A randomized controlled trial of a combined self-management and exercise intervention for elderly people with osteoarthritis of the knee: the PLE²NO program

Abstract

This study supports the importance of a combined self-management and exercise intervention to improve functional lower limb strength and aerobic capacity in a Portuguese sample. Additionally, pain and other symptoms have improved clinically.

What interventions can improve quality of life or psychosocial factors of individuals with knee osteoarthritis? A systematic review with meta-analysis of primary outcomes from randomised controlled trials

“…However, one data set was duplicated and published in two different manuscripts38 39; therefore, the later one was excluded 38. From the 23 studies included in this SR, most studies (n=19) evaluated QoL,39–57 one study evaluated self-efficacy,56 one study evaluated helplessness,58 one evaluated pain catastrophising,56 two evaluated coping strategies,56 59 one evaluated depression and psychological distress,60 and one evaluated cognitive symptom management (CSM)61 in individuals with knee OA. The study of Broderick et al 56 considered more than one outcome as primary.…”

“…There was very limited evidence from one study61 with small effect in favour of a combined self-management programme and exercise intervention to improve CSM of individuals with knee OA compared with self-management programme only (SMD=0.52, CI 0.03 to 1.01) (figure 6). …”

The Role of Physical Activity as Conservative Treatment for Hip and Knee Osteoarthritis in Older People: A Systematic Review and Meta-Analysis

“…Also, when comparing Tai Chi or Yoga with aquatic and aerobic exercise [30,35], there were uncertain results on symptom improvement, pain relief, and perceived function. In five studies [44,45,[47][48][49], active exercise represented the only intervention group, and in all of those participants in the study group showed significant improvement in the checked outcomes, such as WOMAC, KOOS, VAS, 6-MWT, and get-up-and-go test. On the other hand, only one study [43] reported no differences between the rehabilitation group and the control group in any outcome measure.…”

“…Of the RCTs, six studies checked sports activity n = 4 Tai Chi [30][31][32][33], n = 2 yoga [34,35]. The remaining RCTs were focused on water-based and land-based exercises: there were three studies with three arms (hydrotherapy, land-based exercise and control group) [36][37][38], four studies that compared only hydrotherapy with controls [39][40][41][42], and seven studies that only evaluated land-based exercises [43][44][45][46][47][48][49].…”

“…Therefore, they showed the "noninferiority" of exercises compared with NSAIDs as a therapy for knee OA. Marconcin et al [47] allocated 67 patients aged 60 years or older with knee OA to a self-management and exercise intervention or an educational intervention. In the self-management and exercise group, significant improvements in all KOOS dimensions (larger than 10 points) and in the 6 MWT (p = 0.035) were found.…”
