Statin Use and Knee Osteoarthritis Outcomes: A Longitudinal Cohort Study
2018
Objective: Statins have several pleiotropic effects, but the literature regarding the possible relationship between use of statins and outcomes in knee osteoarthritis (OA) is limited. The aim of this study was to investigate whether statin use is associated with a lower risk of radiographic OA (ROA), radiographic symptomatic knee OA, and pain in North American individuals. Methods: A total of 4,448 community-dwelling adults from the Osteoarthritis Initiative were followed for 4 years. Statin use (including the time from baseline and the type of statin) was defined through self-report information and confirmed by a trained interviewer. Knee OA outcomes included incident ROA, symptomatic knee…
Cardiac involvement in rheumatoid arthritis: Evidence of silent heart disease
1995
Background : Rlieumatoid arthritis (RA) is a systemic disease involving many organ systems and is frequently accompanied by cardiac alterations. However, there is considerable disagreement concerning the cardiac abnormalities found in patients with RA. The purpose of our investigation was to determine, by a non-invasive method such as echocardiography, the nature and extent of cardiac involvement in RA patients with no symptoms of cardiac disease, in comparison with a control sample. Methods : We selected 35 patients affected by rheumatoid arthritis (five men, 30 women), aged 51 ± 11 years. No patient had either symptoms of cardiac disease or extra cardiac complaint. As a control group we s…

Loading and gait symmetry during level and stair walking in asymptomatic subjects with knee osteoarthritis: importance of quadriceps femoris in reduc…
2007
Repetitive impulsive forces during walking are claimed to result in joint osteoarthritis (OA). The aim of this study was to investigate impact loading and gait symmetry during level and stair walking in asymptomatic elderly subjects with knee OA. It was hypothesised that pre-activity of the quadriceps femoris muscle (QF) would be an important factor reducing impulsive loading when walking on level ground. Subjects [21 female, six men, 66.2 (7.6) years] were studied. The subjects had no knee pain or diminished functional capacity, but showed radiographically light or moderate bilateral knee OA changes. Ground reaction forces (GRFs), plantar pressure distribution, muscle activation pattern [v…
Physical Function and Properties of Quadriceps Femoris Muscle in Men With Knee Osteoarthritis
2008
To examine the objective physical function of the lower extremities, to measure the properties of quadriceps femoris muscle (QFM), and to assess subjective disabilities in men with knee osteoarthritis (OA) and to compare the results with those obtained from age- and sex-matched control subjects.Cross-sectional study.Rehabilitation clinic in a university hospital.Male volunteers (n=54) (age range, 50-69y) with knee OA and randomly selected healthy, age- and sex-matched control subjects (n=53).Not applicable.Physical function evaluated with a test battery including the QFM composition measurement, the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and the RAND 36-Item…
Prospective associations of cardiovascular disease with physical performance and disability
2019
Background: Literature regarding cardiovascular disease (CVD) and incident physical performance limitations and disability in older people is equivocal. Aims: This study aimed to investigate whether CVD is longitudinally associated with incident physical performance limitations and disability in a large population-based sample. Methods: This was an 8‑year prospective study using data collected as part of the Osteoarthritis Initiative. Participants were community-dwelling adults with knee osteoarthritis or at high risk for this condition. Diagnosed CVD was self-reported. Physical performance was assessed with measures of chair stand time and gait speed, whereas disability was assessed with t…
The ceiling effects of patient reported outcome measures for total knee arthroplasty
2020
Abstract Background Patient reported outcome measurements (PROMs) that exhibit a substantial ceiling effect show clustering of participant's scores towards the upper limit of a scale and consequently have low discriminatory power among high end scores. This study aimed to compare ceiling effects at 1 and 2 years postoperatively across commonly usedPROMs for TKA. Hypothesis We hypothesized, that the analyzed PROMs differ substantially in regards to their ceiling effect. Patients and methods Patients that underwent a primary unilateral TKA and completed pre-operative and post-operative questionnaires were included in the analysis. Participants completed the KOOS, KOOS-12, KOOS-JR, KOOS-PS, WO…
Maintenance of aquatic training-induced benefits on mobility and lower-extremity muscles among persons with unilateral knee replacement.
2011
Abstract Valtonen A, Poyhonen T, Sipila S, Heinonen A. Maintenance of aquatic training-induced benefits on mobility and lower-extremity muscles among persons with unilateral knee replacement. Objective To evaluate the maintenance of observed aquatic training-induced benefits at 12-month follow-up. Design Twelve-month follow-up of a randomized controlled study. Setting Research laboratory and hospital rehabilitation pool. Participants Population-based sample of 55 to 75-year-old women and men 4 to 18 months (on average 10mo) after unilateral knee replacement. Fifty people were willing to participate in the exercise trial and 42 people in the follow-up study. Intervention Twelve-month follow-…
Effects of aquatic resistance training on mobility limitation and lower-limb impairments after knee replacement.
2010
Abstract Valtonen A, Poyhonen T, Sipila S, Heinonen A. Effects of aquatic resistance training on mobility limitation and lower-limb impairments after knee replacement. Objective To study the effects of aquatic resistance training on mobility, muscle power, and cross-sectional area. Design Randomized controlled trial. Setting Research laboratory and hospital rehabilitation pool. Participants Population-based sample (N=50) of eligible women and men 55 to 75 years old 4 to 18 months after unilateral knee replacement with no contraindications who were willing to participate in the trial. Interventions Twelve-week progressive aquatic resistance training (n=26) or no intervention (n=24). Main Out…
Efficacy of a 12-month, monitored home exercise programme compared with normal care commencing 2 months after total knee arthroplasty: A randomized c…
2013
Objective: To evaluate the efficacy of a delayed home exercise programme compared with normal care after primary total knee arthroplasty. Design: Single-blind, prospective, randomized, controlled trial. Participants: A total of 108 participants (61% females, mean age 69 years [standard deviation 8.7]), were randomized to a home-based exercise group (EG, n=53) or to a control group (CG, n=55). Methods: Two months post-operatively, the EG received a home exercise programme, while the CG received no additional guidance. The outcome measurements were: pain and disability, measured using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC); healthrelated quality of life (HR…
