Spinal Balance With Wearables - Case-control

January 28, 2021 updated by: University College, London

Measuring Dynamic Spinal Balance With Wearable Activity Trackers. A Case Control Study.

Observational case-control study to see if the Margin of Stability and Dynamic Postural Stability (measured using a motion capture gait laboratory and wearable device, respectively) are different in children with Adolescent Idiopathic Scoliosis and matched controls. Participants will walk across level ground and on a treadmill once for data collection and no follow-up is required.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The goal of this observational case-control study is to validate the Margin of Stability (MoS) and Dynamic Postural Stability (DPS) measures using a motion capture gait laboratory and wearable device in patients with Adolescent Idiopathic Scoliosis (AIS).

These measures will provide a consultant with objective data about a patient's movement and balance that the consultant and other healthcare professionals can use to infer about their spinal deformity progression or improvement. This research is an early step for working towards providing a distance medicine, non-invasive outcome measure that can be used alongside or in the absence of current clinical measures and radiography. Use of this data could reduce the frequency with which radiographs are required and so reduce the impact of radiation exposure. This wearable device could complement and improve upon existing outcome measures in the treatment of spinal deformity, reduce the need for radiographs and ameliorate the need for distance patient monitoring methods. A motion capture gait laboratory will be used as the gold-standard comparison.

A pilot study has been carried out on healthy participants with a simulated spinal deformity in a kinematic gait laboratory and using the wearable device, which showed altered balance in the simulated scoliosis group compared to controls.

The aim of this project is to:

  1. To see if there's a difference in MoS and DPS between children with AIS and controls,
  2. To see if a difference can be detected using motion capture gait analysis and a wearable device,
  3. To see how similar results from the wearable device are to the motion capture gait laboratory,
  4. To test the ability of the wearable device to measure a scalable difference between radiographic curve magnitude in patients with AIS.

Participants will attend one data collection appointment where they will walk across level ground and on a treadmill. No follow-up is required.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

10 years to 18 years (ADULT, CHILD)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

Female

Sampling Method

Non-Probability Sample

Study Population

Patient records will be accessed by a member of the clinical care team with legitimate access to patient records and who is independent to the research team to identify eligible patients as 'Case' participants. These patients and their parents will be approached with a letter asking them to contact the researcher if they are interested in participating. Additionally, recruitment posters will be displayed in the RNOH outpatient and RNOH orthotics departments.

For 'Control' participants, with permission from the participating schools and colleges, a letter will be sent to parents of children aged 10-18 at local schools and colleges requesting they volunteer for this study.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
