If u have a small deformity and your grip is weak due to ra .. how can we have a strong grip and stop deformity from developing?

Two steps: 1. Have your rheumatologist check to make sure the RA is well controlled with no active inflammation and also check for any underlying structural damage. 2. Get a referral to a hand therapist for strengthening.

Joint protection: Joint protection and splints may be very helpful. See rheumatologist who has experience with deformity prevention.
