Isometric & short arc exercises effect on the quadricep muscle of patello-femoral knee pain patients.

Abstract

Background: Anterior knee pain is the most common problem encountered by clinicians with an estimated prevalence of 15-45% around the globe. Thereby, this study aimed to determine the effects of isometrics and short arc quadriceps exercises on patients with patellofemoral knee pain.
 Methodology: The quasi-experimental study was conducted in Ameen Medical and Dental Centre, Karachi on a total of 80 anterior knee pain patients, including both genders and ages ranging from 16-40 years. The individuals were divided into two equal groups A and B (n=40) which followed isometric and short arc quadriceps exercises regimen, respectively. The pre and post-assessment of pain, muscle activity, muscle thickness measurement, and health-related quality of life (HRQoL) was done using Kujala assessment score, visual analog scale, Electromyography (EMG) biofeedback, and rehabilitative ultrasound imaging, respectively on the first day, 6th and 8th week of exercises session.
 Results: The results showed that pain was much decreased from 1st to 8th week after following Short arc quadriceps exercises (p<0.0001). The results also showed the higher muscle efficacy and HRQoL after following short arc quadriceps exercises, whereas Rehabilitative Ultrasound showed the higher effectiveness of Isometric quadricep exercises in increasing the muscle mass.
 Conclusion: It is concluded that the short arc quadriceps exercises have greater effectiveness in reducing pain, enhancing muscle activity, and increasing the HRQoL, whereas isometric quadricep exercises have shown beneficial effects in increasing muscle mass.

Effect of Quadriceps Isometric Exercise on Reducing Pain in Elderly Communities With Knee Osteoarthritis

“…The increase occurred after observation to control severe pain by 13 respondents and moderate pain by two respondents. There were significant differences in the Numeric Rating Scale (NRS) scores of the intervention group and the control group which showed a decrease in pain in the intervention group with a onemonth treatment time (Anwer and Alghadir, 2014;Hasan et al, 2022;Sengul et al, 2022). This is caused by changes in the length of the quadriceps femoris muscle in the knee joint, which helps stabilize the joint, decreases neuromuscular impulses, and slows axoplasmic transport, thereby reducing the muscle load on the knee joint during activities (Smithard et al, 2022).…”

“…Meanwhile, the National Centers for Health Statistics estimates that 15.8 million (12%) adults between the ages of 25 -74 years have complaints of osteoarthritis (American Rheumatism Association, 2016). The main clinical feature of osteoarthritis is pain (Anwer and Alghadir, 2014;Hasan et al, 2022). Pain is a feeling that osteoarthritis patients complain to doctors when they first come to health services (Anzari, 2018).…”

Association Between Compliance with Quadriceps Strengthening Exercises and Recovery Rate in Patients after Arthroscopic ACL Reconstruction

“…Their academic performance and quality of life may suffer as a result. (15) It is important to address muscular imbalances, particularly those between the hamstrings and quadriceps, in order to stabilize the knee joint. (16) Strength training after recovery should be maintained to aid in the joint's durability.…”
