Osteoarthritis (OA) is a highly prevalent disease among older adults ( Lawrence et al., 2008 ) and one of the leading causes of functional loss and disability ( Cross et al., 2014 ). Physical activity has been deemed crucial to optimal health outcomes, which has led to federal recommendations for

Knee osteoarthritis (OA) represents an increasing burden in developed countries ( Arden & Nevitt, 2006 ). Progression of knee OA is usually assessed using radiographic scores such as the Kellgren & Lawrence scale (K&L-score) ( Kellgren & Lawrence, 1957 ). Radiographic scores correlate to some

Results from instrumented gait analysis vary between test situations. Subject characteristics and the biomechanical model can influence the total amount of variability. The purpose of this study was to quantify reliability of gait data in general, and with respect to the applied model, and investigated population group. Reliability was compared between a functional and a predictive gait model in subjects with knee osteoarthritis and healthy controls. Day-to-day consistency for sagittal plane variables was comparable between models and population groups. Transversal plane variables relative to joint excursion showed larger inconsistency for repeated measures, even for a more sophisticated biomechanical approach. In conclusion, the presented reliability data of sagittal plane kinematics should be used for a reasonable interpretation of results derived in clinical gait analysis. Variables of the transversal plane should not be used as long as sources of error are not sufficiently minimized.

Background:

Older adults with osteoarthritis (OA) often report that their disease symptoms are exacerbated by weather conditions. This study examines the association between outdoor physical activity (PA) and weather conditions in older adults from 6 European countries and assesses whether outdoor PA and weather conditions are more strongly associated in older persons with OA than in those without the condition.

Methods:

The American College of Rheumatology classification criteria were used to diagnose OA. Outdoor PA was assessed using the LASA Physical Activity Questionnaire. Data on weather parameters were obtained from weather stations.

Results:

Of the 2439 participants (65–85 years), 29.6% had OA in knee, hand and/or hip. Participants with OA spent fewer minutes in PA than participants without OA (Median = 42.9, IQR = 20.0 to 83.1 versus Median = 51.4, IQR = 23.6 to 98.6; P < .01). In the full sample, temperature (B = 1.52; P < .001) and relative humidity (B = –0.77; P < .001) were associated with PA. Temperature was more strongly associated with PA in participants without OA (B = 1.98; P < .001) than in those with the condition (B = 0.48; P = .47).

Conclusions:

Weather conditions are associated with outdoor PA in older adults in the general population. Outdoor PA and weather conditions were more strongly associated in older adults without OA than in their counterparts with OA.

Key Points ▸ Patients with medial knee osteoarthritis experienced significantly decreased levels of pain and improved levels of function when utilizing a valgus knee brace. ▸ A combination of a valgus knee brace and other orthoses may be more effective in reducing symptoms and improving function

Knee osteoarthritis (OA) is a degenerative disease, and it usually affects medial tibiofemoral and patellofemoral compartmants. 1 Sixty-five percent of people with knee pain over 50 years or older have OA. 2 The main symptoms of OA are pain and physical disability. 3 The pathogenesis of OA is
