“…After verification of eligibility, demographic and physical data were collected from all participants. Their dominant UL was determined as the limb most frequently used to write 15 , while the dominant LL as the one they would more easily kick a ball 16 . In total, 40 subjects were included, whose demographic and physical characteristics are given in Table 1 .…”

Background Tests that are usually employed for the clinical assessment of muscular strength have notable disadvantages. The Modified Sphygmomanometer Test (MST) is a promising method because it is low-cost and provides objective measures. Objectives To investigate the most adequate method and sources of outcome values for the assessment of strength with the MST. Method Methodological study with 40 healthy adults (22.98±2.26 years), who did not practice physical activity regularly. The strength of the flexors and extensors of the elbow and knee, the handgrip of the dominant side and anterior trunk flexors were randomly assessed with portable dynamometers and the MST (bag and cuff adaptations, and sphygmomanometer without adaptation) by a single examiner. An independent examiner read and recorded the values. The sources of the investigated outcome values were the first trial and the means of two and three trials. One-way ANOVAs and Pearson Correlation Coefficients were used for the analyses (α=0.05). Results For the MST methods applied to assess all muscular groups, similar values were found for all sources of outcome values (0.01

“…Although somewhat unconventional, this kind of approach follows a fruitful line of investigations using pattern recognition analyses of fine motor control for biomedical applications. This has been the case for example for studying Parkinson disease (Van Gemmert et al, 2003), Alzheimer disease (Werner et al, 2006), and schizophrenia (Caligiuri et al, 2009), as well as for designing neuropsychological tests (Fairhurst et al, 2008; O'Reilly and Plamondon, 2010a) for the detection of various health problems or for the recovery from injuries (Yancosek and Mullineaux, 2011). …”

This paper uses human movement analyses to assess the susceptibility of brain stroke, one of the most important causes of disability in elders. To that end, a computerized battery of nine neuromuscular tests has been designed and evaluated with a sample of 120 subjects with or without stoke risk factors. The kinematics of the movements produced was analyzed using a computational neuromuscular model and predictive characteristics were extracted. Logistic regression and linear discriminant analysis with leave-one-out cross-validation was used to infer the probability of presence of brain stroke risk factors. The clinical potential value of movement information for stroke prevention was assessed by computing area under the receiver operating characteristic curve (AUC) for the diagnostic of risk factors based on motion analysis. AUC mostly varying between 0.6 and 0.9 were obtained, depending on the neuromuscular test and the risk factor investigated (obesity, diabetes, hypertension, hypercholesterolemia, cigarette smoking, and cardiac disease). Our results support the feasibility of the proposed methodology and its potential application for the development of brain stroke prevention tools. Although further research is needed to improve this methodology and its outcome, results are promising and the proposed approach should be of great interest for many experimenters open to novel approaches in preventive medicine and in gerontology. It should also be valuable for engineers, psychologists, and researchers using human movements for the development of diagnostic and neuromuscular assessment tools.

“…Survivors of cerebrovascular accidents or amputation involving the dominant hand are forced to transfer their handwriting skills to their nondominant hand (injury-induced hand dominance transfer, I-IHDT). This typically takes several months of training by occupational therapists (Harada, Okajima, & Takahashi, 2010), and the overall success is highly subject-dependent (Pereira, Raja, & Gangavalli, 2011;Yancosek & Mullineaux, 2011).…”

We examined whether intermanual transfer of fine motor skills can be facilitated by training in a virtual environment. We focused on three types of assistance: visual - subjects could see a reference template on a computer screen - and two variants of haptic assistance. Subjects held a planar robot manipulandum and were required to write isolated cursive letters of an approximate size of 5 cm. Therefore, the task was similar to writing on a horizontal blackboard. The robot generated forces that were directed either towards the reference template (path guidance) or towards the reference trajectory (trajectory guidance). The training protocol consisted of three assisted exercise sessions on three consecutive days. Performance on the following day was tested to assess retention. After training, the improvement in trajectory shape was only significant in trajectory guidance and, to a lesser extent, visual guidance. Path guidance exhibited no significant improvement. These effects were substantially retained one day after the end of training. Similar effects were observed in shape variability. Furthermore, all training modalities caused a reduction in movement duration, but no significant differences were observed among groups. These results suggest that robot assistance may be beneficial for improving intermanual transfer, but inclusion of temporal information in the guidance strategy is essential for learning to take place.
