Background and study aims
High blood pressure (hypertension) is a leading risk factor for cardiovascular, brain, and kidney diseases. The treatment is medications and exercise. This study aimed to investigate the effect of regular dance therapy interventions on blood pressure in hypertensive patients.

Who can participate?
Outpatients aged 20 years and over with high blood pressure

What does the study involve?
Patients were randomly assigned to either an intervention group (dance) or a control group (self-selected exercise). The intervention group performed daily dance exercises using modern dance videos (10 minutes per video) uploaded to YouTube. The control group performed non-dance exercises for 10 min daily. Blood pressure and body composition were measured at baseline and after 2 months. The dance intervention for the intervention group was primarily conducted at the patients' homes, while the exercise for the control group was performed at a location of the patients' choosing.

What are the possible benefits and risks of participating?
By participating in this study, one potential benefit is the improvement of blood pressure. As for the risks, there is a possibility of injury during exercise.

Where is the study run from?
Juntendo University (Japan)

When is the study starting and how long is it expected to run for?
December 2022 to March 2026

Who is funding the study?
Juntendo University (Japan)

Study information

Study design	Non-blinded two-armed randomized trial
Primary study design	Interventional
Secondary study design	Randomised controlled trial
Study setting(s)	Hospital
Study type	Treatment
Scientific title	Dance your way to lower blood pressure: a randomized controlled trial on the efficacy of unsupervised dance exercise for hypertensive patients
Study objectives	Performing the same movements without monitoring using self-made dance videos could lower blood pressure and be useful as a non-pharmacological treatment for high blood pressure.
Ethics approval(s)	Approved 28/12/2022, Ethics Committee of Juntendo University (Bunkyo-ku Hogno 3-1-3, Tokyo, 113-8421, Japan; +81 (0)3 5802 1584; hongo-rinri@juntendo.ac.jp), ref: E22-0387
Health condition(s) or problem(s) studied	Hypertension
Intervention	A random number table was created in Excel, and the intervention and control groups were divided based on whether the number was greater than or less than 0.5. Hypertensive patients were randomly assigned to either an intervention group (dance) or a control group (self-selected exercise), with each group comprising 20 participants. The intervention group performed daily dance exercises using modern dance videos (10 minutes per video) uploaded to YouTube. The control group performed non-dance exercises for 10 min daily. The activity levels of the participants were monitored using a triaxial accelerometer. Blood pressure and body composition were measured at baseline and after 2 months.
Intervention type	Behavioural
Primary outcome measure	Blood pressure measured using HBP-9035 KENTARO™ (OMRON HEALTHCARE Co., Ltd.,Kyoto City, Kyoto Prefecture, Japan) at baseline and after 2 months
Secondary outcome measures	Body weight and muscle mass measured using multi-frequency body composition analyzer MC-780A (Tanita Corporation, Itabashi City, Tokyo Prefecture, Japan) at baseline and after 2 months
Overall study start date	28/12/2022
Completion date	31/03/2026
