Phyx.io is a comprehensive physical activity monitoring platform specifically devoted to support remote rehabilitation. On the one hand, Phyx.io provides an information system in which all data related to the rehabilitation process is being managed. This involves the different roles that participate in the rehabilitation process, such as the healthcare facility, the physiotherapist, or the patient. This also involves the exercise routine prescribed to the patient along with the data regarding the performance achieved in each session. This data enables physiotherapists to assess, in a more quantitative manner, the evolution of each patient. It also helps evaluate the patient adherence to the program. Furthermore, feedback is provided to the users while performing the exercises.

Phyx.io is equipped with its own video call system integrated into the system. The user can contact its physiotherapist, if necessary, in just one touch on the screen. Phyx.io also integrates the use of smart bands and enables and automatic mechanism to retrieve the information from a commercial smart band (e.g., Xiaomi MiBand 4), with a point-to-point connection avoiding the commercial cloud of the smart band vendor. Data is incorporated into the user profile and can be accessed through the Phyx.io dashboard. In this way, both healthcare specialists and users can analyse, in a glimpse, some factors that determine the physical activity level such as the number of steps, calories burnt, heartrate, etc.

There are different features that make Phyx.io a breakthrough in the state of the art for remote rehabilitation. Most of the commercial solutions for performing rehabilitation exercises at home are based on the use of Apps which display videos, but do not perform any body tracking. The performance monitoring is only based on the feedback self-reported by the user. On the other hand, at a research level, there are many solutions based on depth cameras that are expensive and hard to deliver and run in a home-based environment. Phyx.io overcomes these two limitations by providing an accurate body pose estimation system that tracks the performance of exercises, in terms of number of repetitions, achieved joint range of motion, or required time. The hardware setup required to run the system is very versatile as different options are offered (large smart mirror, small smart mirror or TV-based kiosk).
