BACKGROUND The extent to which muscle length affects force production in paretic lower limb muscles after stroke in comparison to controls has not been established. OBJECTIVES To investigate knee flexor strength deficits dependent on hip joint position in adults with hemiparesis and compare with healthy controls. METHOD a cross-sectional study with ten subjects with chronic (63±40 months) h...

Objective Startling acoustic stimulation (SAS), via activation of reticulospinal (RS) pathways, has shown to increase muscle strength in healthy subjects. We hypothesized that, given RS hyperexcitability in stroke survivors, SAS could increase muscle strength in stroke survivors. The objective was to quantify the effect of SAS on maximal and sub-maximal voluntary elbow flexion on the contralesi...

Purpose: To determine whether Myofascial Release (MFR) technique in upper cervical region is more effective than using conventional exercises to improve cervical muscle strength in patients with cervicogenic headache. Design: Randomized Controlled Trial. Setting: An outpatient physical therapy clinic, University of social welfare and rehabilitation science, Iran. Methods: We conducted a prospe...

 Background: Lower limbs antigravity muscles weakness and decreased functional ability have significant role in falling. The aim of this study was to find the effects of aging on muscle strength and functional ability, determining the range of decreasing strength and functional ability and relationship between them in healthy women. Methods: Across-section study was performed on 101 healthy wom...

The reduction in steady-state isometric torque following a shortening muscle action when compared to a purely isometric contraction at the same muscle length and level of activation is termed torque depression (TD). The purpose of this study was to investigate spinal and supraspinal neural responses during the TD state of a maximal voluntary activation of the ankle dorsiflexors. Thirteen subjec...

The objective of this study was to investigate the relationship between isometric GM torque and the degree of frontal plane pelvic drop during running. Twenty-one healthy, recreational runners (9 males, 12 females) who ran 8.05 km or more per week were obtained from a sample of convenience. GM maximal isometric torque was collected prior to the run. Subjects then ran on a treadmill for 30 minut...

BACKGROUND Light-emitting diodes (LED) have been used to minimize muscle fatigue in athletes and healthy subjects. Patients with chronic obstructive pulmonary disease (COPD) are susceptible to early muscle fatigue. OBJECTIVE The objective of this study is to investigate the acute effects of LED on muscle function, exercise capacity and cardiorespiratory responses during isometric and dynamic ...

AIM To investigate whether there is a sex difference in exercise induced muscle damage. MATERIALS AND METHOD Vastus Lateralis and patella tendon properties were measured in males and females using ultrasonography. During maximal voluntary eccentric knee extensions (12 reps x 6 sets), Vastus Lateralis fascicle lengthening and maximal voluntary eccentric knee extensions torque were recorded eve...

Although evidence has been presented that, at low ionic strength, myosin heads in relaxed skeletal muscle fibers form linkages with actin filaments, the effect of low ionic strength on contraction characteristics of Ca(2+)-activated muscle fibers has not yet been studied in detail. To give information about the mechanism of muscle contraction, we have examined the effect of low ionic strength o...
