What Is Lymphedema and How Does It Affect the Body?
TENS Machine for Lymphedema: How It Works for Relief The lymphatic system plays a vital role in maintaining fluid balance and immune health. It consists of a network of vessels, nodes, and organs like the spleen. When this system fails, it can lead to a buildup of protein-rich fluid in tissues, causing a chronic condition known as lymphedema.
The Lymphatic System’s Role in Fluid Balance
The lymphatic network helps remove excess fluid and waste from the body. It also supports the immune system by filtering harmful substances through lymph nodes. When this process is disrupted, swelling occurs, often in the arms or legs. In severe cases, the affected limb can swell to three times its normal size.
Symptoms and Challenges of Lymphedema
Common symptoms include pitting edema, where the skin retains an indentation when pressed, and skin thickening. Over time, reduced mobility and chronic discomfort can develop. Without proper treatment, risks like cellulitis, ulceration, and recurrent infections increase. Poor drainage can also lead to fatigue and a weakened immune response.
- Pitting edema and skin thickening are early signs.
- Severe cases may cause limb swelling and reduced mobility.
- Untreated lymphedema increases the risk of infections and ulcers.
How a TENS Machine for Lymphedema Provides Relief
Electrical stimulation has emerged as a promising solution for managing chronic swelling. By delivering mild electrical currents, this therapy helps stimulate the movement of lymph fluid, reducing buildup in affected areas. A 2023 study showed a 35% reduction in swelling among users compared to just 12% in control groups.
Stimulating Lymphatic Flow with Electrical Impulses
Electrical pulses increase the velocity of lymph movement by 50-70% in treated limbs. Frequencies between 50-100 Hz optimize capillary filtration and lymph propulsion. This process prevents fluid stagnation by gently massaging the walls of blood vessels.
Additionally, the therapy triggers the release of β-endorphins, which have anti-inflammatory effects. This not only reduces swelling but also enhances overall comfort and mobility. TENS Machine for Lymphedema: How It Works for Relief
