Development of an equipment to improve neural control & eye hand coordination: A pilot study

Background: Eye–hand coordination is the coordinated control of eye movement with hand movement, and the processing of visual input to guide reaching and grasping along with the use of proprioception of the hands to guide the eyes. Eye hand coordination may vary because of age, hand dominance, type of vision, fatigue, exercise, sleep deprivation, alcohol. Eye hand coordination can be measured by different ways, such as alternate Hand Wall Toss Test and upper extremity motor control testing Device. The study objective is to develop a new equipment, establish reliability of the new equipment and to document reference values. Materials and method: a experimental design with construction validity. Age - 18-35 year healthy individuals both male and female were included to avoid study bias. Subjects with recent upper limb fractures and any visual disturbances were excluded from the study. Results: The total number of subjects was 707, including 356 male and 351 female. The SPSS Software Packaged was used. Conclusion: The study was concluded that small OD Ring total number of error 3 is normal, time taken for first error 4-5 sec is considered as good, the distance required to reach the First Error 8-13cm is good and Total time spend to complete task is 14-18sec is consider as a normal for small ring. For Medium OD Ring total number of error 2 is good, Time taken for first error 3-5sec is normal, the distance required to reach the First Error 8-16cm is good, total time spend to complete task is 12-15sec is normal. Large OD Ring total number of error, 2 is good, time taken for first error 3-4sec is good, the distance required to reach the First Error 4-14cm is normal, total time spend to complete task is 11-15sec is normal. Clinical Importance: Applications of the tool in the field of Physiotherapy for measuring, training and improvement of eye hand coordination. Future research: Testing can be done using non dominant hand and multiple directions.
