In people with shoulder pain, what is the effect of adding mobilisation with movement (MWM) to a standard exercise program on function and pain compared with sham MWM and the same exercise program? A randomised trial with concealed allocation, blinded outcome assessment and intention-to-treat analysis. Seventy people with chronic atraumatic rotator cuff related pain, with a mean age 48 years (SD 10). The experimental group received MWM plus exercise and the control group received sham MWM plus exercise. Treatments were delivered twice per week for 5 weeks. The primary outcome measures were function (0 to 100 Shoulder Pain and Disability Index) and pain (0 to 10 Numerical Pain Rating Scale). Secondary outcomes were self-efficacy, perceived improvement and active pain-free range of movement. Assessment time points were at baseline (week 0), the end of the treatment period (week 5) and a follow-up 1 month after the end of treatment (week 9). At week 5, the experimental group improved more than the control group in function (MD –15 points, 95% CI –24 to –7), pain at night (MD –2.1, 95% CI –3.1 to –1.1), pain on movement (MD –1.5, 95% CI –2.5 to –0.6) and active range of movement in flexion (MD 16 deg, 95% CI 1 to 30), abduction (MD 23 deg, 95% CI 6 to 40), external rotation (MD 11 deg, 95% CI 4 to 17) and hand behind back (MD 20 deg, 95% CI 8 to 32). At week 9, benefits were seen in the Shoulder Pain and Disability Index (MD –9 points, 95% CI –17 to –1), pain at night (MD –1.9, 95% CI –2.9 to –0.8) and on movement (MD –1.3, 95% CI–2.3 to –0.3). The effects of the experimental intervention on other outcomes were mostly unclear due to wide confidence intervals. Blinding was successful. Adding MWM to exercise improved function, pain and active range of movement in people with shoulder pain. These benefits were not placebo effects. NCT04175184. [ABSTRACT FROM AUTHOR]

This study aimed to identify the knowledge about the different characteristics of and the use of extrinsic feedback (EF) by Brazilian physical therapists. This is a cross-sectional study, and we used an internet-based survey with questions about knowledge and application of extrinsic feedback in clinical practice. We analyzed the responses in relation to the best available evidence on motor control and learning. We recruited Brazilian registered physical therapists from different regions in Brazil. Participants' demographics and survey responses were analyzed using descriptive statistics. Two hundred and forty-six Brazilian physical therapists participated in the study. Most participants affirmed not knowing the definition of EF (55.69%), confirmed using some form of EF in their clinical practice (86.59%), and reported using it in 50% to 90% of their patients (26.42%). Brazilian physical therapists reported using mainly summary feedback (69.10%) with external focus of attention (63.41%). Participants reported using concurrent feedback (82.83%) and delivered it after every exercise repetition (63.82%). Most participants (43.09%) did not assess learning retention. Answers were similar regardless of education level or time from graduation. The results of this survey suggest that Brazilian physical therapists do not have sufficient knowledge about the different characteristics of EF; however, they do consider EF useful and use it for most of their patients. Brazilian physical therapists adopted adequate content characteristics of EF but not adequate use of timing characteristics of EF. [ABSTRACT FROM AUTHOR]

Objectives. To study the correlation between avascular necrosis and the demographics, time elapsed from fracture to surgery, quality of reduction, Garden classification, and the position of the screw following use of the dynamic hip screw (DHS) in the treatment of subcapital neck fractures. Methods. A prospective study of 96 patients with subcapital neck fractures was carried out in a faculty hospital. Patients underwent surgery with closed reduction and internal fixation with DHS. Results. There were 58% male and 42% female patients, with a mean age of 53 years (+/-14). In terms of Garden classification, 60% were Garden IV, 26% were Garden III, and 14% were Garden II. Nonunion was observed in three cases (3%) and was treated with valgus intertrochanteric osteotomy, in all cases leading to successful healing. Avascular necrosis was observed in 16% of patients. The positioning of the screw into the femoral head showed a significant correlation with necrosis. Conclusions. The incidence of necrosis in patients under the age of 50 years is twice as high as that in older patients. Displacement is a predictive factor regarding osteonecrosis and is associated with a high and anterior position of the screw in the femoral head. Level II of evidence. Study Type: therapeutic study.

• Back-PAQ-Br is a questionnaire that evaluates attitudes and beliefs about back pain • Back-PAQ-Br has measurement properties that are similar to the original version • Back-PAQ-Br is reliable and valid to assess attitudes and beliefs about back pain • Back-PAQ-Br can assess people with and without back pain, and healthcare professionals • Back-PAQ-Br can be used in research and in the clinical setting The Back Pain Attitudes Questionnaire (Back-PAQ) was developed to evaluate attitudes and beliefs of the general public, people with back pain, and healthcare professionals about the spine. To translate and cross-culturally adapt the Back-PAQ (34-item and 10-item versions) into Brazilian-Portuguese (Back-PAQ-Br) and test its measurement properties in a Brazilian sample. The cross-cultural adaptation and testing of the measurement properties followed the recommendations of international guidelines. Members of the general public, people with back pain, and healthcare professionals, for a total of 139 individuals, took part in the assessment of internal consistency, construct validity, and ceiling and floor effects. The Hospital Anxiety and Depression Scale (HADS) and the Brazilian-Portuguese version of the Tampa Scale of Kinesiophobia (TSK) were used to evaluate construct validity. Test-retest reproducibility was determined on 77 participants. Retest was performed a minimum of 1 week and a maximum of 2 weeks from the original test. There was very high agreement between translators (88.2%). The Back-PAQ-Br showed excellent internal consistency (Cronbach's alpha 0.92) and excellent reproducibility (ICC 0.94; SEM 5.14 points on a 136 point scale), with a smallest detectable change (90% confidence level) of 11.93 points. There was strong correlation between Back-PAQ-Br and TSK (r = -0.72) and very weak correlation between Back-PAQ-Br and HADS (r = -0.23 for both depression and anxiety domains). No ceiling/floor effects were observed. The translation process and cross-cultural adaptation had very high agreement between translators. The Back-PAQ-Br has excellent measurement properties that are similar to the properties of the original version. [ABSTRACT FROM AUTHOR]
