Laboratory instrumentation of orthoses and prostheses can be used to objectively gain accurate information. In this study the measurement of orthosis wearing time during laboratory climate tests with normal volunteers were accomplished to determine the validity and reliability of the device for registering orthotic wearing time that was designed and fabricated in Iran. Orthosis wearing time is an important factor in orthotic treatment for spine disorders. A reliable and objective System for measuring orthosis wearing time currently is still lacking in Iran. After Developing such a device, our objective was to test the accuracy and validity of the device, Made in Iran which was designed to register spinal orthosis wearing time. The device had a force sensor mounted on a thoracolumbosacral orthosis pad to recorded orthosis wearing time. In an interval of 1 hour 5 Normal volunteers tested the device using a CASH orthosis. They donned the orthosis for a few minutes and doffed it meanwhile they recorded the time using a standard chronometer into the "Orthotic Wearing" form. After gaining the data one sample t-test was performed on all orthosis wearing-time intervals as recorded by the system and by the time tables filled by each of the 5 testers using a chronometer. The tests yielded 100 sensor trigger-events that is 50 times of orthotic wear (t=2.21, P=0.032). As indicated by the t-test analysis, the device for registering orthotic wearing time had accurately quantified the orthosis wearing-time intervals during the laboratory climate tests with normal volunteers.
