Impact of health problems secondary to SCI one and five years after first inpatient rehabilitation.

STUDY DESIGN: This is a multicenter prospective cohort study. OBJECTIVES: The objective of this study was to describe and compare the impact of health problems secondary to spinal cord injury (SCI) on functioning at home and on social activities at 1 and 5 years after discharge from first inpatient rehabilitation. SETTING: The study was conducted in a Dutch community. METHODS: Participants with SCI who use a wheelchair for everyday mobility (N=110) completed a self-report questionnaire as part of a larger cohort study including four items on extra time needed (body care, bladder and bowel regulation, 'organization' and transportation) and impact of 10 health problems on functioning at home and on social activities. The 10 health problems include secondary health conditions (bladder regulation, bowel regulation, decubitus, pain, spasticity, gain in body weight and edema), psychosocial problems (sexuality, having difficulty with being dependent on help from others) and handicap management. RESULTS: Median extra time needed for self-management and transportation was not significantly higher 1 year after discharge (16 (IQR 13.5) h per week) compared with 5 years after discharge (13 (IQR 17) h per week) (P=0.925). Participants reported slightly less impact, comparing the severity sum-score (range 10-50) of the 10 health problems on functioning at home and in social activities, 5 years post discharge (20 and 17, respectively) than 1 year post discharge (21 and 18, respectively; P<0.05). Most frequently mentioned health problems were handicap management, being dependent on help from others, bladder regulation, bowel regulation, pain and sexuality. CONCLUSIONS: The impact of health problems after SCI is considerable and hardly diminishes over time. These results emphasize the need for structured long-term care for people with SCI.

Electromechanical abdominal massage and colonic function in individuals with a spinal cord injury and chronic bowel problems.

STUDY DESIGN: A prospective intervention of noninvasive abdominal massage using an electromechanical apparatus on bowel function in individuals with spinal cord injury (SCI). OBJECTIVES: To evaluate the effects of noninvasive abdominal massage using an electromechanical apparatus on bowel function in individuals with SCI and chronic bowel problems. This easy-to-use apparatus can be applied by the patients at home without the help of a therapist. SETTING: Homes of community-living individuals. METHODS: Twenty-one subjects with SCI were instructed to use the massage apparatus daily for 20 min during a 10-week period. Compliance, effects, side effects and user satisfaction were assessed using questionnaires. RESULTS: Fifteen subjects completed the 10-week period. Although some characteristics of defecation changed positively for some of the subjects (time to result, amount, consistency), none felt better or more confident after using the massage device. In addition, some individuals experienced negative side effects (predominantly pain or discomfort). The overall satisfaction with the device is ambiguous, with half of the group judging the device as insufficient and the other half as at least adequate. CONCLUSION: The use of an electromechanical massage device does not improve bowel function in most individuals with SCI who have chronic bowel problems. Why some subjects benefit and others do not should be investigated in future studies.

Gluteal blood flow and oxygenation during electrical stimulation-induced muscle activation versus pressure relief movements in wheelchair users with a spinal cord injury.

BACKGROUND: Prolonged high ischial tuberosities pressure (IT pressure), decreased regional blood flow (BF) and oxygenation (%SO2) are risk factors for developing pressure ulcers (PUs) in patients with spinal cord injury (SCI). Electrical stimulation (ES)-induced gluteal and hamstring muscle activation may improve pressure distribution by changing the shape of the buttocks while sitting and also increase BF and %SO2. OBJECTIVE: To compare acute effects of ES-induced gluteal and hamstring muscle activation with pressure relief movements (PRMs) on IT pressure, BF and %SO2. PARTICIPANTS AND METHODS: Twelve men with SCI performed PRMs - push-ups, bending forward and leaning sideward - and received surface ES (87±19 mA) to the gluteal and hamstring muscles while sitting in their wheelchair. Ischial tuberosities pressure was measured using a pressure mapping system; (sub)cutaneous BF and %SO2 were measured using reflection spectroscopy and laser Doppler, respectively. RESULTS: Compared with rest (156±26 mm Hg), IT pressure was significantly lower during all other conditions (push-ups 19±44; bending forward 56±33; leaning sideward 44±38; ES 67±45 mm Hg). For the whole group, all PRMs significantly augmented BF (+39 to -96%) and %SO2 (+6.0 to -7.9%-point), whereas ES-induced muscle activation did only for peak BF. In all, 63% of the participants showed an increased BF (average 52%) with ES. CONCLUSION: PRMs acutely reduced IT pressure and improved oxygenation and BF in SCI. The currently used ES method cannot replace PRMs, but it may be used additionally. ES-induced muscle activation is not as effective for acute pressure relief, but the frequency of stimulation is much higher than the performance of PRMs and can therefore be more effective in the long term.

Effects of electrical stimulation-induced gluteal versus gluteal and hamstring muscles activation on sitting pressure distribution in persons with a spinal cord injury.

STUDY DESIGN: Ten participants underwent two electrical stimulation (ES) protocols applied using a custom-made electrode garment with built-in electrodes. Interface pressure was measured using a force-sensitive area. In one protocol, both the gluteal and hamstring (g+h) muscles were activated, in the other gluteal (g) muscles only. OBJECTIVES: To study and compare the effects of electrically induced activation of g+h muscles versus g muscles only on sitting pressure distribution in individuals with a spinal cord injury (SCI). SETTING: Ischial tuberosities interface pressure (ITs pressure) and pressure gradient. RESULTS: In all participants, both protocols of g and g+h ES-induced activation caused a significant decrease in IT pressure. IT pressure after g+h muscles activation was reduced significantly by 34.5% compared with rest pressure, whereas a significant reduction of 10.2% after activation of g muscles only was found. Pressure gradient reduced significantly only after stimulation of g+h muscles (49.3%). g+h muscles activation showed a decrease in pressure relief (Δ IT) over time compared with g muscles only. CONCLUSION: Both protocols of surface ES-induced of g and g+h activation gave pressure relief from the ITs. Activation of both g+h muscles in SCI resulted in better IT pressure reduction in sitting individuals with a SCI than activation of g muscles only. ES might be a promising method in preventing pressure ulcers (PUs) on the ITs in people with SCI. Further research needs to show which pressure reduction is sufficient in preventing PUs.

Evaluation of the physical activity scale for individuals with physical disabilities in people with spinal cord injury.

STUDY DESIGN: Cross-sectional study. OBJECTIVES: To evaluate the physical activity scale for individuals with physical disabilities (PASIPD) in people with spinal cord injury (SCI). SETTING: Eight Dutch rehabilitation centers with a specialized SCI unit. METHODS: The PASIPD was examined by comparing group scores of people with different personal (age, gender and body mass index) and lesion characteristics (level (paraplegia/tetraplegia), completeness, time since injury (TSI)) in 139 persons with SCI 1 year after discharge from in-patient rehabilitation. Relationships between PASIPD scores and measures of activities (wheelchair skills, Utrecht Activity List, mobility range and social behavior subscales of the SIP68) and fitness (peak oxygen uptake, peak power output and muscular strength) were determined. RESULTS: Persons with tetraplegia had significantly lower PASIPD scores than those with paraplegia (P<0.02). Persons with longer TSI had lower PASIPD scores than persons with shorter TSI (P<0.03). PASIPD scores showed moderate correlations with activities (0.36-0.51, P<0.01) and weak-to-moderate correlations with fitness parameters (0.25-0.36, P<0.05). CONCLUSION: In a fairly homogeneous group of persons with SCI, 1 year after in-patient rehabilitation, the PASIPD showed weak-to-moderate relationships with activity and fitness parameters. There seems to be a limited association between self-reported activity level and fitness in people with SCI.

Heart conduction problems in a tetraplegic patient caused by a single therapeutic dosage of Baclofen.

STUDY DESIGN: Case report. OBJECTIVE: To examine the unusual and unknown, severe side effect of a therapeutic dose of oral Baclofen on cardiac function. SETTING: Spinal Cord Unit, Rehabilitation Centre Amsterdam, Amsterdam, The Netherlands. METHODS: Review of relevant literature. RESULTS: A 53-year-old patient with an incomplete C2 tetrapareses (ASIA B) developed severe and painful muscle spasms together with respiratory failure and autonomic dysreflexia. Spasmolytic treatment was started. After the first admission of 5 mg of oral Baclofen, he collapsed in bed with extreme bradycardia, hypotension, hyperventilation and decreased oxygen saturation. A second dosage of 5 mg Baclofen resulted in the same complications. After implantation of a pacemaker, restarting oral Baclofen induced a pacemaker rhythm with episode of hypotension and respiratory failure and also a delirium. Intrathecal Baclofen also resulted in a pacemaker rhythm with hypotension and a decreased cardiac output. To our knowledge, this is the first time a severe heart conduction problem was induced in a spinal cord injury patient after a single therapeutic dose of Baclofen. CONCLUSION: In this case therapeutic oral Baclofen has caused serious cardiac conduction problems.
