Effect of chiropractic care on hand eye coordination in reaching movements

Abstract

Background: Humans undergo a constant strive of adapting to cope with the changing environment. Human brain has the ability to integrate sensory information with motor control to bring out precise and meaningful reaction to stimuli. This study investigates the impact of chiropractic care on visumotor adaptation in terms of hand eye coordination in subject who undergo the visuomotor adaptation task of reaching movements studied for the performance variables of reaction time, movement time and learning index Methodology: 34 subjects were divided in two groups to perform visuomotor adaption task that was measured in terms of reaction time, movement time and learning index to investigate the difference in performance with and without intervention; intervention group (n=17) that received chiropractic care and then took visuomotor adaptation task and control group (n=17) that did not receive any intervention and preformed the visuomotor adaptation task only. Results: The results revealed that the subject in interventional group performed better in term of reaction time, movement time and learning index. Subjects in the interventional group showed a low reaction time at the start of the task (F(1, 32)= 5.52, P=0.025) which means they took less time to react to the stimulus and showed faster movements at the start of the experiment (F(1,32)=5.77, P=0.02) [subjects in rotation block 1] and F(1,32)=4.21 ,P=0.04) [subjects in rotation block 2], results were significantly different for _______________________________________________________________________Abstract xv subjects during end of the experiment [block 6] (F(1,32)= 2.375, P=0.134). Subjects in interventional group showed higher learning index as compared to subjects in control group, (F(1,32)=4.8, P=0.03). Conclusion: The study showed significant results in terms of decrease in reaction time, faster movements and better performance at the start of the experiment post spinal and sacroiliac adjustment. Further research can elucidate the underlying biochemical and neurological mechanisms responsible for enhanced sensorimotor integration
