Exercise, especially moderate-to-high-intensity impact exercise, has been recommended as an effective, low-cost non-pharmacological strategy for bone strength improvement; however, evidence on fracture risk is limited. In addition, maintaining regular training is currently a problem. Therefore, this study aims to conduct a randomised controlled trial of moderate-to-high-intensity tele-exercise intervention using a tele-rehabilitation app and quantify its effects on vertical fracture and fall prevention in women at high risk of osteoporotic fractures.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and analysis<\/jats:title>\n                    <jats:p>In this multicentre, randomised controlled trial, 794 women at high risk of osteoporotic fractures will be recruited and randomised into either the tele-exercise rehabilitation or control group. Participants in the control group will receive routine remote rehabilitation, while those in the intervention group will be provided with a 6-month tele-exercise rehabilitation. The primary outcomes are the percentage of participants with one or more new vertebral fractures and incidence of falls. Intention-to-treat, full analysis set and per-protocol approaches will be used for outcome analyses.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Ethics and dissemination<\/jats:title>\n                    <jats:p>The study was approved by the biomedical research ethics committee of the West China Hospital of Sichuan University (2021-579).
