ABSTRACT
Quadriceps muscle strength was reduced significantly after anterior cruciate ligament reconstruction. Finding a solution to overcome this problem is crucial. The objective of the present study is to investigate the effect of eight weeks cross exercise on the quadriceps muscle strength, in men after anterior cruciate ligament reconstruction. Twenty patients with anterior cruciate ligament tear, with an average age of 22.02 +/- 1.55 years and mean weight of 71.7 +/- 7.15 kilograms, were selected as volunteers. They were divided into two groups: experimental group and control. The experimental group, in addition to physiotherapy, performed eight weeks cross exercise with uninjured leg, three sessions per week and each session lasted for 20 minutes. The control group just received physiotherapy. Before three days of ACLR and After 9 weeks and performing 24 sessions of cross exercise, isometric strength of quadriceps muscle in both groups were measured at 60 degrees of flexion in both legs, by Isokinetic BIODEX system. Data were analyzed by paired and independent samples t-test at a significance level of p<0.05. The results showed that following eight weeks of cross exercise, the quadriceps muscles strength in uninjured leg, in the experimental group was significantly increased [P=0.002]. Likewise, after reconstruction of the ACL, the amount of reduction in quadriceps muscles in the experimental group was significantly lower than the control group [P=0.001]. The degree of strength loss can be positively reduced by continuum concentric cross exercises. Along with the optimization of the healthy organs, these exercises enhance the strength of organs, which underwent surgery
ABSTRACT
Low back pain is the most important health problem in which the complementary therapy, such as water exercise therapy and massage could have a basic role in its treatment. The aim of this study was to compare the effect of water exercise therapy and massage on the pain severity and disability of patients with chronic nonspecific low back pain. In this semi-experimental experiment, 24 male patients with chronic nonspecific lowback pain aged 20-40 years with average age of 27.23 were randomly divided into two groups of "water exercise therapy" and "massage" for treatment. The treatment period lasted 6 weeks and each week consisted of 4 sessions. In order to assess the pain severity and disability, the Oswestry Questionnaires and visual analog score were used respectively before and after the treatment. For data analysis, ANOVA test was applied at the significance level of P
ABSTRACT
The purpose of this study was to investigate the horizontal components of the ground reaction force with subjects' flat foot and to compare these changes with subjects with normal foot. Fifteen subjects were randomly selected from 86 children with flexible flat foot, with a mean age [10.40 +/- 1.12], height [124.60 +/- 8.76] and weight [24.10 +/- 6.70]. 15 subjects were randomly selected to the control group from the population with normal feet that were homogeneous with group flat foot of the height, age and weight. Flat-arched feet were determined by the navicular drop test with Brody method, and 1000Hz KISTLER force plate were used to measure horizontal components of ground reaction force at heel strike [Initial heel contact], transfer weight onto the heel [Loading response], touch the foot of land [Mid stance] and transfer weight onto the toes [Terminal stance] during the Stance phase. Data analysis was performed using SPSS 21 software and independent t-test was used [p< 0.05]. There was a significant difference in the initial heel contact between flat foot and a normal foot. However, no significant difference was noted between the two groups at loading response, mid stance and terminal stance. According to the present research findings, it may be concluded that there are differences between children with flat foot and normal foot in the direction and amount of force at the time of heel strike or initial heel contact
