“…2 other individuals suff ered a spontaneous vitreous hemorrhage and a localized posterior vitreous detachment. One of these individuals reported a decrease in visual acuity 5-min after being exposed to a 20-min session of WBVE [ 16 ] , while the other individual's symptoms occurred 2-weeks after starting a WBVE program twice a week for 20-min [ 2 ] . The motion of the eyes during vibration is complex; being determined by the transmission of vibration to the head as well as between the head and the eye [ 17 ] .…”

“…These characteristics include the type (SV, side-alternating), frequency, magnitude, and duration of exposure. Recent training studies have used input frequencies (10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26) that are close to resonance of the whole body, spine and head [ 5 , 24 ] . In both cases the vibration exposure consisted of either 'standing' or static squatting for 60-s repetitions.…”

Transmission of Acceleration from a Synchronous Vibration Exercise Platform to the Head

Exercise vibration platforms are becoming commonplace in homes and fitness centers. However, excessive mechanical energy transferred to the head and eye can cause injury. The purpose of this study was to evaluate how changes in platform frequency and knee flexion angle affect acceleration transmission to the head. Participants (N=12) stood on a whole-body vibration platform with knee flexion angles of 0°, 20°, and 40° to evaluate how changes in knee flexion affected head acceleration. 7 specific platform frequencies were tested between 20-50 Hz at 2 peak-to-peak displacement settings (1 and 2 mm nominal). Accelerations were measured with triaxial accelerometers at the platform and head to generate transmissibility ratios. Platform-to-head transmissibility was not significantly different between the 2 platform peak-to-peak amplitudes (P>0.05). Transmissibility measures varied depending on platform frequency and knee angle (P < 0.05). Flexing the knees resulted in reduced head transmissibility at all frequencies (P<0.05). Platform-to-head transmissibility values exceeded 1.0 at both 20 and 25 Hz platform vibration frequencies with the knees in full extension. To reduce the risk of injury to structures of the head during vibration exercise, using platforms frequencies below 30 Hz with small knee flexion angles (< 40°) should be avoided.

“…Bertschinger & Dosso [60] reported the case of a 43 year old man who presented with a uniocular drop in vision, the only reported change in recent activity was the introduction WBV for a period of two weeks prior to developing the condition. More recently it has been reported [61] the case of vitreous haemorrhage with localised posterior retinal detachment in a 52 year o ld male. The patient presented with a uniocular drop in vision following a single session of WBV.…”

Whole body vibration has received much attention as an innovative approach to exercise, lead ing to constantly increasing attention fro m the scientific co mmunity. Previous research considering occupational vibration has illustrated the risks associated with high levels of exposure to vibration; however during vibrat ion exercise the exposure duration is much shorter and therefore the potential comp licat ions must be reconsidered. This review brings together research from various aspects of occupational vibrat ion, clin ical research and vib ration exercise to address issues within the context o f health and safety with a part icular focus on neurophysiological and neurovascular responses. The results indicate that peripheral nerve and blood vessels are exposed to risks such as compression, shear stress and altered function as a response to vibration. However, correct planning and implementation of exercise protocols should effectively control these risks. By summarising the areas that have received attention an overview of potential co mplications will be achieved; with an understanding of which factors prevent participation and those that simp ly require an amended approach to vibration exercise.

“…We present a case report of a patient who developed both a retinal tear and vitreous hemorrhage soon after whole-body vibration training. In current literature, there have only been two documented cases of vitreous hemorrhage following whole-body vibration exercise [1,2]. Both of these papers suggest a high probability of correlation between whole-body vibration training and subsequent vitreous hemorrhage.…”

Background: The purpose of this report is to describe the occurrence of a retinal tear, pre-retinal and vitreous hemorrhages after completing a session of whole-body vibration training. Though our patient is the third documented case of vitreous hemorrhage following whole-body vibration training, he is the first to show a close association of a retinal tear and vitreous hemorrhage with whole-body vibration training. Case presentation: This case report describes a 59-year-old male who had acute onset of floaters and shadows in the left eye. The results of the examination revealed a temporal retinal tear, inferior pre-retinal hemorrhage, and mild vitreous hemorrhage. He was successfully treated using laser photocoagulation with resolution of vitreous and pre-retinal hemorrhages on 4-month follow up. Conclusions: With the rise in popularity of whole-body vibration training exercise, it is important for the medical and athletic community to be aware of possible associated ocular complications. We believe that high-force vibration training may cause retinal tears in susceptible persons.
