BACKGROUND There is overwhelming evidence of the benefits of physical activity and the physical environment is increasingly recognized as a promising determinant of physical activity participation. The influence of the environment on physical activity has not been evaluated among black Africans and no specific measure exists for assessing environmental factors related to physical activity in an...

Tactile memory is the crucial factor in coding and transfer of the semantic information through a single vibrator. While some simulators can produce strong vibro-tactile sensations, discrimination of several tactile patterns can remain quite poor. Currently used actuators, such as shaking motor, have also technological and methodological restrictions. We designed a vibro-tactile pen and softwar...

BACKGROUND Effective treatment of chronic fatigue syndrome (CFS) with cognitive behavioural therapy (CBT) relies on a correct classification of so called 'fluctuating active' versus 'passive' patients. For successful treatment with CBT is it especially important to recognise the passive patients and give them a tailored treatment protocol. In the present study it was evaluated whether CFS patie...

BACKGROUND To create and find accurate and reliable instruments for the measurement of physical activity has been a challenge in epidemiological studies. We investigated the reliability and validity of two different physical activity questionnaires in 71 adolescents aged 13-18 years; the WHO, Health Behaviour in Schoolchildren (HBSC) questionnaire, and the International Physical Activity Questi...

One of the PDA forensic issues is the difficulty in maintaining image integrity as two consecutive acquisitions on most PDA platforms could produce different images. JFFS2 used in certain Linux PDA further complicate the forensic process as compression is implemented in this file system. Currently there is not specific tool that can analyse this file system. This paper analyse the integrity of ...

OBJECTIVE To compare the Body mass index, airway Obstruction, Dyspnea, and E xercise capacity (BODE) index scores and its individual components between COPD patients with and without severe physical inactivity, as well as to correlate the number of steps/day with scores of physical activity questionnaires, age, and the BODE index (including its components). METHODS We included 30 patients, wh...

OBJECTIVES To develop a transcultural adaptation of the Leisure Time Physical Activity Instrument (LTPAI) and the Physical Activity at Home and Work Instrument (PAHWI) in Spanish and to assess their psychometric properties in women with fibromyalgia syndrome (FS). DESIGN A cross-sectional transcultural adaptation and validation study. SETTING Testing was completed at the university. PARTI...

BACKGROUND Physical activity (PA) is frequently restricted in people with multiple sclerosis (PwMS) and aiming to enhance PA is considered beneficial in this population. We here aimed to explore two standard methods (subjective plus objective) to assess PA reduction in PwMS and to describe the relation of PA to health-related quality of life (hrQoL). METHODS PA was objectively measured over a...

OBJECTIVES To investigate the reliability and an aspect of validity of a modified version of the long International Physical Activity Questionnaire (Hausa IPAQ-LF) in Nigeria. DESIGN Cross-sectional study, examining the reliability and construct validity of the Hausa IPAQ-LF compared with anthropometric and biological variables. SETTING Metropolitan Maiduguri, the capital city of Borno Stat...

BACKGROUND The Physical Activity and Sedentary Behaviour Assessment Questionnaire (PASBAQ), used within the Health Survey for England (HSE) at 5-yearly intervals, is not included annually due to funding and interview-length constraints. Policy-makers and data-users are keen to consider shorter instruments such as the Short-form International Physical Activity Questionnaire (IPAQ) for the annual...
