BACKGROUND: Skeletal muscle’s architecture can undergo temporary or permanent adaptations when subjected to chronic passive loading, such as during passive static stretching (PSS). AIM: We evaluated the effects of a 6-week PSS program, with two and five minutes of duration, on the architecture of the Gastrocnemius Medialis (GM) muscle. In addition, we determined the inter-analyzer reliability of the GM’s muscle architecture images analysis process. METHOD: 30 healthy adults participated in this study. Participants were divided into three groups: Control Group (CG), 2-minutes of PSS (G2) and 5-minutes of PSS (G5). Plantar flexors’ PSS was applied three times a week for 6 weeks. Participants were assessed before intervention, after intervention, and two weeks post detraining. GM’s muscle thickness (MT), pennation angle (PA) and fascicle length (FL) were measured with an ultrasound system by an experienced evaluator. All images were analyzed by two independent analyzers, using the Image-J software. RESULTS: No significant effects were identified (p>0.05) of the PSS program on muscle architecture parameters. No architectural changes were observed following the detraining period. GM’s MT results presented excellent reliability, while good reliability was found for the FL measures. For PA, good reliability was only observed for the post-intervention moment. On the pre-intervention and follow-up moments, the intraclass correlation coefficients values were moderate. CONCLUSION: A 6-week PSS program did not generate adaptations on GM’s muscle architecture parameters in healthy subjects, independent of the stretching duration. Muscle architecture parameters are reliable when analyzed by different analyzers following clinical interventions.

BACKGROUND: Evaluating exercise intensity is crucial for designing effective training programs and monitoring progress. The Rating of Perceived Exertion (RPE) scale, a subjective measure of effort, is commonly used for estimating exercise intensity. However, its applicability in specific conditions and populations, particularly in co-contraction training and older individuals, warrants further investigation. AIM: Our main aim was to analyze the correlation between RPE and electromyographic (EMG) activity in co-contraction and conventional resistance training. We also compared muscle activity and RPE across training methods. METHOD: Twenty-three older adults were allocated and divided into conventional resistance training (CRT) and co-contraction training (CCT). EMG activity and RPE were recorded for knee extension and flexion movement and knee co-contraction during training sets and correlated before and after eight weeks of training. RESULTS: The results indicated no significant correlation between EMG activity and RPE for either training method. Additionally, EMG analysis showed higher EMG activity in the CRT than in the CCT. On the other hand, CCT demonstrated an increase in EMG activity after eight weeks of training. CONCLUSION: In conclusion, RPE did not correlate with EMG activity, highlighting the need for finding accessible tools to assess exercise intensity, particularly in older people, and alternative training methods, such as co-contraction training.

BACKGROUND: The acts of reaching and grasping objects are involved in the performance of daily activities. There is a gap in the understanding of how the complexity of the grasping task associated with changes in the base of support influences postural control performance in the older population. AIM: To investigate the postural control performance of older people as they performed the grasping movement, with different levels of task difficulty and complexities of the base of support. METHOD: 15 young and 15 older adults participated. The participants stood on a force platform and performed: 1) Reaching a heavy object; 2) Reaching a light object in rigid and unstable base conditions. The variables analyzed were: area, mean velocity, and mean displacement amplitude of the center of pressure (COP). RESULTS: Older had higher COP velocity in the anteroposterior and mediolateral directions, as well as in the rigid and unstable bases. They also had a larger COP area in the rigid and unstable base of support, and for all gripping tasks. In both groups, the mean amplitude of COP displacement in the rigid base was higher while gripping a heavy object than while gripping a light object or performing a non-gripping task. CONCLUSION: Postural control in the older adults is mainly influenced by the difficulty of grasping tasks. It is possible to identify the postural control performance of the older while they grasp objects during daily activities and to assess how these activities disturb balance, which makes it possible to draw up guidelines to improve postural performance.

BACKGROUND: Poor movement quality of the trunk and the lower limbs as well as dynamic postural control have a strong relation with non-contact injuries in sport. Aiming to reduce the risk of injuries, training approaches using loaded jumps with trunk resistance have been proposed. AIM: To describe how a multiplanar trunk load affects the dynamic postural control and the peak vertical ground reaction force of college athletes with poor movement quality of the trunk and the lower limbs. METHOD: Center of Pressure (COP) variables and peak vertical ground reaction force of 24 female college athletes during single-leg jumps with and without a trunk resistance were compared. RESULTS: There was a significant decrease of the COP displacement (p=0.006), RMS (p=0.009) and velocity (p=0.007) in the anteroposterior direction, and an increase of the COP displacement (p=0.016), RMS (p=0.043) and velocity (p=0.043) in the mediolateral direction, with a moderate effect size. No significant difference was found in the peak vertical ground reaction force. CONCLUSION: Exercises involving multiplanar trunk resistance may negatively impact dynamic postural control in women with poor movement quality.

BACKGROUND: Individuals with Parkinson’s disease (PD) have sensorimotor deficits that affect the mechanisms of postural control. Additional visual information effects on postural control mechanisms in PD were unknown. AIM: To examine the effects of visual information on postural control mechanisms in individuals with PD. METHOD: Seven individuals with PD and five healthy adults (controls) stood, as quiet as possible, on a force plate for 35 seconds with eyes open, eyes closed, or with additional visual feedback [VF] of the center of pressure (COP). The COP trajectories were calculated in anterior-posterior and mediolateral directions and then decomposed to assess two postural control mechanisms: Rambling (i.e., supraspinal) and Trembling (i.e., peripheral). The amplitude and velocity of COP and Rambling and Trembling components were compared between groups for each visual condition. RESULTS: The amplitude and velocity of COP and its components were greater in individuals with PD than controls. They increased under closed eyes condition for PD group, but only the Rambling velocity increased in anterior-posterior direction for controls. When additional VF of the COP was provided, individuals with PD presented increased COP and Trembling velocity in mediolateral direction, while healthy individuals presented reduced sway in both directions. CONCLUSION: Individuals with PD showed greater postural sway and were more affected without visual information than controls. They were not able to use the additional VF to reduce their postural sway as healthy individuals due to changes in sensory integration, causing possible overload in supraspinal processes and compensatory effects in the peripheral postural control mechanisms.

BACKGROUND:Previous studies have demonstrated that people with Parkinson's disease (PD) can acquire postural control skills even with the degeneration of motor areas responsible for consolidation of the representation regarding the learned motor skill in long-term memory. However, these findings have not considered the PD motor subtypes – tremor-dominant (TD), and postural instability and gait difficulty (PIGD). Although there is considerable heterogeneity in motor and non-motor symptoms between TD and PIGD, no study has addressed the effect of the PD subtype on learning postural control skills. AIM:We investigated the influence of PD motor subtypes on the learning of tasks with different postural control demands. METHOD:Fourteen individuals with PD (7 TD, 7 PIGD) practiced four motor tasks with high postural and cognitive demands. Participants completed 13 one-hour sessions (2x/week for 7 weeks). We considered the first and last practice sessions, pre-test and post-test, respectively. Also, we conducted one-week and one-month retention tests to assess performance persistence (motor learning). We assessed motor performance through the scores achieved on each motor task. RESULTS:Both groups demonstrated improvement in performance during the acquisition phase. However, the TD group outperformed the PIGD group in all motor tasks, despite both groups showing improvement in motor performance when comparing the results of pre-test with the post-test, and the improved performance was maintained in retention tests. The performance differences between groups are dissipated during consolidation, and they did not directly affect motor learning. INTERPRETATION: The TD and PIGD motor subtypes learned postural control tasks with different motor and cognitive demands.

BACKGROUND: Five Times Sit to Stand (FTSS) and Timed Up and Go (TUG) are clinical tests in which performance is evaluated through completion time, which can be thought to reflect dynamic balance. Completion time in these tests, however, can be affected not only by balance stability but also by other important components, such as legs’ muscular strength and velocity. AIM: This investigation aimed to evaluate the correlation of completion times in these clinical tests and mediolateral (ML) balance stability measured through lower trunk accelerometry in older individuals. METHOD: Fifteen volunteers were evaluated, aged 60-86 years (M = 69.56±5.89 years). For TUG, we evaluated the conventional version of the test (TUGC), in addition to a dual task (TUGDT) and a new overline (TUGOL) version featured by increased balance demand. Balance stability during test performance was measured through ML accelerations of the lower trunk. RESULTS: The results indicated negative time-acceleration correlations for TUGC (rp = -.71, rp2 =.50, p <.01) and TUGDT (rp = -.77, rp2 =.59, p <.01) and a positive correlation for FTSS (rp =.73, rp2 =.53, p <.01). The TUGOL test failed to show significant time-acceleration correlations. CONCLUSION: Our results suggest that completion time in the FTSS test importantly reflects dynamic balance stability in older individuals. On the other hand, ML trunk acceleration when performing TUG seems to be more related to movement speed than body balance. Our results suggest that completion time can be considered a predictor of dynamic balance in the FTSS test.
背景:FTSS (Five Times Sit to Stand)和TUG (Timed Up and Go)是通过完成时间来评估表现的临床测试，可以认为这反映了动态平衡。然而，在这些测试中，完成时间不仅会受到平衡稳定性的影响，还会受到其他重要因素的影响，比如腿部的肌肉力量和速度。目的:本研究旨在评估这些临床试验完成时间与老年人下躯干加速度计测量的中外侧(ML)平衡稳定性的相关性。方法:15名志愿者，年龄60 ~ 86岁(M = 69.56±5.89岁)。对于TUG，我们评估了传统版本的测试(TUGC)，以及双任务(TUGDT)和新的在线(TUGOL)版本，其特点是增加了平衡需求。通过下躯干的ML加速度来测量测试性能期间的平衡稳定性。结果:TUGC与时间-加速度呈负相关(rp = -)。71、rp2 =。50, p < 0.01)和TUGDT (p = - 0.01)。77、rp2 =。59, p < 0.01)，与FTSS呈正相关(rp =。73、rp2 =。53, p < 0.01)。TUGOL测试没有显示出显著的时间-加速度相关性。结论:我们的研究结果表明，FTSS测试的完成时间重要地反映了老年人的动态平衡稳定性。另一方面，在进行TUG时，ML躯干加速似乎更多地与运动速度有关，而不是身体平衡。我们的研究结果表明，完成时间可以被认为是FTSS测试中动态平衡的预测因子。

BACKGROUND: Different clinical subtypes (i.e., Postural Instability and Gait Difficulty -PIGD and Tremor Dominant -TD) have been highlighted in Parkinson's disease (PD). Although physical exercise improves motor symptoms in PD, the knowledge about the effect of physical exercise considering the PD subtype is limited. AIM: To compare the effects of long-term locomotion and balance exercise on lower limb functional strength and functional mobility in PD subtypes. METHOD: Eight individuals PIGD and 10 TD participated in this study. All individuals participated in the interventions with exercises focused on improving locomotion and balance. 48 sessions of exercise were performed three times per week for 60 minutes each session. Functional Mobility was analyzed by the Timed Up and Go test (TUG) in a single (ST) and double-task (DT – i.e., subtraction by three). Lower limb functional strength was analyzed by the 30s sit-to-stand test. Both tests were performed at baseline (pre-test) and post-intervention (post-test). Statistical analysis was performed by two-way ANOVA, with Group (PIGD vs. TD) and Moment (pre vs. post-test) factors, with repeated measures for the second factor. RESULTS: PIGD decreased the time to perform TUG_ST in the post-test compared to the pre-test (p=0.001). Both groups decreased the time in TUG_DT and increased the number of repetitions in sit-to-stand test in the post-test in relation to the pre-test (p<0.05). CONCLUSION: Long-term locomotion and balance exercise programs can improve functional mobility mainly in PIGD. A possible explanation is due to the greater room for improvement of PIGD subtypes and exercise specificity.
背景:不同的临床亚型(即姿势不稳定和步态困难-PIGD和震颤显性-TD)在帕金森病(PD)中得到了强调。虽然体育锻炼可以改善PD患者的运动症状，但考虑到PD亚型，关于体育锻炼效果的知识有限。目的:比较长期运动和平衡运动对PD亚型患者下肢功能力量和功能活动能力的影响。方法:8例PIGD患者和10例TD患者参与了本研究。所有人都参与了以改善运动和平衡为重点的干预运动。每周三次，每次60分钟，共进行48次锻炼。在单任务(ST)和双任务(DT -即减3)中，通过Timed Up and Go测试(TUG)分析功能迁移能力。采用30s坐立试验分析下肢功能强度。两项测试均在基线(测试前)和干预后(测试后)进行。统计分析采用双因素方差分析，组(PIGD vs. TD)和时刻(测试前vs.测试后)因素，第二个因素重复测量。结果:与前测相比，PIGD减少了后测中进行TUG_ST的时间(p=0.001)。与前测相比，两组在测试后均缩短了TUG_DT时间，增加了坐立测试的重复次数(p<0.05)。结论:长期运动和平衡训练方案主要能改善PIGD患者的功能活动能力。一种可能的解释是由于PIGD亚型和运动特异性有更大的改进空间。

BACKGROUND: Gait and balance deficiencies are significant concerns for people with multiple sclerosis, resulting in reduced walking capacity, falls and poor quality of life. Issues caused by sensory loss and the inability to properly reweight sensory information are often reported. Even at the early stages of the disease, subclinical gait and balance impairments can be found. AIM: In this article, we review objective measures used to assess gait and postural balance impairment in multiple sclerosis patients. INTERPRETATION: Although scales and clinical tests are important tools for assessing postural instability and walking performance, they can be insensitive to minor disabilities in multiple sclerosis. Instrumented measurements, such as kinematics, kinetics, spatiotemporal gait parameters and center of pressure, play an important role in detecting impairment and evaluating the effects of interventions in people with mild to moderate multiple sclerosis. Thus, objective measurements may be more suitable for tracking deficits in gait and postural balance in multiple sclerosis, contributing to the early detection of disease symptoms, and therefore allowing for the planning of effective interventions to control the speed of disease progression.
