Quality of life assessment instruments in children and adolescents with neuromuscular diseases: a systematic scoping review.

OBJECTIVE: (1) To identify instruments used to assess quality of life (QoL) in children and adolescents with neuromuscular diseases; (2) To identify the psychometric properties contained in these instruments. METHODS: This is a scoping review in which the electronic databases Embase, Scielo, Scopus, Pubmed and Lilacs were used as well as grey literature. The following terms were used in the search for articles published in the last 10 years: children, adolescents, neuromuscular disease, and quality of life. RESULTS: In total, 15 articles were included and evaluated, indicating 7 instruments used to assess QoL (PedsQL™ Inventory 3.0 Neuromuscular Module, the PedsQL™ 4.0, the PedsQL DMD Module, the PedsQL ™ MFS, the SOLE, the KIDSCREEN and the LSI-A). The number of items ranged from 17 to 45. In addition, 6 instruments showed psychometric properties, but only 2 showed good and high quality, either in internal reliability or reproducibility. CONCLUSION: Our results were able to map the main QoL assessment instruments of children and adolescents with neuromuscular disease and the most cited instrument was the PedsQL™ Inventory 3.0 Neuromuscular Module. Larger studies that assess psychometric properties and that are validated for most diseases are needed.

Cross-cultural adaptation and concurrent validity of the children's OMNI scale of perceived exertion for Arm-Crank activity in Spina Bifida.

PURPOSE: To perform a cross-cultural adaptation of the OMNI verbal descriptors to Brazilian-Portuguese and examine the validity of the Brazilian version for arm-crank activity. MATERIALS AND METHODS: Cross-cultural adaptation stages were: permission, translation, synthesis, back translation, expert committee review, pretesting, and submission and appraisal. For the concurrent validity, a Brazilian OMNI-Wheel scale was used to obtain rating of perceived exertion for the overall body (RPEOverall) and arms (RPEArms) in participants (n = 9, 10-17 years) with spina bifida. Cardiopulmonary exercise test was used to measure heart rate (HR) and oxygen uptake (VO2). Repeated Measures Correlation (rrm) was used to examine the scale validity. RESULTS: The cross-cultural adaptation produced equivalence between English and Brazilian-Portuguese verbal descriptors based on successful translation and pretesting. The Brazilian OMNI-wheel was validated based on strong associations of RPEOverall with VO2 (rrm (35) = 0.86, 95% CI [0.93, 0.73], p < 0.001) and HR (rrm (35) = 0.89, 95% CI [0.94, 0.79], p < 0.001) and RPEArms with VO2 (rrm (33) = 0.82, 95% CI [0.91, 0.66], p < 0.001) and HR (rrm (33) = 0.82, 95% CI [0.91, 0.66], p < 0.001). CONCLUSIONS: The OMNI scale was cross-culturally adapted to Brazilian-Portuguese. The Brazilian OMNI-Wheel was validated based on strong associations of RPE with HR and VO2. Implications For RehabilitationThe original English OMNI was cross-culturally adapted to Brazilian-Portuguese.A Brazilian wheelchair OMNI was concurrently validated for Arm-Crank Activity in adolescents with spina bifida.This OMNI scale version may aid health providers in monitoring perceived exertion in Brazil.

Translation and cross-cultural adaptation of the Charcot-Marie-Tooth disease Pediatric Scale to Brazilian Portuguese and determination of its measurement properties.

BACKGROUND: The Charcot-Marie-Tooth disease Pediatric Scale (CMTPedS) has been used to measure aspects of disability in children with all types of Charcot-Marie-Tooth disease (CMT). OBJECTIVE: To translate and cross-culturally adapt the CMTPedS into Brazilian-Portuguese and determine its reliability and validity. METHODS: The translation and cross-cultural adaptation followed international guidelines recommendations. Twenty individuals with CMT were assessed. Two examiners assessed the participants for inter-rater reliability. Face validity was assessed by eight physical therapists that judged the relevance of each test item. The Bland-Altman analysis (bias) and standard error of measurement (SEM) complemented the analysis. Furthermore, intraclass correlation coefficients (ICC), weighted kappa (k), and internal consistency (Cronbach's alpha) was determined. RESULTS: The CMTPedS was successfully translated and cross-culturally adapted. Twenty children/youth were enrolled in the study. Of these, the majority (55%) were girls with a mean age of 13.9 (range: from 6 to 18) years. Regarding face validity, the CMTPedS-Br showed relevant items for assessing children and youth with CMT. The ICC for the total score showed excellent reliability (ICC2.1  = 0.93, 95% CI = 0.84, 0.97). The most reliable items were grip, dorsiflexion and plantar flexion strength while the least reliable items were pinprick, vibration, and gait. The internal consistency was excellent (α = 0.96, 95% CI = 0.91, 0.99) and the agreement showed small variability (bias = 0.15, 95% CI= -4.28, 4.60). CONCLUSION: The CMTPedS-Br showed adequate reliability and face validity to measure disability in individuals with CMT. This tool will allow Brazil to be part of multicentered studies on such a rare but debilitating condition.
