Perception about running and knee joint health among the public and healthcare practitioners

Abstract Background The assessment of improvement or maintenance of joint health in healthy subjects is a great challenge. The aim of the study was the evaluation of a joint stress test to assess joint discomfort in subjects with activity-related knee joint discomfort (ArJD). Results Forty-five subjects were recruited to perform the single-leg-step-down (SLSD) test (15 subjects per group). Subjects with ArJD of the knee (age 22–62 years) were compared to healthy subjects (age 24–59 years) with no knee joint discomfort during daily life sporting activity and to subjects with mild-to-moderate osteoarthritis of the knee joint (OA, Kellgren score 2–3, age 42–64 years). The subjects performed the SLSD test with two different protocols: (I) standardization for knee joint discomfort; (II) standardization for load on the knee joint. In addition, range of motion (ROM), reach test, acute pain at rest and after a single-leg squat and knee injury, and osteoarthritis outcome score (KOOS) were assessed. In OA and ArJD subjects, knee joint discomfort could be reproducibly induced in a short time interval of less than 10 min (200 steps). In healthy subjects, no pain was recorded. A clear differentiation between study groups was observed with the SLSD test (maximal step number) as well as KOOS questionnaire, ROM, and reach test. In addition, a moderate to good intra-class correlation was shown for the investigated outcomes. Conclusions These results suggest the SLSD test is a reliable tool for the assessment of knee joint health function in ArJD and OA subjects to study the improvements in their activities. Further, this model can be used as a stress model in intervention studies to study the impact of stress on knee joint health function.

Knee joint is prominent joint, giving support to the entire body. Problems related to the knee joint such as fracture, genetic disorders, Ligament tear, and diseases like osteoarthritis etc. leads to Knee joint health problems. The adopted methodologies are X-Ray, CT, and MRI etc .This all requires periodical checkup and evaluated only when the person is having problem with the Knee joint. Continuous monitoring knee health is important and helpful for the needy. This papers aims to develop knee health monitoring device with the help of EMG signal which is acquired through vastus medialis and gastrocnemius muscles. These two are important muscles which are giving support to the knee joint. The two major skeletal muscles are investigated on the basis of their muscle reflection by giving different dynamic motions. This study includes adults, age ranging from 18-30 and aged adult from 50-60 .The EMG signals are taken from both the legs by using Muscle V3 sensor.NI-DAQ are used to acquire the signals. The result shows that there is a significant variance in the amplitude of the EMG signals with respect to the increasing age, the strength of the muscle signals which is the base for stability of the knee joint movement have been focussed in the results.

Knee acoustic emissions provide information about joint health and loading in motion. As the reproducibility of knee acoustic emissions by vibroarthrography is yet unknown, we evaluated the intrasession and interday reliability of knee joint sounds. In 19 volunteers (25.6 ± 2.0 years, 11 female), knee joint sounds were recorded by two acoustic sensors (16,000 Hz; medial tibial plateau, patella). All participants performed four sets standing up/sitting down (five repetitions each). For measuring intrasession reliability, we used a washout phase of 30 min between the first three sets, and for interday reliability we used a washout phase of one week between sets 3 and 4. The mean amplitude (dB) and median power frequency (Hz, MPF) were analyzed for each set. Intraclass correlation coefficients (ICCs (2,1)), standard errors of measurement (SEMs), and coefficients of variability (CVs) were calculated. The intrasession ICCs ranged from 0.85 to 0.95 (tibia) and from 0.73 to 0.87 (patella). The corresponding SEMs for the amplitude were ≤1.44 dB (tibia) and ≤2.38 dB (patella); for the MPF, SEMs were ≤13.78 Hz (tibia) and ≤14.47 Hz (patella). The intrasession CVs were ≤0.06 (tibia) and ≤0.07 (patella) (p < 0.05). The interday ICCs ranged from 0.24 to 0.33 (tibia) and from 0 to 0.82 (patella) for both the MPF and amplitude. The interday SEMs were ≤4.39 dB (tibia) and ≤6.85 dB (patella) for the amplitude and ≤35.39 Hz (tibia) and ≤15.64 Hz (patella) for the MPF. The CVs were ≤0.14 (tibia) and ≤0.08 (patella). Knee joint sounds were highly repeatable within a single session but yielded inconsistent results for the interday reliability.

Abstract Background Osteoarthritis (OA) of the knee is the most common type of arthritis, increasing with advancing age and external factors such as obesity. Joint health has historically relied on nutritional supplements derived from herbs and other natural products. Undenatured collagen type II demonstrated positive results with substantially lower therapeutic doses. Hence, the present study was designed to determine the efficacy and safety of Native CT-II®, an undenatured type II collagen, on the symptomatic effects in individuals having joint pain due to OA. Methods A randomized, double-blinded, placebo-controlled, parallel study was conducted on 101 slightly overweight volunteers, whose knee joint pain VAS score was ≥ 60 had been included in the study for at least three months. The participants were divided into three groups, with similar demographic and baseline characteristics. The test product containing Native CT-II®, positive control containing G+C, and the placebo were taken six tablets per day for 84 consecutive days (Three capsules to be taken post-breakfast and three capsules post-dinner). Improvement in overall joint health in each participant from baseline to end of the study was measured by WOMAC, self-administered questionnaire in Native CT-II® as compared to G+C and placebo group. Results This study demonstrated that Native CT-II® had an effective impact on the symptomatic effects of knee impairment associated with OA and in the quality of life of the participants. After 84 days, participants receiving Native CT-II® and G+C had significant improvement in overall joint health as compared to participants receiving placebo. Conclusion Native CT-II® was shown to be effective in relieving symptoms and improving quality of life for patients with knee joint pain associated with OA. Trial registration: The trial was registered with the clinical trial registry of the U.S. National Library of Medicine under National Institutes of Health (NIH) (https://clinicaltrials.gov/) with the National Clinical Trial (NCT) No: NCT04470336, Date of first registration: 14/07/2020.
