Objectives: We aimed to determine the usefulness and effectiveness of a submandibular push exercise with visual feedback from a pressure sensor in patients with dysphagia through continuous exercise sessions. Methods: Twelve patients with dysphagia of various etiologies were included. A total of five exercise sessions (every 3 or 4 days) over three weeks were conducted. During the submandibular push exercise, patients were instructed to maintain a maximum force for 3 s, repeated for 1 min to measure the number of exercises, the maximum pressure, and the area of the pressure-time graph. We statistically compared the values of each exercise trial. Results: Among the 12 patients, eight completed the exercise sessions. As the number of exercise trials increased, the maximum pressure and the area in the pressure-time graph showed a significant increase compared to the previous attempt (p < 0.05). The maximum pressure and the area of the pressure-time graph improved from the first to the fourth session (p < 0.05). The values were maintained after the fourth session, and there was no significant difference between the fourth and the fifth exercise (p > 0.05). There was no significant difference between successful and non-successful groups, except for the Modified Barthel Index (p < 0.05). Conclusion: Through repetitive exercise training, the submandibular push exercise using visual feedback from a pressure sensor can be applied as an exercise method to strengthen swallowing related muscles, such as the suprahyoid and infrahyoid muscles. However, additional studies including more patients and a long-term study period are warranted to evaluate the effects of the exercise for improvement of dysphagia.

Blood Pressures

Venous occlusion by means of a sphygmomanometer cuff is a well-established part of the procedure for assessment of fibrinolytic capacity. It has been suggested that the resultant intravenous pressure is responsible for plasminogen activator release.In this present study we wanted to compare i .v. pressure in the upper and lower limbs, during venous occlusion, and measure t-PA ag release. 8 male volunteers participated. A VenfIon(O.D. 1.2 mm) was inserted in a distal, superficial vein. Blood samples, discarding the first 2-3 ml. were drawn at 4 min. intervals and pressure recordings (Hewlett-Packard)made every min. during the first 8 min. of venous occlusion and thereafter at 4 min. intervals. The cuff was inflated to a pressure midway between systolic and diastolic values after separate measurements of blood pressures of the upper and lower extremities. The occlusion lasted for 20 min.Blood pressure measurements in the lower limbs gave consistently higher values than for the upper limbs. Hence, the resultant cuff pressure was on the average 20 mmHg higher in the legs.There was no significant difference in i.v. pressure, evaluated as total area beneath a pressure/time graph, between the upper and lower extremities. In the arms the i.v. pressure reached a plateau phase after 2-4 min. The pressure buildup was slower in the legs.t-PA values for the upper limbs after 20 min. of venous occlusion: median 15 ng/ml (range 9.4-26.0) and for the lower limbs: 8.15 ng/ml (range 4.8-13.3). This difference is significant, p = 0.035. There was no sifnificant difference between resting t-PA ag' levels prior to occlusion.We conclude that the fibrinolytic response, measured as t-PA ag, after venous occlusion, is twice as high in the upper as in the lower limbs and not 4-times as high as previously claimed. A possible explanation for the lower fibrinolytic response, could be the slower buildup of i.v. pressure during venous occlusion in the lower extremities.

Foot Alignment

Context:Altered foot dynamics due to malalignment of the foot may change plantar-pressure properties, resulting in various kinds of overuse injuries.Objective:To assess the effect of foot characteristics on plantar-pressure-related measures such as maximum pressure, maximum pressure–time, and pressure–time integral underneath the medial aspect of the foot during running.Design:Cross-sectional.Setting:Laboratory. Participants: 8 men and 17 women.Main Outcome Measures:Static non-weight-bearing rear-foot and forefoot alignment and navicular drop were measured. Plantar-pressure data were collected while subjects jogged at 2.6 m/s on a treadmill. Maximum pressure, time to maximum pressure, and pressure–time integral of the medial side of the foot were extracted for data analysis. Multiple-regression analysis was used to examine the effect of arch height and rear-foot and forefoot alignment on maximum pressure and pressure–time integral in the medial side of the foot.Results:In the medial rear-foot and midfoot regions, only rear-foot alignment had a significant effect on the variance of maximum pressure and pressure–time integral. There were no significant difference effects in the medial forefoot region.Conclusion:Rear-foot alignment was found to be a significant predictor of maximum plantar pressure and pressure–time integral in the medial rear-foot and midfoot regions. This indicates that control of rear-foot alignment may help decrease plantar pressure on the medial region of the foot, which may potentially prevent injuries associated with excessive rear-foot eversion.

A tongue pressure unit for measurement of lingual strength and patterns of tongue pressure is described. It consists of a force displacement transducer, a single channel, direct writing recording system, and a specially designed tongue pressure disk, head stabilizer, and pressure unit holder. Calibration with known weights indicated an essentially linear and consistent response. An evaluation of subject reliability in which 17 young adults were tested on two occasions revealed no significant difference in maximum pressure exerted during the two test trials. Suggestions for clinical and research use of the instrumentation are noted.

Introduction Illusion of movement induced by tendon vibration is an effective approach for motor and sensory rehabilitation in case of neurological impairments. The aim of our study was to investigate which modality of visual feedback in Virtual Reality (VR) associated with tendon vibration of the wrist could induce the best illusion of movement. Methods We included 30 healthy participants in the experiment. Tendon vibration inducing illusion of movement (wrist extension, 100Hz) was applied on their wrist during 3 VR visual conditions (10 times each): a moving virtual hand corresponding to the movement that the participants could feel during the tendon vibration (Moving condition), a static virtual hand (Static condition), or no virtual hand at all (Hidden condition). After each trial, the participants had to quantify the intensity of the illusory movement on a Likert scale, the subjective degree of extension of their wrist and afterwards they answered a questionnaire. Results There was a significant difference between the 3 visual feedback conditions concerning the Likert scale ranking and the degree of wrist’s extension (p<0.001). The Moving condition induced a higher intensity of illusion of movement and a higher sensation of wrist’s extension than the Hidden condition (p<0.001 and p<0.001 respectively) than that of the Static condition (p<0.001 and p<0.001 respectively). The Hidden condition also induced a higher intensity of illusion of movement and a higher sensation of wrist’s extension than the Static condition (p<0.01 and p<0.01 respectively). The preferred condition to facilitate movement’s illusion was the Moving condition (63.3%). Conclusions This study demonstrated the importance of carefully selecting a visual feedback to improve the illusion of movement induced by tendon vibration, and the increase of illusion by adding VR visual cues congruent to the illusion of movement. Further work will consist in testing the same hypothesis with stroke patients.

In Kendo, the ability to execute a technique within the shortest time is essential for winning. The purpose of this study was to utilise an in-house developed automatic headgear-scoring sensor with a buzzer to determine the auditory response reaction time (ARRT) of professional (PK) and amateur (AK) Kendo practitioners. ARRT is defined as the time required for a participant to hit a target after a buzzer is sounded. A total of 14 participants took part in this study. The participants were requested to hit the opponent’s headgear target, which consisted of a pressure sensor, upon hearing the buzzer. The average reaction time of PK is 0.44 s, and for AK 0.58 s, with a significant difference between the two groups (p < 0.0001). The in-house developed automatic headgear-scoring sensor with buzzer can be utilised to assist a Kendo practitioner in training to shorten the response reaction time to improve competition performance.

Few studies of ankle arthrodesis have assessed tarsal mobility. This study was performed to evaluate radiographically the effect of ankle arthrodesis on tarsal motion. Thirty patients (31 ankles) returned for clinical and radiographic examination, review of charts, and completion of questionnarie forms. Radiographs were evaluated for success of fusion, position of fusion, tarsal motion, hindfoot position, and subtalar and midtarsal arthritis. The median follow-up time was 7.0 years (range 2–20 years). Results showed that fusion was achieved in 22 patients (71%). The evaluation score based on the grading system of Mazur et al. 16 correlated with success of fusion and patient satisfaction. However, no correlation existed between evaluation score and tarsal motion or position of fusion in the sagittal or coronal planes. Radiographic evaluation showed no significant difference between tarsal motion of the fused side and the unfused side. Tarsal mobility was not affected by ankle arthrodesis or by the techniques performed to achieve fusion.

An abdominal physical examination is one of the most important tools in evaluating patients with acute abdominal pain. We focused on palpation, in which assessment is made according to the patient’s response and force feedback. Since palpation is performed manually by the examiner, the uniformity of force and location is difficult to achieve during examinations. We propose an integrated system to quantify palpation pressure and location. A force sensor continuously collects pressure data, while a camera locates the precise position of contact. The system recorded, displayed average and maximum pressure by creating a pressure/time curve for computer-aided diagnosis. Compared with previous work on pressure sensors of quantifying abdominal palpation, our proposed system is the integrated approach to measure palpation force and track the corresponding position at the same time, for further diagnosis. In addition, we only make use of a sensing device and a general web camera, rather than commercial algometry and infrared cameras used in the previous work. Based on our clinical trials, the statistics of palpation pressure values and the corresponding findings are also reported. We performed abdominal palpation with our system for twenty-three healthy participants, including fourteen males and nine females. We applied two grades of force on the abdomen (light and deep) by four-quadrant and nine-region schemes, record the value of pressure and location. In the four-quadrant scheme, the average pressures of abdominal palpation with light and deep force levels were 0.506(N) and 0.552(N), respectively. In the nine-region scheme, the average pressures were 0.496(N) and 0.577(N), respectively. Two episodes of contact dermal reaction were identified. According to our experiment statistics, there is no significant difference in the force level between the four-quadrant and nine-region scheme. Our results have the potential to be used as a reference guide while designing digital abdominal palpation devices.

The Difference

Background: Bipedal locomotion is a unique feature of human beings and has the advantage of upright mobility. Hence, foot becomes the most important weight loading structure and gets the maximum pressure per unit area. Plantar fasciitis is a painful inflammatory process of the plantar fascia, the connective tissue on the sole of the foot. Thus a study was conducted to determine the effect of strain-counterstrain in plantar fasciitis.Methods: 30 individuals aged between 18-35 years both male and female with plantar fasciitis were recruited for the study. The patients were treated for a period of 7 days using the technique of strain-counterstrain. Pre-intervention and post-intervention scores of Plantar Fasciitis Pain and Disability scale were assessed and were analysed using unpaired t-test and repeated ANOVA.Results: There was equal distribution of occurrence of plantar fasciitis among both the genders out of the population of study.  A significant difference was noted between the pre and post interventional measure of a type of manual therapy called strain-counterstrain (p<0.0001). The difference between pre intervention and after third day intervention did not show much of a difference. However after fifth day a considerable difference was noted (p <0.0001).  It was noted that limited dorsiflexion improved after one week of interventional measure of strain-counterstrain (p <0.0001).Conclusions: The technique of strain-counterstrain which is a type of manual therapy is effective in patients affected by plantar fasciitis. It also showed an improvement in the limited ankle dorsiflexion range.

Background: The Renfrew Unified Treatment for Eating Disorders and Comorbidity (UT) is a transdiagnostic, emotion-focused treatment adapted for use in residential group treatment. This study examined the effect of UT implementation across five years of treatment delivery.Methods: Data were collected by questionnaire at admission, discharge (DC), and 6-month follow-up (6MFU). Patient outcomes were measured by the Eating Disorder Examination-Questionnaire, Center for Epidemiologic Studies-Depression Scale, Brief Experiential Avoidance Questionnaire (BEAQ), Anxiety Sensitivity Index, and Southampton Mindfulness Scale. Data were analyzed for N = 345 patients treated with treatment-as-usual (TAU), and N = 2,763 treated with the UT in subsequent years.Results: Results from multilevel models demonstrated a significant interaction between implementation status (TAU vs. UT) and time, both linear and quadratic, for the depression, experiential avoidance, anxiety sensitivity, and mindfulness variables. Patients treated with the UT showed more improvement in these variables on average, as well as more rebound between DC and 6MFU. Results from multilevel models examining eating disorder outcome showed no significant difference between the TAU and UT for the full sample, but a significant three-way interaction indicated that the UT produced more improvement in the EDE-Q relative to the TAU particularly for patients who entered treatment with high levels of experiential avoidance (BEAQ score).Conclusion: This long-term study of a transdiagnostic, evidence-based treatment in residential care for eating disorders and comorbidity suggests implementation was associated with beneficial effects on depression and emotion function outcomes, as well as eating disorder severity for patients with high levels of baseline emotion regulation problems. These effects did not appear to diminish in the 5 years following initial implementation.
