简要总结
The aim of the study was to evaluate the impact of inertial rehabilitation on: shoulder flexors, extensors and shoulder abductors and adductors strength, breast cancer-related lymphedema (BCRL) and quality of life in women after mastectomy. Twenty-four women after mastectomy were randomized to a training (T; n = 12) or control group (C; n = 12). The T group performed inertial training twice a week for 6 weeks using a Cyklotren inertial device. Each training session included warm-up and 4 sets of shoulder flexors, extensors, abductors, and adductors, with the right and left arms worked. The training loads for all exercises was equal 5 kg. Before and after training the maximum force of trained muscles was tested under training conditions. Body composition, BCRL, disabilities of the arm, shoulder and hand (DASH) were also evaluated. Inertial rehabilitation caused significant improvement in strength in all tested muscles in T whereas changes in C were insignificant. Quality of life evaluated by DASH score decreased significantly in T and and did not change in C. Moreover, BCRL and body composition did not change significantly following intervention in both groups. Inertial exercises can be useful rehabilitation method in women treated for breast cancer.
详细描述
A group of 30 women who underwent mastectomy procedure attended an initial meeting and all of them agreed to participate in the study. The participants were members of an association of people after mastectomy (Amazons Association) and regularly participated in rehabilitation gymnastics twice a week for at least 3 years. All women met the including criteria: mastectomy was performed at least 6 months before the study, lack of: fractures in the prior 3 months, tendon and ligament injuries in the prior 2 months, serious heart disease, cerebral palsy, and limb amputations. All subjects received permission from their physician to participate in the experiment. Therefore, the study finally included 24 women after mastectomy (age, 66.2 ± 10.6 years, range 43-82 years; body mass, 72.7 ± 10.6 kg; height, 159 ± 5.2 cm), 17 after simple mastectomy and 7 after breast conserving therapy. The participants were randomly allocated into two groups: a training group (T; n = 12) and a control group (C; n = 12) using chit method. The T group participated in 6 weeks of inertial training while the control group maintain their normal daily activity. All women still participated in rehabilitation gymnastics twice a week. All participants gave written informed consent to take part in the study.
Testing
Before and after training participants were evaluated using the following tests:
- strength of shoulder muscles measurements
- body composition measurements
- breast cancer-related lymphedema (BCRL) evaluation
- disabilities of the arm, shoulder and hand test (DASH)
Strength of shoulder muscles measurement. Strength of shoulder flexors and extensors and strength of shoulder abductors and adductors were tested in the standing position using Cyklotren inertial device (Naczk 2015). After warm-up, each participant performed a 10-second maximal test of the right and left arm separately, with a 2-minute break between measurements. Participants position during strength testing and inertial training is showed on Figure1. For all measurement 5 kg load was applied. It should be noted here that the same load during inertial training doesn't mean the working muscles develop the same force. During inertial exercise force developed by muscle strongly depend on movement velocity, greater movement velocity results greater muscle load and greater force is developed (the force value is presented on-line on the Cyklotren's screen). The range of motion was approximately 90 degree (where 0 degrees corresponded to the arm along the trunk). Data collection was preceded by a familiarization session.
