TENS uses low-voltage electrical currents delivered via skin electrodes to modulate pain signals and promote analgesia. It is a non-invasive adjunct commonly used for acute and chronic musculoskeletal pain management. At Back To Life, TENS is applied by clinicians as part of a multimodal plan — combined with physical therapy, manual therapy and targeted exercise.
TENS works via gate-control mechanisms (activating large diameter afferents to inhibit nociceptive transmission) and by promoting endogenous opioid release with certain frequency/intensity settings. Parameter selection depends on pain type and clinical goals.
Post-operative pain adjunct, acute soft tissue pain, and short-term flare-ups.
Chronic low back pain, osteoarthritic pain, neuropathic syndromes (selected cases as per clinician judgement).
Used to enable early mobilization by providing symptomatic relief during exercise.
TENS is generally safe when used appropriately. It is contraindicated for patients with implanted electronic devices (e.g., pacemakers), over the eyes, across the chest of pregnant women, or on broken skin. Clinician screening is mandatory.
TENS provides symptomatic relief for many patients but is rarely a standalone cure. Best results occur when combined with active rehabilitation and targeted treatments addressing pain drivers.
Home TENS units exist; however, clinicians should provide guidance on electrode placement, parameters and safety before home use.
