The Relationship Between Hand Grip Strength, Trunk Control and Functional Performance in Individuals With Mild Mental Retardation

Purpose of the Study The aim of this study is to determine the relationship between hand grip strength, trunk control, and functional performance in individuals with mild intellectual disability. In this regard, the study aims to examine the physical factors affecting motor control and functional independence in these individuals. By revealing the impact of hand grip strength on trunk stability and overall functional capacity, the study seeks to contribute to the development of specialized rehabilitation programs for these individuals. Research Question Is there a significant relationship between hand grip strength, trunk control, and functional performance in individuals with mild intellectual disability? Hypotheses H0 (Null Hypothesis): There is no relationship between hand grip strength, trunk control, and functional performance in individuals with mild intellectual disability. H1 (Research Hypothesis): There is a positive and significant relationship between hand grip strength, trunk control, and functional performance in individuals with mild intellectual disability. Objectives of the Study To measure hand grip strength in individuals with mild intellectual disability and compare it with the normal population. To determine trunk control levels in these individuals and examine its relationship with hand grip strength. To assess functional performance (level of participation in daily living activities) and determine its correlation with hand grip strength. To identify the key physical parameters that should be emphasized in rehabilitation programs based on the findings. Significance of the Study Motor control and functional limitations commonly observed in individuals with mild intellectual disability can negatively affect their participation in daily life activities. Hand grip strength is a crucial indicator of both overall muscle strength and independence in daily activities. The results of this study could provide a scientific basis for developing physical rehabilitation and occupational therapy approaches tailored for individuals with special needs. Additionally, this research aims to highlight the importance of targeted interventions to improve the quality of life for these individuals. By focusing on a specific population, this study seeks to provide practical and applicable findings and serve as a reference for similar studies conducted in specialized centers.
