Effect of The Trunk Muscle Stabilization Training on Balance for Chronic Stroke Patients

The effect of a trunk stabilization exercise program using weight loads on balance and gait in stroke patients: A randomized controlled study

BACKGROUND: The effects of trunk stabilization exercise programs and exercises applying weight loads for stroke patients are well presented. However, there is not enough objective research to prove the effects of trunk stabilization exercise programs using weight loads for stroke patients. OBJECTIVE: In this study, a trunk stabilization exercise program using weight loads was performed to investigate its impact on the balance and gait ability of stroke patients. METHODS: Thirty patients with stroke were randomly divided into three groups. Experiment group 1 followed a trunk stabilization exercise program using weight loads, experiment group 2 followed a trunk stabilization exercise program, and the control group followed general physiotherapy. Patients’ balance ability was assessed using balance measurement equipment BT-4 (postural sway area (PSA), postural sway length (PSL), limit of stability (LOS)), Berg Balance Scale (BBS), and Time Up and Go test (TUG). Gait speed was measured to examine gait ability. RESULT: After the intervention, the PSA, PFSL in experimental groups 1 and 2 decreased but that of the control group increased. BBS, TUG, and LOS scores of experimental group 1 were significantly improved compared to experimental group 2 and the control group. Also, gait speed was significantly improved in experimental group 1 compared to experimental group 2 and the control group. CONCULSION: This study may be used as a basic material for an effective trunk stabilization exercise method for stroke patients and might be of significance as an intervention method for stroke patients requiring long-term treatment.

Effects of diaphragm and deep abdominal muscle exercise on walking and balance ability in patients with hemiplegia due to stroke

The aim of this study was to investigate the effects of diaphragm and deep abdominal muscle exercise (DDAME) on walking ability (WA) and balance ability (BA) in subjects with hemiplegia due to stroke. Study subjects consisted of twenty patients diagnosed with hemiplegia due to stroke. They were randomized into a control group (CG) (n=10) that performed traditional exercise and an experimental group (EG) (n=10) that performed DDAME. The WA was measured using the 10-m walking test (10MWT) and 6-min walk test (6MWT). The BA was measured using the Timed Up and Go test (TUG) and Berg’s balance scale (BBS). Paired t-test was performed to compare differences within the groups before and after intervention. The analysis of covariance was performed to compare the differences between the EG and CG. The level of significance was set at α=0.05. Within-group changes in 10MWT and 6MWT were significantly different in both the EG (P<0.05) and CG (P<0.05). There was significantly more improvement in the 10MWT and 6MWT in the EG than in the CG (P<0.05). Within-group changes in TUG and BBS were significantly different in both the EG (P<0.05) and the CG (P<0.05). There was significantly more improvement in TUG and BBS in the EG than in the CG (P<0.05). DDAME program, with diaphragm and inspiratory muscle strengthening exercises, is needed for patients experiencing difficulty in WA, BA, trunk asymmetry, abnormal alignment, mobility of trunk muscles, power, or endurance decline.

Application of massage for ankle joint flexibility and balance

[Purpose] The purpose of this study is to examine the effect of calf muscle massage on ankle flexibility and balance. [Subjects and Methods] The study's subjects were 32 healthy college students, divided into two groups according to the massage methods applied. Both groups received five-minutes of massage to each calf, making a total of ten minutes. Massage group A received effleurage, tapotement and pressure, and massage group B received effleurage, friction and petrissage. The functional reaching test and the modified one leg standing test were performed to measure the flexibility and balance of the ankles both before and after the massage application. [Results] In the functional reaching test performed after the calf muscle massage intervention, both groups showed significant increases. However, no significant differences were found between the two groups. In the modified one leg standing test, massage group A showed a significant increase in flexibility and balance after the intervention only when the left foot was used for support. Massage group B showed a significant increase when each foot was used for support. A significant difference between the groups was only observed only when the left foot was used for support. [Conclusion] Calf muscle massage may be effective for enhancing the flexibility and balance function of the ankle joint. In particular, a combined application of friction and petrissage massage techniques may be more effective for increasing ankle joint flexibility. Therefore, the application of calf massage can be considered an appropriate method for improving balancing ability.

Effect of spinal decompression on the lumbar muscle activity and disk height in patients with herniated intervertebral disk

[Purpose] This study was conducted to clarify the difference in therapeutic effects between traction and decompression therapies, and their clinical therapeutic significance. [Subjects and Methods] The subjects were 31 patients aged 35 to 50 years who had unilateral or bilateral lumbar and radicular leg pain. An intervention program was implemented in 31 patients with lumbar herniated intervertebral disks. For the experimental group, 15 subjects were randomly selected to receive decompression therapy and trunk stabilization exercise. For the control group, 16 subjects were randomly selected to receive traction therapy and trunk stabilization exercise. [Results] Activities of the rectus abdominis, transverse abdominis, and external oblique muscles increased significantly in both groups. However, the activity of the erector spine muscle decreased, which was the only significant change in muscle activity among those of the other muscles in both groups. The disk herniation index in the experimental group decreased significantly in comparison with that in the control group, and the difference in the change in disk herniation index between the groups was significant. [Conclusion] Decompression therapy was demonstrated to be more effective clinically than conventional traction therapy as an intervention method for disk disease.

The effects of trunk stabilization exercise on bone density after menopause

[Purpose] This study examined the effect of low intensity exercise on bone density by conducting trunk stabilization exercise on females after menopause for 24 weeks. [Subjects and Methods] Thirty three female subjects over 47 years old and under the age of 53 were selected and 16 for experimental group and 17 for control group were randomly selected. Experimental group had performed spinal and pelvic stabilization exercise 30 minutes a day, 5times a week, for 24 weeks. Except for the daily life, control group did not participate in any characteristic movement. Bone density of every member in experimental group was measured using average value of bone density of 1st-4th lumbar through quantitative computer tomography. [Results] There was a meaningful difference in only control group about measured value of bone density within each group, experimental and control group, but there was no meaningful difference in measured value of bone density between two groups, experimental group and control group. [Conclusion] Through this research, we could see the fact that although trunk stability exercise could not change bone density meaningfully, it could maintain bone density. In the future, it is randomly necessary to study things related this because results of researches can show different results according to exercise intensity, exercise period, age, weight, hormone status and mediation period. It is considered that it will help to prevent and treat patients with osteoporosis a lot.
