Wrist-worn accelerometers in assessment of energy expenditure during intensive training
2012
We assessed the ability of the Polar activity recorder (AR) to measure energy expenditure (EE) during military training. Twenty-four voluntary male conscripts participated in the study and wore an AR on the non-dominant wrist 24 h a day for 7 d. The AR analyzed and stored the frequency of hand movements (f_hand) into memory at 1 min intervals. The relationship between f_hand and EE was studied over a 7 d period of military training using the doubly labeled water (DLW) technique. In addition, the relationship between f_hand and EE was analyzed during walking and running on a treadmill with an indirect calorimeter (IC), and f_hand was measured during a supervised 45 min field march test where…
Balance Confidence Was Associated With Mobility and Balance Performance in Older People With Fall-Related Hip Fracture: A Cross-Sectional Study
2012
Abstract Portegijs E, Edgren J, Salpakoski A, Kallinen M, Rantanen T, Alen M, Kiviranta I, Sihvonen S, Sipila S. Balance confidence was associated with mobility and balance performance in older people with fall-related hip fracture: a cross-sectional study. Objective To study the relationship between balance confidence, a concept closely related to fear of falling, mobility and balance performance, and perceived mobility limitation in older people after a fall-related hip fracture. Design Cross-sectional analyses of pretrial data of 2 randomized controlled trials of physical rehabilitation. Setting University research center. Participants Community-dwelling people aged over 60 years, 6 week…
Structural validity of the Finnish Manchester-Oxford Foot Questionnaire (MOXFQ) using the Rasch model.
2019
Background: The 16-item patient-reported Manchester-Oxford Foot Questionnaire (MOXFQ) with subscales of pain, social interactions, and walking/standing has been claimed for strongest scientific evidence in measuring foot and ankle complaints. This study tests the validity of the Finnish MOXFQ for orthopaedic foot and ankle population using the Rasch analysis. Methods: We translated the MOXFQ into Finnish and used that translation in our study. MOXFQ scores were obtained from 183 patients. Response category distribution, item fit, coverage, targeting, item dependency, ability to measure latent trait (unidimensionality), internal consistency (Cronbach's alpha), and person separation index (PS…
Improvement of motor performance by observational training in elderly people.
2010
Action observation influences action execution; this strong coupling is underlined by an overlap of cortical areas activated during observation and execution of action, and is dependent of specific motor experience. The goal of the present study was to verify if action observation can be used for rehabilitation of elderly people. We tested this question with a protocol of observational practice of 2 frequently used movements: walking and sit-to-stand/back-to-sit. Both tasks were performed at normal and maximal speed before and after training, by 8 elderly subjects. Observational practice led to an increase in walking velocity via an increase in step frequency, but without modification of st…
Effects of physical and cognitive training on gait speed and cognition in older adults: A randomized controlled trial
2021
Gait speed is a measure of health and functioning. Physical and cognitive determinants of gait are amenable to interventions, but best practices remain unclear. We investigated the effects of a 12-month physical and cognitive training (PTCT) on gait speed, dual-task cost in gait speed, and executive functions (EFs) compared with physical training (PT) (ISRCTN52388040). Community-dwelling older adults, who did not meet physical activity recommendations, were recruited (n = 314). PT included supervised walking/balance (once weekly) and resistance/balance training (once weekly), home exercises (2-3 times weekly), and moderate aerobic activity 150 min/week in bouts of >10 min. PTCT included the…
Supervised exercise training in peripheral arterial disease increases vascular shear stress and profunda femoral artery diameter
2016
Background Arteriogenesis is promoted by flow- and pressure-related forces such as tangential wall stress and laminar shear stress. Exercise training (ET) is known to promote arteriogenesis in peripheral arterial disease (PAD) patients. It remains unclear whether supervised ET (SET) promotes arteriogenesis more efficiently than non-SET (nSET). Methods and results Forty PAD patients participated in a SET or nSET training programme ( n = 20 each) and were compared to 20 healthy individuals without any history of cardiovascular events. Femoral artery diameter, flow and velocity were measured by ultrasound. Tangential wall stress and laminar shear stress were calculated for femoral arteries. Fo…
EVALUATION OF LOW-ENERGY EXTRACORPOREAL SHOCK-WAVE APPLICATION FOR TREATMENT OF CHRONIC PLANTAR FASCIITIS
2002
Background: Although the application of low-energy extracorporeal shock waves to treat musculoskeletal disor- ders is controversial, there has been some limited, short-term evidence of its effectiveness for the treatment of chronic plantar fasciitis. Methods: From 1993 to 1995, a prospective, two-tailed, randomized, controlled, observer-blinded pilot trial was performed to assess whether three applications of 1000 impulses of low-energy shock waves (Group I) led to a su- perior clinical outcome when compared with three applications of ten impulses of low-energy shock waves (Group II) in patients with intractable plantar heel pain. The sample size was 112. The main outcome measure was patien…
Effects of inspiratory muscle training in patients with heart failure with preserved ejection fraction
2013
Heart failure with preserved ejection fraction (HFpEF) is remarkably common in elderly people with highly prevalent comorbid conditions. Despite its increasing in prevalence, there is no evidence-based effective therapy for HFpEF. We sought to evaluate whether inspiratory muscle training (IMT) improves exercise capacity, as well as left ventricular diastolic function, biomarker profile and quality of life (QoL) in patients with advanced HFpEF and nonreduced maximal inspiratory pressure (MIP).A total of 26 patients with HFpEF (median (interquartile range) age, peak exercise oxygen uptake (peak VO2) and left ventricular ejection fraction of 73 years (66-76), 10 ml/min/kg (7.6-10.5) and 72% (6…
Loading and gait symmetry during level and stair walking in asymptomatic subjects with knee osteoarthritis: importance of quadriceps femoris in reduc…
2007
Repetitive impulsive forces during walking are claimed to result in joint osteoarthritis (OA). The aim of this study was to investigate impact loading and gait symmetry during level and stair walking in asymptomatic elderly subjects with knee OA. It was hypothesised that pre-activity of the quadriceps femoris muscle (QF) would be an important factor reducing impulsive loading when walking on level ground. Subjects [21 female, six men, 66.2 (7.6) years] were studied. The subjects had no knee pain or diminished functional capacity, but showed radiographically light or moderate bilateral knee OA changes. Ground reaction forces (GRFs), plantar pressure distribution, muscle activation pattern [v…
Validity and reliability of isometric, isokinetic and isoinertial modalities for the assessment of quadriceps muscle strength in patients with total …
2013
Reliability of isometric, isokinetic and isoinertial modalities for quadriceps strength evaluation, and the relation between quadriceps strength and physical function was investigated in 29 total knee arthroplasty (TKA) patients, with an average age of 63 years. Isometric maximal voluntary contraction torque, isokinetic peak torque, and isoinertial one-repetition maximum load of the involved and uninvolved quadriceps were evaluated as well as objective (walking parameters) and subjective physical function (WOMAC). Reliability was good and comparable for the isometric, isokinetic, and isoinertial strength outcomes on both sides (intraclass correlation coefficient range: 0.947-0.966; standard…
