Computerised automated feedback systems for sit-to-stand training
The ability to stand-up from sitting declines with age. Manual rehabilitation services are being challenged by the increasingly older frailer population with patients are receiving sub-optimal access to professional therapy. Technology may offer solutions. Following a review of the literature as …

Activity segmentation with special emphasis on sit-to-stand analysis
In this study, we present algorithms to segment the activities of sitting and standing, and identify the regions of sit-to-stand transitions in a given image sequence. As a means of fall risk assessment, we propose methods to measure sit-to-stand time using the three dimensional modeling of a human …

The Biomechanics of Sit-to-Stand and Physical Performance in Patellofemoral Osteoarthritis
… of males with knee pain. Biomechanical factors such as tibiofemoral alignment and high joint stress are associated with the development and progression of PFOA. PF joint stress is high when the quadriceps contracts with the knee in a position of extreme flexion, such as rising from sitting. …

Modeling the Sit-to-Stand Transition using Koopman Lifting Linearization and Human State Estimation
The Sit-to-Stand (STS) transition is one of the most dangerous daily activities for the elderly population, as it is one of the situations in which falls occur most often. Despite its risks, STS dynamics remain poorly understood, and current STS assistance devices fail to utilize knowledge of STS …

Temporal and spatial muscle synergy features and its neural origins during sit-to-stand and stand-to-sit tasks
Sit-to-stand (STS) and stand-to-sit (StandTS) play a vital role in our daily lives. These two transitional motions are considered crucial for independent living. Many people with neurological disorders that lack neuromuscular control lose the ability to perform the transition tasks normally. …

Effect of prosthetic alignment on muscle activity for people with a unilateral transtibial amputation during sit-to-stand, The
… motion strategies during daily tasks compared to people without an amputation. These altered motion strategies can result in the development of secondary conditions, such as residual limb or low back pain, but the underlying muscle activity that causes altered motion strategies, and potentially …

The effect of focus of attention on motor performance and learning during a sit to stand task in individuals post acute stroke
Individuals post stroke have reduced ability to stand up with symmetrical weight bearing, while maintaining a midline trunk position. The reduction in the ability to stand up can affect their independence, fall risk, and quality of life. Rehabilitation and the type of instruction provided can …

AGING-RELATED DECREMENTS DURING THE ACTIVITIES OF THE TIMED UP AND GO TEST WHEN COMBINED WITH MOTOR TASK AND VISUAL STIMULATION
… and proprioceptive sensory information can lead to balance loss and falls. In addition to increased visual dependence (VD), older adults have more difficulty than younger adults in multi-tasking, performing simultaneous tasks (e.g. walk and talk), which may further increase fall risk. A common …

Determination of the Functional Relationship Between Lumbar Lordosis and Pelvic Tilt
… During SFS it is difficult for the surgeon to properly align the spine’s s-shape, as viewed from the patient’s side. Abnormal alignment of the spine then alters the position of the pelvis and hip joints, which may impact the function and hip contact patterns. Several studies have shown that …

Exploration of Movement Variability and Limb Loading Asymmetry During Simulated Daily Functional Tasks
… a complicated dynamic system that is difficult to model because of the numerous interactions that occur between limbs during various tasks. There are documented movement differences when assessing movement in various populations, for example, joint angle and loading symmetry differences when …

A Comparative Study on the Effects of Eccentric Flywheel Overload and Traditional Resistance Training on the Physiological/Functional Performance in Healthy Older Adults
… declines in muscle strength, muscle mass, motor unit activation, muscle power and functional performance. Two strength training methods (Traditional resistance training and Eccentric flywheel overload training) have been suggested as effective means of combating these age-related declines and …

The auto assist bar system for disabled people
This paper presents the development of the auto assist bar system to help the disabled people especially paralyzed in the legs where they have a problem to doing transaction stand-to-sit and sit-to-stand. An example the difficult movement of people with disabilities are from wheelchair to bed or …

Variability of centre of mass velocity through stroke recovery
… of centre of mass (COM) velocity during the sit-to-stand movement in recovering stroke patients. Patients were assessed at baseline- directly after stroke, outcome- after 6 weeks of therapy and follow up - after 12 weeks of therapy. It was expected that inter-trial variability would decrease …

A randomised control trial for the restoration of functional ability in patients post total knee arthroplasty: a comparison of eccentric versus concentric cycling ergometry
Purpose: The predominant impairment to function following a total knee arthroplasty (TKA) is a distinctive reduction in quadriceps muscle strength. It has been suggested that eccentric rehabilitation may be more beneficial than traditional concentric only rehabilitation at improving muscle …

A randomised controlled feasibility trial to investigate the effects of a functional standing frame programme versus usual physiotherapy to improve function and quality of life and reduce neuromuscular impairment in people with severe sub-acute stroke
… therefore, the effects of undertaking prolonged standing and sit to stand repetitions (functional standing frame programme) early after severe stroke during inpatient sub-acute rehabilitation is unknown. Methods A systematic review of non-pharmacological interventions to treat OH in people with …

The Impact of Lower Limb Dominance on Side-to-Side Symmetry in Daily Living and Sports-related Tasks
Evaluating side-to-side symmetry in the lower extremity has been significant in assessing injury risk and the success of rehabilitation programs. Considering limb dominance in the lower limbs is also important as limb dominance could influence symmetry measures. There is a need to assess symmetry, …
