A 54-year-old man with poliomyelitis had been using a conventional, passive knee-ankle-foot orthosis (KAFO) with a drop ring lock knee joint for about 40 years. A stance control KAFO (SCKAFO) with an electromagnetically controlled (E-MAG) knee joint system was prescribed. To correct his gait pattern, he also underwent rehabilitation therapy, which included muscle re-education, neuromuscular electrical stimulation, strengthening exercises for the lower extremities, and balance training twice a week for about 4 months. Both before and after rehabilitation, we conducted a gait analysis and assessed the physiological cost index in energy expended during walking in a locked-knee state and while he wore a SCKAFO with E-MAG. When compared with the pre-rehabilitation data, the velocity, step length, stride length, and knee kinematic data were improved after rehabilitation. Although the SCKAFO with E-MAG system facilitated the control of knee motion during ambulation, appropriate rehabilitative therapy was also needed to achieve a normal gait pattern.

A 3-year-old girl had multiple anomalies compatible with Treacher Collins Syndrome (TCS). From the neonatal period, sucking was poor, making tube feeding necessary. Excessive saliva was retained in the oral cavity. Nasal leakage caused by the cleft palate was observed when she spoke. The initial videofluoroscopic swallow study (VFSS) showed a poor posterior bolus transit and nasopharyngeal regurgitation. A delayed swallow reflex and bolus stasis at the vallecular and pyriform sinuses were recognized. Based on the VFSS findings, the patient underwent palatoplasty at 20 months of age. At approximately 23 months of age, a follow-up VFSS was performed; poor posterior bolus transit, nasopharyngeal regurgitation, and delayed swallow reflex were not observed. Finally, the patient was able to eat ground or chopped foods and solid foods orally. We deem VFSS to be helpful in deciding the appropriate management of dysphagia in TCS.

To evaluate diaphragmatic motion via M-mode ultrasonography and to correlate it with pulmonary function in stroke patients.
This was a preliminary study comprised of ten stroke patients and sixteen healthy volunteers. The M-mode ultrasonographic probe was positioned in the subcostal anterior region of the abdomen for transverse scanning of the diaphragm during quiet breathing, voluntary sniffing, and deep breathing. We analyzed diaphragmatic motion and the relationship between diaphragmatic motion and pulmonary function.
All stroke patients had restrictive pulmonary dysfunction. Compared to that exhibited by control subjects, stroke patients exhibited a significant unilateral reduction in motion on the hemiplegic side, primarily during volitional breathing. Diaphragmatic excursion in right-hemiplegic patients was reduced on both sides compared to that in control subjects. However, diaphragmatic excursion was reduced only on the left side and increased on the right side in left-hemiplegic patients compared to that in control subjects. Left diaphragmatic motion during deep breathing correlated positively with forced vital capacity (rho=0.86, p=0.007) and forced expiratory volume in 1 second (rho=0.79, p=0.021).
Reductions in diaphragmatic motion and pulmonary function can occur in stroke patients. Thus, this should be assessed prior to the initiation of rehabilitation therapy, and M-mode ultrasonography can be used for this purpose. It is a non-invasive method providing quantitative information that is correlated with pulmonary function.
