“…The validity and reliability of MACS classification has been well-established, and ranges from level I (the child handles most objects), to level V (the child cannot handle any object) for children aged 4 to 18 years [9]. Korean versions of PEDI and MACS are widely used, both of which have also been shown to be valid and reliable [1011]. …”

ObjectiveTo investigate the factors influencing the development of self-care activity, and the association between mobility and self-care activity in children with cerebral palsy (CP).MethodsA total of 63 CP children aged ≥4 years, were studied retrospectively. Children with severe intellectual disability or behavioral problems were excluded. The relationship between the Gross Motor Function Classification System (GMFCS), the Manual Ability Classification System (MACS), and the Pediatric Evaluation of Disability Inventory (PEDI) was analyzed. Simple and multiple linear regression analyses were conducted for continuous variables, such as verbal intelligence quotient (IQ) and PEDI subscales.ResultsFinal evaluation was done for 25 children, ranging from 4 to 11 years of age. According to GMFCS levels, the differences in PEDI-self-care scores, showed statistically borderline significance (p=0.051). Conversely, differences in PEDI-self-care scores according to CP types and MACS levels were not statistically significant. Simple linear regression analysis showed that PEDI mobility and PEDI social function significantly influence the PEDI self-care. Multiple linear regression analysis showed that PEDI mobility was the only factor significantly influencing PEDI self-care in children aged ≥7 years (R2=0.875, p=0.03).ConclusionMobility is important for the acquisition of self-care abilities in children with CP aged ≥7 years.

“…In several studies, the inter-and intrarater reliability of the MACS has been found to be good to excellent between therapists as well as between parents and therapists, varying from 0.73 to 0.98 and 0.91 to 0.98 respectively. 2,[4][5][6][7][8][9][10][11] There is also evidence supporting the stability of MACS classifications over a short period. In a previous study, the intraclass correlation coefficient (ICC) was high (0.92) and 67% of the children remained at the same level over a period of 1 year when scored by caregivers.…”

ABBREVIATION MACSManual Ability Classification System AIM To evaluate the stability over time of the Manual Ability Classification System (MACS) levels.METHOD The study group comprised 1267 children with cerebral palsy (746 males, 521 females) who were followed from 2005 to 2010 with two or more registered MACS classifications rated at least 1 year apart. Thirty-five percent of the children (n=445) had four MACS registrations. The children were between 4 and 17 years old at their first rating, The stability over time was also compared between children who were younger (4y of age) or older (≥10y) at the time of their first classification.RESULTS An excellent stability was found between two ratings at 1-year intervals with an intraclass correlation coefficient (ICC) of 0.97 (95% CI 0.97-0.97) and 82% agreement (n=1267). The stability was also excellent for two ratings performed 3 to 5 years apart (ICC 0.96; 95% CI 0.95-0.97) with an agreement of 78% (n=445). Across four ratings, 70% of the children remained at the same level. The results were similar for younger and older children, indicating that stability was not influenced by age.INTERPRETATION This study provides evidence that MACS levels are stable over time and that the classification has predictive value.Cerebral palsy (CP) is a clinical description and by definition; a permanent disorder of the development of movement and posture, causing activity limitation, attributed to non-progressive disturbances that occurred in the developing fetal or infant brain. 1 The motor disorder in CP is often accompanied by disturbances of sensation, perception, cognition, communication, and behavior, by epilepsy, and by secondary musculoskeletal problems.1 This description gives no information about the children's functional ability, and it has been suggested that the diagnosis of CP should be used together with functional classifications.1 One of these classifications is the Manual Ability Classification System (MACS) 2 that has been widely used in recent years, both in clinical practice and in research. However, further investigation is required to determine whether or not children remain at the same MACS level during development and growth and to establish if the MACS ratings have predictive value.The MACS consists of five levels and was designed to classify how children with CP aged 4 to 18 years use their hands when handling objects in daily activities.2 Children at MACS level I handle most objects easily and successfully. At MACS level II, they handle most objects but with somewhat reduced ability and/or speed. Children at MACS levels III to V need assistance to different degrees. At MACS level III, children handle objects with difficulty and require help in preparing and/or modifying activities. Children at MACS level IV can handle a limited selection of easily managed objects in adapted situations. At MACS level V, children cannot handle objects and have severely limited ability to perform even the simplest of actions. Further descriptions of the MACS levels can b...

“…Besides, health professional vs. patient self-evaluation data were collected in order to compare results of QUIP-RS Brazil from health professional and patients self-evaluation. 17 There was a time difference from 20 min to 30 min between both measurements (firstly professional and subsequently patient self-evaluation). Both measurements were performed during the morning.…”

Parkinson's disease (PD) has numerous motor and non-motor symptoms. Among non-motor manifestations impulse control disorders (ICDs) stand out. ICDs include compulsions for gambling, shopping, eating, and sexual behavior, and "related disorders" such as hobbyism, simple motor activities, and dopamine dysregulation syndrome. There is no rating scale translated and adapted transculturally into Brazilian Portuguese language. Therefore, we cross-culturally adapted and investigated the measurement properties of the Brazilian version of the Questionnaire for Impulsive-Compulsive Disorders in Parkinson's Disease-Rating Scale (QUIP-RS). Fifty-three patients participated in the study. Inter-evaluator and test-retest (patient and health professional) reliabilities (intraclass correlation coefficient) were all excellent (0.93, 0.93, and 0.99). The internal consistency was high (α = 0.92). The Minimal detectable change (MDC) value was 5.8 (patient) and 2.3 (health professional) points. There was a floor, but no ceiling, effect. In summary, the Brazilian version of the QUIP-RS has high reliability and content validity.
