“…Both TUG and iTUG require cognitive and motor functions for their realizations and both have been correlated with these functions in previous studies [9][10][11]14] . TUG combines the 4 phases of sit-to-stand movement, initiation, acceleration and deceleration of gait, preparation of turning, turning and finally turning around to sit down [11] .…”

“…The iTUG involves an approach based on motor imagery, widely used by athletes to improve performance as well as in the rehabilitation for neurological diseases [15][16][17][18] . In schizophrenia, impaired TUG and iTUG were explained by alterations in executive function performances [10] . In relapsing-remitting multiple sclerosis, TUG was correlated with memory, attention and also with executive functions [11] .…”

“…However, to date, it has never been applied to explore gait abnormalities and disability in ALS. To study motor imagery of gait and balance, an imagined TUG (iTUG) has been validated in healthy older adults and in patients with neuropsychiatric conditions, and has been also associated with cognitive decline [9][10][11] . We hypothesized that both the TUG and iTUG are achievable in ALS patients and that they correlate with functional motor disability.…”

Objective: Gait and balance are key determinants of disease status in amyotrophic lateral sclerosis (ALS). This study aims at testing the relationship between the imagery of gait and disability in patients with ALS. Methods: Twenty-five consecutive patients (63.8 ± 2.4 years; 52% female) performed the timed up and go (TUG) test and a validated imagined version of the TUG between March 2011 and May 2012. The revised ALS functional rating score (ALSFRS-R) was assessed simultaneously. Results: The mean duration of TUG (16.7 ± 2.2 s) was significantly longer than imagined TUG (iTUG; 10.5 ± 1.4 s, p < 0.001). The TUG (R² = 0.40, p = 0.001) and the iTUG (R² = 0.30, p = 0.007) were significantly associated with results of the ALSFRS-R score (37.0 ± 7.3) as well as with muscle strength in arms (TUG R² = 0.42, p < 0.001, iTUG R² = 0.38, p = 0.001) and legs (TUG R² = 0.47, p < 0.001, iTUG R² = 0.46, p < 0.001). TUG and iTUG increased with age (TUG R² = 0.18, p = 0.04, iTUG R² = 0.12, p = 0.05). Conclusion: ALS patients performed the imagined gait faster than the real gait. Both TUG and iTUG correlated with disability measured by the ALSFRS-R score and by muscle strength. These inexpensive and easy clinical tests represent promising tools in clinical practice to study gait in ALS.

“…Second, after adjusting for covariates (including age), Donoghue et al (2012) also reported significant associations between TGUG time and speed of processing. Furthermore, although there is a lack of research on the association of mobility and cognition in older adults with schizophrenia, a small (n=17) study in patients with early schizophrenia (mean age 30) showed a significant univariate association between TGUG time with cognitive function (measured with the MMSE and a Frontal Assessment Battery) (Lallart et al, 2012). …”

“…Only three studies(Chwastiak et al, 2006; Lallart, Jouvent, Herrmann, Beauchet, & Allali, 2012; Viertio et al, 2009) have explored the relationship between schizophrenia symptoms, neurocognitive functioning and/or mobility in people with schizophrenia. The previous studies suggest more severe symptoms and impaired neurocognition negatively impact aspects of physical mobility.…”
