Parkinsonian Rigidity Depends on the Velocity of Passive Joint Movement

This video is a part of a larger group of videos that were created during the symposium. When ever there is resistance to movement, think of the two most common issues: spasticity and rigidity. Both spasticity and rigidity represent hypertonic states, however both have different causes and characteristics that are important to be aware of.

Can you differentiate between spasticity versus rigidity? This is our first video release from our Stanford 25 Skills Symposium. In this short excerpt, Dr. Steve McGee talks about the approach to differentiating spasticity versus rigidity at the bedside. We teach bedside medicine. We emphasize the importance of the physical exam and how it can help care for your patient and also create an environment where the person you are caring for develops trust.

We have taught this now for over 6 years when the Stanford Medicine 25 was first created. A 78 year old man with no significant past medical history presents to his primary care physician with 4 days of right shoulder pain.

The pain is located over the acromioclavicular joint. The pain is worse at night with lying down and associated with shortness of breath. He states that the pain is better during the day. He is an avid ping pong player and does not have pain or shortness of breath with playing ping pong The 25 The 25 Visit the Abraham Verghese Interviews Dr. Jerome Kassirer on New Book Signs of Scleroderma can-improv-help-doctors conversation-about-bedside-medicine-gains-momentum.

Spasticity

The pendulum test is a sensitive clinical assessment of spasticity where the lower leg is dropped from the horizontal position and features of limb motion are recorded. Three key kinematic features are associated with the degree of severity of spasticity in children with cerebral palsy: decreased initial limb excursion, reduced number of limb oscillations, and a non-vertical resting limb angle. While spasticity is attributed to increased velocity-dependent resistance to motion, prior models simulating increased sensorimotor feedback of muscle velocity fail to explain the key pendulum test kinematic outcomes in spastic individuals. Here we hypothesized that increased muscle tone, causing a transient increase in muscle force, i. We further hypothesized that hyperreflexia modeled based on muscle fiber force, and not velocity, feedback would be necessary to reduce the number of oscillations because of its interaction with transiently increased muscle force due to short-range stiffness.

Already a member? Sign in. Muscle tightness , muscle weakness , muscle rigidity , nursing , qualitative research. Purpose: This study examined the nature of muscle tightness from nurses' perspectives and explored how the symptoms of muscle tightness are communicated, managed, and differentiated from other conditions, such as muscle rigidity and muscle weakness. Design : An exploratory, descriptive qualitative design was used. Methods: Eight rehabilitation nurses described lexicons, care strategies, and communication for muscle tightness, weakness, and rigidity. Findings: Nurses used conflicting terms to describe muscle tightness, weakness, and rigidity.

Spasticity versus Rigidity (Stanford 25 Skills Symposium, 2015)

Spasticity is a form of muscle overactivity that significantly impedes physical movements or motor functioning.

It has been long believed that Parkinsonian rigidity is not velocity-dependent based on the neurological examination. However, this has not been verified scientifically. The elastic coefficient was not velocity-dependent, but the difference in bias increased in a velocity-dependent manner.

Spasticity is a condition where a number of muscles suffer continuous contraction, stiffness, and tightness. It is caused by lesions in the pyramidal tract i. Spasticity is characterized by spasm, especially the tonic spasm. This kind of stiffness or spasm interferes with the speech, normal movement and gait. Spasticity is uni-directional, i.
