About this trial
The goal of this observational cross-sectional study is to investigate the relationship between core stability, hand grip strength, and handwriting performance in typically developing school-aged children aged 8 to 12 years. The study aims to determine whether core stability is associated with upper extremity function and handwriting abilities during middle childhood.
The main questions the study aims to answer are:
* Is there a relationship between core stability and hand grip strength in typically developing school-aged children? * Is there a relationship between core stability and handwriting performance in typically developing school-aged children?
Participants will undergo the following assessments:
* Assessment of core stability using the McGill core endurance tests. * Measurement of hand grip strength using a hydraulic hand dynamometer.
Eligibility criteria
This trial accepts healthy volunteersQualifiers
Typically developing children aged 8-12 years.
Both boys and girls.
Enrolled in primary school.
Able to understand and follow simple verbal instructions.
Disqualifiers
History of neurological, developmental, or musculoskeletal disorders affecting posture, upper limb function, or handwriting.
Upper limb pain, deformity, fracture, or injury within the previous six months.
Uncorrected visual or hearing impairment.
Diagnosed developmental coordination disorder (DCD), autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder (ADHD), intellectual disability, or specific learning disorder affecting handwriting.
Trial population
The study population will consist of typically developing school-aged children between 8 and 12 years of age. Participants of both sexes will be recruited according to the predefined inclusion and exclusion criteria. Children with neurological, musculoskeletal, visual, cognitive, or developmental disorders that could affect core stability, hand grip strength, or handwriting performance will be excluded. Written informed consent will be obtained from the parents or legal guardians of all participants before enrollment in the study.

Primary outcomes
1
Core Stability Assessed by the McGill Core Endurance Tests
Core stability will be assessed using the McGill Core Endurance Tests, including the Trunk Flexor Endurance Test, Trunk Extensor Endurance Test, and Side Bridge Test. Each test will be recorded in seconds, with longer endurance times indicating better core stability.

Hand Grip Strength Assessed by a Hydraulic Hand Dynamometer
Hand grip strength will be assessed using a hydraulic hand dynamometer. The maximum grip strength will be recorded for each hand in kilograms (kg).

Handwriting Performance Assessed by the Handwriting Legibility Scale for Children in Elementary School (HLS CHES)
Handwriting performance will be assessed using the Handwriting Legibility Scale (HLS). The scale consists of five components, each rated from 1 to 5, with a total score ranging from 5 to 25. Higher scores indicate poorer handwriting performance. The total HLS score will be used to quantify handwriting legibility.
