Background: Swiss ball exercise is used as a rehabilitative tool to correct posture and to treat and prevent pain in neck and waist, because it can increase muscle strength, endurance, flexibility, and coordination and be used to improve perceptual balancing ability. In the present study, we aimed to investigate the effects of activities on different sizes of Swiss ball on balance in geriatric population. Method: In this experimental study 30 elderly people in the age of 65–80 years participated. Subjects were equally divided in 2 groups. Group A having 15 subjects are given Swiss ball exercises on 55 cm Swiss ball for 4 weeks (4 days/week). Group B having 15 subjects are given exercises on 75 cm Swiss ball for 4 weeks (4 days/week). Berg Balance Scale (BBS) scores were noted both before and after the 4 weeks exercises session on Swiss ball. Pre-exercise evaluation was done. Then the post-exercise evaluation was done. Subjects were evaluated using BBS. Result: Thirty patients in the age range 65–80 years participated in the study. Patients were given Swiss ball activities. Within the group the pre-intervention BBS was 36.2 ± 5.11 and the post-intervention was 41.4 ± 6.32 (t-value is 3.25, p-value is 0.05) for 55 cm diameter Swiss ball. There is significant difference with in the groups with respect to mean BBS scores. Within the group pre-intervention BBS was 37.6 ± 5.40 and post-intervention was 45.6 ± 4.27 (t-value is 1.94, p-value is 0.05) for 75 cm Swiss ball. There is no significant difference with in the groups with respect to mean BBS scores. Between the two groups the post intervention BBS was 41.4 ± 6.32 the Swiss ball of 55 cm and 45.6 ± 4.27 for Swiss ball of 75 cm (t-value is 0.041, p-value is 0.05). There is no significant difference in the BBS scores. Conclusion: There was positive improvement in Berg balance score by Swiss ball training on 55 cm diameter of swiss ball. There was no positive improvement in Berg balance score by Swiss ball training on 75 cm diameter of swiss ball. There was no improvements seen when both the Swiss ball regimes are compared.
