简要总结
This study is to investigate the effects of task-based biofeedback training compared with home-based programs on sensorimotor function and quality of life for diabetic patients with neuropathic hands. The investigators hypothesize that the task-based biofeedback training might have significant effectiveness for restoration of sensory function, precision pinch performance, hand dexterity and life quality for patients with diabetic neuropathy.
详细描述
Hand tendon gliding exercises allow both the flexor digitorum profundus and superficialis tendons of hands to achieve the greatest range of motion. Thus, in conjunction with resistive exercises for diabetic hands, such exercises are considered an appropriate home-based training method that has positive effects on various diabetic hand problems in terms of regaining smooth tendon excursion, preventing joint contracture, and reducing intrinsic muscle tightness. Different from the biomechanical approach to deal with hand problems, a biofeedback system can be used to provide real-time information on improper movements during task-based training intended to enhance either performance quality or accuracy. This study aims to analyze the difference in treatment effects between a computerized evaluation and a re-education biofeedback system that provides interactive sensorimotor information to shape the optimized coordinated pinch pattern of a hand and a home-based tendon gliding exercise program in conjunction with resistive exercise with weekly supervision on sensorimotor function and quality of life for diabetic patients. The investigators hypothesize the task-based biofeedback training using the biofeedback training system could have significant effectiveness for restoration of sensory function, precision pinch performance, hand dexterity and life quality for patients with diabetic neuropathy.

结局指标
主要结局
Static two-point discrimination (S2PD) test
时间窗: 6~8 weeks after intervention
The two-point discrimination test which is used to detect the shortest distance between the points that the subjects can perceive are tools for tactile acuity measuring.
Moving two-point discrimination (M2PD) test
时间窗: 6~8 weeks after intervention
The Moving two-point discrimination test which is used to detect the shortest distance between the points that the subjects can perceive are tools for tactile acuity measuring. Also,it measures the innervation density of slowly and quickly adapting nerve fibers, respectively, and their corresponding mechanoreceptors as well.
Michigan Hand Outcomes Questionnaire (MHQ)
时间窗: 6~8 weeks after intervention
Michigan Hand Outcomes Questionnaire (MHQ), a hand-specific outcomes instrument, is sensitive to providing an understanding of clinical changes with patients' self-reports. The MHQ contains six dimensions with 37 hand-specific questions. Higher scores indicate better hand function, with the exception of the pain facet. The testing reliability of MHQ ranges from 0.81 to 0.97.
Purdue Pegboard test
时间窗: 6~8 weeks after intervention
The Purdue Pegboard test has high testing validity and reliability and has been broadly used to measure hand dexterity. The test comprises four subtests involving the ability of the subject to place pins in small holes with the dominant hand, non-dominant hand, and with both hands simultaneously, as well as performing an assembly task.
Diabetes-39 (D-39)
时间窗: 6~8 weeks after intervention
The Diabetes 39 (D-39) is a disease-specific questionnaire used to assess quality of life (QoL) in patients with diabetes. It contains of 39 questions regarding five dimensions, including energy and mobility, diabetes control, anxiety and worry, social and peer burden, and sexual functioning. Higher scores on all dimensions reveal a better QoL. The reliability of the Chinese version of the tool ranges from 0.82 to 0.93, and it also has good convergent and discriminant validity.
Semmes-Weinstein monofilament (SWM)
时间窗: 6~8 weeks after intervention
A touch-pressure threshold test with 20 nylon filaments with varying degrees of thickness is conducted. The examiner presses the filament at a 90° angle against the skin until it bows. When the patient indicates a response, the result is recorded. The filament is labeled with a numerical marking, which is a log to the base ten of the force in tenths of a milligram. The threshold value is the finest filament to which the subject correctly responds.
The pinch-holding-up activity (PHUA) test
时间窗: 6~8 weeks after intervention
For the PHUA test, the participants were asked to pinch and lift the pinch device, and the pinch force will be recorded during the task. The raw force value would be collected and transferred into specific parameters include: (1) FP\_Peak: the maximum pinch force during the lifting phase in the PHUA test; (2) FL\_Max: the maximum load force at the onset of maximum upward acceleration; (3) force ratio of FP\_Peak to FL\_Max; (4) percentage of maximal pinch strength: the FP\_Peak divided by the maximal static pinch strength as a percentage of maximum voluntary contraction are detected in the initial evaluation.
