Study summary

The goal of this clinical trial is to evaluate the effect of Transfer of Energy Capacitive and Resistive (TECAR) on pain, functional disability and electrophysiological parameters in adults with chronic discogenic sciatica . The main questions it aims to answer are:

  • Is there significant effect of TECAR therapy on pain, functional disability and Electrophysiological parameters (H-reflex latency and amplitude) ? Researchers will compare effect of adding TECAR therapy to conventional physical therapy program (TENS, hot pack, stretching exercises and core stability exercises) Vs conventional physical therapy program alone to see if there is a beneficial effect of adding TECAR therapy to physical therapy program Participants in study group will receive TECAR therapy in addition to conventional PT program while participants in control group will receive conventional PT program

  • Symptom duration more than 3 months
  • Pain score ≥ 4 on the Visual Analogue Scale (VAS)
  • Ability to participate in outpatient physiotherapy

Exclusion criteria

Exclusion Criteria:

  • Previous lumbar spine surgery
  • Pacemaker or metallic implants
  • Peripheral neuropathy or systemic neurological disorders
  • Severe sensory loss
  • Skin lesions at the treatment site
  • Recent injection (\< 3 weeks)
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Interventions

  • DeviceTransfer of Energy Capacitive and Resistive (TECAR) therapy

    * The participant lies prone or side-lying depending on comfort. * Conductive cream is applied to the lumbar region (L4-S1) and gluteal area. * Capacitive mode (CET) will be applied first to target superficial soft tissues. * Resistive mode (RET) will follow to target deeper structures including paraspinal muscles, facet joints, and nerve root pathway. * Each mode will be applied for a predetermined duration (e.g., 10 minutes CET + 10 minutes RET). * Intensity adjusted to produce a deep warm sensation without discomfort. * Total session duration: \~20 minutes treatment program will be delivered in manner of 3 sessions per week for four weeks.

    conventional physical therapy program will include TENS, hot pack, stretching exercises and core stabilization exercises for 3 sessions per week for four weeks.

What researchers measure

Primary outcomes

  1. Pain intensity

    lower back pain will be assessed though Visual Analogue Scale (VAS) which is used to measure the severity of pain. It is a straight line with one end representing no pain and the other end representing the worst imaginable pain. The subject will mark a point on the line that corresponds to the current level of pain he or she experiences. Higher values indicate higher levels of pain while lower values indicate lower levels of pain

    Time frame: from enrollment to the end of treatment at 4 weeks

Secondary outcomes

  1. Hoffmann reflex (H-reflex)

    H-reflex has been measured in the soleus muscle by stimulating the tibial nerve with a one-millisecond pulse at 0.2pps of H-max. The peak-to-peak amplitude of the highest recorded H-reflex and the latencies of four spaced traces for both lower extremities will be averaged for each participant. lower amplitudes and delayed latencies indicate more damage to nerve root, while higher amplitudes and shorter latencies indicate less damage

    Time frame: from enrollment to the end of treatment at 4 weeks

  2. functional disability

    Functional disability will be evaluated using the Oswestry Disability Index (ODI), which is considered the gold standard for assessing disability in low back pain and radiculopathy. The ODI consists of 10 sections evaluating daily activities such as lifting, walking, sitting, and personal care. It is scored from 0% to 100%, where higher percentages represent more severe functional impairment

    Time frame: from enrollment to the end of treatment at 4 weeks
