Outcome of 24 Weeks of Combined Schroth and Pilates Exercises on Cobb Angle, Angle of Trunk Rotation, Chest Expansion, Flexibility and Quality of Life in Adolescents with Idiopathic Scoliosis.
BACKGROUND This study aimed to quantify the outcomes of combining Schroth and Pilates exercises on the Cobb angle, angle of trunk rotation (ATR), chest expansion, flexibility (trunk flexion), and quality of life (QoL) in adolescents with mild and moderate idiopathic scoliosis. MATERIAL AND METHODS Sixty-nine adolescents with idiopathic scoliosis aged 10-17 years, presenting with a Cobb angle of 10-45º were enrolled in this study. The treatment protocol, including selected exercises from Schroth and Pilates methods, was performed over 24 weeks and consisted of 2 periods of 2-week treatment regimens performed daily for 60 minutes. Each of treatment periods was then followed by the same home program treatment for 10 weeks. Cobb angle (x-rays), ATR (Scoliometer), chest expansion (cm), trunk flexion (cm, distance between C7 to S2 with measuring tape), and QoL (SRS-22r Scoliosis Research Society Questionnaire) were assessed pre-treatment, at 12 week, and at 24 weeks. RESULTS Significant improvements (P<0.05) were found in both groups of patients wearing and not wearing a brace for Cobb angle (from 21.97±4.99° to 18.11±6.39°; from 14.19±3.11° to 11.66±2.73°), angle of trunk rotation (from 7.19±1.36° to 5.36±1.66°; from 4.72±1.04° to 3.58±0.94°), chest expansion (from 2.56±0.84 cm to 3.46±0.72 cm; from 2.57±0.87 cm to 3.52±0.72 cm), trunk flexion (from 9.55±1.95 cm to 14.33±2.40 cm; from 9.82±2.61 cm to 13.98±2.18 cm) and QoL (from 3.50±0.27 to 3.82±0.2; from 3.42±0.24 to 3.78±0.23) respectively. CONCLUSIONS This study showed that combined exercises provided benefit on the Cobb angle, ATR, chest expansion, trunk flexion and QoL in adolescents with mild and moderate idiopathic scoliosis.

BACKGROUND
Embolization coils have routinely been used to treat intracranial aneurysms via an endovascular approach. Soft coils are typically viewed as the best design for filling and finishing the aneurysms to achieve a higher packing density and are hypothesized to exert a lower force against the aneurysm wall during deployment. We report here an in vitro pliability test method to assess clinically relevant coil softness and compare these metrics for two commercially available framing and finishing coil products.
METHODS
A force measurement sensor was affixed onto a side-wall synthetic aneurysm model to continuously measure forces on the aneurysm wall during coil deployment at a fixed delivery rate. A quantitative overall energy metric (average work number or AWN) was calculated from the force-displacement graph representing coil delivery into the aneurysm. Two groups of coils were evaluated: (a) finish coil group (N = 20 ea.): Axium™ Prime Extra Soft coil (ES) and Target™ 360 Nano coil (Nano), and (b) frame coil group (N = 20 ea.): Axium™ Prime FC coil (FC) and Target™ 360 Standard coil (Standard).
RESULTS
(a) In the finish coil group, AWN was measured as: ES (0.53 ± 0.09 gf-cm) and Nano (0.99 ± 0.21 gf-cm). (b) In the frame coil group, AWN was measured as FC (2.54 ± 0.53 gf-cm) and Standard (4.48 ± 0.52 gf-cm). In both groups, Axium Prime coils had statistically lower measures of AWN and therefore higher pliability compared to Target coils (p < .001).
CONCLUSIONS
The in-vitro pliability test method offers quantitative metrics to assess coil softness during deployment in a clinically relevant aneurysm model.

Meta-Analysis
People with multiple sclerosis (MS) often experience limitations in joint range of motion, which is linked to spasticity and continued inactivity. Low flexibility levels in this population have been linked to postural problems and muscular pain. Therefore, the purpose of this study was to conduct a systematic review and a meta-analysis aimed at identifying the characteristics and methodological quality of investigations studying the effects of exercise interventions on the flexibility levels of people with MS. Three electronic databases (MEDLINE/PubMed, SPORTDiscus and Scopus) were systematically searched up to May 2019 for intervention studies focused on the effects of exercise on the flexibility levels of people with MS. A meta-analysis, including randomized controlled trials (RCT), which reported information regarding the effects of exercise on flexibility, was also conducted. The methodological quality of included studies was assessed using the Physiotherapy Evidence Database, and the Quality Assessment Tool for Before-After Studies, with no control group. The quality of the information reported, regarding the programs conducted, was assessed by means of the Consensus on Exercise Reporting Template (CERT) scale. Seven studies, four RCTs and three uncontrolled investigations were finally selected. The methodological quality of the RCTs was considered "poor" in one study, and "good" and "excellent" in two studies and one investigation, respectively. The three uncontrolled studies showed a methodological quality between "fair" and "poor". Following the CERT scale, four studies were graded as "high" and three as "low". Findings from the meta-analysis indicated no significant effects on hamstring flexibility, or the range of motion in the hips, knees or ankles. There is preliminary evidence from individual studies which indicates that people with MS can improve their lower limb flexibility following participation in physical exercise programs, but the meta-analysis did not confirm these findings.

OBJECTIVES
To quantitatively evaluate the effect of vocal fold lengthening on pliability of the mucosa measured along the superior-inferior axis and to examine the relation of the location of mucosal upheaval (MU) during phonation to the changes in pliability pattern of the mucosa when the vocal fold was lengthened.
DESIGN
Investigation of mechanical characteristics of the vocal fold in relation to the MU during phonation.
MATERIALS
Five excised canine larynges.
INTERVENTIONS
Vibrations with and without vocal fold lengthening were recorded from the tracheal side via high-speed photography or video recording combined with stroboscopic illumination. Tattooed marks on the lower surface of the vocal fold were used to locate the MU. Pliability was defined as the maximal distance elevated in response to a constant focal negative pressure.
RESULTS
Pliability decreased significantly (P=.05) when the vocal fold was lengthened. The point of minimal pliability and MU without vocal fold lengthening were located slightly above the area where the muscular layer approached the epithelial layer. They were located closer to the free edge of the vocal fold when it was lengthened than when it was not. Discrepancy of their locations when the vocal fold was lengthened was suggested.
CONCLUSIONS
The MU occurs around the point of minimal pliability when the vocal fold is not lengthened, whereas the MU occurs slightly more laterally than the point of minimal pliability when the vocal fold is lengthened. Although further study is necessary to explain this discrepancy, the presence of the sparse deep layer of the lamina propria seems to be essential in the generation of the mucosal wave.

INTRODUCTION
The cardiac catheter is an intravascular catheter, which is introduced or implanted into the heart for diagnostic or therapeutic reasons. The catheters may break or king during their introduction and/or removal.
AIM
The aim of the authors was to study the pliability of two catheters with the same material but different diameters according to the Food and Drug Administration's recommendation.
METHOD
The bending points, diameter decrease, deflection, and their correlation and dependence on the distance from the tip, as well as the influence of the initial diameter of the catheters were determined. The bending of catheters was performed on 9 bending points (120-280 mm from the tip by 20 mm) on 16 gauges with different radius (10-2.5 mm by 0.5 mm).
RESULTS
A linear dependency between the diameter decrease and deflection was observed, which was independent from the placement of the measurement in both catheters examined. The larger initial diameter had significant (p = 0.05) greater diameter decrease than the smaller, but the curves characteristic of the diameter decrease and deflection were similar.
CONCLUSIONS
The applied method seems to be useful for the examination of weak points of cardiac catheters.
