Shifting effects in randomised controlled trials of complex interventions: a new kind of performance bias?

2012

Gold C, Erkkila J, Crawford MJ. Shifting effects in randomised controlled trials of complex interventions: a new kind of performance bias? Objective:  Randomised controlled trials (RCTs) aim to provide unbiased estimates of treatment effects. However, the process of implementing trial procedures may have an impact on the performance of complex interventions that rely strongly on the intuition and confidence of therapists. We aimed to examine whether shifting effects over the recruitment period can be observed that might indicate such impact. Method:  Three RCTs investigating music therapy vs. standard care were included. The intervention was performed by experienced therapists and based on …

AB0929 Balance in fibromyalgia is not related with lower limb strength

2017

Background Postural control, that depends on many sensory contributors and motor skills, is altered in people with fibromyalgia (FM) 1–3. Knowing those contributors that could be impaired in this population is important to design an appropriate balance therapy. Objectives Due to the fact that people with FM use to present a strength loss 7, our main goal was to explore the relation between postural control and lower limb strength in this population. Further, the sensory inputs contributors to the postural control were assessed. Methods A cross-sectional study was conducted in a sample of 40 FM patients. A force platform was used to assess postural control under five bipedal conditions: i) e…

LOW BACK PAIN IN YOUNG TEAM SPORT PLAYERS: A RETROSPECTIVE STUDY

2014

Background Low back pain (LBP) is a common complaint in general population affecting both genders and almost all age-groups. LBP is a common problem in sports as well, even in younger populations. LBP is prone to recur, thus there is a need for studies on the early phases of the problem in different sports. Objective To investigate the prevalence, nature, severity and risk factors of self-reported LBP in young team sport players. Design A retrospective cross-sectional study. Setting Finnish female and male basketball, floorball, ice hockey and volleyball teams. Participants This study is a part of an ongoing cohort study exploring risk factors for sports injuries. Players from 22 teams, a t…

Children’s physical activity and sedentary time compared using assessments of accelerometry counts and muscle activity level

2018

Background This research compared accelerometry (ACC)-derived and muscle electromyography (EMG)-based estimates of physical activity (PA) and sedentary time in typical PA tasks and during the daily lives of children. Methods Data was included from two exploratory studies. In Study I, 6–7-year-old children (n = 11, 64% girls) were assessed for eight PA tasks (walking, stair negotiation, climbing, crawling, swinging, balancing, trampoline jumping and a game of tag). In Study II, 7–9-year-old children (n = 14, 38% girls) were assessed for six PA tasks (walking, sitting, static squat, single leg hops, jump for height and standing long jump), and daily PA during one day with and one day without…

The effects of a calisthenics training intervention on posture, strength and body composition

2017

BACKGROUND: Calisthenics was a term used to define a generic set of body weight exercises. Such term is now used to define a world wide spread discipline based on body weight and gymnastics exercises.OBJECTIVE: The aim of this study was to administer a calisthenics training protocol and evaluate its effects on posture, strength and body composition in untrained individuals.METHODS: Twenty-eight male participants (24.2 +/- 4.2 years; 67.0 +/- 8.3 Kg; 173.3 +/- 5.2 cm) were divided into two groups, a Calisthenics based intervention group (SG) and a control group (CG). The SG exercised for 8 weeks. Each participant underwent a body composition analysis, a postural assessment, a handgrip test, …

The Effects of Stochastic Galvanic Vestibular Stimulation on Body Sway and Muscle Activity

2020

Objective: This study aimed to investigate whether galvanic vestibular stimulation with stochastic noise (nGVS) modulates the body sway and muscle activity of the lower limbs, depending on visual and somatosensory information from the foot using rubber-foam.Methods: Seventeen healthy young adults participated in the study. Each subject maintained an upright standing position on a force plate with/without rubber-foam, with their eyes open/closed, to measure the position of their foot center of pressure. Thirty minutes after baseline measurements under four possible conditions (eyes open/closed with/without rubber-foam) performed without nGVS (intensity: 1 mA, duration: 40 s), the stimulation…

The so-called one-and-a-half syndrome, type II: a new syndrome?

1999

Objective: The term one-and-a-half syndrome, type II, was recently coined and has been applied to two somewhat different eye movement disorders: the loss of voluntary horizontal eye movements except for adduction in one eye (one patient with two lesions, one in the cerebral hemisphere and the other in the cavernous sinus) and the loss of all voluntary horizontal eye movements with adduction nystagmus in the right eye on attempted gaze to the left and preserved abduction in both eyes with the doll’s head maneuver (one patient with infarction of the midbrain). The justification of the term ‘one-and-a-half syndrome, type II’ is questioned. Design: Retrospective analysis of 9000 consecutive ele…

Association between frontal plane knee control and lower extremity injuries : a prospective study on young team sport athletes

2017

Background/aimPoor frontal plane knee control can manifest as increased dynamic knee valgus during athletic tasks. The purpose of this study was to investigate the association between frontal plane knee control and the risk of acute lower extremity injuries. In addition, we wanted to study if the single-leg squat (SLS) test can be used as a screening tool to identify athletes with an increased injury risk.MethodsA total of 306 basketball and floorball players participated in the baseline SLS test and a 12-month injury registration follow-up. Acute lower extremity time-loss injuries were registered. Frontal plane knee projection angles (FPKPA) during the SLS were calculated using a two-dimen…

Resting sympatho-vagal balance is related to 10 km running performance in master endurance athletes

2018

Relationships between heart rate recovery after exercise (HRR, baseline heart rate variability measures (HRV), and time to perform a 10Km running trial (t10Km) were evaluated in "master" athletes of endurance to assess whether the measured indexes may be useful for monitoring the training status of the athletes. Ten “master” athletes of endurance, aged 40-60 years, were recruited. After baseline measures of HRV, the athletes performed a graded maximal test on treadmill and HRR was measured at 1 and 2 minutes from recovery. Subsequently they performed a 10Km running trial and t10Km was related to HRV and HRR indexes. The time to perform a 10Km running trial was significantly correlated with …
