Effects of Power Ball on Grip Strength in Children With Developmental Delay.

Study Overview
=================
Brief Summary
-----------------
Developmental delay refers to the child who does not perform the normal milestones as other children accomplish in the same age within time or somehow late but can achieve them. While if the delay is found in two or more than two areas of the developmental skill it is known as Global Developmental Delay (GDD). It is divided into mild, moderate and severe developmental delay contributed by many other causes like prenatal, perinatal, postnatal and socioeconomic factors. The objective of the study is to determine the effects of power ball on grip strengthening children with developmental delay. In this study, we will randomly assigned 28 children into two groups, One group will be control group getting the conventional treatment (isometric hand grip training exercises) and other will be experimental group getting the power ball training with conventional treatment. During the sessions hand held dynamometer is use to check the grip strength. By using power ball grip strength in children with Developmental Delay can be improved.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Grip strength by Hand held Dynamometer | A small portable device is held by the examiner and placed against the patient's limb during a maximal isometric contraction. A hand held dynamometer, however, takes the force a patient generates and transmits it through a transducer, quantifies the force, and then presents the data in a digital format. Health professionals can use this muscle strength testing equipment to measure muscle strength efficiently and effectively across the board. The purpose of using a hand dynamometer is to measure the maximum isometric strength of the hand and forearm muscles. The hand dynamometer can be adjusted for hand size and must be calibrated regularly for consistent results | Baseline, 7th and 14th day | 
| Change in ABILHAND-KIDS tool scores | The ABILHAND KIDS was originally developed by using the Rasch measurement model. It allows to convert ordinal score into linear measure located on unidimensional score. Procedure Parents are asked to fill the questionnaire according to child ability to do manual task ,ease in doing fine motor task and difficulty in performing activities, when the task are done1 Without other technical and human help(even if child actually uses help in daily life) 2 Irrespective of the limb actually used to do activity 3 Whatever strategy was used(any compensation is allowed | Baseline and 1 month |
