Objective. To describe self-reported physical activity and physical fitness and to identify correlates of physical activity and general health perception. Methods. Data on self-reported physical activity, physical fitness, activity performance, and disease activity were collected from a sample of 298 patients with rheumatoid arthritis (RA). Results. Forty-seven percent of our sample reported physical activity behaviors that did not comply with public health recommendations. A majority of the patients had decreased lower-limb muscle function (72%), grip force (94%), joint motion (94%), and functional balance (68%). Correlations between self-reported physical activity and other variables were r s ‫؍‬ 0.25 or less. Variation in general health perception was explained (total adjusted R 2 ‫؍‬ 0.65) by pain and activity performance. Conclusion. Our findings indicate that there is a case for recommendations on and support for healthy physical activity behaviors among people with RA.

Objective. To revise the content of the Functional Index in myositis (FI) and to evaluate measurement properties of a revised FI. Methods. Previously performed FI (n ‫؍‬ 287) were analyzed for internal redundancy and consistency, and ceiling and floor effects. Content was evaluated and a preliminary revised FI was developed. To evaluate the construct validity of the preliminary revised FI, it was compared with isokinetic measurements of muscular strength and endurance, the Myositis Activities Profile, disease impact on general wellbeing, and creatine phosphokinase levels. Minor adjustments were made and the revised FI was investigated for interrater reliability and intrarater reliability over a 1-week period. After this, some minor, additional adjustments were made leading to the final version, FI-2. Results. Five tasks were removed from the original FI due to ceiling effects. Performance pace and number of repetitions were modified for the remaining tasks. A moderate correlation (r s ‫؍‬ 0.58) was found between the shoulder flexion task of the preliminary revised FI and isokinetic measurements of shoulder flexion endurance. Intraclass correlation coefficient (ICC) for interrater reliability of the revised FI varied from 0.86 -0.99 with no systematic differences. ICC for intrarater reliability varied from 0.56 -0.99 with systematic differences (P < 0.05) between test and retest in 3 of the tasks. The sit-up task was excluded due to low intrarater reliability resulting in the final 7-item FI-2. There was a good correlation between tasks on the right and left side suggesting that the FI-2 could be performed unilaterally. Conclusion. The FI-2 is a valid and reliable outcome measure of impairment for patients with polymyositis or dermatomyositis. It is well tolerated and the unilateral FI-2 requires a maximum of 20 minutes to perform. Further evaluation of sensitivity to change and testing in healthy individuals needs to be conducted.

The aim of this study was to survey rheumatoid arthritis patients' conceptions of their management of everyday life. Interviews with nine female, functionally independent patients with rheumatoid arthritis (median age 46 years, median duration of symptoms 6 years) were analysed using a phenomenographic methodology. Uncertainty was a central theme of the thoughts of all nine patients. Conceptions of needs accentuated after the onset of the disease, and mediated by uncertainty, were categorised, as were conceptions of strategies/attitudes for satisfying the needs and/or reducing uncertainty. A theoretical framework is presented, and recommendations for physical therapy are made.

The aim of the study was to assess the effects of once-weekly, intensive dynamic training in water of patients with Rheumatoid Arthritis (RA). Thirty patients with RA, functional class II, in a training group (TG) and 30 in a comparison group (CG) were assessed with respect to clinical, radiological and functional disease manifestations and psychosocial consequences before and after a four-year training period. After the training period the TG patients had significantly better grip strength and higher activity level, the latter maintained at two-year follow-up. There were significantly more CG patient admittances for acute hospital care during the training period. No other differences between the groups were found. Dynamic training at an intensive tempo does not seem, even in a long perspective, to lead to any undesirable consequences.
