The effects of the use of reduced feedback frequencies on motor learning remain controversial in the scientific literature. At present, there is still controversy about the guidance hypothesis, with some works supporting it and others contradicting it. To shed light on this topic, an experiment was conducted with four groups, each with different feedback frequencies (0%, 33%, 67%, and 100%), which were evaluated three times (pre-test, post-test, and retention) during a postural control task. In addition, we tested whether there was a transfer in performance to another similar task involving postural control. As a result, only the 67% feedback group showed an improvement in their task performance in the post-test and retention evaluations. Nevertheless, neither group showed differences in motor transfer performance compared to another postural control task. In conclusion, the findings of this paper corroborate the hypothesis of guidance and suggest that the use of a reduced frequency of 67% is a better option for improving motor learning than options that offer feedback at a lower frequency, at all trials or not at all.

Study Design: Prospective cohort study.
Objective: This study aimed to investigate the durability of postural stability after ASD correction surgery and its' association with clinical outcomes.
Summary Of Background Data: The prevalence of symptomatic adult spinal deformity (ASD) necessitates surgical intervention, aiming to correct global spinal balance and spinopelvic parameters.

Study Design: A randomized controlled trial using a pretest-posttest control group design.
Purpose: This study investigated the effects of core stabilization exercises (CSEs) on cervical sagittal vertical alignment (cSVA), Cobb's angle, and Neck Disability Index (NDI) scores in patients with forward head posture (FHP).
Overview Of Literature: FHP is a local poor neck posture.

Many individuals with incomplete spinal cord injury (SCI) exhibit reduced volitional control of trunk muscles, such as impaired voluntary contractions of the erector spinae (ES), due to damage to the neural pathways regulating sensorimotor function. Studies using conventional bipolar electromyography (EMG) showed alterations in the overall, or global, activation of the trunk muscles in people with SCI. However, how activation varied across specific regions within the ES, referred to as regional activation, remains unknown.

Background: Aquatic training is known for its effective and gentle rehabilitation benefits, but its impact on athletes with chronic ankle instability (CAI) remains underexplored. This study compares the effects of water-based and land-based balance training on functional performance, dynamic balance, fear of reinjury, and quality of life in athletes with CAI.
Methods: Forty-one athletes with chronic ankle instability (CAI) were randomly assigned to water-based (WBBE, n = 21) or land-based (LBBE, n = 20) balance exercise groups, completing 24 sessions of 30-45 min over 8 weeks.

Background: Ankle joint position sense (AJPS) accuracy and postural control are crucial for maintaining balance and stability, particularly in individuals with plantar fasciitis who may experience proprioceptive and functional impairments. Understanding how psychosocial factors, such as pain catastrophizing, and biomechanical measures, like muscle strength and gait parameters related to proprioception and postural control, can inform more effective treatment approaches. This study aimed to (1) examine the relationship between AJPS accuracy and biomechanical factors-including postural stability, lower limb muscle strength, and gait parameters-in individuals with plantar fasciitis d (2) analyze the impact of psychosocial factors, including pain catastrophizing, physical activity level, and quality of life, on AJPS accuracy and postural control in this population.
