Abstract

Objective

To investigate the feasibility, usability, and acceptability of the Spinal Cord Injury Program in Exercise intervention.

Design

Three-arm randomized controlled trial.

Setting

Video-based exercise sessions via an online teleexercise platform.

Participants

Thirty-six participants (N=36) with spinal cord injury (52.8% women, 47.2% men), aged 18-65 years, were randomized to movement-to-music (M2M, n=12), standard exercise training (SET, n=12), or attention control (AC, n=12).

Interventions

M2M and SET participants completed 3 weekly exercise sessions for 8 weeks, while AC participants received weekly educational articles.

Main Outcome Measures

Primary outcomes included feasibility (recruitment and retention rates), platform usability (System Usability Scale, Health IT Usability Evaluation, and qualitative interviews), and acceptability (8-item Physical Activity Enjoyment Scale and qualitative interviews). Preliminary outcomes included changes in physical activity (Leisure Time Physical Activity Questionnaire for People with Spinal Cord Injury) and quality of life (Patient-Reported Outcomes Measurement Information System short forms) at 8 weeks postintervention. Analyses included descriptive statistics, effect size estimation, and qualitative interview analysis.

Results

Follow-up retention at weeks 8, 12, and 16 was 66.7%, 41.7%, and 41.7% for M2M; 83.3%, 66.7%, and 66.7% for SET; and 83.3%, 75.0%, and 66.7% for AC, respectively. The mean ± SD of system usability scale score was 69.8±17.1. SET participants rated the intervention “good,” and M2M and AC rated it “fair.” The mean Health IT usability evaluation scale score of 3.61±0.54 indicated moderate satisfaction, with “Impact” highest and “Perceived Usefulness” lowest. Preliminary outcomes suggested small to moderate improvements in physical activity and quality of life for SET, with effect sizes (Hedge’s g) ranging from 0.13 to 0.71.

Conclusions

The interim analysis shows high feasibility and moderate usability and acceptability. Preliminary outcomes suggest potential benefits in physical activity and quality of life, particularly for SET. Future research should focus on enhancing platform usability and long-term participant engagement strategies.

一项评估脊髓损伤个体远程运动干预的随机对照试验的可行性、可用性和可接受性：运动中脊髓损伤计划（SCIPE）研究的中期分析

目的探讨脊髓损伤方案在运动干预中的可行性、可用性和可接受性。设计：三臂随机对照试验。通过在线远程锻炼平台设置视频锻炼课程。参与者36名（N=36）脊髓损伤患者（女性52.8%，男性47.2%），年龄18-65岁，随机分为音乐运动（M2M， N= 12）、标准运动训练（SET， N= 12）或注意力控制（AC， N= 12）组。干预：sm2m和SET参与者每周完成3次锻炼，持续8周，而AC参与者每周接受教育文章。主要结果测量主要结果包括可行性（招募率和保留率）、平台可用性（系统可用性量表、健康IT可用性评估和定性访谈）和可接受性（8项体育活动享受量表和定性访谈）。初步结果包括干预后8周体力活动（脊髓损伤患者休闲时间体力活动问卷）和生活质量（患者报告的结果测量信息系统简短表格）的变化。分析包括描述性统计、效应量估计和定性访谈分析。结果M2M组随访8、12、16周的保留率分别为66.7%、41.7%、41.7%；SET分别为83.3%、66.7%和66.7%；AC分别为83.3%、75.0%、66.7%。系统可用性量表得分的平均值±SD为69.8±17.1。SET参与者认为干预“好”，M2M和AC认为干预“一般”。健康信息技术可用性评价量表平均得分为3.61±0.54，为中等满意度，其中“影响”得分最高，“感知有用性”得分最低。初步结果显示，SET患者的身体活动和生活质量有小到中度的改善，效应量（Hedge’s g）在0.13到0.71之间。结论中期分析表明该方法具有较高的可行性，可用性和可接受性适中。初步结果表明在身体活动和生活质量方面有潜在的益处，特别是对于SET。未来的研究应侧重于提高平台可用性和长期参与者参与策略。
