“…The following subjects were excluded: (1) subjects who required aids to walk independently, (2) those with severe musculoskeletal disorders or foot and toe deformities that interfered with walking, (3) subjects with neurological impairments or vestibular dysfunction interfering with balance diagnosed by an neurotologist based on vertical axis rotation, positional, and oculomotor testing 18) , (4) subjects with orthostatic hypotension, (5) subjects with significant cognitive dysfunction who had difficulty understanding instructions (cognitive impairment was defined as a score of 24 or below on the Mini-Mental State Examination) 19) , (6) subjects taking medications that affected their balance ability, and (7) subjects with sensory impairment or diabetic peripheral neuropathy in the lower limbs. All participants signed an informed consent form after receiving a full explanation of the purpose of this study.…”

Abstract.[Purpose] We compared the differences in individual toe flexor muscle strength and balancing ability between elderly fallers and non-fallers and determined the correlation between individual toe flexor muscle strength and the functional reach test (FRT).[Subjects] Thirty community-dwelling older adults (15 fallers and 15 age-and sexmatched non-fallers) between 65 and 83 years of age participated in this study.[Method] Individual toe flexor muscle strength was measured using a dynamometer, and balance ability was assessed with the FRT, Berg balance scale, and a sensory organization test (SOT).[Results] The hallux and second toe flexor muscle strengths in the non-faller group were significantly stronger bilaterally than those in the faller group, whereas no significant differences in the third and fourth toe flexor muscle strengths were found. The individual toe plantar flexor muscle strengths were moderately correlated with FRT(r = 0.489-0.765). The non-faller group showed significantly greater balance ability in the FRT and SOT than the faller group.[Conclusion] The results of this study suggest that the force-generating capability of the hallux and second toe flexor muscle are related to the incidence of falls among elderly individuals.

Introduction Advancements in our understanding of vestibular physiology and how it is changes in different diseases have established that of the three therapeutic approaches to treat disorders of the vestibular system viz. pharmacotherapy, surgery and physical therapy, it is the later i.e., physical therapy which is the most efficacious modality in the management of balance disorders. The futility of vestibular sedatives in the correction of vestibular disorders and in the restoration of balance and the very limited role of surgery has now been recognised. Advancements in vestibulometry now enable us to localise any lesion in the vestibular system with utmost precision and also determine the exact cause of the balance disorder. The site of lesion and the specific organ that is defective can now be very precisely identified. Treatment modalities especially that for physical therapy hence have to be organ specific, and if possible, also disease specific. Aims and Objectives The study aims at evaluating the efficacy of physiotherapy in the management of balance disorders and also assesses the efficacy of organ targeted physical therapy, a new concept in restoring balance after vestibulometry has identified the offending organ. Materials and Methods The study was conducted in the specialised physical therapy unit for balance and gait disorder patients which is a part of Vertigo and Deafness Clinic in Kolkata, India. Special instruments for physical therapy devised by the first author were used for stimulation of specific sense organs in the vestibular labyrinth that were found to be defective in vestibulometry. Specially made Virtual reality programs were used in patients suffering from psychogenic balance disorders. The pre and post therapy status was evaluated by different standard scales to assess balance and dizziness. Results Very promising results were obtained. Organ targeted physiotherapy where defective sense organs were specifically stimulated showed remarkable improvement in different measures. Virtual reality exercises too showed very promising results in patients of psychogenic vertigo.

“…As to caloric testing, the stimuli are unphysiological and the technique is still somewhat uncomfortable to the patient, and is also timeconsuming (average 10 min); in addition, it can't be performed for patients with eardrum perforation [1][2][3]. As far as HSN test is concerned, it can't be performed in patients with neck injury [4,[20][21][22].…”

This study was done to clarify the clinical significance of vibration-induced nystagmus (VIN) and to calculate the sensitivity and the specificity of the vibration test. One hundred and twelve patients with unilateral peripheral vestibular disorders and thirty normal subjects were enrolled into this study. However, patients with spontaneous nystagmus were excluded. Vibration stimuli (approximately 100 Hz) were presented to the mastoids and the forehead. Patients and normal subjects also underwent head shaking nystagmus (HSN) test and caloric testing. Among the 112 patients, 91(81 %) showed VIN which were mainly horizontal. VIN was more frequently elicited on the mastoids than on the forehead. In the majority of patients (76 cases), the direction of VIN was toward the healthy side, whereas patients with Meniere's disease (15 cases), showed nystagmus toward the affected side. None of 30 normal subjects showed VIN. Whereas HSN was found in 70 (63 %) patients and 9 (30 %) in normal subjects. Among 112 patients, 10 showed a canal paresis (CP) value of caloric testing less than 25 %, while 32 with a CP value between 25 and 40 %, 48 with a CP value between 40 and 70 %, and 22 with a CP value no less than 70 %. It is notable that with increasing CP value on caloric testing, VIN was more likely to be elicited. So VIN test is a simple, non-invasive and well-tolerated clinical test that indicates unilateral peripheral vestibular dysfunction. VIN test had greater sensitivity and specificity than HSN test in the diagnosis of unilateral peripheral vestibular disorders.
