Effective Stretching Positions of the Piriformis Muscle Evaluated Using Shear Wave Elastography.

CONTEXT: Piriformis syndrome is often associated with muscle spasms and shortening of the piriformis muscle (PM). Physical therapy, including static stretching of the PM, is one of the treatments for this syndrome. However, the effective stretching position of the PM is unclear in vivo. This study aimed to determine the effective stretching positions of the PM using ultrasonic shear wave elastography. DESIGN: Observational study. METHODS: Twenty-one healthy young men (22.7 [2.4] y) participated in this study. The shear elastic modulus of the PM was measured at 12 stretching positions using shear wave elastography. Three of the 12 positions were tested with maximum internal rotation at 0°, 20°, or 40° hip adduction in 90° hip flexion. Nine of the 12 positions were tested with maximum external rotation at positions combined with 3 hip-flexion angles (70°, 90°, and 110°) and 3 hip-adduction angles (0°, 20°, and 40°). RESULTS: The shear elastic modulus of the PM was significantly higher in the order of 40°, 20°, and 0° of adduction and higher in external rotation than in internal rotation. The shear elastic modulus of the PM was significantly greater in combined 110° hip flexion and 40° adduction with maximum external rotation than in all other positions. CONCLUSION: This study revealed that the position in which the PM was most stretched was maximum external rotation with 110° hip flexion and 40° hip adduction.

Effects of percussion massage therapy, dynamic stretching, and static stretching on physical performance and balance.

BACKGROUND: Percussion massage therapy is a popular approach in sport medicine for physical therapists, but few researchers have investigated the comparison with other intervention methods. OBJECTIVE: This study aimed to examine the comparison of the effects of dynamic stretching, static stretching and percussive massage therapy on balance and physical performance in individuals. METHODS: The participants who were 18-25 years of age, able to perform performance tests, did not have any orthopedic surgery, did not have problems during running and sudden turning, and did not have a professional sports history were included in the study. Participants were assigned randomly to three groups as dynamic stretching (DS) (n= 16), static stretching (SS) (n= 16) and percussive massage therapy (PMT) (n= 16) groups. Horizontal jumping test, T drill test and balance measurements on a single leg with open and closed eyes of all participants were recorded before and after applications. RESULTS: When the values of the pre and post-treatment of all groups in the study were compared, significant improvements were observed in the t-test, horizontal jumping test and right/left foot balance with eyes open in DS group (p< 0.05). Significant improvements were observed in all values in the PMT group (p< 0.05). In the comparison of the differences between the groups, PMT group values were more significant than the SS group in all parameters. CONCLUSION: Percussive massage therapy would be an alternative that can be used to increase the performance and balance of individuals before exercise.

Global posture reeducation compared with segmental muscle stretching exercises in the treatment of fibromyalgia: a randomized controlled trial.

BACKGROUND: Muscle stretching exercises preserve corporal flexibility and decrease the retraction and shortening of myofascial and articular structures. These exercises are recommended for the treatment of fibromyalgia (FM). The purpose of the study was to verify and compare the effect of muscle stretching exercises on FM patients based on the global posture reeducation method against segmental muscle stretching exercises, both used in concert with an educational approach rooted in cognitive behavioral therapy. METHODS: Forty adults with FM were randomly allocated into two groups: global and segmental. The two kinds of therapies were performed in 10 individual sessions once a week. Two assessments were made: one at baseline and one at the end of therapy. The primary outcome variable was pain intensity (Visual Analog Scale). The secondary outcome variables were multidimensional pain (McGill Pain Questionnaire), the pain threshold at tender points (dolorimetry), attitudes toward chronic pain (Survey of Pain Attitudes-Brief Version), body posture (Postural Assessment Software Protocol), postural control (Modified Clinical Test of Sensory Interaction on Balance), flexibility (sit-and-reach test), the impact of FM on quality of life (Fibromyalgia Impact Questionnaire, FIQ), and self-reported perceptions and body self-care. RESULTS: At the end of treatment, there were no statistically significant differences between the groups in the outcome variables. Furthermore, the groups presented lower pain intensity (baseline vs. final; global group: 6 ± 1.8 vs. 2.2 ± 1.6 cm, p<0.01; segmental group: 6.3 ± 2.1 vs. 2.5 ± 1.7 cm, p<0.01), higher pain threshold (p ≤ 0.01), lower total FIQ score (p < 0.01), and greater postural control (p < 0.01) after treatment. CONCLUSIONS: Muscle stretching exercises based on global posture reeducation and segmental muscle stretching exercises, both used in concert with an educational approach rooted in cognitive behavioral therapy, reduced the pain intensity and impact of FM on quality of life. These exercises also improved FM patients' pain threshold at tender points, attitudes toward chronic pain, and postural control. There were no differences between global posture reeducation and segmental muscle stretching exercises. TRIAL REGISTRATION: ClinicalTrials.gov NCT02384603 . Registered on 10 March 2015.

Effects of whole-body cryotherapy and static stretching are maintained 4 weeks after treatment in most patients with chronic fatigue syndrome.

In the previous study, whole-body cryotherapy (WBC)+static stretching (SS) has been shown to reduce the severity of some symptoms in Chronic Fatigue Syndrome (CFS) noted just after the therapy. Here we consider the effects of treatment and explore the sustainability of symptom improvements at four weeks (one-month) follow-up. Twenty-two CFS patients were assessed one month after WBC + SS programme. Parameters related to fatigue (Chalder Fatigue Questionnaire (CFQ), Fatigue Impact Scale (FIS), Fatigue Severity Scale (FSS)), cognitive function (Trial Making test part A and B (TMT A and TMT B and its difference (TMT B-A)), Coding) hemodynamic, aortic stiffness (aortic systolic blood pressure (sBP aortic)) and autonomic nervous system functioning were measured. TMT A, TMT B, TMT B-A and Coding improved at one month after the WBC + SS programme. WBC + SS had a significant effect on the increase in sympathetic nervous system activity in rest. WBC + SS had a significant, positive chronotropic effect on the cardiac muscle. Peripheral and aortic systolic blood pressure decreased one month after WBC + SS in comparison to before. Effects of WBC + SS on reduction of fatigue, indicators of aortic stiffness and symptoms severity related to autonomic nervous system disturbance and improvement in cognitive function were maintained at one month. However, improvement in all three fatigue scales (CFQ, FIS and FSS) was noted in 17 of 22 patients. In addition, ten patients were treated initially but they were not assessed at 4 weeks, and are thus not included in the 22 patients who were examined on follow-up. The overall effects of WBC + SS noted at one month post-treatment should be interpreted with caution.

Efficacy of proprioceptive neuromuscular facilitation in improving shoulder biomechanical parameters, functionality, and pain after axillary lymph node dissection for breast cancer: A randomized controlled study.

PURPOSE: Axillary lymph node dissection and radiotherapy have been associated with pain, physical symptoms, and decreased functional abilities in the upper extremity. This study aimed to evaluate the potential effects of the proprioceptive neuromuscular facilitation (PNF) technique on muscle strength, pain and functionality in this patient group in comparison with progressive resistance training (PRT). METHODS: The study was conducted with a randomized clinical trial design. Sixty-six women were included in the study and randomly divided into three groups: the PNF group (n = 22), the PRT group (n = 22), and the control group (n = 22). The participants were evaluated at the baseline and after eight weeks of treatment. Outcome measures were determined as pain (the Visual Analog Scale), upper extremity strength (isokinetic dynamometer), functionality (the Disabilities of the Arm, Shoulder and Hand questionnaire), and perception of change (the Global Rating of Change Scale). TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT05288036. RESULTS: The results showed statistically significant changes in both treatment groups in terms of shoulder flexors/extensors, abductor/adductors, internal/external rotators strength/power/endurance measurement, pain, and functionality (p < 0.05). Concerning functionality and perception of change, the PNF group had a statistically significantly higher improvement compared to the remaining two groups (p < 0.05). CONCLUSION: PNF is an effective technique in increasing upper extremity muscle strength, reducing pain during rest and activity, and improving functionality in patients receiving breast cancer treatment.

Using Long-Duration Static Stretch Training to Counteract Strength and Flexibility Deficits in Moderately Trained Participants.

Many sports injuries result in surgery and prolonged periods of immobilization, which may lead to significant atrophy accompanied by loss of maximal strength and range of motion and, therefore, a weak-leg/strong-leg ratio (as an imbalance index ∆ ) lower than 1. Consequently, there are common rehabilitation programs that aim to enhance maximal strength, muscle thickness and flexibility; however, the literature demonstrates existing strength imbalances after weeks of rehabilitation. Since no study has previously been conducted to investigate the effects of long-duration static stretch training to treat muscular imbalances, the present research aims to determine the possibility of counteracting imbalances in maximal strength and range of motion. Thirty-nine athletic participants with significant calf muscle imbalances in maximal strength and range of motion were divided into an intervention group (one-hour daily plantar flexors static stretching of the weaker leg for six weeks) and a control group to evaluate the effects on maximal strength and range of motion with extended and bent knee joint. Results show significant increases in maximal strength (d = 0.84-1.61, p < 0.001-0.005) and range of motion (d = 0.92-1.49, p < 0.001-0.002) following six weeks of static stretching. Group * time effects (p < 0.001-0.004, η² = 0.22-0.55) revealed ∆ changes in the intervention group from 0.87 to 1.03 for maximal strength and from 0.92 to 1.11 in range of motion. The results provide evidence for the use of six weeks of daily, one hour stretching to counteract muscular imbalances. Related research in clinical settings after surgery is suggested.

Influence of One Hour versus Two Hours of Daily Static Stretching for Six Weeks Using a Calf-Muscle-Stretching Orthosis on Maximal Strength.

Rebuilding strength capacity is of crucial importance in rehabilitation since significant atrophy due to immobilization after injury and/or surgery can be assumed. To increase maximal strength (MSt), strength training is commonly used. The literature regarding animal studies show that long-lasting static stretching (LStr) interventions can also produce significant improvements in MSt with a dose-response relationship, with stretching times ranging from 30 min to 24 h per day; however, there is limited evidence in human studies. Consequently, the aim of this study is to investigate the dose-response relationship of long-lasting static stretching on MSt. A total of 70 active participants (f = 30, m = 39; age: 27.4 ± 4.4 years; height: 175.8 ± 2.1 cm; and weight: 79.5 ± 5.9 kg) were divided into three groups: IG1 and IG2 both performed unilateral stretching continuously for one (IG1) or two hours (IG2), respectively, per day for six weeks, while the CG served as the non-intervened control. MSt was determined in the plantar flexors in the intervened as well as in the non-intervened control leg to investigate the contralateral force transfer. Two-way ANOVA showed significant interaction effects for MSt in the intervened leg (ƞ2 = 0.325, p < 0.001) and in the contralateral control leg (ƞ2 = 0.123, p = 0.009), dependent upon stretching time. From this, it can be hypothesized that stretching duration had an influence on MSt increases, but both durations were sufficient to induce significant enhancements in MSt. Thus, possible applications in rehabilitation can be assumed, e.g., if no strength training can be performed, atrophy could instead be reduced by performing long-lasting static stretch training.

Mechanisms Underlying Anti-Inflammatory and Anti-Cancer Properties of Stretching-A Review.

Stretching is one of the popular elements in physiotherapy and rehabilitation. When correctly guided, it can help minimize or slow down the disabling effects of chronic health conditions. Most likely, the benefits are associated with reducing inflammation; recent studies demonstrate that this effect from stretching is not just systemic but also local. In this review, we present the current body of knowledge on the anti-inflammatory properties of stretching at a molecular level. A total of 22 papers, focusing on anti-inflammatory and anti-cancer properties of stretching, have been selected and reviewed. We show the regulation of oxidative stress, the expression of pro- and anti-inflammatory genes and mediators, and remodeling of the extracellular matrix, expressed by changes in collagen and matrix metalloproteinases levels, in tissues subjected to stretching. We point out that a better understanding of the anti-inflammatory properties of stretching may result in increasing its importance in treatment and recovery from diseases such as osteoarthritis, systemic sclerosis, and cancer.

Combination of whole body cryotherapy with static stretching exercises reduces fatigue and improves functioning of the autonomic nervous system in Chronic Fatigue Syndrome.

BACKGROUND: The aim of this study was to explore the tolerability and effect of static stretching (SS) and whole body cryotherapy (WBC) upon fatigue, daytime sleepiness, cognitive functioning and objective and subjective autonomic nervous system functioning in those with Chronic Fatigue Syndrome (CFS) compared to a control population. METHODS: Thirty-two CFS and eighteen healthy controls (HC) participated in 2 weeks of a SS + WBC programme. This programme was composed of five sessions per week, 10 sessions in total. RESULTS: A significant decrease in fatigue was noted in the CFS group in response to SS + WBC. Some domains of cognitive functioning (speed of processing visual information and set-shifting) also improved in response to SS + WBC in both CFS and HC groups. Our study has confirmed that WBC is well tolerated by those with CFS and leads to symptomatic improvements associated with changes in cardiovascular and autonomic function. CONCLUSIONS: Given the preliminary data showing the beneficial effect of cryotherapy, its relative ease of application, good tolerability, and proven safety, therapy with cold exposure appears to be an approach worth attention. Further studies of cryotherapy as a potential treatment in CFS is important in the light of the lack of effective therapeutic options for these common and often disabling symptoms.

As was not observed in the CG, Oncofitness provided a reduction in some of the symptoms related to oncological treatments by improving joint range of motion.

Poor Trunk Flexibility is Associated with Cardiovascular Risk Factors

Abstract Background: Poor flexibility is a predictor of reduced physical activity. The association between trunk flexibility and cardiovascular risk factors (CVRFs) is not well understood. Objective: To identify the prevalence of CVRFs and their association with trunk flexibility in individuals participating in a community-based health education program. Methods: Volunteers (51 men, 48 women) aged 20-85 years old, participants in a community-based health education program in the city of Santo Antônio de Goiás, Brazil, were selected for this study. Anthropometric measures including body mass, height, body mass index (BMI), waist circumference (WC) and waist/height ratio (WHtR) were evaluated. Physical activity level was evaluated based on leisure activity participation, and trunk flexibility was evaluated by the sit and reach test. Data distribution was assessed using the Shapiro-Wilk test; Pearson's chi-square or Fisher's exact and Student t tests were performed for comparisons. To analyze the association between trunk flexibility and concomitant CVRFs, Spearman's correlation test and linear regression were employed. Statistical significance was defined as p < 0.05. Results: 7.2% of the volunteers had no CVRF, 10.3% had only one CVRF and 82.5% had two or more CVRFs, with no differences between sexes. Increased abdominal adiposity, as assessed by WHtR (p = 0.0097), and systemic arterial hypertension (p = 0.0003) were the most prevalent CVRFs, with differences between age groups. A strong negative correlation was found between mean trunk flexibility and the number of concomitant CVRFs (r = -0.96, p < 0.0028). Conclusion: The strong negative correlation between trunk flexibility and concomitant CVRF indicates an increased risk for cardiovascular events. Therefore, trunk flexibility measurement may be an additional tool for health promotion and prevention of cardiovascular and associated diseases in community health programs.

Introdução: os cuidados com os trabalhadores é uma importante questão de saúde pública. Objetivo: avaliar os efeitos da ginástica laboral (GL) na flexibilidade da coluna cervical e lombar de servidores do hospital universitário. Materiais e Métodos: trata-se de um estudo experimental. Participaram do estudo, 50 colaboradores distribuídos em dois grupos: Controle (CTL, n=25) e Experimental (EXP, n=25). O grupo CLT não participou das aulas de GL e o grupo EXP realizou 16 sessões de GL, quatro vezes por semana, por quatro semanas. A flexibilidade da coluna cervical e lombar dos participantes foi realizada em dois momentos, antes de iniciarem o programa de GL e após 16 sessões. Resultados: foi verificado que a prática de GL resultou em um aumento da flexibilidade cervical. Em relação à coluna lombar, o período de intervenção não impediu a redução da flexibilidade, no entanto, essa redução foi 50% menor no grupo EXP quando comparado ao grupo CTL. Conclusão: o programa de GL é uma estratégia de intervenção fundamental para a saúde do trabalhador, visto que a flexibilidade é um importante componente da atividade física relacionada à saúde.

Introduction: care of workers is an important public health issue. Objective: to evaluate the effects of occupational gymnastics (OG) on the flexibility of the cervical and lumbar spine of employees at the university hospital. Materials and Methods: this is an experimental study. A total of 50 employees participated in the study, divided into two groups: Control (CTL, n = 25) and Experimental (EXP, n = 25). The CLT group did not participate in the OG classes and the EXP group had 16 OG sessions, which took place four times a week, for four weeks. The flexibility of the cervical and lumbar spine of the participants was assessed in two moments, before starting the OG program and after 16 sessions. Results: it was observed that the practice of OG resulted in an increase in cervical flexibility. Regarding the lumbar spine, the intervention period did not prevent the reduction in flexibility; however, this reduction was 50% lower in the EXP group when compared to the CTL group. Conclusion: the OG program is a fundamental intervention strategy for workers' health, since flexibility is an important component of physical activity related to health.

Effective stretching position for the posterior deltoid muscle evaluated by shear wave elastography.

BACKGROUND: Deteriorated extensibility of the posterior deltoid muscle is one of the factors of posterior shoulder tightness, and improvement in its extensibility is needed. However, no study has investigated which shoulder positions effectively stretch the posterior deltoid muscle in vivo. The aim of this study was to verify the effective stretching position of the posterior deltoid muscle in vivo by shear wave elastography. METHODS: Fifteen healthy men participated in this study. The shear modulus of the posterior deltoid was measured at resting and 13 stretching positions: 60°, 90°, and 120° shoulder flexion; maximum shoulder flexion, horizontal adductions at 60°, 90°, and 120° shoulder flexion; internal rotations at 60°, 90°, and 120° shoulder flexion; and combinations of horizontal adduction with internal rotation at 60°, 90°, and 120° shoulder flexion. The shear moduli of each stretching position were compared to those of the rest. Then, among the stretching positions for which the shear modulus was significantly different from the rest, the shear moduli were compared using a three-way analysis of variance with repeated measures of the 3 factors-flexion, horizontal adduction, and internal rotation. RESULTS: The shear moduli in all stretching positions were significantly higher than those of the rest, except for maximum shoulder flexion. The three-way analysis of variance with repeated measures revealed significant main effects in flexion and horizontal adduction. Comparing the flexion angles, the shear modulus was significantly higher at 90° than that at 60° and 120°. The shear modulus with horizontal adduction was significantly higher than that without horizontal adduction. Moreover, a significant two-way interaction was found only at flexion and horizontal adduction. The shear modulus with horizontal adduction was significantly higher at all angles than that without horizontal adduction at each flexion angle. Comparing the flexion angles with horizontal adduction, the shear modulus was significantly higher at 90° than that at 60° and 120°. No significant three-way interactions were found. CONCLUSION: Shoulder flexion and horizontal adduction affected the extensibility of the posterior deltoid muscle, whereas the effect of shoulder internal rotation was limited. More precisely, maximal horizontal adduction at 90° shoulder flexion was the most effective stretching position for the posterior deltoid muscle.

Physiotherapy Management of Migraine Pain: Facial Proprioceptive Neuromuscular Facilitation Technique Versus Connective Tissue Massage.

OBJECTIVE: Physical therapy modalities are often used by patients with migraine pain. The effectiveness of the methods in the treatment of migraine has not been clarified yet. This prospective study was planned to investigate whether facial proprioceptive neuromuscular facilitation is superior to connective tissue massage in the treatment of migraine pain. METHODS: The study was conducted on 40 female patients with a neurologist-confirmed diagnosis of chronic migraine with non-aura, and who were aged between 18 and 65. They were randomly divided into 2 groups. Facial proprioceptive neuromuscular facilitation techniques were applied to the patients in the study group (Group 1), and connective tissue massage was applied to the patients in the control group (Group 2). The interventions were performed 3 times a week for approximately 20 minutes. Pain and pressure pain threshold scores were recorded on the first day of treatment before starting the session and were reassessed immediately after the end of the 18 treatment (6 weeks) sessions. RESULTS: Pretreatment and posttreatment results were similar in both groups in terms of pain scores and pressure pain threshold values ( P > 0.05). Both groups improved in pain-related outcomes ( P < 0.05). CONCLUSIONS: Our results suggest that facial proprioceptive neuromuscular facilitation was no more effective than connective tissue massage for treating migraine for the sample size used in the present study. Both methods can be used in the treatment of migraine pain.

Flexibility and achilles tendon: a brief review / Flexibilidade e tendão de aquiles: uma breve revisão

Performing flexibility training in an exercise program is important to improve range of motion (ROM). Tendons have a profound impact on the general function of the musculoskeletal system, influence the limitation of ROM, and its structure and mechanical properties can benefit from stretching protocols. The systematic use of lower limbs in locomotion caused the Achilles tendon to become the largest and strongest tendon in the human body. Therefore, understanding the best prescription and frequency of flexibility exercise leads to changes in tendon properties is essential for an appropriate and effective exercise routine. Thus, the aim of this review was to organize and discuss publications about the implications of triceps surae stretching in ROM, as well as its influence on tendon properties. Acute studies show that continuous stretching times between five and 10 minutes cause decreased tendon stiffness, which is not seen in fractionated stretching times less than five minutes. Chronic studies, in turn, also don't present significant results in stiffness with fractionated times and studies with continuous times were not found. Thus, it is not possible to know if a continuous stretching time (longer than one minute) or a total time longer than five minutes but fractionated, can influence the tendon stiffness. (AU)

A realização de treino de flexibilidade como rotina em um programa de exercícios é importante para melhorar amplitude de movimento (ADM). Os tendões têm um impacto profundo na função geral do sistema musculoesquelético, influenciam na limitação da ADM, e sua estrutura e propriedades mecânicas podem se beneficiar de protocolos de alongamento. O uso sistemático dos membros inferiores na locomoção fez com que o tendão de Aquiles se tornasse o maior e mais forte tendão do corpo humano. Portanto, entender qual a melhor prescrição e frequência de exercício de flexibilidade para que ocasione alterações nas propriedades tendíneas é essencial para uma rotina de exercícios adequada e eficaz. Sendo assim, o objetivo dessa revisão de literatura foi organizar e discutir publicações sobre as implicações do alongamento do tríceps sural na ADM, bem como sua influência nas propriedades tendíneas. Estudos agudos mostram que tempos contínuos entre cinco e 10 minutos de alongamento estático causam diminuição da rigidez tendínea, o que não é visto em tempos intervalados inferiores a cinco minutos. Os estudos crônicos, por sua vez, também não apresentam resultados significativos na rigidez com protocolos de alongamento intervalados e estudos com protocolos contínuos não foram encontrados. Dessa forma, não é possível saber se um tempo contínuo de alongamento (superior a um minuto) ou um tempo superior a cinco minutos, intervalado, podem influenciar na rigidez tendínea. (AU)

Effect of concurrent training (aerobic+resistance) more static stretching on flexibility in women with breast cancer / Efeito do treinamento concorrente (aeróbio + resistência) mais alongamento estático na flexibilidade em mulheres com câncer de mama

Objective. was to assess flexibility in women with breast cancer who underwent concurrent training (aerobic+resistance) (CT) more static stretching. Methods. This was a controlled pilot study, with 31 women (age 30 to 59) under breast cancer treatment, 14 women were allocated to a training group (TG) who underwent CT more static stretching, concomitant to hospital treatment and 17 women for the control group (CG) who only underwent hospital treatment. The CT more static stretching was performed in 12 weeks with 5 sessions per week, three sessions (aerobic+resistance) and two sessions (stretching exercises) on alternate days. The flexibility of the shoulder was measured by means of the 360º Sanny pendulum goniometer and the flexibility of the lower limbs was assessed through the sit-and-reach test. Data were analyzed using repeated measures ANOVA Test and Bonferroni Post-hoc using SPSS 21 software, with α of 5%. Results. The TG presented increased flexibility in the horizontal abduction of the right shoulder (p=0.001) and in the lower limbs (p<0.001), but the CG showed a reduction in the horizontal abduction of the right shoulder (p=0.003). The effect size for horizontal abduction of the right shoulder was medium (p=0.508) and for the lower limbs was large (p=0.839). Conclusion. CT more static stretching may be a therapeutic intervention to increase flexibility of upper and lower limbs in women with breast cancer. (AU)

Objetivo. Avaliar a flexibilidade em mulheres com câncer de mama que realizaram treinamento concorrente (aeróbio + resistência) (TC) mais alongamento estático. Métodos. Este foi um estudo piloto controlado, com 31 mulheres (de 30 a 59 anos) em tratamento para câncer de mama, 14 mulheres foram alocadas em um grupo de treinamento (GT) que realizaram TC mais alongamento estático, concomitante a tratamento hospitalar e 17 mulheres para o grupo de controle (GC) que somente realizaram tratamento hospitalar.

O tamanho do efeito para abdução horizontal do ombro direito foi médio (p=0,508) e para membros inferiores foi grande (p=0,839). Conclusão. O TC mais alongamento estático podem ser uma intervenção terapêutica para aumentar a flexibilidade de membros superiores e inferiores em mulheres com câncer de mama. (AU)

Os efeitos do stretching global ativo em bailarinas clássicas / The effects of global active stretching on classical ballet dancers

INTRODUÇÃO: O Stretching Global Ativo (SGA) pode ser uma boa estratégia para a melhora da postura e qualidade de vida e para a redução da dor. Ele atua com alongamentos de cadeias musculares podendo proporcionar melhora da prática do balé sem grandes estresses físicos. OBJETIVO: Verificar os efeitos do SGA na postura, dor e qualidade de vida de bailarinas clássicas. MATERIAIS E MÉTODOS: Foi um ensaio clínico randomizado no período de novembro de 2020 a outubro de 2021. Constituiu-se de 20 bailarinas (idade entre 12 e 22 anos), sem lesões ortopédicas ou em recuperação, e sem tratamento fisioterapêutico. Estas foram divididas em dois grupos. O grupo controle em que não houve nenhuma intervenção e o grupo SGA, o qual realizou três posturas durante 15 minutos para cada, duas vezes por semana, totalizando 10 sessões. Avaliouse por meio do Questionário de Qualidade de Vida do Atleta, Questionário Nórdico Musculoesquelético e pelo Software para Avaliação Postural, empregando os testes t (independência), teste t (pareado), teste G (contingência) e o Qui-quadrado. RESULTADOS: Não houve diferença estatística na qualidade de vida e dor, porém no grupo controle houve aumento da extensão do corpo (0,003) e dorsiflexão do tornozelo (0,01); e no grupo SGA, houve aumento do valgo de joelho esquerdo (0,05), redução da rotação interna da cabeça do fêmur (0,01) e extensão do joelho esquerdo. CONCLUSÃO: Houve efeitos do SGA apenas na postura das bailarinas, fato não encontrado na dor e qualidade de vida das mesmas.

INTRODUCTION: Global Active Stretching (GAS) can be a good strategy for improving posture and quality of life, as well as reducing pain. It works by stretching muscle chains and can improve ballet practice without major physical stress. OBJECTIVE: To verify the effects of GAS on posture, pain and quality of life of classical ballet dancers. MATERIALS AND METHODS: It was a randomized clinical trial from November 2020 to October 2021, consisting of 20 dancers (aged between 12 and 22 years), without orthopedic or recovering lesions, and without physical therapy treatment. They were divided into two groups. The control group, in which there was no intervention and the SGA group, which performed three postures twice a week for 15 minutes each, for total of 10 sessions. The Athlete's Quality of Life Questionnaire, The Nordic Musculoskeletal Questionnaire, and the Postural Assessment Software were evaluated using the t tests (independence), the t test (paired), the G test (contingency) and the Chi-square. RESULTS: There was no statistical difference in quality of life and pain, but in the control group there was an increase in body extension (0.003) and ankle dorsiflexion (0.01); and in the SGA group, there was an increase in left knee valgus (0.05), reduction of internal rotation of the femoral head (0.01) and left knee extension. CONCLUSION: There SGA affected only on posture of the dancers, but not their pain and quality of life. Brazilian Registry of Clinical Trials (ReBEC) protocol RBR-10wckkk7.

PNF- based Gait Rehabilitation-training after a Total Hip Arthroplasty in congenital pelvic malformation; A case report.

INTRODUCTION: Congenital dysplasia of the pelvis often occurs in isolation, however, it can also involve other pelvic components, and anomalies of the digestive system. Pelvic malformations have effects on the pelvic girdle and pelvic stability influencing the quality of gait. The condition can be treated with a total hip arthroplasty (THA). The concept of Proprioceptive Neuromuscular Facilitation (PNF) has been described as a comprehensive rehabilitation approach with a focus on motor learning. This case report seeks to illustrate the clinical reasoning and feasibility of applying the PNF-concept in a patient after a THA with multiple congenital pelvis malformations. CASE DESCRIPTION: A male, 44 years of age, physically active laborer was treated with THA after hip dysplasia, with comorbid missing pubic symphysis. The patient presented with complaints in gait speed, gait distance, hip joint mobility and stability. PATIENT MANAGEMENT: PNF-based motor-control training, including specified PNF-pattern exercises with specific PNF-facilitation principles and techniques was provided over a period of eighteen weeks. Results showed improvements beyond the minimal detectable change and/or the minimal clinically important difference for physical functioning in gait, strength, range of motion, and personal required activities. DISCUSSION AND CONCLUSION: Gait rehabilitation training, restoring altered movement patterns in the patient's activities of daily living was provided with PNF. Besides targeting structural impairments, this approach elicited motor learning effects. PNF-patterns have been described as: "mimicking functional activities" from daily life and sports. A specified PNF-based therapy including motor learning components, was a feasible approach in this case of complex pelvic skeletal malformations.

Radial nerve palsy following humeral shaft fracture: a theoretical PNF rehabilitation approach for tendon and nerve transfers.

BACKGROUND: Humerus fracture-induced radial nerve injury can create severe and permanent disabilities. PURPOSE: Surgical management often relies on either tendon or nerve transfer. Regardless of which procedure is selected, physical therapists are challenged to restore functional outcomes without jeopardizing repair healing. Through synergistic, multi planar upper extremity movement patterns, neuromuscular irradiation, or overflow, and neuroplasticity, proprioceptive neuromuscular facilitation (PNF) may improve strength, range of motion and tone. METHODS: After reviewing the literature, a five phase PNF-based treatment approach is proposed with timing differences based on the selected procedure. FINDINGS: Phase I (2 or 4 weeks pre-surgery for tendon or nerve transfer, respectively) consists of comprehensive patient education; Phase II (4-6 or 1-2 weeks post-surgery for tendon or nerve transfer, respectively) explores variable duration peripheral and central nervous system motor learning during isometric activation to enhance central neuroplasticity; Phase III (7-12 or 3-20 weeks post-surgery for tendon or nerve transfer, respectively) incorporates low-intensity motor control including contralateral isotonic upper extremity loading to maximize overflow and neuroplastic effects; Phase IV (13-26 or 21-52 weeks post-surgery for tendon or nerve transfer, respectively) adds high-intensity strength and motor control using ipsilateral isotonic upper extremity loading to maximize overflow and neuroplastic effects. Phase V (27-52 or 53-78 weeks post-surgery for tendon or nerve transfer, respectively) progresses to more activity of daily living, vocational, or sport-specific training with higher intensity strength and motor control tasks. CONCLUSIONS: Through manually guided synergistic, multi planar movement, overflow, and neuroplasticity, a PNF treatment approach may optimize neuromuscular recovery. Validation strategies to confirm clinical treatment efficacy are discussed.
