“…The sit-to-stand-to-sit and walking are good examples of this type of task (de Souza et al, 2011;Dehail et al, 2007;Galli et al, 2008;Hase et al, 2004) since they involve the coordination of joints along the kinematic chain to keep the centre of mass within the safe limits of the body's base of support (Freitas et al, 2009;Jacobs, 1997;Kiemel et al, 2008;Morasso et al, 1999;Nicholas et al, 1998;van der Kooij et al, 1999). Additionally, the lower limbs must be coordinated to provide support and stability (Sousa et al, 2013b), being recognised by the central nervous system as one functional unit.…”

“…Furthermore, with age, knee extensor strength decreases [34], and a common compensatory pattern to transition to standing is to increase lumbar flexion [35]. Thus, it is not surprising that if flexion is limited, as is the case in those with CLBP, an older adult may require more time to transition from sit to stand.…”

Objective. To explore potential differences in lumbar mobility between older adults with and without chronic low back pain, and to determine if lumbar mobility contributes to physical performance in both groups. We hypothesized that older adults with pain would have greater lumbar mobility impairments than pain-free peers, and that lumbar mobility would be associated with performance in both groups, with stronger relationships among those with pain.Design. Matched case-control.Setting. Research laboratory.Patients. Community-dwelling older adults, aged 60-85 years, with (N 5 54) and without (N 5 54) chronic low back pain.Methods. Inclinometer-measured maximal angles of lumbar flexion, extension, and average sidebending, as well as time to complete performance measures, Repeated Chair Rise and Timed-Up-andGo, were measured in both groups. Analysis of variance was used to explore the difference in lumbar mobility between groups. Adjusted linear regression was used to assess the independent relationship between lumbar mobility and physical function in both groups.Results. Those with pain had smaller angles of flexion (P 5 0.029) and extension (P 5 0.013). In the pain group, flexion explained 19% (P 5 0.001) and 8.9% (P 5 0.006) of the variance for time to complete the Repeated Chair Rise and Timed Up-and-Go tests, respectively. In the pain-free group, extension explained 12.7% (P 5 0.007) and 10.3% (P 5 0.008) of the variance for time to complete Repeated Chair Rise and Timed Up-and-Go tests, respectively.Conclusion. Older adults with chronic low back pain have more lumbar mobility impairments. Lumbar mobility may be a contributing factor to decreased performance in older adults. Flexion may be most important to performance in those with pain, while extension may be vital in those without pain.

“…The pattern and definition of the STS activity have been analyzed by many authors [5,19,22,28] based on the observation and measurements of body markers. Aissaoui and Dansereau [1] present a detailed description of the STS cycle, based on the detection of events that separates the cycle into phases (see Fig.…”

This study introduces the concept design and analysis of a robotic system for the assistance and rehabilitation of disabled people. Based on the statistical data of the most common types of disabilities in Spain and other industrialized countries, the different tasks that the device must be able to perform have been determined. In this study, different robots for rehabilitation and assistance previously introduced have been reviewed. This survey is focused on those robots that assist with gait, balance and standing up. The structure of the ROAD robot presents various advantages over these robots, we discuss some of them. The performance of the proposed architecture is analyzed when it performs the sit to stand activity.
