Locomotion Strategies of Low Back Pain Patients

Completed

• Conditions: Chronic Low-back Pain; Walking
• Interventions: Other: Quantified analysis of walking during a task of passage through a horizontal opening

• Registration Number: NCT05337995
• Lead Sponsor: University of Rennes 2

Brief Summary

The biomechanical parameters studied in non-specific chronic low back pain patients in a locomotion task have so far focused on straight line walking. Although locomotion is primarily an automated action composed of repetitive patterns allowing movement from one place to another, walkers must respond to the environmental demands.These modifications show a flexible and adaptive approach to the constraints of the environment. In this study, we are particularly interested in a task of passage through a horizontal opening, similar to a doorway, which is a standardized task that has shown its interest in the study of perceptual-motor co-ordinations. In particular, it allows to consider anthropometric and functional abilities of individuals, reflecting their action capacities.

Arm && Interventions

Group	Intervention	Description
Control group	Quantified analysis of walking during a task of passage through a horizontal opening	Participant with no current or past chronic pain
Non-Specific Low Back Pain patients	Quantified analysis of walking during a task of passage through a horizontal opening	Participants must have pain located between the thoracolumbar hinge and the lower gluteal fold, with or without pain in either leg, present for more than 12 weeks, on a daily or almost daily basis (at least 4 days out of 7).

Primary Outcome Measures

Name	Time	Method
Critical threshold	Clinical assessment at base line	Defined as the width of opening making the transition between openings that it is possible or not to cross while walking without modification of the movement. We will then identify the trials, i.e. the door widths, where the participants have turned their shoulders. To do this, we will compare the shoulder angle observed during the doorway crossing with the average angle observed in the control conditions, corresponding to a straight line walk without any opening to cross.

Secondary Outcome Measures

Name	Time	Method
Phase shift between shoulder and pelvic angles in the transverse plane	Clinical assessment at base line	Analysis of the difference between the scapular and pelvic angles in the transverse plane during aperture crossing
Walking speed	Clinical assessment at base line	Analysis of the walking speed before the obstacle compared to the walking speed in the nominal walking condition (without obstacle on the path)
Stability of the trunk	Clinical assessment at base line	Analysis of the amplitude of the medio-lateral oscillation movements in the frontal plane during the task
Step length	Clinical assessment at base line	Analysis of the step length before the obstacle compared to the step length in the nominal walking condition (with no obstacle in the path)
