“…The shortest time of three trails was considered the best and therefore was used in the results (Podsiadlo and Richardson 1991). The test-retest reliability and inter-rater reliability were ICC ¼0.80 and r ¼ 0.99, respectively (Lim et al 2005).…”

Postural instability is one of the most incapacitating symptoms of Parkinson's disease (PD) and appears to be related to cognitive deficits. This study aims to determine the cognitive factors that can predict deficits in static and dynamic balance in individuals with PD. A sociodemographic questionnaire characterized 52 individuals with PD for this work. The Trail Making Test, Rule Shift Cards Test, and Digit Span Test assessed the executive functions. The static balance was assessed using a plantar pressure platform, and dynamic balance was based on the Timed Up and Go Test. The results were statistically analysed using SPSS Statistics software through linear regression analysis. The results show that a statistically significant model based on cognitive outcomes was able to explain the variance of motor variables. Also, the explanatory value of the model tended to increase with the addition of individual and clinical variables, although the resulting model was not statistically significant The model explained 25-29% of the variability of the Timed Up and Go Test, while for the anteroposterior displacement it was 23-34%, and for the mediolateral displacement it was 24-39%. From the findings, we conclude that the cognitive performance, especially the executive functions, is a predictor of balance deficit in individuals with PD. ARTICLE HISTORY

“…Currently PD diagnosis is based on the presence of at least two of the four cardinal motor features and a good response to levodopa medication (Cooperman, Forwell, & Hugos, 2002;Dirette, 2000;Lim, Van Wegen, de Goede, Jones, Rochester, Hetherington, Nieuwboer, Willems, & Kwakkel, 2005). Melvin Yahr and Margaret Hoehn were the first to develop a system for grading severity of PD (Hoehn & Yahr, 1967).…”

Effect of concurrent walking and interlocutor distance on conversational speech intensity and rate in Parkinson's disease

et al. 2016

This study examined the effects of concurrent walking tasks and interlocutor distance on conversational speech production in fifteen individuals with idiopathic Parkinson's disease (PD) and fourteen age-equivalent controls. Recent studies of speech in PD have demonstrated that changes in the behavioural conditions and the environmental context can have a powerful effect on the severity of speech symptoms in PD. This investigation focused on changes in speech intensity and speech rate in response to changes in walking speed and interlocutor distance. Results suggest that the introduction of a concurrent walking task significantly increased the conversational speech intensity of both controls and individuals with PD. When compared to sitting and talking or standing and talking, current walking and talking appeared to have an energizing effect on conversational speech intensity. In addition, walking faster was associated with a significant increase in conversational speech intensity relative to normal and slow walking speeds. These results provide important new information about the effect of concurrent walking on speech motor performance and speech symptom severity in PD. The potential energizing effect of concurrent walking conditions on conversational speech intensity may be an important consideration in the assessment and treatment of individuals with low speech intensity in PD.

“…The full Movement Disorders Society Unified Parkinson Disease Rating Scale (MDS-UPDRS) was completed [23]. The Berg Balance Scale (BBS) is a well-established tool commonly used to measure balance and has been found to be both reliable and valid [24][25][26]. Interrater and intrarater reliability were measured when testing individuals with PD, the intraclass correlation coefficients were 0.74 and 0.87, respectively [24].…”

The Five Times Sit to Stand test (FTSTS) has been shown to possess discriminative validity in that it was able to discriminate between individuals with and individuals without balance disorders [27].…”

Purpose: Our aims were to: 1) describe participation in people with Parkinson disease (PD), 2) evaluate the relationship between quality of life and participation, and 3) determine which mobility measures predict participation. Methods:Participants with idiopathic PD (n=62) were tested off medication for participation (Activity Card Sort), quality of life (PDQ-39), disease severity (MDS-UPDRS), and mobility (Berg Balance Scale, Five Time Sit to Stand (FTSTS) , Six Minute Walk, forward walking velocity, dual-task walking velocity, andFreezing of Gait Questionnaire (FOGQ)). Relationships of all variables to participation were examined using Pearson correlations. Subsequent regression analysis was employed to determine which mobility measures best predicted participation. Results:Participants with PD retained, on average, 78.3% (SD = 15.6%) of total activities. Participation was negatively correlated with all PDQ-39 domains (r range -.36 to .-78, all p < 0.005) with the mobility domain having the strongest correlation. All mobility measures were significantly correlated with participation, with the final regression model including only FTSTS and FOGQ which combined explained 37% of the variance in participation.Conclusions: Participation is highly related to mobility-related QOL and may be most impacted by ability to stand up from a chair and freezing of gait in those with PD.
