Summary
This study investigates intraoral acupuncture for post-stroke sialorrhea (PSS), comparing it to sham acupuncture. Findings will inform PSS treatment and clarify salivation issues after stroke.
Area of Science:
- Neurology
- Rehabilitation Medicine
- Integrative Medicine
Background:
- Post-stroke sialorrhea (PSS) significantly impacts quality of life, affecting self-image, social interaction, and potentially leading to depression.
- Current evidence linking excessive salivation to PSS is limited, and large-scale trials on acupuncture's efficacy are lacking.
Purpose of the Study:
- To compare the effectiveness of intraoral acupuncture versus sham acupuncture in managing PSS.
- To explore the relationship between salivation, drooling severity, and swallowing function in stroke patients.
Main Methods:
- A prospective, single-center, randomized, sham-controlled trial involving 106 PSS patients.
- Participants will receive 4 weeks of either intraoral or sham acupuncture.
- A control group of 53 stroke patients without PSS will also be monitored.
Main Results:
- The primary outcome is the change in 3-minute saliva weight (3MSW) from baseline to weeks 4 and 8.
- Secondary outcomes include assessments using the Drooling Severity and Frequency Scale and the Functional Oral Intake Scale.
Conclusions:
- This study aims to provide crucial evidence for PSS treatment strategies.
- Results may elucidate whether PSS is primarily due to increased salivary production or impaired swallowing function.

02:07Blind Procedures
Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which child was...
01:11Blinding
Blinding is a commonly used method of not telling participants which treatment a subject is receiving. Blinding is a critical part of a randomized control trial or RCT. It reduces the bias that affects the results. In an RCT, blinding is used in the form of a placebo. A placebo effect occurs when untreated subjects falsely believe they have received the treatment and report improved symptoms. A placebo or a dummy treatment is administered to subjects to negate the bias caused by such an effect.
