Evaluating gait changes in patients with normal pressure hydrocephalus using smart insoles

Identifying Gait Changes From a Cerebrospinal Fluid Tap Test Using a Smart Insole in Idiopathic Normal Pressure Hydrocephalus

Observational Yonsei University · NCT06722768

This study is testing if a CSF tap can improve walking and balance in people with normal pressure hydrocephalus by using smart insoles to track their movements.

What this trial studies

This clinical trial aims to assess gait and balance changes in patients diagnosed with idiopathic normal pressure hydrocephalus (iNPH) before and after a cerebrospinal fluid (CSF) tap test. Participants will wear sensor-embedded smart insoles during physical function assessments, including the 10-meter walk test and Timed Up and Go test, to gather data on their gait parameters. The study will also evaluate cognitive and urinary symptoms through surveys administered before and after the CSF tap test. The goal is to determine if the CSF tap test leads to improvements in these areas.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals diagnosed with probable iNPH who exhibit gait disturbances and meet specific clinical and radiologic criteria.

Not a fit: Patients with significant cardiovascular, gastrointestinal, respiratory, or endocrine disorders, or those unable to walk independently, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into the effectiveness of the CSF tap test in improving gait and balance in iNPH patients.

How similar studies have performed: While there have been studies on gait analysis in neurological conditions, this specific approach using smart insoles in conjunction with a CSF tap test is relatively novel.

Eligibility criteria

Inclusion Criteria:

* individuals who have more than 1 symptom in the clinical triad including gradually developed gait disturbances mainly showing shuffling, magnetic, wide based gait
* individuals who assessed a standardized cranial MRI scan and those with an Evans ratio greater than 0.30 were included in the study (Microvascular lesions in the white matter were accepted only if they were mild.)

Exclusion Criteria:

* individuals with history of hemorrhage
* individuals unable to walk independently on flat ground for 10 meters
* individuals with clinically significant disorders in the cardiovascular, gastrointestinal, respiratory, or endocrine systems
* individuals considered clinically unsuitable for the trial by the trial manager or person in charge based on significant medical findings
