Brief summary

This research evaluated the effects of UCII, glucosamine and curcumin supplementation on knee pain and inflammation.

Detailed description

Arthritis is an inflammation of one or more joints, characterized by pain, stiffness (especially in the early morning or after exercise), swelling, deformation, and/or reduced mobility. There are many different forms of arthritis. Osteoarthritis, also known as degenerative arthritis, is caused by abnormal damage to the cartilage at the ends of bones. In some patients, it is caused by injury or congenital abnormalities in the proteins that make up cartilage. Generally, it seems that aging, an unbalanced diet, and an inappropriate lifestyle are the causes of this disease. Once the cartilage tissue changes from smooth to rough or breaks into small pieces, the cartilage is gradually destroyed, and the normally smooth surface becomes irregular. Osteoarthritis usually occurs in joints that bear weight, such as the spine, knees, hips, and back. It is usually preceded by pain and symptoms of stiffness (often stiffness first, then pain), but swelling is not always present. In a small number of cases, osteoarthritis can cause disability. As the condition progresses, the bones can become more fragmented, increasing the likelihood of fractures. When osteoarthritis is more severe, bones can overgrow into osteophytes, known as bone spurs. These bone spurs can be detected with X-rays, usually near degenerative cartilage in the neck or waist. However, these changes typically do not alter the appearance of the affected area. There are more than 28 types of peptides that make up collagen, with the more common types I, II, and III collagen accounting for about 90% of the total. Type II collagen forms joints. When collagen from pork bones and other sources is cooked at high temperatures, the collagen structure is destroyed, becoming denatured collagen. Additional supplements can only be used as general collagen and, therefore, cannot reduce the damage and inflammation of joint cartilage. Many studies have confirmed that the use of 'non-denatured type II collagen' (UC-II) can provide flexible maintenance for key parts. To achieve higher efficiency and longer-lasting effects, it is combined with glucosamine, chondroitin, and curcumin. In addition to providing resistance to compression in articular cartilage, it can also improve inflammation and significantly reduce pain in patients with primary osteoarthritis. Therefore, this research evaluated the effects of UCII, glucosamine and curcumin supplementation on knee pain and inflammation.

MeasureTime frameDescription
Points Change of Pain Evaluation Scalebaseline, week 6, week 12Self-assess pain using a visual analog scale (VAS), which is a straight line 10 cm in length, with 0 cm on the left representing no pain and 10 cm on the right representing extreme pain. Explain to the subjects that the pain intensity increases from left to right. Ask the subjects to mark the point on the line that corresponds to their pain level, and then record the distance in centimeters from the 0 cm mark. Record the points that the subjects wrote.
Time Change of Up-and-go Testbaseline, week 6, week 12Timed up-and-go test (TUG) was a professional physical therapist marked a distance of 3 meters on the ground and placed an armless chair at one end. The subject sat on the chair with a straight back, and the time was measured from when the subject stood up and walked to the 3-meter mark at their usual speed, turned around, walked back, and sat down again. Shorter time spent indicates better knee function. Record the time that the subjects spent.
Degrees Change of Range of Motion (ROM)baseline, week 6, week 12A professional physical therapist tested the active flexion and extension of the knee joint (range of motion, ROM) as the subjects attempted to achieve maximum active flexion and extension. Record the angle that the physical therapist measured. AROM: active range of motion; PROM: passive range of motion
Points Change of Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)baseline, week 6, week 12Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), a widely used questionnaires used by health professionals to evaluate the condition of patients with osteoarthritis of the knee and hip, and the total score was 96 points (Minimum: 0 points; Maximum: 96 points). The question content was divided into three parts: Pain (20 points), Stiffness (8 points), and Physical function (68 points). The higher score meant worse knee joint function. Record the points that the subjects got.
The Concentration of Serum Inflammatory Factorsbaseline, week 6, week 12The concentration of interleukin-6 (IL-6), interleukin-1 beta (IL-1β), and tumor necrosis factor alpha (TNF-α) in serum.

The question content was divided into three parts: Pain (20 points), Stiffness (8 points), and Physical function (68 points). The higher score meant worse knee joint function. Record the points that the subjects got.

Time Change of Up-and-go Test

Timed up-and-go test (TUG) was a professional physical therapist marked a distance of 3 meters on the ground and placed an armless chair at one end. The subject sat on the chair with a straight back, and the time was measured from when the subject stood up and walked to the 3-meter mark at their usual speed, turned around, walked back, and sat down again. Shorter time spent indicates better knee function. Record the time that the subjects spent.

Comparison: This analysis examined the overall (main) effect of treatment-comparing Control and Test groups across the three time points (baseline, week 6, and week 12) Comparison groups: Control and Test group of up-and-go test on baseline, week 6, and week 12.p-value: 0.399ANOVA
Comparison: It calculated the interaction between 2 groups (Control group and Test group) X 3 time points (Baseline, week 6, week 12) of timed up-and-go test.p-value: 0.106ANOVA
