopedic cast. Each time the user turns on Bones, the EMG sensors will record all muscle activity around the fractured area and save the data in the cast device. All this information will then go into the community based website of Bones where Doctors, physiotherapists, and other new users of Bones can follow the patient’s progress. In this way, new users can visualize their achievement based on the data from former patients with the same type of fracture. Sharing this information is a good way to encourage other patients to engage with their recovery process from beginning of the treatment.

In the end, using Bones orthopedic cast can reduce the overall period of recovery time. Because the recovering process from a fractured bone doesn’t depend only on period spent with the cast but the entire activity and muscle strains recovery process. During the cast period the fractured limb loses huge amounts of muscle strain due to the inactivity of the area. One of the causes is that users start to exercise the limb only after removing the cast while they should be engaged in keeping the muscles around the fractured area active from the very first day with the cast.

For this project, the designer has done some research to decide the material for the cast. It has to be lighter, hygienic, and thinner compared to traditional material. He decided to use Polycaprolactone for the cast. The muscle sensors are embedded on the band which goes under the Bones orthopedic cast to keep the muscle tension around the fractured area.
