The goal of this clinical trial is to learn if a novel Knee Extensors Activation (KEA) device can improve quadriceps muscle activation in adults after anterior cruciate ligament (ACL) reconstruction surgery. The study focuses on adults aged 18-45 years undergoing primary unilateral ACL reconstruction, a population commonly affected by this injury.
The main questions it aims to answer are:
Does using the KEA device lead to greater quadriceps muscle activation (measured via EMG) by postoperative Day 5 compared to standard care using a rolled towel?
Does the KEA device improve early knee function, reduce pain, and decrease fear of movement compared to the towel method?
Researchers will compare participants using the KEA device versus a control group using the conventional rolled towel during early postoperative rehabilitation to see if the KEA device provides better outcomes.
Participants will:
Begin quadriceps strengthening exercises on the first day after ACL surgery.
Be randomly assigned to use either the KEA device or a rolled towel for isometric quadriceps exercises.
Perform 3 sets of 10 repetitions of knee extension exercises, twice daily for 5 consecutive days.
Undergo assessment of quadriceps EMG activation and complete questionnaires (KOOS, IKDC, TSK, and VAS) on Day 5.

One of the most common infant developmental diseases is Hip dysplasia which is mostly seen among female' babies and leads to hip instability due to partial or full hip dislocation [1]. Physical therapy's role plays a significant role in treating hip dysplasia by creating new walking habits as an adaptation way and compensation for the deformity [3]. Focusing on the muscles that produce hip abduction force is a basic item of the hip dysplasia rehabilitation program [4]. Cross-legged sitting position can be considered as a common and easy position that might enhance the range of motion of the lower limb joints [5].
While unilateral hip developmental dysplasia has been widely distributed among newborns, especially in the last few years, the role of engaging the cross-legged sitting technique as a part of physical therapy and rehabilitation programs on improving the temporospatial parameters, muscular electrical activity and foot pressure distributing is still not clear. Therefore, this study aimed to analyze the effects of engaging the cross-legged sitting technique as a part of physical therapy and rehabilitation program among patients with UHDD by comparing the group who participated in rehabilitation program with CLS to the other without.
To understand the importance of including Cross-legged sitting technique in physical therapy and rehabilitation program of Unilateral Hip Developmental Dysplasia (UHDD) to enhance the spatial and temporal measures, achieving a healthy distribution of foot pressure, increasing the electrical activity of lower limb muscles and improving the overall gait pattern.
No risks at all. All instruments and techniques in this study are safe and used regularly without any hazards.
The data will be stored and archived on a password-protected computer for safety and security purposes. After accomplishing the research and getting the outcomes, the results of the research may be published as an academic article in a peer-reviewed journal. In another word, no personal data will be published at all.
Taking part in the study and withdrawing at any time is completely voluntary with no need to give any reason.

This is a double-blind, randomized controlled trial comparing WBV therapy with a placebo intervention and standard care. A total of 150 participants will be recruited and investigated from Prince Mutib Hospital. Participants will be randomly allocated to one of three groups: WBV therapy, placebo (non-vibrating platform), or control (standard care). The study duration will be 12 weeks, with assessments conducted at baseline, post-intervention (12 weeks), and at a 6-month follow-up.
