Relevance. Diabetes mellitus is a group of metabolic disorders wherein hyperglycemia occurs either due to lack of insulin secretion and/or reduced insulin sensitivity of the tissues. One of the commonest complications of diabetes is neuropathy and its severity will depend on how long and how high the hyperglycemia has been prevalent. Chronic hyperglycemia in diabetes affects the peripheral nerves and slows psychomotor responses in persons who do not have proper glycemic control. This decreased psychomotor response because improper glycemic control affects the reaction time in diabetics. Objective: to assess and compare the auditory and visual reaction time in group-1 and group-2 diabetics and to correlate it with glycosylated hemoglobin (HbA1c) levels in both the groups. Methods. The study was conducted on 60 subjects aged between 40-50 years after obtaining the permission of the ethical committee of our institution. The group consisted of 60 well-controlled diabetic patients (HbA1c < 7%) with a history of diabetes for 1-10 years attending the medical OPD of Basaveshwar teaching and general hospital, Gulbarga. Diabetics with HbA1c 5-6% were grouped as group-1 and those with HbA1c 6-7% as group 2. The visual reaction time for a green and red light and auditory reaction time for tone and click sound were measured by using reaction time apparatus 2x4, Anand agencies Pune. HbA1c was done by the micro-column method. Results. The visual and auditory reaction time of diabetics with HbA1c 5-6% was faster as compared to the diabetics with HbA1c 6-7% with P< 0.001 and a statistically significant positive correlation was found between HbA1c levels and the visual and auditory reaction time. Conclusion. Poor glycemic control slows psychomotor responses and thus affects the visual and auditory reaction time.

AbstractObjectivesThe improvement in the/reaction time is important, as it is an indicator of cognitive function. Therefore, there is a need, especially for adolescents in the form of techniques or courses that can improve the reaction time. Yoga was found to cause a better improvement in the health of the individuals. The present study intended to show the effects of Bhramari pranayama (Bhr.P) on reaction time in the healthy adolescents.MethodsOf the 730 potential subjects screened, 520 apparently healthy adolescents randomly assigned to either the Bhr.P group (n-260) or control group (n-260). Bhr.P group practiced the bhramari pranayama for 3 days in a week for 6 months. The Auditory Reaction Time (ART) and the Visual Reaction Time (VRT) were assessed before and after Bhr.P pranayama practice.ResultsBhr.P group shows significant shortening of response time in both VRT (from 267.13 ± 52.65 to 249.87 ± 39.41 ms) and ART (from 237.42 ± 48.12 to 227.91 ± 34.60 ms) after 6 months of Bhr.P practice. In control group subjects, no such significant changes were found (p > 0.05).ConclusionsShortening of RT implies an improvement in the information processing and reflexes. This beneficial effect of Bhr.P on reaction time can be used for improving cognitive function in the adolescents for their academic performances.

Reaction is defined as a behavioral response to a stimulus. The stimulus can be auditory or visual. Reaction time (RT) is determined as the time between the onset of the stimulus and response. According to this definition, the auditory RT is the time between the auditory stimulus and the response. Simple reaction time has been the subject of comparison of many different groups with both auditory and visual stimuli. When the simple auditory and visual RT in normal hearing individuals are compared, it has been observed that the auditory RT is faster than visual reaction. Auditory RT in womens's was observed slower than men. In many different studies, average values are 180-200 ms for visual RT and 140-160 ms for auditory RT with normal hearing and sighted individuals.

The study evaluated the visual and auditory reaction time (simple and choice) in tension type headache patients and healthy controls. Materials and Methods: Study included 21 Tension type headache (TTH) patients in the age group of 21- 49 years and 21 age and sex matched controls. Simple and choice auditory and visual reaction time was recorded using Medicaid Systems RTM-604. The results were statistically analyzed and were recorded as mean ± standard deviation and Student’s unpaired t-test was applied to check the level of significance. Results: The mean values of simple visual reaction time (VRT) and auditory reaction time (ART) were not significantly different in Tension type headache patients and controls. The visual and auditory choice reaction time was longer in TTH patients as compared to controls although not statistically significant. Conclusion: Cognitive and psychomotor impairment has been reported in headache patients. Our findings also indicate delayed central processing in TTH patients and these findings need to be further validated in larger sample size.

Background: The incidence of fatal accidents are more in two wheeler drivers compared to four wheeler drivers. Head injury is of serious concern when recovery and prognosis of the patients are warranted, helmets are being used for safety purposes by moped, scooters and motorcycle drivers. Although, helmets are designed with cushioning effect to prevent head injuries but there are evidences of increase risk of neck injuries and reduced peripheral vision and hearing in helmet users. A complete full coverage helmets provide about less than 3 percent restrictions in horizontal peripheral visual field compared to rider without helmet. The standard company patented ergonomically designed helmets which does not affect the peripheral vision neither auditory reaction time.Objective: This pilot study aimed to evaluate the peripheral field of vision and auditory and visual reaction time in a hypertensive, diabetic and healthy male and female in order to have a better insight of protective characteristics of helmet in health and disease.Method: This pilot study carried out on age matched male of one healthy, one hypertensive and one diabetic and female subject of one healthy, one hypertensive and one diabetics. The field of vision was assessed by Lister’s perimeter whereas auditory and visual reaction time was recorded with response analyser.Result : Gender difference was not noted in peripheral field of vision but mild difference was found in auditory reaction time for high frequency and visual reaction time for both red and green colour in healthy control. But lateral and downward peripheral visual field was found reduced whereas auditory and visual reaction time was found increased in both hypertensive and diabetic subject in both sexes.Conclusion: Peripheral vision, auditory reaction time and visual reaction time in hypertensive and diabetics may lead to vulnerable accident. Helmet use has proven to reduce extent of injury in motorcyclist and other two wheeler drivers.Bangladesh Soc Physiol. 2016, December; 11(2): 43-46

Abstract Background Recent blood pressure guidelines recommend intensive blood pressure control in diabetic patients with cardiovascular disease. Purpose We sought to investigate combined impact of intensive blood glucose lowering and blood pressure control on clinical outcome in diabetic patients with acute myocardial infarction (AMI) has not been fully investigated yet. Method Korean Acute Myocardial Infarction Registry (KAMIR) – National Institute of Health (NIH) database included 12,179 patients (9,046 men; mean age = 63.6±12.6 year-old) who were discharged alive. Among them, 3,430 (28.2%) had a diabetes mellitus (DM). MACCEs were defined as a composition of all cause death, non-fatal MI, repeat revascularizations including repeated percutaneous coronary intervention and coronary bypass grafting, cerebrovascular accident and rehospitalizations at 1 year. This research was supported by a fund by Research of Korea Centers for Disease Control and Prevention. Result We determined cut-off value of discharge systolic blood pressure (SBP) to predict 1-year MACCE in DM and non-DM patients. Discharge SBP of less than 130mmHg was associated with a lower MACCE at 1 year compared to SBP level of 130mmHg or greater (10.8% versus 15.4%; log-rank p=0.001) in DM patients, whereas discharge SBP cut-off level was 140mmHg to discriminate 1-year MACCE in non-DM patients (6.4% versus 8.5%, log-rank p=0.045). In DM patients, there were no significant difference in 1-year MACCEs between patients with HbA1c less than 7% versus 7% or greater (12.0% versus 10.7%; log-rank p=0.325). DM patients were categorized into 4 groups; discharge SBP <130mmHg and HbA1c <7% (Group 1); discharge SBP <130mmHg and HbA1c ≥7% (Group 2); discharge SBP ≥130mmHg and HbA1c <7% (Group 3); discharge SBP ≥130mmHg and HbA1c ≥7% (Group 4). Intensive BP control was associated lower 1-year MACCEs in patients with good glycemic control (Group 1 & 3; 10.7% versus 16.7%; log-rank p=0.009). However, in patients with poor glycemic control, intensive BP control did not improve 1-year MACCEs (Group 2 & 4; 10.6% versus 11.1%; log-rank p=0.761). Conclusion Strict BP control is more important than glycemic control to improve short-term clinical outcome in DM patients with AMI. However, in patients with poor glycemic control, strict BP control did not improve clinical outcome.

Background: Reaction time provides indirect index of processing capability of CNS and also a means of determining sensorimotor performance. The present study was undertaken to study and compare audio and visual reaction time in healthy obese subjects with non-obese subjects. Aims and Objectives: This prospective study was undertaken to find out whether obesity in otherwise healthy individuals is associated with any alteration in auditory and visual reaction time. Materials and Methods: The study involved 100 subjects 50 obese (cases) and 50 non-obese (control) of both sexes within age group 18-60 years. The Anthropometric parameters under study are height in meters, weight in kg to calculate BMI. Then we measured auditory reaction time (ART) and visual reaction time (VRT) and compared in 2 groups. This comparative study was carried out in Dr. S.C.G.M.C, Vishnupuri, Nanded. Results: We have found that auditory and visual reaction time was longer in obese subjects than non-obese control. There was a significant increase in (P<0.05) ART to sufficient sound and significant increase in VRT(P<0.001) to yellow color. Conclusion: We conclude that there is evidence of sensory motor slowing and delay in CNS processing in obesity as suggested by increased reaction time to audiovisual stimuli.

Background: Human beings receive various types of stimuli in day to day life and respond to them accordingly. The time taken to receive a stimulus, it's processing and giving a response is different for every individual at minute level, in milliseconds. This time interval is called reaction time. Various yogic practices are found to influence the Reaction Time of individuals. Aim of the work was to evaluate the immediate effect of deep relaxation technique on auditory and visual reaction time.Methods: Auditory and visual reaction times have been measured using simple reaction time tasks in Inquisit software (version 4.0.10.0). 115 healthy yoga students from SVYASA Yoga university, between the age group of 20 to 50 years were taken for the study. Pre and post measurements of auditory reaction time and visual reaction time was done.10 minutes of pre-recorded DRT was given as intervention and immediately after that reaction times were measured.Results: There was a significant decline in the ART and VRT observed in the Post DRT condition. Statistical analysis was carried out using JASP software.Conclusions: The significant decrease in Auditory and Visual Reaction Time shows that DRT helps to increase the awareness and attention of individuals.

BACKGROUND Information processing has substantial role in performing intellectual activities such as thinking, reasoning, remembering, imagining, or learning. Caffeine being a central nervous system (CNS) stimulant, improves mental performance, especially on alertness, attention, concentration and learning depending on the quantity of intake. In the present study, an attempt was made to study the effect of caffeine on cognitive processing in healthy individuals. METHODS This cross-sectional study was conducted on 50 subjects at Mahatma Gandhi Medical College & Research Institute. Montreal cognitive assessment (MoCA) questionnaire was utilized to assess the level of cognition of each subject. Visual reaction time (VRT), auditory reaction time (ART) and critical fusion frequency (CFF) prior and after consumption of 75 mg of caffeine in 200 ml of milk, pre and post reaction time measurement were taken from the subject to address the difference in reaction time. RESULTS Both visual and auditory reaction time were significantly reduced (P < 0.001) after intake of caffeine. The ability of the subject to appreciate the flickering light stimuli to be steady (critical flicker fusion frequency) had significantly improved to 15 % after caffeine intake. CONCLUSIONS Decrease in visual and auditory reaction and increase in critical flicker fusion frequency values indicate that caffeine increases alertness thereby it may enhance performance efficiency in reasoning, planning, judgment, organizing, concept formation, and problem solving.
