NCT03019432 | Unknown

Brief Summary

In this study, the researchers will investigate whether the E-effect is present in stroke subjects both on the subjective visual and postural vertical test. In addition, researchers will investigate the impact of the loss of different sensory information sources on the sensory reweighting strategies and perception of verticality by measuring the effect of somatosensory loss on the E-effect.

Conditions

Sensory Disorder; Stroke; Cerebrovascular Disorders

Outcome Measures

Primary Outcomes (3)

• Rivermead Assessment of Somatosensory Performance

  This test assesses several modalities of somatosensory performance such as sharp/dull discrimination; warm/cold; proprioception; 2-point discrimination.

  1 day

• Subjective Visual Vertical Test (SVV)

  This test measures the ability of the subject to realign a laser bar with the earth vertical after the malalignment procedure. This test occurs in complete darkness to inhibit visual references. The device used for the projection is the Vertitest (Difra, Belgium).

  1 day

• Subjective Postural Vertical Test

  This test measures the ability of the subject to realign a chair, at which the subject is seated, with the earth vertical after a malalignment procedure. This test occurs blindfolded to inhibit visual references. The tilting chair used for this test is custom made. The deviation/error of the realigned chair compared to the earth vertical is measured by a digital protractor.
