[Purpose] The purpose of this review is to compare the effect of McKenzie and stabilization exercises in reducing pain and disability in individuals with chronic nonspecific low back pain. [Methods] A systematic literature review of randomized controlled trials (RCTs) were performed using 6 databases. The quality of reviewed articles were assessed by the risk of bias using the Cochrane collaboration’s tool. [Results] A total of 829 articles were found from the databases, of which 10 were finally selected to be included in this review. The overall risk of bias assessment indicated that the risk of bias was low in one study and high in the other nine studies. One study reported reduced pain and two studies reported reduced functional disability in the McKenzie exercise group compared to other exercises. Two studies reported reduced pain and three studies reported reduced functional disability in the stabilization exercise group compared to other exercises. In two studies, the stabilization exercise group was as effective as McKenzie exercise group in reducing pain and functional disability in patients with chronic nonspecific low back pain. [Conclusion] Only two studies compared stabilization and McKenzie exercises in the management of chronic nonspecific low back pain. Therefore, insufficient evidence is available to draw any conclusive comparison on the effects of McKenzie and stabilization exercises in chronic nonspecific low back pain. However, both McKenzie and stabilization exercises was better than conventional exercise programs in reducing functional disability in patients with chronic nonspecific low back pain.
Constraint-induced movement therapy (CIMT) is one of the most popular treatments for enhancing upper and lower extremity motor activities and participation in patients following a stroke. However, the effect of CIMT on balance is unclear and needs further clarification. The aim of this research was to estimate the effect of CIMT on balance and functional mobility in patients after stroke. After reviewing 161 studies from search engines including Google Scholar, EBSCO, PubMed, PEDro, Science Direct, Scopus, and Web of Science, we included eight randomized controlled trials (RCT) in this study. The methodological quality of the included RCTs was verified using PEDro scoring. This systematic review showed positive effects of CIMT on balance in three studies and similar effects in five studies when compared to the control interventions such as neuro developmental treatment, modified forced-use therapy and conventional physical therapy. Furthermore, a meta-analysis indicated a statistically significant effect size by a standardized mean difference of 0.51 (P = 0.01), showing that the groups who received CIMT had improved more than the control groups. However, the meta-analysis results for functional mobility were statistically insignificant, with an effect size of −4.18 (P = 0.16), indicating that the functional mobility improvements in the investigated groups were not greater than the control group. This study’s findings demonstrated the superior effects of CIMT on balance; however, the effect size analysis of functional mobility was statistically insignificant. These findings indicate that CIMT interventions can improve balance-related motor function better than neuro developmental treatment, modified forced-use therapy and conventional physical therapy in patients after a stroke.
Background: Football is a commonly played team sport, and kicking is the primary skill needed. The incidence of adductor strain is high in football players, and thus their kick distance is affected due to groin pain. This indicates the importance of stretching and strengthening exercises as a necessary therapeutic technique to treat these sportspeople. Objective: To compare the effectiveness of muscle energy techniques (MET), stretching and strengthening exercises on hip rotation, and kick distance. Design: Randomized Control Trial. Methods: Forty football players suffering from groin pain due to adductor strain were selected from five professional soccer clubs in Jazan, Saudi Arabia, and randomized into two equal groups. Affected hip joint rotation [Internal + External Rotation] range, instep kick, and sidekick distances were measured and documented as baseline values. In addition, group A received MET, stretching, and strengthening exercises, whereas group B received only stretching and strengthening exercises for six weeks. Post-test values of the outcome measures were recorded at the end of the intervention. Results: Statistical comparison of the results between the groups showed that the MET group had significant improvement than the strengthening and stretching group in the hip rotation range (p<0.005), but the difference was not significant for both in-step kick and front kick distance (p<0.0001). Conclusion: Thus, adding MET to the routine strengthening and stretching exercise regimen can be clinically beneficial in treating groin pain among football players.
Dysmenorrhea is the term for describing complex menstrual flow and painful spasmodic cramps during menstruation, and pain without any pathology is considered Primary Dysmenorrhea (PD). It is the most frequent ailment among women of all ages and races. The pain is dull and throbbing in character and occurs in the lower back and abdomen. Symptoms commonly appear 6 to 12 months after menarche, with the most significant incidence in the late teen and early twenties. Physical exercise is nearly a new non-medical intervention to relieve PD associated pain. Aerobics, stretching and Resistive exercises for 8-12 weeks, either supervised or unsupervised, relieves pain. Exercises are believed to cause hormonal changes in the uterine lining, which reduces PD symptoms. Researchers have presumed different pain-relieving methods, ranging from non-opioids to opioids to hormonal for variations in pain sensitivity. Exercise-induced analgesia provides the central pathway as the primary mechanism for pain reduction while, another way to reducing pain in PD may be a hormonal interaction. The hormonal changes causing exercise-induced pain modulation during the menstruation cycle is not clearly understood and the interaction and activation of all the central and endocrine components, which is a complex mechanism, is also not explained clearly. This study briefly reviews the physiological mechanism of Exercise-induced analgesia and its potent roles in controlling the pathogenesis of PD for pain relief.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
