Clinical Trial Summary

The aim of this study was to investigate whether exercise-induced hypoalgesia (EIH) is present following exercise in patient after total knee arthroplasty (TKA) and if so, if it changes with exercise intensity. A repeated measures and single-blinded randomized study were done. Thirty-eight patients 24 hours after TKA were randomly assigned to either low intensity exercises (LIE) group or high intensity exercises (HIE) group. An exercise programs lasted for five days during the hospitalization period. Pain severity was assessed by Visual Analog Scale (VAS) (0-10 mm). Pressure pain thresholds (PPTs) were measured over quadriceps and biceps brachii and muscles immediately before and after exercise.

Description:

Background: The aim of this study was to investigate whether exercise-induced hypoalgesia (EIH) is present following exercise in patient after total knee arthroplasty (TKA) and if so, if it changes with exercise intensity.

Methods : A repeated measures and single-blinded randomized study were done. Thirty-eight patients 24 hours after TKA were randomly assigned to either low intensity exercises (LIE) group or high intensity exercises (HIE) group. An exercise programs lasted for five days during the hospitalization period. Pain severity was assessed by Visual Analog Scale (VAS) (0-10 mm). Pressure pain thresholds (PPTs) were measured over quadriceps and biceps brachii and muscles immediately before and after exercise.

Intervention

Behavioral:
• High Intensity Exercises Program
HIE program consisted of ankle pump exercise, Quadriceps isometric exercise, Terminal extension exercise, Passive-active assistive-active range of motion exercise, Heel sliding exercise, Straight leg raise exercise. All exercises were performed for 3 sets of 15 repetitions.
• Low Intensity Exercises Program
LIE program: LIE program was similar to the HIE program. Main differences from the HIE program was repetitions of exercises. All exercises were performed by the patients for 2 sets of 8 repetitions and CPM sessions lasted each exercises session. LIE program took thirty minutes while HIE program lasted sixty minutes. Exercise intensity was monitored using the rating of perceived exertion (RPE) scale, maintaining a range between 6 and 20 RPE (16). PRE< 8 indicates low intensity, PRE>14 indicates high intensity
