Participant Flow

Single group cohort study with random serial allocation of treatment type. All participants underwent each of the three stimulation conditions (TENS, t-NMES, no stimulation) three times in a computer-generated random sequence for each outcome measure with a 5-minute wash-out period between each stimulation.

TENS/t-NMES/No Stimulation
n=10 Participants
Electrical Stimulation-TENS: TENS stimulation parameters were of a symmetric waveform, a frequency of 100 Hz, and a pulse duration of 300 microseconds (EMPI 300PVTM program PPR #7) applied for 10 seconds. Electrical Stimulation-t-NMES: t-NMES parameters were a symmetric waveform with 2 second ramp-up and 2 second ramp-down, a frequency of 35Hz, and a pulse duration of 300 microseconds (EMPI 300PVTM program PPR #3). The t-NMES current intensity was set by adjusting the amplitude to yield the strongest contraction of the underlying muscles without initiating pain. No stimulation: Device and electrodes remained in place but no stimulation was delivered over the 10 second interval. Exposed to each stimulation 3 times for each shoulder ROM.
