Conventional Transcutaneous Electrical Nerve Stimulation versus Cryotherapy for Pain Relief in Patients with Total Knee Replacement Surgery: A Comparative Study

Osteoarthritis is a condition in population above 60 years. Total knee replacement surgery is performed for severe Osteoarthritis. Rehabilitation plays an important role post surgery. The aim of the study is to find the effectiveness of Cryotherapy versus Conventional Transcutaneous Electrical Nerve Stimulation (TENS) for pain relief in patients with total knee replacement surgery. A study with total 30 patients were allotted groups by chit method into Group A, B and C which were given Cryotherapy, TENS or TENS and Cryotherapy for 20 minutes for 5 days. Pain was noted on NUMERICAL PAIN RATING SCALE pre treatment, day 3 and day 5. Data was analysed after 5 days post which results was drawn, there is maximum reduction in pain in group given TENS and Cryotherapy with P value less than 0.05. This concludes that combination of TENS and Cryotherapy is better than Cryotherapy or TENS alone.
