Many individuals with spinal cord injury (SCI) rely on wheelchairs as their primary mode of locomotion leading to reduced weight-bearing on the lower extremities, which contributes to severe bone loss and increased risk of fragility fractures. Engaging in a walking program may reverse this vicious cycle, as this promotes lower extremity weight-bearing and mobility, which may reduce bone loss and fragility fracture risk. However, fragility fracture risk associated with the use of wearable robotic exoskeletons (WREs) in individuals with SCI needs consideration. A 35-year-old man with chronic complete sensorimotor SCI (neurological level = T6) and low initial bone mineral density enrolled in a 6- to 8-week WRE-assisted walking program after successfully completing an initial clinical screening process and two familiarization sessions with the WRE. However, after the first training session with the WRE, he developed bilateral localized ankle edema. Training was suspended, and a CT-scan revealed bilateral calcaneal fractures, which healed with conservative treatment over a 12-week period. Opportunities for improving clinical screening and WRE design are explored. The relevance of developing clinical practice guidelines for safe initiation and progression of intensity during WRE-assisted walking programs is highlighted. This case of bilateral calcaneal fractures illustrates that aiming for "zero risk" during WRE-assisted walking programs may not be realistic. Although WREs are a relatively new technology, current evidence confirms their potential to greatly improve health and quality of life in individuals with chronic SCI. Hence, ensuring their safe use remains a key priority.

在患有慢性脊髓损伤的轮椅使用者中,通过可穿戴的机械外骨骼在地面上行走后,偶然发生双侧跟骨骨折。

许多脊髓损伤(SCI)的人以轮椅为主要运动方式,导致下肢负重减少,这导致严重的骨质流失和脆性骨折的风险增加。进行步行训练可能会扭转这种恶性循环,因为这会促进下肢的负重和活动能力,从而减少骨质流失和脆性骨折的风险。但是,在患有SCI的患者中,与可穿戴式机器人外骨骼(WRE)的使用相关的脆性骨折风险需要考虑。一名35岁,慢性完全感觉运动SCI(神经病学水平= T6),初始骨矿物质密度低的男人,在成功完成了初步的临床筛查过程和两次熟悉培训后,参加了6至8周的WRE辅助步行计划与WRE。但是,在接受WRE的第一次培训之后,他患上了双侧局部性踝关节水肿。暂停训练,CT扫描显示双侧跟骨骨折,经保守治疗在12周内-愈。探索了改善临床筛查和WRE设计的机会。在WRE辅助步行计划中,安全起步和强度发展的临床实践指南制定的相关性得到强调。这种双侧跟骨骨折的病例说明,在WRE辅助步行计划中瞄准“零风险”可能是不现实的。尽管WRE是一项相对较新的技术,但目前的证据证实了WRE可以极大地改善慢性SCI患者的健康和生活质量。因此,确保安全使用仍然是关键优先事项。在接受WRE的首次培训后,他患上了双侧局部性踝关节水肿。暂停训练,CT扫描显示双侧跟骨骨折,经保守治疗在12周内-愈。探索了改善临床筛查和WRE设计的机会。在WRE辅助步行计划中,安全起步和强度发展的临床实践指南制定的相关性得到强调。这种双侧跟骨骨折的病例说明,在WRE辅助步行计划中瞄准“零风险”可能是不现实的。尽管WRE是一项相对较新的技术,但目前的证据证实了WRE可以极大地改善慢性SCI患者的健康和生活质量。因此,确保安全使用仍然是关键优先事项。在接受WRE的第一次培训后,他患上了双侧局部性踝关节水肿。暂停训练,CT扫描显示双侧跟骨骨折,经保守治疗在12周内-愈。探索了改善临床筛查和WRE设计的机会。在WRE辅助步行计划中,安全起步和强度发展的临床实践指南制定的相关性得到强调。这种双侧跟骨骨折的病例说明,在WRE辅助步行计划中瞄准“零风险”可能是不现实的。尽管WRE是一种相对较新的技术,但目前的证据证实了WRE可以极大地改善慢性SCI患者的健康和生活质量。因此,确保安全使用仍然是关键优先事项。
