Effect of Liuzijue Exercise Combined with Elastic Band Resistance Exercise on Patients with COPD: A Randomized Controlled Trial

Figure 3

The 6MWD, 6MWD%pred, 30 s SST, and hand grip strength in the CG, LG, and LEG groups after a six-month training period. CG, control group; LG, Liuzijue exercise group; LEG, Liuzijue exercise combined with elastic band resistance exercise group; 6MWD, 6-min walking distance; 6MWD%pred, 6-min walking distance as a percentage of the predicted value; 30 s SST, 30 s sit-to-stand test. Notes: < 0.05 within-group comparisons and < 0.01 within-group comparisons.
