BACKGROUND: There is some evidence that upper-body training modalities can improve not only aerobic capacity but also seated balance in people with spinal cord injury (SCI), even in those classified with motor-complete paralysis above T6. Here, we evaluated the effect of arm crank ergometry (ACE) "spin" training on trunk muscle recruitment and its effects on seated balance and aerobic capacity.
METHODS: Eight individuals with high-level complete and 6 with either a low-level complete or a motor-incomplete SCI participated in this study. Participants completed 5 weeks of a group ACE "spin" training protocol which featured modulations in cadence and resistance as well as back-supported and unsupported bouts. Surface electromyography was used to confirm trunk muscle recruitment during unsupported ACE. Changes in aerobic capacity (peak oxygen consumption) and seated balance control (center of pressure parameters) were assessed at pre- and post-intervention.
RESULTS: Unsupported ACE was effective for eliciting trunk muscle activity (P < .05). Following training, peak oxygen consumption significantly improved by an average of 16% (P = .005). Static sitting balance significantly improved from pre- to post-intervention, but only when tested with eyes closed as measured by a reduction in area (P = .047) and velocity of center of pressure (P = .013). No significant changes were observed in static sitting balance with eyes open or in dynamic sitting balance.
CONCLUSION: Group ACE "spin" classes may benefit not only aerobic fitness but also static seated balance control in people with SCI.
