Comparison of Upper Extremity Functions of Physiotherapy Students
Comparison of Upper Extremity Functions of Physiotherapy Students With Different Hand Preferences
The purpose of this cross-sectional, comparative study is to comprehensively evaluate and compare upper extremity functions among physiotherapy students with different hand preferences. Handedness is a fundamental neuromotor characteristic that significantly influences upper extremity functions, including muscle strength, motor skills, coordination, and movement speed. These differences in motor performance can have prominent implications in professional fields like physiotherapy and rehabilitation, which demand a high level of manual dexterity, hand-eye coordination, and precise motor control during clinical applications.
While previous literature has predominantly focused on isolated measures such as grip strength, multi-dimensional studies that concurrently evaluate hand preference, objective motor performance, strength, and self-reported functional status remain limited. This study aims to fill this gap by determining whether significant differences exist in strength, performance, and functional levels between right-handed and left-handed individuals within a specialized student population.
A total of 42 physiotherapy and rehabilitation students aged 18 and older will be recruited through convenient sampling. Hand preference and lateralization will be objectively determined using the Edinburgh Handedness Inventory, categorizing participants based on their Laterality Quotient (LQ). Upper extremity functional levels, manual dexterity, and strength will be thoroughly evaluated. Self-reported upper extremity disability will be measured using the Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) questionnaire. Performance-based manual dexterity and functional capacity will be objectively assessed using the Jebsen-Taylor Hand Function Test, which measures the time taken to complete seven simulated activities of daily living. Gross grip strength will be measured with a Jamar hand dynamometer, and fine pinch strength will be quantified using a pinchmeter. All assessments will be performed under standardized environmental conditions with dedicated, trained assessors to ensure high measurement reliability. The outcomes will provide critical insights into neuromotor control strategies and potential ergonomic adjustments needed for left-handed students during their clinical training.

Manual Dexterity and Hand Function
Délai: At baseline (single session assessment)
|
Assessed using the Jebsen-Taylor Hand Function Test (JTHFT), which consists of seven subtests simulating daily activities (writing, card turning, picking up small objects, stacking checkers, simulated eating, moving light objects, and moving heavy objects).
The completion time for each subtest is recorded in seconds, with shorter times indicating better functional performance.

Grip and Pinch Strength
Délai: At baseline (single session assessment)
|
Gross grip strength is measured in kilograms using a Jamar hand dynamometer, and fine pinch strength is quantified using a pinchmeter.
The average of three trials for each measurement is recorded
|
At baseline (single session assessment)

Self-Reported Upper Extremity Disability
Délai: At baseline (single session assessment)
|
Assessed using the Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) questionnaire.
It is an 11-item self-report tool where total scores are converted to a scale ranging from 0 to 100.
A score of 0 indicates no disability (best possible outcome), while a score of 100 represents the most severe upper extremity disability (worse outcome).
Higher scores mean worse functional limitation.
