Targeted Support for Quadriceps Recovery
The MediStim XP / PolyStim XP is a premium, portable dual-channel stimulation system designed to support professional neuromuscular rehabilitation in clinic or at home.
Following knee injury or surgery, the quadriceps can become significantly weakened and difficult to activate — sometimes even when you are actively trying to contract the muscle. Restoring effective quadriceps activation and strength is therefore an important part of many knee rehabilitation programmes.
Using NMES (Neuromuscular Electrical Stimulation), carefully controlled electrical impulses stimulate the motor nerves supplying the quadriceps, producing visible, controlled muscle contractions and helping support muscle activation, neuromuscular re-education and progressive strengthening.
Whether rehabilitation follows ACL reconstruction, total or partial knee replacement, other knee surgery, injury or a period of reduced mobility, NMES can provide valuable support alongside your prescribed rehabilitation programme.
How It Supports Your Rehabilitation
- Early quadriceps activation — stimulates controlled quadriceps contractions when voluntary activation may be reduced following injury, surgery or immobilisation, allowing recovery to start earlier, and minimising post-surgery muscle atrophy.
- Neuromuscular re-education — helps re-establish effective recruitment of the quadriceps and supports the return of voluntary muscle control
- Helps combat disuse muscle atrophy — stimulates muscle contractions during periods of reduced activity, helping maintain and rebuild muscle condition
- Quadriceps strengthening — supports progressive rebuilding of quadriceps strength alongside physiotherapy and active exercise
- VMO & medial quadriceps activation — electrode positioning can provide targeted stimulation across the medial quadriceps as part of a wider quadriceps rehabilitation programme
- Supports knee stability & function — stronger, better-functioning quadriceps play an important role in knee control, stability and everyday functional movement
- Supports post-operative rehabilitation — particularly useful where quadriceps weakness or inhibition occurs following procedures such as ACL reconstruction, total knee replacement (TKR) and partial knee replacement (PKR)
- Supports rehabilitation after injury or immobilisation — helps activate muscles that have weakened following reduced weight-bearing, bracing or periods of inactivity
- Progressive muscle conditioning — complements active rehabilitation as strength improves, supporting repeated muscle contractions and progressive conditioning
- Return to activity & sport — supports rebuilding the quadriceps strength and muscular function required for walking, stairs, exercise and progression towards sporting activity
- Improved local circulation — repeated muscular contractions support local blood circulation within the stimulated area
- Simple pre-set programmes — clinically designed stimulation parameters provide straightforward treatment without complicated programming or setup
Why Quadriceps Activation Matters
After knee injury or surgery, weakness is not always simply the result of losing muscle.
Pain, swelling and changes around the knee can interfere with the nervous system’s ability to recruit the quadriceps effectively — often described clinically as quadriceps inhibition or arthrogenic muscle inhibition (AMI).
This can make the quadriceps feel as though it simply will not “switch on”, even when you are actively trying to contract it.
NMES provides an external stimulus to the neuromuscular system, helping produce a controlled quadriceps contraction while voluntary activation is limited. As rehabilitation progresses, stimulation can be used alongside active contractions and prescribed exercise to support the transition towards stronger voluntary muscle function.
From Early Activation to Progressive Strengthening
Quadriceps rehabilitation changes as you recover. The MediStim XP / PolyStim XP has been designed to support different stages of neuromuscular rehabilitation rather than providing a single fixed stimulation pattern.
Early Rehabilitation
Support muscle activation and neuromuscular re-education when achieving a strong voluntary quadriceps contraction is difficult.
Rebuilding Muscle
Support the quadriceps during periods of weakness or disuse and complement your prescribed strengthening programme.
Progressive Strengthening
As voluntary control improves, stimulation can be incorporated alongside active exercise to support stronger muscular contractions and progressive conditioning.
Return to Function
Support the rebuilding of quadriceps strength and control required for everyday movement, exercise and progression towards normal activity.
Professional Rehabilitation — At Home
The same advanced stimulation platform designed to support professional clinical rehabilitation can also be used conveniently at home, helping your rehabilitation continue between physiotherapy appointments.
Compact, portable and straightforward to operate, the MediStim XP / PolyStim XP provides access to professional-quality neuromuscular stimulation wherever your rehabilitation takes place.
