Comparative effects of lymphatic drainage and soft tissue mobilization on pain threshold, shoulder mobility and quality of life in patients with axillary web syndrome after mastectomy.

PURPOSE: The purpose was to compare the effects of manual lymphatic drainage and soft tissue mobilization on pain threshold, shoulder mobility and quality of life in patients with axillary web syndrome. METHODS: This randomized clinical trial was conducted on 36 breast cancer patients with developed axillary web; participants were randomly divided into two groups. One group was treated with manual lymphatic drainage; the other group was treated with soft tissue mobilizations in addition to therapeutic exercises, i.e., stretching, strengthening and range of motion (ROM) exercises. The duration of treatment was four weeks (5 sessions/week), with therapeutic exercises as a common treatment protocol. Outcome measures were Breast-Cancer specific quality of life questionnaires, Disabilities of the Arm, Shoulder and Hand (DASH), Numeric Pain Rating Scale (NPRS), Patient Specific Functional Scale (PSFS), Dynamometer and Goniometer. All outcome measure readings were recorded at baseline and the end (4th week) of the treatment. RESULTS: The compliance of the variable distribution with normal distribution was verified using the Shaphiro-Wilk test. Parametric tests were applied, and both groups showed significant effects (p < 0.05) in pairwise comparison (paired t-test). The comparison group analysis (independent t-test) showed that there was no significant difference in pain, upper limb strength, range of motions and fatigue component of quality of life questionnaire parameters (p > 0.05). Two parameters (DASH, PSFS) and one component of the quality of life questionnaire (global health) showed a significant difference (p < 0.05). CONCLUSION: Manual lymphatic drainage showed more improvement in functional movements. It was concluded that both groups, manual lymphatic drainage and soft tissue mobilization groups were clinically equally effective. TRIAL REGISTRATION NUMBER: This trial is registered at ClinicalTrial.gov PRS under trial number NCT05463185 on date 18/07/2022.

Objective: Muscle stretching is applied with the purpose of increasing range of motion. Different techniques are used for this purpose, including proprioceptive neuromuscular facilitation (PNF) and dynamic stretching, but it is still unclear which one is more effective. The objective of this research was to estimate the efficacy of the hold-relax technique compared to dynamic stretching on hamstring flexibility in healthy young adults. Methodology: Randomized controlled trial with blinding, consisting of two intervention arms. The study included a total of 32 young adult volunteers aged 18 to 30 years, who were randomized into two intervention groups: PNF (n = 16) and dynamic stretching (n = 16). Knee joint flexibility was assessed using the popliteal angle measured with a goniometer. Results: The mean age, weight, height, and body mass index were found to be equivalent, indicating comparable groups. No significant differences were found between the stretching groups in the adjusted means, with a mean difference of -2.09 (95 % CI -7.05 to 2.87). Conclusions: Both dynamic stretching and PNF demonstrated an increase in knee range of motion, with both stretching techniques showing differences from the baseline. No significant differences were found between the stretching groups.

Não foram encontradas diferenças entre os grupos de alongamento.

Comparison of utilizing modified hold-relax, muscle energy technique, and instrument-assisted soft tissue mobilization on hamstring muscle length in healthy athletes: Randomized controlled trial.

INTRODUCTION: The hamstring muscle shortness is the primary risk factor for sports-related injuries. Numerous treatments are available for lengthening of hamstring muscle. The main purpose of this study was to compare the immediate effect of modified hold-relax, muscle energy technique (MET), and instrument assisted soft tissue mobilization-Graston techniques (IASTM-GT) on length of hamstring muscle in young healthy athletes. METHODS: 60 athletes comprising of 29 females and 31 males were recruited in the present study. Participants were allocated to 3 groups of IASTM-GT (N = 20, 13 male, 7 female), Modified Hold-relax (N = 20, 8 male, 12 female), and MET (N = 20, 7 male, 13 female). Active knee extension and passive straight leg raising (SLR), and toe touch test were performed before and immediately after the intervention by a blinded assessor. For the comparison of dependent variables across time, 3*2 repeated measure ANOVA was utilized. RESULTS: Interaction of group by time was significant for passive SLR (P < 0.001). Interaction of group by time was not significant for active knee extension (P = 0.17). The results showed that dependent variables increased significantly in all groups. The effect size (Cohen's d) in the groups of IASTM-GT, modified Hold-relax, and MET was 1.7, 3.17, and 3.12, respectively. CONCLUSION: Although the measures were improved in all groups, it seems that IASTM-GT can be used as a safe and efficient treatment, which can be a suitable candidate alongside modified hold-relax and MET for increasing the hamstrings muscle length in healthy athletes.

Termoterapia associada com treinamento de flexibilidade não aprimora a amplitude de movimento de joelhos em adultos saudáveis: revisão sistemática de ensaios clínicos randomizados com meta-análise / Thermotherapy associated with flexibility training does not increase the knee range of movement of healthy adults: systematic review and meta-analysis of randomized clinical trials

The stretching with thermotherapies associated have been related in the literature as a way to increase the range of motion (ROM), but still are not consensus about this efficacy and costeffectiveness. The muscle stretching is a useful technique in rehabilitation and in physical activities programs, either to gain or maintain the flexibility, as a recovery of musculoskeletal and joint injuries. Objective: To determine the effects of thermotherapies associated to flexibility training in ROM of knee extension in healthy adults. Method: The search strategy was conducted in main databases, as Cochrane Library, LILACS, PEDro, PUBMED/ Medline, Scopus and Web of Science. The searches were done in 2016, and renewed in 2023, in order to achieve new publications along this time. Were selected only randomized clinical trials that have executed a training of hamstrings stretching, associated or not with one or more thermotherapies in healthy young adults, as long as the outcome was knee extension ROM. Only papers in Portuguese or English were assessed. To evaluate risk of bias was used the Cochrane Collaboration's Risk of Bias Tool, and the methodological quality assessment was rated following the PEDro Scale. Results: Eight articles were included, totalizing 260 participants. The papers showed low methodological quality, and uncertain risk of bias. Only chronic effect of local warming and cryotherapy plus stretching showed a statistically significant difference versus control group. However, the thermotherapy action associated with stretching is still unclear, once the results suggest that even without the thermotherapy there are ROM increases. Conclusion: The stretching is effective in knee extension ROM improvement in healthy adults, with or without thermotherapy. New studies with higher methodological rigor and standardized protocols are needed

Os alongamentos com termoterapias associadas têm sido relatados na literatura como forma de aumentar a amplitude de movimento (ADM), mas ainda não há consenso sobre sua eficácia e custo-efetividade. O alongamento muscular é uma técnica útil na reabilitação e em programas de atividades físicas, tanto para ganho ou manutenção da flexibilidade, quanto para recuperação de lesões musculoesqueléticas e articulares. Objetivo: Determinar os efeitos das termoterapias associadas ao treinamento de flexibilidade na ADM de extensão do joelho em adultos saudáveis. Método: A estratégia de busca foi realizada nas principais bases de dados, como Cochrane Library, LILACS, PEDro, PUBMED/ MedLine, Scopus e Web of Science. As buscas foram realizadas em 2016, e renovadas em 2023, a fim de alcançar novas publicações ao longo deste tempo. Foram selecionados apenas ensaios clínicos randomizados que tenham executado um treinamento de alongamento de isquiotibiais, associado ou não a uma ou mais termoterapias, em adultos jovens saudáveis, desde que o desfecho fosse ADM de extensão de joelho. Apenas artigos em português ou inglês foram avaliados. Para avaliar o risco de viés foi usado o Risk of Bias Tool da Cochrane Collaboration, e a avaliação da qualidade metodológica foi classificada de acordo com a Escala PEDro. Resultados: Foram incluídos oito artigos, totalizando 260 participantes. Os artigos apresentaram baixa qualidade metodológica e risco incerto de viés. Apenas o efeito crônico de aquecimento local e crioterapia associados ao alongamento mostrou uma diferença estatisticamente significativa em relação ao grupo controle. No entanto, a ação da termoterapia associada ao alongamento ainda não está clara, uma vez que os resultados sugerem que mesmo sem a termoterapia há aumento da ADM. Conclusão: O alongamento é eficaz na melhora da ADM de extensão do joelho em adultos saudáveis, com ou sem termoterapia. Novos estudos com maior rigor metodológico e protocolos padronizados são necessários

Hold-relax PNF is more effective than unilateral lumbar mobilization on increasing hamstring flexibility: A randomized clinical trial.

BACKGROUND: Although lumbar mobilization (LM) and proprioceptive neuromuscular facilitation (PNF) are used to increase flexibility in clinical practice, remains unclear which technic is the most effective. This study aims to verify and compare the immediate effect of unilateral LM and hold-relax PNF on hamstring flexibility. METHOD: A randomized, blinded, crossover trial carried out in university research laboratory. Thirty healthy young adults were randomly allocated to three groups, each group receive unilateral, central posterior-anterior LM grade III to the L4 joint, hold-relax PNF and control intervention in a different order with 48 h of washout period. Hamstring flexibility was measured using photogrammetry before and immediately after intervention through range of motion (ROM) change in the Straight Leg Raise Test. T-tests were used to compare ROM within groups, and ANOVA repeated measure followed by Bonferroni post-hoc tests was used for between groups comparison. RESULTS: Two participants were lost to follow-up, leaving 28 for analysis (21.6 ± 2.2 years-old). LM increased 4.5° (95% CI 2.3-6.5°, p = 0.001, d = 0.29) on the straight leg raise test and PNF increased 10.0° (95% CI 7.7-12.2°, p = 0.001, d = 0.7). No statistically significant increase was observed on the control group (p = 0.151, d = 0.08). Further, the technique used significantly influenced ROM (p = 0.001, η²p = 0.37). On the between group analysis, PNF was better than LM (p = 0.005) and control (p = 0.001), whereas LM was no better than the control for hamstring flexibility (p = 0.68). CONCLUSIONS: Although hold-relax PNF and unilateral LM techniques increased ROM, hold-relax PNF was more effective on increasing hamstring flexibility.

The acute effects of different hamstring muscle stretching techniques on reducing muscle resistance to movement by ultrasound elastography.

OBJECTIVE: Many stretching methods are applied on the hamstring muscles for reducing muscle resistance on movement. The aim of our study to investigate the acute effects of static stretching and the Mulligan traction straight leg raise (TSLR) technique administered to the hamstring muscles on reducing its resistance to movement. METHODS: The study included 22 healthy male volunteers (19.5 ± 0.98 years). After the individuals were randomly divided into two groups, static stretching was administered to the hamstring muscles in the first group and the Mulligan TSLR technique was administered on the same muscle in the second group. Active knee extension angles of the individuals were evaluated by a digital goniometer and muscle strain was assessed by ultrasound elastography. RESULTS: While there was a significant difference in all parameters in both groups after the treatment, the changes in the active knee extension angle and the strain index value of the biceps femoris musculotendinous junction were higher in the Mulligan TSLR group compared to the static stretching group (p < 0.05). CONCLUSION: It was concluded that, static stretching and the Mulligan TSLR technique administered to the hamstring muscles are effective ways to increase the range of motion. The Mulligan TSLR technique, however, can be opted in healthy individuals and patients since it is painless and more effective in reducing muscle resistance to movement and range of motion.

Are Perineal Massage and Instrument-Assisted Perineal Stretching With Short Protocol Effective for Increasing Pelvic Floor Muscle Extensibility? A Randomized Controlled Trial.

OBJECTIVE: The purpose of this study was to compare (1) the effects of the instrument-assisted perineal stretching technique with different application protocols in combination with perineal massage and (2) the effects of the isolated techniques on the extensibility and strength of the pelvic floor muscles (PFMs). METHODS: A randomized controlled clinical trial with parallel randomization, assessor blinding, and concealed allocation was conducted in the Campus Physical Education at the Federal University of Uberlândia in Brazil. Ninety-six pregnant women (18-40 years of age) were allocated into 4 groups: perineal massage (PnM) group (PnM protocol for 10 minutes); instrument-assisted perineal stretching with a long static protocol for 15 minutes [IStrLS group]); PnM + IStrLS group (both techniques applied in the 2 previous groups); and PnM + IStrSR group (the same techniques as used in the PnM + IStrLS group but with a short repeated protocol; 4 sets lasting 30 seconds each). Eight interventions were performed in all 4 groups twice weekly (beginning at the 34th gestational week). The primary outcome was PFM extensibility, assessed using vaginal dilator circumference, and the secondary outcome was PFM strength, assessed using vaginal manometry. RESULTS: For the PFM extensibility variable, a significant main effect of time (F2,88 = 87.951) and group (F3,88 = 7.193) was found. Tukey post hoc test results showed that the PnM + IStrSR group presented greater extensibility than the PnM and IStrLS groups. The PnM group showed increased PFM strength after 8 sessions compared with the other groups. CONCLUSIONS: Women who were pregnant and received the combination of perineal massage and instrument-assisted perineal stretching with short repeated application had a greater increase in PFM extensibility than perineal massage and instrument-assisted perineal stretching alone. IMPACT: The combination of perineal massage and instrument-assisted perineal stretching techniques with a short, repeated protocol led to better PFM extensibility results than the application of the techniques alone in women who were pregnant. LAY SUMMARY: Pregnant women can benefit from intervention using the combination of perineal massage and instrument-assisted perineal stretching techniques with a short, repeated protocol.

Triceps surae muscle-tendon unit mechanical property changes during 10 minutes of streching.

OBJECTIVE: To verify the effect of 10-min static stretching on the triceps surae mechanical properties. DESIGN: Quasi-experimental one-group pre test-post test study compared the time points of before, after, and minute by minute of one session of triceps surae passive static stretching. METHODS: 15 participants performed a 10-min plantar flexor passive static stretching on the isokinetic dynamometer. We evaluated passive torque and myotendinous junction (MTJ) displacement before, minute by minute, and after the intervention. In contrast, we evaluated the range of motion (ROM), passive torque, MTJ displacement, and hysteresis before and after the intervention. Paired t-test compared pre and post-intervention time points. Passive torque and MTJ displacement in the minute-by-minute evaluations were compared by repeated measures one-way ANOVA with a Bonferroni post-hoc test. RESULTS: ROM increased (effect size d = 0.56) and passive torque and muscle-tendon unit stiffness decreased (effect size d = 0.65 and d = 0.73, respectively) post-stretching. There was a reduction only in passive torque in the minute-by-minute evaluation, mainly at minutes five and seven. CONCLUSIONS: passive torque decreased over a 10-min static stretching session of the ankle plantar flexors, followed by a ROM increase and muscle-tendon unit, a stiffness decrease.

Comparison of Pelvic Tilt Before and After Hip Flexor Stretching in Healthy Adults.

OBJECTIVE: The purpose of this study was to assess the association between hip flexor length and pelvic tilt or lumbar lordosis by quantifying the effect of stretching on pelvic tilt and lumbar lordosis. METHODS: We quantified pelvic tilt and lumbar lordosis before and after a single session of passive hip flexor stretching in a sample of 23 male participants. Changes in hip flexor length were also characterized, using a Thomas test protocol to measure passive hip extension in supine lying. We investigated both the mean effect of the stretching protocol and potential correlations between changes in passive hip extension and changes in pelvic tilt or lumbar lordosis. RESULTS: Following the stretching protocol, there was a mean increase of 2.6° (P < .001) in passive hip extension and a corresponding mean reduction of 1.2° (P < .001) in anterior pelvic tilt. However, there was no change in lumbar lordosis, nor were there any meaningful correlations between change in passive hip extension and change in pelvic tilt or lumbar lordosis. CONCLUSION: The results suggest that hip muscle stretching may lead to immediate reductions in pelvic tilt during relaxed standing. Such stretching programs could play an important role in interventions designed to improve standing postural alignment.

Effects of 2 Intersection Strategies for Physical Recovery in Jiu-Jitsu Athletes.

PURPOSE: To compare the effect of static stretching (SS) and cold-water immersion (CWI) on strength performance and blood lactate levels of jiu-jitsu athletes. METHODS: A total of 21 male Brazilian jiu-jitsu fighters were randomly assigned to SS (9 × 30-s carpal extension), CWI (3 × 3 min at 10°C), or a control group (CG); their maximal handgrip strength, handgrip muscle endurance, dynamic kimono grip strength test, and blood lactate concentration were assessed before and after a simulated Brazilian jiu-jitsu fight and after one of the recovery interventions. RESULTS: There was an interaction (F = 9.075; P = .002) and a time effect (F = 11.792; P = .003) for dynamic kimono grip strength test, showing a decrease in performance for the CG (P = .0001; effect size [ES] = 0.52, moderate) and after SS (P = .006; ES = 0.43, small). There was an interaction (F = 3.592; P = .015) and a time effect (F = 122.631; P = .0001) for blood lactate concentration, showing lower levels after CWI versus CG (P = .028; ES = 0.93, moderate) and after CWI versus SS (P = .042; ES = 0.82, moderate). There was an interaction (F = 9.617; P = .001) for handgrip strength, showing an impairment in performance after SS (P = .001; ES = 0.67, moderate). CONCLUSION: CWI promoted restoration of muscle strength and endurance and reduction in blood lactate levels after the simulated fight and can thus be used by jiu-jitsu athletes as a recovery strategy between fights.

Contract-relax technique compared to static stretching in treating migraine in women: A randomized pilot trial.

INTRODUCTION: Physical therapy is often used by patients with headache, including modalities such as muscle stretching exercises. OBJECTIVES: To evaluate the feasibility of a pilot trial aimed at determining the efficacy of the proprioceptive neuromuscular facilitation (PNF) contract-relax technique compared to static stretching for treating migraineurs. METHODS: This pilot trial allocated 30 migraineur women (23 ±â€¯4 years) into PNF (n = 15) and static stretching groups (n = 15). The interventions were performed twice a week (16 sessions, 8 weeks). The feasibility outcomes included successful random allocation of 30 patients during a 12-month period, the proportion of eligible patients randomly assigned to each group, and the proportion of those who completed the 30-day follow-up. The outcomes of headache characteristics; medication intake; severity of migraine-related disability; neck disability; cervical mobility; pressure pain threshold; adverse effects and global perception of change were evaluated at baseline, after the end of treatment and after 30-day follow-up. RESULTS: The recruitment rate was 4.66% participants/month. The proportion of eligible patients randomly assigned to each group and for those who completed the 30-day follow-up was 88.23% and 100%, respectively. Both groups improved in headache-related outcomes. The perception of change was important for 67% of the PNF group and 47% of the static stretching group. No differences were found between groups regarding the studied outcomes. CONCLUSION: This is a feasible pilot trial. The PNF contract-relax technique was no more effective than static stretching for treating migraine, but both techniques improved the headache, the severity of migraine-related disability and the satisfaction after treatment.

Hold-relax and contract-relax stretching for hamstrings flexibility: A systematic review with meta-analysis.

OBJECTIVE: To synthesize evidence on the effects of hold-relax and contract-relax stretching (HR and CR) on hamstrings flexibility compared with no intervention and other stretching techniques. DESIGN: Electronic databases (PubMed, PEDro, Cochrane CENTRAL, Scopus, LILACS) were searched from inception until March 31, 2014 and updated until May 31, 2017. Randomized controlled trials involving HR and CR to improve hamstrings flexibility in adults (aged ≥18 years old) with or without a pathological condition were included. Two reviewers independently searched literature, assessed risk of bias, and extracted data, while a third reviewer settled disagreements. RESULTS: Thirty-nine trials (n = 1770 healthy adults; median PEDro score = 4/10) were included. Meta-analysis showed large effects compared to control immediately after 1 session (6 trials, SMD = 1.02, 95% CI = 0.69 to 1.35, I2 = 2%) and multiple sessions (4 trials, SMD = 1.02, 95% CI = 0.64 to 1.40, I2 = 0%). Meta-analysis showed conflicting results compared to static stretching, while individual trials demonstrated conflicting results compared to other techniques. CONCLUSIONS: The immediate effects of HR and CR on hamstrings flexibility in adults are better against control. The long-term effects against other stretching types, and optimal exercise prescription parameters require further research.

Efficacy of proprioceptive neuromuscular facilitation compared to other stretching modalities in range of motion gain in young healthy adults: A systematic review.

The objective of this study was to evaluate the efficacy of proprioceptive neuromuscular facilitation (PNF) on range of motion (ROM) gain in young healthy adults. We performed a systematic review of randomized controlled trials and quasi-randomized trials, including young healthy adults. The interventions were: PNF compared with different PNF techniques, control, other muscle stretching exercises and musculoskeletal manipulations. The outcome measures were: articular ROM and adverse effects. The final number of included studies was 46, involving 1,864 adults. There was difference on ROM comparing assisted hold-relax (HR) on diagonal plane to control, based on very low-quality evidence. There was also difference on ROM comparing assisted HR to self-HR; self-contract-relax (CR) to control; assisted CR contract to control; and assisted HR contract to control, based on low-quality evidence. Moderate-quality evidence shows that results differ between self HR and control (SMD: 0.95; 95%CI 0.03, 1.86; I249%; P = 0.16) in terms of ROM gain. When performing the other comparisons, the results were based on low or very low-quality evidence and do not allow to state if PNF is more or less effective than other stretches for improving ROM in healthy young adults. No adverse effects were mentioned.

Effects of perineal preparation techniques on tissue extensibility and muscle strength: a pilot study.

INTRODUCTION AND HYPOTHESIS: Perineal preparation techniques for childbirth have been used with the aim of reducing perineal tears during the expulsive phase of labor. However, no studies were found to investigate the effects of instrument-assisted stretching versus perineal massage on pelvic floor muscle (PFM) variables. Therefore, the aim of this study was to evaluate the effect of instrument-assisted stretching versus perineal massage on the extensibility and strength of the PFMs. METHODS: Primiparous women were randomized to the instrument-assisted stretching (IStr) group (n = 13) and perineal massage (PnM) group (n = 14). The groups participated in eight sessions, twice weekly, beginning at the 34th gestational week. The IStr group underwent the intervention for 15 min using EPI-NO®. The PnM group underwent a perineal massage protocol for 10 min. Each woman was evaluated by a blinded physiotherapist before, after four and after eight sessions for primary (PFM extensibility using the EPI-NO® circumference) and secondary (PFM strength using a manometer) outcomes. Covariate analysis (ANCOVA) was used to compare the groups using the baseline values as a covariate. RESULTS: Both groups showed an increase in PFM extensibility compared with the evaluations before and after four and eight sessions (PnM group from 17.6 ± 1.8 to 20.2 ± 1.9 cm; IStr group from 19.9 ± 1.6 to 22.9 ± 1.6 cm;p < 0.001). There was no difference between groups. Regarding muscle strength, no statistical differences were observed between evaluations or between groups. CONCLUSIONS: Instrument-assisted stretching and perineal massage increase extensibility and do not alter the strength of PFMs in pregnant women.

The Effect of Pelvic Floor Muscle Training On Incontinence Problems After Radical Prostatectomy.

The aim of the current study was to determine the effect of pelvic floor muscle exercises (PFME/Kegel) training administered to patients scheduled for robot-assisted radical prostatectomy on postprocedural incontinence problems. This study was a randomized controlled trial. Pelvic floor muscle exercises were applied to the procedure group three times a day for 6 months. No exercises were applied to the control group. Incontinence and quality-of-life assessments of the 60 patients in the experimental and control groups were performed on months 0 (10 days after removal of the urinary catheter), 1, 3, and 6 through face-to-face and telephone interviews. Total Incontinence Consultation on Incontinence-Short Form scores, which provide an objective criterion for the evaluation of individuals with incontinence problems, decreased over time. This decrease was statistically highly significant in the third and sixth months. Pelvic muscle floor exercises are suitable for patients experiencing incontinence after radical prostatectomy.

Concurrent Criterion-related Validity, Reliability, and Responsiveness to Treatment of the Figure-of-Four Position for Measurement of Anterior Hip Joint Structures Tightness.

OBJECTIVE: The objective of this study was to examine the intra- and intertester reliability, concurrent criterion-related validity, and responsiveness to treatment of the "figure-of-four" position. METHODS: A total of 52 asymptomatic male soccer players participated in this study. The intraclass correlation coefficient (2, 1) was used to determine intra- and intertester reliability of the figure-of-four position. Pearson product moment correlation coefficients examining the association between the figure-of-four position and goniometric measurements of hip extension and external rotation were used to establish concurrent validity. To evaluate responsiveness to treatment, the figure-of-four position was assessed by a blinded examiner before and immediately after the application of a stretching technique or control intervention. RESULTS: Excellent reliability (intraclass correlation coefficient > 0.75) was obtained for both intra- and intertester reliability of the figure-of-four position. Overall, the figure-of-four position and goniometric measurements of both hip extension and external rotation were significantly correlated. However, no significant treatment effects were observed for the figure-of-four position. CONCLUSION: The results of this study demonstrated that the figure-of-four position is a reliable and valid way to obtain information on tightness of anterior hip joint structures in male soccer players. However, responsiveness to treatment of the figure-of-four position should be questioned.

[Insertional Achilles tendinopathy : Differentiated diagnostics and therapy]. / Ansatznahe Erkrankungen der Achillessehne : Differenzierte Diagnostik und Therapie.

Achilles tendinopathy at the calcaneal insertion is classified into insertional tendinopathy, retrocalcaneal and superficial bursitis. The aim of this study was to present the current evidence on conservative and surgical treatment of insertional tendinopathy of the Achilles tendon. Conservative first-line therapy includes reduction of activity levels, administration of non-steroidal anti-inflammatory drugs (NSAID), adaptation of footwear, heel wedges and orthoses or immobilization. In addition, further conservative therapy options are also available. Eccentric stretching exercises should be integral components of physiotherapy and can achieve a 40% reduction in pain. Extracorporeal shock wave therapy has been shown to reduce pain by 60% with a patient satisfaction of 80%. Due to the limited evidence, injections with platelet-rich plasma (PRP), dextrose (prolotherapy) or polidocanol (sclerotherapy) cannot currently be recommended. Operative therapy is indicated after 6 months of unsuccessful conservative therapy. Open debridement allows all pathologies to be addressed, including osseous abnormalities and intratendinous necrosis. The success rate of over 70% is contrasted by complication rates of up to 40%. The Achilles tendon should be reattached, if detached by >50%. No valid data are available for the transfer of the tendon of the flexor hallucis longus (FHL) muscle but it is frequently applied in cases of more than 50% debridement of the diameter of the Achilles tendon. Lengthening of the gastrocnemius muscle cannot be recommended because insufficient data are available. Tendoscopy is a promising treatment option for isolated retrocalcaneal bursitis and has shown similar success rates to open debridement with significantly lower complication rates.

Método Isostretching em ambiente aquático e a melhora da flexibilidade muscular de idosos / Positive effect of isostretching in aquatic environment on muscle flexibility in elderly people

Introdução: Com o avançar da idade ocorre redução da flexibilidade devido à insuficiente atividade do sistema neuromuscular, ao desuso da musculatura esquelética e à diminuição do condicionamento físico, contribuindo para a redução da autonomia e da capacidade de realizar atividades cotidianas. Objetivo: Avaliar os efeitos do método Isostretching em ambiente aquático na flexibilidade muscular de idosos. Métodos: Estudo longitudinal, quase experimental, não controlado, desenvolvido com 26 indivíduos de ambos os gêneros, com média de idade de 67,5 ± 7 anos, avaliados em relação à flexibilidade de membros inferiores, por meio do teste de "sentar e alcançar" realizado pré e pós-aplicação, por 12 semanas, do método Isostretching em ambiente aquático. A normalidade da amostra foi aferida por meio do teste Shapiro Wilk e os resultados obtidos antes e após o método foram comparados por meio do teste Wilcoxon, considerando p < 0,05. Resultados: Ao comparar os resultados, foi possível constatar que ocorreu melhora significativa (p < 0,05) na flexibilidade de cadeia posterior de membros inferiores do grupo estudado, sendo esta de 12,5 cm. Conclusão: O método Isostretching, quando realizado em ambiente aquático, foi capaz de melhorar a flexibilidade de cadeia posterior de membros inferiores de idosos.

Introduction: Flexibility reduces with age due to insufficient activity of the neuromuscular system, disuse of the skeletal muscles, and a lack of physical conditioning, therefore resulting in decreased autonomy and inability to perform daily activities. Objective: To evaluate the effects of Isostretching in aquatic environment on muscle flexibility of elderly people. Methods: A longitudinal, nearly experimental, uncontrolled study conducted with 26 individuals of both sexes, average age 67.5 ± 7 years, evaluated in terms of lower limb flexibility through the "sit and reach" test before and after a 12-week session of Isostretching in aquatic environment. The sample was tested for normality using the Shapiro-Wilk test, and the pre and post practice results were compared using the Wilcoxon test, considering p < 0.05. Results: When comparing pre and post results of Isostretching in aquatic environment, a significant improvement (p < 0.05) was observed in the posterior chain flexibility (12.5 cm) of lower limbs in the studied group. Conclusion: Isostretching performed in aquatic environment improved the posterior chain flexibility of lower limbs in a group of elderly people.

Clinical Effects of Dry Needling Among Asymptomatic Individuals With Hamstring Tightness: A Randomized Controlled Trial.

STUDY DESIGN: Randomized controlled trial. OBJECTIVES: The aim of this study was to determine the effects of dry needling on hamstring extensibility and functional performance tests among asymptomatic individuals with hamstring muscle tightness. BACKGROUND: Dry needling has been shown to increase range of motion in the upper quarter and may have similar effects in the lower quarter. METHODS: 27 subjects with hamstring extensibility deficits were randomly assigned to side of treatment (dominant or nondominant) and group (blunt needling or dry needling). The first session included measurement of hamstring extensibility and performance on 4 unilateral hop tests, instruction in home hamstring stretching exercises and needling distal to the ischial tuberosity and midbellies of the medial and lateral hamstrings. A second session, 3-5 days following the first session, included outcome measures and a second needling intervention, and a third session, 4-6 weeks following the first session, included outcome measures only. A 2 × 3 × 2 ANOVA was used to statistically analyze the data. RESULTS: Hamstring extensibility showed a significant side × time interaction (P < .05). The single hop for distance, timed 6-meter hop, and the crossover hop test had a significant main effect of time (P < .05). The triple hop for distance showed a significant side × time × group interaction (P < .05). CONCLUSIONS: It does not appear dry needling results in increased extensibility beyond that of stretching alone in asymptomatic individuals. Our study findings suggest that dry needling may improve certain dimensions of functional performance, although no clear conclusion can be made. LEVEL OF EVIDENCE: Intervention, level 2b.
