“…However, these reference data correspond to subjects with CLBP, and were obtained from reviews in which no assessment of the quality of the evidence was carried out. This could limit our confidence in the reported data [ 31 , 32 ]. Furthermore, in CLBP, the evidence shows that pain and disability do have physical causes and have multifactorial etiology [ 33 ], with psychological factors [ 34 ], central sensitization [ 35 ] and kinesiophobia [ 36 ] playing a role in this type of patient.…”

Background: The purpose of this systematic review was to: (I) determine the quality of evidence from studies assessing trunk isokinetic strength in subjects with acute low back pain (ALBP) compared to healthy subjects and (II) establish reference values of isokinetic trunk strength in subjects with ALBP. Methodology: Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) statements were followed using keywords associated with trunk, strength and low back pain. Four databases were used: PubMed, Web of Science, Scopus and SPORTDiscus. Methodological quality was assessed using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS). Results: A total of 1604 articles were retrieved, four included in this review. All were evaluated as high risk of bias (Rob). Due to the high Rob and the diversity of protocols, instruments and variables used, it was not possible to determine reference values for subjects with ALBP, we can only establish a range of flexion peak torque (PT) between 175.1 and 89.7 Nm at 60°/s and between 185 and 81.5 Nm at 120°/s, and for extension PT between 240.0 and 91.5 Nm at 60°/s and between 217.5 and 69.2 Nm at 120°/s in subjects with ALBP. Conclusions: Due to the low quality of the evidence and the diversity of protocols used when measuring trunk isokinetic strength, it is necessary to carry out new high-quality research to establish reference values of trunk strength in subjects with ALBP.

“…To quantify pathological changes and to monitor disease progression in myopathies, quantitative MRI (qMRI) technique is superior to visual rating scales to show change (3,4). Quantitative strength assessment of the lower limb muscles and the muscles of the trunk using Biodex has been established to be a reliable method in previous studies (5,6). With this 1-year follow-up study, we wish to gain knowledge on how axial muscle involvement progresses over time in BMD using quantitative muscle MRI.…”

Quantitative Muscle MRI as Outcome Measure in Patients With Becker Muscular Dystrophy—A 1-Year Follow-Up Study

Introduction: With the advent of emerging molecular therapies for muscular dystrophies, the need for knowledge about natural history course of such diseases is of utmost importance in the preparation for future trials. However, for Becker muscular dystrophy such knowledge is scarce.Objective: In this 1-year follow-up study, we examined disease progression in Becker muscular dystrophy by monitoring changes in MRI-assessed muscle fat fraction (FF) in axial and lower limb muscles and quantitative muscle strength of axial muscles.Methods and Materials: Sixteen patients with Becker muscular dystrophy were investigated by (1) muscle strength of the trunk using a Biodex dynamometer and (2) Dixon muscle MRI of paraspinal and lower limb muscles. Quantitative MRI data was analyzed in two parts: The first part consisted of all participants (N = 16). The second analysis assessed two separate groups comprising lesser affected participants (N = 5) and more severely affected patients (n = 11).Results: Trunk extension and flexion strength remained stable from baseline to follow-up. MRI did not show any significant increase in muscle FF % from baseline to follow-up in all patients, except for multifidus at the spinal level T12 (p = 0.01). However, when we analyzed the two subgroups, according to disease severity, FF% increased in the lesser severely affected group at L4/L5 erector spinae (p = 0.047), sartorius (p = 0.028), gracilis (p = 0.009), tibialis anterior (p = 0.047), peroneals (p = 0.028), and gastrocnemius medialis (p = 0.009), while the severely affected group only increased significantly at T12 multifidus (p = 0.028) and T12 erector spinae (p = 0.011). No difference in muscle strength was observed in the two subgroups.Conclusion: Our results add to the existing knowledge about the natural rate of disease progression in BMD. As quantitative MRI was able to identify changes where strength assessment was not, MRI could be a strong biomarker for change in BMD. However, our findings show that it is important to stratify patients with BMD according to phenotype for future clinical trials.

“…Recent studies have associated discomfort due to pain with several factors [ 5 ] such as age [ 6 , 7 , 8 ], sex [ 6 , 9 ], sexual activity [ 10 ], sleep [ 11 ], and body mass index (BMI) [ 12 ]. Additionally, back pain affects the formation of structures in the lumbar region [ 13 , 14 ] and causes knee [ 15 ] and shoulder [ 16 ] pain during high impact sports [ 17 , 18 ]. Thus, it has been studied for several sports such as rowing, rugby, football, fighting, and gymnastics [ 19 , 20 , 21 , 22 , 23 , 24 ].…”

Evaluation Instruments for Assessing Back Pain in Athletes: A Systematic Review Protocol

et al. 2020

View full text Add to dashboard Cite

Back pain is a public health problem that affects adolescents and adults worldwide. However, studies on back pain present inconsistent findings in part due to the use of different instruments, especially for athletes. Therefore, the objective of this systematic review protocol was to map the existing evidence on such tools. The systematic review will be conducted according to PRISMA guidelines. Five electronic databases, Embase, MEDLINE, SPORTDiscus, CINAHL, and Scopus will be searched. This review includes studies that investigated prevalence, incidence, and other variables. Titles and abstracts will be selected. Two independent reviewers will read the articles carefully and discrepancies, if any, will be dealt with by a third reviewer. All steps will be completed with Rayyan for systematic reviews and the methodological quality will be analyzed with a COSMIN checklist. Discussion: This systematic review will gather evidence on tools that assess back pain in athletes. The findings may indicate the most appropriate tools for assessing back pain. They will contribute to better reliability, safe measurements, and help to standardize a comparison tool between different studies. They will also assist in the development of specific tools for athletes. Registration: This review was submitted and registered under CRD42020201299 in PROSPERO.
