The first validated effort test for monitoring Vitality Capacity* in less than 5 minutes

* As defined by WHO: Vitality Capacity is a physiological state ... reflected in the level of 
  (1) energy and metabolism, (2) neuromuscular function, and (3) immune and stress responses.

Eforto® is the first validated solution to monitor 

1. Muscle strength - maximal grip strength test

2. Muscle fatigability - fatigue resistance test

3. Self perceived fatigue - questionnaire

as biomarkers for Vitality Capacity* as defined by the WHO 

*Vitality Capacity is a physiological state ... reflected in the level of 
(1) energy and metabolism, (2) neuromuscular function, and (3) immune and stress responses.

Eforto® is the first validated solution to monitor key biomarkers of Vitality Capacity as defined by WHO 

1. Energy and metabolism: Muscle fatigability and Self-perceived fatigue​

2. Neuromuscular function: Grip strength, an essential biomarker for overall strength

With a validated test protocol in less than 5 minutes

We enable Healthy Ageing with insightful metrics

Our mission

 We enable healthy longevity by making monitoring physical reserves and vitality capacity available to everyone.

Clinical Research

Eforto revolutionizes clinical research by making it easy to collect biomarkers for physical reserves and vitality as defined by the WHO. It includes outcomes from grip strength, muscle fatigability, and self-perceived fatigue Additional questionnaires or data capture can be added on demand.  
Perform validated assessments during visits or opt for remote self-monitoring.


Proactively monitor and detect a decline in physical reserves and vitality capacity before the person starts feeling it. Allowing a timely intervention before the onset of frailty.


Use objective biomarkers of Vitality Capacity to monitor rehabilitation, tracking individual responses and recovery across various treatments, medications, nutrition plans, physical therapy, and coaching.

The Eforto System

The Eforto System enables the monitoring of grip strength, muscle fatigability, and self-perceived fatigue—key biomarkers for assessing vital capacity in prevention, rehabilitation, and clinical research.
This user-friendly system offers accurate and reliable data through its three main components:

Ergonomic Dynamometer: Superior usability and performance.

Eforto Mobile App: Validated self-testing in just 3 to 5 minutes.

Remote Monitoring Platform: Insightful metrics and data exchange.

Ideal for home and clinical settings, the Eforto System combines advanced technology with ease of use. Its portability and quick assessments ensure convenient health monitoring, while robust data reporting and integration options enable better decision-making and improved health outcomes. Experience the future of Vitality monitoring with Eforto—where innovation meets simplicity.

The Eforto system is designed and validated to monitor grip strength, muscle fatigability and self-perceived fatigue as biomarkers for Vitality Capacity in prevention, rehabilitation, and clinical research. 

The Eforto System consists of a portable, user-friendly dynamometer which seamlessly connects to the Eforto mobile app for interactive guided self-tests, enabling both self-monitoring ay home or caregiver-assisted assessments.

Our fully digital system captures and stores data securely on our Remote Patient Monitoring (RPM) platform for reporting, with integration options for data exchange. Continuous improvements to our algorithms through machine learning and an expanding library of tests ensure the Eforto system remains future-proof.
