Sagittal plane biomechanics. American Diabetes Association.

During walking, the center of body mass must pass from behind the weightbearing foot to in front of it. For this to take place, the foot must function as a sagittal plane pivot. Because the range required for this motion is approximately five times as great as both frontal and transverse plane motion, its evaluation should become an essential part of a podiatric biomechanical assessment. Lack of proper sagittal plane motion and its sequelae are described.

Manipulation method for the treatment of ankle equinus.

Ankle equinus is a well-known clinical entity that has previously been shown to compound a variety of foot and ankle conditions. Treatments for this disorder have included surgery to lengthen the Achilles tendon and daily stretching. This article describes a method of manual manipulation that can immediately and substantially increase ankle joint dorsiflexion. Patients treated with manipulation in the current study demonstrated nearly twice as much dorsiflexion motion as that demonstrated by patients in a prior study who were treated with a 5-minute daily stretching program for 6 months.

Chronic low-back pain and its response to custom-made foot orthoses.

A new approach to treating chronic low-back pain with custom-made foot orthoses was investigated. The Quebec Back Pain Disability Scale was used to objectively assess the functional disability of 32 subjects at different times. Subjects in this prospective study experienced more than twice the improvement in alleviation of pain, and for twice as long, compared with subjects in a study using traditional back-pain treatment. The authors believe that the findings of this study may provide a new method by which patients with chronic low-back pain can be evaluated and treated.

Gait style as an etiology to chronic postural pain. Part II. Postural compensatory process.

The body is designed to pull the center of mass over a single pivotal site formed by dorsiflexion of the first metatarsophalangeal joint. If this response dorsiflexion motion is blocked by functional hallux limitus, then the kinetic energy, which is created for this motion, must somehow be dissipated. The process by which this dissipation occurs creates a specific pattern of compensations which, in the past, has been seen as primary motions unrelated to sagittal plane blockade. These compensatory motions are described along with a brief section concerning the methods of treatment.

Gait style as an etiology to chronic postural pain. Part I. Functional hallux limitus.

A common, but locally asymptomatic and therefore rarely recognized functional inability of the first metatarsophalangeal joint to dorsiflex strictly during gait is described. Normal motion is present in this joint during nonweight-bearing examination; therefore this is referred to as functional hallux limitus. Since this joint forms the pivot about which the entire body advances during each step, this disturbance in function, when repeated thousands of times on a daily basis, can alter foot and postural biomechanics. It can cause and perpetuate many chronic postural ailments, including lower back pain. When functional hallux limitus is specifically addressed in an orthotic treatment plan, 77% of long-term chronic postural pain patients exhibit 50% to 100% improvement in their overall condition, in spite of failing previous therapy on their specific site of pain and never exhibiting any foot symptomatology.
