This paper deals with a Capstone Design project which is a wearable haptic wrist massage device design carried out within the 'Designeer' education program. Following design thinking process is recommended throughout a year in order to ensure a desirable, feasible and viable product. Dealing with a real problem of the field requires open-minded and flexible attitudes both from students and professors. Integrating design in an engineering project does not mean always making better looking product. User experience design allows wider opportunity to engineers to deal with design. A case study of developing a wearable wrist massage device shown in this paper demonstrate haptic design and how haptic properties can be optimized to offer best user experience of hand massaging. This study identified that starting lateral pressure movements from the center in larger area using air tubes gives better feeling as self-massage using wrist wearing devices.

Thoracic outlet syndrome's chief symptom has numbness and tingling sensation of tharm, hand and fingers. In the morning, patient complain of pins and needles of the hands and weakness. TOS classified three categories : Anterior scalene syndrome, Claviculocostal syndrome, Pectoralis minor syndrome Physical therapy of the TOS is heat, massage for soft tissue, stretching exercise for scalene muscles and pectoralis minor muscles, and strengthening exercise for upper trapezius and levator scapular and neck muscles. A main problem of soft tissue is mechanical causes, so physical therapists have to solve that problem by mechanical manual methods.

At the early stages of engineering design, a number of design concepts may be suggested. With a great degree of freedom, making a good choice may be a challenge at this stage. In this study, a simplified evaluation criterion for design concepts is presented based on cost, simplicity and safety. Cost is estimated by the amount of materials and the required level of tolerance. Simplicity is represented by the number of parts, assembly steps, and fasteners. Safety is assessed by the level of potential failure. The proposed criterion is applied to an example design of driving mechanisms for cervical vertebrae massage machine.

The sciatic nerve is the largest nerve among the peripheral nerves, and the damage to the sciatic nerve is caused by mechanical and physical pressure. This is an important disease that consumes a lot of time and money in the treatment process. Among them, research on relieving nerve pain caused by damage to the peripheral sciatic nerve has been made efforts to prevent and treat this disease through various methods such as drugs, natural products, electrical stimulation, exercise therapy, and massage. Existing treatments are not very effective in neurological pain, and countermeasures are needed. Forsythia Fructus, used in this study, has been used as a therapeutic agent for infectious diseases and a pain reliever for cancer from the past, and in past studies, it has been known to properly control the inflammatory response. In this study, rengyolone, a physiologically active substance of Forsythiae Fructus, was administered to rats that caused chronic left nerve pain to verify the pain relief effect. As a result of the experiment, it was found that mechanical pain and cold stimulation pain were significantly reduced in the rengyolone-treated group compared to the non-administered group. In addition, it was found that nerve growth factor (NGF) mRNA expression was significantly reduced and Cyclin-dependent kinase 2 (Cdc2) expression was increased in the rengyolone administration group. This increase in NGF expression is thought to be related to rengyolone's anti-inflammatory regulatory mechanism. It is expected that the reduced NGF was directly involved in pain relief.

The purpose of this study was to confirm the reduction of pain and symptom relief of Parkinson's disease by vertically stimulating the spine through the application of a mechanical bed capable of thermal and massage stimulation. For this purpose, after confirming the segmental motion of the spine due to the use of a medical combination stimulation bed for Parkinson's disease patients, VAS, ODI, gait ability, and spiral drawing tests were performed, and the relationship between the variables was identified. In the 10-day visual analog scale and evaluation of low back pain dysfunction, the average trend of decreasing after bed use was confirmed. For walking ability, a decrease in the moving time and an increase in the moving distance were observed. In the spiral drawing test, the mean test time after using bed was significantly lower than before. As a result, it suggested the possibility of using it as an auxiliary method for recovery and pain relief of Parkinson's disease patients due to spinal segmental movement with mechanical heating and massage. However, this study is a preliminary study, and there is a small number of subjects, so additional research is needed that considers the number and condition of future subjects in detail.

Purpose: To investigate the effects of hyperbaric oxygen therapy (HBOT) on chronic low back pain in elderly patients with impaired functioning in daily life. Methods: 35 subjects with chronic low back pain were randomly allocated into two groups, HBOT group and Placebo group. We applied TENS and mechanical massage to the lower back in both groups. Then 35% oxygen at 1.4 ATA was given to the HBOT group and atmospheric oxygen at 1 ATA to the placebo group. Results: Comparing the HBOT group with the placebo group after performing interventions six times in 2 weeks, a statistically significant difference in the Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI) scores was observed between the two groups. There was a statistically significant difference in VAS and ODI scores (56% and 34.97% respectively) between the HBOT group and the placebo group. A statistically significant difference was ascertained in the degree of variables VAS and ODI in the HBOT group. Conclusion: Application of HBOT in chronic low back pain could be beneficial for reducing pain and could help in functional recovery.

The authors of this study have developed a robot milking system composed of a multi-articular manipulator, a teat-cup attachment system, and an image processing system. In order to verify the efficacy of this system, we have conducted a performance analysis and measurement experiment of milk yield, using dairy cattle. It was concluded that teat recognition using the image processing system, teat-cup attachment, and detachment system did not binder milking. The milking yield of the robot milking system was analyzed based on a lactation curve. As a result, it was determined that the use of a robot milking system had no significant effects on milking yields. The robot milking system described in this study is designed specifically with a focus on teat-cup attachment and detachment performance, as well as the effect of these factors on milking yield. In the future, in-depth studies regarding the washing of the teats prior to milking, teat massage, pre-treatment and post-treatment processes after milking, and disinfection processes shall be conducted, in order to render this system feasible for use in an actual milking parlor.

Hydrogymnastics so that sufficient exercise effect can be obtained using the resistance of water has a positive effect on patients who have to receive arthritis or rehabilitation treatment. However, the studies on the effect are insufficient, and the main cause of their effects has not been unclear yet. In this study, in order to identify the main cause of the effects of Hydrogymnastics, conducted Unsteady fluid flow simulation under the same conditions as the actual environment. The analysis model based on real hands, and the pressure fluctuation applied to the knuckle was analyzed by the computational fluid method. During the underwater movement of the hands, Various sizes of vortices were generated between fingers due to skin surface velocity and flow resistance. Pressure of about -500 Pa to +500 Pa is applied by the vortex flow. Also It was confirmed that the positive pressure and the negative pressure were continuously repeated up to maximum + 2000 Pa at the minimum of -2000 Pa at the portion where the direction was changed. Pressure fluctuations with a frequency of 20 Hz to 70 Hz were added continuously for each knuckle. These continuous pressure fluctuations provide a direct massage effect on the knuckles, an It is judged that the blood circulation at the relevant part is positively affected.
