RESUMEN
OBJECTIVE: To investigate the reliability of a novel method to measure neck surface electromyography (SEMG), kinematics, and pain during active movements in participants with neck pain. METHODS: This test-retest study evaluated 23 participants with chronic neck pain. Each was measured twice within a single session. Three-dimensional kinematics and SEMG were recorded in 10° increments during forward and side flexion, extension, and rotation of the neck. Neck position during pain occurrence was also measured. RESULTS: Intraclass correlation coefficients were >0.80 for 96% and 100% of SEMG and kinematic data, respectively. The percentage of standard error of the measurement (SEM) values were <25% for 91% of all SEMG measures; most were <15%, and some were <10%. For ranges of motion in the primary plane, percentage of SEM values were all <6% (SEM 1°-3°). Intraclass correlation coefficients for neck position during pain occurrence were all >0.60, except for right rotation (0.48) (SEM values 2°-8°). Pain occurred approximately 59% to 75% into the total range of motion and persisted to its end. CONCLUSIONS: This methodology showed good reliability. It may be suitable for neck pain subclassification to evaluate the effects of treatment on pain, kinematics, and muscle activity during functional neck movements. The point of pain occurrence suggests increasing mechanical load on tissues may be one of the causative factors for movement-associated neck pain.

Objetivo: Evaluar los efectos de un programa intensivo de fisioterapia postoperatoria basado en ejercicios respiratorios dirigido a pacientes lobectomizados mediante toracotomía abierta. Diseño : Estudio cuasiexperimental. Emplazamiento: Hospital universitario terciario. Participantes: Doscientos ocho (208) pacientes lobectomizados mediante toracotomía abierta. Intervención: Los pacientes del grupo control (n=102) recibieron atención médica/de enfermería estándar y los pacientes del grupo experimental (n=106), además de la atención clínica estándar, se sometieron a un programa de fisioterapia diaria basada en ejercicios respiratorios hasta el momento del alta hospitalaria. Variables de resultado: Las variables de resultado estudiadas incluyeron la frecuencia de complicaciones pulmonares postoperatorias (CPP) más susceptibles de tratamiento fisioterapéutico (neumonía, atelectasias e insuficiencia respiratoria) y la duración de la estancia hospitalaria (DEH). Resultados: Las características preoperatorias y quirúrgicas de ambos grupos fueron comparables. La incidencia de CPP registrada fue de un 20,6% en el grupo control y un 6,6% en el grupo experimental (p = 0,003). La mediana y el RIC de la DEH fue de 14 y 7días, respectivamente (estimador M de Huber 14,21) en el grupo control y de 12 y 6días (estimador M de Huber 12,81) en el grupo experimental. El modelo de regresión logística creado identificó al programa de fisioterapia evaluado (p = 0,017; EXP (B) [IC 95% 0,081-0,780]) y al porcentaje del FEV1 (p = 0,042; EXP (B) [IC 95% 0,941-0,999]) como factores protectores frente al desarrollo de CPP en los pacientes intervenidos de lobectomía. Conclusiones: La implementación de un programa intensivo de fisioterapia postoperatoria basado en ejercicios respiratorios reduce el riesgo de desarrollar CPP y la DEH en pacientes lobectomizados
Objective: To evaluate the effects of an intensive postoperative physiotherapy program focused on respiratory exercises in patients undergoing lobectomy by open thoracotomy. Design: Quasi-experimental study. Setting: Tertiary referral academic hospital. Participants: 208 patients undergoing lobectomy by open thoracotomy. Interventions: Control group patients (n = 102) received standard medical/nursing care, and experimental group patients (n=106) added to the standard clinical pathway a daily physiotherapy program focused on respiratory exercises until discharge. Outcomes: Analyzed outcomes were the frequency of postoperative pulmonary complications (PPCs) more amenable to physiotherapy (pneumonia, atelectasis and respiratory insufficiency) and length of hospital stay (LOS). Results: Both groups were comparable regarding preoperative and surgical characteristics. Incidence of PPCs was 20.6% in control and 6.6% in experimental group (P = .003). Median (IQR) LOS in control group was 14 (7) days (Huber M estimator 14.21) and 12 (6) days (Huber M estimator 12.81) in experimental. Logistic regression model identified the evaluated physiotherapy program (P = .017; EXP [B] 95% CI 0.081-0.780) and % FEV1 (P = .042; EXP [B] 95% CI 0.941-0.999) as protective factors for the development of PPCs in patients undergoing lobectomy. Conclusions: Implementing a postoperative intensive physiotherapy program focused on respiratory exercises reduces the risk of PPCs and resultant LOS on patients undergoing lobectomy

BACKGROUND CONTEXT: Experimental studies suggest that catastrophizing may worsen the prognosis of low back pain (LBP) and LBP-related disability and increase the risk of chronicity. PURPOSE: To assess the prognostic value of baseline catastrophizing for predicting the clinical evolution of LBP patients in routine clinical practice and the association between the evolution of pain and catastrophizing. STUDY DESIGN/SETTING: Prospective study in routine clinical practice of the Spanish National Health Service. PATIENT SAMPLE: One thousand four hundred twenty-two acute and chronic adult LBP patients treated in primary and hospital care. OUTCOME MEASURES: Pain, disability, and catastrophizing measured through validated instruments. METHODS: Patients were managed according to routine clinical practice. Outcome measures were assessed at baseline and 3 months later. Logistic regression models were developed to estimate the association between baseline catastrophizing score and the improvement of LBP and disability, adjusting for baseline LBP and leg pain (LP) severity, disability, duration of the pain episode, workers' compensation coverage, radiological findings, failed back surgery, and diagnostic procedures and treatments undertaken throughout the study. Another model was developed to estimate the association between the evolution of LBP and the change in catastrophizing, adjusting for the same possible confounders plus the evolution of LP and disability. Models were repeated excluding the treatments undergone after the baseline assessment. RESULTS: Regression models showed that the degree of baseline catastrophizing does not predict the evolution of LBP and disability. Conversely, as the degree of pain improvement increases, so does the odds ratio for improvement in catastrophizing, ranging from three (95% confidence interval [95% CI], 2.00-4.50; p<.001) for improvements in pain between 1.1 and 4 visual analog scale (VAS) points, to 7.3 (95% CI, 3.49-15.36; p<.001) for improvements in pain more than 6.1 VAS points. Similar results were obtained when treatments were excluded from the models. CONCLUSIONS: In routine practice, assessing the baseline score for catastrophizing does not help clinicians to predict the evolution of LBP and disability at 3 months.

STUDY DESIGN: Correlation between variables measured with previously validated instruments. OBJECTIVE: To explore the association between catastrophizing and disability in patients treated for subacute or chronic low back pain (LBP) within routine clinical practice in Spain. SUMMARY OF BACKGROUND DATA: The influence of psychological variables on LBP-related disability in Southern Europe is different to the one in the Anglo-Saxon and Northern European cultural environments. In Spanish LBP patients, the influence of fear avoidance beliefs on disability is negligible, and catastrophizing does not mediate the improvement of disability caused by active education. The association between catastrophizing and dis-ability is unknown. METHODS: Thirty-three clinicians working for the Spanish National Health Service in 6 primary care and 8 specialty centers, recruited 1461 patients seeking care for subacute and chronic LBP. Patients were assessed only once. A linear regression model was developed to assess the percentage of the variance of disability explained by gender, age, chronicity status, severity of LBP, severity of referred pain (referred pain down to the leg), catastrophizing, eligible for workers' compensation (yes/no), failed back surgery (yes/no), radiologic findings, and treatments. RESULTS: Correlations among LBP, referred pain down to the leg, disability, and catastrophizing were moderate, but significant. The strongest one was between disability and catastrophizing (r ∇ 0.520). Catastrophizing explained 28% of disability, whereas severity of LBP only 3%. Global adjusted R of the model was 0.387. There was an association between some radiologic findings and treatments, and slightly higher levels of disability. CONCLUSION: In Southern European subacute and chronic LBP patients, catastrophizing correlates with dis-ability and explains approximately one-fourth of its variance. Further studies should assess its value as a prognostic factor in subacute and chronic patients.
