Strength Isometric Test: Neck ExtensionSep 06, 2023
Here's how you can test neck extension isometric strength using Measurz Muscle Meter:
Measurz Muscle Meter: This is a device used to measure force or muscle strength. It typically consists of a handle and a sensor that quantifies the force applied.
Adjustable chair or bench: A stable surface that allows the individual being tested to sit comfortably with their back straight and feet flat on the ground.
Positioning the Individual:
- Ask the individual to sit on the adjustable chair or bench with their back straight and feet flat on the ground.
- Ensure that the individual is seated in a stable position, with their hips and back against the chair's backrest.
Orientation of the Muscle Meter:
- Adjust the Measurz Muscle Meter so that the sensor (the part that measures force) is oriented vertically. It should be aligned with the individual's forehead.
Stabilizing the Muscle Meter:
- The tester (or examiner) should hold the muscle meter against the individual's forehead with a firm but comfortable grip, ensuring that the sensor remains perpendicular to the forehead.
Performing the Test:
- Instruct the individual to perform a maximal neck extension contraction by pushing their forehead against the dynamometer with as much force as they can while keeping their neck in a fixed, straight position (isometrically).
- Ask the individual to hold this contraction for a few seconds, typically 3 to 5 seconds, while you record the maximum force displayed on the handheld dynamometer.
Recording the Result:
- Record the maximum force in units such as pounds (lbs) or newtons (N) generated during the neck extension contraction.
Repeat if Necessary:
- It's advisable to repeat the test 2-3 times with short rest periods between attempts to ensure consistency in the results.
Documentation and Analysis:
- Document the highest force measurement obtained during the test.
- Compare the results to normative data or previous measurements if available, and consider them in the context of the individual's specific needs or rehabilitation goals.
