“…In this study, the authors associate the rostral region of the primary motor cortex (M1) with the movement commands while the caudal region and some spinal nerves intervene in both posture control and movement ( Shadmehr, 2017 ). Other studies have identified a deterioration in the tonic contraction capabilities of elderly people ( Cogliati et al., 2019 ), suggesting that this behavior is to be attributed to changes in the peripheral properties of motor units. Following this, we removed some older subjects from our analysis, even though on our set-up their results were comparable to those of younger subjects.…”

In recent years, several studies have investigated upper-limb motion in a variety of scenarios including motor control, physiology, rehabilitation and industry. Such applications assess people’s kinematics and muscular performances, focusing on typical movements that simulate daily-life tasks. However, often only a limited interpretation of the EMG patterns is provided. In fact, rarely the assessments separate phasic (movement-related) and tonic (postural) EMG components, as well as the EMG in the acceleration and deceleration phases. With this paper, we provide a comprehensive and detailed characterization of the activity of upper-limb and trunk muscles in healthy people point-to-point upper limb movements. Our analysis includes in-depth muscle activation magnitude assessment, separation of phasic (movement-related) and tonic (postural) EMG activations, directional tuning, distinction between activations in the acceleration and deceleration phases. Results from our study highlight a predominant postural activity with respect to movement related muscular activity. The analysis based on the acceleration phase sheds light on finer motor control strategies, highlighting the role of each muscle in the acceleration and deceleration phase. The results of this study are applicable to several research fields, including physiology, rehabilitation, design of robots and assistive solutions, exoskeletons.

“…Interested persons were fully informed with a detailed information sheet and gave written informed consent prior to the onset of their participation in the study. To be included in the study persons had to fulfill following criteria: ( Park, 2000 ) in-patient stay in the orthopedic and geriatric rehabilitation clinic Dussnang, ( Seidler et al, 2010 ) age ≥ 50 years, ( Valenzuela et al, 2018 ) able to score ≥ 20 on the Mini Mental State Examination (MMSE), ( Cogliati et al, 2019 ) able to provide a signed informed consent, ( Reuter-Lorenz et al, 2015 ) physically able to stand for at least 3 min without external support (self-report). Exclusion criteria were: ( Park, 2000 ) mobility or cognitive limitations or comorbidities which impair the ability to use the training games and overall system, ( Seidler et al, 2010 ) conservatively treated osteoporotic fractures, ( Valenzuela et al, 2018 ) previous or current major psychiatric illness (e.g., schizophrenia, bipolar disorder, recurrent major depression episodes), ( Cogliati et al, 2019 ) history of drugs or alcohol abuse, ( Reuter-Lorenz et al, 2015 ) terminal illness, ( Kramer et al, 1999 ) severe visual (e.g., especially achromatopsia) and auditory impairments, ( Khow and Visvanathan, 2017 ) insufficient knowledge of German to understand the instructions/games.…”

“…The aging process is accompanied by a decline in physical and cognitive functions such as balance, gait, executive functions and psychomotor speed ( Kramer et al, 1999 ; Park, 2000 ; Seidler et al, 2010 ; Reuter-Lorenz et al, 2015 ; Valenzuela et al, 2018 ; Cogliati et al, 2019 ). These declines often lead to loss of independence in daily life, restricted social participation and are major risk factors for accidental falls ( Rowe and Kahn, 1997 ; Kramer et al, 1999 ; Herman et al, 2010 ; Khow and Visvanathan, 2017 ).…”

Objective: The aim of this pilot randomized clinical trial was to test the feasibility and efficacy of an exergame-based cognitive-motor training program in geriatric inpatients.Methods: The study participants were randomly allocated to either the exergame intervention group or the control group. The control group received the standard rehabilitation treatment offered in the clinic. In addition to the standard rehabilitation program, the intervention group conducted supervised exergame training on 5 days per week using the Dividat Senso, an exergame system specifically designed for older adults. The primary outcome was feasibility, as measured by e.g., adherence rate, attrition rate, occurrence of adverse events, System Usability Scale (SUS) and NASA-TLX score. Secondary outcomes included measures of physical and cognitive functioning such as comfortable walking speed, maximal walking speed, dual task walking speed, Short Physical Performance Battery (SPPB), Timed Up and Go test (TUG), Color-Word Interference test (D-KEFS), Trail Making test A and B (TMT), Go/No-Go test and Step Reaction Time test (SRTT). All secondary outcome measures were assessed pre- and post-intervention.Results: Thirty-nine persons were included in the study. Average adherence rate was 99%, there were no intervention-related dropouts and no adverse events. The mean System Usability Scale (SUS) score was 83.6 and the mean NASA-TLX score 45.5. Significant time-group interaction effects were found for the dual task walking speed, the Go/No-Go test and Step Reaction Time test (SRTT).Conclusion: Exergaming is a feasible, safe and effective cognitive-motor training approach in inpatient rehabilitation of geriatric patients. Incorporating exergaming in the rehabilitation program of geriatric patients offers potential to reduce fall risk factors and to increase patients’ exercise motivation and rehabilitation success.

“…Moreover, engaging in PA through HBs offers numerous advantages from various perspectives. The design of the three-wheeled HB ensures safety, particularly for individuals with compromised balance and motor control, such as the elderly [17][18][19][20]. Furthermore, it fosters inclusivity by enabling individuals with specific residual abilities to actively participate in PA.…”

This study examines four tracks (Ts) suitable for handbikes (HBs) in the urban area of Brescia, Italy. WHO physical activity (PA) recommendations challenge kinesiologists to find opportunities to promote exercise in the urban context using HBs. This study aims to characterize T features, assess the physical demands of HB cycling, and promote the use of HBs. Track length, elevation changes, slope, and ascent sections were analyzed. Participants’ physiological engagement during HB cycling was measured. The data were gathered using specialized equipment including a metabolimeter, a power meter, a heart rate monitor, and a cycle computer. Crucially, the findings demonstrate that all four Ts facilitate PA above the recommended threshold (>3 MET) regardless of the speed. The study identifies specific speeds required to achieve vigorous PA (>6 MET) on each T. In summary, this study’s analysis of various tracks reveals their potential to meet PA guidelines, even at a slow pace. Moreover, this research establishes speed thresholds for vigorous PA. This information is valuable for both able-bodied individuals and those with mobility challenges when planning effective exercise routines. Moreover, the findings support municipalities in promoting adapted PA in urban areas, enhancing path usability.
