What is DynaMo?
VALD’s DynaMo Handheld Strength & ROM system is a range of innovative, all-in-one devices that combine the functionalities of a handheld dynamometer (HHD) and an inclinometer, making them versatile tools in performance and healthcare settings. DynaMo’s technology delivers precise and consistent measurements of muscle strength and range of motion (ROM). This dual capability sets them apart from other handheld dynamometers (HHDs), which typically only measure muscle strength.
DynaMo’s modular attachments and user-friendly interface enhance the accuracy, efficiency and versatility of assessments for a range of populations, including athletes, people with injuries, youth and older populations.
What makes DynaMo different than other HHDs?
DynaMo’s modular design and advanced hardware go beyond typical HHD capabilities by combining force and inertial measurement into one system. DynaMo is capable of over 300 tests, which can be performed as handheld, fixed to a wall, bed or cable for additional reliability or even attached directly to a patient’s limb.
The software that powers DynaMo (the DynaMo apps for Android and iOS, plus VALD Hub) further distinguishes it from other devices. The DynaMo app logs results automatically, reducing the need for handwritten notes. The real-time strength and ROM visualisations provided by the DynaMo app further enhance the user experience, gamifying assessments and making them more interactive.
Most importantly, all DynaMo data is automatically synced to VALD Hub alongside other assessment information such as patient-reported outcome measures (PROMs), exercise programs and results from other VALD systems, such as ForceDecks, NordBord, ForceFrame, SmartSpeed, and HumanTrak.
DynaMo’s cohesive system not only helps streamline practitioners’ workflow but also builds confidence in the data they collect, facilitating data-informed decision-making for profiling, monitoring, training, rehabilitation and more.
What does DynaMo measure?
DynaMo measures the physical force that muscles exert onto its load cell sensor and quantifies this force in newtons (N), kilograms (kg) or pounds (lb). This force is indicative of the muscle’s strength. DynaMo also measures joint ROM using a 9-axis inertial sensor (IMU), which provides detailed insights into linear and rotational movement.
This combination of strength and ROM measurement capabilities makes DynaMo a comprehensive yet affordable tool for assessing musculoskeletal function, making it ideal for practitioners looking for a versatile, accessible entry point into high-quality dynamometry.
In addition to force, DynaMo also assesses metrics such as:
Understanding these metrics is crucial for practitioners and patients. By leveraging advanced algorithms and insights from other VALD technologies, such as ForceDecks, DynaMo is able to offer a detailed analysis of physical capabilities. This aids in identifying deficiencies, optimising performance, preventing injuries and facilitating effective training and rehabilitation.
What DynaMo models are available and how do they differ?
VALD offers three DynaMo models, each catering to different functional needs:
Key specifications for each model are listed here:

What tests can DynaMo perform?
DynaMo performs a wide variety of tests, making it an invaluable device for comprehensive evaluations. Here’s a breakdown of the testing capabilities for each model:
The DynaMo range not only provides comprehensive analyses of these test types but also offers the ability to create and save a battery of tests that can be performed in quick succession.
How do practitioners ensure their DynaMo results are accurate?
Inspired by the development of ForceFrame, VALD designed the DynaMo range to provide a versatile and reliable tool for strength and ROM testing.
While the shift from analog to digital models has improved reliability and user experience, many HHDs still face challenges due to human error. This is particularly true in compressive muscle testing, where assessors must apply equal and opposite forces to the testing limb, leading to variable results based on the strength of both the assessor and the patient.
The DynaMo range includes various attachments and testing modes to enhance measurement accuracy and reliability. DynaMo Lite features compression and fixed-point options, while DynaMo Plus and Max add tension testing to their capabilities. These features help practitioners minimise human error and ensure that the data collected is precise and consistent.
The DynaMo app also provides detailed test protocols for all three models, covering a wide range of body parts and test types to help practitioners achieve accurate and reliable results.
Explore the test protocols tailored for each DynaMo model:
To achieve the most accurate and consistent results with DynaMo, practitioners should follow these best practices during testing:
- Zero the device before each test – Ensure the DynaMo is zeroed in its testing position with no load applied to eliminate baseline measurement errors.
- Stabilise the device during testing – Keep the DynaMo as stable as possible to avoid movement or shaking that could affect readings.
- Maintain proper alignment – Ensure the DynaMo is perpendicular to the limb applying the load, as non-perpendicular forces may not be accurately registered.
- Use fixed-point testing when possible – Anchoring the device to a solid object reduces variability introduced by the assessor’s strength and stability.
- Follow in-app prompts and protocols – The DynaMo app provides real-time prompts and detailed protocols to guide practitioners through each step, ensuring tests are performed correctly and data is accurately captured.
What is a good strength score for common DynaMo tests?
A good strength score for common DynaMo tests can vary based on individual factors such as age, gender, sport and fitness level.
Practitioners can utilise DynaMo’s in-app Norms and integrated normative data in VALD Hub to benchmark and interpret results effectively. These Norms provide access to a comprehensive database of normative data, allowing practitioners to compare individual test scores against population averages.
This helps practitioners identify strengths and weaknesses, set realistic goals and track progress over time.
