Due to physical limitations, environmental restrictions, and social deterrents, people with spinal cord injury (PwSCI) are a sedentary population who often lack motivation to exercise ( Ginis et al., 2012 ; Gorgey, 2014 ; Kehn & Kroll, 2009 ; Yıldırım & Şengel, 2004 ). PwSCI also find

One form of spinal cord injury (SCI) classification is to stratify into 2 groups: tetraplegia (TP), which involves injuries between the cervical vertebrae (C6–C8), and paraplegia, between the thoracic, lumbar, and sacral vertebrae (T1–L2). 1 , 2 This division is by the American Spinal Injury

Spinal cord injury (SCI) is a traumatic event, with strong implications for the affected individuals, 1 and is frequently associated with considerable changes in individual function and socialization. 2 In the United States, the incidence of SCI is 17,000 per year. 3 However, reliable data in

It is estimated that nearly 300,000 individuals are living with spinal cord injury (SCI) in the United States, with nearly 18,000 new injuries occurring annually. 1 Over 40% of individuals with SCI use manual wheelchairs for mobility, as well as interacting with their environment. 1 Consequently

Spinal cord injury (SCI) is defined as damage to the spinal cord which influences the patient’s abilities for standing, walking, and doing their daily activities. 1 The incidence of this injury varies from one country to another. 2 , 3 It has been shown that in the United States, the annual

The contributions of intrinsic (passive) and extrinsic (active) properties of the human trunk, in terms of the simultaneous actions about the hip and spinal joints, to the control of sagittal and coronal seated balance were examined. Able-bodied (ABD) and spinal-cord-injured (SCI) volunteers sat on a moving platform which underwent small amplitude perturbations in the anterior-posterior (AP) and medial-lateral (ML) directions while changes to trunk orientation were measured. A linear parametric model that related platform movement to trunk angle was fit to the experimental data by identifying model parameters in the time domain. The results showed that spinal cord injury leads to a systematic reduction in the extrinsic characteristics, while most of the intrinsic characteristics were rarely affected. In both SCI and ABD individuals, passive characteristics alone were not enough to maintain seated balance. Passive stiffness in the ML direction was almost 3 times that in the AP direction, making more extrinsic mechanisms necessary for balance in the latter direction. Proportional and derivative terms of the extrinsic model made the largest contribution to the overall output from the active system, implying that a simple proportional plus derivative (PD) controller structure will suffice for restoring seated balance after spinal cord injury.

Up to 75% of men with spinal cord injury (SCI) suffer from erectile dysfunction of neurologic origin and ingest sildenafil citrate regularly. 16 Thus, one can presume that also a substantial proportion of wheelchair athletes use sildenafil citrate. Therefore, more

The rationale for the intervention is flawed (i.e., to decrease sedentary behavior in people with spinal cord injury). A person with SCI, by definition, will always be sedentary. — Anonymous journal reviewer People living with spinal cord injury (SCI) are at the lowest end of the physical
