Increased hip adductor activation during sit-to-stand improves muscle activation timing and rising-up mechanics in individuals with hemiparesis.

Long sit-to-stand (STS) time has been identified as a feature of impaired functional mobility. The changes in biomechanics of STS performance with simultaneous hip adductor contraction have not been studied, which may limit indications for use of hip adductor activation during STS training. Ten individuals with hemiplegia (mean age 61.

Relationship Between Shoulder Pain and Joint Reaction Forces and Muscle Moments During 2 Speeds of Wheelchair Propulsion.

The purpose of this study was to determine shoulder joint reaction forces and muscle moments during 2 speeds (1.3 and 2.2 m/s) of wheelchair propulsion and to investigate the relationship between joints reaction forces, muscle moments, and shoulder pain.

Immediate video feedback on ramp, wheelie, and curb wheelchair skill training for persons with spinal cord injury.

We hypothesized that the effects of immediate video feedback (IVF) on training ramp, wheelie, and curb wheelchair skills for persons with spinal cord injury (SCI) would be equivalent to or better than the traditional wheelchair skill training. Participants were manual wheelchair users with recent SCI (thoracic 1-lumbar 1) who were matched (9 pairs) on motor function level, age, and sex and randomly assigned to a control group (conventional training) or an experimental group (IVF training). Participants learned three wheelchair skills and then went through the wheelchair skill competency test, retention test, and transfer test.

Primary cN0 lip squamous cell carcinoma and elective neck dissection: Systematic review and meta-analysis.

Background: Management of clinically negative lymph nodes (cN0) in primary lip squamous cell carcinoma (SCC) has always been a controversial topic.

Methods: A systematic review of English-language electronic databases using Medline, Embase, Cochrane library, Google Scholar, SCI, and specific journals on the subject matter was done. Only the studies mentioning primary nonmetastatic lip SCC with cN0 neck treated by surgery only and having at least 2 years of follow-up data were selected.

An instrumented wheel system for measuring 3-D pushrim kinetics during racing wheelchair propulsion.

The purpose of this study was to design and validate an instrumented wheel system (IWS) that can measure 3-dimensional (3-D) pushrim forces during racing wheelchair propulsion. Linearity, precision, and percent error were determined for both static and dynamic conditions. For the static condition, the IWS demonstrated a high linearity (0.

Fundamental locomotive activity time efficiency with differently positioning drive-axis wheelchairs among elders.

This study examined time efficiency in wheelchair locomotive activities among four different wheelchairs propelled by elders with arms and/or legs. Sixteen elder manual wheelchair users propelled her/his own wheelchair and three wheelchairs (the main drive-axis wheels positioning in front, middle, and rear, respectively) in the test of seven wheelchair locomotive activities of daily living. A Mixed-Model ANOVA and Bonferroni post hoc test (p < .

Effects of Tai Chi exercise on physical and mental health of college students.

The purpose of this pilot study is to examine the effects of Tai Chi Quan, a body-mind harmony exercise, on college students' perceptions of their physical and mental health. A three-month intervention of Tai Chi exercise was administered to college students, and multidimensional physical (PHD) and mental (MHD) health scores were assessed using the SF-36v2 health survey questionnaire before and after the intervention. Thirty college students participated in a 1-hour-long Tai Chi exercise intervention twice a week for 3 months.
