The purpose of this study was to characterize Cognitive Motor Dual Task (CMDT) costs for a community-based sample of older adults with Motoric Cognitive Risk Syndrome (MCR), as well as investigate associations between CMDT costs and cognitive performance. Twenty-five community-dwelling older adults (ages 60-89 years) with MCR performed single and dual task complex walking scenarios, as well as a computerized cognitive testing battery. Participants with lower CMDT costs had higher scores on composite measures of Working Memory, Processing Speed, and Shifting, as well as an overall cognitive composite measure. In addition, participants with faster single task gait velocity had higher scores on composite measures of Working Memory, Processing Speed, and overall cognition. Taken together, these results suggest that CMDT paradigms can help to elucidate the interplay between cognitive and motor abilities for older adults with MCR.
Functional hand splints have been in use in a number of spinal injury units in the USA since the early 1950s. The splints are designed to provide a pinch-grip either by harnessing wrist dorsiflexion or by external power. Such devices are little used in the United Kingdom. This paper describes the results of late provision of 62 such splints in a Disabled Living Unit. A proportion of tetraplegic patients found such splints of considerable functional value. It is estimated that some 30–60 patients each year would benefit from them if appropriate facilities for early fitting were available.
age, 21.7 ± 6.1; BMI, 25.0 ± 4.3; 50% female) who sustained an ACL tear volunteered for a physical therapy rehabilitation study. At study baseline, 3-day diet records were collected. Participants recorded food and drink intake for two weekdays and one weekend day. A registered dietitian educated participants about keeping food records and sent prompts to complete records on assigned days. Food records were analyzed, and participants completed isokinetic dynamometer assessment including knee extension maximal voluntary isometric contraction (MVIC, Nm/kg) and rate of torque development (Nm*kg -1 *s -1 ) evaluated from contraction initiation to 100 ms (RTD 100 ) and 100 ms to 200 ms (RTD 200 ). The Leg Symmetry Index (LSI) was used to compare the injured limb to the healthy limb to identify diet associations. Bivariate correlations (Pearson) were used to identify associations between LSI and dietary variables (kcal or g/kg). RESULTS: On average, participants consumed 1828 ± 518 kcal (25.2 ± 7.2 kcal/kg kcal), 75.2 ± 26.8g (1.02 ± 0.30 g/kg) of protein, 79.2 ± 28.7 g (1.08 ± 0.37g/kg) fat, and 201.1 ± 67.1 g (2.81 ± 1.06 g/kg) carbohydrate. Both energy (kcal/kg) and carbohydrate (g/kg) intake were positively associated with LSI values for RTD 100 (carbohydrate: R= 0.484, p= 0.012; energy: R= 0.412, p= 0.018) but not RTD 200 or MVIC. Protein and fat intake were not associated with any LSI value (p>0.05). CONCLUSION: Our results show total energy and carbohydrate intake positively associate with strength indices following ACL injury. These findings underscore the importance of nutritional status to support functional recovery following ACL injury and highlight the need to study the role of carbohydrate intake needs during recovery from ACL injury.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
