One group (intervention group) receives rehabilitation and the other group (control group) don't receive any intervention, Randomization description: For random allocation, we will use 8 cards A (treatment group) and 8 cards B (control group) and put them in 16 envelopes with the same shape that is not clear inside them. After reshuffling them several times, we will mark them whit serial numbers from 1 to 16. when each participant enters, an envelope is opened and the patient group is determined. N/A Stroke. Intervention 1: Intervention group: auditory lateralization training is performed for 12 sessions of 45 minutes. Auditory stimulus is high-pass and low-pass noise with a cut-off frequency of 2 kHz, which were simulated in 9 hypothetical spatial locations (in the form of 9 speakers in a semicircular horizontal plane) by interaural time difference (ITD) under MATLAB software. The sounds were presented binaurally with different ITDs (0, ±220, ±440, ±660 and ±880 microseconds) at comfortable level via headphones, to induce a sense of displacement of the sound source. Positive and negative numbers and zero indicate stimulus presentation from the right and left angles, and center position, respectively. The subjects should lateralize the sounds and point to a schematic picture of speakers in front of them with right hand. Intervention 2: Control group: they do not receive any intervention. Undecided - It is not yet known if there will be a plan to make this available Justification or reason for indecision in sharing IPD is There is no further information.
