‘Bones’ is an orthopedic cast with sensors for capturing muscle activity. It is supported by a community-based website for cast users and those who track their mobility and recovery achievements.Bones is designed by Pedro Nakazato Andrade ,a Brazililian designer whose area of expertise is Product design & interaction design.

After a fracture, the patient goes to the Hospital to be analysed and receives the proper treatment by their doctor. There they are presented with Bones. Each time the user turns on Bones, all the muscle activity around the fracture area is captured by electromyographic (EMG) sensors and stored in the cast device.

The process of recovering from a fractured Bone is not limited only to the period spent with the cast, but to the entire mobility 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.

The goal of bones is to offer concrete information and a sense of achievement according to the level of exercise that users do during the cast period. Based on all the physical activity data of the patients, Bones simulates the time reduced from the users full mobility and muscle strain recovery treatment.
