Is aquatic exercise more effective than land-based exercise for knee osteoarthritis?

Background: Knee Instability (KI) is described as a sense of knee buckling, shifting, or giving way during the weight bearing activities. High prevalence (60-80%) has been reported for KI amongst the patients with knee osteoarthritis (KOA). In this line, the present study targeted the effect of two interventions on self-reported KI and affected factors. Methods: In this single blind, randomized, and controlled trial, 36 patients with radiographic grading (Kellgren–Lawrence > II) of KOA were selected. Patients were divided into three groups namely, aquatic (n=12), Total Resistance exercises (TRX) (n=12) and control (n=12) by random. Then both 8-week TRX and aquatic exercises were carried out by experimental groups. The following measure were taken before and after interventions: Pain by visual analog scale (VAS), balance by Berg Balance Scale (BBS), quadriceps strength by dynamometer, knee flexion range of motion (ROM) by inclinometer, knee stiffness with Western Ontario and McMaster Universities Osteoarthritis (WOMAC), and self-reported KI with Felson's questionnaire. Results: The results demonstrated that KI, VAS, BBS improved over time both in TRX and aquatic groups significantly (p<0.05), but WOMAC(stiffness), knee flexion ROM, and quadriceps strength were significantly improved over time only for TRX (p<0.05). Post hoc test, also, showed that there were significant differences between interventions and control groups (p<0.05) for the VAS, KI, BBS, but for WOMAC(stiffness), a significant difference was observed only between TRX and control groups (p=0.05). Conclusions: Although TRX and aquatic interventions had a similar effect on the patients’ balance, pain and KI, TRX had more effect on WOMAC(stiffness), quadriceps strength, and knee flexion ROM than aquatic exercises.

Background Knee Instability (KI) is described as a sense of the knee buckling, shifting, or giving way during the weight bearing activities. High prevalence (65%) has been reported for KI amongst the patients with knee osteoarthritis (KOA). So, we studied the effect of two interventions on self-reported KI and affected factors.Methods In this single blind, randomized, and controlled trial, 36 patients with radiographic grading (Kellgren–Lawrence 1–4) of knee osteoarthritis were selected for participating. patients were allocated in three groups aquatic exercises (n=12), Total Resistance eXercises (TRX) exercises (n=12) and control (n=12) by random. 8-week TRX and aquatic exercises were carried out by experimental groups. Pain severity was assessed by visual analog scale (VAS), Balance was also evaluated by Berg Balance Scale (BBS), quadriceps strength by dynamometer, and knee range of motion (ROM) by inclinometer, Western Ontario and McMaster Universities Osteoarthritis (WOMAC), self-reported KI were also measured before and after interventions.Results The results of One-way ANOVA showed that there was no significant difference between aquatic exercises and TRX (P>0.05) for KI, BBS, WOMAC, and pain. But there was significant difference between the aquatic exercises and the control for KI (P=0.0001), BBS (P=0.0001), WOMAC Stiffness (P=0.0001), and pain (P=0.006). Also, there was significant difference between the TRX and the control for KI (P=0.0001), BBS (P=0.0001), and pain (P=0.003) except WOMAC Stiffness (P=0.07).Conclusions TRX and aquatic interventions had a similar effect on the patients’ KI, pain, function, and also balance variables, but TRX exercises had more effect on the knee stiffness improvement.

“…However, no significant difference in aquatic and control groups for WOMAC stiffness was reported. It seems that TRX exercises could reduce compensatory knee joint-stiffening strategy by significantly strengthening the dynamic knee stabilizer muscles They reported the same results for aquatic exercise for adults with arthritis as those of land-based exercises [42,43]. Likewise, Wyattet al (2001) conducted a study to detect differences between an aquatic exercise program and a land-based exercise program on KOA patients' pain and function.…”
