Measure Shoulder Strength Objectively and Efficiently

Assess, Track, and Strengthen: A Smarter Approach to Shoulder Rehab

Shoulder pain is one of the most common complaints in both clinical and sports settings, and it’s often directly linked to weakness in the rotator cuff. Whether this weakness is the cause or the consequence of pain, what matters is having an accurate, objective way to measure it.

The rotator cuff (subscapularis, supraspinatus, infraspinatus, and teres minor) plays a central role in shoulder stability and rotation. These muscles are sensitive to load variation, making it essential to assess and monitor their strength throughout rehabilitation. Yet, without reliable tools and standardized protocols, these assessments can be inconsistent and lead to rehabilitation plans based on impressions rather than facts.

Handheld dynamometry has proven to be a valid and practical alternative to isokinetic testing. Studies show high intra- and inter-rater reliability, especially for internal and external shoulder rotation (Cools, 2016; Chen, 2021). With K-Push and the Kinvent app, you gain access to a portable, cost-effective solution that provides repeatable data and supports better clinical decision-making.

The Kinvent app guides you step-by-step through the test setup and execution. It ensures that every measurement is standardized and comparable, from one side of the body to the other, and from one session to the next. You can then use this data to customize rehabilitation programs, track progress objectively, and motivate your patients with tangible results.

No more guesswork. With the right sensors, assessing shoulder strength becomes simple, precise, and actionable.
