About

Scope and Limitations of the Project This project aims to examine the relationship between hand grip strength, trunk control, and functional performance in individuals with mild intellectual disability (MID). Individuals with MID face significant challenges in daily life activities and social interactions due to deficiencies in motor skills. Hand grip strength is considered a fundamental indicator of overall muscle strength and level of independence, while trunk control plays a crucial role in both postural stability and dynamic movement coordination.

The project seeks to scientifically evaluate the physical and functional parameters of these individuals and highlight the impact of motor control on daily living activities. The study is limited to individuals aged 12-18, including those with intellectual disabilities attending rehabilitation centers and healthy individuals visiting hospitals. While this limitation allows for a focused examination of the needs of a specific group, it may also restrict the generalizability of the findings to the broader population.

Full description

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.

Mild Intellectual Disability (MID) in Children

Description:

Mild Intellectual Disability (MID) refers to a neurodevelopmental condition where a child's cognitive abilities and adaptive functioning are below average compared to peers. It typically manifests with an IQ score between 50-70 and difficulties in daily life skills, problem-solving, and academic performance.

Treatment:

Other: Hand grip strength

Normal Development group

Description:

A typically developing child follows expected milestones in physical, cognitive, social, and emotional growth according to age. Their development occurs naturally without significant delays or disabilities.

Treatment:

Other: Hand grip strength
