Hand Osteoarthritis

This clinical trial aims to find out if using 1 gram of Multiprofen-CC cream on the hands three times a day for 4 weeks can help reduce pain in adults with hand osteoarthritis, compared to a placebo (a cream with no active medicine). The research team will also look at how Multiprofen-CC affects hand function, opioid use, and how patients feel about their overall improvement. In addition, the research team will keep track of any side effects. Participants will: * Use both Multiprofen-CC and a placebo (a cream with no active medicine) during the study, in a random order. * Be asked to apply 1 gram of cream to their hands three times a day for 2 weeks, following the manufacturer's instructions. * Attend a visit before starting the study, after 2 weeks, and after 6 weeks. * Report any symptoms they experience during the study.

The goal of this clinical trial is to determine the efficacy and safety of intramuscular methylprednisolone in patients with hand osteoarthritis. The main question it aims to answer is what the difference is in hand pain 4 weeks after the first injection with methylplrednisolone. This main goal will be assessed in the first 16 weeks, the RCT phase. Researchers will compare 120mg methylprednisolone with 40mg methylprednisolone and placebo to see if there is a difference in hand pain after 4 weeks. Participants will be asked to visit the hospital for: * injection of the study material * ultrasound assessment * physical examination like joint assessments and grip strenght * examination of blood * x-ray of the hand In phase 2, from week 16 to 48, an open label phase focusing on treatment strategy and safety. In this phase all participants may receive intramuscular methylprednisolone on demand at the dosage of 120mg only if they fulfil the following conditions: hand pain \> 30mm on a VAS (0-100mm) and a minimum of 16 weeks interval between two consecutive injections. Therefore, a maximum of two injections could be received during this period. Irrespective of that, all participants will be followed-up until week 48 when the end-of-study visit will take place.

The late-stage forms of degenerative osteoarthritis (OA) are very debilitating and less affordable to therapy. The main objective is to identify early onset symptoms of hand OA patients through imaging techniques (such as ultrasound and MRI). Our primary endpoint is to specify patients with high risk of radiological profression (X-ray).

The investigators plan to conduct this multicentered, sham-controlled randomized clinical trial to evaluate the efficacy and safety of acupuncture for clinical symptomatic improvement of hand OA.

The goal of this study is to to examine the feasibility of a full-scale trial on Helping Hand, a new Joint Protection Program for Hand Osteoarthritis and to examine the acceptability of the new Joint Protection Program. This study will not assess the effectiveness of the program, as it is not designed or powered to do so. Instead, the information gathered will be used to refine the trial design and ensure the future full-scale trial that will assess the effectiveness of the program is robust and successful. The acceptability of the new Joint Protection Program will be assessed through a survey that will be administered to the intervention group at the end of the trial, which will be based on a standardized acceptability framework Participants will: Gain access to an online Joint Protection Program or continue to receive usual care for 12 weeks Visit the clinic or complete online assessments once every 4 weeks Keep a diary of their symptoms and the number of times they used other interventions to manage their symptoms (i.e. painkillers)

To compare metformin (2 g daily), or maximum tolerated dose, for 16 weeks with placebo as a treatment of hand osteoarthritis symptoms.

To investigate the research design (pilot-RCT) and feasibility of the HANDY program for people with hand osteoarthritis (version 2.0). In collaboration with two municipalities (Lyngby-Taarbæk and Ballerup), the research design is tested in a pilot-RCT before planning a full-scale RCT study. The entire HANDY program is described in a manual, which has been adjusted to version 2.0 based on a previous feasibility study. The focus of the study will be on procedures related to recruitment and retention, the study's acceptance in practice, and the appropriateness of assessment tools in connection with the occupational therapy group intervention. The feasibility and acceptance of the HANDY program version 2.0 are also examined in this study.

There are a limited number of studies in the literature on the effectiveness of balneotherapy in hand osteoarthritis. The aim of this study was to evaluate the effects of balneotherapy on pain, manual skills, functionality and quality of life in patients with hand osteoarthritis who have undergone balneotherapy.

The goal of this trial is to evaluate the efficacy of an integrated self-management programme in improving clinical outcomes in patients with hand osteoarthritis (OA). This is an open-labelled, randomized controlled trial with an objective to determine the efficacy of an integrated self-management programme versus routine clinical care for participants with symptomatic hand OA. Participants will be randomized into early intervention group and routine clinical care groups in a 1:1 ratio. Patients who randomized into early intervention group will receive 8 week integrated self-management programme delivered by occupational therapists and rheumatology nurse on hand OA management. Patients who randomized into routine clinical care group will receive usual clinical care for OA for 26 weeks and then receive an identical 8 weeks integrated self-management programme. The primary outcome is the improvement in pain at 26 weeks between the two groups.
