Pain perception and stabilometric parameters in people with chronic low back pain after a pilates exercise program: A randomized controlled trial
Various exercise interventions, such as Pilates exercises and traditional physical therapy methods, are employed to decrease low back pain (LBP). Nonspecific low back pain (NSLBP) is distinct from LBP, however, as the distribution of pain is restricted to the region between the costal margin and the inferior gluteal. The aim of our randomized controlled trial was to evaluate the effects of a program of Pilates exercises on pain perception and stabilometric parameters in patients with NSLBP.Thirty-eight participants were randomly allocated, using a 1:1 scheme, to either the experimental group (EG) or control group (CG). The EG completed a 14-week program of Pilates exercises, performed thrice per week under the supervision of an exercise specialist, while the CG was managed with a social program only. Measures of posturography and Oswestry Disability Index (ODI) for pain perception were obtained at baseline (T0) and after the 14 weeks of intervention (T)1.Posturography measures improved for patients in the EG, with both eyes open and eyes closed (P\u200a<\u200a0.05). There were no statistical differences in posturography in the CG. ODI decreased significantly in both groups over the 14 weeks of the study protocol: EG, T0, 13.7\u200a\ub1\u200a5.0 compared with T1, 6.5\u200a\ub1\u200a4.0 (P\u200a<\u200a0.001); and CG, T0, 10.7\u200a\ub1\u200a7.8 compared with T1, 8.4\u200a\ub1\u200a7.8 (P\u200a<\u200a0.01). A greater extent of reduction in pain was achieved in the EG.The Pilates exercise program yielded improvements in pain and posturography outcomes. Our study also confirms the applicability of posturography in evaluating postural instability in patients with NSLBP. Due to our relatively small study group, future studies would be necessary to confirm our findings
Observational study of sleep-related disorders in Italian patients with Parkinson's disease: usefulness of the Italian version of Parkinson's disease sleep scale.
Sleep disturbances are common in patients with Parkinson's disease (PD). We aimed to evaluate prevalence and severity of nighttime sleep disturbances in Italian PD patients and to validate the Italian version of the Parkinson's disease sleep scale. A total of 221 PD patients and 57 healthy controls participated in a cross-sectional study with retest. PDSS, Epworth Sleepiness Scale (ESS), Hamilton Depression Rating Scale, Unified Parkinson's Disease Rating Scale (UPDRS), and Hoehn and Yahr staging were applied. PDSS total and individual items scores from patients were significantly lower than those in controls. Internal consistency of PDSS scale was satisfactory and intraclass correlation coefficient for test-retest reliability was 0.96 for total PDSS score. A significant negative correlation was found between total PDSS and ESS scores, and between total PDSS and HDRS scores. PDSS scores were also related to UPDRS sections II, III and IV, and H&Y stage. PDSS and ESS scores were not related to levodopa equivalent dose. Daytime sleepiness, depressive symptoms and disease severity correlate with sleep disturbances in Italian PD patients. The PDSS is a valid and reliable tool to evaluate sleep disturbances in Italian patients. © 2011 Springer-Verlag
EFFECTS OF A SPECIFIC TRAINING PROTOCOL ON POSTUROGRAPHIC PARAMETERS OF A TAEKWONDO ELITE ATHLETE AND IMPLICATIONS ON INJURY PREVENTION: A CASE STUDY
Introduction: Taekwondo elite athletes should have excellent qualities in several aspects of fitness, as well as peculiar postural
characteristics in terms of balance and postural control, to achieve the best possible results during competitions. Moreover,
it is known that taekwondo shows high risk of injury. The aim of this case study is to evaluate the effects of a specific training protocol
on posturographic parameters of a taekwondo elite athlete in order to prevent the risk of injury.
Materials and methods: The specific training protocol provided 2 months of general strength conditioning, which included
pre-conditioning in the first 2 weeks, physical training to improve explosive strength, balance and postural control and athletic
training to improve the combat technique. The experimental design included three assessment times: the pre-test (T0), the intermediate-
test (T1) and the post-test (T2). Each test provided the same evaluations: anthropometric measurements, cervical ROM
assessment and posturographic evaluation.
Results: Stabilometric parameters showed a good balance and postural control both in T0 and T2. Baropodometric parameters
showed a physiological load pressure distribution between the left and the right foot in T0 (left foot 54% - right foot 46%) as
well as in T2 (left foot 45% - right foot 55%). The left forefoot-rearfoot ratio pressure showed no differences between T0 and T2
(p>0.05); we found an improvement on the right forefoot-rearfoot ratio (p<0.05). Cervical range of motion evaluation showed no
significant variations from T0 to T2 (p>0.05) on rotation and lateral bending movements; we found an improvement on the extension
movement from T0 to T2 (p<0.05), while the flexion movement decreased (p>0.05).
Conclusion: The presented case study showed that the experimental protocol improved the postural parameters of this taekwondo
elite athlete. We believe that other athletes may adopt this protocol in order to improve own sports performance and to prevent
injuries
Effects of pilates exercise programs in people with chronic low back pain: a systematic review
The Pilates method has recently become a fast-growing popular way of exercise recommended for healthy individuals and those engaged in rehabilitation. Several published studies have examined the effects of Pilates method in people with chronic low back pain (LBP).The objective of this study is to describe and provide an extensive overview of the scientific literature comparing the effectiveness of the Pilates method on pain and disability in patients with chronic nonspecific LBP. The study is based on the data from the following sources: MEDLINE-NLM, MEDLINE-EBSCO, Scopus Elsevier, Cochrane, DOAJ, SciELO, and PLOSONE.Original articles and systematic reviews of adults with chronic nonspecific LBP that evaluated pain and/or disability were included in this study; studies in which the primary treatment was based on Pilates method exercises compared with no treatment, minimal intervention, other types of intervention, or other types of exercises.The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) were adopted. The literature search included 7 electronic databases and the reference list of relevant systematic reviews and original articles to July 2014. Two independent investigators conducted the literature search and performed the synthesis as follows: Study Design; Sample (n); Disability measure; Intervention; and Main results.The searches identified a total of 128 articles. From these, 29 were considered eligible and were included in the analysis. The items were stratified as follows: Pilates method versus other kind of exercises (n = 6 trials) and Pilates method versus no treatment group or minimal intervention for short-term pain (n = 9 trials); the therapeutic effect of the Pilates method in randomized cohorts (n = 5); and analysis of reviews (n = 9).We found that there is a dearth of studies that clearly demonstrates the efficacy of a specific Pilates exercise program over another in the treatment of chronic pain. However, the consensus in the field suggests that Pilates method is more effective than minimal physical exercise intervention in reducing pain. These conclusions need to be supported by other proper investigations
Influence of occlusal vertical dimension on cervical spine mobility in sports subjects
Introduction: In the scientific literature, a number of studies have reported conflicting results regarding the effects of occlusal vertical dimension (OVD) on sports-related skills. The purpose of this study was to increase OVD in sports subjects so as to specifically investigate the influence on cervical spine mobility. In particular, we measured cervical range of motion (ROM) before and after increasing OVD in individuals, either with or without malocclusion, analyzing both sports and sedentary subjects. Materials and methods: Participants were divided into two groups: a sports group (SG) and a control group (CG), each including 18 subjects. The SG was composed of sports subjects (age: 20.11±3.45 yrs; BMI: 25.39±2.32 kg/m2), whereas the CG consisted of age-matched sedentary subjects (age: 25.78±2.26 yrs; BMI: 24.88±2.87 kg/m2). Cervical range of motion (ROM) was evaluated, by way of an accelerometer (MooverŸ, Sensor MedicaŸ), before (pre-test) and after (post-test) increasing OVD. Results: The main finding of this study was that sports subjects showed no significant difference, compared to control subjects, in cervical ROM in response to increased OVD. Moreover, we found that sports and sedentary subjects alike showed no significant change in cervical spine mobility as a result of increased OVD, regardless of whether they were affected by malocclusion (class II) or represented subjects with normocclusion (class I). Conclusion: In accord with several studies reported in the literature, the findings of our study indicate that occlusal splints failed to significantly improve the physical-performance endpoint measured, i.e. cervical ROM, in sports subjects as compared to sedentary individuals. Due to the paucity of studies, characterized by conflicting results, there is as yet no compelling scientific evidence as to whether OVD positively impacts sports performance or not. Accordingly, we suggest that further scientific investigation, regarding the relationship between sports performance and OVD, be conducted in the field of sport and exercise sciences
Does Adiponectin Act as an Antiangiogenic Factor in B-Cell Chronic Lymphocytic Leukemia?
Angiogenesis is involved in the pathogenesis of B-cell chronic lymphocytic leukemia (CLL), and high microvascular density has been found in CLL to be associated with a poor prognosis. In this study, we assessed serum levels of adiponectin in 69 patients with Binet stage A B-CLL, and these values were retrospectively correlated with bone marrow (BM) microvessel area and serum levels of vascular endothelial growth factor (VEGF), fibroblast growth factor-2 (FGF-2), angiogenin, PECAM-1 (CD31), matrix metalloproteinase-9 (MMP-9), interleukin-8 (IL-8), syndecan-1, and the percentage of CD38+ or ZAP-70+ CLL cells. The positive correlation between serum levels of adiponectin and VEGF (P = .03) does not translate into an increase of the extent of BM angiogenesis (P = .404), FGF-2 (P = .348), angiogenin (P = .402), and CD31 (P = .248) serum concentrations. Accordingly, IL-8 (P = .175), syndecan-1 (P = .06), and MMP-9 (P = .144) circulating levels were not likely to reflect adiponectin concentration. Furthermore, patients with higher levels of adiponectin had a more favorable biological profile as defined by a lower number of both CD38â (r = â0.294; P = .02) and ZAP-70+ (r = â0.285; P = .04). Finally, we evaluated the presence of adiponectin in B-CLL cells at gene expression level. RMA intensity values for adiponectin gene transcript denote a homogeneous low expression in B-CLL cells, whereas VEGF transcript was highly expressed with a degree of interpatient variability. Overall, these data seem to indicate that adiponectin could be involved as an antiangiogenic factor in B-CLL
One repetition maximum bench press performance: a new approach for its evaluation in inexperienced males and females. A pilot study
The aim of this study was to evaluate a new method to perform the one repetition maximum (1RM) bench press test, by combining previously validated predictive and practical procedures. Eight young male and 7 female participants, with no previous experience of resistance training, performed a first set of repetitions to fatigue (RTF) with a workload corresponding to â
of their body mass (BM) for a maximum of 25 repetitions. Following a 5-min recovery period, a second set of RTF was performed with a workload corresponding to Âœ of participantsâ BM. The number of repetitions performed in this set was then used to predict the workload to be used for the 1RM bench press test using Mayhewâs equation. Oxygen consumption, heart rate and blood lactate were monitored before, during and after each 1RM attempt. A significant effect of gender was found on the maximum number of repetitions achieved during the RTF set performed with Âœ of participantsâ BM (males: 25.0 ± 6.3; females: 11.0x± 10.6; t = 6.2; p < 0.001). The 1RM attempt performed with the workload predicted by Mayhewâs equation resulted in females performing 1.2 ± 0.7 repetitions, while males performed 4.8 ± 1.9 repetitions. All participants reached their 1RM performance within 3 attempts, thus resulting in a maximum of 5 sets required to successfully perform the 1RM bench press test. We conclude that, by combining previously validated predictive equations with practical procedures (i.e. using a fraction of participantsâ BM to determine the workload for an RTF set), the new method we tested appeared safe, accurate (particularly in females) and time-effective in the practical evaluation of 1RM performance in inexperienced individuals
Match Load Physical Demands in U-19 Professional Soccer Players Assessed by a Wearable Inertial Sensor
Background: Wearable inertial sensors are poorly used in soccer to monitor external load (EL) indicators. However, these devices could be useful for improving sports performance and potentially reducing the risk of injury. The aim of this study was to investigate the EL indicators (i.e., cinematic, mechanical, and metabolic) differences between playing positions (i.e., central backs, external strikers, fullbacks, midfielders, and wide midfielder) during the first half time of four official matches (OMs). Methods: 13 young professional soccer players (Under-19; age: 18.5 ± 0.4 years; height: 177 ± 6 cm; weight: 67 ± 4.8 kg) were monitored through a wearable inertial sensor (TalentPlayers TPDev, firmware version 1.3) during the season 2021-2022. Participants' EL indicators were recorded during the first half time of four OMs. Results: significant differences were detected in all the EL indicators between playing positions except for two of them (i.e., distance traveled in the various metabolic power zones (<10 w) and the number of direction changes to the right >30° and with speed >2 m). Pairwise comparisons showed differences in EL indicators between playing positions. Conclusions: Young professional soccer players showed different loads and performances during OMs in relation to playing positions. Coaches should consider the different physical demands related to playing positions in order to design the most appropriate training program
Effects of a ludic-motor program on motor development and early literacy skills in preschool children
There is insufficient evidence in the literature about many correlations between motor and cognitive skills in 3-5 year old children [1]. The aim of this study was to explore the relationship between the development of the gross motor skills and the prerequisites of reading/writing following a ludic-motor program (LMP) in pre-school children. This study has involved 189 children (age: 4.62 ± 0.97 years; height: 107.83 ± 7.82 cm, body weight: 19.84 ± 4.95 kg) attending 8 kindergartens in Palermo. The children were randomly divided in a control group (C, n= 29), a 1-intervention group (I-1, n= 120) and a 2-intervention group (I-2, n= 40). I-1 and I-2 respectively performed 4 and 10 hours/week of a 16-week LMP carried out by outside experts; while C children do not perform any LMP. This program was planned in 21 learning modules aimed to develop bodily schemes, basic motor skills, fine motor control and coordination abilities. Before and after the LMP, locomotor and object control skills were evaluated with the Test of Gross Motor Development, while early reading/writing skills with the PRCR-2 test. Analyses of covariance were performed to compare outcomes for I1, I2 and C groups at post-test and the covariate was the participantsâ measure of cognitive skills at pre-test. Statistical significance was defined at
Challenges in UV camera-based real-time SO2 flux monitoring: insights from 5 years of continuous observations at Etna ad Stromboli
The advent of UV cameras has recently paved the way to volcanic SO2 flux observations of much improved temporal and spatial resolution, and has thus contributed to expanding use and utility of SO2 fluxes in volcano monitoring. Recently, the first examples of permanent UV camera systems have appeared that are now opening the way to routine fully automated monitoring of the volcanic SO2 flux at high-rate, and continuously (daily hours only). In 2014, using funding from the FP7-ERC project âBridgeâ (http://www.bridge.unipa.it/), we deployed a network of 4 permanent UV cameras at Etna and Stromboli volcanoes (Sicily) that has been operating regularly since then. Using a suite of custom-built codes, data streamed by the UV camera are automatically processed and telemetered, allowing nearly real-time visualization and analysis of SO2 fluxes. Here, we summarise the key results obtained during the last 5 years of continuous observations (2014-2018) to demonstrate potentials and challenges in real-time continuous SO2 flux monitoring with UV cameras. We show that the spatially resolved SO2 flux time-series delivered by the UV camera allow effectively tracking migration in volcanic activity from the Central to New South-East Crater (Etna), and shifts in degassing activity along the crater terrace (Stromboli). At both volcanoes, the high temporal of UV cameras allows capturing the escalation in active (strombolian) SO2 degassing that typically precedes onset of paroxysmal (Etna in 2014-2016) or effusive (Stromboli in 2014) activity, and to quantify for the first time the syn- explosive SO2 budget for larger-scale explosions, including 2 paroxysmal lava fountains (Etna) and 1 major explosion (Stromboli). We finally demonstrate the ability of our automatic camera systems to capture temporal changes in SO2 flux regime, and thus to âliveâ monitoring degassing and eruptive behaviors at active volcanoes.PublishedNapoli6V.
