Obstructive sleep apnea (OSA) is the most prevalent sleep disorder caused by breathing difficulties, characterized by repeated episodes of airway blockage while sleeping. Various interventions have been used to improve the symptoms and overall health of individuals with OSA. However, few studies have focused on the impact of exercise on OSA.

Recent findings suggest that most sports-related injuries occur during the latter stages of these activities, often due to fatigue, which can impair proprioception and increase the risk of injury. Proprioception can be divided into three categories: joint position sense, the sense of movement (kinesthesia), and the sense of force reproduction. While several studies have examined how exercise-induced fatigue affects various aspects of proprioception on lower limb joints, research focusing on the shoulder joint is limited.

Background: The last phases of a competitive game are when shoulder injuries most commonly happen, and fatigue is thought to be a major contributing factor, perhaps because of reduced proprioception and motor control. The purpose of this study was to investigate the effect of concentric fatigue on proprioception, motor control, and performance of the upper limb in handball players.

Methods: Forty-six right-handed handball players (all males, age 26.

Objectives: To investigate the effect of concentric fatigue on proprioception, motor control and performance of the shoulder in healthy young adults.

Design: Test-retest experimental design.

Setting: Human performance laboratory.

Article Synopsis
  • Joint position sense (JPS) is crucial for knee function, but the impact of muscle pain on JPS hasn't been previously explored.
  • Researchers injected hypertonic saline to induce muscle pain in 26 physically active adults and assessed their knee JPS through repositioning tasks at angles of 15°, 45°, and 60°.
  • Results showed that absolute angular errors increased significantly at 15° and 45° after pain induction, while variability of knee repositioning decreased at 15° and 60°, suggesting pain impairs proprioceptive accuracy in healthy individuals.
  • Further studies are needed to see if similar effects occur in individuals with existing knee pain.

Objectives: Deficits in proprioception and postural control are common in patients with different musculoskeletal pain syndromes. It has been proposed that pain can negatively affect proprioception and postural control at a peripheral level, however research is limited to animal studies. Human studies have shown that it is more likely, that the link between pain and proprioceptive deficits, lies within changes in the central nervous system where noxious and non-noxious stimuli may overlap.

Spinal radiculopathy (SR) is a multifactorial nerve root injury that can result in significant pain, psychological stress and disability. It can occur at any level of the spinal column with the highest percentage in the lumbar spine. Amongst the various interventions that have been suggested, neural mobilization (NM) has been advocated as an effective treatment option.
