Comparison of the Non-Dominant Hands of Pianists and the Dominant Hands of Individuals Who Do Not Play Instruments

Completed

• Conditions: Hand; Function; Piano Therapy
• Interventions: Other: The same evaluation methods were used for both groups.

• Registration Number: NCT06530355
• Lead Sponsor: Halic University

Brief Summary

The aim of this study is to compare the non-dominant hands of pianists with the dominant hands of individuals who do not play an instrument in terms of skill and reaction time.

Detailed Description

The study was conducted at Haliç University on 15 individuals who have been playing the piano for at least five years (Group 1) and 15 individuals who have never played an instrument in their lives (Group 2). The individuals who agreed to participate in the study and signed the consent form were administered the "Edinburgh Hand Preference Questionnaire" to determine hand dominance, the "Nine-Hole Peg Test" to evaluate hand dexterity, and the "Nelson Hand Reaction Test" to determine reaction time. We believe that the results of our study will provide new perspectives to the literature.Statistical analysis will be performed with SPSS 24.0 program. If the data is parametric, paired sample t-test will be used for within-group evaluation; independent sample t-test will be used for between-group evaluation. If the data is non-parametric, Wilson test will be used for within-group evaluation and Mann Whitney U test will be used for between-group evaluation.

Arm && Interventions

Group	Intervention	Description
Group 1: Pianists	The same evaluation methods were used for both groups.	The non-dominant hands of the pianists in this group were evaluated.
Group 2: Individuals Who Do Not Play Instruments	The same evaluation methods were used for both groups.	The dominant hands of the individuals who do not play instruments in this group were evaluated.

Primary Outcome Measures

Name	Time	Method
Nine-Hole Peg Test	at baseline	It was used to evaluate fine manual skills against time. The participant was asked to place 9 3.2 cm long sticks into the holes on the platform as quickly as possible with his hand and the time from the start command to the last stick was recorded. Then, he was asked to collect the sticks in order with the same hand and the time to remove all the sticks was recorded in seconds.
Edinburgh Hand Preference Questionnaire	at baseline	Used to determine hand dominance. The survey's answer options; the results of the survey were evaluated according to Geschwind's score as follows, in line with the answers given.; * strong right-handers +80 to +100 points; * weak right-handers +20 to +75 points; * ambidextrous -15 to +15 points,; * weak left-handers -20 to -75 points; * strong left-handers -80 to -100 points
Nelson Hand Reaction Test	at baseline	It was used to evaluate reaction time. It consists of a ruler graduated in time. The tester held the ruler by the end between the thumb and index finger of the subject and then released the ruler. The upper point where the subject grasped the ruler with his fingers was recorded.
