Quick Answer
Electrotherapy uses modalities such as TENS, ultrasound and electrical stimulation to relieve pain, reduce muscle spasm and support healing. It is a useful adjunct in physiotherapy but is most effective when combined with manual therapy and exercise — not used alone. Your physiotherapist selects modalities based on your specific condition.
Electrotherapy refers to a range of treatments that use electrical energy, sound waves or currents to relieve pain and support healing. Used appropriately, it complements the core of physiotherapy — assessment, manual therapy and exercise.
Common modalities
Different modalities serve different purposes.
- TENS: reduces pain by stimulating nerves
- Therapeutic ultrasound: may support soft-tissue healing
- Electrical muscle stimulation: helps activate weak muscles
- Interferential therapy: pain relief for deeper tissues
- Heat and cold: manage pain and inflammation
What electrotherapy can and can't do
Electrotherapy can provide helpful short-term pain relief and support certain phases of recovery. However, it does not replace the active rehabilitation — strengthening and movement retraining — that produces lasting change. Beware any clinic that offers only machines.
How we use it at PainFix
We use electrotherapy selectively, as one tool within a comprehensive, personalized plan. This ensures you get symptom relief while also addressing the underlying cause through active treatment.
