Control for Reliability

The trunk extensor test can be very realiable. The time between test administraion may effect the results slightly. Changes in the test takers body may also alter the results of the test. Students could alter the accuracy of the test results by not focusing on the chip placed infront of them and maintaing a neutral spine. To control the realiability the same equipment was used during both tests. The same directions were also recalled for both testing trials.
