Amigos de Fibro (Fibro Friends): validation of an e-book to promote health in fibromyalgia.

BACKGROUND: Educational strategies are necessary for the care of patients with fibromyalgia. The objective was to develop and validate an e-book to promote the health of individuals with fibromyalgia. METHODS: Methodological research in which, initially, through a bibliographic survey, the available publications on the subject were analyzed. Then, this knowledge was used to build the theoretical content addressed, and the art and layout of the e-book were elaborated. In the third phase, validation of the constructed material, content specialists (n = 23), technicians (n =  23) and design specialists (n = 23), and individuals with fibromyalgia (n = 45) evaluated the e-book through the Delphi technique. For data collection, different questionnaires were used, according to the evaluation focus of each participant group, analyzed for reliability using Cronbach's Alpha (αC) and agreement using the Content Validity Index (CVI). RESULTS: In the global assessment of agreement from all groups of judges, the CVI presented a considerable minimum: content (0.79), technical (0.89), design (0.92), and target audience (0.97). Regarding reliability, all groups also had a αC within the acceptable range: content (0.960), technical (0.963), design (0.977), and target audience (1.08). CONCLUSIONS: The e-book was developed and validated in terms of content and relevance and can be used to promote the health of individuals with fibromyalgia.

Hip abductor versus adductor strengthening for clinical outcomes in knee symptomatic osteoarthritis: A randomized controlled trial.

BACKGROUND: Hip adductors and abductors are weak in patients with knee osteoarthritis (KOA). However, most studies have not investigated selective adductor strengthening. OBJECTIVE: To compare the effects of adding selective hip abductors versus adductors strengthening to lower limb multimodal exercise program for pain, self-reported function, knee-related quality of life, medication ingested and performance-based tests in patients with symptomatic KOA. DESING: Randomized controlled trial. METHODS: Sixty-six patients with KOA were randomly assigned to two treatment groups: hip abductor group (HABG) or hip adductor group (HADG). Both groups performed a lower limb multimodal exercise program. HABG and HADG groups added three hip abduction and three hip adduction exercises, respectively. Intensity of pain through numeric pain scale, Knee Injury and Osteoarthritis Outcome Score (KOOS) subscales, Lequesne questionnaire, global perceived effect scale, medication ingested, performance-based tests were assessed at baseline, after 6 weeks, and 6 months. RESULTS: No significant between-group differences were found in primary outcomes: pain intensity (mean difference = -1.15, 95%CI -2.44 - 0.12, P = 0.07), KOOS-pain (mean difference = 1.64, 95%CI -6.79 - 10.07, P = 0.70) and KOOS-function in daily living (mean difference = -0.12, 95%CI, -8.78 - 8.54, P = 0.97) in 6 weeks. Groups did not differ in any secondary outcome after 6 weeks or after 6 months (P > 0.05). CONCLUSIONS: There is no difference between adding hip abductors or adductors strengthening to lower limb multimodal exercise program in improving pain, self-reported function, quality of life, medication ingested and performance-based tests in patients with KOA.

Low Back Pain in Elderly from Belém-Pa, Brazil: Prevalence and Association with Functional Disability.

BACKGROUND: This cross-sectional study aimed to determine the prevalence of low back pain (LBP) in the elderly population living in Belém-Pará and to assess the spectrum of problems related to these diseases including the demographic, socioeconomic, occupational characteristics and disability in this population. METHODS: Three structured questionnaires were applied in a randomly selected representative sample of 512 elderly people aged ≥60 years. RESULTS: LBP prevalence in the elderly population was 55.7%. Among then, 56.1% had pain at the time of the interview (punctual prevalence), 91.7% had LBP in the last 365 days (prevalence in the last year), and 85.3% at some point in life (prevalence at some point in life). Overall, most studies are above average. LBP was positively associated with hypertension and the influence of the physical and mental health on their social activities ranged from slightly to extreme. LBP was negatively associated with characteristics, such as education (over 11 years), class A or B income, physical activity, high satisfaction with previous work, and excellent self-perceived health, corroborating to the literature. CONCLUSIONS: Greater intensity of pain and functional disability were associated with the presence of comorbidities, smoking habits, and low physical activity. LBP prevalence was high, above the national average, mainly affecting the underprivileged classes related to several modifiable factors, highlighting the importance of preventive and interventionist actions for healthy aging.

Effects of electroacupuncture frequencies on chronic low back pain in older adults: triple-blind, 12-months protocol for a randomized controlled trial.

BACKGROUND: Low back pain (LBP) is the most frequent complaint in clinical practice. Electroacupuncture treatment may be effective; however, the supporting evidence is still limited, especially in older adults. OBJECTIVE: The current study is a randomized controlled trial that aims to evaluate the clinical efficacy of electroacupuncture in older adults with LBP. METHODS: A five-arm randomized controlled trial with patients and evaluators blinded to the group allocation. A total of 125 participants with non-specific LBP will be randomly assigned into one of five groups: three electroacupuncture groups (low, high, and alternating frequency); one control group; and one placebo group. The electroacupuncture will be applied twice a week (30 min per session) for five weeks. The primary clinical outcome measure will be pain intensity. The secondary outcomes include: quality of pain; physical functioning; perceived overall effect; emotional functionality; patient satisfaction; and psychosocial factors. Patients will be evaluated before the first session, immediately after the last, and followed up after six and 12 months to check the medium- and long-term effects. DISCUSSION: Although electroacupuncture is increasingly used to treat LBP, there is no guidance regarding the parameters used, which leads to inconsistent results. Thus, the effect of electroacupuncture (EA) on LBP remains controversial and requires more studies, especially in the older adult population. CONCLUSION: This is the first randomized controlled trial to evaluate the efficacy of different frequencies of electroacupuncture for treating chronic LBP in older adults. This study will provide evidence on the effectiveness of electroacupuncture as an alternative treatment method for LBP and will entail wider debate about an appropriate acupuncture intervention in this population.

Reliability in Mandibular Movement Evaluation Using Photogrammetry in Patients With Temporomandibular Disorders.

OBJECTIVE: The purpose of this study was to propose a quantitative evaluation for mandibular opening-closing movement asymmetries and to verify the intraexaminer and interexaminer reliability using photogrammetry in individuals with and without myogenic temporomandibular disorders. METHODS: Forty-nine female participants between ages 18 and 40 were enrolled in this study. They were assigned to 2 different groups: a temporomandibular disorder group, (n = 25; 28.1 ± 3.6 years) and an asymptomatic group (n = 24; 25.6 ± 5.1 years). Data were collected through photogrammetry using Corel Draw X3 software (Corel Corp, Ottawa, Ontario, Canada) for angle measurements. Reliability analysis was done on the total sample, and the photographs were obtained by a singular examiner on 2 occasions (intraexaminer) 1 month apart and from measurement made by another examiner (interexaminer) on different days. The intraclass correlation coefficient (ICC) was applied with a significance level of 5%. RESULTS: The photogrammetry had excellent intrarater and inter-rater reliability for the evaluation of opening and closing movements of the jaw (intrarater: opening ICC = 0.99; closing ICC = 0.98; inter-rater: opening ICC = 0.89 and closing ICC = 0.82). Photogrammetry also demonstrated excellent intra- and inter-rater reliability in the evaluation of head posture (intra-rater: head deviation ICC = 0.96; head position ICC = 0.75; inter-rater: head deviation ICC = 0.98; head position ICC = 0.98). CONCLUSION: Under these experimental conditions, most angular values presented excellent intra- and interexaminer reliability.

Effectiveness of Aquatic Therapy vs Land-based Therapy for Balance and Pain in Women with Fibromyalgia: a study protocol for a randomised controlled trial.

BACKGROUND: Fibromyalgia is a disease with an increasing incidence. It impairs the quality of life of patients and decreases their functional capacity. Aquatic therapy has already been used for managing the symptoms of this syndrome. However, aquatic therapy has only recently been introduced as a treatment modality for improving proprioception in fibromyalgia. The main objective of this study is to determine the effectiveness of two physiotherapy protocols, one in and one out of water, for improving balance and decreasing pain in women with fibromyalgia. METHODS/DESIGN: The study protocol will be a single-blind randomised controlled trial. Forty women diagnosed with fibromyalgia will be randomly assigned into 2 groups: Aquatic Therapy (n = 20) or Land-based Therapy (n = 20). Both interventions include 60-min therapy sessions, structured into 4 sections: Warm-up, Proprioceptive Exercises, Stretching and Relaxation. These sessions will be carried out 3 times a week for 3 months. Primary outcomes are balance (static and dynamic) and pain (intensity and threshold). Secondary outcomes include functional balance, quality of life, quality of sleep, fatigue, self-confidence in balance and physical ability. Outcome measures will be evaluated at baseline, at the end of the 3-month intervention period, and 6-weeks post-treatment. Statistical analysis will be carried out using the SPSS 21.0 program for Windows and a significance level of p ≤ 0.05 will be used for all tests. DISCUSSION: This study protocol details two physiotherapy interventions in women with fibromyalgia to improve balance and decrease pain: aquatic therapy and land-based therapy. In current literature there is a lack of methodological rigour and a limited number of studies that describe physiotherapy protocols to manage fibromyalgia symptoms. High-quality scientific works are required to highlight physiotherapy as one of the most recommended treatment options for this syndrome.

Dynamic postural stability and muscle strength in patellofemoral pain: Is there a correlation?

BACKGROUND: Although females with patellofemoral pain (PFP) show a decrease in hip and knee muscle strength, there is a lack of studies that associates this with postural stability. The purpose of this study was to assess the dynamic postural stability and muscle strength in the hips and knees of females with and without PFP, and to verify the association between the postural stability and the muscle strength in the PFP group. METHODS: Two groups were tested: one with 25 PFP and one with 25 asymptomatic. Postural stability was evaluated during stepping up down tasks using a force platform to determine the center of pressure (COP) excursion and velocity. A handheld dynamometer was used to assess the muscles strength. The correlation analysis was conducted between the COP variables and the muscle strength. RESULTS: The PFP group demonstrated greater total and medial-lateral COP displacement (8887.7±761.7 vs. 8129.4±691.9mm, P<0.001; 32.3±5.5 vs. 21.7±2.7mm, P<0.001) and a higher total of medial-lateral COP velocity (22.2±5.2 vs. 17.0±1.6 P=0.001). The PFP group showed weaknesses in all muscles (P<0.05), and there was a good positive correlation between the anterior-posterior displacement and the velocity of the extensor hip muscle (r=0.52, P<0.01; r=0.55, P<0.001). CONCLUSIONS: Subjects with PFP have frontal dynamic postural stability deficit and show an association between hip extensor and sagittal plane stability.

Efficacy of acupuncture and electroacupuncture in patients with nonspecific low back pain: study protocol for a randomized controlled trial.

BACKGROUND: Previous studies have shown that acupuncture and electroacupuncture (EA) are effective in the treatment of patients with low back pain. However, there is little evidence to support the use of one intervention over the other. The aim of this study is to compare the effect of acupuncture and electroacupuncture in the treatment of pain and disability in patients with chronic nonspecific low back pain. METHODS/DESIGN: The study design is a randomized controlled trial. Patients with nonspecific chronic low back pain of more than three months duration are recruited at Rehabilitation Center of Taboao da Serra - SP (Brazil). After examination, sixty-six patients will be randomized into one of two groups: acupuncture group (AG) (n = 33) and electroacupuncture group (EG) (n = 33). Interventions will last one hour, and will happen twice a week for 6 weeks. The primary clinical outcomes will be pain intensity as measured and functional disability. SECONDARY OUTCOMES: quality of pain, quality of life. perception of the overall effect, depressive state, flexibility and kinesiophobia. All the outcomes will be assessed will be assessed at baseline, at treatment end, and three months after treatment end. Significance level will be determined at the 5 % level. Results of this trial will help clarify the value of acupuncture and electroacupuncture as a treatment for chronic low back pain and if they are different. DISCUSSION: Results of this trial will help clarify the value of acupuncture needling and electroacupuncture stimulation of specific points on the body as a treatment for chronic low back pain.

Effect of low-level laser therapy (904 nm) and static stretching in patients with knee osteoarthritis: a protocol of randomised controlled trial.

BACKGROUND: Osteoarthritis (OA) is a highly prevalent and disabling disease. It is estimated that by 2030 the prevalence of symptomatic OA could reach 30 % of the population above 60 years. This randomised controlled trial will investigate the effect of low-level laser therapy (LLLT) and static stretching exercises, as monotherapy and in combination, on pain, quality of life, function, mobility, knee range of motion (KROM) and hamstring shortening in participants with knee OA. METHODS: This study will involve 145 people aged 50-75 years with symptomatic-radiographic knee OA. It will consist of two types of treatments: Low-level laser therapy (LLLT) and stretching exercises. The patients will be randomly allocated to five groups LLLTACTIVE+Stretch, LLLTPLACEBO+Stretch, Stretch, LLLT and Control (n = 29 each). Treatment frequency will be three sessions/week for all active groups. LLLT will involve the use of a Gallium-Arsenide laser (904 nm, 40 milliwatts, 3 J/point, 27 J/knee) over 24 sessions for the monotherapy group and 9 sessions for the LLLT+Stretch groups. Stretching will consist of seven exercises completed over 24 sessions. The control group will receive a booklet. Participants will be treated for 2 months (Stretch, LLLT and Control groups) or 3 months (LLLT + Stretch groups). Participants and the outcome assessor will be blind to treatment allocation throughout the study. The primary outcome is pain measured by Visual Analogue Scale. Secondary outcomes include quality of life assessed by Western Ontario and McMaster Universities Arthritis Index, function by Lequesne Algofunctional Index, mobility by Timed Up and Go Test, KROM by goniometry of knee flexion and hamstring shortening by popliteal angle. The statistical method will follow the principles of per-protocol analysis. DISCUSSION: Although exercise therapy is considered an effective treatment in patients with knee osteoarthritis, the knowledge of which exercise modalities would be the most appropriate for this population is lacking. LLLT has been used as resource to increase the effects of physical therapy. However, the specific dose and treatment frequency need to be better defined. The findings from this randomised controlled trial will provide evidence of the efficacy or otherwise, of LLLT and stretching exercises in the management of knee OA symptoms.
