Materials: (1) 10.2-cm step.

Methods:

  • 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.

Reliability:

Study Population Type ICC
Falsone et al, 2002 Male collegiate wrestlers (Average age= 20.3) Test-Retest Reliability 0.81
Male collegiate football players (Average age= 20.0) 0.78

Interpretation:

Study Population Study Design Cut Point/Reference Value
Falsone et al, 2002 Male collegiate wrestlers (Average age= 20.3) Descriptive Laboratory Study Test= 4.72 seconds, Retest= 4.29 seconds
Male collegiate football players (Average age= 20.0) Test= 5.69 seconds, Retest= 5.44 seconds

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.
