Motivations and expectations for spinal cord epidural stimulation study participation: perspectives from individuals with spinal cord injury and caregivers
摘要
Qualitative, semi structured interviews.
ObjectivesSpinal cord epidural stimulation (scES) has shown promise for improving autonomic and motor function in individuals with spinal cord injury (SCI). Participation in translational studies often requires relocation, uprooting the individual and caregivers from their community. Recognizing this burden, this study aimed to explore the motivations and expectations driving the decision to participate in a scES study.
SettingKentucky Spinal Cord Injury Research Center, University of Louisville, USA.
Methods23 interviews were conducted at enrollment in a randomized trial evaluating scES efficacy. Respondents were 18 individuals with SCI (40 ± 10 years old, 12 ± 10 years since injury, 44% males, all cervical, ASIA Impairment Scale: 39% A, 39% B, 22% C) and 5 caregivers. Interviews were audio recorded, transcribed, and analyzed with a thematic approach.
ResultsFour main themes emerged: gaining independence, improving function, benevolence, and other. Participants and caregivers hoped that improved function would lead to more independence—described as “a little more freedom,” “experience the world,” and to “not rely on someone.” Any change was expressed as improving the quality of life. Many managed their expectations by recognizing the impact of individual characteristics on outcomes. Even if no improvement occurred, participation felt meaningful—motivated by benevolence and a desire to advance SCI research and help others.
ConclusionsPeople with SCI and their caregivers participate in scES research with cautious optimism to gain freedom and improve quality of life through improved function. They also aim to help others through advancing science.
