Virtual reality balance training versus core stability exercises on balance in patients with unilateral lymphedema

Purpose: The purpose of this study is to compare the effects between Wii fit balance board and core stability exercises on balance dysfunction in patients with unilateral lymphedema. Method: Sixty patients (women) aged 40-60 years with grade 1 or 2 lymphedema were randomly assigned into the following two groups. Group A received the Wii fit balanced exercises for three times per week for four weeks as total treatment duration in form of (Ski Slalom, Advanced Skiing, Ski Jumping followed by Header and Jump Rope).; Group B received core stability exercises for 4 weeks (3times/week) in form of {1- Abdominal bracing (10 repetitions x10 second holds), 2- Curl up (3 sets x 10 repetitions), 3- Supine bridge (3 sets x 10 repetitions), 4- Supine unilateral bridge (3 sets x 10 repetitions for each leg), 5- Plank (3 sets x 10 repetitions) and 6- Bird dog (3 sets x 10 repetitions for each limb)}. Balance was determined using time up and go (TUG) and Wii fit results by using the Wii fit balance board. Balance was measured before and 4 weeks after the treatment program. 

Virtual Reality as a Promising Tool Supporting Oncological Treatment in Breast Cancer

Breast cancer (BC) treatment is associated with many physical and psychological symptoms. Psychological distress or physical dysfunction are one of the most common side effects of oncological treatment. Functional dysfunction and pain-related evasion of movement may increase disability in BC. Virtual reality (VR) can offer BC women a safe environment within which to carry out various rehabilitation interventions to patient support during medical procedures. The aim of this systematic review was to conduct an overview of the clinical studies that used VR therapy in BC. The review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines method: the initial search identified a total of 144 records, and 11 articles met the review criteria and were selected for the analysis. The results showed that VR seems to be a promising tool supporting oncological treatment in BC patients. VR can have a positive effect on mental and physical functions, such as relieving anxiety during oncotherapy, diminution pain syndrome, and increasing the range of motion and performance in daily activities.

A quasi-randomized clinical trial: virtual reality versus proprioceptive neuromuscular facilitation for postmastectomy lymphedema

BACKGROUND

Postmastectomy lymphedema can be considered the main cause of upper extremity functional impairment in patients with breast cancer. Fatigue, pain, and limited range of motion are common symptoms. If left untreated, lymphedema causes cellulitis, which can lead to gangrene in rare cases. This study was carried out to identify and compare the therapeutic advantages of virtual reality-based exercises and proprioceptive neuromuscular facilitation for postmastectomy lymphedema. Thus, a quasi-randomized comparative study of thirty female patients with unilateral postmastectomy lymphedema was conducted. Fifteen patients performed virtual reality-based exercises as well as manual lymphatic drainage, pneumatic compression, and home programs, while the other fifteen patients performed proprioceptive neuromuscular facilitation as well as manual lymphatic drainage, pneumatic compression, and home programs. The excess arm volume between the healthy and affected limbs was estimated before and after eight sessions of treatment for both groups. In addition, the affected limb functional score was calculated. Arm volume was calculated by the truncated cone formula and girth measurements obtained by the circumferential method. The Arabic version of the QuickDASH-9 scale was used to assess extremity function.

RESULTS

The excess arm volume significantly decreased in both the virtual reality group (p = 0.001) and proprioceptive neuromuscular facilitation group (p = 0.005), and there was no significant difference between the two groups (p = 0.902). Age was inversely related to the improvement percentage of the QuickDASH-9 score in the virtual reality group. The functional improvement percentage was statistically significantly different between the two groups (p = 0.045).

CONCLUSION

It can be concluded that both virtual reality and proprioceptive neuromuscular facilitation have a beneficial therapeutic effect on edema in patients with unilateral postmastectomy lymphedema; neither method was found to be superior, except virtual reality was found to be superior to proprioceptive neuromuscular facilitation in motivating patients and providing visual feedback.
