Hemp Seed Oil in Association with ß-Caryophyllene, Myrcene and Ginger Extract as a Nutraceutical Integration in Knee Osteoarthritis: A Double-Blind Prospective Case-Control Study.

Background and Objectives: Nutraceuticals are gaining more and more importance as a knee osteoarthritis (KOA) complementary treatment. Among nutraceuticals, hemp seed oil and terpenes are proving to be very useful as therapeutic support for many chronic diseases, but there are still few studies regarding their effectiveness for treating KOA, both in combination and separately. The aim of this study is thus to compare the effect of two dietary supplements, both containing hemp seed oil, but of which only one also contains terpenes, in relieving pain and improving joint function in patients suffering from KOA. Materials and Methods: Thirty-eight patients were recruited and divided into two groups. The control group underwent a 45 day treatment with a hemp seed oil-based dietary supplement, while the treatment group assumed a hemp seed oil and terpenes dietary supplement for the same period. Patients were evaluated at the enrollment (T0) and at the end of treatment (T1). Outcome measures were: Numeric Rating Scale (NRS), Oswestry Disability Index (ODI), Short-Form-12 (SF-12), Knee Injury Osteoarthritis Outcome Score (KOOS), and Oxford Knee Score (OKS). Results: All outcome measures improved at T1 in both groups, but NRS, KOOS and OKS had a greater significant improvement in the treatment group only. Conclusions: Hemp seed oil and terpenes resulted a more effective integrative treatment option in KOA, improving joint pain and function and representing a good complementary option for patients suffering from osteoarthritis.

Collagen Peptides, in Association with Vitamin C, Sodium Hyaluronate, Manganese and Copper, as Part of the Rehabilitation Project in the Treatment of Chronic Low Back Pain.

BACKGROUND AND OBJECTIVE: Low back pain (LBP) is a frequent symptom. Among the causes that can determine it, lumbar osteoarthritis plays an important role. Therapeutic exercise, according to McKenzie method, has been shown to be effective in the treatment of LBP. Oral supplementation with collagen peptides represents a new therapeutic possibility in osteoarthritis. The aim of this study is to evaluate the combined efficacy of therapeutic exercise and oral administered viscosupplements in the treatment of osteoarthritis-related chronic LBP. METHODS: Sixty patients were recruited and randomly divided into two groups (Group A and B). Group A performed only kinesitherapy, Group B carried out the same kinesitherapy combined with the daily administration of food supplements such as Fortigel®, Vitamin C, sodium hyaluronate, manganese and copper, during the whole treatment period. Patients were evaluated at the time of recruitment (T0), at the end of the treatment (T1 - 3 weeks after T0) and 6 weeks after T1 (T2). The outcome measures used were: Visual Analogue Scale (VAS), Oswestry Disability Index (ODI), and Short Form-12 (SF-12). RESULTS: All the outcomes improved significantly at T1 in both groups, but more markedly in group B. Furthermore, in group A at T2, there was a statistically significant worsening in the scores of VAS, ODI and physical component of the SF-12, while in group B, this variation has not been detected. CONCLUSION: The combination of rehabilitation based on McKenzie back exercises and oral viscosupplementation with Fortigel®, Vitamin C, sodium hyaluronate, manganese and copper represents a valid option in patients with chronic LBP, as it ensures pain relief and improvement in the quality of life and in lumbar spine functionality. These therapeutic benefits are more evident and long-lasting compared to those obtained with rehabilitation alone.
