About this study

Official title: Efficacy of Foot Baths With and Without Ginger Powder Additive on the Subjective Feeling of Warmth and on Body Core Temperature of Adolescents With Anorexia Nervosa - a Randomized, Controlled Pilot Study

A study to explore whether warm water footbaths with added ginger powder can improve thermoregulatory processes in adolescent anorexia nervosa patients and provide them with an increase in subjective feeling of warmth. The participants will receive a warm footbath four times a week for six weeks with a physiological and psychological testing point once before the beginning of the six-week footbath period and once after.

Read the detailed description

This is a two-arm randomized controlled trial to evaluate the efficacy of warm water footbaths with added ginger powder (experimental) compared to warm water only footbaths (control) in adolescent anorexia nervosa patients. Participants will receive footbaths 4 times per week before bed-time over a period of six weeks.The main focus is on subjective increase in overall body warmth. Moreover, core body temperature, skin temperature at the extremities and several psychological as well as physiological scores and parameters are assessed before and after the six-week intervention. A follow-up is planned at six months post intervention, where core body temperature, physiological and psychological parameters are once more tested.

Questions about this trial

What is this clinical trial studying?

A study testing ginger powder footbath and warm water only footbath in people with Adolescent Anorexia Nervosa, run by ARCIM Institute Academic Research in Complementary and Integrative Medicine at 1 site in Germany.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 21 Jul 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Chnge in Subjective feeling of overall warmth (time frame: Baseline (pre intervention), 6 weeks after baseline (post intervention)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Jul 2020.
