Background: The Standardised Nordic Questionnaire (SNQ) is an instrument to analyse the musculoskeletal symptoms in an ergonomic or occupational health context. We aimed to cross-culturally adapt and evaluate the psychometric properties of the SNQ among Spanish musicians. Methods: Cross-cultural adaptation and psychometric validation (reliability, validity, and feasibility) was performed. Reliability was analysed by test-retest reliability (Cohen’s Kappa) and internal consistency (Kuder–Richardson). Content and face validity were measured by the Expert Committee and the opinion of participants. Construct validity (Mann–Whitney U test) was measured by comparing with questionnaires used to assess pain and disability in neck, shoulders, upper back, and low back regions. Feasibility was calculated with the average response time. Results: A total of 312 Spanish musicians were included. The Spanish version of SNQ achieved good semantic, conceptual, idiomatic, and content equivalence. For most of the variables, test-retest reliability was good to very good (k = 0.60–0.81). The internal consistency showed good to acceptable (Kuder–Richardson 20 (KR20) = 0.737–0.873). Participants with versus without musculoskeletal problems in a related region showed significantly higher disability/pain, indicating a good construct validity. About the feasibility, the average response time of the questionnaire was 6 min (±2). Conclusions: The results show that the Spanish SNQ is reliable, valid, and feasible screening tool to assess musculoskeletal problems among musicians.

Background: Playing-related musculoskeletal disorders are the most frequent complaints among instrumental musicians. The aims of this study were: to assess the prevalence of musculoskeletal pain; to evaluate neck, shoulder, and lower back disability; and to determine the associated factors with the presence of musculoskeletal pain among musicians. Methods: A population-based, cross-sectional descriptive study was conducted. We selected Spaniard musicians over 16 years old who played a musical instrument for at least five hours per week. They answered the Spanish versions of the Standardised Nordic Questionnaire, the Oswestry Disability Index, Neck Disability Index and Shoulder Pain and Disability Index. Results: We found 94.8% of musicians presented at least one symptomatic region in the last 12 months, and 72.3% in the last seven days. Female musicians (OR 4.38, CI 2.11−9.12), musicians with overweight or obesity (OR 5.32, CI 2.18−12.97), and musicians who play more than 14 h per week (OR 3.86, CI 1.80−8.29)were shown to be a higher risk of suffering musculoskeletal pain. Conclusions: Musculoskeletal disorders symptoms are highly prevalent in musicians. The main risk factors related to musculoskeletal disorders symptoms were gender (being female), overweight, obesity, and spending playing more than 14 h a week practicing. This study highlights the need to provide strategies to prevent occupational disabilities among musicians. Further studies are needed to analyse the prevalence of pain in the musician using other sampling methods.

Neck pain is a frequent health problem. Manual therapy (MT) and transcutaneous electrical nerve stimulation (TENS) are recommended techniques for treatment of mechanical neck disorders (MND) in Spanish Public Primary Care Physiotherapy Services. The aim of this study was to compare the efficacy of MT versus TENS in active mobility and endurance in cervical subacute or chronic neck pain. Ninety patients with MND were randomly allocated to receive ten 30-min sessions of either MT or TENS, in a multi-centered study through 12 Primary Care Physiotherapy Units in the Madrid community. Active cervical range of motion (CD-ROM) and endurance (Palmer and Epler test) were evaluated pre- and post-intervention and at 6-month follow-up. A generalized linear model of repeated measures was constructed for the analysis of differences. Post-intervention MT yielded a significant improvement in active mobility and endurance in patients with subacute or chronic MND, and at 6-month follow-up the differences were only significant in endurance and in sagittal plane active mobility. In the TENS group, no significant improvement was detected. With regard to other variables, MT improved mobility and endurance more effectively than TENS at post-intervention and at 6-month follow-up in the sagittal plane. Only MT generated significant improvements in cervical mobility and endurance in the three movement planes.

There is an increasing incidence, prevalence, and burden of knee osteoarthritis due to a global increase in obesity and an aging population. The aim of the present study was to compare the effectiveness of the addition of aerobic exercises performed in an unloaded or loaded position to a conventional exercise program in overweight subjects with knee osteoarthritis. Twenty-four subjects were randomly allocated to receive 36 sessions of 30-min duration of either sitting aerobic exercises (experimental group) or standing aerobic exercises (control group). Pain intensity, knee disability, and quality-of-life data were collected at baseline and at 12, 24, and 36 sessions. Generalized linear mixed models (GLMMs) were constructed for the analysis of the differences. Significant differences were found in the experimental group for self-reported pain and knee pain and disability at 24 and 36 sessions (p < 0.05). Significant between-group differences were observed in change in self-reported knee pain and disability and quality of life from baseline to 24th- and 36th-session measurements in favor of the experimental group. Adherence to treatment was higher in the experimental group. Adding aerobic exercises in an unloaded position to a conventional exercise program produced superior effects over time for self-reported knee pain, knee pain and disability and quality of life compared to loaded aerobic exercises in overweight subjects with knee osteoarthritis.

There is a great concern whether Physical Therapy students upon completion of their educational program are ready and equipped with the requisite skills to construct and implement a successful patient intervention with culturally diverse groups. The purpose of this study is to describe the professional and personal physical therapist development of Physical Therapy students after participating in Solidarity Activities in Collaboration with a Prisoner reinsertion program as a service-learning course. A qualitative approach was used. A convenience sample of twenty physical therapy students doing service learning and one teaching professor were included. Student diaries were analyzed. Semi-structured interviews were done to explore five students’ and the professor’s judgements. Internal and external observations and filling out structure field-notes were also used as data triangulation in order to build the conceptual model. The main findings include that the application of knowledge and practice of skills in different environments are the most important skills attained with this service learning. Five key themes emerged from the data analysis, namely: application of knowledge, adaptation to different environments, improving communication with patients, assisting people and providing treatment with self-confidence. A recommendation is that Physical Therapy programs include workplace practice in different environments to enhance the development of professionalism among students.

The aim has been to translate and cross-culturally adapt the Exercise Adherence Rating Scale (EARS) for Mexican Spanish speaking population with non-specific chronic low back pain and assess its psychometric properties. The study had two phases: translation and cultural adaptation, followed by psychometric validation. Reliability was assessed with internal consistency (Cronbach's alpha) and test-retest reliability (intraclass correlation coefficient); validity with construct validity (Spearman's correlation) and factor analysis; sensitivity to change with effect size and standardized response mean difference; feasibility by completion time in seconds; and ceiling/floor effects were calculated. A total of 161 subjects were included. Cronbach's alpha (0.93; 95% CI 0.92-0.95) indicated good internal consistency, and intraclass correlation (0.95; 95% CI: 0.89-0.97) showed excellent test-retest reliability. Weak correlations between the EARS vs. the Visual Analogue Pain Rating Scale and the Roland Morris Disability Questionnaire were found (r = -0.29 and r = 0.00 respectively). All effect size values indicated that the scale presented a significant sensitivity to change. The average time to complete the EARS-Mx was 219 s. No ceiling or floor effect was detected. The EARS-Mx showed semantic, conceptual, idiomatic, content and operational equivalence with respect to the original scale, and appropriate metric properties of reliability, validity, sensitivity to change and feasibility.
