“…Such devices have been used to assess periods of activity, both among persons with TFA [25,[39][40][41][42] and in other populations [43][44][45]. Although using activity monitors in research is becoming increasingly common [46], outcomes obtained by such devices are often restricted by the period of use.…”

Abstract-Although physical limitations associated with transfemoral amputation (TFA) have been studied in laboratory settings, little is known about habitual activity within free-living environments. A retrospective analysis of 12 mo of step activity data was performed to quantify activity levels, variations, and patterns in 17 adults with unilateral TFA. Yearly, seasonal, and monthly average daily step counts and coefficients of variation (CoVs) were examined to characterize mobility. Analysis by Medicare Functional Classification Level (MFCL) was performed to explore relationships between clinical classification and performance. Subjects averaged 1,540 prosthetic steps/day, and activity generally increased with MFCL. Activity between MFCL-2 and -3 subjects was not significantly different, suggesting that ability to engage in habitual physical activity may be similar for these groups. Relative variation (CoV) was 0.65 across subjects but was lower for those with higher activity levels. No significant differences in CoV by group were detected. Marked seasonal and monthly patterns in activity were identified. Warmer seasons and months generally promoted higher activity, but peak temperatures and humidity depressed activity. Results suggest that persons with TFA are greatly limited in regards to activity. Further, large variations within and between subjects may challenge the interpretation of step activity gathered over short periods of time.

“…With the improvement of prognosis in haematological malignancies, programs to improve physical health through walking and other forms of physical activity may become an increasingly important component in continuing care programs [11,17]. Ultimately, the choice of which instrument or method is the best to assess patients' level of physical activity is a function of the research question, participant burden and available resources to the researcher or the practitioner [37]. The results of this study indicate that the SAM represents an additional approach to assessing in more detail the physical activity behaviour of the HSCT patient group, that it does not cause unnecessary or excessive discomfort to the patients, and that it contributes information independent of that provided by self-report measures and in-clinic performance tests.…”

N K (2010). The relationship between ambulatory step activity, self-reported physical functioning and standardised timed walking in patients with haematological malignancies. Disability and Rehabilitation, 32(22):1819-1826. Postprint available at: http://www.zora.uzh.ch Similarly, ambulatory activity monitoring did not correlate significantly with self-reported functional status in patients with chronic obstructive pulmonary disease. [20] To the best of our knowledge, only one previous report has investigated the relationship between ambulatory step activity monitoring, self-reported physical functioning and the 6-minute standardized walking test in cancer patients.[28] There was moderate agreement between the 7-Day Physical Activity Recall and the accelerometer with longitudinal serial correlation coefficients of 0.54 (baseline), 0.24 (year 1), and 0.53 (year 2), all p-values <0.01.To summarize, the association observed between self-reported physical functioning, standardized timed walking and the outputs of ambulatory step activity varies from none to almost perfect in studies of various chronic disease populations. Only one study has investigated this issue in cancer patients, and none among HSCT patients. The aim of the current study was to determine the degree of association between self-reported physical functioning, standardized timed walking and the outputs of ambulatory step activity monitoring among outpatients with haematological malignancies recovering from HSCT. Methods ParticipantsThis study presents a cross-sectional analysis of baseline data collected from a subset of 117 ambulatory hematological patients after completion of HSCT at the University HospitalZurich and the Cantonal Hospital of St. Gallen, Switzerland. These baseline data were 4 collected before the patients were randomized between an ambulatory physical exercise intervention and a usual care (i.e., non-exercising) control group. Adult patients were considered eligible for the study if they had completed their HSCT treatment. Patients were excluded from the study in case of graft versus host disease (GVHD) except for grade I not requiring treatment, painful joints, instable osteolyses, chronic pain, lesions of the central or peripheral nervous system, uncontrolled cardiovascular disease, thyroid disease or diabetes.The study was approved by the local ethical committee. All patients provided written informed consent. MeasurementsAmbulatory step activity levels were assessed with the Step Activity Monitor 3 (SAM3, Cymatech Corporation, Seattle, WA, USA). The patients were instructed to wear the SAM3 for 7 consecutive days. Activity monitoring over a 7-day period has previously been found to result in reliable and representative measures of an individual's movements on a day-to-day basis.[17] All participants were instructed to leave the SAM3 on the ankle if they had to rest or lay down during the day and to perform their daily activities as usual. The parameters assessed by the SAM3 for this study were: (1) `average steps/day`, (2) ...

“…Estudos populacionais apontam uma frequência média de 7000 a 13000 passos diários em adultos de 20 a 50 anos aparentemente saudáveis. Já na população com DM, estudos apontaram média de 6291 passos/dia 13 . Apesar da manutenção de um estilo de vida ativo ser considerado uma importante estratégia de tratamento não medicamentoso do DM e de complicações associadas 1 , a avaliação do nível de AFH em pacientes diabéticos atendidos pelo sistema público de saúde não é comum na prática clíni-ca.…”

IntroduçãoA morbidade e mortalidade associadas ao diabetes são significativas e crescentes 1 . O envelhecimento da população, o aumento das taxas de obesidade, inatividade física e o crescimento populacional são características esperadas para alavancar a prevalência do diabetes mellitus (DM). Segundo estimativas atuais, 382 milhões de pessoas são portadoras de DM e a previsão é que esse número atinja mais de 590 milhões em ResumoO aumento das atividades físicas habituais (AFH), como a caminhada e as consequentes contrações musculares delas oriundas, pode ser considerado uma estratégia de auxílio do controle metabólico em diabéticos. Apesar disso, complicações como a polineuropatia periférica simétrica distal (PSD) em pessoas com diabetes podem contribuir diretamente para a redução dos níveis da AFH. Com isso, o objetivo do presente estudo foi avaliar e comparar variáveis sanguíneas e o nível de AFH estimado por número de passos em diabéticos portadores e não portadores de PSD. Vinte e sete diabéticos, sendo 14 não portadores e 13 portadores de PSD atendidos no Centro Hiperdia de Viçosa, foram avaliados quanto ao nível de atividade física habitual estimada por número de passos/dia através de pedômetros. Cada participante utilizou o equipamento durante sete dias e os dados relacionados a cinco dias de semana e dois dias do final de semana foram analisados. Além disso, foram submetidos à avaliações antropométricas e bioquímicas. Não foram observadas diferenças significativas nas variáveis antropométricas e bioquímicas entre os grupos. O grupo sem PSD apresentou médias de passos em 7 dias, nos dias de semana e dias de final de semana estatisticamente superiores ao grupo com PSD (p<0,05). Apesar do grupo sem PSD ser mais ativo, os dois grupos apresentam baixos níveis de AFH estimada por número de passos/dia, evidenciando a necessidade de elaboração de programas educacionais de atividades físicas específicos para ambas as populações.
