Updated: Feb 04, Physical and Occupational Therapy. Spasticity is increased, involuntary, velocity-dependent muscle tone that causes resistance to movement. The condition may occur secondary to a disorder or trauma, such as a tumor, a stroke, multiple sclerosis MScerebral palsyor a jacjson cordbrainor peripheral nerve injury. Equinovarus positioning of the foot is a common posture in the lower extremity, and it can be a major limitation to functional transfers or gait as a weiyht grows older.
The following patterns often are seen in patients with cerebral palsy, stroke, baptist weight loss jackson ms traumatic brain injury TBI baptist weight loss jackson ms The following flexor patterns often are seen in patients with cerebral palsy, MS, or TBI or who have suffered a stroke: See Clinical Presentation for more detail. In patients with new-onset spasticity, a thorough history and physical examination, as well as examination using electromyography, a determination of nerve conduction velocities, or imaging studies of the head, neck, and spine may be useful in eliminating treatable causes of increased tone.
Laboratory studies eg, complete blood count [CBC] and culturing of jacksson, blood, cerebrospinal fluid may help to rule out infection. Spasticity is difficult to quantify. Treatment weight loss supplements safe while breastfeeding do not need baptist weight loss jackson ms be used in a stepladder approach and indeed should not be.
Current spasticity management options include the following: See Treatment and Medication for more detail. See Pathophysiology and Etiology. Spasticity usually is accompanied by paresis and other signs, such as increased stretch reflexes, which collectively are called upper motor neuron syndrome. Paresis particularly affects distal muscles, with loss of the ability to perform fractionated movements of the digits.
Upper motor neuron syndrome results from damage to descending motor pathways at the cortical, brainstem, or spinal cord levels. When the injury that leads to spasticity is acute, muscle tone is flaccid with hyporeflexia before the appearance of spasticity. The interval between injury and the appearance of spasticity varies from days to months bapttist to the level of the lesion. In addition to deight and increased muscle tone, the signs in spasticity include the following see Clinical Presentation : Spasticity can be severely debilitating, but with appropriate neurologic, surgical, rehabilitative, and psychosocial interventions, its manifestations can be treated, thus greatly improving the quality of life of affected individuals.
See Prognosis, Treatment, and Medication. While the incidence of spasticity is not known with certainty, the condition likely affects baptkst half a million people in the United States and over 12 million people worldwide. The pathophysiologic basis of spasticity is incompletely understood. Polysynaptic responses may be involved in spinal cord—mediated spasticity, while enhanced excitability of monosynaptic pathways is involved in cortically mediated spasticity.
Spasticity-related changes in muscle tone probably result from alterations in the balance of inputs from reticulospinal and other descending pathways to the motor and interneuronal circuits of the spinal cord, along with the absence of an intact corticospinal system. Loss of descending tonic or phasic excitatory and inhibitory inputs to the spinal motor apparatus, alterations in the segmental balance of excitatory and inhibitory control, denervation supersensitivity, and neuronal sprouting may be observed.
Once spasticity is established, the chronically shortened muscle may develop physical changes, such as shortening and contracture, that further contribute to muscle stiffness. Lesions involving area 6 cause impairment of postural control in the contralateral limbs. Combined lesions of areas 4 and 6 cause both paresis and spasticity to develop.
