“…The ED group was 51.4% and had significantly lower TMT part A, MMSE, and FIM cognitive part scores than the NED group. Our results are consistent with those of previous studies (S. Hayes et al., 2016; Sakai et al., 2023). For the prevalence, it was reported that the percentage of patients in stroke with ED was 47%, and the percentage reported for the current study was 51.4%.…”

“…In addition, Sakai et al. (2023) investigated whether the 10‐m walking time differs according to the degree of executive dysfunction in patients with stroke. They found that the degree of executive dysfunction was associated with 10‐m walking time, with more severe executive dysfunction leading to longer walk times in patients with stroke.…”

IntroductionA previous study has shown an association between executive dysfunction (ED) and balance function in patients with stroke. However, it is unclear what factors mediate the association between ED and balance function. Therefore, the aim of this study was to investigate the association between ED and balance function and to identify mediating factors using mediation analysis.MethodsThis study had a cross‐sectional design. The study included 107 patients with stroke. This study was divided into two groups (ED and non‐ED) using trail making test (TMT) part B. Two groups were compared for balance function (timed up and go test [TUGT] and Berg balance scale [BBS]) and other variables using paired test. In addition, partial correlation analysis with age, cognitive function as a control factor, and mediation analysis were also performed.ResultsThe ED group (N = 55) had significantly lower TUGT and BBS scores than the non‐ED group (N = 52). TMT part B correlated with TUGT (ρ = 0.41), BBS (ρ = −0.33), and Brunnstrom recovery stage (BRS) lower limb (ρ = −0.22). The TUGT model of mediation analysis showed a significant indirect effect as a result of mediation of the BRS lower limb between TMT part B and TUGT. The BBS model showed a significant indirect effect as a result of mediation of the activities of daily living (ADL) motor function between TMT part B and BBS.ConclusionsED and balance function were associated, and the degree of paralysis and ADL motor function were associated with them in patients with stroke.

“…In the literature, TUG and BERG tests [14,[24][25][26] for balance assessment in hemiplegia patients, MAS scoring [27] for spasticity assessment, MMSE [28] for mental status, and RMI [29] for functional status are frequently used. To determine the efficacy of the treatments, the parameters were evaluated with pre-test and posttests.…”

Objective It was planned to investigate the effects of proprioceptive exercises applied to patients with hemiplegia on muscle tone, balance, perception, posture, mobility, and spatiotemporal parameters. Materials and Methods 70 participants with hemiplegia were randomized to an experimental group (conventional stroke rehabilitation program+proprioceptive exercise, 30 sessions) and a control group (conventional stroke rehabilitation program, 30 sessions). Timed Up and Go (TUG) Test, Modified Ashworth Scale (MAS), Posture Assessment Scale for Stroke Patients (PASS), Mini-Mental State Examination (MMSE), Rivermead Mobility Index (RMI), Spatiotemporal parameters (cadence, maximum plantar pressure, total weight transfer, step cycle duration, swing phase, step length and foot angle), and Berg Balance Scale (BERG) were applied on all participants before and after treatment. Results When the intra-group values were compared before and after the treatment, TUG, PASS, MMSE, RMI and BERG values increased significantly. MAS upper extremity and MAS lower extremity values decreased significantly. (p<0.01). In the comparison between the groups, one of the spatiotemporal parameters, cadence, total weight transfer, and maximum plantar pressure values, increased significantly after the treatment. Step cycle duration, swing phase, step length and foot angle values decreased significantly after the treatment. (p<0.01) Conclusion Unlike the literature, proprioceptive exercises that we add to the conventional rehabilitation program can be used to improve muscle tone, balance, perception, postural control, mobility, and spatiotemporal parameters.

“…VMI elicits motor imagery by creating an illusion from visual stimuli, similar to the AOT task. Sakai et al [ 30 ] also reported that motor imagery ability was related to lower limb function in patients with hemiplegia. Thus, the degree of improvement in motor function may be related to lower-extremity function with VMI.…”

Visual-motor illusion (VMI) is an intervention to induce kinesthetic sensation from visual stimuli. We aimed to compare the effects of VMI of different visual stimuli on the paralyzed side ankle joint of stroke hemiplegic patients (hemiplegic patients) and to clarify their indication. We applied two types of VMI images of ankle dorsiflexion: ankle dorsiflexion without resistance (standard VMI (S-VMI)) and maximum effort dorsiflexion with resistance (power VMI (P-VMI)). Twenty-two hemiplegic patients were divided into two groups: Group A, which received S-VMI first and P-VMI one week later (n = 11), and Group B, which received P-VMI first and S-VMI one week later (n = 11). Immediate effects were evaluated. Outcomes were the dorsiflexion angle and angular velocity, degree of sense of agency (SoA), and sense of ownership. Patient’s characteristics of cognitive flexibility were assessed using the Trail making test-B (TMT-B). Fugl-Meyer assessment and the Composite-Spasticity-Scale were also assessed. P-VMI was significantly higher than S-VMI in SoA and dorsiflexion angular velocity. Additionally, the degree of improvement in dorsiflexion function with P-VMI was related to TMT-B and degree of muscle tone. Therefore, P-VMI improves ankle function in hemiplegic patients more than S-VMI but should be performed with cognitive flexibility and degree of muscle tone in mind.
