Background
Intervention for older patients with cardiac disease and subthreshold depression (StD) may be an effective strategy to prevent the development of major depressive disorder. The subliminal priming with supraliminal reward stimulation (SPSRS) website developed by us is an advanced intervention that can improve depressive symptoms in individuals with StD by presenting positive word stimuli in videos. However, its efficacy for treating depressive symptoms in older patients with cardiac disease and StD has not been investigated. Here, we present a pilot randomized controlled trial protocol to investigate the preliminary efficacy of an intervention for older patients with cardiac disease with StD.
Methods
The study was designed as a single-center, open-label, pilot, randomized, parallel-group trial. The participants will include 30 older patients with cardiac disease and StD who are hospitalized in acute wards. The Experimental group received the SPSRS intervention (video viewing with positive word stimuli; n = 15) and the Control group will receive the YouTube intervention (video viewing without positive word stimuli; n = 15). In both groups, the intervention will be administered for 10 min per day, five times per week for 1 week. The primary outcome will be the change in the scores on the Japanese version of the Beck Depression Inventory-II at 1 week after the baseline assessment. The secondary outcomes will be the changes in the Specific Activity Scale, New York Heart Association functional classification, as well as grip strength at 1 week after the baseline assessment.
Discussion
This pilot randomized controlled trial will be the first to evaluate the SPSRS intervention for depressive symptoms in older patients with cardiac disease and StD who are admitted to acute wards. The results will provide tentative indications regarding the impact of the intervention on depressive symptoms among older patients with cardiac disease and StD who are admitted to acute wards, and will contribute to the planning of a full-scale study.

Introduction For those individuals who have suffered an injury to the knee or undergone a surgical intervention, the early recovery of the muscle strength contraction properties of the quadriceps is essential for a favorable recovery and for a return to the activities of daily living and other work- or sports-related activities.
Objectives To evaluate the changes in maximal isometric strength (MIS) of the quadriceps muscle after the application of ultrasound-guided percutaneous neuromodulation (US-guided PNM) on the femoral nerve.
Materials and Methods A case series involving subjects who had previously presented unilateral knee pathology and were in the stage of recovery of quadriceps strength. The subjects were pain-free at the time of the dynamometry measurements, which were performed before and after the application of the US-guided PNM technique. The isometric measurement was performed using the KINEO dynamometry system, performing a preintervention measurement of the mean maximal isometric strength (mMIS) based on 3 repetitions (3 seconds contraction and 6 seconds relaxation). The US-guided PNM technique was performed on the femoral nerve, using the Physio Invasiva CE0120 device (Prim Physio, Madrid, Spain) and a GE Logiq e R7 ultrasound (GE Healthcare, Chicago, IL, USA).
Results In total, 13 subjects participated in the present study. Significant changes were obtained (p < 0.001) in the mMIS of the quadriceps of the affected knee, which progressed from a mean strength of 25.91 kg (standard deviation [SD]: 7.17 kg) to a mean strength of 29.98 kg (SD: 9.06 kg).
Discussion In subjects with knee pathology, the quadriceps muscle is inhibited despite being pain-free during the strength measurements. This process of inhibition can improve with the application of low frequency percutaneous electrical stimulation on the femoral nerve. This technique represents a complementary strategy for the recovery of the normal strength values in pathological knees with or without prior surgery.
Conclusions Ultrasound-guided PNM is an effective technique for the reestablishment of quadriceps strength in inhibited muscles.
The method and condition used for grip strength measurement has an effect on the value. Herein, I present a literature review of the effect of the measurement method and condition on grip strength values. Clarifying the effect of the measurement method and condition on the values makes it possible to accurately judge the evaluation and therapeutic effects and enables highly reliable and valid measurements.
