“…Other studies have focused on partial weight-bearing gait while using conventional assistive devices [17], the stability and maneuverability of wheeled walking frames [18], and the impedance of lateral compensatory stepping movements by canes and walkers [19]. Therefore, we conclude that walkers absorb the vertical and lateral movements of the entire body during walking, while the inertial force of the walker wheels regulate the step width.…”

Walkers improve self-reliability. We examined the effectiveness of a newly developed wheeled walking frame for use by physically handicapped persons. Unstable gaits in walker users were analyzed by tri-axial accelerometers and a motion capture system. Several markers were placed on subjects' backs and legs. Subjects were requested to walk around a test course at a comfortable speed, while their motion was recorded by two high-speed video cameras. The activities performed on the test course comprised standing, normal walking, fast walking, and walking over a barrier. Any accidental falls were also recorded. We established the characteristic rules of gait motion using a walker. Furthermore, we demonstrated that gait characteristics are more conveniently extracted from acceleration sensors than from motion capture systems, since the sensors can be affixed to subjects for self-monitoring and goal achievements. The methods employing acceleration sensors are considered suitable for determining the average gait motions of elderly persons living in nursing homes, and can be used to evaluate walking motion before and after rehabilitation.

Abstract-Assistance to people during rehabilitation has to be adapted to their needs. Too little help can lead to frustration and stress in the user; an excess of help may lead to low participation and loss of residual skills. Robotic rollators may adapt assistance. The main challenge to cope with this issue is to estimate how much help is needed on the fly, because it depends not only on the person condition, but also on the specific situation that they are negotiating. Clinical scales provide a global condition based estimation, but no local estimator based on punctual needs. Condition also changes in time, so clinical scales need to be recalculated again and again. In this paper we propose a novel approach to estimate users' condition in a continuous way via a robotic rollator. Our work focuses on predicting the value of the well known Tinetti Mobility test from spatiotemporal gait parameters obtained from our platform while users walk. This prediction provides continuous insight on the condition of the user and could be used to modify the amount of help provided. The proposed method has been validated with 19 volunteers at a local hospital that use a rollator for rehabilitation. All volunteers presented some physical or mental disabilities. Our results sucessfully show a high correlation of spatiotemporal gait parameters with Tinetti Mobility test gait (R2 = 0.7) and Tinetti Mobility test balance (R2 = 0.6).

“…The use of a cane for ambulation can be encouraged as 25% of the body weight can be offloaded from the lower extremity by using this device. 97 Individuals that present with pain when ambulating are offered shoe wear modifications and bracing that attempt to decrease joint forces at the ankle. A rocker sole and solid-ankle cushion-heel (SACH) were found to decrease ankle motion and aid in the transition from heel strike to push-off during level walking.…”

T he purpose of this manuscript is to provide current information regarding the examination, conservative treatment, and surgical treatment for individuals with posttraumatic arthritis. The 3 major categories of arthritis are inflammatory, osteoarthritis, and posttraumatic arthritis. Rheumatoid arthritis is the most common form of inflammatory arthritis; however, it does not always affect the ankle.35 It has been reported that 10% to 50% of individuals with rheumatoid arthritis have ankle involvement. 8,16,48,60,83 The mechanical properties of the tibiotalar articular cartilage make it durable and efficient at equalizing stress. These properties may reduce the risk of osteoarthritis at the ankle. 7,37,75,77,80,86 Posttraumatic arthritis is more common than osteoarthritis at the ankle. Saltzman et al 71 reported that osteoarthritis and posttraumatic arthritis accounted for 12% and 70% of ankle arthritis cases, respectively.
