본 연구의 목적은 수정된 노팅엄 감각평가(rNSA)를 한국판으로 번역하고 검증하는 것이었다. 수정된 rNSA를 한국어로 번역하기 위해 번안/역번안 과정을 사용하여 단면 연구가 수행되었고, 한국판 rNSA의 유효성을 조사하기 위하여 평가자간 및 평가자내 신뢰도, 내적일관성 및 동시타당도를 조사하였다. 한국판 rNSA는 평가자간 신뢰도(r=0.92-1.00), 평가자내 신뢰도(r=0.93-1.00)로 높은 신뢰도를 확인하였고, 한국판 Fugl Meyer의 감각항목과의 유의한 상관관계(r=0.96)를 확인하였다. 한국판 rNSA의 내적일치도에 대한 Cronbach 값은 0.73-0.90의 범위이고, 한국판 Fugl Meyer의 감각항목의 Cronbach 값은 0.70-0.88의 범위였다. 이 결과로, 한국판 rNSA의 신뢰도 및 타당도를 확인하였으며, 임상환경에서 뇌졸중 이후 감각기능을 평가하는 것이 가능할 수 있다고 생각한다.

Abstract ▼ AI-Helper

The aim of this study was to translate and validate the revised Nottingham Sensory Assessment(rNSA) in Republic of Korea. A cross-sectional study was conducted to translate the rNSA into Korean using a modified forward/backward translation procedure. Inter-rater and intra-rater reliability, internal consistency, and concurrent validity were investigated to validate the Korean version rNSA. The Korean version rNSA showed excellent inter-rater reliability (r=0.92-1.00) and intra-rater reliability (r=0.93-1.00). Significant correlations were found between sensory assessment results of the Korean version of the rNSA and the Korean Fugl Meyer Assessment Sensory subscales (r=0.96). The Cronbach α value of internal consistency of Korean version rNSA was ranged from 0.73 to 0.90, the value of K-FMA-S was ranged from 0.70 to 0.88. In these results, psychometric properties of the Korean version of the rNSA achieved the standard level and can be feasible in clinical practice to assess sensory function following stroke in Republic of Korea.

문제 정의

The purpose of the current study was to translate the rNSA into Korean with cultural adaptation and to validate its reliability and validity in hemiparetic patients after stroke.
This was the first study to investigate the reliability and validity of the K-rNSA. These findings may support the use of the K-rNSA by clinicians and researchers as a comprehensive measure to evaluate somatosensory impairments in people with stroke.

가설 설정

A few limitations of the study warrant consideration. 1) The validity of translation study experts may be deteriorated. In future studies, it is necessary to use the Delphi method to increase the validity of the tools.

제안 방법

In future studies, it is necessary to use the Delphi method to increase the validity of the tools. 2) The purpose of K-rNSA was to identify sensory problems after stroke, and this study was intended to confirm reliability and validity, including all lesions, because it could affect sensory damage in several lesions due to stroke. Although this study was conducted with a small number of subjects, it was not possible to generalize, but it is thought that follow-up studies will be needed with a large number of subjects.
The stereognosis category includes 11 items and is scored as follows: 0 indicates no sense, 1 indicates impaired sense, and 2 indicates normal sense. Assessment items included: a filament(green) for light touch, tubes(cold, hot) for temperature test, powder for tactile sense, 50, 100, and 500 won coins, a ballpoint pen, a pencil, a comb, scissors, a sponge, fabric, and cup for stereognosis.
Intra-rater and inter-rater reliability were analyzed in this study to confirm reliability of the K-rNSA. Based on the 95% confident interval of the Intraclass correlation coefficients estimate, values less than 0.
Another occupational therapist with over 5 years clinical experience checked for the appropriateness of terminology, comprehension of the assessment, and if the translation was written in a clear and natural manner. The occupational therapist who involved in revision described the revised contents with the original contents and sent the revision to the authors of this article and then rNSA was completed for the first draft of Korean version of revised Nottingham Sensory Assessment(K-rNSA).
The present study translated rNSA into Korean, and analyzed the inter-rater and intra-rater reliability, internal consistency, and concurrent validity of the K-rNSA using thirty Korean stroke patients. The research team followed the frequently used multi-step approach to improve translation quality[16].
This study applied translation with cultural adaptation and backward translation, and psychometric evaluation.

대상 데이터

To test the validity and reliability of the K-rNSA, thirty participants were recruited from St. Vincent’s hospital in Suwon city of the Republic of Korea from January 5 to January 19, 2015.

데이터처리

The descriptive analysis of the numerical and categorical variables of the sample was done. Inter-rater reliability and intra-rater reliability were analyzed by intraclass correlation coefficients(ICCs). Internal consistency was computed by the Cronbach ɑ.
Internal consistency was computed by the Cronbach ɑ. To evaluate concurrent validity, spearman correlation coefficients were calculated by using total data for the sensory categories of the K-FMA and K-rNSA. The significance level was set at 0.
To test the concurrent validity of the K-rNSA, spearman correlation coefficient was analyzed between the results of K-rNSA and K-FMA-S. There was a strong correlation between the total score of the K-FMA-S the K-rNSA.

이론/모형

95) were good to excellent between the rNSA and the FMA-S[19]. The rNSA proprioception measure was a predictor for the FMA-S[20].

성능/효과

A study of translation and verification on the K-FMA-S showed both good inter-rater reliability (ICC=0.992, 95% CI=0.987-0.995) and test-retest reliability (ICC=0.883, 95% CI=0.798-0.932)[15].
963. From the results, the authors concluded that the K-rNSA demonstrates strong reliability and validity for the majority of the subtests, indicating acceptability for use in clinical practice.
