Impairment of joint proprioception in patients with hypermobility syndrome (HMS) has been well documented. Both joint proprioception and muscle torque are commonly assessed in patients with musculoskeletal complaints. It is unknown, however, if these measures change significantly on repeated application in healthy children and in children with HMS. AIM: To investigate the between-days repeatability of joint proprioception and muscle torque in these groups. Twenty children (10 healthy and 10 with HMS), aged eight to 15 years, were assessed on two separate occasions (one week apart) for joint kinaesthesia (JK), joint position sense (JPS), and the extensor and knee flexor muscle torque of the knee. JK was measured using threshold to detection of passive movement. JPS was measured using the absolute angular error (AAE; the absolute difference between the target and perceived angles). Knee extensor and flexor muscle torque was normalized to body weight. ...

Proprioception is a sensory modality that provides feedback on the internal status of the body and enables us to perceive joint position and motion.. Osteoarthritis (OA), also called degenerative joint disease, is a major musculoskeletal condition characterized by loss of articular cartilage that leads to pain and loss of function. The most commonly affected joint is the knee, and OA may result in changes that affect not only intracapsular tissues, but also periarticular tissues, such as ligaments, capsules, tendons, and muscles. Many studies have examined the proprioceptive status of knee OA, and subjects with knee OA are known to have impaired proprioception compared with age-matched controls.. Joint effusion is a common symptom associated with chronic degenerative joint condition, but the effects of effusion on knee joint proprioception have not been investigated in detail..

Jan MH, Tang PF, Lin JJ, Tseng SC, Lin YF, Lin DH. The objective of this study was to investigate the efficacy of high, repetitive, target-matching foot-stepping exercise (TMFSE) performed in a sitting position on proprioception, functional score, and walking velocity for patients with knee osteoarthritis (OA). Forty-nine subjects with knee OA were randomly assigned to the exercise or no intervention groups. The exercise group practiced TMFSE in sitting, 3 sessions weekly for 6 weeks. All subjects underwent assessments of knee reposition error, functional incapacity score, and walking velocity prior to and after intervention. The TMFSE significantly improved reposition error, walking velocity on ground level, time to complete a stairs task, time to complete a figure-of-eight, and score on a functional incapacity scale, in subjects with knee OA after 6-week intervention. In contrast, the control group showed no change in any of the measured tests. Target-matching foot-stepping exercise in ...

*  Fitness Advice
Stretching is an integral part of any workout - lengthening the core muscle groups in preparation for the work ahead. There are 3 core types of stretching to be aware of:. Static stretching - involves the gradual lengthening of a muscle to a stretched position where it is held. PNF stretching (proprioceptive neuromuscular facilitation) - a form of static stretching incorporating isometric contraction of a stretched muscle. In everyday English this means applying an immovable force to a stretched muscle which in turn helps to lengthen the muscle. Ballistic stretching often referred to as dynamic stretching - involves bouncing or movement at the point of maximum stretch. We don't recommend doing this as it can result in injury due to the stretch reflex. If over-stretching through bouncing occurs the result may be a tightening of the muscle rather than the desired loosening. Flexibility is highly joint specific meaning that a high degree of flexibility in one joint doesn't necessarily mean that the ...

*  Exercise interventions for shoulder dysfunction in patients treated for head and neck cancer | Cochrane
Both neck dissection and radiotherapy can cause morbidity to the shoulder joint. 'Neck dissection' is often used to prevent the spread of cancer to the lymph nodes of the neck, however this surgery can cause 'shoulder syndrome'. This is defined as shoulder droop, 'winged scapula' (abnormal protruding of the shoulder blades), an inability to shrug and a dull, non-localized pain that is made worse by movement. Shoulder problems can be present in as many as 50% to 100% of patients who have had a radical neck dissection.. Physiotherapy interventions are used to reduce the impact of surgery on the shoulder and include a wide range of rehabilitative techniques. These include passive, active or active-assisted range of motion exercises (the patient's joint is moved either by an external force (e.g. device or person) or active muscle contraction or a combination); progressive resistance training (the patient exercises the muscle against an external force); and proprioceptive neuromuscular facilitation ...

*  Proprioception can contribute to the localization of visual targets for goal-directed movements » Brill Online
When we want to make accurate hand movements to for instance a visual target, it is assumed that we combine visual and proprioceptive information to localize our hand precisely. It has been suggested that you do the same for visual targets. In this case, visual localization is based on the target's position relative to your fovea, and proprioceptive localization is relative to your hand. If you cannot see your hand, this proprioceptive target information will degrade, as updating the location of the target relative to your moving hand adds noise. If this proprioceptive estimate of the target is relevant, movements will become more precise and accurate if we are able to keep a proprioceptive estimate, for instance by placing the other (invisible) hand near the target. This unseen hand does not add new information; it only copies the visual information to proprioception. We tested this prediction by asking subjects to repeatedly move their right index finger between several ...

*  Analysis of a Tele-Operated MRI-Compatible Vane Actuator for Neuromuscular Facilitation in Hemiparetic Limbs | Volume 2:...
This paper analyzes the suitability of pneumatically driven, MRI-compatible vane actuators for stroke rehabilitation, particularly functional recovery of hemiparetic limbs. Hemiparesis patients suffer a sudden loss of motor skills in the upper-limb due to brain injury, such as stroke. As an emerging physio-therapy technique for hemiparesis, named repetitive facilitation exercise, or RFE, a therapist manually applies brief mechanical stimuli to the peripheral target muscles (e.g., tapping, stretching of tendon/muscle) followed by wrist pronation/supination immediately before a patient intends to produce a movement with the muscle. In an earlier study, a robotic system that replicates the mechanical tendon stimulation part of RFE procedure in MRI with the required timing precision has been developed and tested by the authors to investigate the underlying principles of functional recovery via RFE. This work presents the design of a vane actuator that fits into the tight space in MR-scanners, and ...

*  "Central Suppression of Regenerated Proprioceptive Afferents" by Valerie K. Haftel, Edyta K. Bichler et al.
Long after a cut peripheral nerve reinnervates muscle and restores force production in adult cats, the muscle does not respond reflexively to stretch. Motivated by the likelihood that stretch areflexia is related to problems with sensing and controlling limb position after peripheral neuropathies, we sought to determine the underlying mechanism. Electrophysiological and morphological measurements were made in anesthetized rats having one of the nerves to the triceps surae muscles either untreated or cut and immediately rejoined surgically many months earlier. First, it was established that reinnervated muscles failed to generate stretch reflexes, extending observations of areflexia to a second species. Next, multiple elements in the sensorimotor circuit of the stretch reflex were examined in both the PNS and CNS. Encoding of muscle stretch by regenerated proprioceptive afferents was remarkably similar to normal, although we observed some expected abnormalities, e.g., increased length threshold. However,

The health of primary sensory afferents supplying muscle has to be a first consideration in assessing deficits in proprioception and related motor functions. Here we discuss the role of a particular proprioceptor, the IA muscle spindle proprioceptor in causing movement disorders in response to either regeneration of a sectioned peripheral nerve or damage from neurotoxic chemotherapy. For each condition, there is a single preferred and widely repeated explanation for disability of movements associated with proprioceptive function. We present a mix of published and preliminary findings from our laboratory, largely from in vivo electrophysiological study of treated rats to demonstrate newly discovered IA afferent defects that seem likely to make important contributions to movement disorders. First, we argue that reconnection of regenerated IA afferents with inappropriate targets, although often repeated as the reason for lost stretch-reflex contraction, is not a complete explanation. We present ...

*  control-oriented interoceptive inference | Philosophical Transactions of the Royal Society B: Biological Sciences
Key challenges for formal accounts of brain function are emotion, self-awareness and their disorders. Recently, people have started to cast emotional processing in terms of predictive coding or inference about interoceptive or bodily states [9,10,53,54]. The basic argument follows the explanation for action above, namely, motor reflexes are driven by proprioceptive prediction errors. Proprioceptive prediction errors compare primary afferents from stretch receptors with proprioceptive predictions that descend to alpha motor neurons in the spinal cord and cranial nerve nuclei. This effectively replaces descending motor commands with proprioceptive predictions, which are fulfilled by peripheral reflexes [24]. These predictions rest on deep hierarchical inference about states of the world, including our own body. Replacing proprioceptive signals with interoceptive signals, one can see how autonomic reflexes can transcribe descending interoceptive predictions into physiological homoeostasis (e.g. ...

I appreciate your feedback on this, and I think your consideration of yi in light of proprioception is helpful. As I think you are suggesting, to think of yi as "mind," independent of the intended somatic action would miss the point. I've come to understand yi as more than what may be implied by "mind intent." Yi implies a unity of intention and action. According to A.C. Graham, yi "includes both the image or idea of a thing and the intention to act which is inseparable from it. . . ." (Disputers of the Tao, p. 133) Elsewhere, Graham quotes the Song thinker Chao Yuezhi's use of a fine metaphor: ". . . 'intention' [yi] is a combination of 'mind' [xin] and 'sound' [yin]. It is like striking a drum. The sound is not separate from the drum; it comes out from the drum. Intention is not separate from the mind; it is an emission of the mind." (Graham, Two Chinese Philosphers, p. 63) As such, yi does not stop with an initial idea, image, or mental impulse. It includes the feedback experience of the ...

It is quite possible to maintain that consciousness is a biological property of the brain (in humans and certain other animals) without believing it has to be naturalized, forced into categories we would use strictly for the natural world (physical, spatio-temporal, causally closed). Precisely, there is no need to naturalize it, Searle would say: it already is natural. This would be like "seeking to electrify electricity." But notice the problem: if consciousness is indeed such a natural entity, then it can be studied like any other biological process.

Researchers from the Kennedy Krieger Institute and Johns Hopkins University School of Medicine have collaborated to uncover important new insights into the neurological basis of autism. Their new study, published in the journal Nature Neuroscience, examined patterns of movement as children with autism and typically developing children learned to control a novel tool. The findings suggest that children with autism appear to learn new actions differently than do typically developing children. As compared to their typically developing peers, children with autism relied much more on their own internal sense of body position (proprioception), rather than visual information coming from the external world to learn new patterns of movement. Furthermore, researchers found that the greater the reliance on proprioception, the greater the child's impairment in social skills, motor skills and imitation ...

INTRODUCTION: It has been reported that AIS rely much more on ankle proprioception to control the amplitude of the balance control commands as compared to age-matched healthy adolescents. Our hypothesis was that AIS do not neglect proprioceptive information to control posture probably because of their vestibular deficits. We investigated the proprioceptive contribution to postural control in AIS which expresses spinal deformity during a crucial transitional period of ontogenesis. METHODS: 10 adolescents with idiopathic scoliosis (AIS) with moderate spinal deformity (10° , Cobb Angle ,35°) and 10 control adolescents (CA) had to maintain vertical stance while very slow oscillations in the frontal plane (below the detection threshold of the semicircular canal system) were applied to the support with the eyes open and closed ...

Background Visual adaptation to laterally displacing prisms has long been used to induce sensorimotor conflict in order to investigate multisensory integration.1 When pointing toward a target viewed through lateral displacing prisms, there is an initial error in pointing, and misalignment between visual and propriceptive reference frames; but repeated trials result in adaptation, with re-alignement of vision and proprioception and accurate pointing. After removing the prisms, prism adaptation (PA) can be observed as a pointing error in the opposite direction of the prismatic shift-the adaptation after-effect. Previous work has suggested that patients optic ataxia due to lesions to the IPS utilise visual and proprioceptive information differently to healthy participants when carrying out visuo-motor calculations that allow them to reach for visual targets.2 ...
