User Guide | Activforce2

Activforce 2 includes a handheld dynamometer and inclinometer that provide accurate force and angle measurement along with an easy-to-use companion application that tracks and records patient progress. The comprehensive Activforce 2 platform provides real-time strength and range of motion measurements and tracks patient progress along the rehabilitation continuum.

The Activforce 2 package includes the following components

Activforce 2 dynamometer
Rounded pad
Arched pad
Hand and leg straps
Mobilization belt
Belt loop plate
Custom carrying case

The rounded pad is the default accessory for measuring strength and range of motion on most body parts, while the arched pad is used to test angular body parts such as the elbow. The mobilization belt aids in pull measurements by helping therapists apply traction to the spine or the joints to stabilize movement during certain protocols. Hand and leg straps are provided to securely hold the Activforce 2 dynamometer in place during measurement.

USAGE, SAFETY, MAINTENANCE AND TROUBLESHOOTING

Usage

The Activforce 2 dynamometer is designed for measuring compressive forces up to 90 kg or 200 lbs. by applying pressure to the dynamometer’s exterior surfaces, when placed between two body parts, such as your palms, or a body part and object, such as your palm and a desktop. Pressing on or near the belt will result in an inaccurate force measurement and may cause physical injury. Make sure to follow the instructions and guidelines, as provided in the Activforce 2 mobile companion app and/or the FAQ's.

Safety

The Activforce 2 dynamometer is certified compliant with all required safety standards and regulations, including electro-magnetic compatibility and hazardous materials, for all territories it is distributed in.

Flammability

The Activforce 2 dynamometer is not waterproof and should not be immersed in or sprayed with water or other liquids. Like many consumer electronic devices, it is flammable and should be kept from exposure to flame or other excessive heat sources. The dynamometer performance can be also affected by extreme temperature or humidity.

Cleaning

The Activforce 2 dynamometer's external surfaces, including rounded pad and arched soft pad silicon surface can be hand wiped at room termperature with a soft cloth saturated with a cleaning agent such as a 70% solution of isopropyl alcohol and water. The cleaning agent should be allowed to evaporate completely before using the dynamometer. Other antibacterial cleaning agents can be used, such as:

non-alcohol based hand wipes
alcohol based hand gels consisting of 70% ethanol

These agents may leave trace residue which ca be wiped away with a soft, dry, clean tissue. A bleach solution of hypochlorite at 10,000ppm (or 1% solution) can also be used to clean the dynamometer surfaces, re-attachble pads and silicon covers.

Reset

Your Activforce 2 dynamometer undergoes a normal reset cycle each time you turn it on and on. In rare troubleshooting situations, a hard reset may be required. To do this, simply take the battery out of its compartment and insert it back in, following the battery replacement instructions in this User Manual.

Service and Troubleshooting

Other than the Battery Replacement and Reset (as described in this User Manual), the Activforce 2 dynamometer is designed for service by authorized personnel only. For further information, please contact support@activbody.com.
