Objective: Examine dynamic stability using Dynamic Postural Stability Index (DPSI) in athletes following anterior cruciate ligament reconstruction (ACLR) at time of release for return-to-sport (RTS), compared to matched controls.
Design: Cross-sectional case-control study.
Setting: Sports medicine clinic.
Subjects: Fifteen ACLR athletes who had completed post-operative rehabilitation and were within 6 weeks following release to RTS were age-, gender-, and activity-matched to 15 healthy controls.
Main Outcome Measures: Ground reaction forces (GRFs) were collected using a portable force plate during stabilization from three different single-leg landing tasks. A composite DPSI was calculated using GRFs.
Results: Compared to matched controls, ACLR athletes within 6 weeks of release for RTS did not significantly differ in dynamic postural stability and there were no significant differences between the involved and uninvolved limbs in the ACLR group.
Conclusion: Current findings indicate that dynamic postural stability, as measured using the DPSI, is not significantly different in ACLR subjects at time of release for RTS compared to matched controls. In addition, the DPSI was not significantly different between the involved and uninvolved limbs in the ACLR subjects. The results suggest that the post-ACLR rehabilitation program utilized may have adequately restored postural stability in this particular sample.

The influence of workload on muscle fatigue, tissue properties, and postural stability in older and younger workers.

Demographic aging and extended working lives have prompted interest in the physiological changes that occur with age, particularly in the lumbar spine. Age-related declines in muscle quality and intervertebral disc alterations may reduce muscular endurance, strength, and postural stability, potentially increasing the risk of musculoskeletal injuries in older workers. As experienced workers play an important role in addressing labor shortages, understanding the impact of age-related physiological changes on the biomechanical properties of the lumbar spine is key to ensure safe and sustainable employment for aging individuals.

Introduction: Galvanic vestibular stimulation (GVS) is a simple, safe, and noninvasive method of neurostimulation that can be used to improve body balance. Several central nervous system diseases cause alterations in body balance, including HTLV-1-associated myelopathy (HAM).
Objective: To test GVS as a balance rehabilitation strategy for HAM.

Background: Falls pose a significant risk to older adults, often leading to severe injury and disability. One potential contributing factor to falls is footwear, particularly shoes with destabilizing features. This systematic review assessed the effects of destabilizing shoes on stability control and fall prevention in older adults, highlighting their effectiveness in balance control and fall prevention, and the detailing the specific review methodology.

Background: For patients undergoing arthroscopic rotator cuff repair surgery (RCR), it is crucial to prevent falls to minimize the risk of re-tearing the repaired muscles. Shoulder immobilization during the postoperative period may lead to a decline in postural balance. This prospective cohort study aimed to investigate the postural balance of patients in the early postoperative period following arthroscopic RCR.

Background: The core is important in providing local strength and balance and is central to almost all kinetic chains of daily activities.
Objective: This study aimed to assess the effectiveness of additional Core Stability Exercises (CSE) to conventional physiotherapy (CP) versus CP alone to improve dynamic sitting balance, coordination, trunk function, and stepping (gait) as a primary outcome and functional sitting balance, postural control, standing balance and fall risk, lower limb spasticity, activities of daily living, degree of disability, and quality of life for early subacute stroke recovery.
Methods: A multicentre parallel, randomized, controlled, assessor-blinded trial was conducted.
