Mobility Limitation

This pilot clinical trial evaluates whether non-invasive brain stimulation improves the orientation and mobility (O\&M) skills of individuals with constricted visual fields in both eyes. The study is composed of three visits. The first visit is meant to confirm eligibility by performing a few clinical tests. Eligible participants will then complete two additional visits, one in which the participants receive active stimulation, and one in which the participants receive placebo (sham) stimulation. Stimulation will be administered in a randomized, double-blind order. To evaluate improvement, various measures of O\&M performance will be assessed on a standardized obstacle course featuring static natural and artificial obstacles at defined intervals after the intervention. We hypothesize that the application of hf-tRNS to V1 will improve the orientation and mobility skills of individuals with constricted visual fields immediately following stimulation as a results of enhanced periphery through modulation of the mechanisms responsible for crowding, thereby reducing crowding effects and improving contrast for individuals with rod-cone dystrophy and RP (genetic conditions), whereas for individuals with glaucoma (a neurogenerative condition), any improvement noted would be attributed to be enhanced processing of visual signal in the affected periphery. The results will inform the design of a future, larger-scale study.

A sedentary behavior in the postoperative phase has a negative impact on recovery from various types of surgery (e.g. abdominal, pulmonary, cardiac or esophageal). In fact, sedentary behavior in the days following surgery is associated with an increased risk of postoperative complications, longer hospital stays and, consequently, higher healthcare costs. Stimulating early mobilization and increasing the level of physical activity after surgery therefore remains a relevant current challenge. The Culture Care program will propose a new experience of the hospital towards an attractive and stimulating intrahospital environment, including art and culture. The hypothesis is that the innovative, positive hospital experience offered by the Culture Care program could contribute to increasing patients' mobility in the postoperative phase and thus reduce the sedentary behaviour compared with a control group included before the implementation of the program. The aim of this study is to explore the effect of the Culture Care program (Control group versus Culture Care group) on the mobility of patients hospitalized after thoracic or abdominal surgery, by determining the level of prediction in relation to the influencing covariates reported in the literature. The first quantitative part of this research project will compare the mobility of patients hospitalized after surgery, before (control group) and after the implementation of the Culture Care program (Culture Care group). Patients will be asked to wear an accelerometer for the first five post-operative days, and to complete three questionnaires (psychological well-being, physical recovery, perception of their mobility). Healthcare workers will be asked to complete a survey on their readiness to stimulate patients' mobility before and after the Culture Care program. The second part will be qualitative including individual semi-structured interviews with patients and healthcare workers during the Culture Care program, to gather their experiences.

The goal of this clinical trial is to learn whether a powered wearable lower-limb exoskeleton can improve walking performance in independently ambulatory older adults aged 65 to 75 years. The main questions it aims to answer are: * Does use of a powered lower-limb exoskeleton increase comfortable walking speed over 10 meters? * Does use of a powered lower-limb exoskeleton increase average walking speed during a 400-meter walk? Researchers will compare walking performance in older adults during walking with the powered exoskeleton and walking without the device to determine whether the exoskeleton improves mobility. Young-adult reference participants will also complete walking assessments to provide reference values for walking performance. Participants will: * Attend a screening and familiarization visit. * Complete walking assessments with and without the powered exoskeleton in randomized order (older adults only). * Perform a 10-meter walk test, a 400-meter walk test, and other physical performance assessments. * Complete questionnaires about balance confidence, fear of falling, and device usability. * Be monitored for safety events during testing.

The investigator proposes to conduct a randomized trial of supervised ambulation delivered by mobility technician (MT) up to three times daily, including weekends, to hospitalized medical patients. The aims of the study are to compare the short and intermediate-term outcomes of patients randomized to the intervention versus those patients randomized to receive usual care, to identify patients who are most likely to benefit from the intervention and to assess whether the intervention increases or decreases overall costs of an episode of care, including the cost of the MTs, the index hospitalization and the first 30 days post enrollment.

Declines in cognitive function and walking function are highly intertwined in older adults. A therapeutic approach that combines complex (cognitively engaging) aerobic walking exercise with non-invasive electrical brain stimulation may be effective at restoring lost function. This study tests whether electrical stimulation of prefrontal brain regions is more beneficial than sham stimulation.

The incidence of hip fractures in France is 50,000 cases per year among women and 16,000 among men, with a 1-year mortality rate of 20-24%. After a fracture, 10-30% of patients become functionally dependent. The increasing aging of the population and the rise in dependency are likely to worsen the situation of older patients in hospital settings. Several tools are available to assess functional independence, including the New Mobility Score (NMS), which evaluates mobility through three domains: mobility indoors, mobility outdoors, and shopping activities. The NMS has shown good performance in predicting patient mortality and functional recovery, and its use is recommended in clinical practice. However, the French version of the NMS has not yet been validated. The French validation of the NMS is important to facilitate its implementation in clinical practice and research, particularly because of its simplicity and the need for rapid assessment tools for healthcare professionals. A French version of the NMS has been translated, and the MOB-SCORE study aims to assess its reliability and validity among healthcare professionals caring for patients with hip fractures.

This clinical study examines whether a co-designed mobility intervention can be delivered in routine hospital care after hip fracture surgery. Hip fracture is a common and serious condition among older adults and is associated with loss of independence, complications, and increased mortality. During hospitalization, many patients remain inactive, even though early and frequent mobility is considered important for recovery. The HIP-ME-UP intervention was developed in collaboration with healthcare professionals, patients, caregivers, and hospital management. It aims to support early mobilization, independence in basic mobility activities such as getting in and out of bed and increased physical activity during hospitalization. The study will investigate whether the intervention is feasible to deliver in routine clinical practice, whether it is delivered as intended, and whether it is acceptable to patients and healthcare professionals. Participants admitted after a hip fracture surgery will receive the intervention during hospitalization. Researchers will collect information on recruitment, retention, fidelity, acceptability, and mobility-related outcomes. Approximately 25 participants will be included. The results will help determine whether a larger effectiveness study should be conducted.

The goal of this study is to learn if contrast frequency on step tread-edges influences foot clearance measures, a marker of fall risk, in older adults with and without visual impairments. The main questions that aim to be answered are how foot clearance measures change across different frequencies of stair contrast, and how experiences and perceptions of different stair contrast frequencies are evaluated. Researchers will compare individuals with and without visual impairments to see if contrast frequency on step tread-edges changes. Participants will attend one visit during which their vision will be measured, and they will be asked to ascend and descend laboratory stairs at different contrast frequencies. An optional second visit will entail a focus group meeting to better understand how contrast affects mobility in their home and everyday life.

Walking speed is a powerful predictor of mortality and adverse health consequences (e.g. fall or hospitalization) in older adults. Knowledge of individuals' walking speed can provide unique insight into current physical function and need for healthcare services. Furthermore, walking speed is a modifiable risk factor such that early recognition of physical function decline allows for appropriate and timely intervention prior to the occurrence of adverse health events. Therefore, this proposal seeks to implement routine measures of walking speed into VHA primary care as a 'vital sign' to routinely monitor Veteran physical function and help guide provider referrals.

Hospital immobility leads to serious complications including muscle loss, weakness, delirium, pressure ulcers, and blood clots. Despite being medically stable, hospitalized patients spend over 90% of their time in bed due to staffing shortages, fall risks, and limited physical therapy availability. Within one week of admission, patients can lose approximately 2% of thigh muscle mass per day, and nearly half develop clinically significant hospital-acquired weakness.The Bedside Bike is a portable, low-resistance exercise device that clamps securely to hospital beds, allowing patients to perform leg and arm cycling exercises safely without leaving their bed. This study will evaluate whether hospitalized patients at Indiana University Health facilities can feasibly and safely use the Bedside Bike to maintain mobility during their hospital stay.This quality improvement study will enroll 80 adult inpatients expected to stay at least 3 days. All participants will receive the Bedside Bike in addition to usual care (standard physical therapy and medical treatment). The study will measure how often patients use the device, whether it is safe (tracking any device-related problems), and whether it may help improve outcomes such as hospital length of stay, functional mobility scores, discharge to home, and rates of hospital-acquired weakness. Participants will have functional assessments at admission and discharge, use the Bedside Bike throughout their hospitalization (targeting at least 15 minutes daily), and be followed for 60 days after discharge to track readmissions, falls, living arrangements, and mortality.

This study will evaluate the effects of combining balance training with electrical stimulation techniques in individuals with Multiple Sclerosis (MS). MS commonly impairs leg strength, coordination, and balance, increasing the risk of falls and reducing independence. The interventions include:Balance training only, Balance training with Functional Electrical Stimulation (FES), and Balance training with FES and Transcutaneous Spinal Cord Stimulation (TSCS). FES delivers small electrical pulses to leg muscles, while TSCS delivers electrical signals through the skin to stimulate the spinal cord and enhance motor control. The study will enroll up to 24 participants over a 3-year period. This trial is funded by MS Canada. Participants will be randomly assigned to one of three groups: (1) balance training only, (2) balance training with FES, or (3) balance training with FES and TSCS. All participants will complete 12 supervised training sessions over 6 weeks. During each session, participants will engage in interactive balance games while standing in a safety harness.Outcome assessments will be conducted at three time points: baseline (prior to training), post-intervention (after 6 weeks), and follow-up (8 weeks after training). Assessments will include: * Clinical tests of mobility and balance (Timed Up and Go:TUG, 10-Meter Walk Test:10MWT, Berg Balance Scale:BBS) * Computerized balance testing using a force plate * Questionnaires on walking ability, fear of falling, and balance confidence * Neurophysiological measures of brain-spinal cord-muscle communication before and after training

Choose to Move (CTM) is a 3-month, choice-based health-promoting program for low active older adults being scaled-up across British Columbia (BC), Canada. Recently, the investigators adapted CTM for the \>14000 people in BC who are on surgical waitlists for total knee replacement or total hip replacement (TKR/THR) for osteoarthritis (OA). The primary goal of this observational study is to learn if the adapted program, Choose to Move Replacement Ready (CTM-RR), is feasible to deliver to people with hip and/or knee osteoarthritis who are on surgical waitlists for TKR/THR. Participants who enrol in CTM-RR will answer online survey questions about the program and about their physical activity, mobility, pain, function, quality of life, willingness to undergo surgery, overall perception of their joint condition, psychosocial health, self-efficacy, social isolation, loneliness, and sedentary time. CTM-RR activity coaches will also answer online survey questions about the program. CTM-RR participants, activity coaches, and referral partners will also participate in interviews about the program.

This pilot, parallel-group randomized controlled trial will evaluate the feasibility, safety, usability, and preliminary efficacy of the Rise\&Walk InHome (RWH), a novel robotic gait training device designed for home use after stroke. Twenty adults with lower-extremity motor impairment following a first-ever stroke (3 months to 5 years post-event) will be randomized 1:1 to either (1) RWH-assisted home walking plus usual care or (2) usual care alone for 12 weeks. Participants in the intervention group will receive an in-home RWH device, complete a structured device training program, and be instructed to perform 30-minute RWH walking sessions four times per week (48 sessions total). All participants will undergo standardized outcome assessments at baseline, weeks 4, 8, and 12, including the 6-Minute Walk Test (primary outcome), 10-Meter Walk Test, daily step count via wearable activity tracker, and health-related quality of life (SF-36). Additional feasibility and usability outcomes include device use and adherence, patient satisfaction and motivation, ease of use, perceived exertion, and adverse events. Findings will inform the feasibility of in-home deployment of the RWH device and provide preliminary effect-size estimates to guide the design of a larger efficacy trial.

This study will examine the impact of a 10-week crossover urban park intervention on the emotional well-being of people with mobility impairments. Outcomes between 5 weeks of sensory engagement activity (i.e., enjoy sights, sounds; primarily sedentary) and 5 weeks of physical activity (i.e., wheeling/walking on trail) while in the park will be compared.

This project aims to examine the efficacy of remote, caregiver-led tES/brain stimulation intervention targeted to improve memory, mobility, and executive functioning among older adults with mild cognitive impairment or mild dementia.

The purpose of the research is to evaluate the feasibility and benefits of a six-week hybrid task-oriented resistance exercise program for older adults who have been recently discharged from home health care.

This study evaluates the feasibility and acceptability of implementing the electronic Comprehensive Geriatric Assessment (eCGA) in primary care for adults aged 65 years and older. The study examines how frailty changes over 12 months, how patient self-assessments compare with physician assessments, and how patients perceive the value of the eCGA when used as part of routine care. The study also includes an interventional randomized sub-study (PAHA), in which eligible participants receive a personalized physical activity program developed by a Clinical Exercise Physiologist. Participants are randomized to either an immediate-start or delayed-start exercise group, allowing assessment of the effects of a tailored activity intervention on frailty, physical activity participation, and goal attainment. Findings will inform how eCGA tools and personalized activity interventions can be integrated into primary care to support healthy aging and frailty management.

Endometriosis is a frequent pathology with an estimated prevalence of 10% of women of childbearing age. There is no exact correspondence between the symptoms described by the patients and the severity of the lesions, which makes clinical diagnosis difficult. It therefore seems important to improve the complementary examinations available to make the diagnosis more precise and to better study the effectiveness of the treatments implemented. The clinical examination and per-surgical findings of patients with deep pelvic endometriosis show a clear decrease in the mobility of the pelvic organs in relation to each other, but few studies have looked at this mobility, which could however have an implication in explaining the pathophysiology of the disease and the symptomatology of the patients, as well as in the detection of lesions preoperatively. The persistence of hypo-mobility could also help to understand treatment failures.

Lower extremity revascularization combined with supervised exercise significantly improves walking performance compared to revascularization alone in people who have PAD without limb threatening ischemia. However, supervised exercise is inaccessible or burdensome for most PAD patients. Investigators hypothesize that home-based exercise combined with lower extremity revascularization will significantly improve walking performance compared to revascularization alone in patients with PAD undergoing revascularization for disabling PAD. Investigators further hypothesize that inorganic nitrate, a major source of nitric oxide (NO) abundant in beetroot juice, will improve walking performance after lower extremity revascularization, compared to placebo. In preclinical models, NO inhibits inflammation, neointimal hyperplasia, thrombosis, and vascular smooth muscle cell migration at sites of revascularization. NO increases angiogenesis and perfusion, repairs skeletal muscle damaged by ischemia, and stimulates mitochondrial activity. In a randomized clinical trial with a 2 x 2 factorial design, the trial will test the following two primary hypotheses in 386 patients randomized within three months of a successful lower extremity revascularization for disabling PAD: First, that home-based exercise combined with lower extremity revascularization will improve six-minute walk distance more than revascularization alone at 6-month follow-up (Primary Aim #1). Second, that nitrate-rich beetroot juice combined with lower extremity revascularization will improve six-minute walk, compared to placebo combined with revascularization at 6-month follow-up (Primary Aim #2).

In this study, we will randomly assign 360 older adults to 12 months of 5 minutes per day of functional resistance training or to a delayed treatment control condition, and measure the impact of the training on measures of lower extremity performance and walking ability.

This study examines whether wearing a shoulder sling can improve balance and mobility in people who are recovering from a stroke. Participants will perform simple movement and balance tests twice-once with the sling and once without. The goal is to find out if using the sling helps patients feel more stable and safe during walking and everyday activities.

The purpose of this study is to develop an exercise treatment program for knee osteoarthritis that works well for people with memory problems. This study will include two parts. Participants can choose to participate in either or both parts. In Part 1 (not a clinical trial) - The investigators are inviting the following people to participate in an interview: 1. Individuals aged 60 years or older who do not live in a nursing home and have both memory issues and knee pain. 2. Care partners of people with knee pain and memory issues. A care partner can be a family member or friend who helps regularly. 3. Clinicians (exercise physiologists or rehabilitation therapists like physical and occupational therapists) who have worked with older adults with memory issues and knee pain. The goal of these interviews is to learn from the experiences of people with memory issues and knee pain and those who care for them. From these interviews, the investigators hope to design a non-drug, tailored physical activity program that will be interesting and helpful in managing knee pain for older adults with memory problems. For people with memory problems and knee pain and their care partners: The investigators will ask some questions to determine eligibility to participate in the study. Those who qualify for the study will be invited to participate in an interview that could be completed online or in person (Philadelphia, PA). The interview could last up to 90 minutes (1 and a half hours) and can be completed as one or multiple sessions. For clinicians: Participants will engage in a 90-minute focus group with other clinicians where lunch will be served if in person. Those participating in an online focus group will receive a gift card equal to the value of lunch. In Part 2 (a clinical trial) - The program developed in Part 1 will be tested. The program will be physical activity-based. Specific program details for part 2 will be provided as they emerge. Participants can choose to sign up for either or both parts. Signing up for Part 1 does not mean participants have to sign up for Part 2. Please contact us for any questions.

PURPOSE: To determine validity and reliability of translated Arabic version of the De Morton Mobility index for mobility assessment in patients after abdominal surgeries. BACKGROUND: Major abdominal surgery has a high morbidity and Mortality rate, and the risk of surgical complications is higher than for equivalent elective operations. those receiving emergency laparotomy are in a condition of physiological derangement driven by inflammation that has already occurred prior to surgery, in contrast to those undergoing elective abdominal operations. early mobility and exercise play an important role in postoperative treatment following abdominal surgery and are related with reduced postoperative fitness loss and fewer postoperative complications in individuals undergoing elective surgery. reduced mobility is a primary factor of lower quality of life and decreased social participation. reduced mobility is particularly common in older hospitalized patients, and it leads to an increased risk of falls, longer hospitalizations, more severe impairment and morbidity, and higher mortality rates. To manage elderly patients' mobility function, a reliable and valid mobility assessment tool is required. Performance-based examinations are commonly used to measure the mobility of elderly individuals. The De Morton Mobility Index (DEMMI) was established and validated exclusively for older patients hospitalized in the ward. The DEMMI provides clinicians and researchers with a valid interval-level method for accurately measuring and monitoring mobility levels of acute medical patients. It has been validated also in sub acute hospital and community settings. A DEMMI score of \<40 indicates an independent risk of serious postoperative complications. A low DEMMI score suggested impaired mobilization, and prior research of patients following abdominal surgery discovered that delayed mobilization was related with postoperative pulmonary complications. HYPOTHESES: It will be hypothesized that: Arabic version of the De Morton Mobility Index may be valid and reliable in patients after abdominal surgeries. RESEARCH QUESTION: Is The Arabic version of the De Morton Mobility index valid and reliable for mobility assessment in patients after abdominal surgeries?

The goal of this randomized controlled trial is to compare the short-term effects of a virtual, community-based, task-oriented group exercise program (TIME™ at Home) with a waitlist control in community-dwelling adults with balance and mobility limitations. The main questions the trial aims to answer are: 1. Will there be improvements in physical and mental health outcomes, and caregiver mood and assistance, following participation in the TIME™ at Home exercise program that are greater than in the waitlist control group? 2. Will level of mobility limitation, sex, or gender influence the experiences of people in the exercise program? 3. What will be the costs of the TIME™ at Home exercise program for the organization delivering the program, and the people who are in the exercise program? Participants and their caregivers will be asked to complete 3 evaluations using Zoom at study entry and 2 and 5 months later. * Participants will complete tests of balance and walking and questionnaires. * Caregivers will only complete questionnaires. After the first evaluation, participants will be randomly assigned to either participate in: * the 8-week TIME™ at Home exercise program from their homes using Zoom, or * to wait 5 months (waitlist control group) before beginning the 8-week TIME™ at Home exercise program
