Patent Application

The present disclosure relates to a system, an apparatus and a method to train a subject. More particularly, the present disclosure relates to the system, apparatus and method for training the subject by monitoring health of the subject.
While a subject undergoing through intensive bodily regimes such as professional sports, exercises and/or physiotherapy then there are certain body movements that can be associated with the subject. For instance, an injured subject (patient) while undergoing physiotherapy courses, must know the accurate body movements to rectify the impaired body region.
Physiotherapies are crucial exercises/body movements that improves quality of life of the subject. In order to get a proper guidance for executing such body movements, a physiotherapist or any other medical personnel assist the patient/user to avoid any damaging movement regarding the impaired body region.
To realize the interaction of the physiotherapists or mimicking the assistance of physiotherapists, there are certain techniques known in the art that enables remote physiotherapy. Techniques like virtual reality and augmented reality are employed for delivering physiotherapies, exercises, or training, which ropes in minimal interaction of the physiotherapists while delivering such exercises remotely. Remote physiotherapy consumes less time in delivering the exercise guidance and enables the physiotherapists to cater to multiple subjects at a time or at different time frames.
One of the drawbacks associated with the remote physiotherapies incorporated with techniques such as virtual reality and augmented reality is the lack of instant real-time communication with the subject/patient to stop exercise or sports activity in case of any wrong body movement being carried out by the subject. Further, the remote physiotherapies may be proven dangerous for the subjects upon not getting notified for any inaccurate body movement. Due to damaging effects of such body movements, the affected body part of the patient/user may get permanently damaged, thus affecting the proper usage/employing of remote physiotherapies. Furthermore, there remains a significant risk of putting patients in an augmented reality or virtual reality game due to lack of communication with the subject/patient. For instance, this lack of communication with the patient may lead to dislodgment of the blood line during movement of the hand of the patient/user while performing dialysis on the patient. The physical presence of trained clinical professional not only watches for the damaging movements but also observes for subtle signs of clinical deterioration of the patient, these signs are generally not available during remote physiotherapies.
The available methodology of studying the pulse segment for multiple beats and then studying the heart rate variability requires at least 30 seconds of data before physiological change can be predicted, which limits instant communication with the user, during session of remote physiotherapy. In an example, while performing a dialysis procedure on the user, it requires an appropriate hand position of the user to circulate the blood from the hand of the user to the dialysis machine. Due to the lack of instant communication, the hand movement can lead to dislodgment of the blood line of the user and may lead to exsanguination and death of the user.
Thus, there is a need for a technical solution that overcomes the aforementioned problems of techniques involved in remote physiotherapy.

This regulation of the game speed facilitate protection for the user that prevents any dislodgement of the blood-access of the hand that is involved in the dialysis procedure.
In operation, the system (100) monitors the physiological state of the user, while the user is performing the exercise on the exercising apparatus (200). Based upon the instruction signal (118A) generated by the instruction engine (118), the regulating unit (108) may be adapted to regulate the speed of the exercising apparatus (200) and thereby controlling the rate of exercise being performed by the user. The speed or resistance of the exercising apparatus may be, therefore: regulated as per desired sympathetic and parasympathetic ratios associated with the user. The resistance of the exercising apparatus may be, therefore: regulated as per the desired cardiovascular parameter for the user as set by the clinical provider. The adjustments can be based on the known condition of the patient based on the age, medical condition, disease state and baseline physiological stress. The adjustments can be based on the dynamic physiological stress experienced by the patient and detected by the sensors as he/she undergoes a particular exercise.

In another embodiment, the number of sensors (112) may be adapted to detect chest expansion of the user, while the user may perform deep breathing exercises. The detection of chest expansion of the user may indicate breathing rate. The system (100) may be adapted to alter/regulate the game based on the measurement of the chest expansion of the user and thus encourage the user to continue to take deeper breaths for enhancing a pulmonary function of the user. The system (100) may be adapted to alter the game based on the user's clinical condition and thereby select and automate an appropriate physiotherapy treatment for the user. Upon selection of the appropriate physiotherapy treatment, the exercise may be tailored as per the clinical condition of the user.
