Dıracogluet al (2005) Two
group
trial
66/60 Range 35-65 (mean not reported) ACR 8 weeks
(3x/wk)
KBA + RT vs RT Proprioceptive acuity; WOMAC; SF-36; 10 stairs climbing; 10-m walk; isokinetic muscle strength Both groups improved all measures; WOMAC function better in KBA; SF-36: physical function, role limitations (physical) and vitality (energy or fatigue) higher in KBA; KBA > RT on stair climb, walk; no between group difference on proprioceptive acuity
Fitzgerald et al(2011) RCT 183/ITT
analysis
64.6 (8.4);
63.3 (8.9)
ACR, KL 2+ 12 supervised sessions over 6-8 wks, then HEP through 6 months RT vs RT + KBA (2x/wk + walking 30 min 3x/wk) WOMAC; subjective knee stability; knee pain; global rating of change in symptoms; get up & go walk Both improved self-reported function and global rating of change at 2-, 6-, and 12-month, no differences between groups. No change knee pain or up & go. No additive effect of agility and perturbation training with RT.
Sekir & Gur (2005) RCT 22/22 59 (8.9);
62 (8.1)
ACR, radiographs; bilateral knee OA 6 weeks Proprioceptive exercise vs Control Pain; get up & go walk; stair ascent/descent; joint position sense; balance; isometric & isokinetic strength Exercise improved postural control, functional capacity, and knee pain in patients with bilateral knee OA.

trail
48/42 62 (6)
70 (6)
ACR 4 weeks
(5x/wk)
Balance training (stepping forward/ back/sideways,mini-squats) vs Isometric quads RT, multi position Pain; knee symptoms; isokinetic knee strength; 15m walk; 15m up & go walk; stair ascent, descent Both equally effective in improving pain and most symptoms, strength, walks, stair climb (RT > balance on stair descent)

trial

(11.4)
Physician Dx knee OA 8 weeks
(3x/wk)
RT vs KBA WOMAC; community physical activity; exercise self-efficacy; knee stability self report; 15m up & go walk; stair ascent/descent Both improved WOMAC Physical Function (KBA 59%, RT 40%), and subjective knee stability. Community physical activity level improved only in KBA; There were no between-group differences. Both appear to improve function and knee stability.
