Effect of pulsed short-wave diathermy on pain and function of subjects with osteoarthritis of the knee: a placebo-controlled double-blind clinical trial
ABSTRACT To examine the effects of pulsed short-wave diathermy (PSWD), delivered at an intensity sufficient to induce a thermal sensation and at an athermal intensity, in comparison with a placebo short-wave diathermy treatment, on reported pain, stiffness and functional ability and on mobility performance of patients with osteoarthritis of the knee.
A placebo-controlled double-blind trial with sequential allocation of patients to different treatment groups.
Outpatient physiotherapy department.
One hundred and three consecutive patients, mean age 73.7 (+/-6.6) years with osteoarthritis of one or both knees for at least three months.
All participants received three 20-min-long treatments per week for three weeks. One group received PSWD with mean power of 18 W (thermal effect), one group received PSWD with mean power of 1.8 W (athermal effect), and one group received sham short-wave diathermy treatment. Patients were assessed before the initial treatment, immediately following the last treatment, and at a three-month follow-up.
Outcome measures included the WOMAC Osteoarthritis Index, which assessed reported pain, stiffness, and functional ability, and four measures of mobility performance: Timed Get Up and Go test (TGUG), stair-climbing, stair, descending and a 3-min walk.
A difference across time was observed for the pain and stiffness categories of the WOMAC Osteoarthritis Index (p = 0.033 and p = 0.008, respectively), with no differences between groups. No other significant differences across time or between groups were observed in any of the other measures.
The findings do not demonstrate pulsed short-wave diathermy, as it is utilized in clinical settings, to be effective in the treatment of osteoarthritis of the knee.

ABSTRACT: Amaç: Bu çalışmanın amacı; diz osteoartriti (OA) olan hastalarda farklı fizik tedavi kombinasyonlarına ilave edilen bisiklet egzersizlerinin; ağrı, fonksiyonel durum ve yaşam kalitesine katkısının olup olmadığını araştırmaktır. Gereç ve Yöntem: 80 diz OA'li hasta rastgele yöntemle dört gruba ayrılarak; 1. gruba sıcak paket + transkutanöz elektriksel sinir stimülasyonu (TENS) + ultrason, 2. gruba sıcak paket + TENS + kesikli kısa dalga diatermi (KDD), 3. gruba sıcak paket + TENS + ultrason + bisiklet egzersizi, 4. gruba ise sıcak paket + TENS + kesikli KDD + bisiklet egzersizi uygulandı. Tedavi programı 3 hafta süreyle uygulandı. Hastalar; ağrı, 50 adım yürüme süresi ve eklem hareket açıklığı ile değerlendirildiler. Bulgular: Tedavi bitiminde grupların hepsinde istatistiksel olarak anlamlı düzelme görüldü. Bisiklet egzersizlerinin uygulandığı 3. ve 4. grupta ağrı ve 50 adım yürüme süresi istatistiksel olarak anlamlı düzeyde diğer gruplardan daha iyiydi. Sonuç: Bisiklet egzersizleri ile birlikte uygulanan fizik tedavi kombinasyonlarının tek başına uygulanan fizik tedavi kombinasyonlarından daha etkili olduğu sonucuna varıldı. The Efficacy of Ultrasound, Pulsed Shortwave Diathermy and Bicycle Exercises in Knee Osteoarthritis Objective: The purpose of this study is to investigate if the bicycle exercises being addition to different physical therapy combinations have effects on pain, functional capacity and quality of life in the patients with knee osteoarthritis (OA). Materials and Methods: 80 patients with knee OA were randomly divided into four groups and applied hot pack (HP) + transkutanoz elektrikil neurol stimulastion (TENS) + ultrasound (US) to the first group, HP + TENS + Pulsed shortwave diathermy (PSWD) to the second group, HP + TENS + US + bicycle exercises to the third group and HP + TENS + Pulsed SWD + bicycle exercises to the fourth group. These therapy programs were applied for 3 weeks. Patients were evaluated with pain, the duration of 50 steps walking, and range of motion. Results: Statistically significant improvement was observed all groups at the end of the therapy. The patients in groups who were subjected to bicycle exercises (Groups 3 and 4) were siginficantly better in terms of the decrease in pain and the duration of 50 steps walking than the other groups. Conclusion: Physical therapy combinations involving bicycle exercises were found out to be more efficient than single physical therapy combinations.
