Reliability of Kinovea in Gait Assessment in Multiple Sclerosis: a Pilot Study.

Reliability of the Kinovea System in the Study of Spatiotemporal Gait Parameters in Multiple Sclerosis: a Pilot Study.

The objective of this observational study is to determine whether the Kinovea video analysis tool is valid and reliable for analyzing spatiotemporal gait parameters in multiple sclerosis, comparing the data obtained from this system with those of the gold standard, the GaitRite system. The main question to be answered is:

Is the Kinovea system valid and reliable for analyzing spatiotemporal gait parameters in multiple sclerosis?

Participants walked across the GAITRite platform four times without shoes and four times with shoes, while being recorded by two cameras simultaneously: one recorded gait from the sagittal plane and the other from the frontal plane.

Inclusion Criteria:

• Patients scheduled for evaluation by the NeuroLab-Lázaro gait laboratory (Seville).
• Patients who have signed informed consent prior to the test.
• Patients between 18 and 55 years of age, diagnosed with MS according to the 2017 McDonald criteria.
• Patients with an EDSS score of less than 6.5 points.
• Patients who are willing to participate in the study and who do not object to being recorded while performing the gait test and to the use of images for educational and research purposes.

Exclusion Criteria:

• Patients who use walking aids and/or orthoses.
• Patients with comorbidity or decompensated systemic disease within the last month.
• Patients who have any physical impediment (excessive fatigue) to performing the gait test, as documented in their medical records reviewed on the Diraya platform.
• Patients who have suffered a relapse within 30 days prior to the start of the study.
