In some aspects, ments of the present disclosure may comprise l actuatable ism. In some aspects, ments of the present disclosure may comprise 2 actuatable mechanisms, 3 actuatable mechanisms, 4 able mechanisms, or 5 or more actuatable mechanisms. For example, an electrical stimulation device as disclosed herein may comprise l actuatable In some embodiments, the actuatable mechanism may be a depressible mechanism 1105, such as button or micro-switch. In other embodiments, the actuatable mechanism may be a slidable or ble ism. In some embodiments comprising two or more able mechanisms, each actuatable mechanism may be separately selected from the group consisting of depressible mechanisms, slidable mechanisms, and rotatable mechanisms.

In another example, ion of the actuatable ism may cause an electrical stimulation device to switch from an off state to executing a ﬁrst stimulation 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 sed herein may comprise a depressible mechanism, and actuation of the depressible mechanism may cause the pulse width to increase. In another example, an electrical ation device as disclosed herein may comprise a ble mechanism, and rotation of the rotatable mechanism may cause the stimulation frequency to increase.

In another example, a paused stimulation session may be resumed by depressing a depressible mechanism for 1-2 seconds. In yet another e, an ical ation device may comprise a depressible mechanism, and depression of the sible 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, depending on the degree of the input.

In one example, an actuatable ism may be programmed, or otherwise conﬁgured to affect the state of the stimulation in 4 or more different ways, wherein the 4 or more different ways comprise pausing of the stimulation program, resuming of the stimulation program, 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 modalities, and thereby improve the efﬁciency of the stimulation.
