muscle stiffness caused by an increase in contractions of the muscle fibers

increased muscle tone. It may be worsened by the wrong posture, squeezing a soft ball both of which should be avoided.

A state of increased tone of a muscle (and an increase in the deep tendon reflexes). For example, with spasticity of the legs (spastic paraplegia) there is an increase in tone of the leg muscles so they feel tight and rigid and the knee jerk reflex is exaggerated.

increased tone as a result of an upper motor neuron lesion

Increased tone or contractions of muscles causing stiff and awkward movements; the result of upper motor neuron lesion.

hypertonia, characterized by increased muscle tone, increased tendon reflexes, and pathological reflexes (Babinski sign)

a velocity-dependent increase in muscle resistance to passive movement accompanied by increase stretch reflexes and clonus (intermittent muscular contractions). Spasticity is due to uninhibited activity in spinal circuits and is not the same thing as hypertonicity (excessive tone in muscular structure).

State of continuous muscle contraction that the person cannot control.

Having sudden, involuntary muscle spasms or tense, contracted muscles.  Muscles are spastic, people are not.

increased muscle tone - when you try to bend the arm or leg there is an increased resistance to movement which eventually 'gives'

Stiffness or position that is difficult to release.

Abnormal tightness or stiffness in a muscle.

the quality of moving or acting in spasms

A state of hypertonicity or increase over the normal tone of a muscle, with heightened deep tendon reflexes.

Abnormal elevation in baseline muscle tension and resistance to movement.

Continuous contraction of certain muscles.

Increased muscle tone - tightness or stiff muscles, usually around a joint. - Increased resistance to movement. It refers to the stiffness that can occur in a limb, usually in the leg. Spasticity often accompanies weakness, but it is possible to have spasticity without weakness and to have weakness without spasticity.

Abnormal increase in muscle tone, manifested as a spring like resistance to moving or being moved.

A motor disorder characterized by tight or stiff muscles that may interfere with voluntary muscle movements and is a problem for many patients with multiple sclerosis (MS), spinal cord injury (SCI), cerebral palsy (CP), and acquired brain injury (ABI).

A condition characterized by rigid or stiff muscles and extreme deep tendon reflexes that interfere with muscular activity, gait, speech or movement.

Muscle spasms causing stiff and awkward movements

Sudden and violent involuntary muscle contractions

Abnormally increased tone in a muscle.

Muscle tone marked by very high tension. Interferes with voluntary movement and can lead to stiffening of muscles around a joint.

Increased tightness or tone in the arms and/or legs, making the patient less flexible; the arms and/or legs seem stiff.

An involuntary increase in muscle tone (tension) that occurs following injury to the brain or spinal cord, causing the muscles to resist being moved. Characteristics may include increase in deep tendon reflexes, resistance to passive stretch, clasp knife phenomenon, and clonus.

Terminology used to describe stiff, tight, or rigid muscle tone.

A state of increase over the normal tension of a muscle resulting in continuous increase of resistance of stretching.

increased muscle tone that results in a tightening and shortening of a muscle.

An increase in muscle tone with exaggerated tendon reflexes.

involuntary muscle contractions leading to spasms and stiffness or rigidity. In MS, this condition primarily affects the lower limbs.

stiffness of the body involving the limbs that results from dysfunction of the corticospinal tracts.

a condition characterized by increased muscle tone, exaggerated reflexes and increased resistance to passive movement.

Uncontrollable muscle contraction.

Hyperactive muscles that move or jerk involuntarily. There are some benefits to spasticity: Warning mechanism to identify pain or problems in areas of no sensation. Helps in spotting an oncoming urinary tract infection. Helps to maintain muscle size and bone strength. Helps to maintain circulation. Helps to prevent osteoporosis.

The increased stiffness or 'muscle tone' experience by children with cerebral palsy. Muscle spasm can often be felt when such a child's limbs are moved. The limbs are hard to bend or straighten because of the spasticity of the muscles. The doctor usually finds increased tendon jerks in a child with spasticity.

an abnormal increase in muscle tone that may be caused by certain types of damage to the nerve pathways regulating muscles. Spasticity can lead to incoordination, loss of function, pain and permanent muscle shortening, or contracture.

An increase in muscle tone often caused by damage to central motor pathways that control voluntary movements.

uncontrolled contractions of muscles

increased tone in muscles of the arms and legs (due to lesions of the upper motor neurons).

An abnormal increase in muscle tone leading to muscle stiffness and rigidity.

permanently increased muscle tone

A movement disorder characterized by abnormally high muscle tone, causing stiffness or tightness of the muscles that may interfere with gait, movement and speech.

Increased involuntary muscle contraction (the opposite of hypotonicity).

Hypertonicity of a muscle, characterized by hyperactivity of the stretch reflex.

Increased resistance to muscle stretching and loss of normal elasticity of leg and/or arm muscles resulting from CNS disease process. Often manifested by muscle stiffness, which can result in difficulty with movements of the extremities. Steroids (See Cortisone).

Spasticity means an increase over the normal tone of a muscle, with heightened deep tendon reflexes.

Resistance to the passive movement of a limb that is maximal at the beginning of the movement and gives way as more pressure is applied. Spasticity is usually accompanied by weakness in the affected limb.

A state of increased muscle tone with exaggerated tendon reflexes that move or jerk involuntarily. Such uncontrolled muscle activity is caused by excessive reflex activity below the level of lesion.

Increased tightness or tone in the arms and/or legs, making one less flexible and possibly causing the arms and/or legs to stiffen.

Increased muscle tone (hypertonic), involuntary resistance of weak muscle caused by passive range of motion followed by sudden relaxation of muscle, associated with exaggeration of reflexes. Causes stiffness, awkward movements, and loss of voluntary muscle control.

A condition characterized by increase muscle tone due to damage in the upper motor neuron.

Spasticity is a disorder of the body's motor system in which certain muscles are continuously contracted. This contraction causes stiffness or tightness of the muscles and may interfere with gait, movement, and speech. The person with the spastic muscles may or may not feel it, know about it or want to do something about it.
