项目介绍
低频电刺激（TENS）在一般公立医院参考费用约¥15-40，三甲医院参考费用约¥20-50，常用于相关诊断评估与就医安排，费用随医院及地区有所差异。
主要用途
Primary clinical uses include: short-term management of acute and chronic pain (e.g., low back pain, osteoarthritis, postoperative pain, neuropathic pain); adjunctive therapy in physical rehabilitation to reduce pain-related inhibition of movement; symptomatic relief in fibromyalgia and myofascial pain syndrome; and non-pharmacologic support in palliative care. It is not curative but aims to modulate pain perception via gate control theory and endogenous opioid release.
正常值范围
TENS (Transcutaneous Electrical Nerve Stimulation) is not a diagnostic laboratory test with quantitative 'values' or numerical reference ranges. It is a non-invasive therapeutic modality that delivers low-voltage electrical currents via surface electrodes. Parameters such as frequency (typically 1–150 Hz), pulse width (10–500 μs), intensity (mA, adjusted to patient tolerance), and duration (15–60 minutes per session) are individually titrated—not standardized across populations. There is no universal 'normal range' for TENS; clinical efficacy is determined by symptom relief and tolerability, not numeric thresholds.
偏低可能原因
TENS does not produce measurable 'low values' in the conventional sense. However, subtherapeutic outcomes may result from: inadequate electrode placement, insufficient stimulation intensity (below sensory or motor threshold), device malfunction or battery depletion, poor skin-electrode contact (e.g., due to dry skin or hair), or inappropriate parameter selection (e.g., frequency too low for desired analgesic mechanism).
偏高可能原因
TENS does not yield 'high values' as a diagnostic metric. Adverse or ineffective responses may occur due to: excessive intensity causing discomfort or muscle contraction, excessively high frequency (>100 Hz) leading to nerve fatigue or reduced analgesia, prolonged session duration inducing skin irritation or habituation, improper electrode positioning over contraindicated areas (e.g., carotid sinus, anterior neck), or use in patients with implanted electronic devices (e.g., pacemakers) without medical clearance.
