Materials: (1) 10.2-cm step.
- Patient assumes a one-arm push-up position with his back flat, his feet and shoulders apart, and his weight-bearing upper extremity positioned perpendicular to the floor.
- The patient places his/her non–weight-bearing hand on the posterior aspect of the low back.
- The patient uses the weight-bearing arm to hop onto the step and lands on the rubber portion of the step with the entire hand.
- The patient then uses the weight-bearing arm to hop off of the step and return his hand to the start position next to the step.
- This is repeated 5 times as quickly as possible.
- An acceptable test is defined as a test in which the patient fully hopped onto the rubber portion of the step, did not use the other hand, did not touch down with a knee, and kept his back flat and his feet in the same position.
On average, the non-dominant upper extremity performance times were on average only 4.4% slower than dominant- upper-extremity performance times, however this difference was not statistically significant.
