Primary
| Measure | Time frame |
|---|---|
| Static and dynamic balance evaluation ( in static and 4,7 level of dynamic condition; with both feet under open and closed eyes conditions during a 30 seconds trial). Timepoint: Before and immediately ,48 hours and one week after intervention. Method of measurement: Biodex Balance System (BBS) (302-950 model, Biodex Medical Systems, Inc. 20, New York, USA). | — |
Secondary
| Measure | Time frame |
|---|---|
| Error rate (number of errors/number of auditory signals(during 30 seconds test-7 trial)) during the auditory stroop task in dual take test. Timepoint: Before and immediately ,48 hours and one week after intervention. Method of measurement: Auditory stroop task (AST) written by a programmer and implemented by Matlab (R2018A, Mathworks, Navick, MA, USA) software.;Reaction time during the auditory stroop task in dual take test (the interval between the two consecutive stimuli will be randomized (2,000 ms to 3,000 ms). All reactions with response delays longer than 3,500 ms will be discarded). Timepoint: Before and immediately ,48 hours and one week after intervention. Method of measurement: Auditory stroop task (AST) written by a programmer and implemented by Matlab (R2018A, Mathworks, Navick, MA, USA) software. | — |
