Filter by:This study aims to provide a novel scientific contribution through addressing critical knowledge gaps, examining the effects of attentional focus instructions on real-time (state) conscious movement processing propensity, gait parameters, and muscle efficiency in older adults in Hong Kong at risk of falling while walking in a challenging environment. The study results could update our scientific understanding of the mechanisms of conscious movement processing and the interventional effects of attentional focus instructions in older adults. It could ultimately enhance the methodology used for developing the most appropriate psychomotor gait re-education intervention in rehabilitation and provide clear guidelines on the exact attentional focus training that older adults require. Further, it could mitigate the effect of conscious movement processing and risk of falling in older adults.
Sarcopenia is quickly becoming a major global public health issue. Falls are the leading cause of mortality among the elderly, and they must be addressed. The investigators will use machine learning techniques such as empirical mode decomposition technology and decision tree algorithms to extract the characteristics and classification of sarcopenia in this retrospective study in order to offer clinically proven and effective interventional strategies to prevent, stabilize, and reverse sarcopenia.
A fall in the elderly is defined by the WHO as "an event in which a person [over 65 years of age] inadvertently falls to a lower level on the ground or other surface than they were previously at". The severity of the consequences of falls is correlated with the age of the person who suffers them, making people over 65 at risk. Since 2000, the number of falls among the elderly has not decreased, including in institutions. Today, the direct and indirect costs of falls are estimated at 1.7 billion euros in France. The French National Authority for Health (HAS) stresses that the lack of success of prevention policies is due in particular to the lack of evaluation and prevention resources. In nursing homes, this lack of resources is sometimes used to justify passive restraint to ensure the safety of participants. However, this method poses the problem of the free movement of residents within the institution. The fall detection technologies already on the market do not allow for the assessment of the risk of falling and therefore for early action. Based on the latest scientific data in static posturography, researchers at the Borelli Centre have developed posturographic markers whose non-linear analysis makes it possible to establish an objective and clinically relevant score based on the study of the displacement of the centre of pressure. In contrast to the techniques commonly used in the laboratory to study balance (which are not usable in health care institutions because of their cost, lack of transportability and the expertise required to explore the recorded data), this method of measurement allows health care professionals to quickly and easily measure the balance of participants in routine consultations. Thus, special attention and targeted rehabilitation can then be implemented to prevent falls and their consequences.
ZeroG is an FDA-listed robotic body weight support system (BWSS). Mounted on an overhead track, patients are fitted in a harness system tethered to said track, and are able to practice gait and balance activities without the risk of falling. This compensates for ineffective postural control permitting intensive therapy sessions earlier in recovery. The purpose of this study is to determine if inducing effective and safe balance perturbations during standing and walking in the BWSS more effectively improve postural control than the BWSS without perturbations. The target population are those patients in the post-acute phase of stroke admitted for inpatient rehabilitation of balance impairments. Site investigators and/or research staff will obtain names of potential subjects from internal reporting identifying inpatients who may qualify for the study based on the inclusion criteria. Trained site investigators will meet with potential subjects to explain the study, complete a screening interview for exclusion and inclusion criteria, answer any questions, obtain informed consent and HIPAA authorization, and schedule the study therapy sessions involving the protocol. Based on the randomization scheme provided by the lead site, consented subjects will be randomized to either the BWSS with perturbations (BWSS-P) or standard BWSS control without perturbations. Subjects will perform 2 to 6 sessions in their designated intervention using a structured protocol for each session. To compare differences between treatment groups, outcome measures will be collected at baseline before any BWSS sessions are performed and within 48 hours after completing the final treatment session.
Vertebral column fracture presents a significant warning of subsequent osteoporotic fracture and frequent falls. The presence of an osteoporotic vertebral fracture is also a predictor of further risk of vertebral and other osteoporotic fractures. This study provides balance assessment and gait evaluation for subjects with a known vertebral fracture. Subjects are the known cases of vertebral fracture living in the community. They will be assessed for their balance and gait weight distribution by the TechnoBody for their balance ability, and the Zebris Gait System for the gait weight distribution.

Parkinson's disease (PD) related gait and balance disorders are challenging to treat because they cannot be optimized with pharmacological intervention alone. This treatment gap is important to address because gait asymmetry and incoordination are associated with increased falls in this population, which can be functionally debilitating and lead to increased morbidity and mortality. Freezing of gait (FOG) has also been associated with reduced quality of life independent of its association with impaired mobility. Gait disorders therefore represent an unmet need in the treatment of PD. A split-belt treadmill (SB-TM) can be used to adjust the speed of each leg separately and individuals can be prompted to 'adapt' to an asymmetric gait and 're-adapt' with return to symmetrical gait in a phenomenon known as 'after-effect'.
This cross-sectional study aims to investigate the prevalence of post-stroke visual dependence, and the effects of visual dependence on balance and gait. It also determines whether visual dependence could differentiate stroke patients with a history of falls from without.
It has been shown that movements of the upper extremity during walking are associated with lower extremity mobility. For example, when walking at a slow pace, the swing frequency of the arms is 2: 1 compared to the legs, while the limb frequency decreases to 1: 1 as the walking speed increases. That is, in order to walk fast, the lower extremity takes advantage of the acceleration of the upper extremity [1]. It is known that the muscles of the shoulder girdle also support this oscillating movement in the upper extremity during walking. Thus, it is thought that blocking or restricting shoulder girdle and arm movements during walking increases energy expenditure and heart rate, decreases gait stability, and decreases stride length and walking speed [2,3]. However, the possible effects that the upper limb can aid in movement include decreasing vertical displacement of the center of mass, decreasing angular momentum or decreasing ground reaction moment, and increasing walking stability [2-4]. In these studies that restrict arm swing, methods such as crossing the arms on the chest [5], holding the arm in a sling or pocket [6], or fixing the arms to the trunk with a bandage [7] were used. Studies have generally been conducted on healthy individuals or on the biomechanical model, and arm swing during walking has not been investigated in pathologies with only upper extremity involvement (upper extremity fractures, Juvenile Idiopathic Arthritis) without any problems with lower extremity and/or walking. This study is aimed to reveal the effects of decreased upper extremity functionality on walking and balance.
To explore the feasibility of a novel ballet-inspired low-impact at-home workout programme for community-dwelling stroke survivors in Hong Kong.
The main hypothesis of the present study is that a safer knee joint is likely to encourage post stroke patients at an early stage to rely on their hemiparetic leg and transfer their weight onto it while walking. The main purpose of the present work is to assess the feasibility of FES-induced muscular control of the hemiplegic knee joint in order to improve stance phase support symmetry recovery in individuals with post stroke hemiplegia. Functional electrical stimulation (FES) is delivered to the quadriceps and hamstrings of the paretic limb based on the real-time estimation of the knee angle and support phase.
