“…Fatigue due to STS exercise may have therefore been primarily accumulated in musculature that control sagittal body sway such as ankle plantar-flexor and knee extensor musculature (Barbieri et al, 2013), whereas medial-lateral sway controlled predominately by hip and trunk musculature through a loading/unloading strategy may have been affected to a lesser extent (Shummway-Cook & Woollacott, 1995;Winter, 1996). It has been previously shown that STS movement requires significantly higher levels of KE efforts compared to that at the ankle and hip (Bieryla et al, 2009;Burnfield et al, 2012), and it is possible that increased COPy sway velocities during LOS testing immediately after repetitive STS exercise may be attributable to greater accumulation of fatigue in KE musculature (Barbieri et al, 2013). Since the control of COP position within the BOS is primarily reliant on ankle musculature (Corbeil et al, 2001;Doorenbosch et al, 1994) the amplitude of the A-P voluntary LOS may not have been affected by the STS fatigue protocol if significantly lower efforts were required by the ankle musculature compared to those at the knee.…”

“…Meanwhile, Burnfield et al compared normal and assisted movements of healthy people using STS rehabilitation devices. Although their device simulates normal transfer, they found that the assisted movement was different from that of normal movement [7]. Ruszala et al also compared four STS devices from the point of view of a physiotherapist.…”

Equipment developed for rehabilitation commonly carries patients in reference movements that are generally based on natural movements of healthy people. This type of movement may not place the lowest load on a patient's body. We propose a selecting process of an index value that quantifies the body load during sit-to-stand (STS) movement to evaluate natural movements of a person and to calculate an optimized movement about a specific part of the body for individualized rehabilitation. The computation starts by collecting kinematic and kinetic data, estimating the forces and moments, and then extracting an index value of the movement that quantifies the body load. The index value strongly correlates with the chair height, and decreasing the value of this index by changing the movement during STS transfer could reduce the impact on the body, which is the same amount of load as that placed on the body while standing up from a higher chair height. A modified STS movement that can minimize the body load is finally computed. The results of this study could be used to help users see how much force and moment are placed on the ankle, knee, and hip joints, and provide a personalized optimum movement for rehabilitation with reduced body load on patients.

“…Chuy et al [7] presented two approaches to assisting with the STS movement by using a robotic walking support system and showed that this system can track the desired support force. Rather than using kinematic data, Burnfield et al [8] compared muscle demands through electromyography during self-performed and device-assisted STS transfers.…”

Many service robots have been developed to assist patients with sit-to-stand movement (STS). However, little research has focused on users' negative psychological changes during the STS movement when assisted by a robot. The STS movement accompanied with a negative psychological change is defined as a fault. The main purpose of this study was to propose a method of conveying faults to a service robot through the center of mass (CoM). Experiments on the STS movement were executed five times with 10 healthy subjects under four conditions: two self-performed STSs with seat heights of 43 and 62 cm, and two robot-assisted STSs with a seat height of 43 cm and end-effector speeds of 2 and 5 s. Time series data on the CoM were measured with high-speed camera system. A classifier was designed according to the data on the CoM in the frequency domain. The results showed that the proposed classifier had a high probability of discriminating fault classes from others. Then, the vertical ground reaction force (vGRF) under the same experimental conditions was used to cross-check the experimental results. It was concluded that faults in the assistance of service robots can be detected from the CoPrelated items.
