ObjectiveTo compare the effects of low intensity ultrasound (LIUS), traditional exercise therapy (TET), low level laser therapy (LLLT) and TET on temporomandibular joint (TMJ) pain and trismus following recovery from head and neck cancer (HNC).MethodsSixty participants following, who had experienced HNC, were randomly allocated to three groups of 20 people each. Each group received different therapy. Group A received LIUS and TET; group B received LLLT and TET; while group C received TET. All 60 participants were evaluated under the visual analog scale (VAS), the University of Washington Quality of Life questionnaire (UW-QOL) and the Vernier caliper scale (VCS) at the beginning of the therapies and after 4 weeks.ResultsANOVA test revealed significant improvements across all three groups with outcomes of p<0.05. The results of the UW-QOL questionnaire showed a significant difference between groups A, B and C in favor of group A (p<0.05). The VAS results showed a more improvement in group A as compared to group B (p<0.05), while there was no statistical difference between groups B and C (p>0.05). The VCS results showed more improvement for the individuals in group B as compared to those in group C (p<0.05), while there was minimal difference between groups A and B (p>0.05).ConclusionThe LIUS and TET are more effective than LLLT and/or TET in reducing TMJ pain and trismus following HNC.

BackgroundObesity is very common worldwide and is related to critical morbidity and mortality. It has a large number of impacts on the human body. Constipation has a prevalence from 4% to 29% in various parts of the world and is considered to be a major health problem, with an estimated incidence of 5% in males and 15% in females. There is a strong association between obesity and constipation. This study aimed to investigate the effect of physical activity and a low-calorie diet on constipation in middle-aged obese women.MethodsThis study included 125 obese women (age 20–40 years) who had chronic constipation. Participants were randomly assigned to two groups. Group A included 62 women who received a suggested protocol of physical activity, a low-calorie diet, and the routine standard care for constipation, whereas Group B included 63 women who received only the standard medical care for constipation and a low-calorie diet. Both groups followed the program for 12 weeks. Changes in the Patient Assessment of Constipation Symptoms (PAC-SYM) and Patient Assessment Quality of Life (PAC-QOL) scores, and in the body mass index (BMI) were recorded in study subjects, both at baseline and at the end of the study program.ResultsThere were no statistically significant differences in the baseline characteristics of patients in the two groups. After 12 weeks of intervention, both groups showed significant intra-group differences (p < 0.05) in all of the measured variables, except the BMI which showed a nonsignificant difference (p > 0.05) in Group B. Between-groups comparison showed significant differences (p < 0.05) in all of the measured parameters in favor of Group A.ConclusionPhysical activity and weight reduction improve PAC-SYM and PAC-QOL scores in middle-aged, premenopausal women with constipation in the short term (up to 12 weeks).

Objectives Nigella sativa oil, ultrasound, and moist-exposed burn ointment (MEBO) have been suggested as noninvasive treatments for a number of inflammatory conditions and to accelerate wound healing. The aim of this study was to evaluate the efficiency of pulsed and continuous modes of ultrasound either alone or through phonophoresis, with N. sativa oil, or MEBO ointment in the treatment of chemical burns. Methods Thirty-five local rabbits were randomly divided into seven equal groups: pulsed ultrasound, continuous ultrasound, topical N. sativa oil, pulsed phonophoresis, continuous phonophoresis, topical MEBO ointment, and control group. Wound surface area was measured on days 0, 7, 14, and 21 using metric graph paper and photographs. Results Significant differences were found between pre- and post-treatment wounds in all groups, except for the control group, in favor of the pulsed phonophoresis. In contrast, low results were found in favor of continuous ultrasound. Conclusion Ultrasound, topical application of N. sativa oil, phonophoresis, and MEBO ointment have the potential to accelerate wound healing induced by chemical burns. Such treatment modalities may be used to treat wounds.

TENS may be an alternative safe treatment for LP-induced itching.
