Background and Objectives: Low back pain is a musculoskeletal disorder with an annual prevalence of 18.6%. The aim of the present study was to evaluate the effect of rehabilitation with medicine ball on directed and general co-contraction of knee joint muscles in low back patients during walking, Materials and Methods: The present study was a clinical trial. The statistical population of the p...
introduction: after low back pain, the neck pain is the most prevalent pain among (especially elderly) peoples. the purpose of this study was to determine the effect of one period of exercise program on subjects neck rom and chronic neck pain. materials and methods: for executing this study 60 elderly patient (24 males and 36 females) with mean age 56± 4.5 years old and 71± 4.4 kg with chronic...
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 and purpose: Impaired function of trunk extensor endurance is known as a risk factor and clinical sign for low-back pain. The aim of this study was to determine the relationship between selected back muscles fatigue index and hyperlordosis. Materials and methods: This case-control study was carried out in 12 males diagnosed with hyperlordosis and 12 with normal lumbar curve. Surface...
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...
[Purpose] Sitting position is the dominant position for a professional pianist. There are many static and dynamic forces which affect musculoskeletal system during sitting. In prolonged sitting, these forces are harmful. The aim of this study was to compare pianists' back extensor muscles activity during playing piano while sitting on a regular piano bench and a chair with back rest. [Subjects ...
Today, Isostation B-200 is one of the most familiar for assessing low back muscles function.This study that is a Quasi-Experimental design was done on 30 healthy men (mean age~26.4 years). The aim of this research is to determine the best and worst motor efficiency in standing and sitting position following torque measurement. In this research maximum torque of low back extensor muscles...
