    Physical activity and implications on well-being in mild Alzheimer's disease: A qualitative case study on two men with dementia and their spouses2010In: Physiotherapy Theory and Practice, ISSN 0959-3985, E-ISSN 1532-5040, Vol. 26, no 4, p. 226-239Article in journal (Refereed)
    Abstract [en]

    To improve the understanding of experiences of people with mild Alzheimer's disease (AD) and their significant others, related to the physical activity of the afflicted persons and its perceived importance. A qualitative case study design was used. The study comprised two men with mild AD and their wives. Data were collected by qualitative interviews and participant observations. Data analysis followed a thematic guideline as described by Braun and Clarke ( 2006 ). Three central themes of experiences related to physical activity in AD were identified: 1) physical activity as health reinforcement; 2) barriers to physical activity; and 3) adaptation strategies. Important motivations for outdoor walks were enjoyable experiences of nature, body movement, and positive attitudes toward physical activity. Several factors were experienced as barriers to physical activity (e.g., tiredness, difficulties in finding one's way, and "peculiar behavior"). Significant others made considerable adjustments in everyday life to enable their partners to retain a physically active lifestyle. The findings indicate that in persons with AD, physical activities such as outdoor walking can play an important part in everyday life by creating meaningful routines and improving experienced well-being and health.

    Movement control tests for the lumbopelvic complex. Are these tests reliable and valid?2017In: Physiotherapy Theory and Practice, ISSN 0959-3985, E-ISSN 1532-5040, Vol. 33, no 5, p. 386-397Article in journal (Refereed)
    Abstract [en]

    This study evaluated inter- and intra-observer reliability and discriminative validity of three movement control tests: 1) standing knee-lift test; 2) static lunge test; and 3) dynamic lunge test. Thirty-eight subjects, 21 with low-back pain and 17 healthy, were video-recorded while performing the tests. Four physical therapists scored the tests according to a standardized protocol and calculated a composite score for each test based on the number of incorrect test components. Inter-observer reliability for the composite scores ranged between 0.68 and 0.80 (ICC 2,k) and intra-observer reliability between 0.54 and0.82 (ICC 2,1). The separate test components ranged between 0.32 and 0.91 (κfree) for inter-observer reliability and 0.42 and1.00 for intra-observer reliability. Test components showing the highest values were: back extension; arm lowering; and shoulders moving backwards. Components hip hitch, trunk lateral flexion, knee not lifted straight up and hips moving backwards did not reach accepted thresholds. Discriminative validity ranged between 0.47 and 0.56 (AUC). As our results showed an overall good agreement for the composite, scores and for the majority of the included test components the tests can be considered reliable enough. As the tests' discriminative ability was close to "none", they should, however, not be used for diagnostic purposes but should be further evaluated toward predicted validity.
