Effects of a CBD and Natural Ingredients Cream on the Chronic Pain of Triathletes, Runners, Cyclists, and Swimmers

Spain35 participantsStarted 2025-01-18

Plain-language summary

There is a high prevalence of chronic pain in our society, which is detrimental at an individual and country level. Cannabidiol (CBD) has been proposed as a promising treatment for chronic pain, although more high-quality studies are needed in this area. On the other hand, triathlon, running, cycling, and swimming are sports modalities that have an increasing professionalism and importance, albeit not exempt from injuries. The main goal of this study is to assess the effectiveness of a topical treatment for recurrent chronic pain caused by tendinopathies with a cream containing CBD in triathletes, runners, cyclists, and swimmers. Consequently, the research question for this study is the following: Can the CBD cream be effective in treating chronic pain? The investigators hypothesize that the cream will be able to affect the pain, both in the short and the long term. The study will be interventional, with a crossover, randomized, and double-blinded design. Two groups of participants will be generated, as well as two treatment options (CBD cream, and a similar one without the CBD). The subjects will apply one of the treatments for one month, followed by a wash-out week without any cream application, and another month with the other treatment. During these weeks, different parameters will be controlled via online questionnaires. The analyzed variables will include the following: Chronic pain, acute pain, wellness, perceived exertion, quality of life, and satisfaction with the treatment. Different statistical tests will be applied to the collected data, comparing their means and correlations to infer the results.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
