An observational study in Spinal Cord Injuries (SCI), sponsored by Shengjing Hospital. Not yet recruiting. Open to participants aged 16 Years to 80 Years. Per ClinicalTrials.gov, last updated 2026-07-10.
Sponsored by Shengjing Hospital · Observational
The goal of this observational study is to evaluate whether increased lower extremity muscle tone can serve as an independent predictor of neurogenic detrusor overactivity (NDO) in adult patients (aged 18-80 years) with upper sacral spinal cord injury .
The main questions it aims to answer are:
Is increased lower extremity muscle tone independently associated with the presence of detrusor overactivity after adjusting for age, sex, injury level, injury type, and injury cause?
Does the predictive value of muscle tone for detrusor overactivity differ across subgroups defined by injury level, injury severity, and time since injury?
Researchers will compare patients with lower extremity hypertonia (Modified Ashworth Scale ≥ 1) to patients with normal muscle tone (Modified Ashworth Scale = 0) to see if muscle tone elevation independently predicts detrusor overactivity.
Participants will not be asked to do anything beyond their routine clinical care, as this is a retrospective study that only collects data from existing medical records, including neurological examination results, Modified Ashworth Scale scores, and urodynamic study reports.
This study looks at adults aged 18 to 80 with suprasacral Spinal Cord Injury who stayed at the Shengjing Hospital of China Medical University from January 2020 to January 2025. All participants have full medical records, including neurological exams, Modified Ashworth Scale checks, and urodynamic test results. Anyone missing key data or with assessments spaced out by more than two weeks was left out.
Diagnosis of spinal cord injury confirmed by CT or MRI imaging
Suprasacral spinal cord injury according to the International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI, 2011 revision)
Age between 18 and 80 years
Complete medical records, including detailed neurological examination, Modified Ashworth Scale assessment, and urodynamic study report
Exclusion Criteria:
Critical missing information in medical records or urodynamic reports
Interval between Modified Ashworth Scale assessment and urodynamic study exceeding 2 weeks
Patients with lower extremity hypertonia, defined as a Modified Ashworth Scale (MAS) score of 1 or higher at admission.
Patients with normal lower extremity muscle tone, defined as a Modified Ashworth Scale (MAS) score of 0 at admission.
Presence of Neurogenic Detrusor Overactivity Confirmed by Urodynamic Study
Neurogenic detrusor overactivity (NDO) is defined as the presence of involuntary detrusor contractions during the filling phase of a urodynamic study, according to International Continence Society (ICS) standards. Urodynamic studies were performed as part of routine clinical care during the hospital admission. This outcome measures the presence or absence of NDO based on the urodynamic report. The result is reported as a binary outcome (present/absent).
