Purpose: This systematic review and meta-analysis identifies, critically appraises, synthesizes, and meta-analyses the reported psychometric properties of the Patient-Specific Functional Scale (PSFS) in patients with low back pain or pathology. Method: The MEDLINE, Embase, PubMed, and Google Scholar databases were searched from their inception to September 2019. We included prospective measurement studies that reported on the psychometric properties (reliability, validity, responsiveness) of the PSFS in people with low back pain or pathology. We followed the COnsensus-based Standards for the selection of health Measurement INstruments 2018 guideline for systematic reviews. We performed both quantitative and qualitative syntheses in which the results were summarized on the basis of the reported measurement properties and study quality. Results: Ten eligible studies were included. The pooled PSFS reliability measure was excellent (intra-class correlation coefficient = 0.89; 95% CI: 0.75, 0.95). Validity measures displayed correlations that ranged from −0.47 to 0.69 when compared with other patient-reported outcome measures (PROMs) or other tests. Eight studies had assessed the responsiveness of the PSFS. Effect sizes reported were large (≥ 0.91). Conclusions: The PSFS is a reliable, valid, and responsive PROM for patients with low back pain or pathology.

Background: The goal of treatment for a proximal hamstring avulsion (PHA) is an objectively restored muscle and a subjectively satisfied, pain-free patient at follow-up. Different self-reported and performance-based outcome measures have been used to evaluate recovery, but their validity is poorly investigated. Purpose: To investigate 1) the correlation between the commonly used self-reported outcome measurements, the Perth Hamstring Assessment Tool (PHAT) and the Lower Extremity Functional Scale (LEFS); 2) to what extent these scores can be explained by physical dysfunction as measured by performance-based tests; 3) whether performance-based tests can discriminate between the injured and uninjured extremity; and 4) which activity limitations are perceived by patients several years after the injury. Study design: Cohort study (Diagnosis); Level of evidence, 3. Methods: We included a consecutive series of patients treated for or diagnosed with PHA in our department between 2007 and 2016 having at least 2 tendons avulsed from the ischial tuberosity. Participants attended 2 study visits, answered questionnaires (PHAT, LEFS, and Patient-Specific Functional Scale [PSFS]), and performed physical performance–based tests (single-leg hop tests, single–step down test, and isometric and isokinetic strength tests). Results: A total of 50 patients were included (26 men [52%], 24 women [48%]; mean age, 50.9 years [SD, 9.8 years]). The mean follow-up time was 5.5 years (SD, 2.7 years), and 74% had been surgically treated. The correlation between PHAT and LEFS was strong ( r = 0.832) and statistically significant ( P < .001). Seven of the performance-based tests exhibited a statistically significant but weak correlation with LEFS (0.340-0.488) and 3 of the tests to PHAT (–0.304 to 0.406). However, only peak torque could significantly discriminate between the extremities. The activity limitation most commonly mentioned in PSFS was running (16 patients [32%]). Conclusion: Although PHAT and LEFS correlated strongly, the correlations between functional tests and the patient-reported outcome scores were weak, and most functional tests failed to discriminate between the injured and uninjured lower extremity in patients with PHA 5 years after injury. In general, patients alleged few activity limitations, but running difficulty was a common sequela after PHA.

Abstract Background and Purpose. Symphysis pubis pain is a significant problem for some pregnant women. The purpose of this study was to investigate the effects of exercise, advice, and pelvic support belts on the management of symphysis pubis dysfunction during pregnancy. Subjects. Ninety pregnant women with symphysis pubis dysfunction were randomly assigned to 3 treatment groups. Methods. A randomized masked prospective experimental clinical trial was conducted. Specific muscle strengthening exercises and advice concerning appropriate methods for performing activities of daily living were given to the 3 groups, and 2 of the groups were given either a rigid pelvic support belt or a nonrigid pelvic support belt. The dependent variables, which were measured before and after the intervention, were a Roland-Morris Questionnaire score, a Patient-Specific Functional Scale score, and a pain score (101-point numerical rating score). Results. After the intervention, there was a significant reduction in the Roland-Morris Questionnaire score, the Patient-Specific Functional Scale score, and the average and worst pain scores in all groups. With the exception of average pain, there were no significant differences between groups for the other measures. Discussion and Conclusion. The findings indicate that the use of either a rigid or a nonrigid pelvic support belt did not add to the effects provided by exercise and advice.

BackgroundThe evidence that exercise intervention is effective for treatment of chronic low back pain comes from trials that are not placebo-controlled.ObjectiveThe purpose of this study was to investigate the efficacy of motor control exercise for people with chronic low back pain.DesignThis was a randomized, placebo-controlled trial.SettingThe study was conducted in an outpatient physical therapy department in Australia.PatientsThe participants were 154 patients with chronic low back pain of more than 12 weeks’ duration.InterventionTwelve sessions of motor control exercise (ie, exercises designed to improve function of specific muscles of the low back region and the control of posture and movement) or placebo (ie, detuned ultrasound therapy and detuned short-wave therapy) were conducted over 8 weeks.MeasurementsPrimary outcomes were pain intensity, activity (measured by the Patient-Specific Functional Scale), and patient's global impression of recovery measured at 2 months. Secondary outcomes were pain; activity (measured by the Patient-Specific Functional Scale); patient's global impression of recovery measured at 6 and 12 months; activity limitation (measured by the Roland-Morris Disability Questionnaire) at 2, 6, and 12 months; and risk of persistent or recurrent pain at 12 months.ResultsThe exercise intervention improved activity and patient's global impression of recovery but did not clearly reduce pain at 2 months. The mean effect of exercise on activity (measured by the Patient-Specific Functional Scale) was 1.1 points (95% confidence interval [CI]=0.3 to 1.8), the mean effect on global impression of recovery was 1.5 points (95% CI=0.4 to 2.5), and the mean effect on pain was 0.9 points (95% CI=−0.01 to 1.8), all measured on 11-point scales. Secondary outcomes also favored motor control exercise.LimitationClinicians could not be blinded to the intervention they provided.ConclusionsMotor control exercise produced short-term improvements in global impression of recovery and activity, but not pain, for people with chronic low back pain. Most of the effects observed in the short term were maintained at the 6- and 12-month follow-ups.

To categorize the Patient-specific Functional Scale (PSFS) activities in snakebite envenoming (SBE) using the International Classification of Function (ICF) model in order to describe the impact of SBE on patients’ activities and daily lives and to develop a theoretical SBE model of functioning, we performed a post-hoc analysis of two multi-center, prospective studies, conducted at 14 clinical sites in the United States with consecutive SBE patients presenting to the emergency department. Qualitative content analysis and natural language processing were used to categorize activities reported in the PSFS using the ICF model. Our sample included 93 patients. The mean age was 43.0 (SD 17.9) years, most had lower extremity injuries (59%). A total of 99 unique activities representing eight domains came within the Activity and Participation component of the ICF model, with the majority in the Mobility and General Tasks and Demands domains. The main concerns of SBE patients are the ability to perform daily activities and to engage within their social environment. Applying the ICF model to SBE can facilitate the creation of a patient-centered treatment approach, moving beyond body-structural impairments towards a function-based treatment approach and facilitate early integration of rehabilitation services.

Lesões podem gerar consequências funcionais e mudanças de vida para o indivíduo. Além do exame físico, a aplicação de questionários de autorrelato são fundamentais para a tomada de decisão, determinação do prognóstico e avaliação da eficácia do tratamento. O Patient Specific Functional Scale (PSFS) é um questionário individual que avalia o estado funcional do indivíduo.  Suas vantagens propostas incluem sua ampla aplicabilidade, facilidade de administração, e adequada responsividade para análise da evolução funcional. Entretanto, esta escala ainda não está disponível na versão em português-brasileiro. Objetivo: Realizar a tradução e adaptação transcultural do questionário e analisar sua validade, confiabilidade e responsividade em pacientes com lesões do membro superior. Métodos: O PSFS-Br foi desenvolvido usando diretrizes padronizadas e o processo de tradução ocorreu em 5 etapas. Após a versão definitiva, 100 pacientes com lesões do membro superior foram recrutados e responderam o PSFS-Br, Quick-DASH-Br a Escala Visual Analógica em três ocasiões. Resultados: A compreensão adequada do instrumento pela população alvo resultou em boa validade de face. O PSFS-Br, quando comparado ao QuickDASH-Br, apresentou validade de construto fraca r = -0,36, excelente confiabilidade teste-reteste (ICC = 0,91) e apresentou alta responsividade com Tamanho do Efeito(TE) = 1,85, Média da resposta Padronizada (MRP) = 2, 75, Erro padrão de medida (EPM) = 0,36 e Minima diferença dectável (MDD) = 1,5. Conclusão: Este estudo demostrou que o PSFS-Br é uma ferramenta válida, confiável e responsiva para pacientes brasileiros com lesões do membro superior.
