Home Exercise To Increase Hand Function

Introduction

 The hand is a very complex part of human body with multiple joints, different types of ligaments, tendons and nerves.Hand is an essential organ in all our daily activities and with continuous use there is a high risk of injury occurring in our hands.  

Definition of hand function

Hand function involves the hand performing meaningful movements such as reaching for object,holding,releasing object and manipulation of objects  in performing purposeful tasks. 

Grip can be divided into power grips and precision grips. Types of power grips are cylindrical grip,sphiral grip and hook grip.Examples are pulling a rope, holding a large ball ,opening a bottle or carrying a suitcase.Meanwhile types of precision grip are pincer grip and lateral pinch.Examples are turning a key, holding a pen or turning pages in a book and holding a plate

All these grips will become meaningless if the hand has no ability to release the grip. All grips require muscle strength,sensation ,coordination  and stability of the whole arm.
