Data on the efficacy of treatment modalities in De Quervain’s tenosynovitis (DQT) is limited. Paraffin therapy is routinely used in treating hand osteoarthritis and neuropathies. However, there are not enough studies investigating paraffin effectiveness. This study evaluates the effectiveness of paraffin bath therapy on pain, functional status, muscle strength, and quality of life in patients with DQT. This prospective, single-blind, randomized, controlled study enrolled 51 DQT patients. Group 1 (n = 26) received paraffin bath + splint + exercise; Group 2 (n = 25) received splint + exercise therapy. Pain, handgrip strength, thumb palmar pinch strength, functional status, and quality of life were evaluated. Both treatment combinations improved pain, grip strength, palmar pinch strength of the thumb, functional status, and quality of life. The paraffin group provided more effective pain control than the paraffin-free group and was more effective in improving functional status, handgrip strength, and quality of life (p < 0.05). Apparently, adding paraffin therapy to the combination of the splint and therapeutic exercise positively affects the patient’s treatment outcomes. For this reason, paraffin therapy should be included in the conservative treatment combinations in DQT.

关于 De Quervain 腱鞘炎 (DQT) 治疗方式有效性的数据有限。石蜡疗法通常用于治疗手部骨关节炎和神经病。然而，没有足够的研究调查石蜡的有效性。本研究评估石蜡浴疗法对 DQT 患者疼痛、功能状态、肌肉力量和生活质量的有效性。这项前瞻性、单盲、随机、对照研究招募了 51 名 DQT 患者。第 1 组 ( n = 26) 接受石蜡浴 + 夹板 + 运动；第 2 组 ( n= 25）接受夹板+运动疗法。评估疼痛、握力、拇指捏掌强度、功能状态和生活质量。两种治疗组合都改善了疼痛、握力、拇指的手掌捏力、功能状态和生活质量。石蜡组比无石蜡组更有效地控制疼痛，在改善功能状态、握力和生活质量方面更有效（p < 0.05）。显然，在夹板和治疗性运动的组合中加入石蜡疗法会对患者的治疗结果产生积极影响。因此，石蜡治疗应包括在 DQT 的保守治疗组合中。
