Abstract

Objective: Compare the time difference between sitting to standing movements with knee flexion angle 90⁰ and knee flexion angle 120⁰  between patients with knee osteoarthritis and healthy people. Subjects and methods: Patients with KOA and healthy people in the Ho Chi Minh city community, Department of Physical Therapy, An Binh hospital. Results: A total 20 subject, 2 men and 18 women, participated in the study. Average age 62,85 ± 6,37. The time in the preparation phase (CB) when moving sitting to standing at a knee flexion angle of 90⁰ in the KOA group is (0,94 ± 0,34 seconds) longer than the healthy group is (0,61 ± 0,06 seconds) (t= 3,03, p = 0,013). When performing  sit-to-stand with a 120⁰ knee flexion, the time in the CB phase of the KOA group is (0,95 ± 0,21 seconds) longer than the healthy group 0,60 ± 0,09 seconds) (t = 4,86, p<0,001). In the rising phase (NL), when moving from sitting to standing with a knee flexion angle of 90⁰, the KOA group was (1,12 [0,67; 1,66] seconds) longer than the healthy group (0,74 [0,71; 0,96] seconds) (Z = -2,80, p= 0,005). Moving from sitting to standing with a knee flexion angle of 120⁰, the time spent in the NL phase in the KOA group is (0,85 ± 0,24 seconds) longer than the healthy group (0,61 ± 0,12 seconds) (t= 2,81, p=0,012). Conclusion: Patients with KOA need more time to sit to stand than healthy people in both the CB and NL phase at two knee flexion angles of 90⁰ and 120⁰.
