Region-dependent hamstrings activity in Nordic hamstring exercise and stiff-leg deadlift defined with high-density electromyography
2018
Recent studies suggest region-specific metabolic activity in hamstring muscles during injury prevention exercises, but the neural representation of this phenomenon is unknown. The aim of this study was to examine whether regional differences are evident in the activity of biceps femoris long head (BFlh) and semitendinosus (ST) muscles during two common injury prevention exercises. Twelve male participants without a history of hamstring injury performed the Nordic hamstring exercise (NHE) and stiff-leg deadlift (SDL) while BFlh and ST activities were recorded with high-density electromyography (HD-EMG). Normalized activity was calculated from the distal, middle, and proximal regions in the e…
Differences in ground reaction forces and shock impacts between nordic walking and walking.
2014
The regular practice of Nordic walking (NW) has increased in recent years, in part thanks to the health benefits described by the scientific literature. However, there is no consensus on the effects of shock-impact absorption during its practice. Purpose: The aim of this study was to compare the levels of impact and ground reaction forces (GRF) between NW and walking (W). Method: Twenty physically active and experienced participants were assessed using a dynamometric platform and accelerometry analysis. Results: The results show statistically significantly higher levels of acceleration in the tibia (12%) and head (21%) during NW compared with W. Equally, GRF were significantly higher (27%) …
Changes in Health Utility, Disability, and Health-Related Quality of Life in Patients After Spinal Fusion
2014
STUDY DESIGN Prospective longitudinal database study. OBJECTIVE To evaluate changes in health utility, disability, and health-related quality of life (HRQOL) in patients undergoing spinal fusion. SUMMARY OF BACKGROUND DATA Recently, measuring disability, HRQOL, and health utility has become important when defining the value of surgical interventions. METHODS Data of spinal fusion patients from a prospective longitudinal database were analyzed. Health utility was captured by SF-6D (six dimensional health state classification from the 36-dimensional Short Form Health Survey) score, disability by Oswestry Disability Index, and HRQOL by the 36-Item Short Form Health Survey. The changes in these…
Effect of overground vs treadmill running on plantar pressure: Influence of fatigue
2013
Abstract The differences produced when running on a treadmill vs overground may call into question the use and validity of the treadmill as a piece of equipment commonly used in research, training, and rehabilitation. The aim of the present study was to analyze under pre/post fatigue conditions the effect of treadmill vs overground on plantar pressures. Twenty-seven recreational runners (17 men and 10 women) ran on a treadmill and overground at two speeds: S 1 = 3.33 m/s and S 2 = 4.00 m/s, before and after a fatigue protocol consisting of a 30-min run at 85% of their individual maximal aerobic speed (MAS). Contact time (CT in seconds), peak pressure (PP in kPa), and relative load (RL in …
Low-energy extracorporeal shock wave therapy for painful heel: a prospective controlled single-blind study.
1996
The aim of this prospective single-blind pilot study was to explore the pain-alleviating effect of low-energy extracorporeal shock wave therapy (ESWT) in painful heel associated with inferior calcaneal spurs. Thirty patients who suffered from persistent symptoms for more than 12 months qualified for low-energy ESWT and were assigned at random to two groups, real or simulated ESWT. Before beginning the treatment, any other therapy was stopped for a period of 6 weeks. The shock waves were applied by an experimental device allowing exact localization through an integrated fluoroscopy unit. Patients were treated three times at weekly intervals. Each time 1000 impulses of 0.06 mJ/mm2 were given …
Repetitive low-energy shock wave application without local anesthesia is more efficient than repetitive low-energy shock wave application with local …
2005
Background: It remains unclear whether application of local anesthesia (LA) interferes with clinical e!cacy of extracorporeal shock wave therapy (ESWT) for chronic plantar fasciitis. Aims: To evaluate the e"ect of local anesthesia on the clinical outcome after repetitive low-energy ESWT for chronic plantar fasciitis. Methods: Eighty-six patients with chronic plantar fasciitis were randomly assigned to receive either low-energy ESWT without LA, given weekly for three weeks (Group I, n = 45; 3 · 2000 pulses, total energy flux density per shock 0.09 mJ/mm 2 ) or identical ESWT with LA (Group II, n = 41). Primary outcome measure was: Reduction of pain from baseline to month 3 post-treatment in …
Five times sit-to-stand test in subjects with total knee replacement: Reliability and relationship with functional mobility tests
2017
The objective was to determine the inter-observer and test/retest reliability of the "Five-repetition sit-to-stand" (5STS) test in patients with total knee replacement (TKR). To explore correlation between 5STS and two mobility tests. A reliability study was conducted among 24 (mean age 72.13, S.D. 10.67; 50% were women) outpatients with TKR. They were recruited from a traumatology unit of a public hospital via convenience sampling. A physiotherapist and trauma physician assessed each patient at the same time. The same physiotherapist realized a 5STS second measurement 45-60min after the first one. Reliability was assessed with intraclass correlation coefficients (ICCs) and Bland-Altman plo…
Effects of in-play cooling during simulated tennis match play in the heat on performance, physiological and perceptual measures
2021
BACKGROUND: The aim of this crossover study was to investigate whether a cooling intervention during simulated tennis match play in the heat could affect players' performance, physiology, perception of effort, and well-being. METHODS: Eight competitive male tennis players performed two testing sessions of 45-minute simulated tennis match play on a hard court at 31.8±2.1°Cand 48.5±9.6% relative humidity. During change-of-end breaks, the cooling interventions (COL) consisted of cold-water ingestion (ad libitum) and an electric fan facing the players at a distance of 1 m combined with an ice-filled damp towel around the neck and on the thighs or no cooling (CON) were applied. Measures of perfo…
Clinical performance of a new medullary humeral nail: antegrade versus retrograde insertion.
2001
Objective A new intramedullary nail system for humeral shaft fractures is evaluated to determine whether retrograde nailing is as reliable as antegrade nailing. Study design Prospective multicenter nonrandomized clinical study. Patients Eighty-four patients with acute humeral shaft fractures were nailed with the new unreamed humeral nail (UHN) system. Fifty-seven nails were introduced retrogradely, and twenty-seven antegradely. Bone healing and functional outcome were the follow-up parameters. Results The ratio of perioperative complications was equivalent for both groups, but one shaft fracture and three fractures or fissures at the entry point occurred in the group with retrograde nail in…
