The Addition of Contract Relax Stretching Method is Better in Increasing The Range of Motion of Knee Osteoarthritis

Knee osteoarthritis is a degenerative and chronic joint diseases due to bone and cartilage damage that can decrease the range of motion (ROM) and limit daily activities. To accelerate ROM improvement of the knee joint, authors added contract relax stretching (CRS) on the standard roll-glide (RG) and transverse friction (TF) methods. The purpose of this study to prove the addition of CRS intervention on the RG and TF mobilization further increase the knee ROM. This research was an experimental cohort study with pre-test and post-test control group design at Pelabuhan I Hospital, Medan. The research subjects were 22 people who were divided into two groups, namely the treatment group and the control group. The treatment group was given additional intervention of CRS and a control group given standard intervention. ROM improvemenet in the treatment group with a mean degree of 89.550 6.1050 before the intervention and after the intervention was 144.550 4.7190 with p = 0.001 and the control group with an average 90.910 5.3940 before the intervention, and after the intervention was 138.180 6.0300 with p = 0.001. Analysis between the treatment and control group after the intervention using independent t-test, p value = 0.012 (pless than0.05). It was concluded that the addition of CRS intervention on the standard method, further increase the ROM in patients with knee osteoarthritis.
