Abstract

Objective Kyphosis is one of the common abnormalities of the Spine. However, correct preservationof the posture can play an important role in preventing and treating Kyphosis. Biofeedback systemsare among the methods used to prevent postural dysfunction. This study aimed to design a biofeedbacktool to prevent Kyphosis and evaluated Reliability and Validity of this tool. Materials & Methods total of 17 students aged between 18 and 30 years participated in the studyas inappropriately. In this study, a flexible ruler was used as a golden standard to measure thekyphosis. First, a microcontroller-based Kyphosis control biofeedback device was designed usinga flexural sensor. This device consists of a vibration generator that activates when microcontrollerdetects a kyphotic situation. In other words, by changing the physical condition, the flexural sensorresistance used in the smart Biofeedback tool changes accordingly and the data collected by theflexural sensor are converted into a voltage variation with a simple resistance circuit. The output ofthe flexural sensor is input to the microcontroller so that as soon as the microcontroller detects anincorrect physical condition, it sends a control signal (based on the predefined threshold for the microcontroller)in a vibration feedback. If the curvature value is more than the threshold and lasts forat least 30 seconds, it will alert the user with vibration feedback. Vibration alert continues as long asthe user is in the kyphotic situation and stops as soon as the user leaves the kyphotic situation andreturns to the natural state. After installing the designed Biofeedback tool on the target area of thebody, the tool error is evaluated by counting the number of warnings in the normal state and lackof warning in the kyphotic condition. In addition, to check the repeatability of the Biofeedback tool, measurements were made in two neutral conditions and a tissue for each situation twice, with adistance of 2 hours. In this research, the tool Validity was measured by Kappa coefficient based onsensitivity, specificity, and Reliability...
