PARKİNSON HASTALARINDA FARKLI DENGE DURUMLARINA GÖRE GÖVDE KONTROLÜNÜN, EL FONKSİYONUNUN ve EL REAKSİYON ZAMANININ KARŞILAŞTIRILMASI

Abstract

Objective This study aims to compare trunk control, manual dexterity, and reaction time according to different balance states in people with Parkinson's Disease (PwPD). Material and Method A total of 25 PwPD, 6 of whom were women, were included in the study. Individuals were divided into the Moderate-risk group (n=11) and the Low-risk group (n=14) according to the Berg Balance Scale (BBS) cut-off scores. To evaluate trunk control and functions, static and dynamic sitting balance were evaluated with the Trunk Impairment Scale (TIS), which consists of trunk coordination sub-parameters. Hand grip strength was measured with the Jamar hand dynamometer, manual dexterity was measured bilaterally with the Purdue Pegboard Test, and hand reaction time was measured bilaterally with the the Ruler Drop Test. Results When the groups were compared for trunk control, there was a significant difference in the dynamic sitting subparameter and the total score of the trunk impairment scale in favor of the low-risk group (p=0.030, p=0.005). However, there was no difference between the groups in static sitting and coordination sub-parameters (p=0.181, p=0.558). There was no difference between the groups in the grip strength, dexterity, and reaction time of both hands (p>0.05). Conclusion While the dynamic sitting balance and trunk impairment of the moderate-risk balance group was worse than the low-risk group, manual dexterity and reaction time were similar. Further studies are needed to examine manual dexterity for trunk and distal mobility, which play a key role in proximal stabilization and balance in PwPD.
