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]

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]

The primary outcome is change in intensity, particularly in ipsilesional primary somatosensory cortex and bilateral secondary somatosensory cortex.

Timepoint [1]

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]

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]

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]

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]

These are assessed at 1, 3, 4.5, 6 and 7.5 months post-stroke.

Secondary outcome [2]

Neurological function will be measured using the Neurological Institute Stroke Scale and activities of daily living using the Barthel Index.

Timepoint [2]

At 1, 6 and 7.5 months.
