Device Specifications

Activforce 2

Activforce 2 is a handheld dynamometer and inclinometer produced by ActivBody Inc. made for professionals to perform strength and range of motion testing.

Activforce 2 can measure:
・Active and Passive Range of Motion (AROM & PROM)
・Peak Force
・Average Force
・Force Over Time
・Force / Weight Ratio
・Muscular Symmetry
・Neuromuscular Deficits

The Activforce 2 companion app utilizes advanced technology to display and record real-time force and range of motion.

Internal Mechanical Testing Results

The Activforce sensor (ActivBody Inc, San Diego, California, USA) was measured for calibration over the range of 0 to 50 kg (110 LBS) using mechanical testing equipment to avoid human error in evaluation. The Activforce sensor is not able to read small forces, however, the testing apparatus device exceeded this minimum force reading, permitting low to high force testing that would serve individuals across developmental ages for sport participation up to professional athletes.

Given the results of mechanical testing below, the Activforce sensor indicates high accuracy up to approximately 100 lbs making the internal components suitable for testing throwing arm strength in various positions. Suggested possible reasons for losing tolerance after the recommended load limits could be accounted for by user operation considerations, deformation of the plastic housing, contact of the battery cover with the sides of the housing and there may be other reasons inherent to the design of the manufacture that are not assessed that may impact results.
