Multi-object tracking (MOT) has been notoriously difficult to evaluate. Previous metrics overemphasize the importance of either detection or association. To address this, we present a novel MOT evaluation metric, higher order tracking accuracy (HOTA), which explicitly balances the effect of performing accurate detection, association and localization into a single unified metric for comparing trackers. HOTA decomposes into a family of sub-metrics which are able to evaluate each of five basic error types separately, which enables clear analysis of tracking performance. We evaluate the effectiveness of HOTA on the MOTChallenge benchmark, and show that it is able to capture important aspects of MOT performance not previously taken into account by established metrics.

The purpose of this study was to report that a physical therapist qualified for swimming instruction can provide swimming instruction to children with spastic paraplegia due to cerebral palsy. We examined the role of the physical therapist in the support. Two elementary school children with cerebral palsy participated in this study. The swimming program consisting of 6 sessions was performed over 6 months in an indoor swimming pool. Each session lasted for 30 minutes and was instructed by a trained physical therapist. The 5 categories for evaluation were motor function, muscle tone, activities of daily living, swimming skill, and satisfaction level. Case A showed improvement in streamline floating distance and 15-m time. Case B could not swim 15 m in the first session but completed 15 m within 102 s in the last session. The 3 other categories besides swimming skills did not improve. With a skilled physical therapist’s instruction, children with cerebral palsy may improve their swimming skills over a limited number of sessions without any adverse events. In stroke rehabilitation, gait assessment measures the maximal walking speed and six-minute walking distance, both of which have not been thoroughly investigated as determinants of walking ability. Here, we assessed the methods for evaluating these gait parameters using clinical data on hybrid assistive limb treatment compared with conventional training. In total, 20 stroke patients (hybrid assistive limb group, n=9; conventional group, n=11) participated in this randomized controlled trial. For 12 sessions (three times per week in 4 weeks), the hybrid assistive limb and conventional groups performed gait treatment with hybrid assistive limb and conventional gait training, respectively. Short physical performance battery and walking ability (maximal walking speed and six-minute walking distance) were evaluated pre- and post-intervention. Subsequently, the patients were divided further into two groups low- and high-balance score groups. Maximum walking speed and six-minute walking distance were significantly associated, with a positive relationship observed post-intervention. The high-balance score group showed a significant improvement in the six-minute walking distance compared to the low-balance score group. However, no significant improvement in maximum walking speed was observed between both groups. Due to its sensitivity in detecting differences in balance, six-minute walking distance may be a useful assessment parameter for stroke rehabilitation, particularly in the recovery of physiological walking ability. The movement trajectory in daily motion is strongly associated with information regarding the properties of the environment. In the case of the back-to-sit task, it may vary according to chair property. The purpose of this study was to investigate whether trajectory formation in back-to-sit tasks by healthy adults depends on seat width information. Ten healthy young males performed a back-to-sit task in 5 seat width conditions (80%, 90%, 100%, 110%, and 120% of each participant’s buttock breadth). The motion analysis system and force plates were set at a sampling frequency of 250 Hz. The spatial and temporal variables were calculated to examine the effect of seat width. A questionnaire was also administered to examine whether the participants were aware of each seat width in comparison with their own buttock breadth as narrow or large. The questionnaire results showed that many participants were aware but some were unaware of the relative comparison of their size to the seat width. Nevertheless, the spatial and temporal variables were invariant under the different seat width conditions. In healthy adults, the trajectory formation in back-to-sit tasks is not dependent on the perception of seat width information under their variability as per daily situations. The purpose of this study was to verify the effects of a 3-month multicomponent home-based rehabilitation program developed on the basis of the reevaluation of older people with restricted life-space mobility. The participants were residents in Japan aged ≥65 years who had Life-Space Assessment scores ≤52.3. Multicomponent home-based rehabilitation was conducted by physical and occupational therapists. Each visit included 40-60 min of combined exercise, practicing activities of daily living, improving the home environment, and caregiver support. The programs were developed in accordance with a flow diagram. The primary outcome was life-space mobility evaluated using the Life-Space Assessment score. Overall, 30 participants completed the intervention. The mean age of the participants was 82.4 ± 7.5 years. Three months after the intervention initiation, the Life-Space Assessment scores significantly improved from 12.0 to 30.5. The proportion of participants at maximal life-space level 5 (unlimited mobility) doubled from 16.7% at baseline to 33.3%. The functional independent measure score, fall efficacy scale score, and lower limb strength associated with standing up also significantly improved. We found no significant changes in the geriatric depression scale 5 and self-rated good health scores. Multicomponent home-based rehabilitation can improve life-space mobility in older people with restricted life-space mobility.
