This study assessed the effectiveness of a six-week balance exercise program on balance parameters and fall frequency in geriatric patients with frailty syndrome. This randomized prospective study evaluated a total of 216 patients after referral to a physical medicine and rehabilitation outpatient clinic. Participants were divided into group 1 (flexibility exercises) and group 2 (balance exercises, including kinesthetic ability trainer [KAT] balance exercises, and flexibility exercises). Both groups performed exercises five days per week for six weeks. Balance assessments included the Berg Balance Scale and time-up-and-go test to evaluate dynamic and functional balance, while the one-leg stand test and KAT 4000 static balance test were done to evaluate static balance. Frailty was observed in 37 (17.12%) patients. Patients without frailty syndrome initially performed significantly better (p˂0.001). Group 2 demonstrated statistically significant improvements after six weeks (p˂0.05). Long-term exercise programs improve balance parameters and exercise performance in older adults with frailty.
