Filter by:The overall objective of this study is to investigate the effect of attention control training on reach-grasp stabilizing responses during fall-induced perturbations. The central hypothesis is that training attention control during reach to grasp balance perturbations will lead to increased grasp accuracies and reduced in-task falls. This research will mark the first explore the effects of training attention control on protective arm responses and fall rate during a balance perturbation paradigm and the first feasibility testing of a fully integrated cognitive and physical rehabilitation paradigm, moving beyond correlative designs and parallel treatments. The overall public health significance of the proposed research is that with improved protective arm responses and grasp accuracies, a larger randomized control study may be designed to mitigate falls among community dwelling older adults. Participants will be involved in 6 sessions. Session 1 will include the assessment, questionnaires, and training. Session 2 will include just the training. Session 3 will include the assessment and training. Sessions 4-5 will include just the training. Session 6 will include the assessment, questionnaires, and training.
The investigators aim to establish a clinical database and biobank for elderly patients with multiple diseases. The collected data will include demographic information, comorbidity characteristic, FRAIL scale, age-adjusted Charlson comorbidity index, relevant blood tests, the results of imaging examination, prescription of drugs, length of hospital stay, number of overall rehospitalizations and death. With this database, the investigators intend to formulate an individualized treatment strategy for these patients.
The aim is to evaluate the effectiveness of the device (emergency kit and video-medical control in emergency call centers) in reducing deep night hospitalizations of elderly people living in retirement homes.

This study aims to address critical knowledge gaps by investigating the effects of trait conscious movement processing propensity on real-time (state) conscious movement processing propensity, postural stability, and muscle efficiency in older adults at risk of falling in Hong Kong with high and low trait conscious movement processing propensities, while standing in a challenging environment with different levels of standing task difficulties. The study results would contribute to our scientific understanding of the mechanisms of conscious movement processing in older adults while maintaining standing balance in a challenging environment. It could inform the follow-up investigations for the development of the most appropriate psychomotor standing balance re-education intervention in rehabilitation so as to mitigate the effect of conscious movement processing and the risk of falling in older adults. The findings from the proposed research could ultimately help improve the outcome of fall rehabilitation programmes and reduce the impact of falls in the older adults in Hong Kong.
Sarcopenia has now been officially recognized as a muscle disease related to aging, which may increase the risk of falls and fractures and both heart and respiratory diseases in the elderly. Sarcopenia causes inconvenience in the elderly, affecting their quality of life and often requiring long-term care or even resulting in death. Moreover, the elderly often encountered malnutrition due to inadequate nutrient intake and scarce nutrient diversity. Furthermore, malnutrition is often one of the leading causes of sarcopenia. Therefore, effective nutritional supplementation is essential to improve or prevent muscle loss for the elderly. Cordyceps sinensis is a well-known valuable traditional Chinese medicine and Hirsutella sinensis was an asexual strain of Cordyceps sinensis. Researchers have found that Hirsutella sinensis can help to increase connection between gastrocnemius muscle fibers and spinal nerve under the amyotrophic lateral sclerosis animal disease model. However, culturing conditions for Hirsutella sinensis are extremely difficult and long, one of the key culturing condition is the temperature, must be maintaining at 16-20℃for 45 days. Fortunately, Grape King Biotech has core technology using liquid fermentation which greatly shortened the cultivation time, thus, providing sufficient and safe products to patients. The investigators designed a randomized placebo-controlled study first to investigate the relationship and clinical impact Hirsutella Sinensis had on muscle mass and function in the elderly. Second, investigate the metabolic impact Hirsutella Sinensis had on muscle mass.
This is a randomized, open-label, multicenter study to compare the efficacy and safety of AZA with or without ATRA in newly diagnosed unfit AML or Intermediate,High or Very High Risk MDS
Studies have determined that compared to cognitively intact older adults (CIOA), older adults with mild cognitive impairment (OAwMCI) exhibit more pronounced balance and gait impairments which lead to an increased risk of falls and mobility decline. Such impairments are evident during dual-tasking (i.e., simultaneous performance of cognitive and motor task) and OAwMCI have demonstrated an increased cognitive-motor interference (deteriorated performance of either or both cognitive/motor task). Furthermore, our preliminary laboratory findings indicate that compared to CIOA, OAwMCI in response to large-magnitude treadmill perturbations exhibits poor reactive responses (first line of defense against balance loss) and are unable to modulate their responses as the magnitude of perturbation increases. Despite that conventional exercise methods offer beneficial effects; they comprise of self-initiated task-specific exercises and may not focus on training reactive responses. Additionally, due to the presence of subtle balance and gait deficits, clinical measures used may not be sensitive enough to determine the risk of fall post-training. Furthermore, these training methods incorporate multiple sessions due to which adherence to exercise training is difficult with only a fraction of the older adults benefiting from it. Therefore, it is essential to incorporate a task-specific strategy that promotes factors associated with falling like balance control, muscular responses, coordination of limbs, and cognition through which OAwMCI may acquire maximum benefits to prevent a balance loss. One feasible method, which harnesses technology that can be used to deliver balance disturbances either while standing or walking in a consistent and controlled manner, is via a custom-based motorized treadmill. The scientific rigor from preliminary studies has reported a successful reduction of falls through a single session exposing CIOA to multiple treadmill-induced perturbations during gait and has shown significant improvement in reactive responses. For that reason, this stage 1 pilot study will examine the feasibility, applicability, and tolerability of a combined cognitive, and perturbation training on biomechanical determinants associated with falls and promote physical activity: kinematic variables, muscular responses, and cognitive function.
Current balance and stability interventions have been shown to improve balance through targeting balance impairments and retraining effects. However, there are key facilitators and barriers 'that older adults may face to participate in such interventions'. Additionally, physical activity interventions fail to integrate older adults into the co-design and co-production of PA interventions. The study will aim to identify the impact and practicalities of an exercise intervention in older adults by performing pre selected exercises with an elastic resistance band attached at the hip and chest region to challenge balance. Researcher led interviews will focus on the participants perceptions of the activities and decision making of exercise selection by selecting components that they are confident to perform which is a key element to creating a practical and enjoyable exercise programme for the older population. This will co-create an intervention that is accessible, acceptable, and appropriate for older adults. The study will establish the accessibility, acceptability and appropriateness of an elastic band exercise intervention with older adults by performing selected activities followed by researcher led interviews that will focus on the participants influences, perceptions and psycho-social factors related the intervention activities.
An aging society is known as having at least 7% of its population aged 65 and older, whereas 14% or more known to be an aged nation. Age has a detrimental effect on the physical performance and the muscle strength, the reduced muscle strength, mass and structure in the elderly are due to aging, disuse and inactivity. In the elderly, the reduction of muscle strength is faster than the associated loss of muscle mass. The maximum isometric strength of knee extensors and muscle mass decrease due to aging. The combination of quadriceps and handgrip strength weakness in the elderly is associated with the poorest scores on quality of life, GP contact-time, gait speed, hospitalization and disability in daily living. Quadriceps weakness among elderly is also proved to be a contributing factor to fall among frail nursing home residents. A systematic review and meta-analysis revealed that quadriceps muscle weakness was associated with greater risk of developing knee osteoarthritis during 2.5 to 14 year follow-up in either gender. In overall, aging cause reduce muscle strength, especially quadriceps muscle, can cause many others negative consequences, thus a study of effect motor imagery on quadriceps muscle strength in community-dwelling elderly should be carried out, if this study is proven to effectively, motor imagery technique can be widely utilized on bedridden elderly or elderly who have severe cardiovascular disease who unable to perform physical activity to maintain or improve their muscle strength.
