Effects of aquatic exercises in patients after total hip arthroplasty: A systematic review.

BACKGROUND: Total hip arthroplasty (THA) is a surgical procedure that can alter physical function and quality of life. OBJECTIVES: The aim was to verify the effects of aquatic exercises compared with exercises on land, control or other modalities, in patients undergoing THA on the primary outcomes: self-reported physical function, quality of life and pain; and secondary outcomes: muscle strength, functional capacity and gait. DESIGN: Systematic review that followed the PRISMA Statement and PROSPERO registered. The search was performed in the following databases: Web of Science, Embase, Medline, Cinahl, Lilacs, SPORTDiscus, Cochrane Library, Scopus, SciELO, and PEDro, from 1945 to 2022. The risk of bias assessment was performed using the Risk of Bias 2 (RoB2) from the Cochrane Collaboration. RESULTS: Three randomized controlled trials (RCTs) were included, with a total of 364 participants. In the selection process, two publications from the same study were found. The RoB2 assessment classified one RCT as "high risk of bias" and the others as "low risk of bias". Therefore, the analysis of the results considered only studies with a low risk of bias. For the self-reported physical function outcome, evaluated by WOMAC, improvement was observed in favor of aquatic exercises, when started on the 14th postoperative day. Pain improved after 24th week postoperative, in favor of exercise (effect size between 0.2 and 0.4). Quality of life, verified only by one RCT, improved at each time point evaluated (effect size between 0.01 and 0.10). The functional capacity showed no difference between the groups. This was the first systematic review to assess the benefits of aquatic exercises specifically in THA and it was possible to infer that the exercises initiated after 14 days of postoperative are safer. The protocol should include proprioceptive, coordination, and resistance exercises. The session can last around 30 min and is held three times a week. CONCLUSION: Decision making for treatment in the postoperative of THA may include aquatic exercises as a safe and efficacious alternative to improve self-reported physical function, pain, quality of life, and muscle resistance.

Non-radiographic validity and reliability measures for assessing foot types: A systematic review.

BACKGROUND: Foot type classification is well recognized in clinical practice and orthopedic literature, a universally accepted classification or standardized measures to determine foot types are lacking. The objective of this study was to identify which non-radiographic assessment methods are considered valid and/or reliable for the classification of foot types. METHOD: A systematic database search was performed. Only cross-sectional studies that performed reliability and/or validity analysis of non-radiographic methods were included. To evaluate the risk of bias, the Critical Appraisal Tool (CAT) was used to evaluate the measurement properties of objective clinical methods. RESULTS: Twenty-six studies were included. The results of reliability and validity, in general, demonstrated high scores, but, inconsistencies were related to the variability of the measurements, heterogeneity of the methods used to determine reliability and validity, and lack of parameters for classifying foot types, which resulted in few elements to determine which method of foot type evaluation is valid and reliable. CONCLUSION: Given the Intraclass Correlation Coefficient and CAT results and the presence of normative values, the static measurements of the "Arch Height Index", "Foot Posture Index", and "Staheli Arch Index" can be suggested to classify foot types.

Diagnostic ability of Barrett's index to detect dysthyroid optic neuropathy using multidetector computed tomography.

OBJECTIVES: The objective of this study was to evaluate the ability of a muscular index (Barrett's Index), calculated with multidetector computed tomography, to detect dysthyroid optic neuropathy in patients with Graves' orbitopathy. METHODS: Thirty-six patients with Graves' orbitopathy were prospectively studied and submitted to neuro-ophthalmic evaluation and multidetector computed tomography scans of the orbits. Orbits were divided into two groups: those with and without dysthyroid optic neuropathy. Barrett's index was calculated as the percentage of the orbit occupied by muscles. Sensitivity and specificity were determined for several index values. RESULTS: Sixty-four orbits (19 with and 45 without dysthyroid optic neuropathy) met the inclusion criteria for the study. The mean Barrett's index values (+/- SD) were 64.47% +/- 6.06% and 49.44% +/- 10.94%in the groups with and without dysthyroid optic neuropathy, respectively (p<0.001). Barrett's index sensitivity ranged from 32% to 100%, and Barrett's index specificity ranged from 24% to 100%. The best combination of sensitivity and specificity was 79%/72% for BI=60% (odds ratio: 9.2). CONCLUSIONS: Barrett's Index is a useful indicator of dysthyroid optic neuropathy and may contribute to early diagnosis and treatment. Patients with a Barrett's index >60% should be carefully examined and followed for the development of dysthyroid optic neuropathy.

Diagnostic ability of barrett's index to detect dysthyroid optic neuropathy using multidetector computed tomography

Sensitivity and specificity were determined for several index values. RESULTS: Sixty-four orbits (19 with and 45 without dysthyroid optic neuropathy) met the inclusion criteria for the study. The mean Barrett's index values (± SD) were 64.47 percent ± 6.06 percent and 49.44 percent ± 10.94 percentin the groups with and without dysthyroid optic neuropathy, respectively (p<0.001). Barrett's index sensitivity ranged from 32 percent to 100 percent, and Barrett's index specificity ranged from 24 percent to 100 percent. The best combination of sensitivity and specificity was 79 percent/72 percent for BI=60 percent (odds ratio: 9.2). CONCLUSIONS: Barrett's Index is a useful indicator of dysthyroid optic neuropathy and may contribute to early diagnosis and treatment. Patients with a Barrett's index >60 percent should be carefully examined and followed for the development of dysthyroid optic neuropathy.
