Use of EMG to Assess Clinical Hypertonia
A handheld surface electromyography device will be tested by clinicians on children with limb hypertonia, and inter-rater reliability will be assessed with and without the device.
Device: portable surface electromyography
|Study Design:||Observational Model: Defined Population
Primary Purpose: Screening
Time Perspective: Cross-Sectional
|Official Title:||Initial Assessment of the Use of Surface Electromyography as a Tool for Clinical Evaluation of Hypertonia in Children|
|Study Start Date:||January 2007|
|Study Completion Date:||March 2007|
Qualitative surface EMG measurement during passive movement will increase the inter-rater reliability of clinicians for diagnosis of spasticity and dystonia in children with hypertonia.
- Develop a handheld surface EMG device with auditory output that can be used similarly to a stethoscope to listen non-invasively to the activity of muscles.
- Provide clinicians at 5 different institutions with a device to test for 2 months in their own clinics.
- Bring all 5 clinicians to Stanford University for a single-day exercise in which each clinician will examine 10 children with hypertonia. Each clinician will rate the children without using the device, and then again with the device. Intra-class correlations and kappa statistics will be used to assess whether the use of the device leads to improved inter-rater reliability.
