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
Introduction. Postnatal Pelvic girdle pain (PGP) is common complaint in women all over the world and it has a major impact on health and functioning as it decreases quality of life. The start of PGP is typically by weeks 17–19 of gestation, with a peak of occurrence by weeks 24–36 postpartum continuation. Studies have shown that 5–27% of the women had persisting pain 1–3 months after delivery. Methods. Ninety postnatal women’s was randomly classified into three groups, Group (A): Contains of 30 women’s treated with pelvic stabilization exercises. Group (B): Contains of 30 women’s treated with low-level laser therapy only and group (C): Contains of 30 women’s treated with pelvic stabilization exercises and low-level laser therapy all groups remain twelve sessions over six week’s period by two sessions per week. Visual analogue scale, serum cortisol level, pelvic girdle questionnaire, Faber test and P4 test were measured and compared at 0 and 6 weeks after the treatment in the three groups. Results. All groups improved significantly from pretests to posttests score on both outcome measures of VAS, PGQ, cortisol level, Faber test and P4 test p = 0001. These data support the findings that when patients are unable to exercise, low level laser therapy is an appropriate alternative for pain reduction and increased daily function for individuals suffering from postpartum pelvic girdle pain. Conclusion. Our Results revealed that laser therapy accompanied with pelvic Stabilisation exercise is effective in improving postpartum pelvic girdle pain reducing, pain stress, decrease disability and improve activity of daily level.
