Brief Summary:
Asymmetries in both physiology and anatomy at different levels of the central nervous system which controls the upper extremities are well-established These asymmetries related to handedness are evident in the motor cortex and corticospinal tract Moreover variances have been identified in peripheral nervous pathways including elevated sensory detection thresholds and increased conduction velocities in the motor nerve of the dominant arm
Apart from disparities in the nervous system differences also arise in the muscles Prolonged preferential utilization of muscles on the dominant side of the body may lead to alterations in muscle fiber composition characterized by a higher predominance of slow-twitch type I fibers
Modern technology plays a key role in daily human life This involves keeping pace with rapid changes in the field of communication technology In this context smartphones have become an essential part of life not only in matters related to communication but also as essential social accessories As a result of this social involvement in communication technology young children have become avid smartphones users Holding a phone in hand needs support from fingers flexion of hand and wrist so holding the phone in same position for long periods can cause huge amount of stress on the structures present in the hand This stress can cause injuries and damages in longer periods
To address this objective we will examine muscle synergies on the dominant sides in right-handed and left-handed participants while performing upper limb motor tasks To accomplish this we will conduct the following Comparative analysis of motor and sensory nerve conduction velocities radial median and ulnar in right-handed and left-handed individuals during smartphone use Comparison of hand muscle activation between right-handed and left-handed individuals during smartphone use

Detailed Description:
Handedness is a well-recognized behavioral phenomenon characterized by a preference for using one hand over the other This study investigates the impact of handedness on electromyographic EMG activity of hand muscles and nerve conduction velocity during smartphone use
This interventional parallel study included 70 participants 35 left-handed 35 right-handed aged 12 - 14 years inclusion criteria normal BMI 165-24 kgm² no regular athletic activity Participants shared the same socioeconomic level used the same smartphone model 67-inch touchscreen
Exclusion criteria included
peripheral nerve injury upper extremity movement limitations history of upper extremity fractures or deformities neurological disorders such as peripheral neuropathy due to type I diabetes mellitus
EMG activity and nerve conduction velocities radial median and ulnar nerves will be measured before and during smartphone use Muscle activation will be assessed for the abductor pollicis longus APL extensor carpi radialis ECR flexor carpi ulnaris FCU and first dorsal interosseous muscles Statistical analysis will be conducted to identify significant differences between left-handed and right-handed participants
