[=OAG 1,01 3] If the operative terms in the administrative code definition of the practice of chiropractic are given their common meaning, it is clear that chiropractic practice, physical therapy practice and massage therapy practice may overlap under some circumstances. “Physical therapy” is defined by section 448.50(4) to be, in relevant part, “that branch or system of treating the sick which is limited to therapeutic exercises with or without assistive devices, and physical measures including heat and cold, air, water, light, sound, electricity and massage; and physical testing and evaluation.” “Physical therapy” is not further defined by administrative rule. “Massage therapy” is defined by section 440.98(4)(a) to be, in relevant part “the science and healing art that uses manual actions to palpate and manipulate the soft tissue of the human body.” Wisconsin Administrative Code § RL 90.02(7) repeats the statutory definition of “massage therapy.” “Manual action” is defined to include “holding, positioning, rocking, kneading, compressing, decompressing, gliding or percussing the soft tissue of the human body and applying friction to soft tissue.” Wis. Stat. § 440.98(2); Wis. Admin. Code § RL 90.02(5). One area of apparent intersection among the three disciplines is in their attention to the soft tissues of the body. For example, to the extent that a physical therapist or massage therapist provides hand massage to the soft tissue adjacent to a skeletal joint, the physical therapist or massage therapist makes an “adjustment” to that tissue – an action that is potentially also within the scope of chiropractic practice. Physical therapy and chiropractic also intersect in that both may address the alignment of the body. To the extent that a physical therapist teaches a therapeutic exercise by, e.g., aligning the patient’s pelvic girdle to change the patient’s balance point, or straightens the patient’s spine to demonstrate proper lifting technique, the physical therapist engages in an adjustment of the patient’s joints, within the common meaning of that term, and therefore performs an activity which may be within the definition of the practice of chiropractic.
[=OAG 1,01 4] Despite the apparent expansiveness of the procedures included within the definition of chiropractic practice, the intersections among chiropractic practice, physical therapy and massage therapy are limited in one crucial respect. Each of the activities within the definition of chiropractic practice must involve “the application of chiropractic science” in order to be part of the practice of chiropractic. The current definition of chiropractic practice recognizes that chiropractors do not have a monopoly on the application of therapeutic touch to the neck, back and joints, and recognizes that it is the application of chiropractic science which distinguishes chiropractic from other healing arts and sciences involving therapeutic touch. Thus, for example, if a specific type of therapeutic touch were administered by a physical therapist applying the principles of physical therapy science, or by a massage therapist applying the principles of therapeutic massage, those procedures would not be within the definition of chiropractic science, because neither would involve the application of chiropractic science, even if nearly identical physical motions were performed by a chiropractor. Terms such as “adjustment” and “manipulation” have a variety of appropriate meanings to various healing disciplines as the examples above demonstrate. Further efforts by the Chiropractic Examining Board to define the particular procedures described in your inquiry should focus on the unique, specific features of the discipline of chiropractic science.
The Legislature has recognized the possibility that chiropractic practice and physical therapy practice may overlap. Sections 446.02(10)(a) and 448.525(1) both provide that the Chiropractic Examining Board and the Physical Therapists Credentialing Board “shall jointly promulgate rules that establish the circumstances under which and the extent to which a chiropractor . . . may claim to render physical therapy or physiotherapy services within the scope of the practice of chiropractic.” Moreover, sections 446.02(10)(b) and 448.525(2) prevent either board from unilaterally promulgating rules defining the physical therapy practice of chiropractors. At the time this opinion is written, no joint rules have been promulgated. [=OAG 1,01 4-5] The courts and this office have also recognized that the disciplines of various health care professionals may overlap. In Kerkman, 142 Wis. 2d at 416, the court recognized that “[a]lthough chiropractors are permitted to use some medical tools when analyzing and treating a patient, this overlap does not transform the practice of chiropractic into the practice of medicine.” In 68 Op. Att’y Gen. 316 (1979), my predecessor concluded that a physician could advise a patient whether continued chiropractic care was necessary without engaging in the unauthorized practice of chiropractic, even though that advice may technically fall within the definition of chiropractic practice. That opinion considered the general law on litigated disputes between engineers and architects over the scope of their respective practices, quoting 5 Am. Jur. 2d Architects § 3 (68 Op. Att’y Gen. at 319-30):
[W]here either a licensed architect or a licensed engineer performed services which could properly be regarded as within the reach of the statute licensing his profession and also within the statute licensing the other profession, he performed such services under the statute under which he was licensed and was not affected by the fact that they came incidentally within the purview of the other licensing statute.
The opinion further stated (68 Op. Att’y Gen. at 320):
It is my opinion that a similar line of reasoning must be applied to chiropractors and physicians. In giving advice to patients, there is an overlap between what may properly be done by a chiropractor and a physician under their respective grants of statutory authority. In my view, a physician is given the latitude to perform services within his or her authority, whether those services overlap with professional services properly performed by a chiropractor, or other health care professional.
To find otherwise would be to place unreasonable restraints on the practice of medicine. As summarized by the court in Smith v. American Packing & Provision Co., 102 Utah 351, 130 P.2d 951, 955 (1942), "the mere fact that a licensed profession extends in some degree into the field of some other licensed occupation, does not require the licensee to have a license in each of the fields into which his profession may overlap, unless the statutes impose such requirement." Our statutes impose no such requirement. It is therefore my opinion that physicians may advise their patients whether or not continued chiropractic care is necessary. By so doing, physicians are not engaging in the unauthorized practice of chiropractic.
In the absence of a more specific explication of the operative phrases of the practice statutes involved – particularly, sections 446.01(2), 448.50(4) and 440.98(4)(a) – by the administrative rules each of the respective examining or credentialing boards or department is authorized to promulgate, my opinion is limited to the general proposition that physical therapists and massage therapists are not prohibited from performing the activities that are within their respective scopes of practice, even if those activities extend in some degree into the field of chiropractic practice.
[=OAG 1,01 6] Consistent with sections 446.02(10)(a) and 448.525(1), I urge the Chiropractic Examining Board to begin the legislatively-mandated process of promulgating joint rules with the Physical Therapists Affiliated Credentialing Board. I encourage both boards to sharpen the definitions of their respective practice areas, in order to give both chiropractors and physical therapists adequate guidance about the permissible scope of their respective practices.
