AIM: In the present experiment we investigated how closely grip strength corresponded to two different positions of wrist joint · In neutral position · In dorsiflexion of 25o-35o with Ulnar deviation 10o-15o MATERIAL & METHODS: In this study 200 male subjects with uninjured wrist joint in the age group of 20-50 years from the villages of Karunakaracherry and Annamedu in Pattabiram, Chennai, were selected. The grip strength of the dominant hand is measured using Jamar Dynamometer in second handle spacing. Three measurements of grip strength are taken in each position of wrist joint, average of this is taken for calculation. A rest time of 1 minute was given in between two measurements RESULT: The Mean grip strength of dominant hand when wrist joint was held in neutral position was 36.425 kgs with S.D = 4.588 and when the wrist joint was held in Extension (25o-35o) with Ulnar deviation (10o-15o) it was 39.384 kgs with S.D = 4.497. The comparison shows that there is a significant change in the grip strength of 2.959 kgs between the two positions of the wrist joint. The calculated t-value of 29.4641 shows that there is statistical significance, at P < 0.005 (5 % level) CONCLUSION: This study concludes that the grip strength in dominant hand was higher when the wrist joint was held in Extension (25o-35o) with Ulnar deviation (10o-15o) position than when it is held in neutral position.
