Spanish Version of the Anterior Cruciate Ligament-Quality of Life Questionnaire: Translation, Cross-cultural Adaptation, and Validation.

Background: The Anterior Cruciate Ligament-Quality of Life (ACL-QOL) questionnaire is a patient-reported outcome measure used to assess the effect of an anterior cruciate ligament (ACL) injury on the lives of patients. It was originally written in English, which may affect its use when completed by nonnative English speakers. Purpose: To translate and adapt the ACL-QOL to Spanish and provide evidence of its psychometric properties. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: A total of 183 patients with an ACL injury from 4 Catalan hospitals were included: 99 patients who had undergone ACL reconstruction (ACLR) completed the Spanish version of the ACL-QOL (ACL-QOL-Sp) twice (mean interval, 15.2 days) in 2 weeks for test-retest reliability, and 84 patients completed the ACL-QOL-Sp, the Lysholm knee scoring scale, the Knee injury and Osteoarthritis Outcome Score (KOOS), Tegner Activity Scale, and the 12-item Short Form Health Survey (SF-12) before and at 4 and 9 months after ACLR to assess responsiveness. The association between the ACL-QOL-Sp and the other outcome measures was evaluated with the Spearman correlation coefficient. Results: The ACL-QOL-Sp showed good internal consistency (Cronbach alpha = 0.96) and test-retest reliability (intraclass correlation coefficient = 0.97). The standard error of measurement was 3.6, also suggesting the precision of measurements. The smallest detectable change was 9.98 in 94% of patients. No association was found between the ACL-QOL-Sp score and the Tegner score or SF-12 mental component summary score; however, a moderate correlation was found with the overall KOOS score (r = -0.545), Lysholm score (r = 0.509), and SF-12 physical component summary score (r = 0.607). The correlation ranged from weak for the KOOS-Symptoms subscore (r = -0.290) to moderate for the KOOS-Quality of Life subscore (r = -0.698). No ceiling or floor effects were observed. The ACL-QOL-Sp showed a moderate effect size (0.73) at 4 months but a large effect size (1.70) at 9 months. Conclusion: The ACL-QOL-Sp showed adequate internal consistency, test-retest reliability, and responsiveness in evaluating quality of life after ACLR in Spanish-speaking patients.

Reliability and Diagnostic Accuracy of a New Vaginal Dynamometer to Measure Pelvic Floor Muscle Strength.

AIMS: Assess the intrarater and interrater reliabilities and diagnostic accuracy of a new vaginal dynamometer to measure pelvic floor muscle (PFM) strength in incontinent and continent women. METHODS: A test-retest reliability study including 152 female patients. EXCLUSION CRITERIA: history of urge urinary incontinence, prolapse of pelvic organ, pregnancy, previous urogynecological surgery, severe vaginal atrophy, or neurological conditions. The examination comprised digital assessment using the modified Oxford scale (MOS) and dynamometry measurements with a new prototype hand-held dynamometer. The MOS score ranges from 0 to 5: 0, no contraction; 1, flicker; 2, weak; 3, moderate; 4, good; 5, strong. Examinations were performed by a physiatrist, a physiotherapist and a midwife. The rest period between each rater measurement was 5 minutes. Assessment of intrarater and interrater reliability was calculated with the intraclass correlation coefficient. RESULTS: One hundred twenty-two incontinent women and 30 continent women were included. Scores between 0 and 2 in MOS were recorded in 72% of incontinent women versus 20% in continent patients (P < 0.001). Intrarater reliability of the dynamometer was 0.942 (95% confidence interval [CI], 0.920-0.958) and the interrater reliability was 0.937 (95% CI, 0.913-0.954). The analysis of variance analysis showed significant differences in PFM strength across digital assessment categories. The post-hoc analysis showed statistical differences between adjacent categories of MOS 1-2 and 2-3. The diagnostic accuracy showed an area under the curve of 0.82 (95% C,: 0.75-0.89), 0.87 (95% CI, 0.81-0.92), and 0.83 (95% CI, 0.77-0.90) for the physiatrist, midwife, and physiotherapist, respectively. CONCLUSIONS: The results obtained show a good reliability and validity of this new vaginal dynamometer to quantify PFM strength.

Inter-rater reliability of the digital palpation of pelvic floor muscle by the modified Oxford Grading Scale in continent and incontinent women. / Fiabilidad inter evaluador de la palpación digital de los músculos del suelo pélvico utilizando la escala modificada de Oxford graduada en mujeres continentes e incontinentes.

OBJECTIVE: The first choice treatment in stress urinary incontinence (SUI) is rehabilitation of the pelvic floor in order to improve muscle strength. However, no entirely reliable instruments for quantifying pelvic floor muscle (PFM) strength are currently available. Our aim was to test the inter-rater reliability of the Modified Oxford Scale (MOS) used as the gold standard for measuring PFM strength. METHODS: Test-retest reliability study. One hundred and twenty-two women with SUI and thirty continent women were recruited. Patients were excluded if they had a history consistent with pelvic organ prolapse, pregnancy, previous urogynaecological surgery, or neurological conditions. Bidigital palpation quantified by the MOS was carried out by three independent examiners. Each subject answered a two-part questionnaire: demographic and clinical characteristics and the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF). The Cohen's Kappa index with quadratic (Kw) weighting was used to assess the inter-rater agreement. RESULTS: 122 incontinent and 30 continent women were included. MOS ranged between 0 and 2 in 72.2% incontinent and 19.5% of continent women. The degree of agreement was substantial in the group of incontinent women (Kw between 0.73 and 0.81) and moderate in the group of continent women (Kw between 0.55 and 0.72). CONCLUSIONS: Our results suggest that the inter-observer reliability of MOS is improbable, especially in continent women.

OBJETIVO: El tratamiento de primera elección en la incontinencia urinaria de esfuerzo es la rehabilitación del suelo pélvico con el fin de mejorar la fuerza muscular. Sin embargo, actualmente no se dispone de instrumentos totalmente fiables para cuantificar la fuerza de la musculatura del suelo pélvico. Nuestro objetivo fue determinar la fiabilidad interobservador de la Escala de Oxford Modificada (MOS) utilizada como el patrón oro para medir la fuerza. MÉTODOS: Estudio de fiabilidad test-retest. Se reclutaron ciento veintidós mujeres con Incontinencia Urinaria de Esfuerzo y treinta mujeres continentes. Las pacientes fueron excluidas si presentaban: prolapso de órganos pélvicos, embarazo, cirugía uroginecológica previa, o enfermedades neurológicas. La palpación bidigital cuantificada con la Escala de Oxford Modificada fue realizada por tres examinadores independientes. Cada sujeto respondió a un cuestionario en dos partes: características demográficas y clínicas y el International Consultation on Incontinence Questionnaire-Forma abreviada (ICIQ-SF). Se utilizó el índice de Kappa de Cohen con ponderación cuadrática (Kw) para evaluar el acuerdo entre evaluadores. RESULTADOS: El MOS osciló entre 0 y 2 en el 72,2% de incontinentes y el 19,5% de las mujeres continentes. El grado de concordancia fue considerable en el grupo de mujeres incontinentes (Kw entre 0,73 y 0,81) y moderado en el grupo de mujeres continentes (Kw entre 0,55 y 0,72).CONCLUSIÓN: Nuestros resultados sugieren que la fiabilidad interobservador de la MOS es mejorable, especialmente en las mujeres continentes.

Intra-rater reliability and diagnostic accuracy of a new vaginal dynamometer to measure pelvic floor muscle strength in women with urinary incontinence.

AIMS: The first choice treatment in urinary incontinence (UI) is rehabilitation of the pelvic floor in order to improve muscle strength. However, no entirely reliable instruments for quantifying pelvic floor muscle (PFM) strength are currently available. Our aim was to test the intra-rater reliability and diagnostic accuracy of a new vaginal dynamometer for measuring PFM strength. METHODS: Test-retest reliability study. One hundred and four women with stress urinary incontinence (SUI) were recruited. Patients were excluded if they had a history consistent with urge urinary incontinence or pelvic organ prolapse, pregnancy, previous urogynecological surgery, severe vaginal atrophy, or neurological conditions. The examination comprised digital palpation quantified by the modified Oxford scale and by two consecutive dynamometry measurements obtained using a new prototype dynamometer. This instrument comprises a speculum in which an inductive displacement sensor (LVDTSM210.10.2.KTmodel, Schreiber) is attached to a spring of known stiffness constant (k). The intraclass correlation coefficient (ICC) was calculated to assess intra-rater reliability. Diagnostic accuracy was assessed using Receiver Operating Characteristics (ROC) curves analysis. RESULTS: Of the 104 subjects included, 59.6% presented scores between 0-2 on the Oxford scale. Intra-rater reliability was 0.98 (95%CI: 0.97-0.99). In the Bland & Altman plot, the distribution of disagreements was similar in the lowest and the highest strength values. The diagnostic accuracy of the dynamometer with regard to digital palpation showed an area under the curve of 0.85 (95%CI: 0.77-0.93). CONCLUSIONS: Our results suggest that this new vaginal dynamometer is a reliable and valid instrument for quantifying PFM strength. Neurourol.

[Validation of the Spanish version of the King's Health questionnaire for evaluating quality of life related to urinary incontinence in patients with spinal cord injury]. / Validación de la versión española del cuestionario King's Health para la evaluación de la calidad de vida relacionada con la incontinencia urinaria en pacientes con lesión medular.

BACKGROUND AND OBJECTIVE: To determine the validity of the Spanish version of the King's Health Questionnaire (KHQ) in patients with spinal cord injury. PATIENTS AND METHODS: A cross-sectional study, including a total of 120 patients with spinal cord injury. The feasibility, cross-cultural validity, and internal consistency of the KHQ were evaluated. RESULTS: The dimensions with the highest scores were: impact of urinary symptoms, personal relations, and physical limitations. The following groups presented a significantly poorer HRQoL: persons of advanced age in personal relations (P=0.042), women in limitations of daily life activities (P=0.009) and in the impact of urinary incontinence (P<0.01), paraplegic patients in personal relations, and patients with incomplete cord lesions in sleeping and energy (P<0.01). Patients with an external condom catheter presented a better HRQoL with significant differences in the dimension, limitations of daily life activities (P=0.04). The KHQ showed good internal consistency (Cronbach alpha 0.91). CONCLUSION: KHQ is a valid instrument for evaluating HRQoL related with urinary incontinence in patients with spinal cord injury.

[Efficacy and safety of botulinum toxin in external urethral sphincter by transperineal way guided transrectal ultrasound and electromyography on chronic urinary retention due to spinal cord injury]. / Eficacia y seguridad de la toxina botulínica administrada en el esfínter uretral externo vía transperineal guiada mediante ecografía transrectal y electromiografía en la retención urinaria crónica secundaria a una lesión medular.

BACKGROUND: To assess the efficacy and safety of botulinum toxin for sphincter hypertonia in patients with spinal cord injury (SCI). PATIENTS AND METHODS: Non-control clinical trial on men with neurogenic detrussor-sphincter dyssynergia (DSD) due to SCI. 100 IU of Botox® were injected through the transperineal way on external urethral sphincter under electromyography and transrectal ultrasound guidance. The following parameters were determined: post-void residual (PVR), maximum urethral pressure (MUP), miction volume (M) and miction percentage (MP). The incidence of erectile dysfunction was evaluated using the International Index of Erectile Function questionnaire (IIEF-5 items). RESULTS: 19 men with an average age of 40 years (ED 22-56) were included. The average time of monitoring was 546 days (20 months). As an average, an infiltration was done every 6 months, with an average of 2.7 infiltrations per patient (1-7). PVR dropped by 59.3 ml, p=0.03; miction raised to 52 ml, p=0.018; MP was improved by 17.2%, p=0.011. Changes on MUP were not significant. Erectile dysfunction was not worse than the initial one (IIEF-5: 11.4 to 13). CONCLUSION: The infiltration of the toxin into the sphincter through the transperineal way seems to be an effective and safe therapeutic option.
