introduction: according to the importance of the back extensor muscle strength in postmenopausal women, this study aimed to determine the relationship between strength and changes in the thickness of back extensor muscles during isometric contraction in healthy and osteoporotic postmenopausal women. material and methods: 42 volunteer postmenopausal women according to their bone mineral density ...
Background and purpose: Ultrasonography is a reliable and valid method to assess the strength of neck extensors and measuring the neck muscles dimensions. Cervical muscles strength and dimensions may change in different positions. The aim of this study was to compare the strength of cervical extensor muscles and dimensions of semi-spinalis capitis muscle (SECM) in three different neck positions...
background: forward head posture (fhp) is recognized as a common postural disorder of modern societies. increase in anterior cervical convexity and anterior displacement of the line of gravity of head in individuals with fhp is assumed to result in altered moment arms and muscle activity on cervical spine. measurement of muscle thickness seems to be an appropriate index for muscle activity. thi...
background: exercise is a widely prescribed treatment for chronic low back pain. the purpose of the present study was to investigate the effect of 8 weeks exercise on pain, disability and endurance of trunk flexor-extensor muscles in female with chronic idiopathic low back pain. methods: this clinical trial study has been done on 12 patients who referred to the arak city clinics. the function o...
Objective: Neck pain is one of the most common musculoskeletal disorders. Structural and functional alteration of cervical muscles is a commonly-reported complication of chronic neck pain (CNP). Measurement of muscle thickness is an acceptable way to evaluate muscle morphological structure. Therefore, this study aimed to measure cervical extensor muscles thickness in individuals with chronic no...
Background and purpose: Strengthening the cervical extensor muscles is recommended as a way of prevention and treatment of neck pain. The purpose of this study was to investigate the effect of two different exercise protocols on isometric strength of the head and neck extensor muscles in healthy subjects. Material and Methods: In this study, a total of twenty-eight healthy females, 20-25 yea...
In this investigation we have estimated the afferent contribution to the generation of activity in the knee and ankle extensor muscles during walking in decerebrate cats by loading and unloading extensor muscles, and by unilateral deafferentation of a hind leg. The total contribution of afferent feedback to extensor burst generation was estimated by allowing one hind leg to step into a hole in ...
Rates of protein synthesis were significantly lower in the cut soleus and extensor digitorum longus muscles than in their uncut counterparts. Rates of protein degradation were significantly higher in cut soleus muscles, but not in cut extensor digitorum longus muscles as compared with their uncut controls. Concentrations of ATP and phosphocreatine were significantly lower in cut soleus and exte...
Usually the dorsal surface of the hand is devoid of muscle bellies, it only contains the tendons of the extensor muscles of the hand. Between the dorsal carpal ligament and the carpal bones six compartments are formed for the passage of tendons. Found on the dorsum of the hand are the tendons of the extensor pollicis longus, extensor digitorum communis, extensor indicis (extensor indicis propri...
