This study systematically analyses the effects on performance (effectiveness and efficiency) as well as experience (satisfaction) when using a Posture Assistance Device (PAD). Therefore an evaluation of the presented PAD was made by a multiple measurement approach in laboratory setting. In a within subject design two tasks were performed in two conditions with and without PAD. The results show advantages of the PAD regarding all criteria. Objective measurement by sEMG showed a reduction of the electrical activity of the analyzed trapezius and delta muscle when using the PAD (human efficiency). Furthermore the results show that the usage of the PAD improves the performance by decreasing the time (use efficiency) and errors (effectiveness) in both tasks. The ratings of the subjects show a satisfied attitude towards the PAD, too.
Comparação da oscilação postural estática na posição sentada entre jovens e idosos saudáveis
Revista Brasileira de Fisioterapia, 2009
Objectives: To describe a new method to analyze the static sitting postural sway and to compare the results of healthy young and older adult subjects. Methods: Thirty-eight healthy subjects took part in the study, including 17 young adults (mean age 23±2.38 years old) and 21 older adults (mean age 67±2.42 years old). The device used to quantify trunk sway was the magnetic field sensor Polhemus ® 3Space Isotrack II. The measurements were taken in the eyes-opened (EO) and eyes-closed (EC) condition with the subjects seated first on a wooden stable surface (SS) then on a foam unstable surface (US) without back or foot support. Each sensory condition was assessed for 90 seconds. The analyzed parameters were: maximum amplitude (Amp), total trajectory (Traj) and mean velocity (Vel) in the sagittal (X) and frontal (Y) planes. Results: In the EO and EC conditions on SS, young adults presented greater postural sway in the X and Y planes on the Traj and Vel parameters. In the US, young adults showed greater Y Traj and Y Vel in the EO and EC conditions, and there was no significant difference between the groups with regard to X Traj and X Vel in the EC condition. The young adults presented greater Amp only in the EOSS condition in the X plane. Conclusions: The young adult subjects presented greater sway in the sitting position than the older adult subjects. In addition, the Polhemus ® device was a useful tool to analyze static sitting postural sway and can be used in future studies that associate static sitting postural sway with the effect of various motor tasks.
An Evaluation of Sit to Stand Devices for Use in Rehabilitation
Advances in Intelligent Systems and Computing
There are many assistive devices to help with raising a person from a seat. These devices are considered active as they require some balance, trunk control and weightbearing ability. There is concern that this movement is mostly passive due to fixation at the trunk and knee. This study explores the movement patterns in sit to stand transfers active and assisted. Study Design: A fully squared repeated measures design was use. All participants (n = 20) used all conditions (n = 7) in a balanced order. Transfers were recorded with; video recordings, a 6 dimensional force plate, hip, knee and ankle positions were recorded with motion capture. Subjective evaluations for comfort and security were completed. Physical data was compared with ANOVA calculations with Bonferroni corrections. Results: Device G scored highest for comfort, knee support and overall preference. Sling movement had a negative effect on the sensations of comfort and security. The motion analysis of the flexible knee support showed: • People push into the floor and CoP moved towards the toe. • More anterior knee movement (P < 0.05). • More bodyweight through feet (P < 0.05). • Quicker transfer of weight onto feet. • Very low bodyweight was recorded in all lowering actions. The use of a flexible knee support raised the subjective and physical performance of the assistive device and may improve rehabilitation responses.
Commercial Postural Devices: A Review
Sensors
Wearables are devices worn on the human body and are able to measure various health parameters, such as physical activity, energy expenditure and gait. With the advancement of technology, the general population are now spending more hours craning our necks and slouching over smartphones, tablets and computers, et cetera. Bodily posture is representative of physical and mental health. Poor posture can lead to spinal complications and the same can be said vice versa. As the standard of living increases, there is an increase in consumerism and the expectation to maintain such a lifestyle even in the aging population. Therefore, many are able to afford small luxuries in life, such as a piece of technology that could potentially improve their health in the long run. Wearable technology is a promising alternative to laboratory systems for movement and posture analysis. This article reviews commercial wearable devices with a focus on postural analysis. The clinical applicability of posture...

Falls are common during aging, and can have drastic consequences. Within this context, maintaining the ability to balance plays an essential role in enabling older adults to continue to perform their daily activities. Therefore, the use of interventional and treatment tools for development of balance becomes essential. The objective of this study was to analyze the anchor system as a potential tool for decreasing body sway in older and young adults. Older adults had more postural sway than their young counterparts. The absence of visual information led to larger instability in both groups. The anchor system improved postural stability of both groups. Thus, it may be a useful tool for posture stabilization in old and young adults.
Development and initial validation of the Seated Posture Scale
Journal of rehabilitation research and development, 2015
Literature shows that some health outcomes (e.g., eating, breathing, and speaking) are directly related to posture. Evidence of outcomes mediated by wheelchair seated posture is limited to interface pressure, physical function, and wheelchair skills and safety. This study's purpose was to develop and validate a rapid, low-burden, paper-pencil assessment of wheelchair seated posture for research use and to test feasibility of its use with a sample of older adults. We used a prospective design and a convenience sample of older adults who were receiving rehabilitation services in a community living center. Forty-nine older wheelchair users participated. Main measures were the Seated Posture Scale (SPS), Modified Ashworth Scale, Barthel Index, Visual Descriptor Scale, scale-content validity index (S-CVI), Cronbach alpha, and test-retest reliability. Rating by six experts yielded the overall content validity score (S-CVI) of 0.744. Total SPS score correlated positively with physical ...

An incorrect posture can generate stress of the spine and can be the cause of musculoskeletal disorders. Considering the extensive use of the computer, which worsens posture disorders, among workers, is important to analyze the phenomenon in order to reduce his impact on industry. The aim of this study is to assess determinants regarding posture in a large population of a metropolitan area. A total of 1177 questionnaires was analyzed. The majority of sample showed good knowledge and attitude regarding correct posture; most of the sample, 70.4% was aware of the definition of posture and 68.7% feel that not enough attention is paid at posture at workplace. Despite the good predisposition, only 2.8% of the sample consult a specialist for posture. The multiple linear regression analysis shows that those who have higher knowledge and best attitudes will consequently have good behaviors in maintaining a correct posture. Furthermore, age and education resulted main drivers of correct postu...

The central nervous system (CNS) utilizes anticipatory (APAs) and compensatory (CPAs) postural adjustments to maintain equilibrium while standing. It is known that these postural adjustments involve displacements of the center of mass (COM) and center of pressure (COP). The purpose of the study was to investigate the relationship between APAs and CPAs from a kinetic and kinematic perspective. Eight subjects were exposed to external predictable and unpredictable perturbations induced at the shoulder level while standing. Kinematic and kinetic data were recorded and analyzed during the time duration typical for anticipatory and compensatory postural adjustments. When the perturbations were unpredictable, the COM and COP displacements were larger compared to predictable conditions with APAs. Thus, the peak of COM displacement, after the pendulum impact, in the posterior direction reached 28 ± 9.6 mm in the unpredictable conditions with no APAs whereas it was 1.6 times smaller, reaching 17 ± 5.5 mm during predictable perturbations. Similarly, after the impact, the peak of COP displacement in the posterior direction was 60 ± 14 mm for unpredictable conditions and 28 ± 3.6 mm for predictable conditions. Finally, the times of the peak COM and COP displacements were similar in the predictable and unpredictable conditions. This outcome provides additional knowledge about how body balance is controlled in presence and in absence of information about the forthcoming perturbation. Moreover, it suggests that control of posture could be enhanced by better utilization of APAs and such an approach could be considered as a valuable modality in the rehabilitation of individuals with balance impairment.
Arm Movements Effects in Response to Posture Instability
2021
In recent years, because of an increasing aging population there are higher incidences of falling according to epidemiological reports. Because of this high frequency the prevention of falls becomes a major concern. Evidence of the high occurrence and significant cost of falls on health-related quality of life, significant financial load on the health care system, and on their social impact has been provided by various epidemiological studies. Falls are the second leading cause of traumatic brain injury (TBI), which is a major cause of death in many countries, especially the United States. Balance impairments are frequent and particularly high among people who suffer from stroke, TBI, incomplete spinal cord injuries, Parkinson’s disease, multiple sclerosis and diabetic peripheral neuropathy, and in general for people who suffer from different neurological disorders. For all of these groups, balance disorders have a major social and quality of life implications, which require attenti...
