TENS and EMS combo unit; Twin Stim® 2nd Edition; Dual Channel

The Twin Stim 2nd Edition Digital TENS & EMS Combo is a portable, easy-to-use device, combining TENS (Transcutaneous Electrical Nerve Stimulation) with EMS (Electrical Muscle Stimulation) electrotherapy, allowing many options to address pain.

Product Features

• Relieve your pain by using the TENS Mode.
  • TENS is a non-invasive, drug free method to control your pain by sending tiny electrical impulses through the skin to target the nerves. In many cases, this stimulation will greatly reduce or eliminate pain.
• Strengthen your muscles by using the EMS Mode.
  • EMS is widely used in hospitals and sports clinics to treat muscle injuries, to re-educate paralyzed muscles, and to prevent atrophy in affected muscles.
• Channels: Dual Channel
• Pulse Amplitude: Adjustable, 0-100 mA
• Voltage: 0 – 50V (Load: 500 ohm)
• Pulse Rate: Adjustable, from 2 to 150 Hz, 1 Hz/step
• Pulse Width: Adjustable, from 50 to 300 microseconds, 10µS/step
• Wave Form: Asymmetrical Bi-Phasic Square Pulse
• On Time: Adjustable, 2~90 seconds, 1 Sec./ step
• Off Time: Adjustable, 2~90 seconds, 1 Sec./ step
• Ramp Time: Adjustable, 1~8 seconds, 1 Sec./ step, The “On” time will increase and decrease in the setting value.
• Patient Compliance Meter: This unit can store 60 sets of operation records. Total recorded time is 999 hours
• Timer: Adjustable, from 5 to 60 minutes or Continuous. Adjustable in 5 minutes each step. Treatment time counts down automatically
• Package comes with everything you need to start treatment right away.

Product Specifications:

• 2 EMS Modes:
  • Synchronous: Stimulation of both channels occurs synchronously. The “ON” time including “Ramp Up” and “Ramp Down” time. Therefore, the setting of ON Time should be no less than two times of the “Ramp” time in this mode. ON TIME Ramp up + Ramp down
  • Alternate: The stimulation of CH2 will occur after the 1st contraction of CH1 is completed. In this mode, the setting of ON Time should be no less than two times of the “Ramp” time. The OFF Time should be equal to, or more than, the ON Time. ON TIME Ramp up + Ramp down OFF TIME ON.
• 5 TENS Modes:
  • Burst Mode (B): Burst rate: Adjustable, 0-5 5Hz; Pulse width adjustable, 50~300uS; Frequency fixed = 100 Hz
  • Normal Mode (N): The pulse rate and pulse width are adjustable. It generates continuous stimulation based on the setting value.
  • Modulation (M) mode is a combination of pulse rate and pulse width modulation. The pulse rate and width are automatically varied in a cycle pattern. The pulse width is decreased by 50% from its original setting in 0.5 second, then the pulse rate is decreased by 50% from its original setting in 0.5 second. Total cycle time is 1 second. In this mode, pulse rate(2-150Hz) and pulse width(50-300S) are fully adjustable.
  • The SD1 (Strength-Duration) mode consists of automatic modulation intensity and pulse width in 40% range. The intensity is always increasing while the pulse width is decreasing and vice-versa. The intensity is decreased by 40% while the pulse width is increased by 40% in 5 seconds. In the next 5 seconds, the intensity is increased by 40% while the pulse width is decreased by 40%. Total cycle time is 10 seconds. Pulse rate (from 2~150Hz) and pulse width (from 50~300S) are fully adjustable.
  • The SD2 (Strength-Duration) mode consists of automatic modulation intensity and pulse width in 70% range. The intensity is always increasing while the pulse width is decreasing and vice-versa. The intensity is decreased by 70% while the pulse width is increased by 70% in 5 seconds. In the next 5 seconds, the intensity is increased by 70% while the pulse width is decreased by 70%. Total cycle time is 10 seconds. Pulse rate (from 2~150Hz) and pulse width (from 50~300S) are fully adjustable.
