PURPOSE/BACKGROUND: Shoulder proprioception is essential in the activities of daily living as well as in sports. Acute muscle fatigue is believed to cause a deterioration of proprioception, increasing the risk of injury. The purpose of this study was to evaluate if fatigue of the shoulder external rotators during eccentric versus concentric activity affects shoulder joint proprioception as determined by active reproduction of position. STUDY DESIGN: Quasi-experimental trial...

The coracoacromial ligament (CAL) was first described as a pain generator by Dr Charles Neer in the early 1970s. Since that time, considerable controversy regarding CAL management during acromioplasty has persisted. This review aims to better understand the role of the CAL in shoulder physiology and pathology. Sixty-six articles from 1958 to 2016 were identified using an electronic search of PubMed, Cochrane Library, AccessMedicine, and MD Consult for case series as well as cohort and prospective studies. The authors used "coracoacromial ligament" and "coracoacromial veil" as medical subject headings (MeSH)...

Neuropathic osteoarthropathy, which is known as Charcot osteoarthropathy, is a degenerative arthritis that develops as a result of proprioceptive and sensory innervation loss. A 47-year-old man was admitted to the emergency department of the hospital with left shoulder pain, which was ongoing and exacerbating for 5 days. Examination of the cervical region takes a crucial part in determining shoulder pathology. Palliative therapy is the prior treatment of choice as surgical therapy has potential risks in Charcot osteoarthropathy...

BACKGROUND: Functional evaluation of sensorimotor function of the shoulder joint is important for guidance of sports-specific training, prevention and rehabilitation of shoulder instability. Such assessment should be multimodal and comprise all qualities of sensorimotor shoulder function. This study evaluates feasibility of such multimodal assessment of glenohumeral sensorimotor function in patients with shoulder instability and handball players. METHODS: Nine patients with untreated anterior instability of their dominant shoulder and 15 asymptomatic recreational handball players performed proprioceptive joint position sense and dynamic stabilisation evaluations on an isokinetic device, as well as a functional throwing performance task...

S Contemori, A Biscarini
Isolated infraspinatus atrophy (IIA) is a common condition among overhead-activity athletes, which affects the hitting shoulder and is caused by suprascapular nerve injury. As the suprascapular nerve is a mixed nerve, such damage could lead to reduced afferent proprioceptive information and impaired shoulder sensorimotor control. This study aimed to evaluate the proprioception of the shoulder with IIA, through the assessment of shoulder position sense. The shoulder position sense was assessed in 24 professional volleyball players (12 players with IIA and 12 healthy players) with a blind dynamic shoulder repositioning test (all participants were blindfolded during the test)...

Previous research suggests integration of visual and somatosensory inputs is enhanced within reaching (peripersonal) space. In such experiments, somatosensory inputs are presented on the body while visual inputs are moved relatively closer to, or further from the body. It is unclear, therefore, whether enhanced integration in "peripersonal space" is truly due to proximity of visual inputs to the body space, or, simply the distance between the inputs (which also affects integration). Using a modified induction of the rubber hand illusion, here we measured proprioceptive drift as an index of visuosomatosensory integration when distance between the two inputs was constrained, and absolute distance from the body was varied...

The motor rehabilitation is based on exercises that involve various joints and muscle groups. One such treatment method is Proprioceptive Neuromuscular Facilitation (PNF), which involves diagonal movements simulating many activities of daily living. The objective of this study was to investigate the differences between PNF and shoulder flexion movements performed without the diagonal component (i.e., only in the sagittal plane) using beta band absolute power as a measure of plasticity. The study included 30 volunteers randomized into three groups (control, PNF, and FLEX), with electroencephalographic signals captured before and after the performance of the task...

When an electrical stimulus is applied to perturb the vestibular system, a postural response is generated orthogonal to head orientation. It has previously been shown that there is a convergence of neck proprioceptive and vestibular input within the cerebellum to provide a head-on-body reference frame (Manzoni et al. in Neuroscience 93:1095-1107, 1999). The objective of this experiment was to determine whether the direction of the postural response to a vestibular perturbation is modulated when function of the cerebellar vermis is temporarily depressed...

Traditionally, proprioception has been assessed with a passive model, in which an external apparatus moves a body segment. Recently, protocols have been developed based on active movements, which are more representative of functional activities. However, even these approaches require expensive testing equipment and the necessity of a visit to a research lab, as there are no commercially available mobile instruments that allow for the assessment of proprioception outside of a laboratory setting. The objective of this study was to demonstrate the validity and feasibility of using a mobile device (iPod Touch) to assess joint position...

Proprioception is essential for shoulder neuromuscular control and shoulder stability. Exercise of the rotator cuff and scapulothoracic muscles is an important part of shoulder rehabilitation. The purpose of this study was to investigate the effect of rotator cuff and scapulothoracic muscle exercises on shoulder joint position sense. Thirty-six healthy subjects were recruited and randomly assigned into either a control or training group. The subjects in the training group received closed-chain and open-chain exercises focusing on rotator cuff and scapulothoracic muscles for four weeks...

Tomohiro Amemiya, Hiroaki Gomi
Active touch sensing is known to facilitate the discrimination or recognition of the spatial properties of an object from the movement of tactile sensors on the skin and by integrating proprioceptive feedback about hand positions or motor commands related to ongoing hand movements. On the other hand, several studies have reported that tactile processing is suppressed by hand movement. Thus, it is unclear whether or not the active exploration of force direction by using hand or arm movement improves the perception of the force direction...
