Effectiveness of technology-based distance interventions promoting physical activity : Systematic review, meta-analysis and meta-regression
2017
Objective: To determine the effectiveness of technology-based distance interventions for promoting physical activity, using systematic review and metaanalysis. Methods: A literature search of studies published between 2000 and 2015 was conducted in the following databases: CENTRAL, EMBASE, Ovid MEDLINE, CINAHL, PsycINFO, OTseeker, WOS and PEDro. Studies were selected according to the PICOS framework, as follows: P (population): adults; I (intervention): technology-based distance intervention for promoting physical activity; C (comparison) similar distance intervention without technology, O (outcomes) physical activity; S (study design) randomized controlled trial. Physical activity outcomes…
Myocardial and peripheral vascular functional adaptation to exercise training.
2007
Exercise training seems to restore impaired vascular function in both peripheral and myocardial vessels in patients with coronary artery and peripheral vascular disease or in patients with risk factors for these diseases. However, the results on the effects of exercise training on vascular function in apparently healthy subjects are controversial. We studied the effects of long-term volitionally increased physical activity on peripheral and myocardial vascular function in nine young healthy male monozygotic twin pairs discordant for physical activity and fitness. The brothers were divided into more (MAG) and less active groups according to physical activity and fitness. The difference betwe…
Knee arthroscopy and exercise versus exercise only for chronic patellofemoral pain syndrome: 5-year follow-up.
2011
Objective To study the long-term outcome of arthroscopy in patients with chronic patellofemoral pain syndrome (PFPS), the authors conducted a randomised controlled trial. The authors also investigated factors predicting the outcome in patients with PFPS. Methods Fifty-six patients with PFPS were randomised into two groups: an arthroscopy group (N=28), treated with knee arthroscopy and an 8-week home exercise programme, and a control group (N=28), treated with a similar 8-week home exercise programme only. The primary outcome was the Kujala score on pain and function at 5-year. Secondary outcomes were visual analogue scales (VASs) to assess activity-related symptoms. Results According to the…
Bilateral ureteral obstruction and renal failure caused by massive retroperitoneal hematoma: is there a pelvic compartment syndrome analogous to abdo…
1998
Objectives: To describe an intrapelvic compartment syndrome analogous to abdominal compartment syndrome and to characterize its diagnosis and treatment. Design: Retrospective analysis. Setting: Level I trauma center. Patients: Three patients with pelvic ring or acetabular fractures presented with bilateral ureteral obstruction, renal organ failure. and anuria due to direct compression of both ureters in the true pelvis by a massive retroperitoneal hematoma, Intervention: Surgical therapy consisted of fracture stabilization, decompression of the retroperitoneal space, and evacuation of the hematoma. Persistent isolated bleeding points were either embolized preoperatively or ligated. Results:…
Effects of treadmill running and fatigue on impact acceleration in distance running
2014
The effects of treadmill running on impact acceleration were examined together with the interaction between running surface and runner's fatigue state. Twenty recreational runners (11 men and 9 women) ran overground and on a treadmill (at 4.0 m/s) before and after a fatigue protocol consisting of a 30-minute run at 85% of individual maximal aerobic speed. Impact accelerations were analysed using two lightweight capacitive uniaxial accelerometers. A two-way repeated-measure analysis of variance showed that, in the pre-fatigue condition, the treadmill running decreased head and tibial peak impact accelerations and impact rates (the rate of change of acceleration), but no significant differenc…
Effect of 3 Weeks Use of Compression Garments on Stride and Impact Shock during a Fatiguing Run
2015
Excessive and prolonged exposure to impact acceleration during running is associated with increased injury rate. Acute use of compressive garments has been speculated to improve attenuation. However, it is unknown how longer interventions of compressive garments influence attenuation in running. 40 runners trained with compressive and placebo stockings for 3 weeks. Perception of comfort, stride parameters (rate, length) and impact acceleration (head and tibial peak acceleration, magnitude, acceleration rate and attenuation) were measured every 5 min during a fatigue run (30 min at 80% of the individual's maximal aerobic speed). Compressive stockings reduced tibial peak acceleration and magn…
Long-term functional results of digital replantation: A survey of 28 patients
2019
We sought to evaluate the long-term quality of life and functional outcome of patients who underwent digital replantation after amputation. A retrospective single-center study was conducted of patients treated between January 2010 to May 2016. Twenty-eight patients who underwent successful replantation after single or multiple digital amputation were reviewed in person after at least 2years' follow-up (mean 4.6years). Total active range of motion, grip and pinch strength were assessed. Functional outcomes were evaluated using the SF-36 and DASH questionnaires. The patients' occupational status and daily activities were reported. Mean total active range of motion was 42% of the contralateral…
Changes in catastrophizing and kinesiophobia are predictive of changes in disability and pain after treatment in patients with anterior knee pain
2014
Purpose. The purpose of the study was to investigate if changes in psychological variables are related to the outcome in pain and disability in patients with chronic anterior knee pain. Methods. A longitudinal observational study on 47 patients with chronic anterior knee pain was performed in a secondary healthcare setting. Pain was measured with the visual analogue scale and disability with the Lysholm scale. The psychological variables, such as anxiety, depression, pain coping strategies, catastrophizing and fear to movement beliefs, were studied by using self-administered questionnaires. Results. Among the pain coping strategies, only the catastrophizing subscale showed a significant red…
Maximal Aerobic Power Characteristics of Male Professional Soccer Players, 1989–2012
2013
Purpose:The purpose of this investigation was to quantify maximal aerobic power (VO2max) in soccer as a function of performance level, position, age, and time of season. In addition, the authors examined the evolution of VO2max among professional players over a 23-y period.Methods:1545 male soccer players (22 ± 4 y, 76 ± 8 kg, 181 ± 6 cm) were tested for VO2max at the Norwegian Olympic Training Center between 1989 and 2012.Results:No differences in VO2max were observed among national-team players, 1st- and 2nd-division players, and juniors. Midfielders had higher VO2max than defenders, forwards, and goalkeepers (P < .05). Players <18 y of age had ~3% higher VO2max than 23- to 26-y-old…
Reproducibility of isometric strength: measurement of neck muscles
1999
Abstract Objective. To evaluate the repeatability of an advanced method of measuring the strength of functionally different groups of neck muscles using an isometric apparatus. Design. A repeated measures design was used within and between sessions. Background. Chronic neck pain has been associated with poor isometric neck strength. In rehabilitation, strength measurements may thus help to evaluate the basic condition and show whether or not treatments and exercises have been beneficial for improving strength. Previous tests have concentrated on testing strength while trying to bend forwards and backwards, but no biomechanics device, able to test rotator muscles, has been presented. Method.…
