According to MMG parameters that are sensed and/or recorded, a stimulation session may be adjusted (e.g., intensity of stimulation and/or other stimulation parameters) accordingly.

Collected data, processed or raw, may be transmitted to the mobile device. In some instances, data regarding the stimulation session that had been implemented may be recorded or tracked. For example parameters regarding the stimulation may be recorded, e. g. by the processing unit of the central body. In some instances, a stimulation length, stimulation intensity, stimulation session , or other ters such as stimulation frequencies for ctions and rest periods, pulse widths, duty cycle parameters, ramp up values, ramp down , burst pulse parameters, stimulation intensity, waveform shape, or interphase interval, etc may be recorded. In some instances, data from the sensor system may be recorded or tracked.

The recorded or tracked data may be conﬁgured to be itted to the mobile device, e. g. using a ss communication channel. ted data, processed or raw, may be transmitted to a server.

The central body may be designed to minimize obtrusiveness such that it can be coupled to the user and be forgotten. As such, the aforementioned small profile, simple interface, ability to be used in conjunction with the mobile device, and/or integration of the sensor system may be of advantage. For example, the l body may be coupled to the user mically and unobtrusively via adhesives or straps. The user may ent stimulation sessions via the mobile device which is used in everyday life while the small EMS device performs the _ 28 _ stimulation unobtrusively (e.g., under the user’s clothes). The user may interact with the EMS device when necessary via the simple interface. The EMS device may further e various additional functionalities to the EMS device with an integrated sensor system without need for additional attachments such that the EMS device remains simple to use and unobtrusive.

The set of EMS devices may be programmed, or otherwise red to implement one or more stimulation sessions. In some instances, the set of EMS devices may together implement a single stimulation session. For example, the master device 402 may receive a set of ctions from a mobile device 420. A processing unit of the master device may e the set of instructions and may further transmit (e.g., broadcast) the set of instructions, or relevant _ 31 _ parts of the instructions, to the slave devices.
