“…During normal gait, the hip extensor muscle engages in the initial phase of the stance, inducing a posterior pelvic tilt. Decreased strength in this muscle among individuals with PD might contribute to an exaggerated anterior pelvic tilt and forward trunk flexion [ 14 ]. Such abnormal posture could lead to instability in balance and increase the risk of falls.…”

Background. Postural instability and gait difficulties (PIGD) are a significant cause of falls, mobility loss, and lower quality of life in Parkinson’s disease (PD). The connection between PD progression and diminished strength in the lower limbs has been acknowledged. However, the identification of specific muscle groups linked to PIGD and non‐PIGD motor features is still unknown. Objective. To explore the relationship between the strength of specific lower limb muscle groups, along with muscle mass, and their associations with PIGD, PIGD subtypes, and non‐PIGD motor features in PD. Methods. 95 PD participants underwent detailed motor and non‐motor test batteries, including lower limb isometric strength testing and whole‐body lean mass assessments. Correlation analysis and univariate and multivariate linear/logistic forward stepwise regression were performed to test associations between PIGD and non‐PIGD motor features with normalized value (z‐score) of lower limb muscle strength and measures of lean mass. Results. Multivariate regression analysis, adjusted for age, gender, and levodopa equivalent dose, revealed that hip abductor strength was significantly associated with overall PIGD motor severity ratings (p < 0.001), impaired balance (p < 0.001), and non‐PIGD Parkinsonian motor features (p < 0.001). Conversely, hip extensor strength was significantly associated with falls, slow walking, and FoG motor features (p = 0.016; p = 0.003; p = 0.020, respectively). Conclusion. We found that lower hip abductor strength was associated with PIGD and non‐PIGD motor features. The association between non‐PIGD motor features may suggest specific vulnerability of the hip abductors as part of a proposed brain‐muscle loop hypothesis in PD. Moreover, lower hip extensor strength correlated with falls, slow walking, and FoG.

“…In a study examining the relationship between the thickness of the trunk muscles such as erector spinae and multifidus and the sagittal spinal alignment in PD, it was reported that there is a correlation between the decrease in the thickness of the trunk muscles and the decrease in the lumbar lordosis. In addition, it was emphasized that it is important to seek effective strength training methods to improve the thickness of the trunk muscles in patients with PD [ 16 ].…”

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.
