Medical Benefits

Effective Pain Management

Longest MStim Reha 231 is effective in reducing pain caused by a wide range of conditions including:

  • Periarthritis
  • Arthritis
  • Period pain
  • Sports injuries
  • Multiple sclerosis
  • Fibromyalgia
  • Spinal cord injury
  • Postoperative pain
  • Joint pain
  • Neck and back pain
  • Pelvic pain

Stop Incontinence

The pelvic floor muscles surround the bladder and urethra and control the flow of urine as you pee. Stress urinary incontinence (SUI) is usually caused by the pelvic floor muscles being weak or damaged. Problems with these muscles may be caused by:

  • Pregnancy or obesity – increase pressure on your tummy
  • Vaginal birth – might cause damage to the muscle during childbirth
  • The bladder or nearby area during surgery
  • Neurological conditions that affect the brain and spinal cord – such as Parkinson’s disease or multiple sclerosis

Initially, non-surgical treatment like muscle stimulation is recommended. Training and exercising these muscles can enhance their strength. MStim Reha LGT-231 delivers a low-frequency electric pulse through pads attached to your skin to stimulate contractions of the pelvic floor muscles, which can help strengthen the pelvic floor muscles. You will find it really beneficial if you are unable to contract your pelvic floor muscles.

 Treat Dysphagia 

Dysphagia or difficulty swallowing is a common symptom resulting from neurological injuries or diseases. Mim Reha LGT-231 is a specialized medical device assisting in neurological rehabilitation and making the swallowing process easier.

How does it treat dysphagia?

LGT-231 is an electrotherapy device. It works by delivering neuromuscular electrical stimulation to the muscles associated with swallowing. Using this unit along with other rehabilitation exercises can help reduce rehabilitation time and improve outcomes. 



1. What is TENS, NEMS?

TENS is transcutaneous electrical nerve stimulation and it is non-invasive electrotherapy main for pain relief. NMES is neuromuscular electrical stimulation that directly stimulates surrounding motor nerves and causes muscle contraction.

2. How many treatment sessions could cure the indications?

It varies from the severity of the patient and should be confirmed by the professional therapist.
