“In the present study, 8 healthy, older females with some signs of facial laxity followed a mechanically aided facial exercise program based on progressive resistance for 8 weeks…We found that biomechanical extensibility had decreased, which was quite consistent with the primary perception of the panelists that their facial skin had become firmer and more elastic.” —The Journal of Geriatric Dermatology “A Mechanically Aided Resistance Exercise Program for Sagging Facial Muscles” By Gary L. Grove, Ph.D., Stan W. Rimdzius, B.S., Charles R. Zerweck, Ph.D.

“15 healthy older females with some signs of facial laxity followed a mechanically aided facial exercise program based on progressive resistance for 3 months…by the end of the 3-month treatment period, highly significant differences were achieved.” Society for Investigative Dermatology “Changes in Facial Skin Biomechanics Due to a Mechanically Aided Resistance Exercise Program” By G. L. Grove, S. W. Rimdzius, M. J. Grove



“This paper describes a study on the physiological effects of an 8-week mechanically aided exercise program using the Facial-Flex® device …In general, the data of this study support the claim that the use of the Facial-Flex® device has a clear impact on speech-motor physiology”—”Oral-Motor Physiological Effects of an 8-Week Mechanically Aided Resistance Exercise Program” By Pascal van Lieshout, Ph.D., Arpita Bose, M.Sc., Aravind Namasivayam Kumar, M.Sc., University of Toronto, Graduate Department of Speech-Language Pathology, Canada *This is an excerpt from a manuscript submitted for publication to an international peer- reviewed journal

“The patient is a 57-year-old male with a 4- to 5-month history of hoarseness, hypernasality and strain with voice use…the Facial-Flex® made the speech therapy easier to complete and more successful. The patient has had improvement in vocal quality, strength stamina, pitch range and ease of use.”—“The Use of Facial-Flex® as an Adjunct to Speech Therapy in the Treatment of Voice Disorders: A Case Report” By Joseph R. Spiegel, M.D., Judith N. Creed, M.A., CCC-SLP, Kate A. Emerich, M.S., CCC-SLP

“Facial-Flex is a valuable instrument for improving oral muscle strength…Preliminary findings of this study suggest dramatic rehabilitation of facial musculature in a population for whom such improvement is essential. [Patients suffering from a stroke or idiopathic Parkinsonism] —“Recovery of Facial Muscle Strength in the Disabled Through a Mechanically Aided Resistance Exercise Program” By Judith Creed, M.A., CCC, SLP, Joseph R. Spiegel, M.D., Jesse Selber, B.A.

“After initial recovery from the last extensive surgical procedure, L.R. had persistent complaints of difficulty with mouth opening, pain with jaw motion during eating and poor articulation…After completing 3 weeks of the first interval of Facial-Flex use, the patient, her family members, and the treating speech pathologists noted improvement in motion of the right oral commissure and improvement in articulation. As she completed the second interval of Facial-Flex exercise, L.R. noted significant improvement in articulation and in her swallowing ability.”—“The Use of Facial-Flexas an Adjunct to Speech Therapy in Recovery from Extensive Oral Cavity Carcinoma” By Joseph R. Spiegel, M.D., Judith N. Creed, M.A., CCC-SLP

“Facial-Flex was used as an adjunct to traditional speech therapy in a population of school- age children being treated for articulation disorders. 133 children were chosen from a group of 1,200…All children demonstrated improvement of oral motor strength, with an average improvement of 467% in repetition index and 224% in closure time index. Eight children had a significant improvement in articulation attributable to Facial-Flex”—”Using Facial-Flex to Assist Treatment of Articulation Disorders”Supervised by: Judith Creed, M.A., SLP-CCC, Joseph R. Spiegel, M.D., FACS



“The dysfunction and palpation indexes individually do not show any improvement as a result of the treatment. But the craniomandibular index alone shows a statistically significant difference concerning the “improvements.”Temple University School of Dentistry “A Clinical Study of the Effects of Facial-Flexin Patients with TMD” By Zarrinnia K, Braun RJ, Straja SR (Presented at the Conference of the American Association of Orthodontists, San Diego)

“For the craniomandibular index, the general trend is for a positive “improvement” for the treatment group and virtually no improvement for the control group.”Temple University School of Dentistry “A Clinical Study of the Effects of Facial-Flex in Patients with TMD” By Drs. R. Braun and K. Zarrinnia

“We have had success in treating post-reconstruction and post-augmentation stiff upper lip with a therapeutic device [Facial-Flex] and treatment regimen. This therapy alleviated tightness and inability to smile. Also, the change in lip commissure-to-commissure distance in repose and when smiling improved after treatment.”—Plastic and Reconstructive Surgery Journal “Lip Service for the Stiff Upper Lip” By Barry M. Zide, M.D., James P. Bradley, M.D., Michael T. Longaker, M.D. *Reprinted with permission from the Institute of Reconstructive Plastic Surgery at New York University Medical Ctr. in the Plastic and Reconstructive Surgery Journal

“A study of the Facial-Flex® device called the Bite Assist Exerciser or BAE…The BAE was shown to be a safe, simple and efficient method of muscular exercise for TMD patients with a variety of diagnoses which included some form of muscular dysfunction…The utilization of the combination of the BAE device with the original Facial-Flex device may also help in the alleviation of muscular problems.” University of Maryland “Interim Report for Facial-Flex Corporation” By Edward G.
