Manual Muscle Test (MMT) System

Ergonomic hand-held device for objectively quantifying muscle strength * 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 patientÊs resistance * The MMT 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 * Features a wide range of customizable options for data storage preset test times and force thresholds * Size: 3.1 x 5 x 1.5 (7.87cm x 12.7cm x 3.8cm) * Range: 0-300 lbs (136.1kg) (1335 N) * Accuracy: +/- 1 % over full scale * Resolution: 0.1lbs/0.1kg/0.1N(0-999.9N) / 1N(1000N-1335N) * Battery Life: 6-8 hrs powered on 30 minutes after low battery condition * Charge Time: 80% charge => 45 minutes / Full charge => 2 hrs * Data Storage Capacity: 150 tests * Calibration Points: 31 point (Every 10lbs 0 – 300) * Preset Test Length: 0.5-10 seconds; in 0.1 second increments * Measures: Peak force time to reach peak force total test time time within selectable ranges & average force * Data storage for up to 150 tests in on-board memory * Automatic or manual storage of data * Measurement range 0-300 lbs (136.1 kg/1334 N) * Selectable test time from 1 – 10 seconds * Tone to indicate start stop and entering within a range * Microprocessor controlled * Built-in stored data browsing capability * Easy to read graphical LCD display * Automatic shutoff after 5 minutes of inactivity * Battery indicator on LCD display * Interactive menus allowing users to select device options * Battery powered: (1) rechargeable lithium-ion battery *
