- No Dictionary Found. This is a general term which may be applied to materials or structures. When a force is applied to a structure, there is a displacement in the direction of the force; stiffness is the ratio of the force divided by the displacement.

What Causes Muscle Stiffness? Muscle stiffness is caused when the muscles in a certain area of the body contract and become tense. Stiff muscles can happen from a variety of situations. These situations can range from having periods of inactivity to exercising, physical labor or playing sports.xperiencing stiffness in the hip area is usually a result of arthritis or a more serious medical condition like Antley-Bixler syndrome or hypophosphatemic rickets. Antley-Bixler Syndrome and arthritis cause stiffness in the knees.

Stiffness Elastic modulus is a property of the constituent material; stiffness is a property of a structure. That is, the modulus is an intensive property of the material; stiffness, on the other hand, is an extensive property of the solid body dependent on the material and the shape and boundary conditions. is the force applied on the body. δ is the displacement produced by the force along the same degree of freedom (for instance, the change in length of a stretched spring). In the International System of Units, stiffness is typically measured in newtons per meter.

Loudness For the Japanese band, see Loudness (band). Loudness is the characteristic of a sound that is primarily a psycho-physiological correlate of physical strength (amplitude). More formally, it is defined as that attribute of auditory sensation in terms of which sounds can be ordered on a scale extending from quiet to loud.

String Stiffness â The Alpha and Omega of String PerformanceCrawford Lindsey, Tennis Warehouse, San Luis Obispo, CA, 93401 String stiffness is measured at a particular tension to show how one string compares to another under the same circumstances. In our tests, string stiffness is the measured value obtained by impacting one piece of string at a tension of 62 lbs.

Hypertonia Rigidity is a severe state of hypertonia where muscle resistance occurs throughout the entire range of motion of the affected joint independent of velocity. It is frequently associated with lesions of the basal ganglia.

Definitions &Translations Freebase(0.00 / 0 votes)Rate this definition: Viscosity. The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress. For liquids, it corresponds to the informal notion of thickness. For example, honey has a higher viscosity than water.

- Only you can say that you’re stiff. Stiffness and tightness are imprecise symptoms and sensations — they are completely subjective, and only loosely related to anything that can be objectively measured, like ROM. No instrument can confirm it. Most people think of stiffness as a bad thing.

Spasticity What is spasticity? Spasticity is a side effect of paralysis that varies from mild muscle stiffness to severe, uncontrollable leg movements. Generally, doctors now call conditions of extreme muscle tension spastic hypertonia (SH). It may occur in association with spinal cord injury, multiple sclerosis, cerebral palsy, or brain trauma.

- Stiff Person Syndrome (SPS) is a rare disease of the nervous system. Progressively severe muscle stiffness typically develops in the spine and lower extremities; often beginning very subtly during a period of emotional stress. Most patients experience painful episodic muscle spasms that are triggered by sudden stimuli.
