Effects of Whole Body Vibration in People With Chronic Stroke
The overall aim of the proposed study is to determine whether whole body vibration is beneficial in promoting bone health, physical fitness and neuromotor performance in patients with chronic stroke.
Subjects in the experimental group will undergo whole body vibration therapy (1 session per day, 3 sessions per week) for 8 weeks. The vibration frequency used in this study will be 30Hz. The total duration of exposure to vibration for the experimental group will be 10 minutes. While standing on the vibration platform, patients will be instructed to repeat the following set of light exercises: (1) light squatting,(2) deep squatting, (3) side-to-side weight-shift, (4) Forward and backward weight-shift, (5) forward lunge, (6) marching on the spot. The control exercise group, on the other hand, will perform the same exercise program on the platform, but no vibration will be given. The training will be conducted by a qualified personnel with physiotherapy background.
The outcome measurement will be performed 4 times: (1) immediately before the commencement of intervention, (2) 4 weeks after the intervention started, (3) immediately after termination of treatment, (4) at 1 month after termination of treatment. Each subject will be evaluated for bone markers, leg muscle strength, balance, sensory function ,spasticity, and walking ability.

Medical and Biotech [MESH] Definitions
An occupational disorder resulting from prolonged exposure to vibration, affecting the fingers, hands, and forearms. It occurs in workers who regularly use vibrating tools such as jackhammers, power chain saws, riveters, etc. Symptoms include episodic finger blanching, NUMBNESS, tingling, and loss of nerve sensitivity.
Rough, noisy breathing during sleep, due to vibration of the uvula and soft palate.
A continuing periodic change in displacement with respect to a fixed reference. (McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)
The hearing and equilibrium system of the body. It consists of three parts: the EXTERNAL EAR, the MIDDLE EAR, and the INNER EAR. Sound waves are transmitted through this organ where vibration is transduced to nerve signals that pass through the ACOUSTIC NERVE to the CENTRAL NERVOUS SYSTEM. The inner ear also contains the vestibular organ that maintains equilibrium by transducing signals to the VESTIBULAR NERVE.
A method of speech used after laryngectomy, with sound produced by vibration of the column of air in the esophagus against the contracting cricopharyngeal sphincter. (Dorland, 27th ed)
The overall aim of the proposed study is to determine whether whole body vibration is beneficial in promoting bone turnover, physical fitness and neuromotor performance in patients with su...
This study will examine whether whole-body vibration slows down bone loss in healthy postmenopausal women with osteopenia. Whole-body vibration is a promising novel therapy that involves s...
There is general agreement that physical exercise can positively influence osteoporotic fracture risk along two pathways: first by reducing the risk of falls via an improvement of fall rel...
This is a prospective randomized controlled trial investigating the effect of vibration therapy on bone mineral density (BMD) and bone quality in AIS subjects suffering from osteopenia (lo...
The purpose of this study was to investigate the acute and chronic effect of whole-body vibration exercise on serum insulin-like growth factor-1 levels in women with fibromyalgia (FM). It...
Objective: Low intensity vibration as a therapeutic and training modality has received increased attention despite the lack of clear mechanistic pathways. Thus, to determine mechanisms underpinning vi...
[Purpose] This study compared the effects of sling exercises with and without vibration on the muscular activity of the internal oblique (IO), rectus abdominis (RA), multifidus (MF), and erector spina...
Exogenous stimulation of skeletal muscle or tendon is often used to improve range of motion. Despite substantial research efforts, however, the effects of vibration on flexibility have not been clarif...
The study aimed to establish the short- and long-term effects of vibration on postural stability in young men. A single set of exercises and a 4-week vibration training were assessed for their impact...
In this study, we examined the interaction between central and peripheral proprioceptive afferent pathways by applying ankle tendon vibration during postural leaning in different directions. Twenty yo...
