These exercises improve spinal flexibility, strengthen muscles around spine, and correct muscle imbalance9). Various exercise programs have previously been studied and their effects reported10–16). For such programs, equipment such as the Swiss ball and the sling are quite often used. However, few studies have compared exercise programs and active exercise programs in terms of their use of equipment, how well they stimulate muscle contraction, and whether they are effective in improving scoliosis patients’ balancing ability. For that reason, the present study investigates the effect of Swiss ball exercise and resistance exercise on the static balancing ability of scoliosis patients.
