Differences between Sexes and Speed Levels in Pelvic 3D Kinematic Patterns during Running Using an Inertial Measurement Unit (IMU).

This study aimed to assess the 3D kinematic pattern of the pelvis during running and establish differences between sexes using the IMU sensor for spatiotemporal outcomes, vertical acceleration symmetry index, and ranges of motion of the pelvis in the sagittal, coronal, and transverse planes of movement. The kinematic range in males was 5.92°-6.50°, according to tilt. The range of obliquity was between 7.84° and 9.27° and between 9.69° and 13.60°, according to pelvic rotation. In females, the results were 6.26°-7.36°, 7.81°-9.64°, and 13.2°-16.13°, respectively. Stride length increased proportionally to speed in males and females. The reliability of the inertial sensor according to tilt and gait symmetry showed good results, and the reliability levels were excellent for cadence parameters, stride length, stride time, obliquity, and pelvic rotation. The amplitude of pelvic tilt did not change at different speed levels between sexes. The range of pelvic obliquity increased in females at a medium speed level, and the pelvic rotation range increased during running, according to speed and sex. The inertial sensor has been proven to be a reliable tool for kinematic analysis during running.

Effects of resistance training on patients with End-Stage Renal Disease: an umbrella review with meta-analysis of the pooled findings.

OBJECTIVES: This umbrella review aimed to review the effects of resistance training on patients with end-stage renal disease and assess the methodological quality of the available literature. METHODS: An umbrella review and meta-meta-analysis was performed. A systematic search was conducted until May 2022. Article selection, quality assessment, and risk of bias assessment were performed by two independent reviewers. The meta-meta-analyses were performed with a random-effects model and the summary statistics were presented in the form of a forest plot with a weighted compilation of all standardized mean differences and corresponding 95% confidence interval. Twenty-four reviews were eventually included. The protocol was registered in the international registry PROSPERO (CRD42022321702). RESULTS: Resistance training showed positive effects on functional capacity (g = 0.614), aerobic capacity (g = 0.587), health-related quality of life (g = 0.429), and peak force (g = 0.621). Fifteen of the included studies (63%) presented low risk of bias, and the remaining studies (37%) showed unclear risk of bias. CONCLUSION: Resistance training in patients undergoing hemodialysis is an intervention that shows positive results regarding physical and functional outcomes. The quality level of the literature is inconclusive, but the included studies present low risk of bias.

A dataset of the measurement of lower limb muscle strength with handheld dynamometry in patients undergoing hemodialysis.

The dataset presented in this article belongs to a test-retest reliability study of the assessment of lower limb muscle strength through handheld dynamometry in patients with End-Stage Renal Disease undergoing hemodialysis. The intervention was carried out at the Hospital de Manises, in Manises (Spain). The strength of different muscle groups in the lower limbs of participants undergoing hemodialysis was assessed at different points. The same researcher was in charge of doing all of the assessments, and a standardized protocol was followed to conduct the assessment. Data was collected during the dialysis sessions at different points of time. This dataset contains raw data obtained from those assessments. The analysis consisted in assessing the test-retest reliability, through the Intraclass Correlation Coefficient (ICC), of the measurement of strength in the lower limbs through handheld dynamometry. Further analysis for this raw data could be to compare results obtained in this sample with results obtained in the assessment of similar samples, or to supply relevant scientific evidence to include the measurement of lower limb strength in patients undergoing hemodialysis in experimental studies conducted in this population, such as interventions that include resistance training for the lower limbs as the intervention.

A dataset of the effects of therapeutic exercise programs on physical function in patients undergoing hemodialysis.

The dataset presented in this article belongs to a randomized controlled trial, conducted between November 2015 and May 2016, where therapeutic exercise interventions were implemented in patients with End-Stage Renal Diseases undergoing hemodialysis. The intervention was carried out at the Hospital de Manises, in Manises (Spain). Participants performed a 16-week exercise program either during dialysis (intradialytic) or at home, combining resistance and aerobic training. Tests were assessed prior to the dialysis session, and include several dimensions of the patient's functional status, such as functional capacity, physical performance, balance, lower limb strength and endurance, and handgrip strength. Data was collected prior to and after the implementation of an intervention. The dataset contains the raw data obtained in this data collection. The analysis consisted in the improvement of these outcomes when a therapeutic exercise intervention is implemented. Further analysis could potentially include the stratification of the sample in several subgroups according to demographic characteristics of the participants, according to levels of compliance to the intervention and according to even more specific changes within the tests performed. For instance, the improvement of the overall assessment of the Short Performance Physical Battery Test might differ from the improvement of any of the components that build this "battery" of tests, such as gait speed, balance, or the Sit-to stand-to sit 5 tests.

Psychometric properties of the translated Spanish version of the Pain Self-Efficacy Questionnaire.

Introduction: Some patients with rotator cuff injuries do not report significant changes in pain-related outcomes. Pain self-efficacy, which is commonly assessed using the Pain Self-Efficacy Questionnaire, may contribute toward this outcome. However, a Spanish adaptation of this questionnaire is currently lacking. Therefore, this study's purpose was developing the Spanish version of this questionnaire, and assess its psychometric properties. Methods: The Spanish version of the Pain Self-Efficacy Questionnaire was translated and culturally adapted, and a sample of 107 patients with rotator cuff injuries completed the questionnaire to examine its convergent validity (analyzing its correlation with the Tampa Scale of Kinesiophobia), its test-retest reliability, for which a subset of 40 participants completed again the questionnaire, and its internal consistency. Results: Translation was conducted without any problems, and 107 participants completed the study. Mean scores for the Pain Self-Efficacy Questionnaire were 45.2 points (standard deviation, 11.4). The Pain Self-Efficacy Questionnaire showed a moderate negative correlation with the Tampa Scale of Kinesiophobia (Pearson's correlation index r = -0.48) supporting its convergent validity. High test-retest reliability (Intraclass Correlation Coefficient of 0.90) and excellent internal consistency (Cronbach's α value of 0.92) were also found. Discussion: The Spanish version of the Pain Self-Efficacy Questionnaire presents high validity, test-retest reliability, and internal consistency to assess pain self-efficacy in patients suffering rotator cuff injuries in Spanish-speaking settings.

Associations between Preoperative Patient Socioeconomic Status and Pain-Related Outcomes with Pain and Function in Patients Undergoing Rotator Cuff Repairs.

BACKGROUND: Patients undergoing rotator cuff repairs commonly experience postoperative pain and functional limitations. Various socioeconomic and pain-related factors have been recognized as influential in the prognosis of such patients. This study aims to investigate the associations between postoperative pain and functionality and preoperative pain-related outcomes and socioeconomic status in patients undergoing rotator cuff repairs. METHODS: This cross-sectional study examines the relationship between the outcomes of rotator cuff repairs and participants' socioeconomic status and pain-related measures. Socioeconomic status was assessed through indicators such as educational level, monthly household income, and occupation. Pain-related outcomes included measures of kinesiophobia and pain self-efficacy. RESULTS: A total of 105 patients (68 male, 37 female) were included in the analysis. The findings revealed no significant association between postoperative pain or functionality and the patients' socioeconomic status (p > 0.05). However, postoperative pain levels demonstrated a significant association with preoperative kinesiophobia (p < 0.05) and pain self-efficacy (p < 0.013). In contrast, functionality did not exhibit a significant association with these measures (p < 0.072 and 0.217, respectively). CONCLUSIONS: Preoperative pain-related outcomes play a role in postoperative pain levels among patients undergoing rotator cuff repairs. However, they do not appear to be related to functionality. Additionally, socioeconomic status does not significantly impact either pain or functionality.

Invasive and Non-Invasive Electrical Neuromodulation in Trigeminal Nerve Neuralgia: A Systematic Review and Meta-Analysis.

BACKGROUND: Trigeminal neuralgia is a chronic disease characterized by intense facial pain that is caused by trigeminal nerve affectation. It usually affects adults from 50 years of age, and is more frequent in women. Additionally, it presents serious psychological effects that often lead to depression, which is why it is considered highly disabling. The therapeutic approach is based on the modification of nerve activity through electrical, surgical or chemical stimulation in specific regions of the nervous system. OBJECTIVE: To perform a meta-analysis of the scientific literature related to invasive and non-invasive electrical neuromodulation of trigeminal neuralgia, in order to assess their effects over pain and adverse effects. METHODS: A literature search was conducted in 4 databases, followed by a manual search of articles on invasive or non-invasive electrical neuromodulation to control the pain of trigeminal neuralgia, including the last 15 years. RESULTS: Regarding non-invasive methods, clinical trials did not present enough results in order to perform a meta-analysis. Regarding invasive methods, clinical trials meta-analysis showed no statistical differences between different treatment methods. In all cases, improvements in patients' pain were reported, although results regarding adverse effects were variable. CONCLUSION: In the treatment of trigeminal neuralgia, the continuous radiofrequency provides better short and medium-term results, but pulsed radiofrequency shows less adverse effects after treatment, and has better results in the long-term.

Barefoot Running: Between Fashion and Real Way to Prevent Joint Osteo Lesions?

BACKGROUND AND OBJECTIVES: Running has gone from a vital necessity for the man to a playful sport. Different rheumatic and orthopedic pathologies have appeared, in front of which the shoe industry has reacted by creating reinforced shoes that are supposed to overcome the induced lesions. Several years later, the trend toward reinforcement has gone toward minimalism, which is the absence of reinforcement, that is, a more natural race. METHOD: We observed variations of kinetics and kinematics in young, unprofessional, healthy runners during a shoe race and a shoeless race, which is the form of maximum minimalism. We then correlated minimalism variations with the variables of the race and the joint angles. RESULTS: We observed significant difference (P < 0.01) in the cycle rate, the cycle length, the step rate, and the angle of attack between running with and without shoes. A small variation of the minimalism index is associated with an increase in knee angle (r 2> 0.5). Conversely, a large variation in the minimalism index is related to a decrease in the knee angle (r 2> 0.5). The minimalism index has no impact on the angulation of the ankle and hip (r 2< 0.3). CONCLUSION: Slow transition will bring gains in terms of decreasing the length of the stride, which limits the load on the shin. Greater flexibility can be achieved by decreasing the flexion angle of the knee, which decreases the demand for quadriceps muscles and the risk of knee injury with a greater risk of injury at the tibial level.
