Background & Aim:

Low back pain refers to a pain felt in the lumbar and sacrum regions of the spine. The aim of this study was to investigate the effect of movement pattern exercises on plantar pressure variables in people with chronic low back pain during walking.

Materials & Methods:

The present study was a quasi-experimental study with a pre-test and post-test design along with a control group. The study subjects, who were selected from the clients of the health and wellness center of Mohaghegh Ardabili University, Ardabil, Iran, were randomly divided into 10 people with chronic back pain (experimental group) and 10 people with back pain (control group). The subjects of the experimental group performed movement pattern exercises for 6 weeks, but the control group did not perform any exercises during this period of 6 weeks. Plantar pressure values were recorded during pre-test and post-test by foot scan device (sampling rate: 300 Hz). Two-way analysis of variance was used for statistical analysis of data. All analysis was done at significant level of 0.05 with SPSS 22 software.

Results showed that the peak of the vertical component at the heel contact (p = 0.009) and the vertical loading rate (p = 0.013) in the experimental group during post-test was lower compared to the pre-test. Pairwise comparison showed that the peak force in the second metatarsal bone in the experimental group was lower in the post-test compared to the pre-test (p=0.018).

Low back pain is one of the most common musculoskeletal disorders in athletics. The aim of this study was to determine the effect of Movement-Pattern Training on the range of motion of the knee joint in the frontal level in athletes with nonspecific chronic low back pain during sing-leg landing.

This clinical trial was carried out in University of Mohaghegh Ardabili at 2018. Firstly, 30 males with non-specific chronic low back pain were selected with available sampling and then they randomly divided into control (15 subjects) and experimental (15 subjects) groups. Tests were done in the form of pre and post-tests. Movement pattern exercises were performed on experimental group over a 6-week period. Ethically, the training protocol was done on waiting control group after post-test. Post hok Co-variance was used for statistical analysis of data.

The results showed that movement pattern training reduces the range of motion of the knee joint in the frontal level of patients with non-specific chronic low back pain (P=0.000, d=3.94 high effect size).

The results of the study showed that the exercises of the movement pattern have caused significant changes in the range of motion of the knee joint at the frontal level. that could be beneficial for future researches in order to prevent and treat the low back pain individuals.

The scientific evidence related to the effectiveness of rehabilitation on electromyographical activity of trunk muscles is limited. This study was performed to determine the effect of movement-pattern training on frequency of selected trunk muscles during single-leg landing in individuals with non-specific chronic low back pain.

In this clinical trial study, 28 patients with non-specific chronic low back pain were randomly divided into intervention and control groups. The control group did not receive treatment. The intervention group performed treatment as a movement-pattern training. Subjects performed single leg landing from 30 cm height. Trunk muscle activity was assessed using an 8-chanel EMG system. The assessments were completed in pre-test and after six weeks.

Frequency content of right rectus abdominus and right lumbar erector spinae in intervention group were lower than control group (P<0.05). In other muscles ant there was not any significant significant differences between interventional and control groups.

The movement-pattern training can be used in rehabilitation of individuals with non-specific chronic low back pain.

Abnormal hip kinematic and impaired hip muscle performance have been associated with various musculoskeletal disorders, such as patellofemoral pain, ligaments injuries, low back pain, and hip joint pathology. Therefore, the aim of this study was to determine the effect of movement-pattern training on selected landing kinematic variables in athletes with non-specific chronic low back pain.

This clinical trial was carried out at the University of Mohaghegh Ardabili at 2018. Firstly, 30 males with non-specific chronic low back pain were selected by available sampling and randomly divided into the control (15 subjects) and experimental (15 subjects) groups. Tests were done in the form of pre and post-tests. Movement pattern exercises were performed on the experimental group over a 6-week period. Ethically, the training protocol was done on the control group after the post-test. ANCOVA test was used for statistical analysis of data.

The results showed that movement pattern exercises improved (increase) the kinematic variables in patients with chronic non-specific low back pain (p=0.001).

Findings demonstrated that implementation of movement pattern exercises significantly altered kinematic variables that could be beneficial for future researches in order to prevent and treat individuals with low back pain.
