Cross-cultural Adaptation and Validation of the CISS and the PWES Questionnaire in Patients With Hand Pathologies.

The primary objective of the study is to do translation, cross-cultural adaptation and validation of the CISS and PWES questionnaire in French. No available translation exist in French. In the first part of the study, the investigators will use clinical guidelines for translation and cross-cultural adaptation of questionnaire (Beaton and al).The content validity will be evaluated also in this first step. In the second part of the study the French version of CISS and PWES (F-CISS and F-PWES) will be validated. Different psychometric properties (internal consistency, test retest reliability, construct validity, floor and ceiling effects) will be study. The investigators use the recommendation of COSMIN (COnsensus- based Standards for the selection of health Measurement INstruments) group.

3D Hand Orthosis Trial

In people with chronic hand conditions, hand orthoses are frequently prescribed to improve performance in activities of daily living (ADL). Conventional hand orthoses are custom-made on a plaster cast of the hand, a process that is time-consuming and labor-intensive. It has been demonstrated that the production time of manufacturing hand orthoses can be reduced by using 3-dimensional scanning and printing (i.e. 3D-printed hand orthosis), offering a promising cost-effective alternative to conventional hand orthoses. The current study builds on a previously conducted feasibility study, which demonstrated comparable effects of 3D-printed and conventional hand orthoses on ADL performance, hand function, and quality of life in people with chronic hand conditions. User satisfaction and production time favored the 3D-printed orthoses. However, to date only small and self-controlled studies have investigated the effects of 3D-printed versus conventional hand orthoses for permanent use on ADL performance and orthosis satisfaction in chronic hand conditions. Evidence from randomized controlled trials and data on the cost-effectiveness are lacking. The aims of this study are: 1. To determine whether treatment with 3D-printed hand orthoses is non-inferior compared to treatment with conventional hand orthoses in terms of ADL performance, hand function, pain, quality of life and functional status in individuals with chronic hand conditions. 2. To assess whether treatment with 3D-printed hand orthoses results in greater patient satisfaction compared to treatment with conventional hand orthoses. 3. To assess the cost-effectiveness of treatment with 3D-printed hand orthoses compared to treatment with conventional hand orthoses.

Wide-Awake Local Anesthesia No-Tourniquet (WALANT) Procedures

The goal of this clinical trial is to learn whether a standardized preoperative educational video improves expectation management and the patient experience in adults undergoing Wide-Awake Local Anesthesia No Tourniquet (WALANT) hand surgery. The main questions it aims to answer are: 1. Does watching a preoperative educational video help patients better understand what to expect from their WALANT surgical experience? 2. Does watching the video impact anxiety scores, pain scores, overall satisfaction, and patient-reported functional outcomes? Researchers will compare patients who receive traditional preoperative counseling plus the educational video with patients who receive traditional preoperative counseling alone to determine whether the video improves the patient experience. Participants will: * Complete questionnaires about their expectations, anxiety, pain, hand function, and satisfaction before, during, and after their WALANT procedure. * If assigned to the video group, watch a standardized educational video explaining what to expect before, during, and after WALANT surgery. * Complete their final study questionnaires at their 2-week postoperative follow-up visit.

Video-Based Physiotherapy Education and Social Participation in Adults With Hand Injuries

The goal of this clinical trial is to determine the factors affecting social participation in adult patients with hand injuries and to evaluate the effectiveness of a video-based physiotherapy awareness education in this population. The main questions it aims to answer are: Does a short, video-based physiotherapy education increase the knowledge and awareness levels of patients with hand injuries? What are the primary factors (body functions and activity limitations) that restrict the social participation of these patients? Participants will: Complete baseline assessments including a sociodemographic form, the Quick-DASH questionnaire, and custom participation and awareness forms. Receive a 10-15 minute video-supported education session from physiotherapists covering home strategies, exercises, and assistive devices. Complete the knowledge and awareness test again immediately after the education session to measure acute changes.

Perineural vs Intravenous Dexamethasone as an Adjuvant to Brachial Plexus Block in Pediatric Hand Surgery

This clinical trial will evaluate the neurological safety and analgesic effectiveness of dexamethasone administered perineurally or intravenously as an adjuvant to brachial plexus block in children undergoing hand or forearm surgery. Dexamethasone is commonly used to prolong the duration of regional anesthesia, but there is limited evidence on long-term neurological safety, particularly in pediatric patients. All participants will receive a single-shot brachial plexus block using ropivacaine under ultrasound guidance. Patients will be randomized into one of three treatment groups: perineural dexamethasone, intravenous dexamethasone, or placebo. The primary objective is to determine whether perineural dexamethasone causes any clinically significant nerve injury compared with intravenous administration or placebo. Neurological function will be assessed clinically and via serum neurofilament light chain (NfL) levels over a 12-month follow-up period. This study may provide evidence regarding the long-term safety profile of perineural dexamethasone in children and help establish evidence-based dosing and administration guidelines.

Effect of Systematic Dexamethasone on the Duration of Supraclavicular Brachial Plexus Block for Anesthesia After Pediatric Hand/Wrist Surgery

Early Functional Response as a Predictor of Clinical Outcomes in Hand Rehabilitation: A Prospective Feasibility Study Using a Digital Monitoring System

This study investigates whether early changes observed during the first weeks of hand and upper extremity rehabilitation can predict patient outcomes months later. In rehabilitation practice, clinicians make numerous decisions each session regarding exercise type, frequency, duration, and treatment approach. Most of these decisions are currently made without systematic longitudinal data. This study addresses three fundamental questions using data collected during routine clinical care: (1) Can the rate of improvement in the first weeks of treatment predict functional status months later, across both session-based and milestone-based time points? (2) Are there meaningfully different recovery profiles among hand rehabilitation patients? (3) Is there measurable variation in clinical decision-making among patients with similar profiles, and does this variation relate to outcomes? A digital patient monitoring platform developed by the principal investigator, a physiotherapist and academic researcher specializing in hand rehabilitation serves as the data collection infrastructure. The platform records standard clinical assessment measures in a structured format and has been in active clinical use at Hacettepe University prior to this study. For research purposes, the system has been expanded to include structured capture of patient-reported outcomes, patient global impression of change, treatment protocol coding, home exercise adherence, and automated calculation of early response metrics. This is a 12-month prospective observational cohort study enrolling a minimum of 60 patients. Data are stored securely on the university's institutional network. Patients are anonymized using identification codes. The study is subject to Hacettepe University Ethics Committee approval and participant informed consent. Findings are expected to generate evidence supporting data-driven clinical decision-making in rehabilitation and to provide a feasibility foundation for a larger multi-center study.

The ACTS Trial: N-acetylcysteine (NAC) and Night-splinting as a Non-operative Treatment for Carpal Tunnel Syndrome

Carpal tunnel syndrome (CTS) is the most common nerve compression syndrome worldwide, causing significant chronic pain, functional impairment, and lowered quality of life for individuals of various backgrounds. CTS is caused by chronic compression of the median nerve in the carpal tunnel of the wrist, causing numbness and pain in the palm, thumb, index, and middle fingers and eventual weakness of the hand. Many different treatments for CTS have been proposed and studied, including but not limited to non-operative treatments such as wrist splinting, steroid injections, and lifestyle modifications as well as operative treatments, such as surgical carpal tunnel release (CTR). To date, very few oral medications have been shown to be effective as conservative treatments for CTS. In this study the investigators will examine whether there is any benefit to using oral N-acetylcysteine (NAC) as an adjunctive treatment for mild to moderate CTS in addition to a standard 8-week trial of night splinting. NAC has been used in humans for various purposes, is extremely safe and has very few side effects, and has been shown to have anti-inflammation properties which may help treat CTS. The investigators will study this by performing a randomized controlled trial, comparing patients receiving oral NAC and standard night splinting to patients receiving an identical placebo and standard night splinting. Both patient groups will be assessed using a questionnaire to assess for severity of their CTS symptoms both before and after the 8-week treatment. The primary objective will be to determine whether supplementation with oral NAC in addition to night splinting has any significant impact on patient-reported symptoms and functional impairment when compared to night splinting alone. The investigators will also measure secondary outcomes including whether patients decide to have surgery for their CTS after treatment and/or continued use of other treatments. This study has the potential to have a significant positive impact on patients by identifying a safe, inexpensive, accessible, and well tolerated conservative treatment for mild to moderate carpal tunnel syndrome, and potentially preventing the need for additional, more invasive treatments such as surgery.
