    Background/aim: This study aims at examining the effects of Pilates training on the transversus abdominis (TrA) and internal obliques (IO) muscle thickness and core endurance in different positions in patients with Parkinson's Disease. Materials and methods: Patients were divided into 2 groups as Pilates training (n = 13) and control (n = 10) groups. Pilates training was performed twice a week for 6 weeks. The participants' muscle thickness and core endurance were measured at the beginning of the study (pretraining), and the effectiveness of Pilates training was then assessed in the 6th week (posttraining) and in the 12th-week follow-up. The thickness of the TrA and IO muscles was measured with a two-dimensional ultrasonography device. Core endurance was assessed with prone bridge and sit-ups tests. Results: The assessments of the Pilates training group after the 6-week showed a statistically significant increase in the prone bridge and sit-ups test performances, and an increase in the thickness of the IO muscle [during resting in the supine position and abdominal drawing-in maneuver (ADIM) in standing position] and the TrA muscle (during ADIM in the standing position) (p < 0.05). Pilates exercises were also shown to have improved core muscle endurance and thickness (IO thickness during ADIM in the standing position and TrA thickness during resting in the supine position, ADIM in the supine and standing position) in the Pilates training group after a period of 18 weeks (p < 0.05). Conclusion: Pilates training has a favorable effect on the core endurance, and the TrA and IO muscle thickness of patients with Parkinson's disease and this effect can be maintained until three months after the training.

    The relationship between transversus abdominis and internal oblique thickness and disease-related characteristics in Parkinson's disease: An ultrasound-based study
    (Wolters Kluwer Medknow Publications, 2023) Aktar, Burcin; Ozyurek, Seher; Goz, Evrim; Colakoglu, Berril; Balci, Birgul
    Background and Aim: The core muscles are essential for spinal stability during functional activities. Trunk muscle function is affected by specific neurodegenerative processes of Parkinson's disease (PD). This study aimed to investigate whether changes in transversus abdominis (TrA) and internal oblique (IO) thickness during the abdominal drawing-in maneuver (ADIM) were associated with clinical manifestations, core endurance, and functional mobility in patients with PD. Materials and Methods: We included patients with a modified Hoehn and Yahr staging of 3 or lower. TrA and IO muscle thickness were measured using ultrasound both at rest and during ADIM, and the percent change (%) was calculated to assess TrA and IO activation. Patients performed core endurance (prone bridge and sit-ups) and functional mobility tests (timed up and go [TUG] and five times sit-to-stand [FTSTS]). All assessments were conducted during the on phase. Results: Five female and 17 male patients were included in this study. We found a statistically significant correlation between ultrasound parameters of IO and the clinical manifestations of PD (P < 0.05). Correlations were observed between TrA percent change and prone bridge, sit-ups, TUG, and FTSTS (P < 0.05). Conclusion: To the best of our knowledge, this is the first ultrasound imaging-based study to demonstrate the relationship between TrA and IO muscle thickness and clinical outcomes, and functional performance in patients with PD. Percentage changes in IO were associated with the clinical manifestations of PD. Increased activation of TrA during ADIM was associated with improved core endurance and mobility. The results suggest that a trunk-specific exercise program may be the cornerstone in the treatment of PD-related changes.
