ABSTRACT
Soccer is the most popular sport worldwide, with over 265 million participants. Soccer is unique in that the ball can be directed deliberately and purposefully with the head, an act referred to as ‘heading’. In recent years, there has been concern about the association between repetitive subconcussive head impacts associated with heading and chronic traumatic encephalopathy. Heading causes immediate changes in biochemical and electrophysiological markers of traumatic brain injury, and some studies have reported brain structural changes and dysfunction in former soccer players. In 2019, it was reported that the mortality associated with neurodegenerative diseases was about 3.5 times higher among former professional soccer players. Following that, in early 2020, the guidance have been published to limit heading by age in some regions including England and Scotland. In this review, we will expound the immediate and long-term effects of heading associated with chronic traumatic encephalopathy and the measures that should be taken into consideration in the practice of soccer instruction, based on the latest findings.
ABSTRACT
This study aimed to clarify the resources required to relieve distress during palliative care delivery to cancer patients. Between April 2015 and March 2017, 1479 outpatients receiving chemotherapy for cancer were screened using the Japanese version of the Support Team Assessment Schedule (STAS-J). When the STAS-J result was 2 points and higher, the patient was considered positive for distress. A certified nurse or pharmacist performed STAS-J screening and, in cases where the patient exhibited distress, took steps to alleviate the problem themselves or consulted another resource. Distress was identified in 181 (12.2%) of the 1479 patients. These 181 patients needed 288 resources. The resources used to alleviate distress were categorized as follows: direct support by certified nurse or pharmacist (153), consultation with the attending physician (98) and other (37). The required resource included the following twelve professionals: attending physician, ophthalmologist, dermatologist, dentist, orthopedic surgeon, palliative care physician, certified nurse, certified pharmacist, medical social worker, clinical psychologist, volunteers for cancer patients, and palliative care team. The frequency of the intervention by the certified nurse or pharmacist (61, 39.9%) in directly alleviating psychiatric distress was significantly higher than by consultation with the attending physician (10, 10.2%) (p<0.0001). However, the frequency of consultation with the attending physician in alleviating physical distress (88, 89.8%) was significantly higher than that of the certified nurse or pharmacist (92, 60.1%) (p<0.0001). We conclude that the certified nurse or pharmacist is important for the delivery of palliative cancer care, because they can directly provide relief from psychiatric distress.
ABSTRACT
Taping is widely used in sports medicine to prevent injury, protect affected sites post injury and relieve pain. However, it is not clear whether taping affects the perception of noxious stimulation because in previous studies, it was difficult to selectively activate Aδ fibers. A recently developed, useful, new tool named intra-epidermal electrical stimulation (IES) can preferentially activate Aδ fibers. We aimed to clarify the effect of taping on pain-related somatosensory evoked potentials (pSEPs) using IES. We recorded pSEPs following IES of the right medial forearm in twelve healthy volunteers. pSEPs were recorded from 9 electrodes on the scalp under control, elastic-taping and white-taping conditions. Under the control condition, subjects relaxed on a comfortable reclining seat without taping, whereas under the taping conditions, they were subjected to taping along the forearm with tension (elastic-taping) and without tension (white-taping). Subjects were asked to assign a visual analog scale (VAS) score after each session. The peak amplitudes of N2-P2 were significantly lower under the elastic-taping and white-taping conditions than those under the control condition. VAS was significantly lower elastic-taping condition than those under the control and white-taping conditions. Moreover, there was a significant positive correlation between the amplitude of N2-P2 and VAS. We revealed that taping along the forearm decreased pSEPs and subjective pain perception under the white-taping and elastic-taping conditions. The underlying mechanism of pain relief was the distraction effect in both taping conditions. In addition, elastic-taping with tension changes afferent inputs mainly from the skin, and this might more effectively decrease the subjective pain perception than that achieved under the white-taping condition.
ABSTRACT
Objectives : Muscle imbalance poses a problem for adequate motor function in patients with cerebral palsy. The adductor and flexor muscles around the hip become dominant, leading to a high risk of hip dislocation. When left untreated, flexion and adduction contracture progresses, leading to various impairments ; hence, it is important to undertake preventive measures at an early stage. Selective muscle release is one form of surgical treatment that has been proven effective, but there is no consensus on the timing of the surgery. Here, we investigated the difference in outcome after muscle release surgery with respect to age. Subjects and methods : The subjects were 26 patients (52 hips) from our medical center who underwent muscle release (partial modification of Matsuo's method) around the hip and were followed up for at least 6 months. Abduction was retained postoperatively by using a cast or prosthetic device. Migration percentage (MP) was measured by simple hip radiography image, and the rates of improvement (preoperative MP . final MP during observation/preoperative MP ×100%) were compared. Results : Higher rates of improvement were observed among patients aged 5 years or less at the time of surgery than those among patients aged 6 years or more. Conclusion : We consider that surgery performed at the age of 5 years or less could lead to favorable results.
ABSTRACT
Taping is widely used by sports trainers to prevent injury and to protect affected sites post-injury. However, it is not clear whether taping affect the perception of somatosensory stimulation. We sought to clarify the effect of taping on somatosensory stimulation using somatosensory evoked potentials (SEPs). We recorded SEPs following transcutaneous electrical stimulation of the right medial forearm in ten healthy volunteers. SEPs were recorded from 9 electrodes on the scalp under control, elastic-taping and white-taping conditions. Subjects relaxed on a comfortable reclining seat without taping in the control condition, while they were subjected to taping along the muscle of forearm with tension (elastic-taping) and without tension (white-taping) in the taping conditions. Results showed that the peak amplitude of N140 did not differ significantly among the three conditions but the peak amplitude of P250 was significantly lower in the elastic-taping condition than control and white-taping conditions. Elastic-taping with tension along the muscles changes various afferent inputs from muscle spindle or skin, and this may affect the perception of somatosensory stimulation.
ABSTRACT
The purpose of this study was to evaluate the effectiveness of water exercise, including functional mobility in water, performed either once or twice a week in elderly who require nursing care. Twenty-one subjects were assigned to two groups. Ten subjects trained once a week for 6 months. Eleven subjects trained twice a week for 6 months. Water exercise consisted of warming up on land and walking,ADL exercise,resistance training, stretching and relaxation in water. Functional mobility was evaluated by FIM during pre-exercise,after 3 months and 6 months. There were significant improvements in functional mobility after 6 months compared to pre-exercise in both groups. Functional mobility in the group who trained once a week did not improve at 3 months compared to pre-exercise. Although the group who trained twice a week showed a dramatic improvement in functional mobility after 3 months compared to pre-exercise, and no change after 3 months compared to after 6 months. These results indicate that water exercise once or twice a week for 6 months, including functional mobility in elderly who require nursing care, can improve functional mobility, especially, exercise twice a week could improve it within 3 months.
