[Nerve transfer in patients with tetraplegia: improvement in hand function]. / Zenuwtransfer bij patiënten met een tetraplegie.

Reconstruction of arm and hand function in patients with a cervical spinal cord injury can improve their quality of life. Elbow extension, wrist extension, grip function and opening of the hand can be reconstructed. Traditionally, this has been done through tendon transpositions. Nerve transfer is a new technique. A functioning motor nerve branch is moved and connected to a muscle or muscle group damaged by the spinal cord injury. This technique has several advantages. Multiple functions can be restored by one nerve transfer, no long-term hand-rehabilitation is required and there is no risk of adhesions of the transposition. The most important disadvantage is the recovery time, as a results of the slow ingrowth of the nerve transfer, which takes at least 12 to 18 months. For each spinal cord injury patient, an individual action plan must be made, because not every patient has the same options and these are sometimes very limited.

Performance and Self-reported Functioning of People With Chronic Idiopathic Axonal Polyneuropathy: A 4-Year Follow-up Study.

OBJECTIVE: To describe the course of performance of activities (observed and self-reported) of people with chronic idiopathic axonal polyneuropathy (CIAP) over 4 years and to assess the associations with muscle strength, sensory function, and psychological personal factors (intention, perceived behavior control [PBC], and feelings of depression or anxiety). DESIGN: Prospective observational study with measurement at baseline, 6 months, 1 year, and 4 years. SETTING: Outpatient neurology clinic. PARTICIPANTS: People with CIAP (N=92). MAIN OUTCOME MEASURES: Walking was measured using the shuttle-walk test (SWT), a pedometer (mean step count/d), and the "physical functioning" subscale of the Short Form-36 questionnaire. Muscle strength and sensory function were measured using a MicroFET handheld dynamometer and the Sensory Modality Sum score. Personal factors were assessed with the Hospital Anxiety and Depression Scale, and intention and PBC were assessed with a protocolized questionnaire. RESULTS: Multilevel model analysis showed a significant decrease over time in mean scores in performance of activities (SWT, step count), which was associated with older age and loss of muscle strength (SWT: ß=73.392, step count: ß=676.279, P<.001). Limitations in self-reported functioning (physical functioning) significantly increased and were associated with older age (ß=-0.916, P=.001), increased comorbidity (ß=-6.978, P=.024), loss of muscle strength (ß=7.074, P<.001), low PBC (ß=0.744, P<.001), and increased feelings of depression (ß=1.481, P<.001). CONCLUSIONS: Performance of activities of people with CIAP decreased over time (SWT, step count, physical functioning). Older age, loss of muscle strength, comorbidity, feelings of depression, and low perceived behavior control were associated with this decrease. However, there were considerable individual differences.
