Accelerometer step count accuracy may be affected by gait speed, device positioning, and analysis algorithm selection. We assessed ActiGraph GT3X+ step count accuracy related to device placement and ...analysis algorithm in older adults with walking aids (n = 13) and without walking aids (n = 22). Participants (81.5 ± 5.0 years of age) completed a timed 100-m walk wearing five GT3X+ monitors (hips, ankles, lumbar spine). Individuals with walking aids had slower gait speeds (0.8 ± 0.20 m/s versus 1.2 ± 0.20 m/s without walking aids, p < .001). Intraclass correlation coefficient values for observed versus monitored steps were highest when ankle placement and the low frequency extension (LFE) algorithm were used (left ankle ICC = .989, right ankle ICC = .998). Using the GT3X+ ankle placement and analyzing data with the LFE algorithm resulted in the most accurate step counts in older adults.
Cancer can cause multiple impairments, activity limitations and participation restrictions. According to individual case findings and needs, rehabilitation treatment is varied. The review mainly ...focuses on specific problems. Because of functional deficits cancer patients suffer from persistent emotional and social distress and a reduced quality of life (QOL). QOL encompasses at least the four dimensions of physical, emotional, social and cognitive function, which may be positively influenced by physical exercise. Physical exercise also has been shown to prevent or minimise inactivity/ disuse problems and to reduce fatigue. The management of sexuality dysfunction has to begin with a thorough history taking and a consequent sexuality counselling. The goals of rehabilitation procedures under palliative care are not only to control physical pain but also to help with mental, social and spiritual pain, together with other symptoms. Rehabilitation problems in head and neck cancer, sexuality, lung cancer, prostate cancer, breast cancer and lymphedema can be improved by rehabilitation. The review mainly focuses on impairment and activity limitation. Social, psychological and vocational aspects are left aside in this review.
The objective of this study was to assess qualitative and quantitative patterns of tracer accumulation to increase the diagnostic utility of bone scintigraphy in reflex sympathetic dystrophy (RSD). ...Of 120 patients with high clinical suspicion for RSD, 96 were confirmed as having RSD during follow-up, while the remaining 24 were used as controls. Clinical parameters were measured and correlated to five activity ratios (0-30 s, 0.5-5 min, 5-15 min, 3 h, 24 h) and five scintigraphic signs. Monitoring three dynamic phases revealed different tracer kinetics of potential diagnostic utility; however, the 24-h bone phase offered no additional diagnostic contribution and can be omitted. Quantification provided objective parameters for the duration of symptoms, pain and impairment of movement but not for surface temperature differences, swelling and impairment of physical force. It is of limited use for diagnosis except for the exclusion of disease. Discriminant analysis revealed the combination of three signs (diffuse uptake in carpus/tarsus+diffuse uptake in all small joints+increased activity ratio in the late blood pool phase) to be the pattern with the highest diagnostic accuracy independent of localisation, sex, age and precipitating factors. It is concluded that the scintigraphic confirmation of RSD is based on lateralisation in the late blood pool phase and the described pattern in the early bone phase.
