2.2.3. Type of Intervention Used in the Experimental and Control Groups

The experimental group intervention consisted of different types of acupuncture treatment combined with CM. In the control group, we selected L-dopa, which has been an effective gold standard dopamine-based medication for movement symptom management for approximately 60 years, as an essential medication for the control group (CM) [22,23]. Studies were included if the combination of L-dopa and other drugs was equally applied to the acupuncture and control groups. However, studies in which treatment medication therapy was performed only with other drugs without L-dopa were excluded. Acupuncture treatments included electroacupuncture (EA), MA, or BVA. We excluded combined acupuncture treatments, such as EA + BVA or MA + BVA, to evaluate the therapeutic effect of each acupuncture intervention type. The intervention in the control group was defined as CM therapy alone or CM + sham acupuncture treatment. We did not restrict the duration, dosage, or frequency of treatment.
