Ultrasound biofeedback for speech training. Instrumentation and preliminary results.
Real-time ultrasound scanning was employed as biofeedback therapy to correct a persistent articulatory speech defect in a subject. The subject continuously imaged her tongue with a transducer placed submentally. During a speech exercise, the subject could compare her tongue's positioning and movement with an ultrasound image showing the correct tongue placement prerecorded onto video tape by a speech therapist. Preliminary results suggest that this technique could be a valuable addition to speech therapy.

The evaluation and prediction of impact forces during landings.
The investigation of impact force attenuation during landings may help identify performance strategies. The purpose of the study was to evaluate the effects of height (three), distance (three), and technique (three) on impact forces during landings. Three male volunteer subjects were filmed while performing three right foot landings onto a force platform for each combination of height, distance, and technique for a total of 81 trials per subject. Between- and within-subject three-way ANOVAs and three regression models (mechanical, biomechanical, refined biomechanical) were computed on the dependent variables of first (F1) and second (F2) maximum vertical force. Results of the between-subject ANOVAs indicated significant (P less than 0.05) height, distance, and technique main effects for F1 and a height x technique interaction for F2. The within-subject ANOVA results identified unique models for each of the three subjects. The biomechanical regression model exhibited the best predictions of F1 and F2 for S1 (81.0 and 72.0% explained variance, respectively), while the refined biomechanical model accounted for 83.4, 81.3, 80.9, and 88.0% of the F1 and F2 variances for S2 and S3, respectively. In conclusion, the within-subject results identified unique individual landing strategies that were masked by the group analyses suggesting that caution be exercised in using between-subject analysis techniques.

Tremor in otosurgery: influence of physical strain on hand steadiness.
BACKGROUND: The microscopically small middle ear structures require the otosurgeon to have a steady hand because instrument stability is a critical factor for a successful microsurgical procedure. Hand steadiness is mainly influenced by the tremor movements of the hand. The aim of this study was to measure hand tremor under simulated microsurgical conditions and to estimate the influence of different kinds of physical strain (e.g., physical exertion and hand exercise), as well as food abstinence and coffee consumption. Further, the effect of one-or two-handed manipulation and microsurgical experience was investigated. METHODS: The hand movements of 16 adult subjects were assessed during a defined manual manipulation using a stapes model to simulate microsurgical procedures. A laserinterferometric-based displacement technique was developed to measure tremor amplitude and frequency, as well as maximum displacement, to evaluate the subjects' fine motor skills. RESULTS: The mean tremor frequency across all measurements was 8.1 Hz and did not show any dependence on different kinds of physical strain. Two-handed manipulations showed significantly lower tremor amplitudes than one-handed performances. Tremor amplitude and maximum displacement did not change after hand exercise, food abstinence, and coffee consumption. However, after physical exertion, a significant increase in the tremor amplitude was found. Subjects with advanced microsurgical experience showed smaller tremor amplitudes for one-handed runs. CONCLUSION: The tremor data are interpreted as a recommendation to avoid physical exertion before microsurgery. In cases of absolute necessity for hand steadiness, two-handed manipulations are preferable. Further, hand steadiness might be improved by microsurgical training and experience.

Treatment and rehabilitation in vestibular neuritis.
During the acute phase, symptomatic treatment is practically the only option, and a wide variety of drugs are available. For years, much has been focused on the possibility of using corticosteroids in the treatment of vestibular neuritis. Clearly, if we suspect an inflammatory cause, a treatment that reduces that inflammatory process would, if not reduce the severity of the attack, at least help recovery. If the different studies on this matter failed to concord in many aspects, they do however agree that the use of corticosteroids in the acute phase entails long term beneficial effects for the recovery of vestibular function and allows for a better vestibular compensation. The second part of the treatment is the rehabilitation. In my experience most of the patients undergo a spontaneous vestibular compensation in a short time. Nevertheless, some exercises of visual fixation while the patient is still bed-ridden, can accelerate the recovery process. Those patients, in whom certain instability persists, who are too anxious after their experience or those who will demand this type of treatment, are candidates to undergo a rehabilitative vestibular program. In this paper I will comment on the instrumental and non-instrumental techniques that I use in my daily practice.

Treatment of condyle fracture caused by mandibular angle ostectomy.
A prominent mandibular angle is considered to be unattractive in Asian countries because it gives the face a square and muscular appearance. Successful correction by angle ostectomy has been reported, but one of the serious complications of angle reduction ostectomy is fracture of the mandibular condyle. If the ostectomy line is misdirected vertically, the condyle may be fractured. The authors experienced two cases of condylar fracture during angle reduction. Case 1 was a pulled-out condylar fracture, where an L-shaped miniplate was then attached by external approach, and intermaxillary fixation (IMF) with arch bar was used on postoperative day 14. With release of the IMF, a systematic approach for a jaw-opening exercise was begun. On postoperative day 21, the elastics were placed to assist in guiding protrusion of the mandible anteriorly 24 hours a day. After postoperative day 28, it was possible to completely abandon daytime elastic fixation. The exercise was modified to lateral movement. Case 2 was green-stick condylar fracture, with the IMF with arch bar applied on postoperative day 10. After releasing the IMF, the exercise involved the daily use of several tongue blades, and range of motion increased by wedging additional blades until postoperative day 21. More aggressive stretching was continued with 22 blades on postoperative day 28. On the removal of the arch bar, the occlusion was stable and followed by more aggressive stretching and physical therapy. Both cases were successfully restored and had good results. The authors believe the exercise protocols and algorithms they used may serve as a standard procedure of treatment in condylar fracture caused by angle ostectomy.

[Functional dystonia in musicians: fundamental principles of the rehabilitation].
The basic principles of rehabilitation of dystonia in musicians are designed to restore overall functional movement, but must also take into account the musician's often obsessive and anxious metal state. Rehabilitation is based on fundamental postural physical education and movement physiology. It must also develop a language to explain the dysfunction and to make it acceptable to the patient. The exercises themselves become the basis for a new behaviour. More than just a rehabilitation technique, we have tried to develop a personalized "self-correction" which could be the basis for real prevention.

Tracking retinal motion with a scanning laser ophthalmoscope.
The vast majority of people with low vision retain some functional vision to perform everyday tasks. To study the effectiveness and efficiency of the visual tasks performed by people with low vision, knowing the movement patterns of their preferred retinal locus (PRL) used for fixation, saccade, and pursuit is critical. The scanning laser ophthalmoscope (SLO) has been used to acquire retinal images while a subject is performing a visual tracking exercise. SLO data has traditionally been analyzed with the use of manual techniques that are both time-consuming and prone to errors due to operator fatigue. To improve the speed and accuracy of the analysis of retinal motion from SLO image sequences, we developed an automated image processing technique and tested it using MATLAB(TM) (The MathWorks, Natick, MA) software. The new software technique was experimentally tested on both normal- and low-vision subjects and compared with the results obtained using manual techniques. The findings indicate that the new technique works very well for most subjects, fairing poorly only in subjects where the quality of the SLO images was substandard.

Breathing retraining and exercise conditioning in patients with chronic obstructive pulmonary disease (COPD): a physiological approach.
In this review we shall consider the commonest techniques to reduce dyspnea that are being applied to patients with chronic obstructive pulmonary disease (COPD) subjected to a pulmonary rehabilitation program (PRP). Pursed lip breathing (PLB) and diaphragmatic breathing (DB) are breathing retraining strategies employed by COPD patients in order to relieve and control dyspnea. However, the effectiveness of PLB in reducing dyspnoea is controversial. Moreover, DB may be associated with asynchronous and paradoxical breathing movements, reflecting a decrease in the efficiency ofthe diaphragm. Exercise training (EXT) is a mandatory component of PRP.EXT has been shown to improve exercise performances and peripheral muscle strength. Recent studies have focused on the effect of EXT on breathlessness. However, concerns persist as to whether the decreased sensation of dyspnea for a given exercise stimulus is principally due to psychological benefits of rehabilitation or to improved physiological ability to perform exercise. The effect of EXT on breathlessness may be reinforced by inhaling oxygen. However, two studies have recently shown that breathing supplemental oxygen during training has either a marginal effect or no advantage over training. In a comprehensive PRP, strength training (ST) and arm endurance training (AET) could have a role in decreasing peripheral muscle weakness and metabolic and ventilatory requirements for AET. The role of unloading the respiratory muscles during EXT has to be

Comitant strabismus.
This year's review of the literature on comitant strabismus is presented. The main problems in treating strabismus disorders are accurately diagnosing the condition and designing effective treatment plans. A better understanding of the underlying motility disorder facilitates a better treatment outcome. Several of this year's papers address the better detection and identification of comitant strabismus. Some patients with comitant exotropia and esotropia, however, have superimposed incomitant motility patterns such as dissociated vertical deviation. New insights into the possible etiology of dissociated vertical deviation have emerged through use of the sophisticated scleral search coil technique, which permits the discovery of minute motility changes not visible to the clinician's eye. The same technique was used to clarify the traditional clinical experience that convergence insufficiency can improve with convergence exercises.

The use of lumbar spinal stabilization techniques during the performance of abdominal strengthening exercise variations.
AIM: The lumbar spinal stabilization techniques in abdominal hollowing and bracing are known to facilitate the level of activity in the muscles transversus abdominis and obliquus internus (TA/OI). The relative timing of activation and the effect of combination with other tasks are currently unknown. The objective of this study was to determine whether the performance of abdominal hollowing and bracing could promote the voluntary preferential recruitment of TA/OI muscles when performed prior to abdominal strengthening exercise variations. METHODS: The trunk muscles TA/OI, rectus abdominis and obliquus externus were investigated using surface EMG. A pressure transducer under the lumbar spine detected spinal movement. Eighteen male subjects performed a series of 4 abdominal strengthening exercise variations. Pressure cuff and electromyographic onset times were collected and analyzed. RESULTS: TA/OI muscle site was recruited significantly earlier than the upper rectus abdominis site for the hollow with curl exercise. The TA/OI site was also ranked as first activated site in the majority of subjects during exercises where stabilization techniques of hollowing and bracing were used. CONCLUSIONS: Abdominal hollowing was an effective method for selective preferential voluntary recruitment of TA/OI site prior to the performance of the curl type abdominal strengthening exercise variation. The other variations brace with curl and hold and hollow with rotation also tend to recruit TA/OI site first, however the timing was not significantly different.

Neglected posterior dislocation of the elbow. A reconstruction operation.
A new technique for repair of neglected posterior dislocation of the elbow is described, consisting of open reduction with tendon graft stabilisation to create a medial collateral and an intra-articular "cruciate" ligament. This allows flexion-extension exercises to start six days after operation. Eleven cases are reported in which the average range of movement improved from 38 degrees before operation to 105 degrees after a minimum follow-up of two years, with a mean valgus-varus instability of only 13 degrees. One patient had a postoperative infection but all the others were satisfied with the functional result.

A biomechanical analysis of surgeon's gesture in a laparoscopic virtual scenario.
Minimally invasive surgery (MIS) has become very common in recent years thanks to many advantages that patients can get. However, due to the difficulties surgeons encounter to learn and manage this technique, several training methods and metrics have been proposed in order to, respectively, improve surgeon's abilities and assess his/her surgical skills. In this context, this paper presents a biomechanical analysis method of the surgeon's movements, during exercise involving instrument tip positioning and depth perception in a laparoscopic virtual environment. Estimation of some biomechanical parameters enables us to assess the abilities of surgeons and to distinguish an expert surgeon from a novice. A segmentation algorithm has been defined to deeply investigate the surgeon's movements and to divide them into many sub-movements.

Observations on pilot neurosensory control performance during saccadic eye movements.
Saccadic eye movement system performance was investigated to determine whether neurosensory and motor system function is improved by training. There were 2 populations studied--12 Air National Guard pilots, individuals with extensive visual training, and 12 nonpilots. Each subject executed 54 saccadic eye movements while tracking an LED target which moved at random from one location to another. The target display consisted of nine small LED's, each separated by 5 degrees. The ordering of the target movements, as well as the time interval between target movements, were randomized. Horizontal saccadic eye movements were recorded from infrared signals reflected from the anterior surface of the cornea. Signals for bilateral tracking were digitized using an analog-to-digital converter and stored in the hard disk of an IBM/XT. Results using advanced digital processing techniques indicate no significant differences in neurosensory and motor system function during saccadic eye movements between the two populations. A time-optimal central nervous system control mechanism is described which cannot be improved upon by training or exercise.

The calcium-sensitive dye arsenazo III inhibits calcium transport and ATP hydrolysis by the sarcoplasmic reticulum calcium pump.
The calcium-sensitive dye, arsenazo III, was found to interact with sarcoplasmic reticulum vesicles and to inhibit markedly the rate of calcium transport and ATP hydrolysis by these vesicles, thus perturbing the transport process it was meant to monitor. Caution should therefore be exercised when using this dye to monitor calcium movements.

Analogy between training for dancers and problems of adjustment to microgravity: an evaluation of the subjective vertical in dancers.
"Moderne dance" (as opposed to a more academic or classical dance form) uses techniques from kinesiology, anatomy and improvization which are adapted to a cultural, technological and political environment. The function of a choreographic system is to take and give a measure of the world. This includes, with the present tendency of the evolution of culture, a new "naturalism" which seeks the secrets of the body. Dance movements express in terms of space the dimension fo the infinite. It gives somehow the measure of a world within which everything is relative. Except for the speed of light, time and space are bound together by the same principle. The qualities of body awareness and specific motricity in dancers imply--besides a strict discipline--balance, coordination, muscular performance and perfect orientation, problems that astronauts also encounter in microgravity. Could chosen exercises used in modern dance technique be applied to the training of astronauts? Dancer-choreographer Kitsou Dubois has been working in this direction since 1988. She was granted a "Villa Medicis Hors Les Murs" by the French Ministry of Foreign Affairs, to carry on with her research at NASA, Houston, Tex. in April 1989. It allowed her to investigate the reality of this analogy. She intends to evaluate the dancers' subjective vertical refering to Mittelstaedt's observations on the proportional relationship between "space sickness" and some astronauts poor evaluation of the subjective vertical. This study should create a relationship between a choreographer's empirical intuition and a scientific reality.

The dysphagia diagnostic procedure as a treatment efficacy trial.
In all of these case reports, the patient's swallow function and the effect of therapy procedures on this function could be observed and measured from the videofluoroscopic assessment. In some cases, effects could be measured using other imaging procedures. The effects of each swallow therapy procedure can be measured by examining specific physiologic elements of the swallow. Table 3 presents the various therapy procedures and appropriate efficacy measures for each. In some cases, introduction of therapy procedures into the diagnostic evaluation can immediately enable the patient to begin eating. In other cases, evaluation of the effectiveness of the therapy procedure can validate its appropriateness for use with a patient in building the neuromuscular control necessary to return to oral intake. Not all therapy procedures can be introduced into the diagnostic setting, however, since they do not all result in immediate effects. For example, range of motion exercises for the lips, tongue, and/or jaw do not have an immediate effect, but typically show an effect after 2 to 3 wks. However, the clinician can still quantify the effects of range of motion exercises by measuring the patient's structural movement at each therapy session. When a second assessment is completed, change in range of motion of the target structure can be assessed by comparing the first and second studies. Introducing treatment techniques into the diagnostic swallowing assessment requires the clinician to read the results of the radiographic study or other imaging procedure immediately and identify the physiologic dysfunction so that appropriate therapy procedures can be selected and introduced. Because videofluoroscopy involves X-ray exposure to the patient, all possible treatment techniques cannot be attempted while in X-ray. Rather, the clinician must select those techniques believed to be most appropriate for that patient's anatomy and swallow physiology. When effective techniques are identified, the videotape of the diagnostic procedure can be used as an educational tool with the patient and his or her family, nurses, physicians, and others to educate and counsel them regarding the rationale for use of particular procedures with the patient, including introduction of particular posture, diets, etc. This type of visual evidence often improves patient and family compliance with therapy recommendations.
