Dominant Non-Dominant Upper Extremity in Gender

There are strength and functional differences between non-dominant and dominant extremities. This is important in the hand and extremity rehabilitation process. This situation also differs between genders. Comparison of the dominant and non-dominant limb can provide important clinical or rehabilitation field-related information. It is reported in the literature that manual dexterity, grip strength and joint position sense may differ between extremities. However, the relationship between this situation and the difference between genders has not been explained. It is thought that examining this difference can be extremely useful in determining achievable goals in hand rehabilitation and in customizing care for different groups.

About this study

Many treatment protocols compare the strength of the injured extremity to the uninjured extremity or compare it to normative data from the same group of individuals. There is controversy about the difference in grip strength between dominant and non-dominant hands in left- and right-hand dominant individuals. There is no study in the literature that evaluates the differences in muscle strength, joint position sense and upper extremity function skills between dominant and non-dominant upper extremities between genders. It is very important to include bilateral activity training in rehabilitation programs that aim to improve upper extremity mobility and speed. In addition, it will contribute to the accurate evaluation of activity and participation limitations, the determination of priorities, the selection of the right activity in task-specific and target-oriented treatment approaches, and the achievement of more effective results when integrated with technology-supported approaches. Therefore, the aim of our study is to fill this gap in the literature by comparing the differences between dominant and non-dominant upper extremities between genders.

Treatment and study plan

Primary outcomes

  1. Hand Preference

    Time frame: First Day

    The Edinburgh Hand Preference Questionnaire questions individuals' hand use in daily living activities. The final total score is between 100 and -100. Individuals who score more than 40 points are right-hand; Individuals in this score range from 40 to -40 inclusive are recorded as ambidextrous, and individuals with scores of -40 points and below are left-handed

  2. Grip Strength

    Time frame: First Day

    Hand grip strength was measured using a standard Jamar Dynamometer.

  3. Joint Position Sense

    Time frame: First Day

    Proprioception was assessed by joint position sense (JPS) test. Shoulder JPS was assessed using a digital inclinometer

  4. Manual Dexterity

    Time frame: First Day

    The Purdue Pegboard Test was used to evaluate the functional skill levels of the upper extremities.
