To elicit expert opinion and gain consensus on specific exercise intervention parameters to minimise hip bone mineral density (BMD) loss following traumatic lower limb amputation.
In three Delphi rounds, statements were presented to a panel of 13 experts from six countries. Experts were identified through publications or clinical expertise. Round 1 involved participants rating their agreement with 22 exercise prescription statements regarding BMD loss post amputation using a 5-point Likert scale. Agreement was deemed as 3-4 on the scale (agree/strongly agree). Statements of <50% agreement were excluded. Round 2 repeated remaining statements alongside round 1 feedback. Round 3 allowed reflection on round 2 responses considering group findings and the chance to change or maintain the resp onse. Round 3 statements reaching ≥70% agreement were defined as consensus.
All 13 experts completed rounds 1, 2 and 3 (100% completion). Round 1 excluded 12 statements and added 1 statement (11 statements for rounds 2-3). Round 3 reached consensus on nine statements to guide future exercise interventions. Experts agreed that exercise interventions should be performed at least 2 days per week for a minimum of 6 months, including at least three different resistance exercises at an intensity of 8-12 repetitions. Interventions should include weight-bearing and multiplanar exercises, involve high-impact activities and be supervised initially.
This expert Delphi process achieved consensus on nine items related to exercise prescription to minimise hip BMD loss following traumatic lower limb amputation. These recommendations should be tested in future interventional trials.
征求专家意见并达成共识,确定具体的运动干预参数,以最大程度地减少创伤性下肢截肢后髋部骨密度(BMD)的丢失。
在三轮 Delphi 研究中,向来自六个国家的 13 名专家小组展示了 22 条关于 BMD 丢失的运动处方陈述。通过出版物或临床专业知识来确定专家。第 1 轮让参与者使用 5 分制量表对 22 条关于截肢后 BMD 丢失的运动处方陈述的同意程度进行评分,3-4 分表示同意/强烈同意。将低于 50%的同意率的陈述排除。第 2 轮重复了其余的陈述以及第 1 轮的反馈。第 3 轮允许专家根据第 2 轮的反馈结果进行思考,并考虑改变或维持之前的回应。第 3 轮达到≥70%同意率的陈述被定义为共识。
所有 13 名专家均完成了第 1、2 和 3 轮(100%完成)。第 1 轮排除了 12 条陈述并增加了 1 条陈述(第 2-3 轮共 11 条陈述)。第 3 轮就指导未来运动干预的九条陈述达成了共识。专家们一致认为,运动干预应至少每周进行 2 天,持续至少 6 个月,包括至少三种不同的、强度为 8-12 次重复的抗阻运动。干预应包括负重和多平面运动,涉及高冲击活动,并在最初时接受监督。
本专家 Delphi 研究就创伤性下肢截肢后最大程度减少髋部 BMD 丢失的运动处方九条建议达成了共识。这些建议应在未来的干预性试验中进行检验。
