The purpose of this study was to design shoe insoles for people with neck pain. In this study, elastic polymers and elastomers matrials were used to design the insole body. In the specific part, a polymer ring with emollient materials was used. Fifteen male students with neck pain were volunteered to participate in the present study. The pain intensity was measured after 120 mile walking with and without designed foot orthoses. Visual analog scale (VAS) index was used  for pain assessment. Shapiro-wilk test affirmed the normal distribution of the data. Paired sample t-test was used for statistical analysis using SPSS software version 26. A significant level of P≤0.05 was considered for all tests. The results of the present study showed that the designed insole reduced pain in people with neck pain (P=0.006). Overall, further studies were needed to better establish this issue.

Many annoying musculoskeletal pains and disorders are caused by the wrong habit and ‎ergonomics of the equipment in the workplace. Therefore, the aim of the present study was to ‎investigate the effect of eight weeks of corrective exercises, ergonomic recommendations on ‎the frequency of recurrent back pain due to musculoskeletal disorders in the staff of Ardabil ‎Youth and Sports Department‎.

The present study is applied and quasi-experimental. The statistical sample included 60 ‎employees of the Sports and Youth Department of Ardabil province who participated in this ‎study voluntarily. They were randomly divided into three equal groups of corrective exercises, ‎ergonomic recommendations and control. The Nordic questionnaire was used to collect the ‎frequency of musculoskeletal disorders in the lumbar region and the frequency of recurrence of ‎pain as a pre-test and post-test. Will Coxon test was used to compare data between groups using ‎SPSS software version 26. Also, a significant level (p≤0.05) was considered for all tests. Excel ‎‎2010 software was used to draw the chart‎.

The findings of the present study showed that there is a statistically significant difference ‎between the group of corrective exercises and ergonomic recommendations and the frequency ‎of recurrence of pain due to musculoskeletal disorders (P = 0.022). There was also a significant ‎difference between the correctional exercise group and the control group in the frequency of ‎recurrence of pain due to musculoskeletal disorders‏ ‏‎(P = 0.001)‎.

Providing corrective exercises significantly reduced the frequency of recurrence of pain due to musculoskeletal disorders in the lumbar region. Therefore, corrective exercises can be provided as useful and effective advice to reduce and eliminate the frequency of pain, especially to employees.

Scott training is one of the basic exercises in strengthening the lower limbs and also a factor to show a person's physical fitness. The aim of the present study was to compare the effect of strengthening the lumbar quadriceps muscle in increasing the record number of squats of male volleyball players in Ardabil province.

A total of 60 healthy volleyball athletes from Ardabil province were randomly divided into two equal groups of 30 intervention and control. Both groups were presented with the usual volleyball bodybuilding training method for 12 sessions, respectively, with strengthening the quadriceps muscle, as well as just the usual volleyball bodybuilding training. After 12 sessions, their record number of Scott moves was examined. Independent t-test was used to compare the groups's record number of squats using SPSS software version 26.

The findings of the present study showed that there is a statistically significant difference between the intervention group and the control one in the frequency of Scott's record of volleyball athletes (P≤0.001).

Providing reinforcement training increased Scott's record in the intervention group. Therefore, strengthening the lumbar quadriceps muscle can increase the frequency of Scott's record in male volleyball athletes in Ardabil province.
