Photobiomodulation Before Eccentric Fatigue Protocol in the Control of Pain and Muscle Damage Markers: A Double-Blind, Randomized Controlled Study.

Background: Several strategies are used in the management of delayed-onset muscle soreness (DOMS), but there is not always evidence to justify its use. Photobiomodulation (PBM) is a noninvasive means, with promising previous results of its use in this outcome. Objective: This study aimed to identify the effects of PBM in the femoral quadriceps region to reduce DOMS in men undergoing a fatigue protocol. Methods: This is a double-blind, randomized controlled study. The sample consisted of 35 physically active men. The volunteers were divided into two groups: pre-fatigue PBM [Group 1 (G1)] and post-fatigue PMB [Group 2 (G2)]. The fatigue test was conducted at the same time of day. Given this was a crossover study of volunteers, we used at least a 1-week washout to avoid any residual interference from the previous intervention. PBM (active/placebo) was performed 5 min before the start of the fatigue protocol in G1 and immediately after the fatigue protocol in G2. PBM was applied at six points on the femoral quadriceps muscle (cluster laser/light emitting diodes 13, 415 mW, 30.2 J per point, 73 sec per application, and total dose of 181.2 J). In the data analysis, the primary endpoint was DOMS measured using a Numerical Pain Scale, and the secondary outcome was examined on the effects of PMB muscle damage, muscle contraction, and isometric horizontal jump. Results: There were significant differences to PBM compared with the placebo group for DOMS, with no differences between the times of application. For muscle damage, there was significant difference (p > 0.05) when PBM was applied in pre-fatigue. G1 led to an increase of 14.9% in the creatine kinase level when active since the application of placebo PBM increased by 65% (p = 0.04). Conclusions: The PBM applied before eccentric fatigue protocol showed no significant results on DOMS, although there was a positive effect to control muscle damage.

What do Cochrane Systematic Reviews say about conservative and surgical therapeutic interventions for treating rotator cuff disease? Synthesis of evidence

ABSTRACT BACKGROUND: Shoulder pain is considered to be the third largest cause of musculoskeletal functional alterations in individuals presenting pain during movement. OBJECTIVE: The purpose of this synthesis of evidence was to identify the clinical effectiveness of conservative and surgical treatments reported in Cochrane systematic reviews among individuals diagnosed with rotator cuff disease. DESIGNAND SETTING: Review of systematic reviews, conducted in the Federal University of São Paulo (Universidade Federal de São Paulo, UNIFESP). METHODS: This synthesis of evidence included systematic reviews that had been published in the Cochrane database. The inclusion criteria were that these systematic reviews should involve individuals aged ≥ 16 years with rotator cuff disease, comparing surgical procedures with or without associated nonsurgical procedures versus placebo, no treatment or other nonsurgical interventions. RESULTS: Thirty-one systematic reviews were included, involving comparisons between surgical procedures and conservative treatment; procedures either combined or not combined with drugs, versus other procedures; and procedures involving exercises, manual therapy and electrothermal or phototherapeutic resources. CONCLUSIONS: The findings suggest that strengthening exercises, with or without associated manual therapy techniques and other resources, were the interventions with greatest power of treatment over the medium and long terms, for individuals with shoulder pain. These had greater therapeutic power than surgical procedures, electrotherapy or photobiomodulation. Protocol registration number in the PROSPERO database: ID - CRD42018096578.

Evidence synthesis of types and intensity of therapeutic land-based exercises to reduce pain in individuals with knee osteoarthritis.

The objective of this study is to construct an evidence synthesis to identify the types of land-based exercises most investigated in the current literature, the intervention duration, frequency of the programs and the exercises which are most frequently implemented. A search was performed on the reference list of included and excluded studies of one systematic review, on land-based exercises for knee osteoarthritis and, an updated search of The Cochrane Library, Embase, CINAHL and PEDro was completed. Two authors independently selected the studies and a third author was consulted for an additional opinion. The inclusion criteria were male or female with tibiofemoral knee osteoarthritis, land-based exercises, non-exercise control group and randomized clinical trials. The exclusion criteria were mixed diagnosis or comparison to other types of exercise. The data were extracted by two authors. Fifty-five full-text articles were included. Strengthening, proprioception and aerobic exercises resulted in significant pain reduction. The intervention durations which were significant for pain reduction were either the period of 8-11 weeks or 12-15 weeks. The frequency of three times per week was found significant in comparison to a non-exercise control group. The results, which formed an evidence synthesis, demonstrate that there is substantial evidence regarding the benefits of strengthening exercises to reduce pain in knee osteoarthritis patients. Based on the included studies analysis, exercises should be performed three times weekly for a duration of 8-11 or 12-15 weeks. Health professionals working with knee osteoarthritis patients can use this evidence synthesis as a fast and pragmatic instrument to obtain information about several effective types of exercises for pain reduction.

The Effectiveness of the Comprehensive Voice Rehabilitation Program Compared With the Vocal Function Exercises Method in Behavioral Dysphonia: A Randomized Clinical Trial.

OBJECTIVE: To evaluate the effectiveness of the Comprehensive Voice Rehabilitation Program (CVRP) compared with Vocal Function Exercises (VFEs) to treat functional dysphonia. STUDY DESIGN: This is a randomized blinded clinical trial. METHODS: Eighty voice professionals presented with voice complaints for more than 6 months with a functional dysphonia diagnosis. Subjects were randomized into two voice treatment groups: CVRP and VFE. The rehabilitation program consisted of six voice treatment sessions and three assessment sessions performed before, immediately after, and 1 month after treatment. The outcome measures were self-assessment protocols (Voice-Related Quality of Life [V-RQOL] and Voice Handicap Index [VHI]), perceptual evaluation of vocal quality, and a visual examination of the larynx, both blinded. RESULTS: The randomization process produced comparable groups in terms of age, gender, signs, and symptoms. Both groups had positive outcome measures. The CVRP effect size was 1.09 for the V-RQOL, 1.17 for the VHI, 0.79 for vocal perceptual evaluation, and 1.01 for larynx visual examination. The VFE effect size was 0.86 for the V-RQOL, 0.62 for the VHI, 0.48 for the vocal perceptual evaluation, and 0.51 for larynx visual examination. Only 10% of the patients were lost over the study. CONCLUSIONS: Both treatment programs were effective. The probability of a patient improving because of the CVRP treatment was similar to that of the VFE treatment.

Effects of neuromuscular electrical stimulation combined with exercises versus an exercise program on the pain and the function in patients with knee osteoarthritis: a randomized controlled trial.

OBJECTIVES: To investigate the effect of 8 weeks of NMES + Ex (neuromuscular electrical stimulation combined with exercises) on pain and functional improvement in patients with knee osteoarthritis (OA) compared to exercise (Ex) alone. DESIGN: Randomized controlled trial. SETTING: A specialty outpatient clinic. PARTICIPANTS: Patients (N = 100; women = 86, men = 14; age range, 50-75 years) with knee OA. INTERVENTIONS: Participants were randomly assigned to NMES + Ex or Ex group. OUTCOME MEASURES: Numerical Rating Scale 0 to 10 (NRS) and the Timed Up and Go (TUG) test were the primary outcomes. The secondary outcomes used were the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). RESULTS: Following the interventions, a statistically significant improvement in both groups was observed in all outcomes assessed. For the comparison between the groups, no statistically significant difference was found between the NMES + Ex and the Ex groups in NRS (P = 0.52), TUG test (P = 0.12), and aspects of WOMAC: pain (P = 0.26), function (P = 0.23), and stiffness (P = 0.63). CONCLUSION: THE addition of NMES to exercise did not improve the outcomes assessed in knee OA patients. This study was registered at the Australian Clinical Trials Registry (ACTRN012607000357459).

Mandibular manipulation for the treatment of temporomandibular disorder.

The aim of this study was to conduct a systematic review to identify the randomized clinical studies that had investigated the following research question: Is the mandibular manipulation technique an effective and safe technique for the treatment of the temporomandibular joint disk displacement without reduction? The systematic search was conducted in the electronic databases: PubMed (Medical Publications), LILACS (Latin American and Caribbean Literature in Health Sciences), EMBASE (Excerpta Medica Database), PEDro (Physiotherapy Evidence Database), BBO (Brazilian Library of Odontology), CENTRAL (Library Cochrane), and SciELO (Scientific Electronic Library Online). The abstracts of presentations in physical therapy meetings were manually selected, and the articles of the ones that meet the requirements were investigated. No language restrictions were considered. Only randomized and controlled clinical studies were included. Two studies of medium quality fulfilled all the inclusion criteria. There is no sufficient evidence to support the effectiveness of the mandibular manipulation therapy, and therefore its use remains questionable. Being minimally invasive, this therapy is attractive as an initial approach, especially considering the cost of the alternative approaches. The analysis of the results suggests that additional high-quality randomized clinical trials are necessary on the topic, and they should focus on methods for data randomization and allocation, on clearly defined outcomes, on a priori calculated sample size, and on an adequate follow-up strategy.

Effectiveness of electrical stimulation on rehabilitation after ligament and meniscal injuries: a systematic review / Efetividade da estimulação elétrica na reabilitação pós-lesões ligamentares e meniscais: uma revisão sistemática

CONTEXT AND OBJECTIVE: Electrical stimulation (ES) is widely used to strengthen muscles following ligament and meniscal injuries. The aim of this study was to evaluate the effectiveness of ES for rehabilitation after soft tissue injuries of the knee treated surgically or conservatively. DESIGN AND SETTING: Systematic review at the Brazilian Cochrane Center. METHODS: We searched the Cochrane Central Register of Controlled Trials (2010, Issue 12), Medline (Medical Analysis and Retrieval System Online) via PubMed (1966 to December 2010), Embase (Excerpta Medica database, 1980 to December 2010), Lilacs (Literatura Latino-Americana e do Caribe em Ciências da Saúde, 1982 to December 2010), and PEDro (Physiotherapy Evidence Database, 1929 to December 2010). The studies included were randomized controlled trials using ES to increase muscle strength for rehabilitation of patients with soft tissue injuries of the knee. Two authors independently evaluated studies for inclusion and performed data extraction and methodological quality assessment. RESULTS: Seventeen studies evaluating ES after anterior cruciate ligament reconstruction and two studies evaluating ES after meniscectomy were included. There was a statistically significant improvement in quadriceps strength through ES (mean difference, MD: -32.7; 95 percent confidence interval, CI: -39.92 to -25.48; n = 56) and in functional outcomes (MD -7; -12.78 to -1.22; n = 43) six to eight weeks after surgical reconstruction of the anterior cruciate ligament. CONCLUSION: There is evidence that ES coupled with conventional rehabilitation exercises may be effective in improving muscle strength and function two months after surgery.

Mensuração da amplitude de movimento ativa do joelho intra e interavaliador com goniômetro e fl exímetro / Measurement of knee active range of motion intra and interobserverwith goniometer and fleximeter

Objetivo: Avaliar intra e interobservador a confi abilidade e areprodutibilidade do goniômetro e flexímetro na amplitude de movimento ativa do joelho. Desenho de estudo: Estudo transversal randomizado cego. Métodos: Participaram deste estudo 50 indivíduos de ambos os sexos (28 homens e 22 mulheres), com média de idade de 26,68 anos, peso de 68,69 kg e altura de 1,70 m. As mensurações da extensão e fl exão do joelho foram realizadas com o goniômetro e o flexímetro por dois avaliadores. Resultados: Em relação à flexão de joelho, pôde-se analisar que não houve concordância intra-avaliador (ICCs de 0,54 e 0,64) e houve uma concordância moderada interavaliador para os dois instrumentos (ICCs de 0,73 e 0,76). Também foi demonstrado que o goniômetro tende a apresentar resultados inferiores ao fl exímetro à medida que a fl exão do joelho aumenta. Em relação à extensão, pôde-se observar uma concordância muito forte tanto intra, como interavaliador (ICCs de 0,92 e 0,92). Conclusão: A fl exão do joelho não apresentou concordância intraavaliador e houve uma concordância moderada interavaliador. Para a extensão do joelho, houve uma concordância muito forte tanto intra quanto interavaliador.

Objective: To assess the intra- and interobserver reproducibility of goniometer and fl eximeter in the knee active range of motion. Design: double-blind randomized transversal study. Methods and measures: Fifty subjects of both genders participated in this study (28 male and 22 female), mean age 26.68 years, average weight 68.69 kg and average height 1.70 m. Knee extension and fl exion measurements were performed by two observers using a goniometer and a fl eximeter. Results: Knee fl exion did not show intra-observer agreement (ICCs of .54 and .64) and a moderate interobserver agreement was achieved by both instruments (ICCs of .73 and .76). Itwas also observed that the goniometer tends to present lower results than the fl eximeter in proportion to the increase of knee fl exion. In relation to extension, it could be observed a high rate intra andinterobserver agreement (ICCs of .92 and .92). Conclusion: Knee flexion did not show intra-observer agreement but showed moderate inter-observer agreement. For knee extension, there was a high rate of intra and inter-observer agreement.
