Conclusion Exercises and PA promotion according to public health recommendations  for PA improved cardiovascular fitness , muscle strength and PA behaviour , with moderate effect sizes in people with SpA , RA and HOA/KOA .
Objective To evaluate the effectiveness of exercise and physical activity ( PA ) promotion on cardiovascular fitness , muscle strength , flexibility , neuromotor performance ( eg , balance ) and daily PA in people with rheumatoid arthritis ( RA ) , spondyloarthritis ( SpA ) and hip/knee osteoarthritis ( HOA/KOA ) .
Lower limb muscle strengthening does not change frontal plane moments in women with knee osteoarthritis: A randomized controlled trial.
BACKGROUND Osteoarthritis is a common musculo-skeletal problem accompanied with muscle weakness . Muscle weakness may be readily improved by resistance training . Greater muscle strength has been associated with a lower knee joint loading rate . METHODS We conducted a single-blind r and omized controlled trial of 54 female patients with osteoarthritis in at least one knee , according to the American College of Rheumatology clinical criteria . Patients were r and omized into a 6-month high intensity progressive resistance training or a sham-exercise program . The primary outcomes were first peak knee and hip adduction moment measured using three-dimensional gait analysis at self-selected habitual and maximal speeds . Secondary outcomes were sagittal plane knee and hip moments , peak muscle strength , gait speed , and self-reported knee osteoarthritis symptoms measured by the Western Ontario and McMaster Osteoarthritis Index ( WOMAC ) . FINDINGS Six months of high intensity resistance training did not change the first peak knee or hip adduction moment at either habitual or maximum walking speeds ( P>0.413 ) compared to the sham-exercise . However , the second peak hip adduction moment ( P=0.025 ) and WOMAC pain score ( P<0.001 ) were reduced significantly in both groups over time , but there was no group effect . The changes in the second peak hip adduction moment were inversely related to the changes in the WOMAC pain score ( r=-0.394 , P=0.009 ) . INTERPRETATIONS Muscle strength training in women with osteoarthritis , while effective for reducing osteoarthritis symptoms , appeared to operate through mechanisms other than improved knee or hip joint loading , as paradoxically , improved symptoms were related to decreases of hip adduction moment in late stance
