PEMF — pulsed electromagnetic field therapy — applies low-frequency electromagnetic pulses to tissue to reduce pain and support recovery. At Fit Body Therapy in Los Altos it is used inside orthopedic sessions, typically for chronic pain, joint stiffness, and soft tissue recovery that has plateaued. Sessions are one-on-one with Angelo dela Cruz, practicing since 1996.
What PEMF Is
PEMF devices generate pulsed electromagnetic fields at low frequencies and deliver them into tissue. Unlike heat, light, or pressure, the field passes through clothing and skin without needing direct contact and without generating meaningful heat.
The therapy is not new or fringe. Electromagnetic bone growth stimulators have been FDA-cleared for decades for treating nonunion fractures, and PEMF appears in orthopedic practice, veterinary medicine, and sports recovery worldwide. That is a useful anchor: this is an established clinical technology, whatever the wellness industry has since layered on top of it.
An Honest Read on the Evidence
PEMF attracts some of the most extravagant marketing in the recovery space — cellular recharging, mitochondrial optimization, detoxification. Separating what holds up:
Well established: bone healing in nonunion fractures, where the clearance and the clinical record are both solid.
Reasonable support: reduced pain in osteoarthritis and chronic musculoskeletal conditions, reduced local inflammation, improved local circulation.
Plausible but thinner: accelerated soft tissue recovery and reduced post-exercise soreness. Real mechanism, variable study quality.
Not supported: that it detoxifies you, recharges your cells, or clears energetic blockages. Those claims are marketing, not physiology, and they undermine a modality that has a legitimate case to make.
The practical framing here: PEMF is a supporting tool that helps a stalled recovery move again. It is not the reason your pain will resolve — the mechanics we correct with hands-on work are.
When It Gets Used
- Chronic pain that has not responded well to manual therapy alone
- Joint stiffness and arthritic discomfort, particularly knees and hips
- Tendon and ligament recovery where healing has plateaued
- Post-surgical recovery, once cleared by your surgeon
- Areas too painful for hands-on work — PEMF requires no direct pressure
What a PEMF Session Feels Like
Painless and non-invasive. You lie comfortably while the device delivers rhythmic pulses to the target area. Most people report a gentle tapping or pulsing sensation, sometimes mild warmth or tingling; many find it meditative and a fair number fall asleep.
PEMF runs 10 to 30 minutes inside your session, usually alongside manual therapy on other regions so no time is wasted. There is no recovery period and nothing to manage afterward.

Frequently Asked Questions
Is PEMF safe?
For most people, yes — it is non-invasive and generates no meaningful heat. It is not used with implanted electronic devices such as pacemakers or defibrillators, during pregnancy, or over active bleeding, and these are screened for beforehand.
Does it actually work, or is it hype?
Both, depending on the claim. Bone healing and pain reduction in chronic musculoskeletal conditions have real support. Cellular recharging and detoxification do not. It is a useful supporting tool with a genuine evidence base and a great deal of marketing noise around it.
How many sessions will I need?
PEMF is not prescribed as a standalone course here. It is used within your treatment plan for as long as it is contributing, and dropped when it is not.
Can I feel anything during treatment?
Most people feel a light pulsing or tapping and sometimes mild warmth. Some feel very little. Sensation intensity is not a measure of effect.
Book a session in Los Altos. If your recovery has stalled, PEMF may be one of the things that gets it moving again.
