MVT: Maximal voluntary torque; VA: voluntary activation; 6MWT: six-minute walk test; WOMAC: McMaster Universities Osteoarthritis Index; STR: strength training group; STAND: standard training group. The numbers of patients in the intervention and standard training groups are displayed at the different times. Values represent mean ± standard deviation. *Significantly different compared to previous measurement for both groups combined (P < 0.05). †Significant difference for groups between T3 and T2 (P = 0.043).
