One year of training with FES has impressive beneficial effects in a 36-year-old woman with spinal cord injury
2015
International audience; CONTEXT:Reductions of muscular and cardiorespiratory functions are often observed in people with spinal cord injury (SCI) and several studies demonstrated the benefits of aerobic and strengthening exercise training for this population. Functional Electrical Stimulation (FES) of paralyzed muscles has been proposed as a strategy to assist patients in executing functional movement but its utilization during long durations has never been investigated. The purpose of the present study was to assess the effects of a one-year training program with FES (strengthening and rowing) in one subject with SCI. Evoked torque, quadriceps muscle thickness, aerobic exercise capacity an…
Comparison of ground reaction forces and antagonist muscle coactivation during stair walking with ageing
2006
Abstract Stair walking is a demanding task in old age. Ground reaction force (GRF) analysis, relative EMG activation, and muscular coactivation were performed during stair walking. The aim was to investigate the ageing effect on GRF distribution and muscle antagonist coactivation during stair walking, at varied speed. During ascending at maximal velocity old subjects demonstrated reduced GRF in all examined phases (range: 28–35%), whereas muscle coactivation only was elevated for the Entire stance phase (18.5%). GRF parameters during ascent and descent at freely chosen speed demonstrated differences between age groups (5–28%). Furthermore, muscle coactivation was elevated in old subjects (e…
Influence of training and a maximal exercise test in analytical variability of muscular, hepatic, and cardiovascular biochemical variables.
2014
Short, middle, and long-term exercise, as well as the relative intensity of the physical effort, may influence a broad array of laboratory results, and it is thereby of pivotal importance to appropriately differentiate the 'physiologic' from the 'pathological' effects of exercise. Therefore, the values of some biomarkers in physically active subjects may be cautiously interpreted since the results may fall outside the conventional reference ranges. It has been demonstrated that middle and long-term endurance and/or strenuous exercise triggers transient elevations of muscular and cardiac biomarkers. However, no data have been published about the effect of short-term maximal exercise test on …
A multi-joint lower-limb tracking-trajectory test for the assessment of motor coordination.
2005
This study aimed to determine whether a lower-limb trajectory-tracking task performed on a leg press machine, that is commonly adopted in both rehabilitation and resistance training settings, could yield reliable assessment of motor coordination in able-bodied individuals. Twenty-two female subjects allocated to two experimental groups were tested and retested after 48-72 h. Group A was fully familiarized with the experimental procedures before each test while group B received only verbal instructions. The unilateral coordination test consisted of target tracking during a simulated half squat including eccentric and concentric actions. In both groups, tracking error showed significant test-…
Reliability and validity of the Finnish version of the Lower Extremity Functional Scale (LEFS)
2017
The present study aimed to assess the psychometric properties of the Finnish version of the Lower Extremity Functional Scale (LEFS) among foot and ankle patients.The LEFS was translated and cross-culturally adapted to Finnish. We assessed the test-retest reliability, internal consistency, floor-ceiling effect, construct validity and criterion validity in patients who underwent surgery due to musculoskeletal pathology of the foot and ankle (N = 166).The test-retest reliability was high (ICC = 0.93, 95% CI: 0.91-0.95). The standard error of measurement was 4.1 points. The Finnish LEFS showed high internal consistency (Cronbach's α = 0.96). A slight ceiling effect occurred as 17% achieved the …
Methodical aspects of perceived exertion rating and its relation to pedalling rate and rotating mass.
1975
Methodical aspects of the relationship between pedalling rate and rotating mass and perceived exertion rating (PER; Borg, 1962) were studied in trained, untrained, and ill subjects in bicycle ergometry. Pedalling rate varied between 40 and 100 rpm, work load steps were 5, 10, 15 and 20 mkp/sec in the healthy subjects, and 2.5, 5, 7.5 and 10 mkp/sec in the patients. PER decreased with increasing pedalling rate in all healthy subjects. In the patients, PER increased moderately at work load of 2.5 mkp/sec, but decreased at higher work loads up to 80 rpm, followed by a slight increase at 100 rpm. Higher mass of the flywheel, studied in 6 trained subjects, lowered the PER insignificantly. In the…
Acute effect of induced asymmetrical running technique on foot skin temperature
2020
The aim of the study was to evaluate skin temperature of the soles of the feet before and after a provoked asymmetrical running. Seventeen recreational male runners performed two 15 min running tests in the same session. In the first test, participants performed running without modifying their running technique (control condition). In the second running test, they repeated the same protocol using an ankle weight of 1.5 kg in the non-dominant ankle (asymmetrical condition). Rate of perceive exertion, heart rate and spatio-temporal parameters were measured during the running tests. Skin temperature was measured with an infrared camera before and after each condition. Generally, comparing both…
Application of tRNS to improve multiple sclerosis fatigue: a pilot, single-blind, sham-controlled study
2019
We evaluated the effects of transcranial random noise stimulation (tRNS) on fatigue in 17 subjects with relapsing–remitting multiple sclerosis with low physical disability. Two different patient groups underwent real or sham stimulation for 10 days, targeting the primary motor cortex of the dominant side or contralateral to the most compromised limb. In the ‘real group’, beneficial effects were observed using the Modified Fatigue Impact Scale (p = 0.04; physical subscale: p = 0.03), the subscales ‘change in health’ (p = 0.006) and ‘role limitations due to physical problems’ (p = 0.001) of the Multiple Sclerosis Quality of Life-54, and by assessing the patient impression of perceived fatigue…
Measuring deterioration in international classification of functioning domains of people with multiple sclerosis who are ambulatory.
2007
Background and PurposeMeasures to detect important effects related to physical therapy interventions must be able to detect an important change. The purpose of this study was to select the most responsive physical functioning measures for multiple sclerosis (MS) using the International Classification of Functioning, Disability and Health (ICF) as a framework.SubjectsThe participants were 120 people with MS who were ambulatory from a population-based sample.MethodsPhysical functioning was assessed by quantitative clinical measures of activities (n=5) and body functions (n=7) and by self-reported performance in self-care, mobility, and domestic life domains in the activities and participation…
Effectiveness of Mirror Therapy for Subacute Stroke in Relation to Chosen Factors.
2016
Purpose The aim of this study was to determine the effectiveness of mirror therapy (MT) combined with comprehensive treatment and to investigate the possible relationships of functional state. Design Prospective, controlled trial of 60 stroke inpatients. Methods The Functional Index "Repty" (FIR) was an outcome measure to assess changes of independence in daily activities. The Frenchay Arm Test (FAT) and Motor Status Score were outcome measures to assess changes in hand function. Findings The analysis of pre- and posttest data indicated a significant improvement in hand function ([INCREMENT]FAT in the Mirror group p = .035, N = 30). Age factor indicated a significant change in relation to F…
