The world we live in is designed for right handedness as most tools and daily appliance are designed for the right hand. Environmental factors also affect the differences between hands. Some researchers believe that maximal voluntary muscle force (especially grip force) only has a mild level of lateralization. Д«ilateral asymmetry in grip strength may be attributed to the central mechanism of the origin of handedness and lateralization of functions in the brain. The rule suggests that the dominant hand is 10% stronger than the non-dominant hand. The classic 'ten percent rule' servers this purpose. Therefore, some guidance is required for comparison of the grip strength of the damaged and intact hands. Problems arise when this is not the case. This is useful when initial muscle strength is equal in both hands.

Second, in unilateral limitation of hand functions the strength of the two hands can be compared. Therefore, this approach gives only approximate degree of hand weakening due to pathological conditions. However, prediction of this initial level of grip strength may present some problems due to several reasons.ДЇirst, comparison of hand strength of a person with reference values may not be very useful due to high variability of this parameter within reference populations. The goal of patients with limitation of hand functions is physical rehabilitation to restore upper extremity strength to the pre-injury or pre-illness level.

Hand and forearm create the grip strength, while the extensor muscles of the forearm stabilize the wrist. In gripping activities, the flexor muscles in the The synergistic action of flexor and extensor muscles and the interplay of muscle groups is an important factor in the strength of resulting grip. The grip strength is affected from many conditions and muscle strength is one of these factors. The estimation of hand grip strength is of immense importance in assessment of disability ratings and in determining the efiency of different treatment strategies of hand and also in evaluation of, patients rehabilitation effectiveness with damaged upper extremity, neurological and neuromuscular disorders, stroke, cerebral palsy, and etc. Maximal grip strength measurements are commonly used as an objective index of the functional integrity of the upper extremity and indicator of overall health, nutritional status and physical fitness of people.

Grip strength is critical in various daily life, social and professional activities as well as in manual actions in physical culture and sport. The results suggest that distinction between stronger hand and hand preferred for skilled activities should be made and considered when predicting the bilateral asymmetry in the MGS and assessing limitations in hand strength. This study compares dominant and non-dominant hand strength in right-, left-, and mixed handed participants. Key words: bilateral asymmetry, maximal grip strength, dynamometry, handedness Novgorod branch, Sochinskiy State University N.
