Clinical and single-photon emission computed tomography study of pure akinesia with freezing of gait

The clinical syndrome of pure akinesia (PA) is considered the third phenotype of progressive supranuclear palsy (PSP), and is characterized by freezing of gait and prominent speech disturbance without rigidity or tremor. It is frequently considered one of the dopamine resistant motor syndromes, and its pathophysiology remains unclear. We report a patient followed in the Department of Neurology of Razi Hospital, Tunisia, with PA with gait freezing (PAGF) with a frontal hypoperfusion on single photon emission CT and non-responsive dopa therapy. We discuss the clinical features of PAGF and efficiency of treatment options.

Einsatz des Ganglabors bei klinisch-orthopädischen Fragestellungen in der Kinderorthopädie

AIM OF THE STUDY

We point out multiple applications of a gait laboratory in solving different problems in the children's orthopaedic field. With typical examples we show how biometrical data of the gait laboratory can be helpful to solve problems in orthopaedic examinations.

MATERIAL AND METHOD

The range of questions to be solved in the gait laboratory differs from individual diagnostic examinations of a patient up to the control of devices in the functional use at the patient. As a typical example for the individual examination we show the gait analysis in a 14-year-old girl with idiopathic chondrolysis of the hip joint. The functional use of orthopaedic devices will be shown in youths with neuroorthopaedic diseases. As a very special question to the gait lab we describe the supply of children and youths with optimal sport shoes for running.

RESULTS

The biometrical measurement techniques generate exact data to solve individual diagnostic and therapeutic questions. Orthopaedic devices can be tested in their functional efficiency and quality. Special questions can be answered very flexible.

CONCLUSION

Diagnosis and therapy in orthopaedics and children's orthopaedics rely on exact data. However, details of the dynamics during movement are neither visible to the most experienced orthopaedic surgeon nor can they be documented by conventional diagnostic imaging procedures. The present technical potential of biometric assessment methods allow to precise and correct some empirical knowledge, they open a wide field of new applications in diagnostic and therapeutic examinations.

Locomotor therapy in neurorehabilitation

Gait rehabilitation is a major aspect of neurological rehabilitation. This review is on locomotor therapy by treadmill stimulation with partial body weight support evolving as a very promising treatment concept over the last years. It enables severely affected patients the repetitive practice of complex gait cycles and thus follows modern aspects of motor learning favoring a task-specific approach. Several studies have shown its potential in patients after stroke, spinal cord injury, M. Parkinson and cerebral palsy. An electromechanical gait trainer relieving the strenuous effort of the therapists and controlling the trunk in a phase-dependent manner is a new alternative.

The effect of foot orthoses on standing foot posture and gait of young children with Down syndrome

The purpose of this study was to determine if foot orthoses (FOs) immediately affected gait of children with Down Syndrome (DS) and excessively pronated feet. Subjects were 3--6 years old; 16 with DS and 10 without disabilities. Gait of children with DS wearing sneakers was compared with and without FOs and compared to gait of children without disabilities. Ankle moment, walking speed during stance phase, sneaker prints, center of pressure, and transverse plane foot angles were collected and compared. In standing, heel eversion was reduced when the children wore FOs (p=0.000). During gait the transverse plane foot angle decreased indicating more internal rotation with FOs (p=0.000). Trial-to-trial variability of pronation-supination index (p=0.0001), foot length contact (p=0.0001), transverse plane foot angle (p=0.0003), and walking speed (p=0.0001) all decreased with FO use. Trial-to-trial variability of normalized peak ankle moment (p=0.0001), and of phase of peak ankle moment (p=0.0001) increased when the children wore FOs.
