Background: Mechanisms reflect the steps or processes through which an intervention unfolds and produces change in a specified outcome variable. Mechanisms are responsible for determining "how treatments work" which has emerged as a critical question for both developing theory and enhancing treatment efficacy. Studies that evaluate "how" treatments work, not just "if" treatments work are of considerable importance.

Discussion: Specific and shared mechanisms research is a promising approach which aims to improve patient outcomes by tailoring treatments to the specific needs of each patient. Mechanisms research is an underexplored area of research requiring a unique research design.

Conclusion: Although mechanisms research is still in its infancy, prioritizing the study of the mechanisms behind manual therapy interventions can provide valuable insight into optimizing patient outcomes.

Background and purpose: In neurorehabilitation clinical practice, assessment is usually more oriented to evaluate patient's present status, than to plan interventions according to predicted outcomes. Therefore, we conducted an extensive review of current prognostic models available in the literature for recovery prediction of many functions and constructs, after stroke. We reported results in the form of a practical guide for clinicians, with the aim of promoting the culture of early clinical assessment for patient stratification, according to expected outcome. To define a roadmap for clinicians, a stepwise sequence of five actions has been developed, from collecting information of past medical history to the adoption of validated prediction tools. Furthermore, a clinically-oriented organization of available prediction tools for recovery after stroke have been proposed for motor, language, physiological and independency functions. Finally, biomarkers and online resources with prognostic value have been reviewed, to give the most updated state of the art on prediction tools after stroke.

Recommendations for clinical practice: Clinical assessment should be directed both towards the objective evaluation of the present health status, and to the prediction of expected recovery. The use of specific outcome measures with predictive value is recommended to help clinicians with the definition of sound therapeutic goals.

Background: Clinically, neck pain disorders (NPD) and non-specific low back pain (NS-LBP) are respectively the fourth and first most common conditions associated with the greatest number of years lived with disability. Remote delivery of care may benefit healthcare sustainability, reduce environmental pollution, and free up space for those requiring care non-virtual care.

Methods: A retrospective analysis was performed on 82 participants with NS-LBP and/or NPD who received exercise therapy delivered solely in the metaverse using virtually reality. The study was to determine if this was achievable, safe, had appropriate outcome measures that could be collected, and if there was any early evidence of beneficial effects.

Results: The study demonstrated that virtual reality treatment delivered via the metaverse appears to be safe (no adverse events or side effects). Data for more than 40 outcome measures were collected. Disability from NS-LBP was significantly reduced (Modified Oswestry Low Back Pain Disability Index) by 17.8% (p < 0.001) and from NPD (Neck Disability Index) by 23.2% (p = 0.02).

Conclusions: The data suggest that this method of providing exercise therapy was feasible, and safe (no adverse events reported), that complete reports were obtained from a large selection of patients, and that software acquired outcomes were obtainable over a range of time points. Further prospective research is necessary to better understand our clinical findings.

Background: The reaching-transporting task as an essential daily activity impacts balance control and falling in older women. This study investigated the different muscle strategies during the head/knee level of the functional reaching-transporting task in postmenopausal women with osteoporosis.

Methods: 24 postmenopausal volunteers were classified into two groups based on the lumbar T-score: osteoporosis (≤ -2.5, n = 12) and non-osteoporosis (> -1, n = 12). Using a custom-designed device, participants randomly performed 12 reaching-transporting tasks at the head and knee levels. Electromyography signals were collected while reaching and transporting phases with a wireless system. The peak of the root means square (PRMS) and time to PRMS (TPRMS) were measured. In addition, the isometric muscle strength and the fear of falling were assessed.

Results: The isometric muscle strength in the osteoporotic group was significantly lower than in the non-osteoporotic group (P < 0.05), except for vastus lateralis (VL). The PRMS of VL, (P = 0.010) during the reaching phase and VL (P = 0.002) and gastrocnemius lateralis (GL) (P < 0.001) during transporting phase was greater than the non-osteoporotic group. The PRMS value of the muscles was greater for reaching-transporting at the knee level than the head level; this increase was significant just for VL and biceps femoris during the transporting phase (P = 0.036 and P = 0.004, respectively).

Conclusion: Osteoporotic women have more muscle activities during the reaching-transporting task, especially at the knee level, compared to the head level. Their muscle weakness may lead to insufficient stability during the task and cause disturbance and falling, which requires further investigation.

Background: The purpose of this study was to describe the diagnostic performance of the Neuropathic Pain Subscale of McGill [NP-MPQ (SF-2)] and the Self-Administered Leeds Assessment of Neuropathic Symptoms and Signs (S-LANSS) questionnaire in differentiating people with neuropathic chronic pain post total joint arthroplasty (TJA).

Methods: This study was a survey of a cohort of individuals who had undergone primary, unilateral total knee, or hip joint arthroplasty. The questionnaires were administered by mail. The time interval from operation to the completion of the postal survey varied from 1.5 to 3.5 years post-surgery. Receiver Operating Characteristic (ROC) analysis was used to assess the overall diagnostic power and determine the optimal threshold value of the NP-MPQ (SF-2) in identification of neuropathic pain.

Results: S-LANSS identified 19 subjects (28%) as having neuropathic pain (NP), while NP-MPQ (SF-2) subscale identified 29 (43%). When using the S-LANSS as the reference standard, a Receiver Operating Characteristic (ROC) analysis for NP-MPQ (SF-2) had an area under the curve of 0.89 (95% CI: 0.82, 0.97); a cut off score of 0.91 NP-MPQ (SF-2) maximized sensitivity (89.5%) and specificity (75.0%). Correlation between the measures was moderate (r = 0.56; 95% CI: 0.40, 0.68).

Conclusion: These finding suggest some conceptual overlap but some variability in diagnosis of NP which may relate to scale-tapping into different dimensions of the pain experience, or the different scoring metrics.

Trustworthy, preprocessed sources of evidence, such as systematic reviews and clinical practice guidelines, are crucial for practicing clinicians. Confidence in estimated effects is related to how different the outcome data were between the two groups. Factors including the effect size, variability of the effect, research integrity, research methods, and selected outcome measures impact confidence in the estimated effect. The current evidence suggests that post-randomization biases cannot be ruled out with a high degree of certainty in published research, limiting the utility of preprocessed sources for clinicians. Research should be prospectively registered to improve this situation, and fidelity with prospective intent should be verified to minimize biases and strengthen confidence in estimated effects. Otherwise, discussions related to preprocessed literature, including P-values, point estimates of effect, confidence intervals, post-randomization biases, external and internal validity measures, and the confidence in estimated effects required to translate research into practice confidently, are all moot points.

Background: To translate and cross-culturally adapt into Brazilian-Portuguese, and to test the measurement properties of the following items of implementation outcome measures: Acceptability of Intervention Measure (AIM), Intervention Appropriateness Measure (IAM) and Feasibility of Intervention Measure (FIM).

Methods: This was a measurement properties study in accordance with the Consensus-based Standards for the selection of health status Measurement Instruments (COSMIN). We conducted a translation and cross-cultural adaptation of three implementation measures according to guidelines for translation and cross-cultural adaptation, then we collected information from patients who had participated in remotely delivered physical therapy treatment for musculoskeletal condition. The patients answered the translated versions of the implementation outcome measures. The measurement properties of the three implementation outcome measures were collected in a test-retest assessment, with an interval of 7 to 14 days.. The measurement properties evaluated in this study were interpretability, measured using Ceiling and Floor Effects, reliability in test-retest evaluation, measured using Cronbach's Alpha Coefficient, internal consistency, measured using Intraclass Correlation Coefficient and construct validity, measured using Pearson Correlation.

Results: We included 104 participants (76 female). The average age of the sample was 56.8 (SD 14.8) years old. The items of implementation outcome measures (AIM, IAM, and FIM) showed 66.39%, 63.11%, and 63.93% of ceiling effects. The items of implementation outcome measures showed adequate internal consistency measured using Cronbach's Alpha Coefficient (AIM: 0.89, IAM: 0.91, FIM: 0.93) and values of Standard Error of Measurement between 5 and 10%, showing good measurement error. The results of AIM and IAM was classified as moderate reliability and the FIM as substantial reliability. In a total 96 correlations, > 75% of correlations met our prior hypothesis.

Conclusion: The three Brazilian-Portuguese versions of items of implementation outcome measures had adequate internal consistency, measurement error and construct validity. The three implementation outcome measures showed moderate to substantial reliability values. The Ceiling Effect was observed in the three measures, showing maximum values ​​in more than 15% of the evaluations.

Introduction: Several factors can influence the outcome after a distal radius fracture (DRF). The aim of this study was to assess whether postoperative pulp-to-palm (PTP) distance correlated with functional outcomes after plate fixation of DRF.

Materials & methods: This is a secondary analysis of a randomized controlled trial aimed to investigate the effects of plate fixation in patients with type-C fractures. Subjects (N = 135) were divided into 2 groups based on PTP distance (equal to or higher than 0 cm) at 4 weeks postoperatively. Outcome measures were collected prospectively at 3, 6 and 12 months and included Patient-Rated Wrist Evaluation (PRWE), Quick Disabilities of the Arm Shoulder and Hand (QuickDASH) scores, wrist range of motion (ROM), Visual Analog Scale (VAS) pain scores, and hand grip strength.

Results: Overall, at 3 and 6 months patients with PTP > 0 cm had significantly worse outcomes (PRWE, QuickDASH, wrist ROM) than those with PTP =0 cm. At 12 months, QuickDASH and wrist ROM were still significantly worse. In the volar-plating subgroup, patients with PTP > 0 cm had significantly worse wrist ROM and grip strength at 3 months, but no significant differences were found in subsequent follow-ups. In the combined-plating group, patients with PTP > 0 cm had significantly worse QuickDASH, wrist ROM and grip strength at 3 months. At 6 and 12 months, wrist ROM was still significantly worse.

Conclusions: Measurement of PTP distance appears to be useful to identify patients likely to have worse outcome after plating of a DRF. This could be a tool to improve the allocation of hand rehabilitation resources.
