Another complication associated with the loss of pain sensation, proprioception and muscular reflexes that regulate joint movement is Charcot neuroarthropathy (CN) [38].
Included in these tests were activity in the open field, forelimb grip strength, and muscular reflexes.
Additionally, they underwent a systematic medical assessment, which included serum creatine kinase level, electrocardiography (ECG), echocardiography, muscular tension, and muscular reflexes of the proximal and distal muscles of the lower and upper limbs.
The activity of joint receptors, muscle spindles and Golgi tendon organs may be reduced by fatigue, resulting in proprioceptive deficit in muscle receptors and loss of muscular reflexes responsible for dynamic joint stability [ 31].
The activity of joint receptors, muscle spindles and Golgi tendon organs may be reduced by fatigue, resulting in proprioceptive deficiency in muscle receptors and loss of muscular reflexes responsible for joint stability [ 10].
The increase in joint laxity following fatigue has been suggested to be due to reduced muscle tone [ 38], viscoelastic changes in the collagenous tissues of the knee and fatigued muscle stabilizers [ 14], and results in inadequate ligament mechanoreceptor feedback, which is required to elicit the muscular reflexes responsible for joint stability [ 10].
Built up into complex patterns of many coordinated muscular actions, reflexes form the basis of much instinctive behaviour in animals.
Yet, abnormal neuro-mechanical conditions such as hypertonia can encompass alteration of inter-muscular (heteronymous) reflexes [10] or abnormal multi-joint couplings due to increased rigidity [11],[11].
Degree of central nervous system depression was classified as level I (mildly affected, voluntary movement and intact reflexes), level II (no voluntary movement and intact reflexes), level III (unconsciousness, depressed reflexes, muscular relaxation) and level IV (ceased respiration, dilated pupils).
Background: Several recent studies in animal models of spinal pain have shown changes in sensory processing and in reflex muscular responses.
