Validation Study of Posturology Platforms for Evaluating Postural Control of Hemiparetic and Neuro-muscular Patients (KPLATES)

May 30, 2025 updated by: Assistance Publique - Hôpitaux de Paris

Validation Study of Posturology Platforms and Exploratory Study for Evaluating Postural Control of Hemiparetic and Neuro-muscular Patients

The instrumental evaluation of standing postural control by posturographic analysis supplements the clinical evaluation and, as such, is recommended by the French National Authority for Health (HAS 2007). The quantitative data obtained after a standardized postural examination appear relevant for the longitudinal follow-up of neuromuscular patients and hemiparetic patients. Neuro muscular (NM) diseases are progressive, these instrumental evaluations can highlight a deterioration or stabilization of postural control possibly not observable with the scores on clinical scales.

The K-Force Plates, recently developed appear to be an interesting alternative to the stabilometry platforms currently used. Static and dynamic conditions in upright position are tested. Moreover, posturologic, kinematics data and clinical scores are correlated to increase understanding of strategies during postural control tasks in patients with stroke and in patients with NM disorders.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

To date, no clinical validation study of these K-Force Plates force platforms has been proposed. The investigator hypothesize that the data obtained by the Plates are comparable to the measurements made by the reference tool, the AMTI platforms during a static and dynamic posturographic examination in MNM, hemiparetic and healthy subjects. The strategies of the patients (stroke and NM) during the dynamic task are also explored with kinematic analysis in correlation with data from force platforms and clinical scores.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

Study Population

Single stroke hemiparetic patient, or patient with neuro-muscular disease, or healthy subject free of neurological disorder and other disease.

Description

"Eligible couples must present all the following criteria :

  • Signing of the informed consent form
  • Men and women aged from 18
  • Single stroke hemiparetic patient, or patient with neuro-muscular disease, or healthy subject free of neurological disorder and other disease
  • Patient able to stand alone at least 30 seconds without technical assistance (multiple repetitions)

To be included, patient should not present any of the following criteria :

  • Bilateral brain injury, cerebellar syndrome
  • Other disease or defect that may interfere with the study such as visual, vestibular or other related uncontrolled medical condition

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.
Outcome Measure
Measure Description
Time Frame
Evaluate the concurrent validity of K-Force Plates (K-Invent) force platforms in comparison with reference platforms (AMTI) for posturological examination in static and dynamic conditions of MNM subjects (CMT), hemiparetic subjects and healthy subjects.
Time Frame: Day 0
Intraclass correlation coefficient (ICC) of the mean velocity of the pressure center (CP) with the both platforms during the posturological examination. The average of 3 tests carried out will be taken
Day 0

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Evaluate convergent validity with the reference scale for the assessment of equilibrium disorders
Time Frame: Day 0
Berg's equilibrium rating scale (0-56) ( score at 0: worse outcome)
Day 0
Compare the posturology and kinematics between stroke and healthy subjects and between NM and healthy subjects
Time Frame: Day 0
Explore the relations between the posturology, kinematics and clinical parameters in stroke population and in NM population.
