Summary
The Lower Extremity Position Test (LEPT) is a reliable tool for assessing lower limb proprioception in stroke survivors, showing significant differences between affected and unaffected limbs. This inexpensive test aids in evaluating post-stroke motor function.
Area of Science:
- Neurorehabilitation
- Biomechanics
- Clinical Assessment
Background:
- Proprioception deficits are common after stroke, impacting motor control and functional recovery.
- Accurate assessment of lower extremity proprioception is crucial for targeted rehabilitation strategies.
- Existing assessment tools may be costly, complex, or lack reliability.
Purpose of the Study:
- To develop a quantitative, inexpensive, and user-friendly tool for assessing lower extremity proprioception in post-stroke individuals.
- To evaluate the test-retest reliability of this new tool.
- To examine its known-groups validity by comparing involved and uninvolved lower extremities.
Main Methods:
- Development of the Lower Extremity Position Test (LEPT) involving reproduction of specific distances (12cm, 22cm) by seated subjects.
- Measurement of deviation as a mismatch score.
- Test-retest reliability and known-groups validity assessed in 51 post-stroke individuals over one week using t-tests, ICC, and Bland-Altman analysis.
Main Results:
- The involved lower extremity demonstrated significantly higher mismatch scores compared to the uninvolved limb (p < 0.0001).
- The LEPT exhibited good test-retest reliability for both distances on the involved leg (ICC = 0.79 for 12cm, 0.85 for 22cm).
- Repeatability ranges were found to be leg-dependent.
Conclusions:
- The Lower Extremity Position Test (LEPT) is a novel assessment tool with good clinical utility for the post-stroke population.
- The LEPT is reliable and demonstrates known-groups validity, distinguishing between involved and uninvolved lower extremities.
- This tool offers a practical and effective method for evaluating lower limb proprioception deficits post-stroke.

01:29Angina III: Clinical Manifestations and Assessment
208
Angina manifests as chest pain, tightness, or squeezing discomfort typically located behind the breastbone. It can radiate to the neck, jaw, shoulders, and inner aspects of the upper arms, most commonly the left arm. Patients may experience shortness of breath, fatigue, profuse sweating, dizziness, indigestion, heartburn, palpitations, anxiety, and vomiting as accompanying symptoms. This pain often lasts a few minutes and is triggered by physical exertion, emotional stress, heavy meals, or cold...

01:22Absolute and Local Extreme Values
56
The highest and lowest values of a function, relative to a reference axis, are known as extreme values. These include absolute maximum and absolute minimum values, which represent the highest and lowest points the function reaches across its entire domain. Within a restricted portion of the function, the highest and lowest values are referred to as local maximum and local minimum values, respectively.Periodic functions, such as sine and cosine, show extreme values at infinitely many points due...

In 1928, a German botanist Emil Heitz observed the moss nuclei with a DNA binding dye. He observed that while some chromatin regions decondense and spread out in the interphase nucleus, others do not. He termed them euchromatin and heterochromatin, respectively. He proposed that the heterochromatin regions reflect a functionally inactive state of the genome. It was later confirmed that heterochromatin is transcriptionally repressed, and euchromatin is transcriptionally active chromatin.

01:31Position and Displacement
24.9K
The position of an object defines its location relative to a convenient frame of reference at any particular time. A frame of reference is an arbitrary set of axes from which the position and motion of an object are described. Earth is often used as a frame of reference, and we often describe the position of an object as it relates to stationary objects on Earth. For example, a rocket launch could be described in terms of the position of the rocket with respect to Earth as a whole. On the other...

01:03Serial Position Effect
531
The serial position effect is a cognitive phenomenon where individuals are more likely to recall the first and last items in a list compared to those in the middle. This effect is divided into the primacy effect and the recency effect. The primacy effect is observed when the initial items in a list are remembered better. This occurs because these items are rehearsed more frequently or receive more elaborative processing, allowing them to be encoded into long-term memory more effectively. For...

01:11Anatomical Positions
19.5K
In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...
