Welcome to Progressive GaitWays…

“…the current demand for ‘evidence’ as a justification for intervening overlooks the shortfall of evidence and discourages the emergence of clinical evaluation, skill building, and science-based innovation.”

The Tyranny of Evidence…

Beverly Cusick, PT, MS, NDT, COF/BOC pushes back on the current culture of dependence on single-focus, short-term clinical studies that ignore the complex morbidities of cerebral palsy – and the sciences that address them.

The W-Sitting Controversy: Evidence and Science

A growing number of physicians and orthopedists are advising parents to let their children W-sit because it is comfortable for them. In this 90-minute pre-recorded webinar, Beverly Cusick investigates the evidence and the science supporting both this and the more common practice of discouraging habitual w-sitting.

Introductory Pricing: $45 thru August 31st!

The first program in the series The Golden Rule of Managing Pediatric Orthopedic and Motor Development is now available for your professional development – at your convenience, in a pre-recorded webinar!

Program 1: Early Postural Control Acquisition

In this hour-long webinar, Beverly (Billi) Cusick reviews key biomechanical and sensory-motor aspects of early postural control acquisition – the essential foundation for building competent limb use and movement skills. She then demonstrates her “golden rule” concept with two clinical cases, and provides a detailed Q&A segment based on the discussions from the original live webinar.

In conclusion, Ms. Cusick traces the timeline, mentors, and influences that led her to the development of the Golden Rule – a valuable review that ‘connects the dots’ between the contributions of numerous well-known pioneers in physical rehabilitation.

Kudos for Program 1:

I took a course from Billi over 20 years ago (Biomechanics) and it transformed my practice.  Love how she integrated  all the  approaches (NDT, Sahrmann, Tschnarter etc..). Excellent information with clear application, and the science behind the art of postural control facilitation. It was concise, easy to follow, and packed full of golden nuggets. I actually bought Kathleen Porters book and will be sharing it with coworkers at the clinic including office staff!

Enjoyed the historical approach with references to the scientific basis behind the techniques. Good reminder of finding the balance between stability and mobility in order to enhance function.

Program 2: Expanding Postural Control into Movement

In Program 2, Ms. Cusick discusses the biomechanical and somatosensory aspects of the developing infant’s progress after stabilizing the body center of mass in prone and supine positions. In this next phase of early movement acquisition, lying leads to rolling and body weight is displaced in the frontal plane and elevated off the surface into quadruped position. The instructor’s golden rule is applied in suggested biomechanical and somatosensory strategies for remediating deficits.

Attendees gave Program 2 a ‘thumbs up’:

It’s very difficult to get clear, concise information regarding infant motor development and I really appreciate the quality of information as well as the convenience of the presentation type.

Billi is a wealth of knowledge which she shares in a clear, concise and clinically applicable way… The webinar allows learning in 1 hours chunks of time, with the opportunity to watch again for the week that follows. The handout follows the slides exactly and can be downloaded ahead of time to maximize learning.

An Open Letter to Caretakers and Therapists for Children with Diplegic CP

BCusick_OutsideProgressive GaitWays president and founder Beverly (Billi) Cusick writes:

“I’ve seen hundreds of families of children with diplegia, in consultation sessions in which I routinely undertake an orthopedic assessment and evaluate postural control, movement strategies, and existing orthoses. Common denominators have emerged that appear to operate to contribute to common problems of contracture development and recurrence, and to diminishing movement skills so often seen with advancing age in children with diplegia.

“I’ve composed the attached letter for caretakers and therapists of children with diplegia to bring them together in their understanding of the sources of many common musculoskeletal problems, and of the fundamental skills and strategies that are needed for effective remediation.”

Clinicians are welcome to download and share this letter with their colleagues, clients, and prescribing physicians.

Developmental Orthopedics of the Trunk & Lower Extremity @ Wee Care Therapy, Ltd.
Apr 11 all-day

Developmental Orthopedics of the Trunk & Lower Extremity:

A Review of Operating Processes with Implications for Management

Saturday, April 11, 2015
Registration:  7:30 am
Time:  8:00 am – 5:30 pm
Cost:  $195.00 (Price includes an assessment kit valued at $65)
Contact Hours: 7.25
IL EI: Pending Approval

Presented by:
Beverly Cusick, PT, MS, NDT, COF

Hampton Inn & Suites
8936 Calumet Ave
Munster, IN  46321

Target Audience:
Clinicians who are likely to work together to maximize physical function as a rehabilitation team, including PT, OT, Orthotists, Rehabilitation Physicians, and Orthopedists.

Course Level:
Intermediate- pre-course readings are assigned

Seminar Description:
This introductory program features an overview of the processes that contribute to pediatric orthopedic development, including the following:

Skeletal modeling mechanisms and influences.
Therapeutic limits on influencing the skeletal modeling process.
The influences of the biomechanics of ideal neonatal alignment on modeling the spine and lower extremity joints and on postural control acquisition.
The roles of postural control and massed practice on the orthopedic and functional development.
Developmental changes in muscle and connective-tissue extensibility.
Common errors of lower-extremity skeletal modeling in children with CNS dysfunction.
Strategies for optimizing somatosensory input, postural alignment, and postural control.
Using musculoskeletal assessment findings to gauge effectiveness of therapeutic management.

These principles are applied to pathomechanics commonly observed in children with hypotonia, cerebral palsy, excessive foot pronation, and intoed gait. The content presented in this program is considered fundamental to any (future) discussion of the specific features of orthopedic trunk and lower extremity development.

Seminar Objectives:

Participants will:

Distinguish between skeletal maturation and skeletal modeling.
Distinguish between mechanisms of strain and load, and apply this distinction to the “Golden Age.”
Describe the modeling effects of compression, tension, and loaded torque strains.
Describe the typical developmental changes that occur in spinal and lower-extremity alignment.
Describe the normal sequential acquisition of antigravity muscle function in the torso.
Relate normal neonatal soft-tissue constraints to the development of spine curves.
Discuss the role of somatosensory input in postural control and movement skills acquisition.
Describe the ideal features of weight distribution on the foot segments in standing position in infants, preschoolers, and adults.
Relate standing foot, spinal, and pelvic alignment to body weight distribution onto the feet and to muscle recruitment strategies needed to maintain postural control.
Discuss the normal emergence of R1 (first catch) end range of motion in the lower-extremity muscles.
Differentiate between spasticity and soft-tissue adaptation to chronic, tonic muscle recruitment.
Describe the evidence of a history of routine muscle recruitment strategies in range of motion findings.
Given the presence of excessive femoral torsion in a 9-year-old boy, explain the decision to defer corrective efforts to an orthopedic surgeon.
Explain the rationale for lifting under the heel and allowing the ankle to align in plantarflexion in the presence of equinus deformity.
Suggest strategies for delivering massed practice in improved postural alignment.
