Strength was tested in all subjects via an isometric handgrip dynamometer (tested in the dominant hand with three maximal efforts) and isometric leg extension transducer (used on the right leg for three maximal efforts). Here, the controls initiated their own right leg contractions, while the paraplegics were subjected to electrically stimulated contractions. In addition, hand and leg contractions were maintained at 40% intensity for 10 minutes after the initial maximal fatiguing effort. With the duration of every fatiguing isometric contraction measured, heart rates were recorded at rest and approximately every 15 seconds through electrocardiographic techniques. Blood pressure was recorded through traditional manual auscultation at rest, about every 20 seconds during the contraction and at 30 and 60 seconds post-contraction. Finally, statistics were calculated using analysis of variance and t-test analyses, with a level of significance of P < 0.05.
