Introduction
Hand and finger strength is important as it is required for day to day activities. One of the most common methods of measuring muscle strength is by using a handgrip dynamometer. Hand grip strength is an indicator of muscle power. Pin dexterity & finger taping is a term used to explain a range of different hand abilities and performances.
Aim
To compare the Maximum Voluntary Contraction (MVC), Pin Dexterity test (PDT) and Finger tapping (FT) in skilled and non skilled persons.
Methodology
50 skilled persons (computer operator) & 50 non skilled persons aged between 18-40yr in Narayana Medical Collage & Hospital were selected. Informed consent was taken. All the subjects underwent a detailed clinical examination before being included in the study as per the study protocol. Institutional ethical clearance was taken. MVC, PDT & FT were measured in skilled and non skilled persons (50 in each group) by using digital hand grip dynamometer, computerized finger tap recorder and modified O'Connor finger dexterity device which was in house built and calibrated.
Results
MVC values were 22Kg ± 9.2 and 26 Kg ± 12.6, PDT scores were 67± 7.9, & 66 ± 9.1 FT count was 111 ± 29.8 and 108 ± 29.2 in skilled non skilled persons. In both the groups there was-ve correlation between MVC & PDT & +ve correlation between MVC & FT. Whereas-ve correlation between MVC & PDT among 50 skilled persons.
Conclusion
Fine motor skill such as FT & PDT improves by decreasing the muscle strength in skilled persons when compared to non skilled persons.
