Rhythmic upper limb exercise excites lower limb muscles during walking-like tasks. Incorporating simultaneous upper and lower limb rhythmic exercise may improve gait rehabilitation after neurological injury.
Area of Science:
- Neuroscience
- Rehabilitation Medicine
- Motor Control
Background:
- Rhythmic upper limb muscle activation influences lower limb muscle activity.
- Neural coupling between upper and lower limbs is observed during locomotion.
Purpose of the Study:
- To investigate the excitatory effect of rhythmic upper limb activation on lower limb muscles.
- To explore the implications for gait rehabilitation strategies.
Main Methods:
- Studies involved neurologically intact individuals and those with spinal cord injury.
- Locomotor-like tasks were used to assess muscle activation patterns.
Main Results:
- Rhythmic upper limb activation demonstrated an excitatory effect on lower limb muscle activation.
- This effect was observed during simulated walking tasks.
Conclusions:
- Simultaneous rhythmic upper and lower limb exercise is a promising approach for gait rehabilitation.
- Leveraging neural coupling can enhance recovery of motor function after neurological injury.

Muscles that Move the Leg
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed to...
Muscles that Move the Arm
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...
Muscles of the Leg that Move the Foot and Toes
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles.
Muscles that Move the Thigh
Three other significant muscles are the gluteus maximus, gluteus medius, and gluteus minimus. The gluteus maximus originates from the posterior surface of the ilium, sacrum, and coccyx, and the thoracolumbar fascia...
Anatomical Movements
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist, metacarpophalangeal,...
Muscle Coordination and Action
Agonists
Agonist muscles, often called prime movers, are the primary muscles responsible for producing a specific movement.
