The Treatment Effectiveness of Combined tDCs and Neurofeedback (NF) for Patients With Cognitive Deficits After Stroke

Kowloon Hospital, Hong Kong45 enrolled

Overview

This is a double blinded, randomized control trial with a pretest-posttest control and interventional groups design. Both the assessor and participants are blinded to all assessments and evaluations. All patients with subacute stroke undergo in-patient or out-patient rehabilitation are screened initially by a series of screening test. Suitable patients are assigned randomly to 3 groups respectively. Group 1 is the combined transcranial direct current stimulation (tDCS) and neurofeedback group. Group 2 is the neurofeedback group. Group 3 is the control group with sham neurofeedback training.

Treatment sessions for all three groups are conducted by the investigators who has training in neurofeedback and transcranial direct current stimulation (tDCs). Each participant performed 10 training sessions on different days. Sessions were conducted 3-5 times a week The tDCS + neurofeedback group will carry out 30 minutes tDCS and 30 minutes neurofeedback training. The real neurofeedback group will carry out 30 minutes neurofeedback training. The sham neurofeedback group will conduct the 30 minutes sham neurofeedback training.

Outcomes

Primary Outcomes

Change score in Trail Making Test A & B from baseline

Trail Making Test is a neuropsychological test of visual attention and task switching. It consists of two parts in which the subject is instructed to connect a set of 25 dots as quickly as possible while still maintaining accuracy.

Time frame: One day before the treatment , up to 4 weeks, up to 16 weeks

Secondary Outcomes

Change score in Functional Independence Measure (FIM) from baseline

The Functional Independence Measure instrument is a basic indicator of patient disability. FIM is used to track the changes in the functional ability of a patient during an episode of hospital rehabilitation care.

Time frame: One day before the treatment , up to 4 weeks, up to 16 weeks

Change score in Stroke Adapted 30 item version of the Sickness Impact Profile (SA - SIP 30)

SA-SIP 30 assesses quality of life in patients who have sustained a stroke.

Time frame: One day before the treatment , up to 4 weeks, up to 16 weeks
