Abstract Background Quantification of motor performance has a promising role in personalized medicine by diagnosing and monitoring, e.g. neurodegenerative diseases or health problems related to aging. New motion assessment technologies can evolve into patient-centered eHealth applications on a global scale to support personalized healthcare as well as treatment of disease. However, uncertainty remains on the limits of generalizability of such data, which is relevant specifically for preventive or predictive applications, using normative datasets to screen for incipient disease manifestations or indicators of individual risks. Objective This study explored differences between healthy German and Japanese adults in the performance of a short set of six motor tests. Methods Six motor tasks related to gait and balance were recorded with a validated 3D camera system. Twenty-five healthy adults from Chiba, Japan, participated in this study and were matched for age, sex, and BMI to a sample of 25 healthy adults from Berlin, Germany. Recordings used the same technical setup and standard instructions and were supervised by the same experienced operator. Differences in motor performance were analyzed using multiple linear regressions models, adjusted for differences in body stature. Results From 23 presented parameters, five showed group-related differences after adjustment for height and weight (R2 between .19 and .46, p<.05). Japanese adults transitioned faster between sitting and standing and used a smaller range of hand motion. In stepping-in-place, cadence was similar in both groups, but Japanese adults showed higher knee movement amplitudes. Body height was identified as relevant confounder (standardized beta >.5) for performance of short comfortable and maximum speed walks. For results of posturography, regression models did not reveal effects of group or body stature. Conclusions Our results support the existence of a population-specific bias in motor function patterns in young healthy adults. This needs to be considered when motor function is assessed and used for clinical decisions, especially for personalized predictive and preventive medical purposes. The bias affected only the performance of specific items and parameters and is not fully explained by population-specific ethnic differences in body stature. It may be partially explained as cultural bias related to motor habits. Observed effects were small but are expected to be larger in a non-controlled cross-cultural application of motion assessment technologies with relevance for related algorithms that are being developed and used for data processing. In sum, the interpretation of individual data should be related to appropriate population-specific or even better personalized normative values to yield its full potential and avoid misinterpretation.

The purpose of this study was to investigate the relationship between motor performance in the aquatic setting as measured by the Aquatic Independence Measure (AIM) to motor performance on land as measured by the Gross Motor Function Measure (GMFM) and the Pediatric Evaluation of Disability Inventory (PEDI). Fourty- nine children with neuro-motor impairments ages 3 to 7 participated in the study. Pearson correlations were applied to determine the relationships between the AIM and the GMFM, PEDI, and Gross Motor Function Classification System (GMFCS). Significant correlations were found between the total AIM and GMFM scores (r = 69, p < .01) and PEDI self-care sub-scale (r = .79, p < .01) as well as the PEDI mobility sub-scale scores (r = .35, p < .05). The water adjustment sub-scale as measured by the AIM showed the strongest relationship to motor performance on land as measured by the GMFM and PEDI in our sample of 49 children.

Physical Therapy Intervention

EAST syndrome is autosomal recessive disorder due to mutations in gene KCNJ10, a gene encoding a potassium channel expressed in the brain, eye, ear and kidney. It is characterized by four cardinal features; Epilepsy, Ataxia, Sensorineural deafness, and renal salt-wasting Tubulopathy, thus the acronym EAST syndrome. It was rst described as a distinct clinical entity in 2009 by Bockenhauer and scholl, who named this condition EAST syndrome and SeSAME syndrome for Seizures, Sensorineural deafness, Ataxia, Mental retardation and Electrolyte imbalance respectively. Neurodevelopmental delay is evident in most patients with EAST syndrome that were old enough to be assessed; Thus, physiotherapy intervention also plays a vital role in EAST syndrome along with medical management. From physiotherapy perspective; symptomatic management to Improve overall health, wellbeing and motor control becomes ultimate goal in the patient with EAST syndrome. As there is no specic physical therapy treatment approach and no specic tool to evaluate function for children with EAST syndrome; for clinically presented delay development and ataxia, Neurodevelopment therapy (NDT) was utilized as treatment approach and Gross motor function measure (GMFM) & Gross motor performance measure (GMPM) were utilized for assessment in this case study to track progress on follow ups. Result showed marked improvement in GMFM and GMPM scores at follow ups and concluded that Physical therapy intervention improves the gross motor function as well as gross motor performance in patient with EAST syndrome.

The cerebellum is crucial for planning, executing, terminating, and learning movements. The cerebellum compares actual with intended motor performance and optimizes the timing of motor function. Thus, it is important in the adaptation of movement and posture. In addition, the cerebellum contributes to cognition and behavior. The primary fissure divides the cerebellum anatomically into anterior and posterior lobes. The posterior lobe is divided from the flocculonodular lobe by the posterolateral fissure. The cerebellum may also be divided into functional zones, including the vermis (midline), paravermal region, and hemispheres (most lateral).

AbstractThe guideline for therapy should be the improvement of the individual's functionality, not the acquisition of the ill-defined “goldstandard” of normal movement. However, Latash & Anson's suggestion that only primary causes of dysfunction should be treated is problematic for two reasons: First, the distinction between genuine and adaptive changes in motor performance is not always possible, and second, adaptive changes do not necessarily improve motor function, but may actually be detrimental to the system's performance.

BACKGROUND: Impaired motor control, balance, muscle strength, and respiratory function may affect the exercise capacity related to motor performance and activities in individuals with stroke. OBJECTIVE: To identify a physical parameter that the exercise capacity has the most significant relationship among physical parameters related to motor function, trunk control, balance, and motor performance and activities in individuals with ischemic stroke. METHODS: In total, 241 ischemic stroke patients were recruited in this retrospective study. The clinical measurements included the 6-minute walk test (6 MWT), Montreal cognitive assessment (MoCA), Fugl-Meyer assessment-lower extremity motor function (FMA-LE), trunk impairment scale (TIS), Berg balance scale (BBS), timed up and go test (TUG), 10-meter walk test (10 MWT), functional ambulation category (FAC), and functional independence measure (FIM). RESULTS: The 6 MWT was significantly correlated with the FMA-LE, BBS, TUG, 10 MWT, FAC, and FIM, indicating negative or positive moderate correlations. Additionally, the FMA-LE, TIS, BBS, TUG, 10 MWT, FAC, and FIM, excluding the 6 MWT, showed moderate to strong correlations with all of the other outcome measures, whereas the MoCA showed significant correlations only with the BBS and FIM. CONCLUSIONS: In this study, the exercise capacity has the most significant relationship with the TUG parameter in stroke patients. Additionally, we suggest that significant relationships between 6 MWT and other comprehensive physical functions measurements are closely related to walking ability in individuals with stroke.
