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…
Relationship between erectile dysfunction and silent myocardial ischemia in type 2 diabetic patients with no known macrovascular complications.
2011
ABSTRACT Introduction Erectile dysfunction (ED) is associated with cardiovascular disease (CVD) because it is highly prevalent among those with cardiovascular risk factors (CVRFs). Moreover, it precedes the development of CVD and is considered a subrogate marker of subclinical CVD. Aim The aim of this study was to evaluate the presence of ED among patients with type 2 diabetes (DM2) without macroangiopathy, and to assess the association between ED and other CVRFs, chronic diabetes complications, silent myocardial ischemia (SMI), and peripheral arterial disease (PAD). Methods One hundred fifty‐four male patients with DM2 and without clinical evidence of CVD were included in the study. The pr…
Serum 25-hydroxyvitamin D and the incidence of peripheral artery disease in the elderly: The Pro.V.A study
2015
Aim: This study was conducted to examine whether low serum levels of 25-hydroxyvitamin D (250HD) are associated with a higher risk of incident peripheral artery disease (PAD) in a representative group of elderly people. Methods: We followed 1568 community-dwelling elderly participants without PAD at the baseline among a sample of 2097 initially eligible over a mean of 4.4 years as part of the Progetto Veneto Anziani (Pro.V.A.) study. The baseline serum 250HD levels were categorized as <24, 25-49, 50-74, >75 nmol/L, and incident PAD was defined as an ankle-brachial index below 0.9. Results: At the baseline, there were no differences in known risk factors for PAD (BMI), waist circumfere…
Effects of Joint Kinetics on Energy Cost during Repeated Vertical Jumping
2019
The present study was designed to investigate the effects of lower limb joint kinetics on energy cost during jumping.Eight male middle and long-distance runners volunteered for the study. The subjects were asked to repeat vertical jumps at a frequency of 2 Hz for 3 min on a force platform in three different surface inclination conditions: Incline (+8°), Level (0°), and Decline (-8°). Sagittal plane kinematics were obtained using a high-speed video camera. Simultaneously, ground reaction forces and EMG of the lower limb muscles were recorded. Energy cost was calculated using steady-state oxygen uptake, respiratory ratio, and vertical distance of the body.In all conditions, energy cost correl…
Association between lower extremity muscle strength and acute ankle injury in youth team-sports athletes
2021
Abstract Objectives To investigate lower extremity muscle strength as risk factor for an acute ankle injury in youth athletes. Design Cohort study. Setting Basketball and floorball clubs. Participants 188 youth (≤21) male and 174 female athletes. Main outcome measures 1RM leg press, maximal concentric isokinetic quadriceps and hamstrings as well as maximal isometric hip abductor strength were measured and athletes were followed for an acute ankle injury up to three years. Cox regression models were used in statistical analyses. Results In males, greater 1RM leg press and maximal quadriceps strength increased the risk of any type of acute ankle injury (Hazard ratio [HR] for 1 SD increase, 1.…
Acute injuries in Finnish junior floorball league players
2018
Abstract Objectives To investigate the incidence and characteristics of acute time-loss injuries in Finnish junior floorball league players. Design Prospective cohort study with 3-year follow-up. Methods One hundred and eighty-six female and male players (mean age 16.6 ± 1.4) took part in the follow-up study (2011–2014). The training hours and games were recorded on a team diary. Floorball related acute injuries were registered and verified by a research physician. The injury incidence was expressed as the number of injuries per 1000 h of exposure. Incidence rate was calculated separately for games and practices, and for males and females. Results One hundred and forty-four acute time-loss …
Stiffness degree of ankle range of motion in diabetic patients with atypical amputation
2020
SUMMARY In diabetics, foot deformities are risk factors that increase the risk of amputation as a result of developing ulcers. However, knowledge of the influence of plantar stiffness is still limited. The main objective was to describe connections between the degree of stiffness of the ankle, atypical amputation, and the Foot Posture Index (FPI). METHODS 62 diabetic patients, 58 with type 2 and 4 with type 1 (average age 63.35 years) were included. Records of foot deformities were included; A range of motion test of the ankle joint was used to determine the degree of stiffness. An exploratory analysis of the association of foot position and the degree of rigidity was performed. RESULTS The…
Repeatability and sensitivity of passive mechanical stiffness measurements in the triceps surae muscle‐tendon complex
2021
Measurements of muscle-tendon unit passive mechanical properties are often used to illustrate acute and chronic responses to a training stimulus. The purpose of this study was to quantify the inter-session repeatability of triceps surae passive stiffness measurements in athletic and non-athletic populations, with the view to discussing its usefulness both as a muscle-tendon profiling tool and a control measure for studies with multiple data collection sessions. The study also aimed to observe the effects of quiet standing on passive stiffness parameters. Twenty-nine men (10 cyclists, nine triathletes, 10 controls) visited the laboratory on three separate occasions, where passive stiffness t…
Differences in gait characteristics between total hip, knee, and ankle arthroplasty patients: a six-month postoperative comparison.
2013
International audience; BACKGROUND: The recovery of gait ability is one of the primary goals for patients following total arthroplasty of lower-limb joints. The aim of this study was to objectively compare gait differences of patients after unilateral total hip arthroplasty (THA), total knee arthroplasty (TKA) and total ankle arthroplasty (TAA) with a group of healthy controls. METHODS: A total of 26 TAA, 26 TKA and 26 THA patients with a mean (+/- SD) age of 64 (+/- 9) years were evaluated six months after surgery and compared with 26 matched healthy controls. Subjects were asked to walk at self-selected normal and fast speeds on a validated pressure mat. The following spatiotemporal gait …
Validity of five foot and ankle specific electronic patient-reported outcome (ePRO) instruments in patients undergoing elective orthopedic foot or an…
2019
Background: Patient-reported outcomes (PROS) are widely accepted measures for evaluating outcomes of surgical interventions. As patient-reported information is stored in electronic health records, it is essential that there are valid electronic PRO (ePRO) instruments available for clinicians and researchers. The aim of this study was to evaluate the validity of electronic versions of five widely used foot and ankle specific PRO instruments. Methods: Altogether 111 consecutive elective foot/ankle surgery patients were invited face-to-face to participate in this study. Patients completed electronic versions of the Foot and Ankle Ability Measure (FAAM), the Foot and Ankle Outcome Score (FAOS),…
