Effect of proximal exercises of lower extremity on static balance parameters during quiet standing.

Purpose: People who suffer from knee osteoarthritis (KOA) face reduced balance, which causes increased falling and many serious complications and injuries. The purpose of the extant study was to determine the effect of proximal exercises of lower extremity on static balance parameters during quiet standing. Materials and Methods: In the present randomized controlled trial, 36 patients were divided into intervention and control groups (n = 18 in each group). Both groups received routine physiotherapy in three sessions per week for 6 weeks, while the intervention group did proximal exercises in addition to physiotherapy routine. In the extant study, the pain intensity was measured through a visual analog scale (VAS), and individuals' static balance parameters were measured using Biodex Balance System. All measurements were done before and after the intervention, and then statistical data analysis was performed with Statistical Package for the Social Sciences (SPSS) 24 software. Results: Intergroup comparison indicated significant progress of pain intensity, anterior-posterior (AP), and Overall balance stability in both studied groups (P < 0.05). There was a significant increase in medial-lateral (ML) balance stability only in the intervention group (P < 0.05). Intergroup comparison showed that there was not any significant difference between variables before the intervention (P > 0.05). The results showed more progress in the intervention group than the control group after they received the intervention, which was significant in terms of ML balance stability (P < 0.05). Conclusion: Adding proximal exercises to physiotherapy had more effect on ML balance stability in KOA patients; however, 6 weeks of these exercises in addition to physiotherapy had also the same effect on pain intensity, Overall, and AP balance stability.

The efficacy of physiotherapy interventions in mitigating the symptoms and complications of diabetic peripheral neuropathy: A systematic review.

PURPOSE: Diabetic peripheral neuropathy (DPN) leads to decreased sole sensation and balance disorder, all of which increase the risk of falls and socioeconomic costs. Since the physiotherapists do not use the same manner to lessen the complications of this problem. Therefore, this review study was directed to appraise physiotherapy intervention efficiencies in diminishing DPN's symptoms and complications. METHOD: A database search of Pubmed, Elsevier, Google Scholar, and Embase was performed to determine DPN's published documents. Finally, studies of DPN and treatments available in this field, particularly physiotherapy that included electrotherapy, exercise therapy, and other therapies, were identified. RESULT: According to a database search on August 1, 2019, from 1989 to 2019, in the last 30 years, about 968 articles were found, 345 of which were free full text available, and finally, 19 articles were approved. These articles examined the effects of physiotherapy interventions, including exercise therapy, electrotherapy, and other treatment techniques on DPN patients. CONCLUSIONS: The results showed that most diabetic peripheral neuropathy patients suffer from muscle weakness, pain, loss of balance, and lower limb dysfunction. As a result, their daily activity and Life satisfaction are gradually impaired. Exercise therapy, electrotherapy, and other physiotherapy methods have been used to reduce the mentioned cases. Among these interventions, exercise therapy has been the most effective. Although there was little evidence of aerobic exercise in these patients, further studies should be done on other therapies' effects.

Comparison of balance and stabilizing trainings on balance indices in patients suffering from nonspecific chronic low back pain.

The objective of the current research was to compare the impact of balance and stabilizing trainings on balance indices in patients with nonspecific chronic low back pain. In this randomized, controlled, single-blinded clinical trial, 20 people suffering from nonspecific chronic low back pain were randomly assigned to two groups of balance and stabilizing trainings. Trainings of both groups were performed for 6 weeks and four sessions per week. The overall, lateral, and anterior-posterior stability indices, pain, and disability were measured using Biodex balance system, visual analog scale, and Oswestry scale, before and after treatment, respectively. Paired t-test and independent t-test were used for analyzing the data. In the balance group, the pain severity was changed from 6.33 ± 1.63 to 4.33 ± 2.6 (P = 0.005) and dynamic anterior-posterior stability index in the standing position on left leg with closing eyes was changed from 5.56 ± 2.25 to 3.45 ± 1. 57 (P = 0.03). In the stabilizing group, pain severity was changed from 4. 16 ± 1.47 to 1.33 ± 0.81 (P = 0.0001) and disability index was changed from 17.33 ± 5.60 to 5.33 ± 3.93 (P = 0.01). Reduction in pain and disability in the stabilizing group and increase in two balance indices were significant in the balance training group compared to those in other group (P < 0.05). Research findings revealed that the impact of stabilizing trainings was significant in reducing pain and disability compared to that in balance trainings.

The Effect of Stabilization Exercises on Pain, Disability, and Pelvic Floor Muscle Function in Postpartum Lumbopelvic Pain: A Randomized Controlled Trial.

OBJECTIVE: The effect of stabilization exercises on pain, disability, and pelvic floor muscle function in postpartum lumbopelvic pain. DESIGN: This is a single-blind, randomized controlled trial. SETTING: This study was performed at the physiotherapy clinic, Zahedan University of Medical Science, from January to November 2017. PARTICIPANTS: Thirty-six multiparous women with persistent postpartum lumbopelvic pain were recruited at least 3 mos after delivery. INTERVENTIONS: Subjects in the training group (n = 18) received electrotherapy modalities and specific stabilizing exercises. The control group (n = 18) received only electrotherapy modalities. MAIN OUTCOME MEASURES: Pain, disability, and bladder base displacement (at rest and pelvic floor muscles contraction) were measured through visual analog scale, Oswestry Disability Index questionnaires, and transabdominal ultrasound imaging respectively at baseline and after 6 wks of intervention. RESULTS: Between-groups comparison showed significant improvement in pain, disability, and bladder base displacement in the training group (P < 0.05). In within-group comparison, training group had significant difference for all variables (P < 0.05). In the control group, pain and disability had significant difference (P < 0.05), whereas bladder base displacement had no significant change (P < 0.05). CONCLUSIONS: The stabilizing exercises can remarkably improve pain, disability, and pelvic floor muscles function in postpartum lumbopelvic pain (Clinical Trial Registry: NCT03030846).

The Effects of Balance Training on Static and Dynamic Postural Stability Indices After Acute ACL Reconstruction.

BACKGROUND: Proprioception and postural stability play an important role in knee movements. However, there are controversies about the overall recovery time of proprioception following knee surgery and onset of balance and neuromuscular training after ACL reconstruction. Therefore, it is necessary to evaluate the effect of balance training in early stage of knee rehabilitation after anterior cruciate ligament (ACL) reconstruction. The purpose of this study was to evaluate the effect of balance exercises on postural stability indices in subjects with anterior cruciate ligament (ACL) reconstruction. METHODS: The study was a controlled randomized trial study. Twenty four patients who had ACL reconstructed (balance training group) and twenty four healthy adults without any knee injury (control group) were recruited in the study. The balance exercises group performed balance exercises for 2 weeks. Before and after the interventions, overall, anteroposterior, and mediolateral stability indices were measured with a Biodex Balance System in bilateral and unilateral stance positions with the eyes open and closed. T-tests were used for statistical analysis (p<0.05). RESULTS: Results showed that amount of static stability indices did not change after training and there were not significant differences in static stability indices before and after balance training (p>0.05). Although amount of dynamic stability indices decreased, there were not significant differences in dynamic stability indices before and after balance training (p>0.05). Amount of dynamic stability indices were decreased in balance training group, however, there were not significant differences between groups (p>0.05). CONCLUSION: These results support that balance exercise could partially improved dynamic stability indices in early stage of ACL reconstruction rehabilitation. The results of this study suggest that balance exercises should be part of the rehabilitation program following ACL reconstruction.

Intra-Rater Reliability of Rehabilitative Ultrasound Imaging for Multifidus Muscles Thickness and Cross Section Area in Healthy Subjects.

INTRODUCTION: Rehabilitative Ultrasound Imaging (RUSI) must be valuable method for research and rehabilitation. So, the reliability of its measurements must be determined. The purpose of this study was to evaluate the intra-rater reliability of RUSI for measurement of multifidus (MF) muscles cross section areas (CSAs), bladder wall diameter, and thickness of MF muscles between 2 sessions in healthy subjects. METHOD: Fifteen healthy subjects through simple non-probability sampling participated in this single-group repeated-measures reliability study. MF muscles thickness at rest and during contraction, MF muscles CSAs at rest, and bladder diameters at rest and during pelvic floor muscles (PFM) contraction were measured through RUSI. Pearson's correlation coefficient test was used to determine intra-rater reliability of variables. FINDING: The results showed that intra-class correlation Coefficient (ICCs) values with 95% confidence interval (CI) and the standard error of the measurement (SEM) were good to excellent agreement for a single investigator between measurement occasions. The intra-rater reliability for the bladder wall displacement was high (ICCs for rest and PFM contraction state: 0.96 and 0.95 respectively), for the MF muscles CSAs at the L4 level was good to high (ICCs 0.75 and 0.91 for right (Rt) and left (Lt) side respectively), and for the thickness of MF muscles at two levels, at rest and during two tasks was moderate to high (ICCs: 0.64 to 0.87). CONCLUSION: The Trans-Abdominal (TA) method of RUSI is a reliable method to quantify the PFM contraction in healthy subjects. Also, the RUSI is a reliable method to measure the MF muscles CSAs, the MF muscles thickness at rest and during functional tasks in healthy subjects.

The Effects of Stabilization and Mckenzie Exercises on Transverse Abdominis and Multifidus Muscle Thickness, Pain, and Disability: A Randomized Controlled Trial in NonSpecific Chronic Low Back Pain.

[Purpose] This study compared the effectiveness of stabilization and McKenzie exercises on pain, disability, and thickness of the transverse abdominis and multifidus muscles in patients with nonspecific chronic low back pain. [Subjects] Thirty patients were randomly assigned into two groups: the McKenzie and stabilization exercise groups. [Methods] Before and after intervention, pain, disability, and thickness of the transverse abdominis and multifidus muscles were evaluated by visual analogue scale, functional rating index, and sonography, respectively. The training program was 18 scheduled sessions of individual training for both groups. [Results] After interventions, the pain score decreased in both groups. The disability score decreased only in the stabilization group. The thickness of the left multifidus was significantly increased during resting and contracting states in the stabilization group. The thickness of the right transverse abdominis during the abdominal draw-in maneuver, and thickness of the left transverse abdominis during the active straight leg raising maneuver were significantly increased in the stabilization group. The intensity of pain, disability score, thickness of the right transverse abdominis during the abdominal draw-in manouver, and thickness of the left transverse abdominis during active straight leg raising in the stabilization group were greater than those on the Mackenzie. [Conclusion] Stabilization exercises are more effective than McKenzie exercises in improving the intensity of pain and function score and in increasing the thickness of the transverse abdominis muscle.
