Background and PurposeDistinguishing between a clinically significant change and change due to measurement error can be difficult. The purpose of this study was to determine test-retest reliability and minimal detectable change for the Berg Balance Scale (BBS), forward and backward functional reach, the Romberg Test and the Sharpened Romberg Test (SRT) with eyes open and closed, the Activities-specific Balance Confidence (ABC) Scale, the Six-Minute Walk Test (6MWT), comfortable and fast gait speed, the Timed “Up & Go” Test (TUG), the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36), and the Unified Parkinson Disease Rating Scale (UPDRS) in people with parkinsonism.SubjectsThirty-seven community-dwelling adults with parkinsonism (mean age=71 years) participated. The Hoehn and Yahr Scale median score of 2 was on the lower end of the scale; however, the scores ranged from 1 to 4.MethodsSubjects were tested twice by the same raters, with 1 week between tests. Test-retest reliability was calculated using intraclass correlation coefficients (ICCs). Minimal detectable change was calculated using a 95% confidence interval (MDC95).ResultsThe ICCs for test-retest reliability were above .90 for the BBS, ABC Scale, SRT with eyes closed, 6MWT, and comfortable and fast gait speeds. The MDC95 values for those functional tests were: BBS=5/56, ABC Scale=13%, SRT with eyes closed=19 seconds, 6MWT=82 m, comfortable gait speed=0.18 m/s, and fast gait speed=0.25 m/s. The ICCs for test-retest reliability of SF-36 scores were above .80, with the exception of the social functioning subscale. The MDC95 values for the SF-36 ranged between 19% and 45%. The MDC95 values for the UPDRS Activities of Daily Living section, Motor Examination section, and total scores were 4/52, 11/108, and 13/176, respectively.Discussion and ConclusionMinimal detectable change values are useful to therapists in rehabilitation and wellness programs in determining whether change during or after intervention is clinically significant. High test-retest reliability of scores for the BBS, ABC Scale, SRT with eyes closed, 6MWT, and gait speed make them trustworthy functional assessments in people with parkinsonism. The SF-36 and UPDRS provide quality-of-life and disease severity rating values in the ongoing assessment of people with parkinsonism.

“…It indicates the patient's self-perceived level of handicap associated with their dizziness on a total score (range 0-100) on a 3-step scale (yes = 4 points, sometimes = 2 points and no = 0 points). The German version of the DHI demonstrated good reliability (test-retest reliability r = 0.92-0.97) and internal consistency (α = 0.72-0.89) and is thus recommended as a measure of disability in patients with dizziness [36,37]. …”

Background: Alexithymia is a personality trait characterized by deficits in regulating, experiencing and verbalizing emotions and has been assumed to be associated with a tendency to express emotional arousal through somatization. Although such a tendency is often observed in patients with dizziness, the exact relationship of alexithymia to dizziness is not yet known. The aim of this study was to examine alexithymic characteristics in patients with dizziness and its relation to health-related quality of life (HRQoL). Sampling and Methods: We assessed 208 patients from an interdisciplinary center for vertigo and balance disorders for characteristics of alexithymia (20-item Toronto Alexithymia Scale), HRQoL (Short-Form 12 Health Survey, SF-12), dizziness (Dizziness Handicap Inventory), depression and anxiety (Hospital Anxiety and Depression Scale). Hierarchical regression analyses were used to evaluate the relationship between alexithymia, dizziness and HRQoL. Results: We found that difficulties in identifying and describing feelings, two important factors of alexithymia, were significantly related to more severe symptoms of dizziness. More pronounced alexithymic characteristics were associated with lower HRQoL, especially in the mental dimension of the SF-12. The results remained significant after controlling for possibly confounding variables such as socioeconomic status and depression. Conclusions: These findings contribute to a better understanding of affect regulation in patients with dizziness, which is important for the development of psychotherapeutic interventions suitable for alexithymic patients with dizziness.

“…The physical insecurity generated by the chronic dizziness and by the lack of body balance may lead to irritability, loss of self-confidence, fear to go out alone, fear of a serious disease, sensation of being out of reality, besides anxiety, depression or panic (Yardley & Putman, 1992;Ganança & Caovilla, 1998a;Ganança et al, 2000). The vestibular system's disorders besides generating physical and emotional problems, may provoke incapacity for performing professional, social and domestic activities, worsening the quality of life (QOL) of these patients (Enloe & Shields, 1997;Ganança et al, 2002).…”

TEMA: impacto da tontura na qualidade de vida (QV). OBJETIVO: adaptar culturalmente o Dizziness Handicap Inventory (DHI) para aplicação na população brasileira, avaliar sua reprodutibilidade e descrever os resultados obtidos à aplicação deste questionário em pacientes com tontura crônica. MÉTODO: o DHI foi aplicado, inicialmente, em 45 pacientes com tontura crônica e hipótese diagnóstica de síndrome vestibular, seguindo as etapas de tradução do idioma Inglês para o Português e adapatação lingüística, revisão da equivalência gramatical e idiomática, adaptação cultural e avaliação da reprodutividade intra e interpesquisadores. A avaliação da reprodutividade foi realizada por intermédio do teste de pesquisadores. A avaliação da reprodutividade foi realizada por intermédio do teste de Wilcoxon para duas amostras dependentes, P < 0,05. O instrumento foi aplicado para um total de 250 pacientes para avaliação do impacto da tontura na qualidade de vida de vestibulopatas crônicos. RESULTADOS: a versão brasileira do DHI (DHI brasileiro) foi bem compreendida pelo população estudada. Não foi verificada diferença estatística significante à avaliação da reprodutibilidade inter-pesquisadores (P = 0,418) e intra-pesquisadores (P = 0,244). Todos pacientes apresentaram prejuízo na QV e os aspectos físicos foram os mais prejudicados, seguidos em ordem decrescente pelos aspectos funcionais e emocionais. Os aspectos funcionais mostraram-se mais comprometidos em indivíduos mais velhos. Nenhuma associação foi verificada entre o gênero e as médias do escore total e de cada um dos aspectos avaliados pelo DHI. CONCLUSÃO: o DHI foi adaptado culturalmente para aplicação na população brasileira (DHI brasileiro), mostrando-se confiável para a avaliação da interferência da tontura na QV. Os pacientes com tontura crônica e hipótese diagnóstica de síndrome vestibular apresentaram prejuízo na QV devido a este sintoma, verificados à aplicação do DHI brasileiro. Os aspectos físicos foram os mais prejudicados.
