Peningkatan Kenyamanan Lansia Dengan Nyeri Rheumatoid Arthritis Melalui Model Comfort Food for the Soul

One of the elderly\u27s problems in musculoskeletal system was Rheumatoid Arthritis (RA). In the elderly with RA had a main complaint of pain which can also be a stressor to stress. One form of intervention in the model of comfort food for the soul can be done by religious music therapy. The purpose of this study was to determine the effect of comfort food for the soul model on the stress level and comfort. This study used Quasy experiment with pre-posttest control group design. Total samples were 32 respondents gotten by purposive sampling were divided into experiment and control groups. Dependent variable data were collected by DASS questionnaire (stress level) and GCQ (comfort). Results of stress level data were analized by Wilcoxon Sign Rank Test in each group showed p = 0.001 (experiment) and p = 0.262 (control), and the comfort data p = 0.002 (experiment) and p = 0.180 (control). Mann Whitney Test showed p = 0.000 (stress level) and p = 0.008 (comfort), p <0.05 which means there were significant effect of comfort food for the soul model on stress level and comfort. Religious music therapy could be reduce stress levels of elderly due to soft music will encourage a sense of relaxation. Music into the auditory nervous to the HPA Axis that improved production of β Endhorphin. Advise for nurse in Elderly hostel to apply model of comfort food for the soul by religious music therapy as an alternative therapy to reduce stress and increase comfort

The effects of surface compliance on greyhound galloping dynamics

© IMechE 2019. Greyhounds are the fastest breed of dog and can reach a speed up to 68 km/h. These racing animals sustain unique injuries seldom seen in other breeds of dog. The highest rate of life-threatening injuries in these dogs is hock fracture, mostly of the right hind-leg. One of the main injury contributing factors in this sport is the track surface. There are some studies into the ideal track surface composition for greyhound racing but almost no study has investigated the body–surface interaction. Accordingly, the purpose of this work is to study the effect of surface compliance on the galloping dynamics of greyhounds during the hind-leg single-support phase which is a critical phase in hock injuries. Thus, a three degrees-of-freedom model for the greyhound body and substrate surface is designed using spring-loaded inverted pendulum method. The results showed that forces acting on the hind-leg were substantially affected when the surface compliance altered from the relatively hard (natural grass) to a relatively soft surface (synthetic rubber). The main contribution of this work is designing a mathematical model to predict the dynamics of the hock and the hind-leg as the most vulnerable body parts in greyhounds. Furthermore, this model can be used to optimise the greyhound track surface composition and therefore improve the safety and welfare within the greyhound racing industry

Analysis of agile canine gait characteristics using accelerometry

© 2019 by the authors. Licensee MDPI, Basel, Switzerland. The high rate of severe injuries associated with racing greyhounds poses a significant problem for both animal welfare and the racing industry. Using accelerometry to develop a better understanding of the complex gait of these agile canines may help to eliminate injury contributing factors. This study used a single Inertial Measurement Unit (IMU) equipped with a tri-axial accelerometer to characterise the galloping of thirty-one greyhounds on five different race tracks. The dorsal-ventral and anterior-posterior accelerations were analysed in both the time and frequency domains. The fast Fourier transform (FFT) and Morlet wavelet transform were applied to signals. The time-domain signals were synced with the corresponding high frame rate videos of the race. It is observed that the acceleration peaks in the dorsal-ventral accelerations correspond to the hind-leg strikes which were noted to be fifteen times the greyhound’s weight. The FFT analysis showed that the stride frequencies in all tracks were around 3.5 Hz. The Morlet wavelet analysis also showed a reduction in both the frequency and magnitude of signals, which suggests a speed reduction throughout the race. Also, by detecting abrupt changes along the track, the wavelet analysis highlighted potentially hazardous locations on the track. In conclusion, the methods applied in this research contribute to animal safety and welfare by eliminating the factors leading to injuries through optimising the track design and surface type
