About this study
Official title: Assessment of Changes in Range of Motion and Muscle Endurance After Practicing the "Xuong Tan Lac Than" Exercise in Healthy Volunteers
The goal of this clinical trial is to learn the effects of the "Xuong tan lac than" exercise on range of motion and muscle endurance in healthy volunteers. The main questions it aims to answer are:
- Does practicing the "Xuong tan lac than" exercise improve joint range of motion (cervical spine, lumbar spine, shoulder, elbow, wrist, knee, and ankle)?
- Does the exercise improve muscle endurance around these joints?
Read more
Participants will:
- Perform the "Xuong tan lac than" exercise for 12 weeks (5 days per week, once daily).
- Be trained to perform the exercise correctly before starting the intervention.
- Undergo assessments of joint range of motion and muscle endurance at baseline and after 2, 4, 8, and 12 weeks.
Read the detailed description
This study aims to evaluate the effects of "Xuong tan lac than" exercise, a traditional exercise in Vietnamese exercise, on joint range of motion and muscle endurance in healthy volunteers.
Reduced joint mobility and decreased muscle endurance are common issues that may affect functional performance and quality of life. Traditional exercise methods are increasingly used to improve musculoskeletal function. However, scientific evidence regarding the effects of specific traditional exercises, including "Xuong tan lac than", remains limited.
This study is designed as a pre-post intervention study. Healthy volunteers will be recruited and assessed at baseline for joint range of motion and muscle endurance. Participants will then be trained to correctly perform the "Xuong tan lac than" exercise:
- Preparation: Participants stand in a semi-squat position with both hands interlocked and palms facing downward.
- Step 1 (Warm-up): Participants inhale deeply while raising both arms overhead.
- Step 2 (Movement): While maintaining inhalation, participants perform alternating lateral trunk movements. The trunk bends to the left with the left leg extended and the right leg slightly flexed, then alternates to the opposite side. Each side is repeated 2 - 6 times.
- Step 3 (Exhalation): Participants exhale fully while engaging the abdominal muscles and lowering the arms.
- Step 4 (Rest): Participants return to a normal breathing pattern and the initial position. The sequence is repeated 2 - 6 times.
The intervention consists of practicing the exercise for 12 weeks, 5 days per week, once daily. Each session follows a standardized protocol to ensure consistency among participants.
Assessments will be conducted at baseline and after 2, 4, 8, and 12 weeks of intervention. Range of motion will be measured using the Noraxon (Myomotion/MyoResearch) system, which utilizes inertial measurement unit (IMU) sensors attached to the body to provide objective and accurate assessment of joint movement. The primary outcomes include changes in joint range of motion (cervical spine, lumbar spine, shoulder, elbow, wrist, knee, and ankle) and muscle endurance around these joints.

What participants receive. In a randomised study each person is assigned to one group by chance.
"Xuong tan lac than" exerciseBehavioural
The exercise procedure includes the following steps:
- Preparation: Participants stand in a semi-squat position with both knees slightly flexed. The hands are interlocked in front of the body with the palms facing downward.
- Step 1 (Warm-up): Participants inhale deeply while slowly raising both arms overhead.
- Step 2 (Movement): While maintaining continuous inhalation to keep the airway open, participants perform alternating lateral trunk movements. This breathing technique is a key feature of the exercise, allowing sustained air intake to enhance oxygen exchange and support the regulation of internal energy (qi) according to traditional Vietnamese medicine principles. The trunk bends to one side with the corresponding leg extended and the opposite leg slightly flexed, then alternates to the other side. Each side is repeated 2-6 times in a controlled manner.
| Study group | Role | What they receive |
|---|---|---|
| Xuong tan lac than exercise | Experimental | Participants perform the "Xuong tan lac than" exercise once daily, 5 days per week, for 12 weeks following a standardized protocol Receives: Behavioral: "Xuong tan lac than" exercise |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change from baseline in joint range of motion measured by IMU (Noraxon MyoMotion)
This outcome evaluates the change from baseline in joint range of motion (ROM) of the cervical spine, lumbar spine, shoulder, wrist, knee, and ankle using the Noraxon MyoMotion IMU system. Each movement will be measured three times, and the average value will be used for analysis
Measured: Baseline and week 12
Secondary outcomes (1)
Change in baseline in nerve conduction parameters (CMAP and NCV)
Compound muscle action potential (CMAP) amplitude and nerve conduction velocity (NCV) will be assessed using standard electrophysiological techniques. These parameters reflect neuromuscular function and nerve conduction efficiency
Measured: Baseline and week 12

Questions about this trial
What is this clinical trial studying?
A study testing "Xuong tan lac than" exercise in people with Healthy and Physical Fitness, run by University of Medicine and Pharmacy at Ho Chi Minh City at 1 site in Vietnam.
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 3 inclusion and 4 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: looking for participants now, as of the sponsor's last update on 9 Apr 2026. 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 Vietnam. 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Anh Dao Thi Nguyen, MD, PhD candidate (+84 984 530 594, ntanhdao@mp.edu.vn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change from baseline in joint range of motion measured by IMU (Noraxon MyoMotion) (time frame: Baseline and week 12). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07520071, which also lists 21 linked publications.
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 9 Apr 2026.
