Republished research: Effects of circuit training as alternative to usual physiotherapy after stroke: randomised controlled trial
This article is an abridged version of a paper that was published on bmj.com. Cite this article as: BMJ 2012;344:e2672 Abstract Study question What is the effect of task oriented circuit training compared with usual physiotherapy in terms of self reported walking competency for patients with stroke discharged from a rehabilitation centre to their own home? Summary answer Task oriented circuit training started in the first six months is as effective as individually tailored physiotherapy for patients with moderate to mild stroke and allows patients to exercise more intensively with a lower ratio of staff to patients. What i...

Whole-Body Vibration Intensities in Chronic Stroke: A Randomized Controlled Trial
Conclusion: The addition of the 30-session WBV paradigm to the leg exercise protocol was no more effective in enhancing body functions/structures, activity, and participation than leg exercises alone in chronic stroke patients with mild to moderate motor impairments.

Performance in 200 m front crawl: coordination index, propulsive time and stroke parameters
Abstract The aim of this study was to compare coordination index, propulsive time, duration of stroke phases and kinematic parameters over 200 m front crawl. Variables were compared among four sections of 50 m (T1 to T4) in fifteen competitive swimmers (age: 21.1 ± 7.1 years; height: 180.1 ± 6.1 cm; height: 187.3 ± 8, 1 cm; body mass: 72.1 ± 10.1 kg; better performance in the race: 77.5 ± 4.7% of the world record). Data were obtained with two video cameras (60 Hz - coupled to a cart on rails on the side of the pool) for simultaneous images of the swimme r ’ s sagittal plan: below the water line and above the water l...

Improvements in fitness at 12-months follow up of an individualised home and community based exercise program after stroke
Introduction: Low cardiorespiratory fitness levels and sedentary patterns of behaviour are common even in well-recovered stroke survivors. These characteristics increase their risk of secondary stroke or other cardiovascular disease events. There are few longitudinal exercise intervention studies in stroke, especially studies targeting cardiorespiratory fitness. The aim of this study was to evaluate the longer-term effects of an individually tailored, home and community based exercise program in stroke survivors on cardiorespiratory fitness, ambulation and quality of life.

Effect of Whole-Body Vibration on Neuromuscular Activation of Leg Muscles During Dynamic Exercises in Individuals With Stroke
This study examined the leg muscle activity during exposure to different whole-body vibration (WBV) intensities while performing various dynamic exercises in patients with chronic stroke. Thirty patients with chronic stroke performed a series of dynamic exercises under 3 conditions: (a) low-intensity WBV (peak acceleration: 0.96 units of gravity of Earth [g]), (b) high-intensity WBV (1.61 g), and (c) no WBV. Neuromuscular activation was recorded with surface electromyography (EMG) on bilateral biceps femoris (BF), vastus lateralis, tibialis anterior (TA), and gastrocnemius (GS) in both legs and was reported as EMGrms (root...

Forces during front crawl swimming at different stroke rates
In this study, a coupled biomechanical-smoothed particle hydrodynamics (SPH) method is used to determine when peak arm thrust occurs and how the ratio of arm –leg thrust changes with stroke rate. A dynamic biomechanical model of a female national-level swimmer was generated from a three-dimensional laser body scan of the athlete and multi-angle videos of sub-maximal swimming trials. This was coupled to the SPH method to simulate the fluid moving around the body during front crawl swimming. Two distinct peaks in net streamwise thrust were found during the stroke coinciding with the underwater arm strokes. The peak arm thr...

Hyperbaric oxygen-associated seizure leading to stroke.
We report an event in which a seizure and stroke occurred together and consider that the stroke may have been caused by seizure-induced demand ischaemia. This challenges the generally held view that oxygen toxicity seizures in the clinical hyperbaric setting are benign. A discussion of the literature on the subject of seizure-induced brain injury is included. Risk factors for cerebrovascular disease should be taken into consideration in determining treatment pressures for HBOT, as reducing pressure reduces seizure risk.

Does a Perturbation Based Gait Intervention Enhance Gait Stability in Fall Prone Stroke Survivors? A Pilot Study.
Authors: Punt M, Bruijn SM, van de Port IG, de Rooij IJM, Wittink H, van Dieën JH Abstract A recent review indicated that perturbation based training (PBT) interventions are effective in reducing falls in older adults and patients with Parkinson's disease. It is unknown whether this type of intervention is effective in stroke survivors. We determined whether PBT can enhance gait stability in stroke survivors. Ten chronic stroke survivors who experienced falls in the past six months participated in the PBT. Participants performed 10 training sessions over a six-week period. The gait training protocol was progressiv...

The effects of predictive trials on critical stroke rate and critical swimming speed.
CONCLUSIONS: This study demonstrated that CSR and CSS were not statistically different when determined with different predictive trials located within the recommended durations of 2-12 min. Nevertheless, CSR200-800 and CSS200-800 exhibited the best consistency with CSR200-400-800 and CSS200-400-800, respectively. PMID: 32614153 [PubMed - as supplied by publisher]

Roundtable on Preseason Heat Safety in Secondary School Athletics: Prehospital Care of Patients With Exertional Heat Stroke.
CONCLUSIONS: Exertional heat stroke continues to be a leading cause of sudden death in young athletes and the physically active. This may be partly due to the numerous barriers and misconceptions about the best practice for diagnosing and treating patients with EHS. Exertional heat stroke is survivable if it is recognized early and appropriate measures are taken before patients are transported to hospitals for advanced medical care. Specifically, best practice for EHS evaluation and treatment includes early recognition of athletes with potential EHS, a rectal temperature measurement to confirm EHS, and cold-water immersion...

Propulsive Force of Upper Limbs and its Relationship to Swim Velocity in the Butterfly Stroke
Int J Sports Med DOI: 10.1055/a-1386-4985The aims of this study were to: (1) verify the sex effect; (2) assess upper limb asymmetry in anthropometrics and propulsive force variables; and (3) identify the main determinants of butterfly swim velocity based on a set of anthropometrics, kinematics, and propulsive force variables. Twenty swimmers (10 males: 15.40±0.30 years; 10 females: 14.43±0.23 years) at the national level were recruited for analysis. A set of anthropometrics, kinematics, and propulsive force variables were measured. Overall, a significant sex effect was verified (...

Acute Effects of Frequent Light-Intensity Standing-Based Exercises That Interrupt 8  Hours of Prolonged Sitting on Postprandial Glucose in Stroke Survivors: A Dose-Escalation Trial
CONCLUSION: Interrupting 8 hours of prolonged sitting at least every 90 minutes with light-intensity standing-based exercises attenuates postprandial glucose in stroke survivors. During the morning, postprandial glucose is attenuated when sitting is interrupted every 60 and 90 minutes.PMID:33952707 | DOI:10.1123/jpah.2020-0516
