Why is this study important?<\/b><\/p>\n

Previous research found those with lower limb amputations had reduced bone mineral density (BMD) at the hip (1). Lower hip BMD increases the risk of a hip fracture. Exercise interventions have been shown to improve BMD in other populations (2-4), but this has not been evaluated in a population with lower limb amputation previously. Before implementing any intervention, it may be helpful to obtain expert opinion designing an intervention prior to conducting a large clinical trial.\u00a0<\/span><\/p>\n

This blog is based on a recent publication in the BJSM, found <\/span>here<\/span><\/a> (5).<\/span><\/p>\n

How did the study go about this?<\/b><\/p>\n

To obtain a consensus amongst a group of experts, using the Delphi method can allow participants to be asynchronous, anonymous from each other during the process, and minimise excessive influence from dominant voices (the bandwagon effect) (6,7<\/span> \u00a0 \u00a0 <\/span>). This study aimed to elicit expert opinion using the Delphi process and gain a consensus to define a viable exercise intervention to minimise hip BMD loss following traumatic lower limb amputation. To do this we provided experts with evidence-based statements regarding previous exercise interventions (split into sections on frequency, intensity, time, and type of exercise) and the potential application to individuals following an amputation. We required 70% or more of the experts to agree with a statement to gain a consensus.\u00a0<\/span><\/p>\n

What did the study find?<\/b><\/p>\n

This Delphi process recruited 13 world leading experts and used three separate rounds of rating evidence-based statements regarding the exercise programme.\u00a0 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\u20133). 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\u201312 repetitions. Interventions should include weight-bearing exercises and involve high-impact (hopping, jumping) activities and be supervised initially.<\/span><\/p>\n

What are the key take-home points?<\/b><\/p>\n

This expert Delphi process achieved consensus on nine items related to exercise prescription to minimise hip BMD loss following traumatic lower limb amputation. As these findings were driven by best existing empirical evidence alongside leading expert opinion it could act as a current guide for best practice until future well-controlled experiments are completed in this population. These recommendations will be tested in a future feasibility trial to ensure this is acceptable to those with lower limb amputations, to ensure it is safe, and ensure we can recruit participants and that participants will adhere to the exercise programme. Consequently, we would plan to implement a full-scale clinical trial using this exercise programme to investigate if it can minimise bone mineral density loss after amputation and therefore, reduce lifelong fracture risk.\u00a0<\/span><\/p>\n
