Motor and Sensory Areas of the Cortex01:14

Motor and Sensory Areas of the Cortex

7.5K
The cerebral cortex, the brain's outermost layer, is pivotal in processing complex cognitive tasks, emotions, and various sensory inputs and executing voluntary motor activities. This intricate structure is divided into three primary functional areas: the motor areas, sensory areas, and association areas.
Motor Areas
The motor areas located in the frontal lobe are central to controlling voluntary movements. This region is further subdivided into the primary motor cortex and the premotor cortex....

What is a Sensory System?01:31

What is a Sensory System?

101.1K
Sensory systems detect stimuli—such as light and sound waves—and transduce them into neural signals that can be interpreted by the nervous system. In addition to external stimuli detected by the senses, some sensory systems detect internal stimuli—such as the proprioceptors in muscles and tendons that send feedback about limb position.

Pain01:20

Pain

1.4K
Pain serves as a critical warning signal that alerts the body to potential or actual harm. When mechanical pressure on the skin is intense, such as from a sharp pinch, the sensation transitions from touch to pain. Similarly, extreme temperatures, like a hot pot handle, convert the sensation of heat into pain. Pain can also result from overstimulation of other senses, such as blinding light, loud noise, or the intense heat from habañero peppers. This ability to sense pain is essential for...

Arteries of Lower Limbs01:20

Arteries of Lower Limbs

4.7K
The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular...

Veins of Lower Limbs01:15

Veins of Lower Limbs

2.5K
The human body consists of an intricate network of veins responsible for the crucial task of blood drainage from the lower limbs. These veins can be categorized into two main types: deep veins and superficial veins.
Formed by the union of the medial and lateral plantar veins, the posterior tibial vein, rising through the calf muscle, assimilates the fibular vein. The anterior tibial vein, a superior extension of the foot's dorsalis pedis vein, merges with the posterior tibial vein at the...

Sensory Modalities01:15

Sensory Modalities

3.9K
Sensation typically is the process by which the sensory receptors and sense organs detect stimuli from the internal and external environment and transmit this information to the central nervous system for processing.
General senses refer to the broad category of sensory information detected by receptors in the body and can be further grouped into somatic and visceral senses. Somatic sensations include touch, pressure, temperature, and pain and are essential for navigating our environment and...

Summary

Phantom limb pain (PLP) in amputees was significantly reduced using a novel sensory-motor training program. This approach normalizes phantom limb control by integrating visual and tactile feedback, offering a new treatment avenue.

Area of Science:

  • Neuroscience
  • Rehabilitation Medicine
  • Pain Management

Background:

  • Phantom limb pain (PLP) affects 85% of amputees, with unknown causes and limited effective treatments.
  • A potential mechanism for PLP involves the correlation between phantom limb motor control and sensory feedback from motor intention.

Purpose of the Study:

  • To investigate the efficacy of a novel sensory-motor training strategy for reducing phantom limb pain intensity.
  • To explore the use of visual and tactile feedback to normalize motor commands for phantom limb control.

Main Methods:

  • Ten upper-limb amputees with chronic PLP participated in 16 days of intensive phantom-limb movement control training.
  • The training incorporated visual and tactile feedback driven by stump muscular activity to guide phantom limb movements.

Main Results:

  • A 21.6% reduction in PLP intensity was observed immediately post-training, increasing to 32.1% at 6-week follow-up.
  • The results indicate clinical effectiveness for chronic pain reduction.

Conclusions:

  • Multimodal sensory-motor training with visual and tactile feedback is a promising new method for reducing phantom limb pain.
  • This training protocol effectively reduces PLP by improving phantom limb motor output via stump muscle activity feedback.
