Superfast is a Neurotherapy (LMNT) leg treatment for sharp pain in the groin or waist after the leg has suddenly slipped. It is given lying down, with the therapist's soft soles along the leg — and always on the leg opposite the painful side.
Overview
What is Superfast?
When a leg suddenly slips — on a wet floor, a stair or uneven ground — the muscles of one side can be wrenched over towards the other side. The result is a sharp pain in the groin, where the thigh meets the body, or in the waist. Superfast was found to give quick relief in exactly this situation.
The name is one of the therapy's 'action' names, like Rocket and Hammering: it describes how quickly the relief comes, not a body part. It is a physical point — it works on muscles, not on glands.
Its most surprising feature is the side. Whichever side the pain is on, Superfast is given on the other leg. This follows the therapy's Opposite Point rule: the place to treat is sometimes the partner of the place that hurts.

Where it is given
Where is Superfast given?
PositionLying on the back
Body areaThe leg opposite the pain — inner side from thigh to ankle, then outer thigh and calf
You lie down, and the treatment is given on the leg opposite the painful side. It covers the inner side of that leg from the thigh down to the ankle, and the outer side of the thigh and calf.
Partway through, the knee is turned over and two or three pillows are placed under it for support, so that the outer side of the leg can be reached. The pillows are part of the treatment and are never skipped.

How it is given
How is Superfast given?
Superfast is given with the soft middle part of both the therapist's soles, in close, overlapping steps that press and draw the leg muscles along their length. The therapist's weight is carried on his own arms, so only gentle, controlled pressure comes down on the leg.
It should feel like a firm, smooth pressure travelling along the leg, never a jab. The direction of each part and how many rounds are given are taught hands-on in the course, under a trained teacher.

What it does
What does Superfast do in the body?
Neurotherapy (LMNT) teaching explains a slip as the muscles of one side going over to the other side, and Superfast as the treatment that draws them back, giving considerable relief. Body science confirms that a slip commonly strains the inner-thigh muscles at the groin, and that the two legs are tightly linked through shared reflexes in the spinal cord; how a treatment on the other leg eases the pain is the therapy's own finding from practice.
Eases sharp groin pain after a sudden slip of the leg.
Eases sharp waist pain from the same kind of slip.
Works on the leg muscles — inner and outer — of the opposite leg, so the painful side is not touched while it is fresh.
Organs it reaches
Muscles — The leg muscles, inner and outer, that the soles press and draw.
Joints — The hip joint at the groin, where a slip wrenches the muscles.
Spinal cord — Reflex circuits in the spinal cord link the two legs, so that one side responds to the other.
Its family
Which treatments are close to Superfast?
Superfast belongs to the treatments found one at a time, for one problem each.
Opposite Point — The rule behind it: right hand pairs with left leg, left leg with right hand — and Superfast applies the cross-over idea to a fresh leg strain.
Paralysis Clockwise — Also travels down the inside of the limb and back up the outside — but for a limb weakened by stroke.
Rocket Point — A sister treatment for a blow to the shoulder or arm, when the arm cannot be raised.
Sciatica Setting — Another leg treatment, for pain that runs down the leg from the back.
What it is used for
What is Superfast used for?
Superfast has one clear use: the fresh, sharp pain after a leg has slipped — once a fracture, hernia or emergency has been ruled out.
In an older person, even a small slip can break the hip. A leg that cannot take weight, or lies short and turned outward, goes to hospital — it is not treated on a mat. Osteoporosis
In a man, sudden pain in the groin or scrotum can be an emergency measured in hours. Send for medical help at once. How to tell a patient to see a doctor
My right groin hurts. Why is my left leg being treated?
Because Superfast is always given on the side opposite the pain. This is the therapy's cross-over rule, and it also spares the freshly strained side.
Why are pillows placed under my knee?
So that the outer side of the leg can be reached comfortably while your knee is supported. The pillows are part of the treatment.
I am elderly and slipped yesterday. Should I take Superfast?
First make sure nothing is broken. If you cannot put weight on the leg, or it looks shorter or turned outward, go to hospital. Superfast is only for a strain once a fracture has been ruled out.
Surprising facts
1The inner thigh takes the hit
Most groin strains involve the adductors — the inner-thigh muscles that pull the legs together. A sudden sideways slide of the foot stretches them violently.

2The two legs talk to each other
When you step on something sharp, one leg bends away while the other straightens to hold you up. This crossed reflex is wired in the spinal cord, linking the two legs without waiting for the brain.

3A broken hip has a tell-tale look
After a fall, a leg that looks shorter and rolled outward is a classic sign of a broken hip — one reason an older person's slip is checked before any treatment.
