🖐️ SMALL MUSCLES—BIG JOBS: THE LUMBRICALS
Deep within the palm are four slender muscles called the lumbricals. Unlike most muscles, they begin on tendons and attach to the finger extensor mechanism. They help bend the large knuckles while simultaneously straightening the middle and end joints of the fingers—a coordinated movement needed for writing, typing, gripping and other precise hand activities.
When the lumbricals and surrounding tissues become tight or out of balance, you may experience:
• Aching or cramping in the palm
• Finger stiffness or fatigue
• Reduced coordination during fine movements
• Difficulty comfortably opening or closing the hand
• Uneven tension between the finger flexors and extensors
• Discomfort when gripping tools, writing or typing
These symptoms may develop from repetitive gripping, prolonged computer work, hand-intensive occupations, injury, immobilization or compensation for problems elsewhere in the hand, wrist or forearm.
Myofascial release uses gentle, sustained pressure to address restrictions within the palm, fingers, wrist and forearm. Treatment may help reduce excessive tissue tension, improve movement between muscles and tendons, and restore better balance between the structures that bend and straighten the fingers.
The lumbricals may be small, but when they are not working comfortably, your entire hand can feel the difference!
Persistent numbness, marked weakness, swelling or finger locking should also be evaluated by an appropriate medical professional to rule out nerve, tendon or joint conditions.
