Bio-Signals Processing &
Rehabilitation Robotics (BSRR) Lab

Welcome to BSRR Lab — where rehabilitation is engineered through biosignals.

Bio Signals Processing & Rehabilitation Robotics Lab. We listen to the human body — its muscles, heart, brain, and breath and turn what it tells us into rehabilitation technology.

Overview

Bio Signals Processing & Rehabilitation Robotics Lab. We listen to the human body — its muscles, heart, brain, and breath and turn what it tells us into rehabilitation technology.

The Bio-signals processing & Rehabilitation Robotics (BSRR) Lab is an interdisciplinary research group focused on the acquisition, analysis, and application of human physiological signals for advancing rehabilitation engineering and healthcare technologies. The laboratory is dedicated to bridging the gap between fundamental biomedical signal processing and real-world clinical rehabilitation needs. Welcome to BSRR Lab — where rehabilitation is engineered through biosignals.

Our work involves the use of both clinical-grade and advanced research instrumentation to acquire high-fidelity physiological data directly from human participants. These include surface electromyography (sEMG), electrocardiography (ECG), electroencephalography (EEG), respiratory signals, pulse measurements, blood pressure, and grip force dynamics. By integrating multimodal biosignal acquisition, we aim to capture a comprehensive understanding of human physiological responses under various conditions, particularly in rehabilitation and assistive scenarios. 

A central focus of the lab is the development of robust signal-processing pipelines and intelligent computational frameworks for extracting meaningful features from complex and often noisy biosignals. We employ advanced techniques from digital signal processing, statistical modeling, and machine learning—including deep learning approaches—to interpret physiological data with high accuracy and reliability. These methodologies enable us to identify patterns, assess functional recovery, and derive clinically relevant insights that can support diagnosis, monitoring, and therapeutic interventions. 

Positioned at the intersection of biomedical engineering, applied physiology, and computational intelligence, the BSRR Lab addresses critical challenges in rehabilitation science. Our research is driven by practical and translational questions: How can recovery be quantified more precisely and objectively? How can assistive and rehabilitative devices be controlled in a more intuitive and human-centric manner? And how can rehabilitation protocols be adapted dynamically to suit individual patient needs? 

Through this work, we aim to contribute to the development of personalized, data-driven rehabilitation systems that enhance patient outcomes, improve quality of life, and support clinicians in delivering more effective and responsive care. The lab also actively fosters collaboration across disciplines, encouraging innovation at the convergence of engineering, medicine, and human-centered design 

About

The BSRR Lab is exactly such a group. We acquire multi-modal physiological signals from human participants using clinical and research grade instrumentation, process them with modern signal-processing methods, and apply them to problems in rehabilitation engineering. Our work covers the full chain from electrode to algorithm to application. We are interested in research that is honest about real-world constraints: noisy signals, individual variability, limited data, and the gap between laboratory accuracy and clinical usefulness.

It is based in the School of Artificial Intelligence at Amrita Vishwa Vidyapeetham, Coimbatore.

Vision

To build a research environment where human bio signals, modern signal processing, and artificial intelligence come together to produce rehabilitation technology that is rigorous, reproducible, and clinically meaningful.

Mission

The lab works toward this vision through four commitments: 

  • Conduct rigorous human-subject bio signal research using clinical and research grade instrumentation and well-designed experimental protocols. 
  • Develop signal-processing and AI methods that are physiologically grounded, reproducible, and honest about their limitations. 
  • Translate findings into rehabilitation applications  assistive devices, therapy-monitoring tools, and quantitative clinical assessments. 
  • Train students who are fluent across the full pipeline, from electrode placement and protocol design to model deployment and clinical interpretation. 

Research Areas

The lab works on a range of problems around biosignals, rehabilitation, and human–machine interaction. Instead of fixed themes, our work is better described through the following focus areas: 

EEG-Based Brain Signal Analysis 

Studying brain activity to understand mental state during tasks, including stress, attention, workload, and engagement. This also includes exploring how brain activity relates to physiological responses during rehabilitation and interaction tasks.  

Surface EMG for Upper- and Lower-Limb Applications

Muscle signals are used for gesture recognition, prosthetic/orthotic control, and movement analysis. This includes both hand/wrist tasks and lower-limb activities like gait and sit-to-stand transitions.

EMG-Based Human–Machine Interaction

Using EMG signals to control assistive or robotic systems in a way that feels natural to the user, with a focus on real-time performance and usability.

Speech and Swallowing-Related Signal Analysis

Work on speech-related muscle activity and biosignals, including speech recognition using EMG and monitoring of neck muscle behaviour.

Neck Fatigue and Muscle Activity Monitoring

Studying muscle fatigue in the neck region during prolonged tasks, with applications in ergonomics, rehabilitation, and assistive support.

Cardiovascular Monitoring (ECG and PPG)

Using ECG and PPG to study heart activity and blood flow, including heart-rate variability, recovery patterns, and wearable monitoring approaches.

Multimodal Biosignal Integration

Combining EMG, ECG, PPG, EEG, respiration, and other signals to get a more complete understanding of human state during rehabilitation or interaction tasks.

Stress, Fatigue, and Engagement Assessment

Using physiological signals to estimate how a person is feeling and performing — including stress levels, mental workload, fatigue, and engagement.

Machine Learning for Biosignal Analysis

Applying machine learning and signal-processing techniques to interpret complex biosignals, with a focus on models that generalise well across users.


Image Processing for Biomedical Applications

Applying image-processing techniques to analyze visual data in healthcare and rehabilitation, including feature extraction, pattern recognition, and integration with biosignal data for improved assessment and monitoring.
