Filter by:The benefits of inspiratory muscle training(IMT) in patients with chronic obstructive pulmonary disease(COPD) were reported.But in severe COPD patients, benefit from IMT may be limited.There is need for further research in new and complementary modalities to improve IMT efficiency in severe COPD patients.Manual therapy(MT) additional over IMT may be such a new approach that has not yet been investigated in COPD. Aims: To investigate effects of MT additional over IMT on functional capacity,respiratory muscle strength,pulmonary function,dyspnea, fatigue and quality of life in severe COPD patients. Methods: It was a prospective single-blind randomized trial. 40 patients with COPD in Global Initiative for Chronic Obstructive Lung Disease(GOLD) stage III-IV were included. Patients were randomly assigned to receive either MT additional over IMT at 40% of maximal inspiratory pressure(MIP)(n= 20) or only IMT(n= 20) for 12 weeks. MT group received MT during 12 weeks for 40 minutes additional to IMT. Pulmonary function using spirometry, respiratory muscle strength using mouth pressure device, functional capacity using six minute walk test, dyspnea using Modified Medical Research Council(MMRC) dyspnea scale, fatigue using fatigue severity scale and quality of life using St. George's Respiratory Questionnaire(SGRQ) were evaluated.
Quadriceps muscle dysfunction persists for years after anterior cruciate ligament reconstruction (ACLR) and is related to poor self-reported outcomes, altered movement patterns and joint loading associated with post-traumatic knee osteoarthritis (OA), and higher risk of reinjury. Emerging evidence indicates that central drive (pathway from the brain to the muscle of interest, i.e corticospinal excitability) to the quadriceps muscle is reduced as early as 2 weeks after surgery and can persist for years after ACLR, meaning that current rehabilitation strategies may not be addressing potential maladaptive changes in central drive. Anodal tDCS is a neurostimulation technology that increases brain excitability (i.e. central drive) and has the potential to address alterations in central drive and quadriceps muscle performance. The purpose of this study is twofold: 1) to determine the effects of anodal tDCS on central drive and quadriceps muscle performance in patients after ACLR, and 2) determine the relationship between central drive and quadriceps muscle performance in patients after ACLR. Central drive will be defined by two measures: 1) active motor thresholds, and 2) slope of a stimulus response curve. Quadriceps muscle performance will be defined by two measures: 1) isometric quadriceps strength, and 2) rate of torque development (RTD). For purpose 1 the investigators hypothesize that measures of central drive and quadriceps muscle performance will increase with administration of active anodal tDCS compared to no change with sham tDCS. For purpose 2 the investigators hypothesize that both measures of central drive will be associated with both measures of quadriceps performance, with a stronger association between central drive and RTD. Following a cross-over design patients 3-6 months from ACLR will receive active and sham anodal tDCS at different sessions separated by 7-10 days while they ride a stationary bike for 20 minutes. Bike position and intensity will be standardized for all patients to maximize quadriceps activity. Findings from this study will expand our basic science knowledge on how tDCS effects different aspects of corticospinal excitability and quadriceps strength, and lead to subsequent studies to determine the effects of multiple sessions of tDCS on corticospinal excitability and quadriceps muscle performance in patients recovering from ACLR.
To investigate the efficacy of a 12-week Functional Power Training (FPT) program in pre-frail and frail community-dwelling older adults in Singapore for the management of physical frailty. The proposed study will provide information on the benefits of FPT on physical performances of older adults and help to shape future exercise recommendations to slow or reverse the onset and severity of physical frailty.
While "conditioning" by exercise training has been widely evaluated, the available literature on "passive deconditioning" (i.e. forced deconditioning) is predominately limited to studies with or with almost complete mechanical and/or metabolic immobilization/sedation of the respective functional system (e.g. paralysis, bedriddenness). Vice versa, the effects of moderately long interruptions of dedicated types of exercise while maintaining everyday activity are rarely addressed. However, this topic is of high relevance, e.g. considering that breaks of health-related exercise programs due to increased family/occupational stress, vacation or temporary orthopedic limitation are rather frequent in everyday life. In the present project we aimed to determine the effects of 3 months of physical deconditioning due to COVID-19 induced lockdown after 13 month of high intensity endurance and resistance exercise in early postmenopausal women on parameters related to health and physical fitness.
Introduction: Survivors of acute respiratory failure develop persistent muscle weakness and deficits in cardiopulmonary endurance combining to limit physical functioning. Early data from the Covid-19 pandemic suggest a high incidence of critically ill patients admitted to intensive care units (ICU) will require mechanical ventilation for acute respiratory failure. Covid-19 patients surviving an admission to the ICU are expected to suffer from physical and cognitive impairments that will limit quality of life and return to pre-hospital level of functioning. In this present study, the investigators will evaluate the safety and feasibility of providing a novel clinical pathway combining ICU after-care at an ICU Recovery clinic with physical therapy interventions. Methods and Analysis: In this single-center, prospective (pre, post cohort) trial in patients surviving ICU admission for Covid-19. The investigators hypothesize that this novel combination is a) safe and feasible to provide for patients surviving Covid-19; b) improve physical function and exercise capacity measured by performance on 6-minute walk test and Short Performance Physical battery; and c) reduce incidence of anxiety, depression and post-traumatic stress assessed with Hospital Anxiety and Depression Scale and the Impact of Events Scale-revised. Safety will be assessed by pooled adverse events and reason for early termination of interventions. Feasibility will be assessed by rate of adherence and attrition. Repeated measures ANOVA will be utilized to assess change in outcomes from at first ICU Recovery Clinic follow-up (2-weeks) and 3- and 6-months post hospital discharge. Ethics and Dissemination: The trial has received ethics approval at the University of Kentucky and enrollment has begun. The results of this trial will support the feasibility of providing ICU follow-up and physical therapy interventions for patients surviving critical illness for Covid-19 and may begin to support effectiveness of such interventions. Investigators plan to disseminate trial results in peer-reviewed journals, as well as presentation at physical therapy and critical care national and international conferences.
In recent years, suprainguinal fascia iliaca block (SFIB) has emerged as a reliable analgesic option for primary total hip arthroplasty (THA). In 2018, a new block was described, termed pericapsular nerve group block or PENG block, that selectively targets the articular branches of the femoral and obturator nerves while sparing their motor components. In this randomized trial, the investigators will compare US-guided SFIB and PENG block in patients undergoing primary THA. Since the main benefit of PENGB stems from its quadriceps-sparing effect, it was selected the incidence of quadriceps motor block (at 6 hours) as the primary outcome and the hypothesis that PENG block will result in significantly less motor block compared to SFIB.
The investigators aim to investigate the factors affecting cardiorespiratory fitness in individuals with systemic hypertension.
Low creatinine levels may be a sign of muscle atrophy or weakness, and therefore predictive for respiratory insufficiency in the Intensive care unit (ICU) patients. The investigators compared the outcomes of participants with low creatinine levels with subsequent ICU participants admitted into ICU in the tertiary hospital.
Muscle weakness or atrophy is a common condition following acute and chronic musculoskeletal injuries. Strength training is an imperative component in clinical rehabilitation of musculoskeletal injuries. Heavy exercise loads (approximately 70% of one repetition maximum) is necessary to elicit muscle hypertrophy and strength gains. However, patients with severe muscle atrophy are frequently unable to tolerate these loads due to pain. Blood flow resistance training with low resistance loads may be used to safely develop muscle strength.
Urinary incontinence (UI) symptoms are highly prevalent among women, and menopause is one of the risk factors for UI. During the menopausal transition, not only the hormonal secretion is changed but also the level of physical activity is affected. The time spent on physical activity is reduced in postmenopausal women. Studies have shown that physical activity acts in a bidirectional manner, exerting either a preventive or an aggravating effect on urinary incontinence. Individuals with sedentary lifestyle and insufficient physical activity (< 150 min/week) are at risk of developing UI, and regular physical activity exerts a protective effect in preventing UI, but the optimal type, duration, and intensity of exercise for the female older adult population remain unknown. In addition, objective measurements of pelvic floor muscle function is needed as the use of self-reported measures may cause response bias. The aim of the study is to investigate the effect of different intensity of exercise on pelvic floor muscle function and HRQoL in postmenopausal women with UI. The investigators hypothesize that (a) both high- and low-intensity physical activities can improve pelvic floor muscle strength and HRQoL in postmenopausal women with UI, and (b) the improvement in high-intensity group is higher than that in low-intensity group. A randomized trial will be conducted to compare the effect of different exercise intensity on pelvic floor muscle function in postmenopausal women with urinary incontinence (n=90).
