Review Meta Analysis
The effect of experimentally induced pain in the cervical, shoulder or orofacial regions on cervical neuromuscular and kinematic features: a systematic review and meta-analysis.
In this systematic review, we synthesize the literature investigating the effect of experimentally induced pain in the cervical, shoulder, or orofacial regions on cervical neuromuscular and kinematic features. Databases were searched up to November 1, 2023. A total of 29 studies using hypertonic saline injection (n = 27) or glutamate injection (n = 2) as experimental pain models were included. ⋯ PERSPECTIVE: This systematic review and meta-analysis revealed a reduced or unchanged muscle activation during experimental pain in the cervical, shoulder, or orofacial regions, depending on the task and location of nociceptive stimulation. There was inconsistent evidence on cervical kinematics. These findings enhance our understanding of neuromuscular adaptations to acute experimental pain.

Review Meta Analysis
Acupuncture Provides Short-term Functional Improvements and Pain Relief for Patients after Knee Replacement Surgery: A Systematic Review and Meta-analysis.
The impact of acupuncture on knee function and pain intensity following knee replacement remains controversial. Therefore, we categorized the postsurgery recovery period into 3 phases: short-term (≤2 weeks), intermediate-term (2 weeks-3 months), and long-term (>3 months), and then assessed the effectiveness of acupuncture in improving function and alleviating pain at different stages following knee replacement. This meta-analysis included randomized controlled trials that compared acupuncture intervention with either no treatment or a sham group after knee replacement. ⋯ PERSPECTIVE: This article demonstrates that acupuncture has short-term effects (≤2 weeks) on improving active range of motion and reducing pain during rest and during movement following knee replacement surgery. The findings support the early application of acupuncture in hospital settings after knee replacement. REGISTRATION ID: The study was registered on PROSPERO (CRD42024503479).
