Wavelet Analysis of Electromyography (EMG) in Cerebral Palsy
NCT00504049 · View on ClinicalTrials.gov ↗
Study Summary
Several methods exist to evaluate motor function in the child with cerebral palsy and are used to assess the outcome of a clinical intervention. However, these scales are not directed towards measuring the changes in muscle activity patterns that can result from the intervention. For example, there are classification scales aimed at measuring motor function and functional abilities, and indices of gait function. These scores, while providing a way to quantify function and mechanics, do not directly measure muscle activation characteristics. Therefore, these tests may be insensitive to how the intervention has directly affected muscle function, which is usually the focus of the intervention (i.e. botulinum toxin, functional electrical stimulation, dorsal rhizotomy). Muscle biopsies and motor evoked potentials can provide information about the muscle activation characteristics, however, they are invasive and there are concerns about using these techniques on the pediatric population and/or the practicality of clinical implementation, especially since they do not provide insight into how the muscle behaves during a functional task. One method that can be used to provide insight into muscle activity in a non-invasive and clinically meaningful manner is the use of surface electromyography (sEMG). Surface EMG is typically a routine part of clinical assessment and the evaluation of motor impairment in CP. However, the analysis of the data has been limited in most cases to examination of signal amplitude or differences in muscle onset and offset timing. The long-term goal of this research is to develop an analysis method for sEMG that can be used during functional tasks for treatment planning, diagnostic, assessment purposes in CP. This is to be accomplished through the use of the continuous wavelet transform (CWT). By developing an assessment method based on muscle activity, it is believed that a clinically viable measurement tool can be devised that will provide a level

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00504049
The ClinicalTrials.gov registry entry for NCT00504049 describes a study currently listed as completed. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 32 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Shriners Hospitals for Children, which has 3 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Cerebral Palsy appearing as the primary indexed condition, and to 0 interventions. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00504049 reports 1 study location spanning 1 distinct geographic area — top geographies include Pennsylvania. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above.
