Effect of Handedness on Handgrip Strength among Left-Handed Normal Girls

Submit Manuscript | http://medcraveonline.com strength provides a valuable and objective index for upper extremity functions. It is a potential tool for clinical assessment as it provides a well established and objective score that is reflective of hand function which is easily and quickly obtainable by different health professionals [3]. The handgrip strength is measured by quantifying the isometric force of the hand musculature around the handle of a dynamometer [4]. Using handgrip dynamometry to assess grip strength is considered a basic standard parameter for the assessment of the functionality of the hand [5].The handgrip strength testing is a valid and reliable easy measure of muscle strength which uncover more than the quality of individual’s handgrip [6]. It helps to establish a database of normal population with reference values [7]. The handgrip strength test is important for selecting the treatment protocol, set realistic goals along the process of rehabilitation, and to predict the overall strength and endurance of the patient [8]. There is a direct connection between hand hold quality, body, wrist and forearm position as hand and forearm muscles are vital in the grasp quality [9]. While some researchers reported that hand dominance had no important influence on grip strength [10-12], others identified significant differences [13].
