CLT Recertification Program

The Comprehensive Recertification Program is designed for completion in two independent parts, which can be satisfied at the pace and in the preferred order of each participant. Total continuing education, 48 hours. Participants of both elements will earn a current CLT Recertification “Certificate of Completion” from the Norton School. Completion of both portions is elective and each can be applied independently towards LANA recertification individually.

The Online Recertification Course (32 hours, accessed on this page)
This online course series is a complete Theoretical review of content covered in the full CDT Certification Program offered by the Norton School of Lymphatic Therapy. The program is designed in sections to allow each student to absorb the information at a comfortable pace. If the goal of home study is thorough preparation for the Lymphology Association of North America (LANA®) Examination®†, or to meet the requirements of LANA recertification, this program includes all necessary information. Completion of this online portion awards students a “Theoretical Recertification” Certificate of Completion.

The Techniques Review for CLT’s Course (16 hours, live classroom instruction)
see tab on homepage for course description and schedule of course locations. Completion of this live instructional program awards students a “Practical Recertification” Certificate of Completion.

Tuition for the CLT Recertification Program is $495.00

Lecture Content

Section 1: Anatomy

This section covers the complete structure of the lymphatic system including lymph vessels (capillaries, precollectors, collectors, trunks, and ducts) lymph nodes, the superficial and deep systems, lymph fluid, absorption, transport, volume, immune function, regional node aggregations, territories, watersheds, anastomotic connections, and historical overview of the science of lymphology.

Section 2: Physiology

This section's content includes: diffusion, osmosis, colloid osmotic pressure, ultrafiltration, reabsorption, microcirculation, peripheral resistance, active and passive hyperemia, Starlings Equilibrium, interstitial pressure, colloid osmotic pressure of the interstitium, lymphatic insufficiencies (dynamic, mechanical, combined), lymph load, lymph time volume, transport capacity, high and low protein edema, genesis of lymphedema, venous edema, and phlebo-lymphostatic edema.

Section 3: Manual Lymph Drainage Theory

This section is a study of manual lymph drainage from origin and history to application in treatment of lymphedema. It covers: contraindications, indications, precautions, mechanics of technique, principles of delivery, effects on anatomical and physiological systems, Vodder technique, and strokes (stationary circle, pump, rotary, scoop).

Section 4: Compression Bandage Theory

This section's concepts include: Law of LaPlace, compression gradient, short stretch vs. long stretch bandaging, principles of lymphedema bandaging, contraindications to compression, indications, precaution, effects, mechanical properties, applications to various diagnoses, techniques to generate lymphedema-appropriate bandages, spacing, tension, layering, graduated widths, review of all materials, trade names, and rationale for use.

Section 5: Compression Garments

This section covers medically correct gradient support stockings, sleeves, various configurations, flat knitting, circular knitting, cut and sew machining methods, compression classifications, standard classes for various diagnoses, custom made garments, selection criteria for diagnosis, and tips for developing better outcomes.

Section 6: Diagnosis

This section delivers broad information covering the full scope of lymphedema related topics such as incidence, classification, staging, primary and secondary types, dysplasias of the lymphatic tissue (hypo, hyper, aplasia, Kinmonth syndrome), Milroys and Meiges disease, genetic causes, mechanical insults to the tissues, and differential diagnosis of venous, lymphatic, combined edema, cardiac edema, PTS, CRPS.

Section 7: Therapy

In this section the treatment forms available for lymphedema are discussed including: pneumatic compression pumps, surgical interventions such as liposuction, debulking, skin flaps, transplantation, Complete Decongestive Therapy, history of CDT, two phase therapy, modalities of CDT, expected outcomes, treatment planning, and efficacy of treatment.

Section 8: Complication of CDT

This section discusses typical complicating factors associated with clinical delivery of lymphedema therapy such as scars, hyperkeratosis, papillomatosis, skin folds, lobular outgrowths, elephantiasis, hygiene, cellulitis, contact dermatitis, fungal infections, malignant lymphedema, recurrent cancer phenomena, radiation changes, fibrosis, teleangiectasia, and collateral veins.

Section 9: Applications of CDT

CDT is appropriate for other pathologies. This section's content includes: adaptations for the treatment of chronic venous insufficiency, post-thrombotic syndrome, phlebo-lymphostatic edema, lipedema, lipo-lymphedema, post-traumatic edema, post-surgical edema, compression considerations, manual lymph drainage and garment considerations, compression classes, materials selection, and plan of care including intensive and homecare phases of CDT.

Section 10: Lymphedema Bandaging: Video Practical Instruction

This course provides students with the opportunity to view essential bandaging skills in a comprehensive visual format. The concepts presented include: tensioning, molding, spacing, graduated layering, precision, positioning, and logical progression. This exposure is extremely valuable as much of the skill set developed for lymphedema bandaging is derived from observation, palpation, and kinesthetic awareness. Each compression-bandaging component is approached with a standard layering protocol based upon the performance properties of each material coupled with extensive clinical impression.

Section 11: MLD Strokes & Sequences

This course provides a complete review of the 4 Vodder MLD strokes and their application in various intact and non-intact upper and lower extremity treatment sequences.

Section 12: Compression Garment Measuring

Custom garment measuring and fitting is a skill that rounds out every Certified Lymphedema Therapist's knowledge base. During this video program Steve Norton demonstrates the steps involved in measuring for flat-knit custom gloves, arm sleeves, shoulder caps, knee-high garments, thigh-high garments, pantyhose, and toes caps. Since most techniques and points of measure are universal among all garment manufacturers, this course provides a solid foundation that can be applied to most fitting scenarios.
All courses are written and narrated by Steve Norton and are followed by an exam based on the course's material content.

Reference Articles

The articles selected from the Norton School E-Reference Library function as important contributing references to the field of lymphedema treatment and lymphology and cite an evidence-base that is universally supported as fact. Students should read these articles but will not be tested on their content during the course.
