Enfermedad musculoesquelética en población trabajadora: perfil de los afectados y manejo farmacológico / Musculoesqueletic diseases in working population: subjects' profile and pharmacological management

El presente estudio describe las enfermedades musculoesqueléticas (EME) de una cohorte de trabajadores de tipo manual, así como el uso de los fármacos indicados para el control del dolor. Estudio observacional retrospectivo llevado a cabo en el ámbito del Aragon Workers' Health Study (AWHS). Se ha analizado la prevalencia de las diferentes EME, la tasa de utilización de fármacos empleados en el tratamiento del dolor y el número de dosis diarias definidas (DDD) consumidas. El 15,4% de los trabajadores estudiados fueron diagnosticados de, al menos, una EME. De ellos, el 54,1% tenía sobrepeso y el 74,0% eran mayores de 55 años. La tasa de utilización de los antiinflamatorios no esteroideos (AINE) fue del 69,5%, y de los analgésicos no opiáceos, del 29,9%. Los datos presentados ponen de manifiesto la utilización elevada y, en algunos casos, continuada que existe de tratamientos analgésicos y antiinflamatorios. (AU)

The present study describes the musculoskeletal diseases (MSD) of a cohort of manual workers, as well as the use of drugs indicated for pain control. Retrospective observational study carried out within the framework of the Aragon Workers' Health Study (AWHS). The prevalence of the different EMEs, the rate of use of drugs used in the treatment of pain and the number of defined daily doses (DDD) consumed have been analysed. 15.4% of the workers studied were diagnosed with at least one EME. Of them, 54.1% were overweight and 74.0% were older than 55 years. The utilization rate of non-steroidal anti-inflammatory drugs (NSAIDs) was 69.5%, and of non-opioid analgesics, 29.9%. The data presented show the high use and, in some cases, the continuous use of analgesic and anti-inflammatory treatments. (AU)

Relationship between knee alignment in asymptomatic subjects and flexibility of the main muscles that are functionally related to the knee.

Objective To assess the relationship between static frontal knee alignment in asymptomatic subjects and flexibility of the main muscles functionally related to the knee. Methods A descriptive cross-sectional study was performed in 33 healthy adults (19-31 years). The frontal knee angle (valgus/varus angle) was measured by photogrammetry and it was measured in the lateral side. Therefore, high values were assigned for genu varum and low values for genu valgum. Iliopsoas, gluteus maximus and medius, rectus femoris, biceps femoris, vastus of the quadriceps, and gastrocnemius muscles were stretched. Muscles were classified as normal, reflex hypomobile, or structural hypomobile. Results Women had significantly greater valgus than did men (right angle, women: 174.41°/men: 177.41°; left angle, women: 174.20°/men: 178.70°). The right frontal plane knee angle was higher in women with structural hypomobile vastus. The left frontal plane knee angle was higher in women with structural hypomobile iliopsoas. No relationships were found in men. Conclusions A tighter vastus of the quadriceps and tighter iliopsoas are related to greater genu varum in adult women. Stretching the vastus of the quadriceps and iliopsoas when there is a tendency for excess varus in the knee, to prevent overuse injury or early osteoarthritis, might be clinically relevant.

Contribution of Dry Needling to Individualized Physical Therapy Treatment of Shoulder Pain: A Randomized Clinical Trial.

Study Design Multicenter, parallel randomized clinical trial. Background Myofascial trigger points (MTrPs) are implicated in shoulder pain and functional limitations. An intervention intended to treat MTrPs is dry needling. Objectives To investigate the effectiveness of dry needling in addition to evidence-based personalized physical therapy treatment in the treatment of shoulder pain. Methods One hundred twenty patients with nonspecific shoulder pain were randomly allocated into 2 parallel groups: (1) personalized, evidencebased physical therapy treatment; and (2) trigger point dry needling in addition to personalized, evidence-based physical therapy treatment. Patients were assessed at baseline, posttreatment, and 3-month follow-up. The primary outcome measure was pain assessed by a visual analog scale at 3 months, and secondary variables were joint range-of-motion limitations, Constant-Murley score for pain and function, and number of active MTrPs. Clinical efficacy was assessed using intention-to-treat analysis. Results Of the 120 enrolled patients, 63 were randomly assigned to the control group and 57 to the intervention group. There were no significant differences in outcome between the 2 treatment groups. Both groups showed improvement over time. Conclusion Dry needling did not offer benefits in addition to personalized, evidencebased physical therapy treatment for patients with nonspecific shoulder pain. Level of Evidence Therapy, level 1b.

Contributions of myofascial pain in diagnosis and treatment of shoulder pain. A randomized control trial.

BACKGROUND: Rotator cuff tendinopathy and subacromial impingement syndrome present complex patomechanical situations, frequent difficulties in clinical diagnosis and lack of effectiveness in treatment. Based on clinical experience, we have therefore considered the existence of another pathological entity as the possible origin of pain and dysfunction. The hypothesis of this study is to relate subacromial impingement syndrome (SIS) with myofascial pain syndrome (MPS), since myofascial trigger points (MTrPs) cause pain, functional limitation, lack of coordination and alterations in quality of movement, even prior to a tendinopathy. MTrPs can coexist with any degenerative subacromial condition. If they are not taken into consideration, they could perpetuate and aggravate the problem, hindering diagnosis and making the applied treatments ineffective.The aims and methods of this study are related with providing evidence of the relationship that may exist between this condition and MPS in the diagnosis and treatment of rotator cuff tendonitis and/or SIS. METHOD/DESIGN: A descriptive transversal study will be made to find the correlation between the diagnosis of SIS and rotator cuff tendonitis, positive provocation test responses, the existence of active MTrPs and the results obtained with ultrasonography (US) and Magnetic Renonance Imaging (MRI). A randomized double blinded clinical trial will be carried out in experimental conditions: A Protocolized treatment based on active and passive joint repositioning, stabilization exercises, stretching of the periarticular shoulder muscles and postural reeducation. B. The previously described protocolized treatment, with the addition of dry needling applied to active MTrPs with the purpose of isolating the efficacy of dry needling in treatment. DISCUSSION: This study aims to provide a new vision of shoulder pain, from the perspective of MPS. This syndrome can, by itself, account for shoulder pain and dysfunction, although it can coexist with real conditions involving the tendons. TRIAL REGISTRATION: ISRCTN Number: 30907460.
