Inter-rater Accuracy and Reliability of a Palpation Protocol of the C7 Spinous Process Comprising a Combination of 3 Traditional Palpation Techniques.

OBJECTIVE: The purpose of this study was to determine the accuracy and intrarater reliability of a palpatory protocol based on a combination of 3 palpatory methods to identify both the C7 spinous process (C7 SP) and the factors that affect the errors and inaccuracy of palpation. METHODS: Twenty-five women between the ages of 18 and 60 years were submitted to a palpation protocol of the C7 SP, and a radiopaque marker was fixed on the skin at the possible location of the vertebrae. A radiograph and a photograph of the cervical spine were obtained in the same posture by a first rater. A second rater performed the same palpation protocol and took a second photograph. The accuracy and measurement error of the palpation protocol of C7 SP were assessed through radiographic images. The inter-rater reliability was estimated by the interclass correlation coefficient and assessed using photographs of each rater. The Pearson's correlation coefficients (r), the Fisher exact test, and the χ2 test were used to identify the factors associated with the error and inaccuracy of palpation. RESULTS: Accuracy of the C7 palpation was 76% with excellent reliability (interclass correlation coefficient = 0.99). There was a moderate correlation between weight and the measurement of palpation error (r = -0.6; P = .003). One hundred percent of inaccuracy palpation was related to the increased soft-tissue thickness (P = .005) in the cervical region. CONCLUSION: The palpation protocol described in this study was accurate and presented excellent reliability in identifying the C7 SP. Increased weight and dorsocervical fat pad were associated to error and palpation inaccuracy, respectively.

Resistance exercises improve physical function in chronic Chikungunya fever patients: a randomized controlled trial.

BACKGROUND: Chikungunya fever is an arboviral disease, caused by an alphavirus, the Chikungunya virus, characterized by fever and joint pain that is generally disabling in the acute phase and may last from months to years, with the potential to evolve into chronic musculoskeletal symptoms, as polyarthralgia and arthritis, which can lead to significant impairment of physical function. The non-pharmacological treatment is very important for these patients, and resistance exercises may be one rehabilitation option. AIM: This study aimed to evaluate the efficacy of a resistance exercise protocol on the physical function, pain, and quality of life of patients with chronic Chikungunya fever. DESIGN: A randomized, controlled, blind trial for the evaluators. SETTING: Clinic-school of Physical therapy. POPULATION: Thirty-one patients with Chikungunya fever and musculoskeletal symptoms lasting more than three months, recruited from the Rheumatology outpatient clinic at Clinical Hospital, Federal University of Pernambuco (HC-UFPE). METHODS: Patients (aged 56±10 years) were randomly assigned into one of two groups: Resistance Exercise Group (REG, N.=15) or Control Group (CG, N.=16). REG performed progressive resistance exercises with elastic bands (24 sessions over 12 weeks). CG only had their symptoms monitored through phone calls, maintaining the usual care treatment. Assessments were taken at baseline and after 6 and 12 weeks of the following: physical function (30-second Chair Stand Test (30-s CST), 4-step Stair Climb Power Test (4SCPT), 40-m Fast-paced Walk Test (40m FPWT), and Disabilities of the Arm, Shoulder, Hand (DASH) questionnaire); pain (VAS and painful joints count); quality of life (Medical Outcomes Study 36-Item Short-Form Health Survey [SF-36]); and Patient Global Impression of Change (PGIC) scale. RESULTS: There was a reduction of pain (P=0.01; d=-0.83) and an improvement of 30-s CST (P=0.04; d=0.85) in REG participants after 12 weeks. There was no significant change in the domains of SF-36. Nearly 70% of trained patients reported improvement on PGIC. CONCLUSIONS: Resistance exercises improved physical function in sitting and standing and reduced pain in patients with chronic Chikungunya fever. CLINICAL REHABILITATION IMPACT: Resistance exercises can be considered as a treatment approach for patients with musculoskeletal disorders in the chronic stage of Chikungunya fever.

Efficacy of Manual Therapy on Pain, Impact of Disease, and Quality of Life in the Treatment of Fibromyalgia: A Systematic Review.

BACKGROUND: Myofascial mobilization has been used as an intervention for patients with fibromyalgia (FM) for acting on ascending nociceptive pathways possibly involved in the central sensitization process, modulating the pain experience. However, there is still a gap in its efficacy compared with another hands-on approach because manual therapy has nonspecific effects, such as placebo. OBJECTIVES: This systematic review aims to review the scientific literature for an overview of the efficacy of manual therapy in pain, disease impact, and quality of life in patients with FM compared with control or other treatments through randomized clinical trials. STUDY DESIGN: This study involved systematic review of published randomized controlled trials (RCTs). SETTING: This study examined all RCTs evaluating the effect of manual therapy on pain, impact of disease, and quality of life for patients with FM. METHODS: Systematic review. The research was performed in 9 databases: MEDLINE/PubMed, CINAHL, Web of Science, Scopus, ScienceDirect, Lilacs, SciELO, PEDro, and Cochrane. Searches were carried out from the end of the project until September 2019, with no language and year restrictions. Randomized controlled clinical trials that used the following outcome measures were included: Visual Analog Scale, Fibromyalgia Impact Questionnaire, and SF-36 Quality of Life Questionnaire. The risk of bias and quality of studies was assessed using the PEDro scale; the Cochrane risk-of-bias tool; and Grading of Recommendations Assessment, Development, and Evaluation System. RESULTS: Seven studies were included (368 patients). The quantitative analysis was performed on 4 studies because of the lack of data in the others. Myofascial release was the most used modality. The level of evidence ranged from very low to moderate, mainly because of the inconsistency and inaccuracy of results. LIMITATIONS: The present systematic review presented limitations because of the heterogeneity of the included studies and only a short-term analysis of the intervention results. It was observed that other information, such as pressure, repetition, and/or sustaining manual therapy techniques, could be better described in future protocols, aiming at a better comparison between the techniques and their subsequent reproducibility. CONCLUSIONS: Current evidence of manual therapy in patients with FM, based on a very low to moderate quality of evidence, was inconclusive and insufficient to support and recommend the use of manual therapy in this population. To date, only general osteopathic treatment has achieved clinically relevant pain improvement when compared with control.
