After surgery
- After knee replacement or ACL surgery
- When a muscle is hard to activate
- Alongside a physiotherapy programme
Neuromuscular re-education
Electrical muscle stimulation (EMS) uses small electrical pulses through pads on the skin to make muscles contract. It can help weak muscles work again after injury, surgery or long inactivity. At Mitogenez it supports exercise and rehab in a doctor-led plan; it never replaces them.

The idea
After surgery, injury or a long period of inactivity, some muscles become hard to activate. After a knee operation, for example, the thigh muscle can seem to switch off. EMS gives the muscle a gentle electrical signal so it contracts. This can help keep it working while you rebuild strength with exercise.
How it works
Sticky pads are placed over the target muscles, such as the thigh, and connected to a stimulator.
Small pulses make the muscle tighten and relax. The strength is set to a level that is firm but comfortable.
EMS is combined with active exercise, which is what builds lasting strength and control.
Your session
Session length
Typically 20–30 minutes
How it feels
Tingling and firm muscle tightening; intensity is adjusted to your comfort
Course
A series of sessions, set and reviewed by your doctor
Before you start
A doctor screens you for safety
Who it may help
Evidence is strongest for supporting thigh muscle strength after knee surgery, used alongside exercise. For age-related muscle loss, results are encouraging but still developing. Your doctor will tell you honestly whether EMS is likely to help you.
Where it fits
EMS is a supportive tool, not a shortcut. Your doctor first finds out why a muscle is weak, then builds a plan around exercise and rehab. EMS is added where a muscle needs help to switch on or where hard exercise is not yet possible, and your strength is rechecked as you progress.
Assess
A doctor reviews your health and screens you for safety.
Plan
Medicine and lifestyle first; therapies only where they help.
Measure
Retests show what is working, and the plan adapts.
Safety first
Questions
It may. After knee surgery, the thigh muscle often becomes hard to activate. Studies suggest EMS, added to standard rehab, can help thigh strength in the early weeks. It works alongside physiotherapy, not instead of it.
For many people, yes, after a doctor’s screening. EMS can make muscles work without heavy weights. Results for age-related muscle loss are encouraging but still developing, and it works best combined with exercise and enough protein.
It depends on your goal. After surgery, some people notice it is easier to tighten the muscle within a few weeks. Building muscle takes longer, usually a few months of regular exercise. Your doctor tracks your progress rather than assuming it.
When screened and supervised, EMS is generally safe. It is not suitable if you have a pacemaker or other implanted electronic device, are pregnant, have poorly controlled epilepsy or a recent blood clot. Mild skin redness or soreness is the most common effect.
Usually a course of sessions over several weeks, often alongside physiotherapy. Your doctor sets the plan, reviews how you respond, and adjusts it.

A doctor looks at your whole health first, then decides with you whether EMS belongs in your plan.
