Each of the EMS s may be as previously described herein. For example, each of the EMS devices may comprise a low proﬁle, be ergonomic, comprise a simple interface, comprise a sensor system, and/or be used in conjunction with a mobile device. A single mobile device may be in ication with l, 2, 3, 5, 7, 10, , 20, 50, 100, 500, 1000, 2000, 5000, 10000, 20000, 50000, 100000 or more EMS devices.

In some aspects, embodiments of the present disclosure may comprise l actuatable mechanism. In some aspects, embodiments of the present disclosure may comprise 2 actuatable mechanisms, 3 actuatable mechanisms, 4 actuatable mechanisms, or 5 or more able mechanisms. For e, an electrical stimulation device as disclosed herein may comprise l actuatable mechanism.

In some embodiments, the able ism may be a depressible mechanism 1105, such as button or micro-switch. In other ments, the actuatable ism may be a slidable or rotatable mechanism.

In some embodiments, actuation of the one or more actuatable mechanisms may permit the user to cycle between a plurality of different stimulation programs. For example, actuation of _ 49 _ the actuatable mechanism may cause an electrical stimulation device to switch from executing a ﬁrst stimulation program to a second stimulation program. In another example, actuation of the actuatable mechanism may cause an electrical stimulation device to switch from an off state to executing a ﬁrst ation program. In the same example, actuation of the actuatable mechanism a second time may cause the electrical stimulation device to switch from executing a ﬁrst stimulation program to an off state. It should appreciated that an off state in any of the embodiments disclosed herein may refer to an idle state (e.g., wherein the device may be on but the stimulation program is paused) or a powered down state (e.g., wherein the electrical stimulation device is powered off. In some embodiments, actuation of the actuatable mechanism may affect the intensity of the stimulation program. For example, an electrical stimulation device as disclosed herein may comprise a depressible mechanism, and actuation of the depressible mechanism may cause the pulse width to increase. In another e, an electrical stimulation device as disclosed herein may comprise a rotatable mechanism, and rotation of the rotatable mechanism may cause the stimulation frequency to increase.

In an of the embodiments as disclosed herein, an input may comprise actuation of an actuatable mechanism. In one example, an ical stimulation device may comprise a depressible mechanism, and brieﬂy (e.g., less than half of one second) depressing and releasing the depressible mechanism may pause the current stimulation session.

In another example, a paused stimulation n may be resumed by depressing a depressible mechanism for 1-2 seconds. In yet another example, an electrical stimulation device may comprise a depressible mechanism, and depression of the depressible mechanism for greater than 2 seconds may increase the intensity of the current stimulation session. In some embodiments, actuation of the actuatable mechanism may be programmed, or otherwise conﬁgured to affect the state of the stimulation program in one way. In some embodiments, actuation of the actuatable mechanism may be programmed, or otherwise conﬁgured to affect the state of the stimulation m in more than one way, ing on the degree of the input. In some embodiments, _ 50 _ actuation of the able mechanism may be programmed, or otherwise conﬁgured to affect the state of the stimulation program in 2 ways, 3 ways, 4 ways, 5 ways, 6 ways, 7 ways, 8 ways, 9 ways, or 10 or more ways, depending on the degree of the input. In one example comprising an actuatable mechanism programmed, or otherwise conﬁgured to affect the state of the stimulation program in 2 ways, an electrical stimulation device may comprise a depressible mechanism, and brieﬂy (e.g., less than half of one second) depressing and releasing the depressible ism may increase the intensity of the current ation n by one level, whereas sing a depressible mechanism for l-2 seconds may decrease the intensity of the current stimulation session by one level. A person having skill in the art will appreciate that the state of the stimulation program may be affected in a y of ways. Non-limiting examples of ways in which the state of a stimulation program may be affected include pausing of the stimulation program, turning off the ation switching to a different stimulation program, resuming of the stimulation program, increasing of an intensity of the stimulation program, and sing of the intensity of the stimulation program. In one example, an actuatable mechanism may be programmed, or otherwise red to affect the state of the stimulation in 4 or more different ways, wherein the 4 or more different ways comprise pausing of the ation program, resuming of the stimulation m, increasing of an intensity of the stimulation program, and decreasing of the intensity of the stimulation program.

Random modiﬁcation of at least one stimulation parameter between sive stimulation runs, stimulation program phases or levels can prevent muscle adaption to the same electrical stimulation ties, and thereby improve the efﬁciency of the stimulation. For example, random modiﬁcation of at least one stimulation ter may improve fatigue resistance (e.g., endurance). In another example, random modiﬁcation of at least one stimulation parameter may increase force production. illustrates some embodiments of the present sure comprising a method 1200 for stimulating a user comprising a plurality of steps, wherein each step may comprise one or more sub-steps.

In some embodiments, two or more of the plurality of different ation programs may differ in a desired effect (e.g., ent, ﬁtness, performance enhancement, stimulation, etc). Accordingly, the predeﬁned range for a given ation parameter may be different for different stimulation programs. In some embodiments, the predeﬁned ranges may be user conﬁgurable 1209.
