The Eforto® system enables monitoring of [grip strength](https://www.eforto.com/grip-strength?hsLang=en), [muscle fatigability](https://www.eforto.com/muscle-fatigability?hsLang=en), and self-perceived fatigue - key biomarkers for assessing [vitality capacity](https://www.eforto.com/vitality-capacity?hsLang=en) - through a simple, guided 5-minute effort test. Whether you're a healthcare provider, researcher, health coach, or an older adult, Eforto delivers instant, objective insights in prevention, triage, rehabilitation, disease management and clinical research. These insights capture essential aspects of neuromuscular health and energy metabolism, which are key indicators of body resilience, early signs of frailty and potential low-grade inflammation. ** **   ### One System: Three Powerful Components ![Grip Release - Round_Icon](https://www.eforto.com/hubfs/Eforto-2025/image/Grip%20Release%20-%20Round_Icon.svg) ##### Eforto® Vigorimeter ergonomic handgrip device for measuring strength and endurance ![Mobile_App - Round_Icon](https://www.eforto.com/hubfs/Eforto-2025/image/Mobile_App%20-%20Round_Icon.svg) ##### Eforto® Mobile App guides validated self-tests and visualizes  test results ![Metrics Platform - Round_Icon](https://www.eforto.com/hubfs/Eforto-2025/image/Metrics%20Platform%20-%20Round_Icon.svg) ##### Eforto® Metrics Platform secure remote monitoring and analytics dashboard #### We make monitoring physical reserves as convenient and routine as measuring blood pressure [View Full Eforto® Test](https://www.eforto.com/system#modal_col-num-1_module_1754635046073_2) ![Eforto-Vigorimeter_Rounded_1](https://www.eforto.com/hs-fs/hubfs/Eforto-2025/image/Eforto-Vigorimeter_Rounded_1.png?width=600&height=600&name=Eforto-Vigorimeter_Rounded_1.png) ### Eforto® Vigorimeter Outperforms traditional dynamometers ![Superior ergonomy - white Icon](https://www.eforto.com/hs-fs/hubfs/Eforto-2025/image/Superior%20ergonomy%20-%20white%20Icon.png?width=64&height=64&name=Superior%20ergonomy%20-%20white%20Icon.png) #### Superior ergonomy The ergonomic bulb is superior compared to classic isometric dynamometers. - More reliable across different handsizes - Allows sustained grip strength test to assess muscle fatigability ![Usable by the weakest - white Icon](https://www.eforto.com/hs-fs/hubfs/Eforto-2025/image/Usable%20by%20the%20weakest%20-%20white%20Icon.png?width=64&height=64&name=Usable%20by%20the%20weakest%20-%20white%20Icon.png) #### Usable by the weakest With only 100g, Eforto is usable by even the weakest persons. ![High Accuracy - white Icon](https://www.eforto.com/hs-fs/hubfs/Eforto-2025/image/High%20Accuracy%20-%20white%20Icon.png?width=64&height=64&name=High%20Accuracy%20-%20white%20Icon.png) #### High accuracy Medical grade pressure sensor with auto-calibration before each test.

This approach removes the hidden biases found in traditional dynamometers, giving clinicians, researchers, and patients an anatomically balanced and replicable measure of true muscle health. - Hand-size Neutrality - Ergonomics That Fit Users - Consistent Data to Trust ![Hand size bias - Image](https://www.eforto.com/hubfs/Eforto-2025/image/Hand%20size%20bias%20-%20Image.svg) #### Results Stay Reliable Across Hand Geometries Eforto® ensures unbiased grip strength readings by keeping results consistent compared to normative data regardless of finger span, palm width, or hand length. Standardized handle geometry and surface contact ensure reliable results for the same muscle effort, enhancing fairness, clinical tracking, and data accuracy. Validation versus standard dynamometers confirms reliable, hand-size–neutral performance. ![handle limitations](https://www.eforto.com/hubfs/Eforto-2025/image/handle%20limitations.svg) #### Adaptable Grip Surface for Better Ergonomics Eforto®’s ergonomic, adaptable grip suits most hand sizes and conditions, ensuring comfortable, consistent strength testing for every user. Eforto®'s variable sensor contact zones, contoured edges, and natural curve minimize joint pressure and positioning errors. Better ergonomics boost comfort, reduce failed attempts, and improve first-measurement success, validated through usability studies. ![Anthropometry](https://www.eforto.com/hubfs/Eforto-2025/image/Anthropometry.svg) #### Replicable Data Across Every Measurement Eforto® ensures consistent, replicable results across users, clinics, and instruments for reliable grip strength tracking. Replicability comes from calibrated sensors, standardized measurement prompts, automated quality checks, and inter-device calibration aligned with clinical gold standards. Documented reliability and validity correlations of Eforto® confirm data accuracy that results in building trust. ### A New Era in Muscle Profile Assessment When it comes to grip strength testing, not all measurements are created equal. Sugiyama, T., Whitney, D.G., Schmidt, M., Haapala, H., Bowman, A., Peterson, M.D. and Hurvitz, E.A., 2024. Measuring grip strength in adolescents and adults with cerebral palsy in a clinic setting: Feasibility, reliability, and clinical associations. *Developmental Medicine & Child Neurology,* 66(1), pp.87-94. #### Why Dynamometers Don’t Tell the Whole Story Besides key biomarkers like Fatigability and CPV that traditional dynamometers miss to measure, their measurements are affected by important variables that introduce hidden bias, as supported by multiple peer-reviewed studies - Hand size bias - Fixed handle limitations - Cross-device inconsistency ![Hand size bias - Image](https://www.eforto.com/hubfs/Eforto-2025/image/Hand%20size%20bias%20-%20Image.svg) #### Hand size bias Larger hands can register higher grip force on a dynamometer, even if actual muscle strength isn’t greater. A 339-participant trial found readings from a dynamometer correlated with palm width, hand length, and forearm size *(Neumann, S., Kwisda, S., Krettek, C. and Gaulke, R., 2017. Comparison of the grip strength using the Martin-Vigorimeter and the JAMAR-dynamometer: establishment of normal values. in vivo, 31(5), pp.917-924.)* ![handle limitations](https://www.eforto.com/hubfs/Eforto-2025/image/handle%20limitations.svg) #### Fixed handle limitations The rigid grips and fixed spacing of many dynamometers can be uncomfortable for people with arthritis, smaller hands, or weaker strength, leading to underestimation. Research shows this design can compromise both comfort and accuracy. (Gränicher, P., Maurer, Y., Spörri, J., Haller, B., Swanenburg, J., de Bie, R.A., Lenssen, T.A. and Scherr, J., 2024. *Accuracy and Reliability of Grip Strength Measurements: A Comparative Device Analysis.* Journal of Functional Morphology and Kinesiology, 9(4), p.274.) ![Device and phone](https://www.eforto.com/hs-fs/hubfs/Eforto-2025/image/Device%20and%20phone.png?width=210&height=300&name=Device%20and%20phone.png) #### Cross-device inconsistency Even when reliable, different dynamometers often produce slightly different results, indicating a lack of validity. complicating comparisons in clinical or research settings. (Benton, M.J., Spicher, J.M. and Silva-Smith, A.L., 2022. *Validity and reliability of handgrip dynamometry in older adults: A comparison of two widely used dynamometers.* PLoS One, 17(6), p.e0270132. ### **Eforto®: Towards a comprehensive profile of muscle assessment, endurance, and perceived vitality**   ![Rate of Voluntary - Round_Icon](https://www.eforto.com/hubfs/Eforto-2025/image/Rate%20of%20Voluntary%20-%20Round_Icon.svg) ##### Capture Endurance, NOT just Peak Power While dynamometers only capture one-time grip strength, Eforto®’s power also captures how long strength is sustained, revealing muscular endurance and fatigue, not just maximal output. ![Grip Release - Round_Icon](https://www.eforto.com/hubfs/Eforto-2025/image/Grip%20Release%20-%20Round_Icon.svg) ##### Spotting Hidden Decline Early  Among octogenarians who didn’t report fatigue, those with lower Grip Work and CPV scores and higher self-perceived fatigue were more likely to be pre-frail, even though traditional strength tests appeared normal. ### The Connection Between Endurance and Lived Experience is Now Clear Eforto®’s multi-step grip strength test goes beyond a single snapshot, delivering a complete vitality profile that predicts fraility, measures strength, endurance, and recovery, helping detect changes that traditional tests often miss. ### Ready to monitor Vitality Capacity in just 5 minutes?
