Background: Exercise buddies (people to exercise together with) might support people with low back pain (LBP) to become active. However, involving buddies in randomised controlled trials (RCT) might challenge recruitment, data collection and follow-up.

Objectives: To explore the feasibility of the intervention, recruitment and data collection approaches and potential effects of a health coaching intervention (focused on physical activity) with or without exercise buddies' support on physical activity of people with chronic LBP versus usual discharge care.

Purpose: To determine: (1) the smallest change in function patients would need to see following a self-management intervention for low back pain (LBP) to consider it worthwhile; (2) the association between patient-related factors and the magnitude of the smallest worthwhile change.

Methods: A cross-sectional analysis of 212 participants of the TEXT4myBACK randomised trial was conducted. At baseline, participants nominated the smallest change in function (0-30 scale) following a self-management program they would need to reach to consider it worthwhile.

Objective: To investigate the usefulness and performance metrics of three freely-available softwares (Rayyan®, Abstrackr® and Colandr®) for title screening in systematic reviews.

Study Design And Setting: In this methodological study, the usefulness of softwares to screen titles in systematic reviews was investigated by the comparison between the number of titles identified by software-assisted screening and those by manual screening using a previously published systematic review. To test the performance metrics, sensitivity, specificity, false negative rate, proportion missed, workload and timing savings were calculated.

Background: The International Hip Outcome Tool (iHOT-33) is a reference instrument among the Patient-Reported Outcome Measures (PROMs) to assess people with hip disorders, including femoroacetabular impingement (FAI) syndrome. Older questionnaires such as the Harris Hip Score, or its modified version (mHHS), and the Hip Outcome Score (HOS), through the full version or its subscales (Activities of Daily Living-ADL; and Sports) are still used in the clinical setting and their construct validity is so far underexplored.

Objective: To assess the construct validity of mHHS and HOS-ADL compared with iHOT-33 by hypothesis testing in a large sample of patients with FAI syndrome.

Background/objective: We aimed to investigate the yearly online public interest for gout, low back pain, neck pain, osteoarthritis, and rheumatoid arthritis, the most popular topics searched for these conditions, and the association between the change in their interest over time and the sociodemographic index of the search location.

Methods: We conducted online searches in Google Trends for the aforementioned conditions between 2004 and 2020. The search volumes for each condition (relative to all searches conducted in the period) and the top and rising related queries and topics were downloaded and summarized.

Objective: To describe the measurement of adherence to unsupervised, conservative treatments for knee osteoarthritis (OA), including the methods of adherence measurement, parameters for assessing adherence and any values used to quantify adherence.

Methods: A systematic review with search terms related to knee OA, conservative treatments and adherence was conducted. The protocol was registered with the International Prospective Register of Systematic Reviews (registration number CRD42020158188).

Objective: The authors sought to describe the protocol of a randomized controlled trial that will investigate the effects of the TEXT4myBACK self-management text message intervention compared with control in people with low back pain (LBP).

Methods: A single-blind (assessor and statistician), randomized controlled trial with economic analysis and process evaluation will be conducted. A total of 304 people with non-specific LBP of less than 12 weeks will be enrolled and randomly allocated either to TEXT4myBACK intervention or control groups.

Introduction: The benefits of family-based interventions for patients with musculoskeletal pain have been previously shown in individual randomized controlled trials (RCTs), but no systematic review has summarized their effects.

Materials And Methods: A systematic review was conducted to assess the effectiveness of family-based interventions on clinical and biopsychosocial outcomes in people with musculoskeletal pain (PROSPERO CRD42018118442). Meta-analyses were performed for the outcomes of pain intensity, disability, mood, self-efficacy, and marital adjustment.

This study investigated the effects of concurrent training performed either with repetitions to failure or not to failure in muscle power, muscle quality (MQ), peak oxygen uptake (VO), and visceral fat in older men. This is an ancillary analysis of a randomized controlled trial. 36 older men (mean age ± SD; 67.

Purpose: To examine the differences between performing Nordic hamstring exercises once or twice a week on hamstring eccentric strength and other muscle-strain risk factors in high-level football players.

Methods: In this randomized trial, 32 football players (18-23 y old) completed an 8-week Nordic hamstring exercise training program in 1 of 2 experimental groups: group 1 (once a week; n = 15) and group 2 (twice a week; n = 17). Knee-flexor/extensor peak torques and biceps femoris long-head muscle architecture were assessed through isokinetic dynamometry and ultrasonography, respectively, before and after the training programs.

This study aimed to evaluate the influence of hamstrings and quadriceps strength on the hamstrings-to-quadriceps conventional (H:Q) and functional (H:Q) ratios in male soccer players. Quadriceps concentric peak torque (PT) and hamstrings concentric and eccentric PT were assessed with isokinetic dynamometry at 60°/s in 101 players (202 legs). The cut-points of 0.

Article Synopsis
  • - The study investigates intrinsic risk factors associated with hamstring strain injuries (HSI) in professional and under-20 football players, revealing that 30% of participants had previously sustained at least one HSI.
  • - Professional players showed a higher prevalence of HSI history (40%) compared to under-20 players (18%), but no significant differences were found in other screening measures.
  • - Most players exhibited multiple risk factors for HSI, with hamstring weakness being the most common, and a significant percentage had issues with flexibility, functional movements, and strength imbalances.

Muscle fatigue is a potential risk factor for hamstring strain injuries in soccer players. The aim of this study was to verify the effect of photobiomodulation therapy (PBMT) on the hamstrings' muscle fatigue of soccer players during a simulated match. Twelve male amateur soccer players (~ 25 years) participated in this randomized, crossover, double-blinded, placebo-controlled trial.

Purpose: The purpose of this study was to investigate the effects of photobiomodulation therapy (PBMT) combined with resistance training on knee extensors muscle mass, strength and functional capacity in elderly men.

Methods: In this randomized double-blinded placebo-controlled trial, healthy elderly men (age 60-80 years) completed 12 weeks of resistance training (2×/week) with application of placebo (n = 13) or active PBMT (n = 11) on quadriceps muscles (850 nm, 240 J per limb) before each training session. Leg press and knee extension one-repetition maximum (1RM) tests, isometric and concentric peak torques, rectus femoris (RF) and vastus lateralis (VL) muscle thickness, timed up-and-go (TUG) and chair rise-to-standing (CRS) tests were performed before and after the intervention period.

Promising effects of phototherapy on markers of exercise-induced muscle damage has been already demonstrated in constant load or isokinetic protocols. However, its effects on more functional situations, such as plyometric exercises, and when is the best moment to apply this treatment (pre- or post-exercise) remain unclear. Therefore, the purpose of this study was to investigate the effect of low-level laser therapy (LLLT) before or after plyometric exercise on quadriceps muscle damage markers.
