Medical evaluation was performed on a group of paraplegics who were trained to walk with the Reciprocating Gait Orthosis powered with electrical muscle stimulation (RGO II). The evaluation included changes in spasticity, cholesterol level, bone metabolism, cardiac output and stroke volume, vital capacity, knee extensors torque, and heart rate at the end of a 30-meter walk. After an average of 14 weeks of training during which patients walked for 3 hours per week, significant reductions in spasticity, total cholesterol and low-density lipids, hydroxyproline/creatinine ratio, and increased knee extensor torque were evident. The data also showed that improvements occurred in the calcium/creatinine ratio, serum calcium and alkaline phosphatase levels, cardiac output and stroke volume, and vital capacity, yet these improvements were not statistically significant. The final heart rate at the end of a 30-meter walk showed that the RGO II required only a moderate level of exertion, which was found to be the lowest among the other mechanical or muscle stimulation orthoses available to paraplegics. It was concluded that the limited but reasonable level of functional regain provided by the RGO II is associated with a general improvement in the paraplegic's physiological condition if used for a minimum of 3 to 4 hours per week.

Immobilisation secondary to spinal cord injury (SCI) is associated with marked and rapid atrophy of trabecular bone. The purpose of this study was to evaluate bone mineral density (BMD) in both the upper and lower extremities following SCI sustained for various lengths of time and to correlate the BMD to the level of the lesion, time from injury, spasticity and serum calcium, phosphorus and alkaline phosphatase (ALP) levels. A study was undertaken in 41 SCI patients with a mean age of 35.8 +/- 12.7 years. A significant difference in BMD between upper and lower extremities of the paraplegics were found. BMD of upper and lower extremities were similar in tetraplegies. The BMD values were significantly different when the upper extremity scores of paraplegics and tetraplegics were compared but BMD scores of the lower extremities were similar in the two groups. The decrease in BMD was less in the spastic patients when compared to the flaccid group. There was a positive correlation between time from injury and the degree of BMD deficit in the paralysed areas. In the whole group of patients a significant positive correlation was found between the duration of SCI and serum ALP levels.

Heterotopic ossification (HO) is an important complication of spinal cord and brain injuries but is rarely reported among patients with non-traumatic myelopathies. In a prospective study on medical problems seven (6.04%) among the 114 subjects with non-traumatic myelopathies had heterotopic ossification. All of them had involvement of hip joints. The co-morbid conditions were: urinary tract infection, seven; spasticity, three; pressure sores, five; and deep venous thrombosis, one. The initial diagnosis was often other than heterotopic ossification. Erythrocyte sedimentation rate and serum alkaline phosphatase levels were elevated in all subjects. Following rest and non-steroidal anti-inflammatory drugs, the range of motion improved in two patients. Heterotopic ossification can occur in patients with non-traumatic myelopathies and has risk factors and clinical features similar to patients with traumatic spinal cord injury. A high index of suspicion about this complication is necessary for early diagnosis and prompt intervention.

Heterotopic ossification, or myositis ossificans, denotes true bone in an abnormal place. The pathogenic mechanism is still unclear. A total of 643 patients (mean age, 9.1 years) admitted for neuropediatric rehabilitation were analyzed retrospectively with respect to the existence of neurogenic heterotopic ossification. The purpose of this study was to obtain information about incidence, etiology, clinical aspect, and consequences for diagnosis and therapy of this condition in childhood and adolescence. Heterotopic ossification was diagnosed in 32 patients (mean age, 14.8 years) with average time of onset of 4 months after traumatic brain injury, near drowning, strangulation, cerebral hemorrhage, hydrocephalus, or spinal cord injury. The sex ratio was not significant. In contrast to what has been found in adult studies, serum alkaline phosphatase was not elevated during heterotopic ossification formation. A persistent vegetative state for longer than 30 days proved to be a significant risk factor for heterotopic ossification. The incidence of neurogenic heterotopic ossification in children seems to be lower than in adults. A genetic predisposition to heterotopic ossification is suspected but not proven. As a prophylactic regimen against heterotopic ossification we use salicylates for those patients in a coma or persistent vegetative state with warm and painful swelling of a joint and consider continuous intrathecal baclofen infusion and botulinum toxin injection for those patients with severe spasticity. We prefer to wait at least 1 year after trauma before excision of heterotopic ossification.

Heterotopic ossification (HO) is an important cause of restriction in range of movements and secondary motor disability following neurotrauma, orthopaedic interventions and burns. It has not received focussed attention in non-traumatic neurological disorders. In a prospective study of 377 patients, on medical problems in neurological rehabilitation setting, 15 subjects (3.97%) had neurogenic heterotopic ossification. Their clinical diagnosis was: transverse myelitis (7), neurotuberculosis (4), traumatic myelopathy (2) and stroke (2). Hip (10), knee (4) and elbow joints (1) were involved. The risk factors included urinary tract infection (15), spasticity (6), pressure sores (13) and deep venous thrombosis (DVT) (6). The initial diagnosis was often other than HO and included DVT (3), haematoma (2) and arthritis (2). ESR and serum alkaline phosphatase levels were elevated in all but one subject. The diagnosis of HO was established using X-rays, CT Scan and three-phase bone scan. Following treatment with non-steroidal anti-inflammatory drugs, the range of motion improved in only four patients. HO resulted in significant loss of therapy time during rehabilitation. High index of suspicion about this complication is necessary for early diagnosis and prompt intervention.
