[Purpose] To identify the lumbar loading movements necessary in clinical practice. [Participants and Methods] A questionnaire survey was conducted among physical and occupational therapists in Japan. There were no exclusion criteria regarding the number of years of experience, age, or field of employment. The participants were randomly selected and administered the questionnaire. They were asked to list and rank the lumbar loadings they considered necessary. [Results] A total of 739 respondents participated in the survey. The results of this nationwide survey indicated that the lifting movement of heavy objects in the trunk flexion position was the most common movement (for 354 participants). [Conclusion] The main loading movements of the lumbar spine were reported to be heavy lifting movements (in the trunk flexion position) and trunk rotation movements. As perspectives, we aim to conduct an analytical study of some of lumbar spine loading movements outlined in this study, using a musculoskeletal simulator and electromyography.

Supporting the elderly by utilizing their remaining functions will lead to the extension of their healthy life span. In this study, we developed a portable cane-type standing and sitting positional mobility support device. In this study, we developed a cane-type mobility support device, and selected a suitable support direction for elderly people by dynamic analysis simulation. In addition, the necessary assisting force for the elderly was examined and the assisting force was set. The effectiveness of the device was evaluated by measuring the surface electromyogram of healthy subjects. As a result, it was found that the specifications of this device were effective when the assist direction was 30 degrees and the assist force was 110 N. From the measurement of the surface electromyogram, it was found that the device was effective for both standing and sitting motions. It also helps to ensure the safety of the sitting motion of elderly people.

Effect of knee orthosis on joint position sense in patients with osteoarthritis of the knee -Analysis focusing on the wearing pressure of the orthosis- Reviewed

In patients with knee osteoarthritis, wearing a knee orthosis improves joint positioning. However, no attention has been paid to the wearing pressure, which indicates the tightness of the hook and loop fastener. The neurophysiological effects of local compression have been obtained by wearing the device. Therefore, increasing the wearing pressure may further improve the sense of joint positioning. In this study, we focused on the wearing pressure of the knee orthosis and examined its effect on joint position perception. The results showed that High Pressure was significantly lower in 60°of knee joint flexion than in Control (p<0.05). It was suggested that increasing the wearing pressure of the flexible knee orthosis may improve the sense of joint positioning.

Identification of the cause of fall during the pre-impact fall period Reviewed International journal

Sasaki Sho, Yamamoto Hiroaki, Kitagawa Kodai, Wada Chikamune

Journal of Physical Therapy Science ( The Society of Physical Therapy Science ) 34 ( 4 ) 320 - 326 2022.04

[Purpose] This study aimed to develop and validate a method for identifying factors that may cause a fall during the pre-impact fall period using wearable sensors. [Participants and Methods] The participants were 23 young people from the public data set (mean age, 23.4 years). Acceleration and angular velocity information obtained from sensors attached to the participant’s waist was used to generate the pre-impact fall. The cause of the fall (slip, trip, fainting, get up, sit down) was then classified with and without the addition of activity of daily living data using three different support vector machine. In addition, we investigated the influence of lead time (0–2.0s) on accuracy. [Results] The quadratic and cubic support vector machine identified the activity of daily living and fall patterns more accurately than the linear support vector machine, and the cubic support vector machine was better for classification, although the difference was slight. The greatest accuracy for predicting the cause of the fall (87.9%) was obtained when the cubic support vector machine was used, activity of daily living was factored into the analysis, and the lead time was 0.25 sec. [Conclusion] Support vector machine can identify the cause of the fall during the pre-impact fall period. Appropriate individualized interventions may be designed based on the most likely cause of fall as identified by this analysis method.
