A carefully planned, structured, and supervised physiotherapy program, following a surgery, is crucial for the successful diagnosis of physical injuries. Nearly 50% of the surgeries fail due to unsupervised and erroneous physiotherapy. The demand for a physiotherapist for an extended period is expensive to afford, and sometimes inaccessible. With the advancements in wearable sensors and motion tracking, researchers have tried to build affordable, automated, physio-therapeutic systems, which direct a physiotherapy session by providing audio-visual feedback on patient’s performance. There are many aspects of automated physiotherapy program which are yet to be addressed by the existing systems: wide variety of patients’ physiological conditions to be diagnosed, demographics of the patients (blind, deaf, etc.,), and pursuing them to adopt the system for an extended period for self-care
Objectives and Solution:
In our research, we have tried to address these aspects by building a health behavior change support system called KinoHaptics, for post-surgery rehabilitation. KinoHaptics is an automated, persuasive, haptic assisted, physio-therapeutic system that can be used by a wide variety of demographics and for various patients’ physiological conditions. The system provides rich and accurate vibro-haptic feedback that can be felt by any user irrespective of the physiological limitations. KinoHaptics is built to ensure that no injuries are induced during the rehabilitation period. The persuasive nature of the system allows for personal goal-setting, progress tracking, and most importantly lifestyle compatibility.
Evaluation and Results:
The system was evaluated under laboratory conditions, involving 14 users. Results show that KinoHaptics is highly convenient to use, and the vibro-haptic feedback is intuitive, accurate, and definitely prevents accidental injuries. Also, results show that KinoHaptics is persuasive in nature as it supports behavior change and habit building.
The successful acceptance of KinoHaptics, an automated, haptic assisted, physio-therapeutic system proves the need and future scope of automated physio-therapeutic systems for self-care and behavior change. It also proves that such systems incorporated with vibro-haptic feedback encourage strong adherence to the physiotherapy program; can have a profound impact on the physiotherapy experience resulting in higher acceptance rate.
