Quantifying training variables of a physical exercise modality is essential for an appropriate dosage. In training with elastic bands, time under tension (TUT) and force represent the duration and intensity of this force-training modality. The aims of this study were to evaluate the degree of compliance to TUT prescription for three different scenarios of two exercises and the comparison of the force values obtained versus the estimate values. A total of 29 healthy volunteers were evaluated in a clinical environment under controlled conditions in 3 different scenarios (different velocities or ROMs) of both shoulder abduction and knee extension in 2 sets of 10 repetitions per scenario within a single session. Concentric and isometric phases showed a higher degree of compliance for their TUTs than the eccentric phase TUTs for all scenarios of both exercises, whereas the degree of compliance was higher for the total TUT than for the phases’ TUTs. Additionally, the eccentric phase showed a general tendency to develop for longer time periods than prescribed, whilst the fast scenario showed a higher degree of compliance for isometric phase TUTs and total TUTs than the extant two scenarios in both exercises. On the other hand, the force of the elastic bands tends to be overestimated according to the estimates of the manufacturers. These findings, both those related to the degree of compliance with TUTs and the force analysis, can be used by physiotherapists and other exercise professionals as a reference to achieve a good dosage of routine exercises with elastic bands.

AbstractSeveral types of routines and methods have been experimented to gain neuro/muscular advantages, in terms of overall range of motion, in athletes and fitness enthusiasts. The aim of the present study was to evaluate the impact of different routines on trunk- and lower limbs flexibility in a sample of young women. In a randomized-crossover fashion, eleven subjects underwent to: hamstrings stretching [S]; hamstrings stretching plus whole-body vibration [S+WBV]; partial-body cryotherapy [Cryo]; rest [Control]. Standing hamstrings stretch performance and sit-and-reach amplitude resulted to be improved with [S+WBV] compared to all other protocols (p<0.05). [Cryo] ameliorated the active knee extension performance with respect to all other interventions (p<0.05). These flexibility improvements were obtained without a loss in the trunk position sense proprioception. These results represent the first evidence that a single session of either vibration or cryotherapy can ameliorate flexibility without losing the trunk position sense proprioception in young women.

The purpose of this investigation was to compare isometric test procedures (make vs. break tests by muscle groups) with elementary school girls, ages 9–11, using hand-held dynamometry. Fifty subjects in Grades 3 and 4 performed three trials on four muscle groups using each testing procedure following a preliminary session to allow familiarity with the instrumentation, test procedures, and test positions. Retest measurements were taken in 5–7 days with the order of the test procedures counterbalanced. Four 2 × 2 (Side × Test Condition) AM0VAs, with repeated measures on each-factor, were used to analyze the data. Significant Side × Test Condition interaction effects were evident for knee extension, elbow flexion, and shoulder abduction. Except for the knee extension, the break test produced higher values than the make test in all muscle groups, which is in agreement with previous investigations.

Abstract Background and Purpose. Most patients with hip fracture do not return to prefracture functional status 1 year after surgery. The literature describing interventions, however, does not use classic overload and specificity principles. The purpose of this case report is to describe the use of resistance training to improve functional outcomes in a patient following hip fracture. Case Description. The patient was a 68-year-old woman who had a comminuted intertrochanteric fracture of the left hip 3 months previously. She used a cane for ambulation, and her walking was limited. The patient received 16 sessions of lower-extremity strengthening exercises, aerobic training on a stationary bicycle, functional training supervised by a physical therapist, and a home stretching program. Outcome. The patient's isometric muscle force for involved hip extension, hip abduction, and knee extension improved by 86%, 138%, and 33%, respectively; walking endurance increased by 22.5%; balance improved by 400%; balance confidence increased by 41%; and self-reported ability to perform lower-extremity functional activities increased by 20%. Discussion. The authors believe that some patients can perform comprehensive exercise programs after hip fracture and that properly designed programs can affect patient outcomes beyond observed impairments.

The Impact

Introduction: The surgical procedure for myocardial revascularization (MRI) may compromise chest stability, compliance and range of motion (ROM) of the shoulder joint due to sternotomy and knee joint due to saphenectomy. Objective: To evaluate the impact of myocardial revascularization surgery on upper and lower limb ROM Methodology: This is a prospective cohort study, performed with a group of patients submitted to cardiac surgery. In the preoperative period the ROM was evaluated through a goniometer, for flexion, horizontal abduction and vertical abduction of the right and left shoulder, as well as evaluation of the flexo-extension movement of the right knee. On the day of discharge from the Intensive Care Unit, the patients were reassessed. Results:Twenty patients were evaluated during the time of the study. The majority were men 14 (70%), with a mean age of 60 ± 10 years. Regarding ROM, it was verified that all the movements presented a significant reduction in the postoperative period. The right shoulder flexion (75 ± 11ºvs66 ± 8º, p = 0, p <0.01), right shoulder abduction (155 ± 17º vs127 ± 22º, p < (P = 0.02), right vertical abduction (142 ± 24º vs117 ± 22º, p <0.01), left vertical abduction (142 ± 24º vs121 ± 22º, p = 0), left horizontal abduction (79 ± 9º vs70 ± 5º, p=0,02), Knee flexion (100 ± 14º vs75 ± 19º, p <0.01) and knee extension (94 ± 13º vs79 ± 15º, p <0.01). Conclusion: It can be concluded that the surgery promote reduction of the range of joint motion in this sample of patients submitted to myocardial revascularization.

Background: Osgood-Schlatter disease (OSD) affects 1 in 10 adolescents. There is a lack of evidence-based interventions, and passive approaches (eg, rest and avoidance of painful activities) are often prescribed. Purpose: To investigate an intervention consisting of education on activity modification and knee-strengthening exercises designed for adolescents with OSD. Study Design: Case series; Level of evidence, 4. Methods: This study included 51 adolescents (51% female; age range, 10-14 years) with OSD. The 12-week intervention consisted of an activity ladder designed to manage patellar tendon loading and pain, knee-strengthening exercises, and a gradual return to sport. The primary outcome was the global reporting of change at 12 weeks, evaluated with a 7-point Likert scale (successful outcome was considered “much improved” or “improved”). Additional endpoints were at 4, 8, 26, and 52 weeks. Secondary outcomes included the Knee injury and Osteoarthritis Outcome Score (KOOS), objective strength, and jump performance. Results: Adolescents reported a mean pain duration of 21 months at enrollment. After 12 weeks, 80% reported a successful outcome, which increased to 90% at 12 months. At 12 weeks, 16% returned to playing sport, which increased to 69% at 12 months. The KOOS subscores of Pain, Activities of Daily Living, Sport and Recreation, and Quality of Life improved significantly (7-20 points), and there were improvements in knee extension strength (32%; P < .001), hip abduction strength (24%; P < .001), and jumping for distance (14%; P < .001) and height (19%; P < .001) at 12 weeks. Conclusion: An intervention consisting of activity modification, pain monitoring, progressive strengthening, and a return-to-sport paradigm was associated with improved self-reported outcomes, hip and knee muscle strength, and jumping performance. This approach may offer an alternative to passive approaches such as rest or wait-and-see, often prescribed for adolescents with OSD. Registration: NCT02799394 ( ClinicalTrials.gov identifier)

Background and purposeDespite numerous optimization attempts, time delays are still a relevant problem in endovascular stroke treatment. We hypothesized that public display of the fastest procedural times in our institution would raise awareness, which would result in improved procedural times.MethodsWe established a competition, which lasted 6 months, in which the fastest neurovascular team in terms of procedural times (image to reperfusion) was displayed on a public board in our institution and rewarded with public praise. During this time no other relevant procedural or infrastructural means for improvement of procedural times were introduced in our institution. We prospectively evaluated procedural times in 496 patients who received endovascular stroke treatment 9 months before the competition, during the competition, and during the four 6-month time periods for 2 years after the competition.ResultsMedian image-to-reperfusion times improved significantly from 98 min before the competition to 85 min during the competition (p=0.005) and remained stable with a median of 81 min 2 years after the competition (p=0.837).ConclusionWe were able to improve our procedural times significantly with a simple and cost-efficient competition. This effect was sustained 2 years after the competition was completed, implying that the improvement in procedural times was probably due to raised awareness.

Context: Limited passive hamstring flexibility might affect kinematics, performance, and injury risk during running. Pre-activity static straight-leg raise stretching often is used to gain passive hamstring flexibility. Objective: To investigate the acute effects of a single session of passive hamstring stretching on pelvic, hip, and knee kinematics during the swing phase of running. Design: Randomized controlled clinical trial. Setting: Biomechanics research laboratory. Patients or Other Participants: Thirty-four male (age = 21.2 ± 1.4 years) and female (age = 21.3±2.0 years) recreational athletes. Intervention(s): Participants performed treadmill running pretests and posttests at 70% of their age-predicted maximum heart rate. Pelvis, hip, and knee joint angles during the swing phase of 5 consecutive gait cycles were collected using a motion analysis system. Right and left hamstrings of the intervention group participants were passively stretched 3 times for 30 seconds in random order immediately after the pretest. Control group participants performed no stretching or movement between running sessions. Main Outcome Measure(s): Six 2-way analyses of variance to determine joint angle differences between groups at maximum hip flexion and maximum knee extension with an α level of .008. Results: Flexibility increased between pretest and post-test in all participants (F1,30 = 80.61, P&lt;.001). Anterior pelvic tilt (F1,30 = 0.73, P=.40), hip flexion (F1,30 = 2.44, P=.13), and knee extension (F1,30 = 0.06, P=.80) at maximum hip flexion were similar between groups throughout testing. Anterior pelvic tilt (F1,30 = 0.69, P=.41), hip flexion (F1,30 = 0.23, P=.64), and knee extension (F1,30 = 3.38, P=.62) at maximum knee extension were similar between groups throughout testing. Men demonstrated greater anterior pelvic tilt than women at maximum knee extension (F1,30 = 13.62, P=.001). Conclusions: A single session of 3 straight-leg raise hamstring stretches did not change pelvis, hip, or knee running kinematics.
