Brief Summary

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.

Outcome Measures

Primary Outcomes (3)

• Mean Hand Grip Strength in kilograms (kg)

  Hand grip strength will be measured using a standard Jamar dynamometer in a seated position, with the elbow flexed at 90 degrees. The best of three consecutive trials for each hand will be recorded and averaged. Unit of Measure: kilograms (kg)

  Baseline (Day 0) and Week 8

• Trunk Control Test Score (0-100 points)

  Trunk control will be evaluated using the Trunk Control Test (TCT), which assesses four functional movements: rolling to the weak side, rolling to the strong side, sitting up from lying down, and maintaining a sitting position. Each task is scored, and total scores range from 0 to 100. Unit of Measure: points (0-100)

  Measured at baseline (Day 0) and at the end of the 8-week intervention period (Week 8)

• Total Functional Independence Measure (FIM) Score

  Functional performance will be assessed using the Functional Independence Measure (FIM), which evaluates self-care, mobility, communication, and social cognition. Scores range from 18 to 126, with higher scores reflecting greater independence. Unit of Measure: points (18-126)

  Baseline (Day 0) and Week 8

Study Arms (2)

Mild Intellectual Disability (MID) in Children

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.

Other: Hand grip strength

Normal Development group

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.

Other: Hand grip strength

Interventions

Hand grip strength OTHER

Collection Tools a) Hand Grip Force Measurement: Hand grip strength will be measured using a digital dynamometer. The measurement will be performed three times in the dominant and nondominant hand of the participant and the average value will be taken (1). b) Trunk Control Assessment: Trunk control will be assessed with the McGill core endurance test. This scale is a valid and reliable tool to objectively measure trunk stability and dynamic control levels (2). c) Motor skill assessment: Timed Up and Go Test: The Timed Up and Go Test was used to assess functional mobility and dynamic balance (3). The patient was told to get up from the chair, walk 3 meters, return and sit back in the chair. The time was recorded. Timed Stair Climbing Test: It consists of the individual climbing the stairs and returning to the starting point. The elapsed time was recorded
