A Smart Wearable Device for Monitoring Low Back Pain Rehabilitation

Currently, assessment and evaluation of low back pain (LBP) are based on

questionnaires on patients’ levels of pain and discomfort. This qualitative

assessment can be highly subjective with limited accuracy in accessing the

progress of rehabilitation.

Thus, a smart wireless Electromyography (EMG) device integrated with a

smartphone-based application is developed to monitor the progression of low back pain rehabilitation. The evaluation algorithm implemented on an Android smartphone application determines improvement in muscle performance.

The system consists of EMG acquisition hardware in conjunction with signal

processing and analysis software applications on android smartphones. The device acquires EMG signals from erector spinae (ES) muscles at L4 and L5 lumbar regions. The signals are then processed, amplified, and sent to the microcontroller for analog-digital conversion. Real-time EMG signals are sent wirelessly to smartphone-based clinical applications. The transmitted EMG signals of ES muscles are stored in the application and used to calculate Flexion Relaxation Ratio (FRR) and Extension Relaxation Ratio (ERR). FRR and ERR values are compared before and after interventions to analyze muscle performance.

These values are used to analyze, evaluate and monitor the progression of LBP rehabilitation.
