Isokinetic testing of arm elevation in the scapular plane offers several advantages over the frontal plane. The purpose of this investigation was to determine the intraexaminer reproducibility of scapular plane(30
$^\circ$
anterior to frontal plane) elevation peak torques using a Cybex 340 isokinetic dynamometer. Twelve female and three male (N=15) noninjured college students were tested on three separate occasions over a six week interval. Dominant shoulder scapular plane elevation was measured with participants seated utilizing a modified abduction/adduction protocol. Testing consisted of four gradient sub-maximum to maximum warm-ups followed by five maximum repetitions at 60

/sec, 180

/sec. Intraclass correlation coefficients (ICCs) indicated that scapular plane elevation peak torques may be measured using these techniques with good reproducibility at 60

/sec (0.870) and 180
$^\circ$
/sec (0.827), and fair reproducibility at 300
$^\circ$
/sec (0.708). Results suggest that scapular plane arm elevation isokinetic testing should be conducted at slower angular-velocities to obtain more reproducible measurements.
