Abstract
Purpose This study aimed to assess the psychometric properties of the Arabic McGill Quality of Life Questionnaire-Revised (MQOL-R) in breast cancer survivors. Patients and Methods One-hundred-forty breast cancer survivors were recruited and completed the questionnaire. The construct validity was assessed using confirmatory factor analysis (CFA). MQOL-R scores were correlated with Global Health Status/QoL and functional subscales of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) for convergent validity. Reliability was estimated using Cronbach's alpha and intraclass correlation coefficients (ICC). Results CFA reproduced a four-factor model (ie, physical, psychological, existential, and social) with good fit indices (comparative fitting index = 0.980; root mean square error of approximation = 0.091), with all items significantly loading on their respective subscales. The total MQOL-R scores were correlated with the global health status/QoL and functional subscales of the EORTC QLQ-C30 (r = -0.172, P < 0.01). Known-group validity was proven by different MQOL-R scores according to functional status (50.62 ± 6.35 vs 45.98 ± 7.19, P < 0.01). Reliability was supported by good internal consistency and high test-retest correlation coefficients for the Arabic MQOL-R and its subscales (ICC range, 0.83-0.95). Conclusion The Arabic MQOL-R demonstrated adequate construct validity, factor structure, excellent test-retest reliability, and good internal consistency. This tool is valuable for assessing the quality of life in research and physical therapy rehabilitation settings among Arabic-speaking breast cancer survivors.

Abstract
Background Burden of breast cancer it continues to increase largely because of the aging and growth of the world population and assessment of quality of life is an important outcome measure to facilitate and improved care among breast cancer survivors, the aim of this study was to evaluate evidence of reliability, validity, and responsiveness of the Arabic version of the FACT-B + 4 questionnaire among participants with breast cancer related lymphedema (BCRL) in Saudi Arabia.
Methods A prospective cross-sectional study, 51 participants with BCRL completed the Arabic version of FACT-B + 4. Internal consistency and test–retest-reliability were assessed using Cronbach’s alpha, intraclass correlation-coefficient (ICC), and limits of agreement according to the Bland Altman method, respectively. The validation studies were carried-out by examining predefined hypotheses (n = 14) for both construct and Known-groups validity. To investigate the responsiveness, the Arabic version of FACT-B + 4 questionnaire was administrated preoperative and 4 weeks postoperatively among the participants with breast cancer (n = 34). Results The Cronbach alpha of the Arabic FACT-B + 4 total score was 0.90 and for the different subscales ranged from 0.74 to 0.89. Test–retest reliability for FACT-B + 4 total score and different subscales was found to be moderate to very strong (ICC 0.51–0.94). The Bland–Altman plot was adequate − 19.24 and 22.10 points. Measurement variability was acceptable for Arabic FACT-B + 4 and ARM subscale (standard error of measurement = 5.34, and 1.34). Moderate correlations (r = 0.42–0.62) were found between the subscale of the FACTB + 4 and the corresponding domains of SF-36. For known group validity, 72% (10 of 14) hypotheses on known group validity were accepted. Conclusion FACT-B + 4 has adequate psychometric properties, thus making it useful for assessing QOL quality of life in Arabic speaking women with BCRL.

Abstract
Information on the current practices and quantification of lymphedema service may be beneficial to promote and improve the current health care system. Therefore, this study aimed to describe the characteristics of lymphedema practitioners, and lymphedema patients' profiles, and provide a comprehensive picture of lymphedema service provision in Saudi Arabia. A cross‐sectional study design used an online survey to gather data. The survey included information about demographic and professional characteristics of lymphedema practitioners, lymphedema profiles, questions on the services provided, and perceived barriers in providing services. Eighteen lymphedema practitioners (38%) responded to the survey. Most of the respondents were physical therapists (94%), who had completed 135 hours of basic training course, and were certified as lymphedema therapists (89%). Most of these practitioners were in Riyadh (58%), Jeddah (25%), and Dammam (17%). About 75% of patients seen by practitioners had secondary lymphedema, predominately breast cancer‐related lymphedema (47%). The average number of lymphedema practitioners per service is three. The perceived barriers reported included an inadequate number of certified therapists (100%), difficulties with transportation and lack of financial support (each; 72%), and limited space for lymphedema practice/management (89%). The results suggest lymphedema practitioners provide reasonable services for lymphedema patients; however, services are still limited and needs are unmet. Therefore, more staffing is required to promote awareness of the condition and related services, to develop and implement appropriate educational strategies, and improve geographical and multidisciplinary coordination of the services in Saudi Arabia.

Abstract
There is limited evidence regarding the combined effect of exercise and compression garment on breast cancer-related lymphedema (BCRL). Therefore, we investigate the effect of low-intensity resistance training alone or in combination with a compression garment on lymphedema volume, self-reported lymphedema symptoms, and shoulder mobility and function. A total of 60 women with unilateral BCRL were randomly assigned to low-intensity resistance exercises (Rex group, n = 30) or exercises and compression garment (Rex-Com-group, n = 30). Both groups take part in exercises program consisted of 10-12 repetitions at 50 to 60% of one repetition maximum (IRM), three times weekly, for 8 weeks. The primary outcome was lymphedema volume determined by percentage reduction of excess limb volume (ELV). Secondary outcomes were lymphedema symptoms (pain, heaviness, and tightness) and shoulder mobility and function using the disabilities of the arm, shoulder, and hand (DASH) questionnaire. All measurements were standardized and performed before (week 0, W0), after the intervention (week 8, W8), and at follow-up (week 12, W12). A significant reduction in percentage of ELV (p < 0.01), pain severity (p < 0.05), a sensation of heaviness (p < 0.05) and tightness (p < 0.001), and improvement in shoulder range of motion (p < 0.05) and function on DASH scores (p < 0.05) were observed at W8 and W12 in both groups. However, no between-group differences were observed over time. These findings suggest that low-intensity resistance training, irrespective of garment use, can effectively reduce limb volume and lymphedema symptoms, and increase shoulder mobility and function.

Abstract
STUDY DESIGN Cross-sectional and clinical measurement. INTRODUCTION Assessment of hand function considers an essential part in clinical practice. PURPOSE OF THE STUDY To develop normative values of hand grip strength and dexterity function for 6-12-year-old children in Saudi Arabia. METHODS Grip strength and dexterity function was measured in 525 children using Grip Track hand dynamometer (JTECH Medical, Midvale, UT, USA) and 9-hole pegboard test respectively. RESULTS The grip strength and dexterity function was improved as age progressed regardless of gender. Across all age groups, the hand grip strength of boys was significantly higher than girls for dominant hand (31.75 ± 10.33 vs 28.24 ± 9.35; P < .001) and nondominant hand (31.01 ± 10.27 vs 27.27 ± 9.30; P < .001). The girls performed slightly faster than boys for dominant hand (19.70 vs 20.68; P < .05) and nondominant hand (21.79 vs 23.46; P < .05). In general, girls completed a 9-HPT faster than boys in the 2 of 7 age groups: 11 years (9-HPT scores = 2.10 seconds; P < .01) and 12 years (9-HPT scores = 1.93 seconds; P < .01). DISCUSSION The overall patterns of hand grip strength and dexterity function observed in the present study are similar to the previous studies that established acceleration of grip strength with advanced age, and faster performance scores in older children than younger children in both genders. CONCLUSIONS Norms of hand grip strength and dexterity enable therapists to identify some developmental characteristics of hand function among Saudi children, determine the presence of impairment, and compare scores from children in different clinical settings. LEVEL OF EVIDENCE Not applicable.

Abstract
OBJECTIVE This study was conducted to evaluate the efficacy of extracorporeal shock wave therapy (ESWT) on the healing rate, wound surface area and wound bed preparation in chronic diabetic foot ulcers (DFU). METHODS Thirty eight patients with 45 chronic DFU were randomly assigned into; the ESWT-group (19 patients/24 ulcers) and the control-group (19 patients/21 ulcers). Blinded therapist measured wound surface area (WSA), the percentage of reduction in the WSA, rate of healing and wound bed preparation at baseline, after the end of the interventions (W8), and at 20-week follow-up (W20). The ESWT group received shock wave therapy twice per week for a total of eight treatments. Each ulcer was received ESWT at a frequency of 100 pulse/cm(2), and energy flux density of 0.11mJ/cm(2). All patients received standardized wound care consisting of debridement, blood-glucose control agents, and footwear modification for pressure reduction. RESULTS The overall clinical results showed completely healed ulcers in 33.3% and 54% in ESWT-groups and 14.28% and 28.5% in the control group after intervention (W8), and at follow-up (W20) respectively. The average healing time was significantly lower (64.5 ± 8.06 days vs 81.17 ± 4.35 days, p<0.05) in the ESWT-group compared with the control group. CONCLUSION ESWT-treated ulcers had a significant reduction in wound size and median time required for ulcer healing, with no adverse reactions. So, the ESWT is advocated as an adjunctive therapy in chronic diabetic wound.
