Background: The transverse abdominis (TrA) muscle is one of the most important muscles that contribute to the stability of the lumbar spine. Strengthening of trunk muscles that have a significant role in trunk stability is very important in the field of professional sport, sport medicine and rehabilitation of patient with low back pain (LBP). Identifying the exercises that can improve the stren...
Loudness of verbal commands affect the Voluntary motor response. It seems the more intensity of verbal command, the more muscle contraction force. The purpose of thisstudy was to investigate the hypothesized effect of verbal command loundness onmagnitude of a resulting voluntary isometric contraction of triceps brachi muscle. Thirthy five female subjectsbetween ages of 18-30 performed f...
Introduction: Thymol has negative ionotropic effect on heart and has direct effect on calcium release from sarcoplasmic reticulum. Some of the herbal plants just like carum copticum consist of thymol. The postganglionic neurons of the gastrointestinal parasympathetic system are located mainly in the myenteric and submucosal plexuses. Stimulation of these parasympathetic nerves causes general...

Background and Objective: Inefficiency of deep cervical flexor muscles are correlated with chronic neck pain. The purpose of this study was to determine and to compare longus colli muscle dimensions between rest and maximum isometric contraction in patients with chronic neck pain and healthy subjects. Materials and Methods: For this case-control study, 16 healthy matched subjects and 16 patient...
Aims and background: This study aimed to investigate the comparison of isokinetic parameters of hip and knee joint muscles in professional soccer players with athletic groin pain (AGP) and healthy ones. Material and Methods: 32 soccer players (control group (n=16) and AGP group (n=16)) who take part in the first and second division league participated in this study. The isokinetic dynamometer ...
proprioceptive neuromuscular facilitation (pnf) training (contraction - relaxation method), in compared to the other methods of static and dynamic stretching exercises; has higher and safer effects on enhancement of hamstring muscle's flexibility, strength and endurance. achieving the optimal combination of contraction and stretching phases in pnf training that can increase these factors of phy...
Background and purpose: The purpose of this study was to assess the Within-day and Between-days reliability of abdominal muscles size measurement in patients with chronic non-specific low back pain (LBP) using ultrasound (US). Materials and methods: In this study, 15 patients with chronic non-specific LBP (20-50 years old) were recruited. The reliability of the abdominal muscle size (External ...
