About this study

Official title: The Effects of a Proprioception-enhancing Assistive Orthosis on Balance and Joint Sense in Geriatric Patients

This study investigates the effects of a proprioception-enhancing assistive orthosis on balance and joint sense in geriatric patients with age-related diseases. The study uses wearable devices that deliver vibration stimuli to improve proprioceptive feedback. A total of 20 participants will be enrolled in a 24-month, IRB-approved trial at Seoul National University Hospital. The study assesses functional balance and joint position sense before and after using the device.

Being tested
proprioception-enhancing assistive orthosis

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • proprioception-enhancing assistive orthosisDevice

    A wearable device that provides mechanical vibration to the tendons around the knee and ankle to enhance proprioceptive feedback. Vibration intensity and timing are controlled automatically based on body tilt measured by an IMU sensor. The device is applied during balance and joint sense assessments conducted across three visits.

Study groups in NCT07017504
Study groupRoleWhat they receive
Proprioception-Enhancing OrthosisExperimentalGeriatric patients with age-related diseases will undergo three assessment phases: (1) without the orthosis, (2) with the orthosis worn but vibration inactive, and (3) with the orthosis worn and vibration active.
Receives: Device: proprioception-enhancing assistive orthosis

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Postural Sway

    This measures the amount of body sway during quiet standing (static) or controlled leaning in various directions (dynamic). Parameters such as center of pressure (COP) displacement, velocity, and area are recorded to assess balance stability.

    Assessments will be conducted under the following three conditions:

    1. without the orthosis,
    2. with the orthosis worn but vibration inactive, and
    3. with the orthosis worn and vibration active.

    Measured: up to 2 weeks

Secondary outcomes (5)
  1. Berg Balance Scale

    The Berg Balance Scale (BBS) is a 14-item objective measure used to assess static balance and fall risk in adults. Each item is scored on a scale from 0 to 4, with 0 indicating the lowest level of function and 4 indicating the highest level. The total score ranges from 0 to 56, with higher scores indicating better balance performance.

    Assessments will be conducted under the following three conditions:

    1. without the orthosis,
    2. with the orthosis worn but vibration inactive, and
    3. with the orthosis worn and vibration active.

    Measured: up to 2 weeks

  2. Romberg Test

    The Romberg Test is a neurological test used to assess balance and proprioceptive control. Participants are asked to stand with their feet together, arms at their sides, and eyes closed, while the examiner observes for excessive sway or loss of balance. The duration for which the participant can maintain the position without stepping or falling is recorded, up to a maximum of 60 seconds. Longer durations indicate better balance.

    Assessments will be conducted under the following three conditions:

    1. without the orthosis,
    2. with the orthosis worn but vibration inactive, and
    3. with the orthosis worn and vibration active.

    Measured: up to 2 weeks

  3. Passive Joint Position Reproduction Test (Passive JPR)

    Assesses proprioceptive accuracy by passively moving a joint (e.g., the knee) to a target angle, then asking the participant to indicate when the position is reached again. The difference between target and reproduced angles reflects proprioceptive acuity.

    Assessments will be conducted under the following three conditions:

    1. without the orthosis,
    2. with the orthosis worn but vibration inactive, and
    3. with the orthosis worn and vibration active.

    Measured: up to 4 weeks

  4. Active Joint Position Reproduction Test (Active JPR)

    Participants actively move their joint to a memorized target angle without visual or auditory cues. The accuracy of the reproduced angle is used to evaluate active proprioceptive control.

    Assessments will be conducted under the following three conditions:

    1. without the orthosis,
    2. with the orthosis worn but vibration inactive, and
    3. with the orthosis worn and vibration active.

    Measured: up to 4 weeks

  5. Threshold to Detection of Passive Motion (TTDPM)

    Measures the smallest joint movement that a participant can detect while the joint is passively moved at a very slow, constant speed. This tests the sensitivity of proprioceptive input.

    Assessments will be conducted under the following three conditions:

    1. without the orthosis,
    2. with the orthosis worn but vibration inactive, and
    3. with the orthosis worn and vibration active.

    Measured: up to 4 weeks

Questions about this trial

What is this clinical trial studying?

A study testing proprioception-enhancing assistive orthosis in people with Balance and Fall Prevention, run by Seoul National University Hospital at 1 site in South Korea.

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 5 inclusion and 14 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: opening soon, as of the sponsor's last update on 12 Jun 2025. 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 South Korea. 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 JungHyun Kim, prof (82+1088632341, kiking0@naver.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Postural Sway (time frame: up to 2 weeks). 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 12 Jun 2025.
