The effects of ankle loads on balance ability during one-leg stance

Effectiveness of an 8-week overground walking with paretic lower limb loading on spatiotemporal gait parameters and motor function among chronic stroke survivors: a protocol for randomised controlled trial

BACKGROUND

Post-stroke gait deviations contribute to significant functional disability, impaired walking ability and poor quality of life. Prior studies suggest that gait training with paretic lower limb loading may improve gait parameters and walking ability in post-stroke. However, most gait training methods used in these studies are not readily available, and studies using cheaper methods are limited.

OBJECTIVE

The purpose of this study is to describe a protocol for a randomised controlled trial on the effectiveness of an 8-week overground walking with paretic lower limb loading on spatiotemporal gait parameters and motor function among chronic stroke survivors.

METHODS

This is a two-center, single-blind, two-arm parallel randomised controlled trial. Forty-eight stroke survivors with mild to moderate disability will be recruited from two tertiary facilities and randomly assigned into two intervention arms; overground walking with paretic lower limb loading or overground walking without paretic lower limb loading in a 1:1 ratio. All interventions will be administered thrice weekly for 8 weeks. Primary outcomes will be step length and gait speed whereas the secondary outcomes will include step length symmetry ratio, stride length, stride length symmetry ratio, stride width, cadence and motor function. All outcomes will be assessed at baseline, 4, 8 and 20 weeks after the start of intervention.

DISCUSSION

This will be the first randomised controlled trial to report the effects of overground walking with paretic lower limb loading on spatiotemporal gait parameters and motor function among chronic stroke survivors from low-resource setting.

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.

Is Ankle Kinesio Taping Effective to Immediately Change Balance, Range of Motion, and Muscle Strength in Healthy Individuals? A Randomized, Sham-Controlled Trial

Background

The ankle–foot complex plays a key role in maintaining balance because it collects proprioceptive data. Kinesio taping (KT) is a rehabilitative method performed by the cutaneous application of a special elastic tape. The mechanical correction technique of KT was suggested to reposition the joints and alter balance parameters. The aim was to reveal the pure effects of ankle KT on balance, range of motion (ROM), and muscle strength in healthy individuals.

Methods

Forty healthy students were recruited for this randomized, sham-controlled study at a local university. Participants were divided into two groups—experimental and sham application groups. The primary outcome measures were balance parameters. Athlete Single Leg (ASL), Limits of Stability (LoS), and Clinical Test of Sensory Interaction and Balance (CTSIB) were used to measure single-leg dynamic balance, dynamic postural control, and sensory interaction of balance, respectively. Dorsiflexion ROM and dorsiflexor muscle strength were the secondary outcomes.

Results

The ASL score showed significant improvement only in the experimental KT group (P=0.02); however, the LoS score increased significantly in both groups (P<0.05). CTSIB scores, dorsiflexion ROM, and dorsiflexor muscle strength for both ankles did not change in any of the groups after intervention (P>0.05). Moreover, there was no superiority of one intervention over the other in improving any of the variables (P>0.05).

Conclusion

The mechanical correction technique of KT can be useful in providing immediate improvement in single-leg dynamic balance in healthy individuals. However, it may not be effective to significantly change the sensory interaction of balance, dorsiflexion ROM, and muscle strength.
