Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The aim of this project is to locate and compare areas of brain activation associated with spontaneous (Study 1) and training-induced (Study 2) recovery of touch sensation following stroke, using serial functional magnetic resonance imaging (fMRI).
Intervention involves stimulus specific training of touch sensation and includes graded presentation of stimuli, active exploration, feedback and calibration of sensations. Training is conducted for 15 x 45 minute sessions over a 6 week interval.
Intervention code [1] 573 0
Rehabilitation
Comparator / control treatment
The control condition involves exposure to similar touch stimuli over the same number of sessions but does not include training principles.
Control group
Placebo

Outcomes
Primary outcome [1] 1006 0
The primary outcome is change in intensity, particularly in ipsilesional primary somatosensory cortex and bilateral secondary somatosensory cortex.
Timepoint [1] 1006 0
Assessed between 1 and 6-month scans post-stroke for Study 1 and between 6 and 7.5-month scans post-stroke for Study 2.
Primary outcome [2] 1007 0
The primary outcome is extent of activation, particularly in ipsilesional primary somatosensory cortex and bilateral secondary somatosensory cortex. This will be assessed between 1 and 6-month scans post-stroke for Study 1 and between 6 and 7.5-month scans post-stroke for Study 2.
Timepoint [2] 1007 0
Assessed between 1 and 6-month scans post-stroke for Study 1 and between 6 and 7.5-month scans post-stroke for Study 2.
Secondary outcome [1] 1897 0
Clinical measures of touch sensation, i.e texture discrimination using the Tactile Discrimination Test and detection of touch pressure using the WEST hand monofilaments.
Timepoint [1] 1897 0
These are assessed at 1, 3, 4.5, 6 and 7.5 months post-stroke.
Secondary outcome [2] 1898 0
Neurological function will be measured using the Neurological Institute Stroke Scale and activities of daily living using the Barthel Index.
Timepoint [2] 1898 0
At 1, 6 and 7.5 months.
