Thirty-three cases of infantile spastic
hemiplegia
have been treated surgically for wrist deformity in flexion, pronation and ulnar deviation. The authors used Green's technique in most of the cases (transplantation of flexor carpi ulnaris to the extensores carpi) either in isolation or in association with lengthening of the pronator teres. The indications for surgery are given and the details of surgical technique and postoperative care are described. The complications are described and the factors affecting prognosis are analysed. Half of the cases had good or excellent results; five were failures.

A simple experimental procedure administered by parents was used to study the effects of variation of reinforcement on performance of a motor skill by a 7-yr.-old retarded male. Owing to
hemiplegia
this subject has a very restricted range of movement in his left hand. The task required him to use his left hand to place wooden cubes within squares drawn on a paper sheet. Factors varied were type of reinforcer (3 consumables), schedule (continuous, fixed ratio and variable ratio), and frequency of reinforcement. Administration of variable ratio delivery was proceived as an enjoyable game by the subject who produced his best performances under this condition. Functional analyses (mini-experiments) should include type of reinforcer and form of delivery.

The relationship of preinjury left-hand dominance for motor performance to postinjury distal motor skills following penetrating brain wounds in patients without overt
hemiplegia
was examined. We studied 13 controls, 13 right-hemisphere brain-damaged patients, and 11 left-hemisphere brain-damaged patients on motor tasks measuring reaction time, strength, and coordination. Our results indicated that no persistent deficits were seen on distal motor tasks in left-handed adults who suffered a penetrating brain wound. These findings are compatible with the relative sparing of persistent neuropsychological deficits in left-handers following brain damage.

The authors report the results of surgical treatment of the equinus deformity of the foot in adult
hemiplegia
performed on 23 patients with a long term follow-up for 20 of them. Surgical treatment required two phases. Firstly, a spasticity correction by scopiform neurotomy of the posterior tibial nerve: this operation had to be done 14 times because of the importance of the spasticity. Secondly, a phase of truly orthopaedic surgery which involved successively, a treatment of the equinus deformity by lengthening of the Achilles tendon, a restoration of the dorsal flexion by anterior muscle transfer and some complementary operations on the forefoot. An astragalo-scaphoid arthrodesis was associated in the 13 most recent cases. Results were subjectively judged very good or good for 17 patients. Objectively, walking appliances have been reduced, gait was more secure and a greater autonomy has been reached. However, the goals of this surgery are limited as it has no incidence on central interferent lesions and neuropsychological troubles resulting from brain damage. The quality of the result is, in other respects, conditional upon the gait pattern of the whole limb, particularly upon the importance of the flexion of the knee during the step cycle.

The purpose of this study was to examine the pattern of attentional deficits in children with right and left hemiplegic cerebral palsy. Unilateral neglect and visuospatial deficits are common findings following right brain injury in adults. It has been suggested by some that children may show a similar pattern. Children were tested on several paper-and-pencil measures of neglect. It was hypothesized that (a) on the left side of the page, children with left
hemiplegia
(right hemispheric damage) will score significantly lower than both the control group and the right
hemiplegia
group and (b) on the right side of the page, there will be no significant difference between the control group and the right and left hemiplegic groups. Participants included 32 children with cerebral palsy, 15 with left
hemiplegia
, 17 with right
hemiplegia
, and 32 matched controls. The ages ranged from 5 years 10 months to 12 years 6 months; all had normal intelligence. Inventories included 3 subtests of the Conventional part of the Behavioral Inattention Test, the Mesulam Symbol Cancellations tests, and the Rey Osterrieth Complex Figure, copy and recall. Analysis indicated that children with left
hemiplegia
scored significantly more poorly than controls on seven of the eight measures on the left side of the page, but they did not consistently score more poorly than children with right
hemiplegia
. Moreover, the poorer performance of the children with left
hemiplegia
was not specific only to the left side of the page; they also scored significantly lower than the controls on five of the eight measures on the right side. These findings suggest that children with left
hemiplegia
may have relatively greater attentional and perceptual problems than children with right
hemiplegia
, but they do not clearly indicate a left unilateral neglect. Results also indicate that children with right
hemiplegia
have attentional and perceptual problems relative to controls, particularly on the more complex tasks of high demand.

We describe a case of a brain-damaged patient who had a peculiar bodily illusion which could not be labelled an hallucination but seemed somatognosically and phenomenologically similar to the phantom limb without amputation. The patient, who showed left
hemiplegia
, felt a third upper limb (without seeing it) which he himself defined as "spare." The spare limb was not deformed; it could be moved and controlled by the patient, and there was no sensation of pain. The patient did not show psychopathological or cognitive disorders. A possible interpretation of the phenomenon is as a "phantom movement" of the paralysed limb: the mental representation of the movement of the limb was dissociated from the bodily representation of his own limb and so was still present in his consciousness despite the paralysis.

A recently published case report of a supernumerary phantom limb in a man with left-sided
hemiplegia
did not take note that this phenomenon has been extensively documented in the neurological literature for well over 100 years. The present comment provides a brief introduction to the clinical and experimental approaches to supernumerary phantom limbs. It also emphasizes the theoretical importance of this condition for understanding the neurological mechanisms subserving the experience of having a body.

The aim of this study was to assess whether persons with hemiparesis will yield statistically reliable test-retest tracking performance on a procedure using limb-generated, compatibly displayed, myoelectric video feedback. A convenience sample of 50 inpatients and outpatients with upper extremity involvement of at least six months were recruited. 30 had hemiparesis and had both upper extremities tested. 20 had
hemiplegia
and had the nonparetic upper extremity tested. Tracking skill was measured as mean tracking error. Repeated measures analysis of variance yielded statistically significant effects of main factors: Response mode, Cursor Feedback, and Session. Extremity tested was not significant. Performance with involved limb, uninvolved limb, isometric mode, and isotonic mode all yielded positive rest-retest correlations. The reliable range of tracking error obtained from subjects with hemiparesis performing a task requiring modulation of compatibly displayed myoelectric output supports the therapeutic rationale for employing compatibly displayed video feedback in the rehabilitation of motor control.

Both hand and finger sensory perception and motor abilities are essential for the development of skilled gestures and efficient bimanual coordination. While finger dexterity and finger sensory perception can be impaired in children with cerebral palsy (CP), the relationship between these two functions in this population is not clearly established. The common assumption that CP children with better sensory function also demonstrate better motor outcomes has been recently challenged. To study these questions further, we assessed both finger dexterity and finger gnosia, the ability to perceive one's own fingers by touch, in groups of 11 children with unilateral (i.e., hemiplegic CP) and 11 children with bilateral spastic CP (i.e., diplegic CP) and compared them with typical children. In our sample, children with
hemiplegia
exhibited finger dexterity deficit in both hands and finger gnosia deficit only in their paretic hand. In contrast, children with diplegia exhibited finger gnosia deficits in both hands and finger dexterity deficit only in their dominant hand. Thus, our results indicated that children with spastic
hemiplegia
and diplegia present different sensory and motor profiles and suggest that these two subgroups of CP should be considered separately in future experimental and clinical research. We discuss the implications of our results for rehabilitation.
