Adherence to 8 weeks of square-step exercise training by Parkinson’s disease patients significantly improved cognitive as well as executive function in patients with mild cognitive impairment.
popularity and notoriety exercise In the elderly, SSE involves multidirectional steps that can become increasingly difficult and complex, in which attention, memory, and executive function all play important roles.
The additional positive effects of exercise programs on lower extremity muscle strength, balance, flexibility, and cognitive function in older adults have been shown by researchers to be particularly useful for PD patients affected by executive dysfunction, even in the early stages. One thing was noticed. illness.
“As the disease progresses, many PD patients present with mild cognitive impairment (MCI). Cognitive decline can further lead to loss of independence and poor quality of life in PD patients. , this issue needs serious consideration,” they said.
“SSE appears to be a promising intervention for improving executive function in PD patients. However, the evidence supporting the benefits of SSE in PD is still lacking.”
The study authors conducted a single-blind, randomized, controlled pilot study in 28 PD patients recruited from Mackay Memorial Hospital between March 2018 and August 2020 to assess the effects on executive function. We investigated the impact of SSE. A subgroup analysis was also performed to assess the impact of SSE on executive function in PD patients with MCI.
Participants were randomly assigned to an experimental group (n = 14), which received the SSE program twice weekly for eight weeks, or a control group (n = 14), which received conventional treatment at the same rate.
The primary outcomes of the trail-making test and finger-span task and the secondary outcomes of measured global cognition and quality of life were assessed by the pre- and post-intervention Montreal Cognitive Assessment and the Chinese translation of the 39-item PD questionnaire, respectively. it was done. , and at a 1-month follow-up.
During the intervention period, most participants completed 16 exercise sessions, demonstrating full participation in each session, with the exception of dropouts in the control group. Five participants did not complete the follow-up assessment (3 in the experimental group and 2 in the control group).
When assessing within-group differences at three time points, time effects were shown only in the experimental group, and significant improvements in executive function were observed anteriorly in the finger-span task (P. = .004) and reverse the digit span task (P. = .002). A near-significant improvement trend was also seen in part A of the trail-making test (P. = .069) after SSE training.
Post-hoc analysis findings further showed significant improvement in the assessed outcomes compared to pre-intervention in the experimental group.P. = .002), and the score of the post-intervention number span task (P. = .013) and at 1-month follow-up (P. = .004) was higher than before intervention.
For secondary outcomes, a trend toward significance was observed in the Montreal cognitive assessment (P. = .064) and scores improved significantly at 1-month follow-up (P. = .012). No significant improvement was observed on the 39-item PD questionnaire after intervention in both groups.
Furthermore, subgroup analyzes showed that the forward finger-span task, backward finger-span task, and Montreal cognitive assessment in PD patients with MCI were significantly improved after intervention in the experimental group.
“Overall, the results of this study indicate that SSE may be recommended as a treatment to reduce the cognitive impact of PD,” the researchers concluded.
