Abstract
Aim. This pretest-posttest controlled study investigated the effects of core exercises on knee pain, disability, proprioception, and quadriceps strength in patients with knee osteoarthritis (KOA).
Materials and Methods. Eighty patients aged from 40-65 years with mild to moderate KOA were recruited from Cairo University hospitals. They were randomly assigned into two equal groups; group A received core exercises plus conventional exercises and group B received conventional exercises only. Sessions were done 3 times weekly for 4 weeks. Patients were evaluated, pre-and post-treatment, for knee pain (using visual analogue scale), disability (using aggregate locomotor function), proprioception (using inclinometer), and quadriceps strength (using dynamometer).
Results. There were no significant differences between groups post-treatment (p-value > 0.05). There was a significant improvement in quadriceps strength in group (A&B) and pain and disability in group (A) post-treatment (p-value < 0.05).
Conclusions. Adding core exercises to conventional exercises showed a trend towards significance in reducing pain and disability than conventional exercises alone in KOA. On the other hand, conventional exercises with or without core exercises improved quadriceps strength rather than proprioception. Hence, further studies on a larger sample are promising.

Abstract

Background. Limitation in knee range of motion (ROM) is frequently compromised in patients with patellofemoral pain syndrome (PFPS). Smartphones have become the most widely used device and begun to enter the field of musculoskeletal evaluation. Objective. to investigate the concurrent validity and reliability of the smartphone “Goniometer Records” application in assessing knee ROM in patients with PFPS. Methods. thirty-six PFPS patients (age: 22.82 ± 1.76 years, male:28, female:8) were participated. Knee ROM was measured simultaneously by the smartphone “Goniometer Records” application and by the bubble inclinometer. These measurements were repeated by the same experienced examiner on the same day to measure intra-rater reliability, and by another experienced examiner on the same day to measure inter-rater reliability and after one-week to measure test-retest reliability Results. There was a strong positive correlation to confirm concurrent validity between the smartphone application and the bubble inclinometer (r = 0.97-0.98; p = 0.0001. Intra-rater, inter-rater and test-retest reliabilities of smartphone application suggested excellent reliability for knee flexion and extension (ICC = 0.988-0.997), (ICC = 0.985-0.994), (ICC = 0.984-0.994) respectively. Conclusion. Smartphone application is a valid and reliable alternative for bubble inclinometer in measuring active knee ROM in patients with PFPS.
