Using raw, sub-second level, accelerometry data, we propose and validate a method for identifying and characterizing walking in the free-living environment. We focus on the sustained harmonic walking (SHW), which we define as walking for at least 10 seconds with low variability of step frequency. Approach. We utilize the harmonic nature of SHW and quantify local periodicity of the tri-axial raw accelerometry data. We also estimate fundamental frequency of observed signals and link it to the instantaneous walking (step-to-step) frequency (IWF)...

Functional (psychogenic) tremor is the most common functional movement disorder. Characteristic clinical features, so called red flags, can help to make the clinical distinction of this type from other tremor disorders. The most common features include the variability of frequency and amplitude. Clinical examination should include different types of distraction including motor or cognitive tasks or testing the influence of suggestibility on tremor amplitude, frequency or direction. Patients often report sudden onset and remissions that may last for months or even years...

Outdoor playtime has been highly correlated with moderate-to vigorous-intensity physical activity (MVPA), while also being associated with decreased sedentary time. This systematic review and meta-analysis sought to examine the physical activity levels and sedentary time of young children (2-5years) during outdoor play periods at centre-based childcare. Eight online databases were searched for peer-reviewed, English-language, original research. Two reviewers independently extracted data (study design, participants, method of measurement, and physical activity and/or sedentary time of participants)...

The clinical differentiation of the tremor in Parkinson's disease (PD) and essential tremor (ET) can sometimes be challenging, especially in the early stage of the disease. As different neural oscillators are involved in the generation of these two types of tremor, their trajectorial analysis could also be different. The goal of this study was to investigate whether some disease-specific patterns related to their tremor trajectories in fact exist. The three-axial accelerometer signals of the hand tremor obtained from a total of 369 participants [49 with PD, 25 with isolated resting tremor (iRT), 133 with ET, and finally 162 normal subjects with physiological tremor (Ph)] were subjected to vector analysis using a custom-made mathematical program...
