简要总结
This randomized controlled trial evaluates the effectiveness of three distraction techniques-virtual reality (VR) headset, squishy (squeeze toy), and poetry reading-on postoperative pain control in adults undergoing total knee arthroplasty. Participants are randomized into four parallel groups (three intervention arms and one usual care control). Pain intensity is assessed using the Visual Analog Scale (VAS), with primary assessment at 24 hours after surgery.
详细描述
Total knee arthroplasty is a common orthopedic procedure that can be associated with significant postoperative pain. In addition to standard pharmacological analgesia, non-pharmacological approaches such as distraction techniques may help reduce perceived pain by redirecting attention away from nociceptive stimuli. This single-center, parallel-group randomized controlled trial will be conducted in the Orthopedics and Traumatology Clinic of Osmaniye State Hospital in Türkiye. Eligible adults (≥18 years) undergoing total knee arthroplasty will be randomized using a stratified block randomization approach based on baseline pain severity (VAS 0-3, 4-6, 7-10) to ensure balanced allocation across groups. The intervention arms include (1) VR headset distraction, (2) use of a squishy (squeeze toy) as a tactile distraction method, and (3) poetry reading as a cognitive distraction method. The control group receives usual postoperative care without a structured distraction intervention. All groups follow the same postoperative analgesia protocol. The primary outcome is postoperative pain intensity measured by VAS at 24 hours after surgery.

研究组 & 干预措施
Virtual Reality (VR) Headset
Participants will receive routine postoperative care and standard analgesia according to the hospital protocol. In addition, they will receive a structured distraction intervention using a virtual reality (VR) headset during the postoperative pain period while hospitalized (e.g., within the first 24 hours after surgery). The VR content is delivered under supervision at the bedside as a non-pharmacological distraction method.
干预措施: VR Distraction (Behavioral)
Squishy (Squeeze Toy)
Participants will receive routine postoperative care and standard analgesia according to the hospital protocol. In addition, they will use a squishy (squeeze toy) as a tactile distraction method during the postoperative pain period while hospitalized (e.g., within the first 24 hours after surgery). Participants are instructed to use the squeeze toy during episodes of pain/discomfort as a non-pharmacological distraction technique.
干预措施: Tactile Distraction With Squishy (Behavioral)
Poetry Reading
Participants will receive routine postoperative care and standard analgesia according to the hospital protocol. In addition, they will perform poetry reading as a cognitive distraction method during the postoperative pain period while hospitalized (e.g., within the first 24 hours after surgery). Poetry reading is provided as a structured non-pharmacological distraction intervention at the bedside.
干预措施: Poetry Reading Distraction (Behavioral)
Usual Care Control
articipants will receive routine postoperative care and standard analgesia according to the hospital protocol. No structured distraction intervention (VR, squishy, or poetry reading) will be provided.
