The influence of balance support base manipulation on the kinematics of lower limbs during single-legged squats in people with patellofemoral pain.

Background: Given that people with patellofemoral pain (PFP) exhibit deficits in postural control, certain postural reactions may be associated with movement alterations in this population. Therefore, the objective of the present study was to investigate whether manipulation of the support base for balance maintenance could lead to different patterns of lower limb kinematics in people with PFP during single-legged squats.

Methods: Fourteen participants with PFP and 14 asymptomatic controls were first assessed performing single-legged squats freely, and then while holding a stick to provide stabilization during the task.

Objective: To perform a cross-cultural translation of the Student Evidence-Based Practice Questionnaire (S-EBPQ) and Evidence-Based Practice Evaluation Competence Questionnaire (EBP-COQ) into Brazilian Portuguese; to adapt and validate the Brazilian Portuguese versions for use with healthcare students from diverse courses; and to assess the measurement properties of the translated and adapted versions.

Methods: Four hundred forty-two healthcare students were included, and three versions were tested: S-EBPQ-BR, EBP-COQ-BR for nursing students, and EBP-COQ-BR for healthcare students.

Effect of foam rolling recovery on pain and physical capacity after resistance exercises: A randomized crossover trial.

Objectives: To compare the effects of passive recovery (PR), active recovery (AR), and recovery through self-massage with the aid of foam rolling (FRR) on pain and physical capacity in healthy volunteers after a resistance exercise (RE) session.

Methods: The sample of this randomized crossover trial comprised 37 physically healthy men who underwent three sessions of RE (squat, leg press, and leg extension), involving four sets of 10 repetitions with 80% of 10MR, with an interval of seven days between sessions. PR consisted of sitting for 20min, AR included a cycle ergometer for 20min at 50% maximum heart rate, and FRR involved 10 repetitions per target body area, followed by 1min rest.

Vitamin E Does not Favor Recovery After Exercises: Systematic Review and Meta-analysis.

Injuries and complaints in the Brazilian national volleyball male team: a case study.

Background: The literature reports a vast amount of epidemiological information on injuries in volleyball athletes. However, little is known about the incidence of injuries in elite athletes of international level participating in major competitions, such as world championships and Olympic games. The objective of the study was to analyse the incidence of injuries in elite professional volleyball athletes, and the prevalence of complaints reported by athletes.

Intra and interrater reliability for lower limb flexibility assessment using photogrammetry.

Introduction: Photogrammetry represents an advancement in the flexibility evaluation, and although it was highly explored for postural assessment, there is a scarcity of studies analyzing lower limb angular measurements using it. The purpose of this study is to verify the reliability of intrarater and interrarater photogrammetry in assessing lower limb flexibility.

Methods: This was a randomized cross-sectional observational study with test-retest design and a two-day interval.

Relationship between kinesiophobia, isometric hip and knee torques to pelvic, hip and knee motion during the single-leg drop jump in women with patellofemoral pain: A cross-sectional study.

Background: Individuals with patellofemoral pain (PFP) have kinesiophobia and hip and knee strength deficits. These factors may be related to kinematic alterations of pelvic, hip and knee during a more demanding functional activity, such as jumping landing. The aim was to investigate the relationships between kinesiophobia and hip/knee torque to pelvic/hip/knee kinematics during the single-leg drop vertical jump in women with PFP.

We searched the MEDLINE, Embase, CINAHL, SPORTDiscus, Cochrane Library, and Web of Science, from inception up to January 2023.

Where do Physiotherapists Search for Information? Barriers in Translating Scientific Information into Clinical Practice.

Introduction: Comprehending scientific information have been reported as a barrier in evidence-based practice (EBP) adoption. This survey research aimed to verify the preferred sources of information for acquiring knowledge about physiotherapy and the association between types of information source and barriers in EBP implementation.

Methods: A total of 610 physiotherapists were included and answered an online questionnaire about the preferred sources for searching physiotherapy-related information and possible barriers in EBP implementation.

Keep posting and following social media profiles about physical therapy, but be aware! A cross-sectional study of social media posts on Instagram and Twitter.

Background: Social media is established as a communication channel that is useful to disseminate scientific information. While social media can disseminate high quality information, it can also facilitate the spread of false or misleading information. Furthermore, social media is considered a self-promotion environment that can have several aspects related to personal marketing.

Is Postural Control Affected in People with Patellofemoral Pain and Should it be Part of Rehabilitation? A Systematic Review with Meta-analysis.

Background: Growing evidence supports that exercise therapy is effective for patellofemoral pain (PFP) rehabilitation. Nevertheless, the improvements have been reported not to be sustained in the long term, suggesting that the current protocols may not comprehend all required functional factors to provide a consistent recovery. A potential neglected factor in treatment protocols for PFP is postural control.

Background: The execution of undergraduate thesis is a period in which students have an opportunity to develop their scientific knowledge. However, many barriers could prevent the learning process. This cross-sectional study aimed to analyze the scientific dissemination of results from undergraduate theses in physical therapy programs and verify the existence of barriers and challenges in the preparation of undergraduate thesis.

Adding muscle power exercises to a strength training program for people with patellofemoral pain: protocol of a randomized controlled trial.

Background: Strong evidence supports the proximal combined with quadriceps strengthening for patellofemoral pain (PFP) rehabilitation. However, most reported rehabilitation programs do not follow specific exercise prescription recommendations or do not provide adequate details for replication in clinical practice. Furthermore, people with PFP have power deficits in hip and knee muscles and it remains unknown whether the addition of power exercises would result in superior or more consistent outcomes.

Gluteal muscle activity during running in asymptomatic people.

Background: Hip abductor muscle function is associated with running-related injuries. Previous electromyography (EMG) studies that reporting gluteal muscle activity when running have failed to account for the multiple segments of the gluteals, and have used surface electrodes, which may be contaminated by cross-talk of surrounding muscles.

Research Question: This study aimed to: (i) develop EMG profiles of gluteus medius (GMed - anterior, middle and posterior) and gluteus minimus (GMin - anterior and posterior) segments during running; (ii) compare the activation patterns of each gluteal segment between running and walking; and (iii) compare surface EMG signals of running and walking to fine wire EMG signals of middle GMed.

Relationship between the architecture and function of ankle plantar flexors with Achilles tendon morphology in ballet dancers.

Achilles tendinopathy is the most frequent foot overuse injury in ballet dancers and knowledge of clinically modifiable factors related to tendon structure in a population at risk, such as ballet dancers, would be important for the development of preventive programs. Therefore, the present study aimed to assess relationships of gastrocnemius muscle architecture and ankle plantar flexors function with Achilles tendon morphology in ballet dancers. Fifty-four measures from 27 ballet dancers were collected.

Acute Effects of Hip Mobilization With Movement Technique on Pain and Biomechanics in Females With Patellofemoral Pain: A Randomized, Placebo-Controlled Trial.
