Physical activity did not change at 6 months , and a small to moderate improvement was found at 12 months postsurgery , despite large improvements in quality of life , pain , and physical function .
Reasons for the lack of increased PA are unknown but may be behavioral in nature , as a sedentary lifestyle is difficult to change .
OBJECTIVE Little is known about the extent to which  physical activity ( PA )  levels change following total knee or hip joint replacement relative to pain , physical function , and quality of life .
Our objective was to conduct a systematic review and meta- analysis on changes in PA relative to pain , quality of life , and physical function  after total knee or hip joint replacement .
Effectiveness of a motivational interviewing intervention on weight loss, physical activity and cardiovascular disease risk factors: a randomised controlled trial with a 12-month post-intervention follow-up
Background Intensive diet and physical activity interventions have been found to reduce cardiovascular disease ( CVD ) risk , but are re source intensive . The American Heart Association recently recommended motivational interviewing ( MI ) as an effective approach for low-intensity interventions to promote health-related outcomes such as weight loss . However , there is limited research evaluating the long-term effectiveness of MI-based interventions on health-related outcomes associated with CVD risk . The current research evaluated the effectiveness of a six-month low-intensity MI intervention in a UK primary -care setting in maintaining reductions in CVD risk factors at12 months post-intervention . Methods Primary -care patients were r and omised to an intervention group that received st and ard exercise and nutrition information plus up to five face-to-face MI sessions , delivered by a physical activity specialist and registered dietician over a 6-month period , or to a minimal intervention comparison group that received the st and ard information only . Follow-up measures of behavioural ( vigorous and moderate physical activity , walking , physical activity stage-of-change , fruit and vegetable intake , and dietary fat intake ) and biomedical ( weight , body mass index [ BMI ] , blood pressure , cholesterol ) outcomes were taken immediately post-intervention and at a 12-month follow-up occasion . Results Intent-to-treat analyses revealed significant differences between groups for walking and cholesterol .  Obese and hypercholesterolemic patients at baseline exhibited significant improvements in BMI and cholesterol respectively among those allocated to the intervention group compared to the comparison group . Post-intervention improvements in other health-related outcomes including blood pressure , weight , and BMI were not maintained . Conclusions The present study suggests that a low-intensity MI counselling intervention is effective in bringing about long-term changes in some , but not all , health-related outcomes ( walking , cholesterol levels ) associated with CVD risk . The intervention was particularly effective for patients with elevated levels of CVD risk factors at baseline . Based on these findings future interventions should be conducted in a primary care setting and target patients with high risk of CVD . Future research should investigate how the long-term gains in health-related outcomes brought about by the MI-counselling intervention in the current study could be extended to a wider range of health outcomes
