![]() Participants were asked to stand at the 2-m tape line ahead of the 10-m line and then walk at a comfortable pace to the 12-m tape line beyond the 10-m line. The first and last 2 m of the course were used for acceleration and deceleration and were not timed. Tape, at 2 and 12 m, indicated the start and end of the 10-m walking distance. The 10MWT measured the time required for the participant to walk 10 m on a course that was a total distance of 14 m. The 10MWT is a measure of one's walking ability with an intra-rater and inter-rater reliability correlation coefficient of r = 0.95 to 0.96. Walking ability was assessed using a 10-m walking test (10MWT). The minimal clinically important difference (MCID) of VAS was reported as 1.2 regardless of the degree of pain. VAS is a scale for assessing pain, ranging from 1 to 10 points (0 points with no pain at all, 10 points with maximum pain). Knee pain during the resting state was assessed in the standing position before walking, and pain during gait was assessed immediately after walking. This study utilized the visual analogue scale (VAS) to assess knee pain during resting and walking phases in 2 conditions (KT and non-KT). Each testing session consisted the following actions: application (or not) of KT from below the patella to the quadriceps and proximal tibia, assessment of walking ability, dynamic balance ability, and pain severity. KT is applied from above the patella to the proximal tibia with an approximate 10% to 15% stretch in both downward directions (Fig. KT is applied from below the patella to the distal femur with an approximate 10% to 15% stretch in both upward directions (Fig. KT is applied from below the patella to the medial area of the quadriceps muscle with an approximate 10% to 15% stretch (Fig. KT is applied from below the patella to the lateral area of the quadriceps muscle with an approximate 10% to 15% stretch (Fig. The application method of KT is as follows. All participants were assessed in 2 conditions (KT and non-KT) and the order was randomized using a coin toss. KT (BB Tape, WETAPE Inc., Pyeongtaek, Korea) was applied by one experienced physical therapist on both knees. This study was conducted using a one-group, pre and post design. Ethical approval was obtained from the Seoul Medical Center Institutional Review Board before conducting the experiment (SEOUL 4-001). We explained the objective and requirements of our study to all the participants and they voluntarily signed informed consent forms. The exclusion criteria were as follows: knee swelling, underlying skin disorders, rheumatoid arthritis, previous knee joint surgery, and a planned surgical procedure on the knee joint within the next 6 months. The inclusion criteria were as follows: 60 years old or older, diagnosed with knee OA by radiography, the surgeon then determined the grade of knee OA (1–3) according to the Kellgren and Lawrence (1957) scale (Table (Table1), 1), independent walking is possible, can carry out activities of daily life independently, and visual analog scale (VAS) score of knee pain >5. A total of 10 volunteer subjects with knee OA were recruited for the study. This study was conducted at an elderly welfare facility in South Korea. ![]() We hypothesized that KT would aid in knee pain reduction and enhance gait and balance ability than non-KT condition. Therefore, the purpose of this study was to investigate the effect of knee KT on the gait of the older adults with OA and to establish the clinical basis of this effect. ![]() In other words, since the effect of KT depends on the application type, it is important to introduce various application methods to prove the effect. However, KT can be applied using various designs depending on the researcher, and the effect of each is different. ![]() Several studies have recently reported the effectiveness of KT in terms of the reduction in the patellofemoral pain and improvement of posture control during functional activities. Because inflammatory soft tissue can become worse when stretched, application of patella taping can provide stability to the knee by reducing the load on the infra-patellar fat pad or pesanserinus. KT alleviates knee pain by improving patellofemoral alignment and relieving the pressure and stress on soft tissues. There have been several methods of taping that have been applied. ![]() One of the treatments, kinesiology taping (KT), is carried out by applying an adhesive strapping tape to the patella or surrounding soft tissue structures. Therefore, appropriate treatment and exercise is important for the older adults with knee OA. Knee osteoarthritis (OA) has a high incidence, and the symptoms include joint pain and stiffness, reduced range of motion, and pain that is exacerbated by activities such as climbing stairs, getting up from a chair, and walking for a long time. ![]()
