Reliability of ultrasound to measure the distance between lumbar interspinous processes.

Objectives: This study aimed to determine the reliability of ultrasound to measure the distance between interspinous processes of the lumbar spine at the segmental level (i.e., L1-L2, L2-L3, L3-L4, and L4-L5).

Effectiveness of using an unskilled model in action observation combined with motor imagery training for early motor learning in elderly people: a preliminary study.

Aim Of The Study: To investigate a more available model for the early phase of motor learning after action observation combined with motor imagery training in elderly people. To address the purpose, we focused on a slow, unskilled model demonstrating an occasional error.

Materials And Methods: A total of 36 elderly people participated in the current study and were assigned to either the unskilled or skilled model observation groups (n = 12, respectively), or the control group (n = 12).

Absolute and relative reliability of lumbar interspinous process ultrasound imaging measurements.

[Purpose] The intra- and inter-examiner reliabilities of lumbar interspinous process distances measured by ultrasound imaging were examined. [Subjects and Methods] The subjects were 10 males who had no history of orthopedic diseases or dysfunctions. Ten lumbar interspinous images from 360 images captured from 10 subjects were selected.

Validity and reliability of isometric muscle strength measurements of hip abduction and abduction with external hip rotation in a bent-hip position using a handheld dynamometer with a belt.

[Purpose] This study aimed to investigate the relatedness, reliability, and validity of isometric muscle strength measurements of hip abduction and abduction with an external hip rotation in a bent-hip position using a handheld dynamometer with a belt. [Subjects and Methods] Twenty healthy young adults, with a mean age of 21.5 ± 0.

An effective model for observational learning to improve novel motor performance.

[Purpose] To investigate whether for observational learning involving a ball rotation task, an unskilled model showing clumsy finger movements is more effective than a skilled model‏. [Subjects and Methods] Thirty-six young adults were randomly assigned to one of three groups. The unskilled model observation group observed a video of a ball rotation task practiced by a person for a short time.

Reliability and validity of an ultrasound-based imaging method for measuring interspinous process distance in the lumbar spine using two different index points.

[Purpose] This study assessed the reliability and validity of an ultrasound-based imaging method for measuring the interspinous process distance in the lumbar spine using two different index points. [Subjects and Methods] Ten healthy males were recruited. Five physical therapy students participated in this study as examiners.
