Tokyo, Sept. 20 -- UMIN Clinical Trials Registry (UMIN-CTR) received information related to the study (UMIN000062995) titled 'A study of galvanic vestibular stimulation for impaired awareness of hemiplegia after stroke' on Sept. 20.
Study Type:
Interventional
Study Design:
Basic Design - Single arm
Randomization - Non-randomized
Blinding - Open -no one is blinded
Control - Uncontrolled
Primary Sponsor:
Institute - Kansai Electric Power Hospital
Condition:
Condition - Anosognosia for hemiplegia following ischemic or hemorrhagic stroke
Classification by malignancy - Others
Genomic information - NO
Objective:
Narrative objectives1 - The primary objective of this study is to explore the effects of adding galvanic vestibular stimulation to usual rehabilitation on the severity of anosognosia for hemiplegia in patients with ischemic or hemorrhagic stroke. The secondary objectives are to evaluate changes in unilateral spatial neglect, motor function, activities of daily living, and cognitive function, as well as the persistence of the intervention effects and the feasibility of galvanic vestibular stimulation.
Basic objectives2 - Efficacy
Intervention:
Interventions/Control_1 - A single-arm intervention with an A-B-A-prime phase structure in which galvanic vestibular stimulation is added to usual rehabilitation. The study period is 6 weeks. During the A phase (weeks 1-2), participants receive usual rehabilitation alone, including lower-extremity muscle strengthening, balance training, and gait training. During the B phase (weeks 3-4), galvanic vestibular stimulation is added to usual rehabilitation using the Intelect Advance Combo combination electrotherapy system (Chattanooga; medical device certification number: 220AIBZX00049000). Participants receive stimulation in a seated position with 3 x 3 cm electrodes placed over the bilateral mastoid processes. Stimulation is delivered for 15 minutes once daily on weekdays, 5 days per week for 2 weeks, for a total of 10 sessions. The stimulation intensity is individually adjusted within a tolerable, non-discomfort range based on the sensory threshold measured before the intervention and participant tolerability; the target intensity is approximately 1.5 mA. During the A-prime phase (weeks 5-6), participants receive usual rehabilitation alone again.
