The test is performed with the clinician applying force to the limb of a patient.
The objective of the test is for the clinician to overcome or “break” the patient’s resistance. The HHD records the peak force and the time required to achieve the “break” providing reliable, accurate and stable muscle strength readings that conform to most manual muscle testing protocols.
The HHD also features intuitive interactive menus, enabling a wide range of configurable options including data storage, preset test durations and force thresholds.
Whilst powerful and versatile, the HHD is still small enough to fit comfortably in the palm of the hand.
Its practical design allows for both the patient and clinician comfort while easily conforming to manual muscle testing protocols.
The HHD uses a rechargeable lithium-ion battery with a battery life of 6 hrs when powered on and has a range of 0-135kg (300lb/1335N) with an accuracy of ± 1 % over full scale.
It comes with three easy to change molded plastic stirrups with pads, power charger, sturdy carry case and a Calibration Certificate.
Its microprocessor is controlled with an easy-to-read graphical LCD display with data storage for up to 150 tests in on-board memory.
