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 ) .
Effects of weight-bearing versus nonweight-bearing exercise on function, walking speed, and position sense in participants with knee osteoarthritis: a randomized controlled trial.
OBJECTIVE To investigate whether weight-bearing ( WB ) exercise enhances functional capacity to a greater extent than nonweight-bearing ( NWB ) exercise in participants with knee osteoarthritis . DESIGN R and omized controlled trial . SETTING Kinesiology laboratory . PARTICIPANTS Participants ( N=106 ) were r and omly assigned to WB exercise , NWB exercise , or a control group ( no exercise ) . INTERVENTION WB exercise and NWB exercise groups underwent an 8-week knee extension-flexion exercise program . MAIN OUTCOME MEASURES Western Ontario and McMaster Universities Osteoarthritis Index ( WOMAC ) function scale , walking speed , muscle torque , and knee reposition error were assessed before and after intervention . RESULTS Equally significant improvements were apparent for all outcomes after WB exercise and NWB exercise , except for reposition error , for which improvement was greater in the WB exercise group . In contrast , there were no improvements in the control group . CONCLUSIONS Simple knee flexion and extension exercises ( WB and NWB ) performed over 8 weeks result ed in significant improvement in the WOMAC function scale and knee strength compared with the control group . NWB exercise alone may be sufficient enough to improve function and muscle strength . The additional benefit of WB exercise was improved position sense , which may enhance complex walking tasks ( walking on figure of 8 route and spongy surface )
