I don't see how acupuncture can have any effects except placebo or spontaneous recovery since energy meridians have never been proven to exist.

Abstract
Acupuncture
is one of the main healing arts in Oriental medicine. It has long been
used in East Asian countries, including Korea and China, and is thought
to be an effective alternative treatment for various neurological
diseases. The therapeutic effects of acupuncture come from inserting a
needle at specific acupoints on the body surface, with subsequent
delivery of stimulation via manual rotation or electric pulses
(electroacupuncture, EA). In various neurological disease models,
peripheral nerve stimulation using acupuncture or EA may have protective
effects on neural tissues by increasing expression of neurotrophic
factors (NTFs), such as brain-derived neurotrophic factor and
glial-derived neurotrophic factor, in the central nervous system,
especially the brain. In addition, acupuncture may contribute to
recovery from functional impairments following brain damage by
encouraging neural stem cell proliferation, which is active at the
initial stage of injury, and by further facilitating differentiation.
Hence, acupuncture may act as a stimulator activating peripheral nerves
at specific acupoints and inducing the expression of various NTFs in the
brain. Subsequently, NTFs induced by this treatment trigger autocrine
or paracrine signaling, which stimulates adult neurogenesis, thereby
exerting therapeutic effects on functional impairments in neurological
diseases. Acupuncture may offer an alternative treatment that promotes
adult neurogenesis through the expression of NTFs in the brain. It may
also have synergistic effects when combined with pharmacological
interventions, again facilitating neurogenesis. This review examines
recent studies concerning the effects of acupuncture and EA on adult
neurogenesis associated with NTF expression in neurological diseases, in
particular stroke, Alzheimer’s disease, and Parkinson’s disease.
