Initial clinical evaluation of a wheelchair ergometer for diagnostic exercise testing : a technical note

The purpose of this initial study was to evaluate a new wheelchair ergometer (WCE) and exercise test protocol for the detection of coronary artery disease in men with lower limb disabilities. Forty-nine patients (63 +/- 9 yr) completed WCE tests without complications. Peak heart rate was 84 +/- 15%...

description The purpose of this initial study was to evaluate a new wheelchair ergometer (WCE) and exercise test protocol for the detection of coronary artery disease in men with lower limb disabilities. Forty-nine patients (63 +/- 9 yr) completed WCE tests without complications. Peak heart rate was 84 +/- 15% (mean +/- SD) of age-predicted maximum and peak double product was 223 +/- 62 x 10(2). The specified target heart rate (> or = 80% age-predicted maximal) or a positive result was achieved in 76% of tests. Fourteen tests were rated positive, 21 as negative and 14 as nondiagnostic for exercise-induced ischemia. In 18 patients who underwent coronary angiography, the predictive value was 100% (10/10) for a positive, and 50% (2/4) for a negative WCE test result. These results suggest that WCE is a viable initial diagnostic option for some persons who cannot adequately perform treadmill or cycle ergometry exercise.
