Nerve Pain Blocking
Pain interruption. Gentle current.
Persistent low-back, neck, knee, or arthritis pain, TENS is used as a non-drug option to take the edge off and keep you moving.
Nerve Pain Blocking is a TENS-style (Transcutaneous Electrical Nerve Stimulation) session in which small adhesive electrodes deliver a gentle, controlled electrical current to the skin near a painful area. At higher frequencies, the current stimulates large-diameter sensory nerve fibers, and per the long-standing gate-control theory of pain, that input "closes the gate" on slower pain signals before they reach the brain. The sensation is a comfortable buzz or tingle, dialed in by the guide to a level you choose.
TENS devices are regulated by the FDA as Class II medical devices that apply a mild electrical current through skin electrodes to treat pain (21 CFR 882.5890), a long-established, non-pharmacologic option. At Recharge, sessions run about 20–30 minutes and pair naturally with other Charge Studio services that work on the muscle and circulatory side of recovery.
Persistent low-back, neck, knee, or arthritis pain, TENS is used as a non-drug option to take the edge off and keep you moving.
Day-after training soreness, a stiff shoulder, a sore calf, a focused session can quiet the local signal so you can stretch and recover.
An adjunct alongside physical therapy and your provider's plan, helpful for managing discomfort during the rehab window.
When pain quiets down, sleep gets easier, members with nagging discomfort often use a session in the evening to settle the body for rest.
- Gate-control theory of pain. First proposed by Melzack & Wall in 1965 and still the dominant model: stimulating large-diameter (Aβ) sensory fibers in the skin can inhibit transmission of slower nociceptive signals at the spinal cord, effectively "closing the gate" on pain.
- High-frequency, conventional TENS. The setting used most often at Recharge: strong but comfortable tingle, ~50–100 Hz, short pulse width. Onset is fast and the effect is local to the area being treated.
- FDA-cleared, drug-free. TENS units are regulated as Class II medical devices in the U.S. and are widely used in pain clinics, physical therapy, and home settings as a non-pharmacologic option for managing pain.
- Stacks well with movement. Because TENS reduces the perceived pain signal during a session, it pairs naturally with the gentle mobility, stretching, and muscle work many members do in the same Charge Studio visit.
For an acute flare or a sore spot, one focused session on the area that's bothering you.
A structured cadence for chronic discomfort, most evidence-based clinical protocols sit in this range.
Run it alongside Micro-Current Therapy or Compex EMS in the same Charge Studio visit for a fuller recovery stack.
Approach with care if you have:
None of these are off-limits, our team will walk you through a personalized routine during your consultation. If anything below sounds like you, mention it on your visit so we can adjust placement, intensity, or whether TENS is the right tool for the day. When in doubt, see your physician first.
- ·A pacemaker, implanted defibrillator, or any other implanted electronic device
- ·Pregnancy (especially over the abdomen or low back), unless cleared by your provider
- ·Broken, irritated, or numb skin where pads would be placed
- ·Epilepsy or certain seizure disorders, particularly with electrode placement on the head, neck, or chest
- ·Undiagnosed pain, see a physician first to rule out a cause that needs direct treatment
- ·Active cancer in the area being treated, unless cleared by your oncology team
