Background: Pilates-based core stability training (PBCST) is a controlled form of exercise that may improve the transmission of torque from the upper extremities and trunk to the lower extremities by enabling the core muscles to activate effectively. Objectives: The aim of this study was to investigate the effects of PBCST given as supervised or home-based on lower extremity strength and postural control in multiple sclerosis. Methods: Fifty individuals were enrolled and randomly allocated into two groups. Primary outcome measures were knee muscle strength and postural sway in different conditions. The supervised group received PBCST 2 days per week for 8 weeks at the clinic, and the other group performed PBCST at home. Exercises were progressed every 2 weeks in both groups. Results: Between groups, the supervised group was mostly superior to the home group ( p < 0.05). A significant improvement was noted in all parameters in both groups, except some sub-parameters of postural sway in home PBCST ( p < 0.05). Conclusions: Supervised PBCST was determined to be more effective than home PBCST in improving strength, postural control, core stability, physical capacity, and fatigue. Although supervised training is the primary choice, home training can be recommended to patients who have limitations attending supervised sessions.

Abstract Background Fall prevention in older adults is an important task. Lower extremity function is a main focus in fall prevention. There are few previous studies focusing on core stability. The purpose of this study was to investigate the relationship between fall risk and core stability. Methods The study participants were 33 community-dwelling older adults (mean age: 65±17 years old; 5 men, 28 women). The fall risk was assessed using the Fall Risk Index-21 (FRI-21). Core stability measured the retention time of Side Bridge (SB) and Front Bridge (FB). Secondary outcome measures included lower extremity muscle strength (knee extension, hip abduction) and physical function (two-step test). Statistical analysis investigated the correlation between the measurement items. Results We found a significant negative correlation between FRI-21 and SB (r = -0.51, p&lt;0.01) and FRI-21 and FB (r = -0.47, p&lt;0.01). We also found a correlation between FRI-21 and the two-step test (r = -0.40, p&lt;0.05). There was no significant correlation between FRI-21 and lower extremity muscle strength. Discussion FRI and Core stability showed moderate correlation. It suggests that the core and hip muscle functions involved in posture retention are involved with fall. Conclusion The risk of falls in older adults was related to core stability. If the core stability of older adults improves, it may help to reduce the risk of falling. Therefore, it is useful to consider core stability in the assessment of fall risk.

Abstract Background The effects of group exercise on the physical function of community-dwelling older adults remain unclear. The changes in lower extremity muscle strength, timed up and go (TUG) time, and the motor fitness scale (MFS), over time, among older adults who expressed a willingness to participate in community-based physical exercise groups, were determined using multilevel modelling. Methods We analyzed data of 2407 older adults between April 2010 and December 2019 from the registry of physical tests of community-based physical exercise groups. We conducted a retrospective cohort study to assess the effect of physical exercise on lower extremity muscle strength, TUG time, and MFS scores. The durations of the exercises were evaluated by frequency of physical test’s participate. Results A deterioration in lower extremity muscle strength was found in the short-term participant group only. However, in the mid-term and long-term participation groups, lower extremity muscle strength showed a trend of improvement. The TUG time and the MFS score were negatively correlated with increasing age in both groups divided by the duration of participation. However, there was a slower rate of deterioration in the long-term participation group. Discussion Lower extremity muscle strength, TUG time, and MFS scores decline with increasing age and there were differences in the slope of deterioration that depended on the duration of participation in community-based group exercise. Conclusion Participation in group exercise improved lower extremity muscle strength, TUG time, and MFS scores of older adults living in a community. The positive effects of group exercise were dependent on long-term participation.

Abstract Background The risk of adverse events associated with peritoneal dialysis (PD) in elderly patients has not been thoroughly investigated. The purpose of this study was to assess the association between physical function and hospitalization in elderly PD patients. Methods This is a single-center prospective observational cohort study. Thirty-three aged patients (74.8 ± 5.9 years) participated in a 6-min walk distance, short physical performance battery (SPPB), lower extremity muscle strength, and 10-m walk speed. All subjects were followed until hospitalization to the end of the follow-up period. Results The 6-min walk distance was 332 ± 112.5 m; SPPB was 11 (8.3–12) points; the lower extremity muscle strength was 36.6 ± 9.6%; 10-m walk speed was 1.1± 0.2 m/s. During the follow-up, 19 patients (57.5%) were hospitalized. In the Kaplan-Meier survival analysis and log-rank test, a lower 6-min walk distance and PD vintage were significantly associated with hospitalization (p<0.05). After adjustment for PD vintage in Cox proportional analysis, the 6-min walk distance remained associated with hospitalization (95% confidence interval, 0.98–0.99). Conclusion Lower exercise tolerance assessed by the 6-min walk distance was significantly associated with hospitalization in elderly PD patients. Our findings indicate that measurement and intervention of exercise intolerance are essential to predict the clinical outcomes of elderly PD patients. Trial registration This study was prospectively registered at inception in the UMIN Clinical Trials Registry under identification number UMIN000038405.

Background: Occupational footwear and a prolonged duration of walking have been previously reported to play a role in maintaining postural stability. The purpose of this paper was to analyze the impact of three types of occupational footwear: the steel-toed work boot (ST), the tactical work boot (TB), and the low-top work shoe (LT) on previously unreported lower extremity muscle activity during postural stability tasks. Methods: Electromyography (EMG) muscle activity was measured from four lower extremity muscles (vastus medialis (VM), medial hamstrings (MH), tibialis anterior (TA), and medial gastrocnemius (MG) during maximal voluntary isometric contractions (MVIC) and during a sensory organization test (SOT) every 30 min over a 4 h simulated workload while wearing ST, TB, and LT footwear. The mean MVIC and the mean and percentage MVIC during each SOT condition from each muscle was analyzed individually using a repeated measures ANOVA at an alpha level of 0.05. Results: Significant differences (p < 0.05) were found for maximal exertions, but this was limited to only the time main effect. No significant differences existed for EMG measures during the SOT. Conclusion: The findings suggest that occupational footwear type does not influence lower extremity muscle activity during both MVIC and SOT. Significantly lower muscle activity during maximal exertions over the course of the 4 h workload was evident, which can be attributed to localized muscular fatigue, but this was not sufficient to impact muscle activity during postural stability tasks.

Extremity Injuries

Ankle injuries are common among young ballet dancers. These injuries may be attributed to ankle instability, insufficient lower extremity strength, and poor balance control. The purpose of this study was to explore whether these dancers exhibit functional ankle instability and if their single-leg balance control and lower extremity muscle strength correlate with functional ankle instability and leg injuries. Twenty-one ballet dancers (aged 10 to 17 years) participated in the study. The Cumberland Ankle Instability Tool (CAIT) questionnaire was used to examine functional ankle stability. Isometric muscle strength of the major lower extremity muscles was measured with a digital hand-held dynamometer. Single-leg balance was evaluated with the Y-Balance Test (YBT) and three Athletic Single-leg Stability Test (ASLST) protocols. Lower extremity injuries (self-reported) within 6 months after testing were recorded for correlation analyses. Both dominant and non-dominant ankles of the subjects exhibited functional ankle instability (26.71 and 25.71, respectively). Raising the center of mass (passé and first arm position) during the ASLST did not significantly affect balance performance (p = 0.104). However, removing extrinsic visual feedback significantly decreased single-leg balance (p < 0.001). In general, there was low correlation (r ≤ 0.49) between muscle strength, CAIT, YBT, and ASLST scores with lower extremity injuries. It is concluded that for young ballet dancers lower extremity muscle strength and single-leg balance control may not be strong contributing factors to leg injuries. This study also suggests that functional ankle stability may not have a direct impact on single-leg balance, and ballet dancers rely heavily on extrinsic visual feedback for single-leg balance control. Teachers might consider minimizing extrinsic feedback to challenge ballet dancers when implementing training protocols for single-leg balance control.
