Background Rheumatoid arthritis (RA) is a chronic, systemic inflammatory disease of unknown etiology that produces a progressive degeneration of the musculoskeletal system .
The management of RA rests on drug treatment and non-pharmacological measures such as exercise, occupational and psychological therapeutic approaches . Exercise in RA is believed to improve joint mobility, muscle strength, and physical function . Therapeutic exercise is important for pain control. Stretching is often included in physical therapy interventions for management knee pain. One of stretching techniques is post-isometric relaxation (PIR) .
Objectives In this study we wanted to check effectiveness of reducing pain using kinesiotherapy and post-isometric relaxation in RA patient with knee pain.
Methods The patient were examined at entry to the hospital. Patient who had RA were eligible for the study if they fulfilled inclusion and exclusion criteria. They were separated into 2 groups: I (kinesiotherapy) [n=19] and II post-isometric relaxation (PIR) [n=19]. Kinesiotherapy was performed once a day for 30 minutes. Group II had kinesiotherapy as I group and PIR on 3 groups of muscle: knee flexors, knee extensors and plantar flexors of the foot. Therapy lasted for 10 days.
The knee pain of the patients was assessed by visual analogue scale (VAS) pain score (0-100 mm, with higher scores indicating more pain).
Results See Table 1.
Statistically significant differences in VAS were noted after treatment in both groups: Group I - it decreased from 59.9 (10.85) to 45.9 (19.19), p=0.0016; Group II - it decreased from 67.5 (14.9) to 32.7 (15.8), p=0.0000. Therapy in Group II was statistically significant better than Group I, p=0.0147.
Conclusions The study showed positive, statistically significant effects of kinesiotherapy alone and kinesiotherapy with post-isometric relaxation on the pain in these research. However, due to the relatively small groups it is difficult to draw firm conclusions. Because of positive effects of treatment on knee pain in patient with RA, research should be continued in this area.
