TENS machines work by sending electronic stimulating pulses across the surface of the skin and along the nerve strands. The stimulating pulses help prevent pain signals from reaching the brain. TENS devices also help stimulate your body to produce higher levels of its own natural painkillers, called "Endorphins".
Knee Braces are used to support your knee, especially with walking. These can be used to prevent injury, or after an injury has occurred. Knee braces can be very useful to support your knee if you have arthritis or other degenerative diseases of the knee.
A lumbosacral orthosis (LSO) is a device used to support your back. An LSO is used on the lowest part of the spine. This area includes the lumbar and sacral spine. An LSO is made to fit from your lower back to your tailbone. This include support for the front and back of your lower back. This helps support your lower back by acting like extra muscles.
You may need an LSO if you have a degenerative disc disease, osteoporosis, or pain traveling down your leg. An abdominal binder can help support your lower back by putting compression (pressure) on your abdomen. This helps relieve lower back pain. Some abdominal binders can be used by pregnant women to help with lower back pain.
