Evalution of hand based on sensation, vibration and grip strength in electricians

Aim: To compare hand based on sensation, vibration and grip strength in normal individuals and electricians using drill machine.
Background: Hand arm vibration syndrome is an occupational disease seen among workers using vibratory tools. These patients experience symptoms of upper limb particularly of hand. Very few studies are been done in workers using low frequency vibratory tools.
Methodlogy: Primary data collection was done using convenient sampling. 60 individuals between 25-35 age group were selected and divided in two groups normal individuals and electricians containing 30 each.Assessment was done using Semmes Weinstein monofilament, jamar dynamometer and 128 Hz tuning fork.
Results: Hand muscle strength, sensation and Vibration sense has shown reduction in electricians compared to normal individuals.
Conclusion: The study concludes that there is decrease in sensation, vibration and grip strength in electricians.
