Background: The aim of this study was to investigate the response of ERK1/2 protein and muscular morphological adaptations to a period of resistance training with local blood flow restriction. Materials and methods: Twenty healthy male Wistar rats without clinically evident disease (5 weeks old, 120±7 g weight) were divided into four equal groups: control, control with limited blood flow...
Introduction: Electrical stimulation has been used for many years in rehabilitation medicine to prevent atrophy or to increase muscle strength, but the use of electrical stimulation for muscle strengthening in research and clinical practice has become increasingly popular in recent years. The quadriceps femoris is the thigh muscle group that suffers the greatest amount of atrophy. This study ai...
1. The relationship between joint damage, quadriceps weakness and arthrogenic muscle inhibition was investigated in eight patients who had sustained extensive traumatic knee injury. Isometric and isokinetic quadriceps and hamstring voluntary strength, and quadriceps arthrogenic muscle inhibition during isometric contractions, were measured before and after 4 weeks (approximately 100 h) of inten...
The purpose of this study was to examine the effectiveness of an electronic muscle stimulator in strengthening normal quadriceps femoris muscle without the assistance of simultaneous isometric muscle contraction. The sample consisted of 58 subjects who were randomly divided into three independent groups. One group (n = 19) served as controls; one group (n = 20) underwent daily stimulation of th...
One of the most important causes of patellofemoral pain syndrome is malfunction of quadriceps muscle, specially vastus medialis muscle weakness. Twenty seven normal healthy subjects (21.4±3.4 years) and 17 patients with patellofemoral pain (24.1±3.6 years) were included in this study. Recruitment Internal of the patients and normal subjects were recorded by using a coaxial needle electrode ...
Introduction: Delayed Onset Muscle Soreness (DOMS) is a common strain resulting during therapeutic exercise with eccentric contractions. This pain can result in loss of interest by the patient and eventually in cancellation of the routine. The purpose of the present study was to determine whether vibration could have an affect on delayed onset muscle soreness. We hypothesized that the vibration...
Background and Objective: Muscle weaknesse particularly in association with quadriceps muscle is known as a risk factor in the development and progression of knee osteoarthritis (KOA). The objective of this study was to compare quadriceps muscle strength (QMS) between asymptomatic controls and KOA patients and to elucidate its relationship with knee pain and radiographic changes. Materials a...
BACKGROUND The objective of this study was to clarify the association of quadriceps muscle strength with knee pain using a large-scale, population-based cohort of the Research on Osteoarthritis/osteoporosis Against Disability (ROAD) study. METHODS From the 2566 subjects at the third visit of the ROAD study, the present study analyzed 2152 subjects who completed radiographic examinations and m...
BACKGROUND Quadriceps weakness is common after anterior cruciate ligament injury, especially in those who do not compensate well for the injury ("noncopers"). Both atrophy and activation failure have been demonstrated in this population but have not been directly related to quadriceps weakness. HYPOTHESES (1) Quadriceps strength, volumes, and cross-sectional areas of the noncopers would be sm...
objectives: to investigate the clinical efficacy of physiotherapy with and without superficial dry needling on patients with knee pain; patellofemoral pain syndrome. methods: a randomized clinical trial conducted in 2015, tehran, iran. of patients with patellofemoral pain syndrome, thirty-four subjects were randomly divided into two groups (17 in each group). group a was subjected to physiother...
