Assessments and Interventions for Hand Neuropathy in DM
February 18, 2019 updated by: National Cheng-Kung University Hospital
Functional Measurements and Therapeutic Intervention for Hand Neuropathy in Diabetes Mellitus
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.

Detailed Description
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.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Biofeedback training group
The participants in the biofeedback training group attend a 30 minute biofeedback protocol per session, two times a week for six to eight weeks that is also combined with the regular diabetic care treatment in the Occupational Therapy Room.
|
Before the biofeedback training, the baseline pinch force detected from a pinch-holding-up activity is recorded to set the target level according to the baseline data.
With the aim for improving the performance, a 94% peak force value detected at the baseline is set as the target threshold for the training.
Each participant attends a 30-minute biofeedback protocol per session, two times a week for six to eight weeks.
Once the pinch force value exceeds the target range, visual and auditory cues are provided to inform the subjects to modify the performance.
|
Active Comparator: Home-based training group
The participants in this group receive similar doses of home-based tendon gliding exercises and resistance training with an anti-stress ball for 30 minutes at a frequency of 2 times a week for 6 to 8 weeks, also combined with the regular diabetic care treatment.

Six to eight telephone visits are carried out to remind the patients to comply with the exercise program during the training period.

No Intervention: Control group
The participants in the control group receive only diabetes disease prevention consultation once and outcome assessments twice.

Time Frame |
---|---|---|
The pinch-holding-up activity (PHUA) test
Time Frame: Baseline
|
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.

The pinch-holding-up activity (PHUA) test
Time Frame: 6~8 weeks after intervention

Semmes-Weinstein monofilament (SWM)
Time Frame: Baseline
|
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.

Purdue Pegboard test
Time Frame: Baseline
|
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.
