This study aimed to determine the validity and reliability of isometric knee extension muscle strength measurements using a belt-stabilized hand-held dynamometer compared to that using an isokinetic dynamometer with the participant in a sitting posture. [Participants and Methods] Forty-two university students participated. The isometric knee extension muscle strength was measured using a hand-held dynamometer and an isokinetic dynamometer. For both measurements, the participants were in the similar sitting posture. The sitting posture maintained trunk stability, with the hands on the bed, and the non-measurement-side toe touching the floor or table. The intra-class correlation coefficient and the relevance were verified. [Results] Intra-rater correlation coefficient (1, 1) of the two measurements was ≥0.75. A significant difference was found in the measurement value between males and females. No significant difference was found between the measurements value of the two devices. A significant positive correlation was found in the measurement value of two devices in the male participants.[Conclusion] When compared to the standard method of isometric knee extension muscle strength measurements using an isokinetic dynamometer with the participant in the sitting posture, measurements using the belt-stabilized hand-held dynamometer were considered valid and highly reliable in the male participants.

There is no established learning methods for movement procedures for activities of daily living. Patients with higher brain dysfunction and other disorders encounter challenges with movement procedures. Therefore, as a basic study on the memorization methods for movement procedures, we examined the differences between the effects of two memorization methods on healthy participants. [Participants and Methods] Forty student participants were asked to memorize and recall 10 movement elements. The control condition comprised all presented movements; whereas the intervention method comprised two movement elements (one block) each. The number of sets wherein all 10 movements were recalled and the number of consecutive recalls per set after 7 days were compared between the two conditions. [Results] The intervention method engendered significantly fewer sets that were recalled and significantly more consecutive recalls. [Conclusion] It is suggested that the method of presenting the movement procedure in smaller pieces is a more effective memory method than presenting the entire procedure.

To become a physical therapist, one must attend a training school, attend various lectures, and memorize many terms, and this requires efficient memorization. Therefore, we studied the effects of two different methods, in which nonsense words were presented visually, on recall. [Participants and Methods] The participants were 15 university students. They were shown one set of 10 words for 5 minutes. In the control condition, all 10 words were constantly displayed for 5 minutes, and in the intervention condition, one word was erased every 30 seconds. After repeating this procedure with 7 sets, the number of participants who could recall all 10 words, the number of sets in which the participants could recall all 10 words, the number of words correctly answered, and the number of words recalled after 24 hours were compared between the two conditions. [Results] The number of sets in which all words were recalled was significantly lower for the intervention condition, but the number of words recalled was significantly higher. The number of words recalled at 24 hours was significantly higher for the intervention condition. [Conclusion] The results suggest that erasing words one by one is more effective for memorization of visual presentation than displaying all the words all the time.
