Study Notes
Transcutaneous Electrical Nerve Stimulation (TENS) Therapy: Parameters and Physiological Effects
- TENS therapy offers slow onset and long duration of analgesia, with different modes and parameters for sensory, motor, and pain modulation purposes.
- TENS modes include Conventional-Highfrequency, Acupuncture-Lowe frequency, and Motor TENS, with specific frequency, pulse duration, and intensity settings for each mode.
- TENS also includes Brief-intense TENS and Burst-TENS modes, each with distinct frequency, pulse duration, and intensity settings for pain modulation and treatment time.
- TENS stimulates nerve fibers, such as Aβ, Aδ, and C fibers, leading to different onset and duration of analgesia, making it suitable for acute/postoperative and chronic pain.
- TENS therapy induces physiological responses at cellular, tissue, segmental, and systematic levels, including effects on nerve cells, muscle contraction, tissue regeneration, and pain control.
- The physiological effects of TENS include analgesic effects, modification of joint mobility, and alteration of microvascular circulation.
- TENS exerts its pain reduction effects through the Gate control theory, modulating pain conducted through Aδ and C fibers, with distinct effects for different types of pain.
- TENS usage spans a wide range of applications, including acute or chronic pain management, myofascial pain, musculoskeletal disorders, and neurological pain.
- TENS therapy has recent applications in muscle strength improvement, wound healing, and fracture healing (non-united fracture), expanding its potential benefits.
- Contraindications for TENS therapy include pregnancy, carotid sinuses, anterior neck, sensory impairment, arterial disease, deep vein thrombosis, and infective conditions.
- TENS should not be used in patients with pacemakers or Implanted Cardioverter-Defibrillators (ICDs) due to the risk of electronic interference with these devices.
- TENS therapy is a versatile and effective modality for pain management, with specific parameters, physiological effects, and wide-ranging applications, but it requires careful consideration of contraindications for safe use.
