The description details a simple electrical muscle stimulation device with fixed electrode placement and no mention of adaptive algorithms or data processing that would indicate AI/ML.
No.
The intended use is "Strengthening, toning and firming of the bottom and thigh region," which is not a therapeutic purpose.
No
Explanation: The device is described as a muscle stimulation system intended for strengthening, toning, and firming muscles. Its purpose is to exercise muscles, not to diagnose medical conditions or provide diagnostic information.
No
The device description clearly outlines hardware components including an electronic stimulator module, shorts garment with integral electrodes, adhesive electrodes, batteries, and a carry pouch. It is a physical muscle stimulation system, not software only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is "Strengthening, toning and firming of the bottom and thigh region." This describes a physical effect on the body, not a diagnostic test performed on samples taken from the body.
- Device Description: The device is a muscle stimulation system that applies electrical signals to the skin to exercise muscles. This is a therapeutic or cosmetic device, not a diagnostic one.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting diseases or conditions, or providing diagnostic information.
IVD devices are specifically designed to perform tests on samples from the human body to provide information for the diagnosis, monitoring, or treatment of diseases or conditions. This device does not fit that description.

Device Description
Slendertone Flex Bottom and thigh toning system is a two- channel battery operated muscle stimulation system specifically designed to exercise the bottom and thigh muscles. It comprises two main components, namely, an electronic stimulator module which generates the required stimulation signals, and a shorts garment with integral electrodes, which connects the signals from the stimulator to the skin. The electrodes are located on the inner surface of the shorts. In effect, the shorts in this case take the place of the lead wires commonly found in most conventional muscle stimulators.
The product is supplied with a set of double- sided adhesive electrodes, an instruction manual, a set of batteries, and a carry pouch. Power is derived from three LRO3 cells located in a compartment protected by a removable battery cover.
Although a two- channel system, there are six electrodes. The electrodes connect adhesively to studs on the inner surface of the shorts. The garment is worn as shorts. with the leg openings and waist secured by Velcro fastening patches. When the shorts are on the body two electrodes (1each side) are located over the gluteal muscles. placed horizontally in the midline of the buttock and the larger two (one at the back of each leg) over the hamstring muscles. Two electrodes are located on either side of the top of the front of the thighs following the linguinal line to act on the quadriceps muscles.
There is no current passed from side to side. Because the user has no access to the wiring or connectors within the shorts, he/she cannot alter the current path and so the possibilities for mis-use are greatly reduced.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
BMR conducted a prospective, controlled, single blind, stratified, randomised study with 60 female volunteers to measure the effects of a program of EMS on the bottom and thigh muscles over an eight week period, using the electrode positions and stimulation parameters of the Slendertone FLEX Bottom & Thigh Toning system. The study was designed and carried out by BMR at its consumer research centre in Galway, Ireland.
In psychometric tests, the treated group in the study reported a marked improvement in firmness compared to the control group over the period of the study. Moreover, the treated group showed improvements in self-image and well - being. The control group did not report such an improvement.
In objective measurements of isokinetic and isometric muscle strength, the treated group showed average increases in muscle strength of 11% (extension torque at 15 ' and 38.1% (Flexion torque at 15'), this improvement continued throughout the study duration.
While marginal improvements shown by the control group were initially observed, this was rationalised as being the result of learning effect and improvement had stabilised by week 4 of the study.
When the Full 8 week study had been completed very large differences were observed between the treatment and control groups in terms of muscle strength.
Weight changes were controlled and pre and post measurements indicated that the treatment group did not change in weight .

ട Intended Use
The Slendertone Flex Bottom and thigh toning device is intended for use by healthy persons to apply trans-cutaneous electrical muscle stimulation (EMS) through skin contact electrodes for the following purposes;
- Improvement of muscle tone to the bottom and thighs. .
- Strengthening of the muscles in the bottom and thighs, specifically the ● quadriceps and hamstrings.

Technological Comparison 6
The Slendertone FLEX Bottom and Thigh Toning System is the same as the Slendertone FLEX Abdominal training system in it's delivery of the stimulation signal and has similar parameter setting. There are similar restrictions between the two devices in that electrode positioning is governed by and integral to the garment. Both products utilise a LCD screen with user compliance logging.
Non clinical Tests
Comparisons of electrical outputs for the two devices show similar results. They have both been designed and independently tested to the following requirements;

When the Full 8 week study had been completed very large differences were observed between the treatment and control groups in terms of muscle strength.
Weight changes were controlled and pre and post measurements indicated that the treatment group did not change in weight .
ന Test Conclusions
Testing of the stimulation output parameters of the Slendertone Flex Bottom & Thigh toning device indicates that it is safe, and that it provides appropriate stimulation output for the bottom & thigh muscle groups. The controlled study indicates that users experience a significant improvement in muscle tone, strength and muscle firmness.
