Effect of Cold & Hot Temperature On Hand Grip Strength In Normal Individuals : Cross Sectional Study
Keywords:
Thermometer, Jamar dynamometer, Temperature, Hand gripAbstract
Background: Heating or cooling of muscle tissue has been used for decades to obtain specific therapeutic objectives. Hand grip strength can be quantified by measuring the amount of static force that the hand can squeeze around a dynamometer. Therefor the purpose of this study was to determine the immediate effect of heat and cold application upon hand grip strength measured with dynamometer. Procedure: written informed consent was obtained from all the participants. Skin sensation was checked. Pre intervention grip strength was assessed for individual asked to dip hand in cold water (15°C) for 30 seconds, then immediately after grip strength was assessed. Pre-intervention grip strength was assessed for both the groups individuals asked to dip hand in hot water (40°C-42°C) for 30 seconds then immediately after grip strength was assessed. Result: on comparing normal grip strength with warm water there was slight increase in grip strength which was statistically not significant. On comparing normal grip strength with cold water there was slight decrease in grip strength that was statistically significant. Conclusion: From our study, we found that Hot water increases hand grip strength as compared to cold temperature in normal individual.
