ABSTRACT
Purpose: The forward shoulder [FS] is one of the most common deformities accounted for 60% of shoulder abnormalities.This study aimed to investigate the effects of a 6-weekstrength training, stretch training andcomprehensive training in patients with forward shoulder abnormalities
Methods:This quasi-experimental study design Pre-posttest with control group. Forty females students with excessive forward shoulder angle [FS>52] were chosen using purposive sampling method. The average of age, weight, height and body mass index of the samples were 22.22 +/- 1.77 years, 61.22 +/- 1.90 kg, 161.85 +/- 2.55 cm, and 23.37 +/- 0.9kg.m2 respectively. The subjects were randomly divided into 4 groups [each 10 subjects], 3 experimental and 1 control groups. The first experimental group performed strength training, second group stretch training and third group comprehensive training for 6 weeks. In this period, the control group did not receive any training. We used photogrammetric method to measure the angle of the forward shoulder. Shoulder angle changes of the subjects before and after 6 weeks were measured. Data were analyzed using paired T-test, One-way analysis of variance and SPSS [21] [P
Results: According to study findings, paired t-test results in the experimental group showed that the forward shoulder angle of the subjects in corrective exercises significantly decreased so that after participating in 3 types of training program, strengthening[P=0.001, t=8.63], stretching [P=0.001, t=6.78] and comprehensive [P=0.001, t=12.11], the angle dropped in the order of 6.10, 4.90 and 7.10 degrees. One-way analysis of variance [ANOVA] showed that there are significant differences [P=0.001] among the effects of different exercises on the forward shoulder angle. Based on Tukey test results, the implementation of corrective exercises, strengthening [P=0.001], stretching [P=0.001], and comprehensive [P=0.001] showed a significant difference with the control group. However, no significant differences were observed among the groups of strength, stretching and comprehensive trainings with each other
Conclusion: The results demonstrated a significant decrease in the angle of forward shoulder in the experimental group. Therefore, using this program is recommended in subjects with these deformity
ABSTRACT
Osteoarthritis is the commonest form of arthritis and is considered to be one out of ten major causes of disability in the world. The objective of present study was to investigate the effect of treadmill exercise alone and in combination with quercetin supplementation on male rats' knee osteoarthritis. Thirty male Wistar rats [weight of 173 +/- 1 g, 8-weeks old] were randomly divided into 5 experimental groups [N=6]: intact control, MIA only, training, quercetin, training plus quercetin. The Osteoarthritis model was induced by intra-articular injection of monosodium iodoacetate [MIA]. Subjects then followed a moderate-intensity exercise program and quercetin supplementation for 28 days. Rats were killed after 28 days and histological assessment has been performed on their knee joints. One-way ANOVA [p<0.05] and post-hoc Tukey test was used for the statistical analysis. Histological assessment including 1- Depth Ratio of Lesions [p=0.001], 2- Total Degeneration Width [p=0.001] and 3- Significant Degeneration Width [p=0.001] demonstrated a beneficial influence of moderate exercise combined with quercetin supplementation group, but this influence was not superior than the moderate exercise alone group. This study shows that a moderate exercise program and quercetin supplementation, either alone or in combination, exert a beneficial influence on rats' knee osteoarthritis. But it appears that moderate exercise alone has more effectiveness
ABSTRACT
Ankle sprain is one of the most common injuries among athletes and Instability and injury to this joint is responsible for long time loss of physical and recreational activity. Also it can impose high cost to sport teams. Prevention of this injury is an important concern of practice and rehabilitation. One way of reducing the possibility of ankle joint injury is using ankle orthosis. The present study aimed at inspecting the effects of two ankle orthoses on dynamic and semi-dynamic postural stability in athletes with chronic ankle instability. [CAI] Twenty basketball players with CAI and fifteen non-injured athletes volunteered to participate in this study. Biodex Balance System was used to assess the participants' postural stability in bilateral position at level 8 and level 2. Repeated measures analyses variance [ANOVA] was performed in order to examine the effects of ankle orthoses. Statistical significance level was determined at P< 0.05. Statistical analyses revealed the significant effect of ankle supports on dynamic and semi-dynamic postural stability in the two groups and results indicated there wasn't significant difference between groups. According to our results the orthoses improved both dynamic and semi-dynamic postural stability. Therefore orthoses can prevent of injury and its reoccurrence
