Abstract

As the level of restrictions on community activities (PPKM) decreased, more institutions and organizations began to conduct basketball competitions as a result of the broad popularity of the sport. The intensity of practice has increased as a result of the competitive atmosphere. As a result of increased training intensity, there is an increase in player injuries sustained during practice or competition. This study aimed to explore basketball coaches' beliefs toward injury in student-athletes, particularly at the high school and university levels. The study employed a survey approach, with the target group consisting of basketball coaches at the high school and university levels in Malang, East Java. According to the study's findings, individual factors affecting players put the most significant pressure to play during an injury. Additionally, the coach is the second most influential factor in pressuring injured players to play, trailing only teammates and parents. Among the themes that emerged from this study on injury-related knowledge and beliefs were the determination to win, the significant role of the participants, and the ability to serve as a source of motivation for other players.

Abstract

Background: Low-Level Laser Therapy (LLLT) and High-Intensity Laser Therapy (HILT) are widely used nonpharmacological interventions for patients with knee osteoarthritis (KOA). However, scientific evidence comparing the effectiveness of these two therapies on functional outcomes remains limited. Objective: To compare the effects of LLLT and HILT combined with quadriceps bench exercises on knee function, walking speed, and knee proprioception in patients with KOA. Methods: This randomized controlled trial used a pretest–posttest design at Dr. Saiful Anwar Regional General Hospital, Malang. Patients with KOA were randomly assigned to LLLT or HILT groups, with both receiving quadriceps exercises for four weeks. Knee function, walking speed, and proprioception were assessed using KOS-ADLS, 10MWT, and joint position sense tests. Pre- and post-intervention changes were statistically compared within and between groups. Results: Both LLLT and HILT produced significant improvements in functional outcomes after four weeks of intervention. Improvements in knee function were observed in both groups, with no significant between-group difference. Walking speed increased significantly in both groups; however, the LLLT group demonstrated a significantly greater improvement than the HILT group (p = 0.030). Regarding proprioception, a significant improvement was observed only in the LLLT group, although no significant between-group difference was found following the intervention. Conclusion: The findings suggest that LLLT may be considered an effective noninvasive adjunctive therapy for improving mobility in patients with KOA.
