Not just when, but how: An exploratory dual-control approach to video feedback in motor learning.
The present study provides exploratory evidence for a novel dual-control paradigm. It examines whether combining temporal over video feedback timing with learner-controlled interactive playback functions (pause, slow-motion, rewind) would enhance motor skill acquisition beyond temporal autonomy alone. Sixty-four novice adults were randomly assigned to one of four conditions: Full Control (self-controlled timing + interactive replay), Partial Control (self-controlled timing + non-interactive replay), Yoked Full Control (externally controlled timing + interactive replay), or Yoked Partial Control (externally controlled timing + non-interactive replay). Motor accuracy (Radial Error), movement consistency (Bivariate Variable Error), technical execution, and self-efficacy were assessed at pre-test, 24-h retention, and 72-h retention following two acquisition sessions on a dart-throwing task (120 trials total). The Full Control group demonstrated the greatest and most durable learning gains across all outcomes. The Group × Time interaction was significant across all dependent variables (η2ₚ ranging from 0.140 to 0.234), with Full Control demonstrating superior retention at both 24 and 72 h relative to other groups (though differences relative to Partial Control were more pronounced at 72-h retention). Critically, the Yoked Full Control group showed comparatively weaker outcomes despite access to the same interactive playback functions. These findings suggest that interactive video tools may be most useful when learners can regulate both when feedback is accessed and how it is inspected. Theoretical and practical implications for the design of learner-centered video feedback systems are discussed.

Feedback of true heart rate during exposure in vivo. Partial replication with methodological improvement.
Ten specific phobics improved during a mean of two sessions of experimental treatment by exposure in vivo in a balanced design. Short-term results replicated those of a previous study that self-control of heart rate with the aid of biofeedback significantly reduced heart rate during treatment, but this did not hasten reduction of subjective anxiety, nor of respiratory rate or skin conductance responses. An hour's pretreatment training in self-control of heart rate with the aid of feedback did not enhance the effect. Mere instructions to lower heart rate without feedback had a significant effect during treatment, but the addition of heart rate feedback to instructions significantly augmented the decline in heart rate.

[Behavior therapy in disorders of dietary behavior].
Behaviour therapies using conditioning principles have been successful in the treatment of some psychopatological eating behaviours. Such have been the cases for anorexia nervosae in adolescents and adults, refusal to eat in the young child and difficulties of swallowing. Some of these cases are described. Research has been done in different countries on the applications of these methods to the treatment of obesity caused by overeating which appears very frequently in our societies. Systematic and covert desensitization and operant conditioning using positive reinforcements are more frequently used in these behaviour modification procedures than aversive methods. More recently, researches on self-control (self-reward and self-punishment) have shown it as a very efficient tool for inducing weight loss. These methods using self-control have been applied to large populations: after a first, careful examination of the patient's eating behaviour, the program of reinforcement is established. It can be partially controlled by written instructions and letters. Results are already encouraging although they need to be followed up. But more research should be done on overeating behaviours, the way they appear and are maintained and on different programs of reinforcement for weight loss.

Approaches to observational study designs and analytical options to evaluate the safety of multi-dose vaccines: a systematic review.
INTRODUCTION: Observational studies require careful considerations when evaluating the safety of multidose vaccines. We reviewed design and analytical approaches in observational studies evaluating the safety of multidose vaccines in the post-licensure phase. METHODS: EMBASE, MEDLINE, Web of Science, and Scopus (2018-2022) were searched for hypothesis-testing studies evaluating the safety of multidose vaccines. Key features from frequently used designs were extracted. RESULTS: Among 123 eligible studies, cohort (46%) and self-controlled case series (SCCS)/self-controlled risk interval (SCRI) (40%) followed by case-control (12%) were the most common designs, and 15% of studies used multiple designs. Among cohort studies evaluating multiple doses, vaccination date (36%) and cohort entry with time-updated exposure status (32%) were frequent approaches used to define time zero. Twenty-eight percent of cohort studies did not report time zero; all but one evaluated COVID-19 vaccine effect on post-delivery and fertility-related outcomes. For SCCS/SCRI, 64% of studies accounted for event-dependent exposures, mainly by including pre-exposure periods (53%) and modified SCCS model (48%), while 20% employed multiple correction strategies. Among studies using multiple designs, 68% reached consistent conclusions. CONCLUSIONS: SCCS/SCRI and cohort designs dominate multidose vaccine safety studies. Clear reporting on time zero in pregnancy and fertility-related cohort studies, and on addressing event-dependent exposures in SCCS/SCRI studies is needed, along with guidance on interpreting results from multiple designs.

Setting generality of blood pressure reductions and the psychological treatment of reactive hypertension.
The setting generality of treatment effects was examined for a client with 3 years' history of essential hypertension. Self-control progressive relaxation training led to durable normotensive blood pressures (BP) in the natural environment and psychology clinic, although medical setting BP remained elevated. Further assessment indicated that this latter problem was a function of conditioned anxiety to medical setting stimuli. Systematic desensitization led to reductions in medical setting BP to normotensive levels, and laboratory psychophysiological assessments confirmed the elimination of the anxiety response. The present case study raises the issue of to what extent such reactive hypertension is a problem for other individuals similarly diagnosed and demonstrates the importance of the assessment of generality of treatment effects for essential hypertension.

Coping with cancer through self-instruction: a hypothesis.
Because most cancer patients seem to cope well with the stresses of their illness, including the psychosocial ramifications, it is important to understand what good copers manage to do, as opposed to those patients who simply defend themselves against persistent problems. This requires making a radical distinction between coping and defending, as well as between healthy adaptive resources and latent pathological dispositions. A case report is presented to illustrate how one "supercoper" solved problems by self-instruction. While cognitive self-instruction may not be applicable for every cancer patient and all problems, it is a working hypothesis deserving of further investigation, since self-control and personal responsibility are essential elements in rehabilitation on all levels. One intervention model for "high distress" cancer patients is outlined.

Mental disturbed violent offenders in Sweden.
Among perpetrators of crimes of violence against persons submitted to psychiatric examination, 16 men with severe mental disorder have been examined by standardized psychologic tests and clinical interviews. Objective anamnestic data have been used to assess social background, individual development and onset of mental disorder. Psychotic as well as nonpsychotic men reacted with violence against threat to the offender's physical existence of his self image. In most instances ego weakness or depleted mental energy exaggerated the feeling of threat or stymied the ability to choose alternative solutions. Abuse of alcohol and narcotics and acute inebriation often weakened self-control and triggered of the act of violence.

Treatment of Raynaud's disease: evaluation of a behavioral approach.
Eight patients with Raynaud's disease were treated with a behavioral program which included skin temperature biofeedback, relaxation training and protocol individualization based on the investigators' psychological understanding of each patient. Three patients improved clinically, although only one learned self-control of skin temperature. Anxiety reduction, brought about by relaxation or changes in the program to suit individual needs, appeared to be an important aspect of the treatment program.

The use of 3-dimensional (3D) printing in teaching musculoskeletal oncology for medical undergraduates.
INTRODUCTION: The approach to integrating relevant anatomy in the medical curriculum has been debated for many years. Current literature has explored the broad impact of 3D printing in medical education. However, there is little evidence on 3D printing for the teaching of musculoskeletal oncology (MSO). This is a self-controlled case series (SCCS) study that aims to analyse the effectiveness of 3D printed models in MSO in enhancing the learning experience, engagement and understanding of clinical and surgical anatomy for medical students. METHOD: A cross-sectional cohort study involving 75 clinical year medical students across 3 years from 2 medical schools that rotated through a single teaching hospital's orthopaedic department. Participants first viewed a set of computed-tomography (CT) images of a large pelvic osteosarcoma from a free open-source database, the Cancer Genome Atlas Sarcoma Collection (TCGA-SARC). A standardised 10-minute pre-intervention questionnaire which comprised 15 questions categorised by: 4 questions in 'anatomical knowledge', 7 questions in 'spatial awareness', 4 questions in 'surgical planning and complications', was administered to assess the baseline knowledge in their interpretation of the pathology via CT images only. Next, a 3D-printed model of the pelvic osteosarcoma, which included colour-coded adjacent structures, was provided as an adjunct to answer the same questionnaire. This concluded with a 5-point Likert scale feedback survey to gauge their perspectives and experience. RESULTS: The mean scores comparing their pre- and post-intervention assessment questionnaire increased by +1.34 from 8.15 (SD = 1.85) to 9.49 (SD = 1.7) (p < 0.001). The final year students had the greatest improvement of +1.54 from 8.00 (SD = 1.89) to 9.54 (SD = 1.59) (p = 0.004). There was no significant difference between the scores amongst the 2 medical schools. 91% of students agreed that the 3D model had helped them further their understanding of the anatomy of the sarcoma and 87% would want 3D printing models to augment their learning in anatomy. Baseline weaker students demonstrated significantly greater improvement in scores compared with baseline stronger students (mean difference +2.04 vs +0.30, p < 0.001). CONCLUSION: 3D printing is an effective teaching adjunct for musculoskeletal oncology surgical anatomy for medical undergraduates and could be used to enhance their understanding and learning experience. 3D models could be integrated in the teaching curriculum of surgical anatomy for undergraduate students.

Effects of intradialytic nutrition on dialysis adequacy and fatigue in hemodialysis patients: a randomized crossover study.
OBJECTIVE: To assess intradialytic nutrition's effects on dialysis adequacy and fatigue in maintenance hemodialysis patients. METHODS: A randomized, two-period, two-sequence, self-controlled crossover trial was conducted in two outpatient hemodialysis centers in Türkiye. Thirty-six patients were randomized; 32 completed both periods. The participants received standardized intradialytic nutrition in one period and no food intake during the control period. Dialysis adequacy was evaluated using the urea reduction ratio and single-pool Kt/V. Intradialytic blood pressure was recorded during dialysis sessions, and fatigue severity was measured using the Piper Fatigue Scale at the end of each period. RESULTS: No significant differences were observed in dialysis adequacy or fatigue scores between the two periods. Intradialytic nutrition was associated with greater reductions in systolic and diastolic blood pressure, particularly during the second hour of dialysis. No clinically relevant adverse events occurred. CONCLUSION: Intradialytic nutrition did not compromise dialysis adequacy or worsen fatigue severity but was associated with increased intradialytic blood pressure reductions. Individualized clinical decisions and careful hemodynamic monitoring are warranted when implementing intradialytic nutritional interventions.

A behavior modification training program for staff working with drug addicts.
This paper described a Behavior Modification Training Program, emphasizing self-control, for staff working with drug addicts. The program, which is primarily geared toward the training of paraprofessionals, takes place in ten 1-1/2 hour sessions and includes an overview of behavior modification as well as instruction in techniques of relaxation, desensitization, self-image improvement, behavior analysis, behavior control, assertive training, rational thinking, and how to set up and run similar behavior modification training programs for staff and patients. Since this training began at the New Jersey Neuropsychiatric Institute in November 1971, a total of 898 staff members, mostly paraprofessionals working with addicts, alcoholics, mentally ill patients, and inmates, including 53 from our own institution, 576 persons from other facilities in New Jersey, and 269 from facilities in other states, have been trained, while 2,021 patients have been trained in similar programs. Most of this training has been accomplished by paraprofessionals. Preliminary evaluation data have been promising and the response of participants enthusiastic.

Data regarding the restorative effects of the partial removal of the liver in advanced stages of toxic cirrhosis.
The effects of subtotal hepatectomy of albino rats liver cirrhois at 6 and 9 months after the start of CCl4 administration were studied. The results were assessed through self-control and comparison with similar groups in which the spontaneous reversibility of cirrhotic lesions was followed. In the group of 6 months, the liver exeresis results in normalization of morphological and biochemical liver aspects within a period of one month from the intervention. In the group of 9 months, one may also note a stimulation of the regenerative capacity of parenchyma and marked collagenolytic effects without the complete restoration of the stroma/parenchyma ratio. It seems that the major exereses are also effective in the advanced stages of liver cirrosis once the threshold of spontaneous reversibility has been exceeded.

Comprehensive rehabilitation of patients having chronic low back pain.
Seventy-two patients having chronic back pain, representative of high-risk demographic and personality populations, received a broad range of therapeutic modalities designed around the theme of self-regulation. The self-regulation principle was used in: (1) biofeedback training for teaching self-regulated muscle relaxation; (2) psychological counseling emphasizing self-control techniques for the management of stress and anxiety, including assertion training; (3) patient-regulated medication program; (4) patient involved case conferences; (5) physical therapy program emphasizing reconditoning; (6) comprehensive vocational rehabilitation services; (7) a series of educational lectures; (8) a therapeutic milieu designed for relaxation, recreation and socialization. Utilizing a success criteria of functional physical activity at discharge (average length of stay, 45 days) and levels of vocational restoration (employable, in training, or employed at 30 days postdischarge), 57 of the patients demonstrated unimpaired physical functioning levels and 59 of the patients were at success levels of vocational restoration.

[Behavioral rehabilitation of nonspecific symptoms occuring after craniocerbral trauma (author's transl)].
The purpose of this study was to develop a behavioral rehabilitation program for patients with long-term nonspecific symptoms following craniocerebral trauma. In 47 patients we analyzed symptoms typical of "illness behavior" (e.g. complaining tendency, depression, irritability, psychosomatic pain, problems in job performance and social interaction) as possible targets for behavior modification. We then developed a behavioral training program to teach the patients various techniques of self-control (relaxation, desensitization, self-image training, analysis and control of illness behavior, assertiveness, performance techniques), our program being based on studies in the U.S.A. using similar approaches. For a preliminary testing two groups of 8 and 6 patients each were treated by different therapists. The patients worked through a section of the program manual prior to each group session. During the sessions proper (a total of 8 weekly two-hour sessions) the different techniques were practiced under the therapist's supervistion. In both groups a significant reduction in illness behavior as indicated on questionnaires and in 3-month follow-up was found. These encouraging results need to be further substantiated by controlled outcome studies.
