Post-Stroke Osteopathy
Study Details
Study Description
Brief Summary
The sudden biomechanical inactivation, direct neuro-humoral effects and sustained systemic stress reaction, which commonly occur after stroke or TIA, all may be of relevance in triggering alterations in bone metabolism and remodelling of bone microstructure.
The objectives of this observational pilot study are to characterize falls and fractures and their circumstances (sex and age specific incidence, time course, risk conditions, localization) in ischemic stroke patients, study changes in the bone microstructure after ischemic stroke supported by high-resolution peripheral quantitative Computer Tomography, unravel a molecular mechanisms underlying the increased fracture risk (focus on Wnt-signaling and ß-adrenergic projection), establish risk factors to estimate the risk of falls based on information from gait analysis as well as construct deep learning algorithms to identify bone microstructure parameters for predicting fractures.

Outcome Measures
Primary Outcome Measures
- Number of patients with and without fractures [12 months]
Other Outcome Measures
- Changes in imaging bone structure between the baseline and follow-up in all extremities as measured by quantitative CT imaging [12 months]
- Number and circumstances (housing situation, concomitant medication, level of immobility,...) of falls between baseline and one-year follow-up [12 months]
Due to the observational nature of the study, these outcome parameters will be published with descriptive statistics
- Change in blood bone biomarkers (as mentioned before) between baseline and follow-up [12 months]
CTX1 und CTX 2, Osteocalcin, TRAP5b, Bone Alkaline Phosphatase, Sclerostin, Periostin, RANKL-OPG-Ratio
- Circumstances (housing situation, concomitant medication, level of immobility,...) of fractures during the twelve-month follow up [12 months]
