A prehension orthosis with a pneumatic actuator has been developed to compensate for the disability of cervical cord injury patients and support their daily activities. One major feature of this orthosis is that the user can continually pinch or hold a target object using a finely adjusted finger force. The movement and force applied to the fingers can be controlled by continuous instructional signals fromthe user through the activity of a command muscle, which is selected from among the muscles without functional impairment in the user’s body. The level of muscle activity can be obtained by using an original sensor that detects the hardness of the target muscle through contact with the skin. The level of muscle activity can be estimated by the hardness information of the muscle. This sensor is easily fixed to a user’s body by using an elastic belt and even works over clothing. Therefore, the user can wear the system very easily. This feature allows the system to be very user friendly. Users can handle fragile objects such as an egg or sculpted-glass by using this prehension orthosis because of its finger force control function. Excellent dexterity in the finger force control has been demonstrated through evaluation tests conducted with various subjects, including a spinal cord injury patient.

Early surgical treatment for traumatic spinal cord injury (SCI) patients has been proven to yield better improvement on neurological state, and widely practiced among surgeons in this field. However, it is not always affordable in every clinical setting. It is undeniable that surgery for chronic SCI has more challenges as the malunion of vertebral bones might have initiated, thus requires more complex operating techniques. In this case series, we report 7 patients with traumatic SCI whose surgical intervention is delayed due to several reasons. Initial motoric scores vary from 0 to 3, all have their interval periods supervised between outpatient clinic visits. On follow up they demonstrate significant neurological development defined by at least 2 grades motoric score improvement. Physical rehabilitation also began before surgery was conducted. These results should encourage surgeons to keep striving for the patient’s best interest, even when the injury has taken place weeks or even months before surgery is feasible because clinical improvement for these patients is not impossible.

The Memokath stent has been used in spinal cord injury patients as a reversible alternative to external urethral sphincterotomy, but the stent has a finite lifetime of <2 years before failure in the majority of patients. We report an unusual case of a spinal cord injury patient in whom memokath stent was functioning for almost 14 years. The long life span of the Memokath in this patient was probably due to this person's habit of drinking around 5 l of fluids a day. Large fluid intake resulted in high urine output and, consequently, deceased the risk of urine infections and delayed formation of encrustations around the stent. Although this case represents an unusual length of time for a Memokath stent to have been in place and functioning, caution should be exercised against the long-term use of Memokath stents. Memokath stents do not get absorbed into the mucosa unlike urolume stents and, therefore, are prone to stone formation. Further, Memokath stents have not yet been approved in the U.S. either for bladder outlet obstruction or detrusor-sphincter dyssynergia. This case is also a reminder to health professionals that if a tetraplegic patient, in whom a Memokath stent has been deployed for treatment of detrusor-sphincter dyssynergia, presents with autonomic dysreflexia, encrustations blocking the lumen of the stent or calculus formation around the stent should be considered as possible reasons for autonomic dysreflexia.
