OBJECTIVES: This study sought to analyze the effects of resistance training on functional performance, lowerlimb
loading distribution and balance in older women with total knee arthroplasty (TKA) and osteoarthritis
(OA) in the contralateral knee. In addition, this older knee OA and TKA group (OKG) was compared to older
(OG) and young women (YG) without musculoskeletal diseases who underwent the same resistance training
program.
METHODS: Twenty-three women divided into OKG (N = 7), OG (N = 8) and YG (N = 8) had their functional
performance, lower-limb loading distribution and balance compared before and after 13 weeks of a twiceweekly
progressive resistance training program.
RESULTS: At baseline, the OKG showed lower functional performance and unilateral balance, and impaired
lower-limb loading distribution compared to the OG and the YG (p,0.05). After resistance training, the OKG
showed improvements in functional performance (,13% in sit-to-stand and rising from the floor, ,16% in
stair-climbing and ,23% in 6-minute walking (6 MW)), unilateral balance (,72% and ,78% in TKA and OA
leg, respectively) and lower-limb loading distribution, which were greater than those observed in the OG and
the YG. The OKG showed post-training 6 MW performance similar to that of the OG at baseline. Sit-to-stand
performance and unilateral stand balance were further restored to post-training levels of the OG and to
baseline levels of the YG.
CONCLUSIONS: Resistance training partially restored functional, balance and lower-limb loading deficits in
older women with TKA and OA in the contralateral knee. These results suggest that resistance training may be
an important tool to counteract mobility impairments commonly found in this population.
