| Summary: | Although communication problem is the main defect resulted fromhearing impairment, other physical problems may be associated with it. Theaim of this study was to investigate the performance of upper extremity inmale and female hearing-impaired and normal-hearing students with YBalance Test of Upper Quarter (YBT-UQ). The sample was comprised of 80students including 40 congenital severe to profound hearing-impaired girlsand boys (age: 18.10±2.77 yr and 17.95±2.56 yr) and 40 normal-hearinggirls and boys (age: 17.55±0.60 yr and 17.60±0.56 yr) who were selected bythe purposive non-random method from normal and deaf high schools inGuilan province. Subjects' personal information, height, weight and medicalrecords were collected using their medical profiles. The YBT-UQ was usedto evaluate the performance of upper extremity in the closed kinematicchain under medial, inferior – lateral and superior – lateral directions. Tocompare the groups' performance and directions, one-way ANOVA wasused while paired t test was used to compare dominant and non-dominantextremity. Results revealed no significant difference between theperformance of dominant and non-dominant upper extremities in all groups(P0.05). There were significant differences among the four groups: boyswithout hearing-impairment, boys with hearing-impairment, girls withouthearing-impairment, and girls with hearing-impairment performed better(P<0.05). However, only the difference between normal-hearing andhearing-impaired girls was not statistically significant (P0.05). Inconclusion, there was no difference in performing YBT-UQ between
dominant and non-dominant upper limbs; therefore, this test can be used toevaluate and examine the injured limb. Also, regarding the defect in thedynamic balance performance of hearing-impaired subjects and the effect ofgender on this defect and the importance of the upper extremity in dailyroutines, it is necessary to design and implement plans aiming at improvingtheir performance. |
