Brief summary
The aim of this study is to determine the comparative effects of intraneural facilitation therapy and nerve flossing technique on pain, balance, gait, and quality of life in Diabetic peripheral neuropathy.
Detailed description
Intraneural Facilitation Therapy is a novel manual therapy technique that seeks to enhance endoneurial capillary circulation, bias blood flow into the neural fascicle, and reverse intrafascicular ischemia. To redirect blood to the ischemic nerves, this passive approach involves tractioning skin, distending visceral tissues, stretching muscles, mobilizing joints, and stretching blood vessels. The Nerve Flossing Technique is an emerging treatment approach that aims to improve neurodynamic, range of motion, and quality of life. Intraneural Facilitation and Nerve Flossing Techniques address diabetic peripheral neuropathy, and their effectiveness in improving pain, balance, gait, and quality of life remains un-compared. This randomized clinical trial will be conducted at Social Security Hospital, and Siddique Family Hospital, Gujranwala. 44 Participants who meet the inclusion criteria will be selected through a non-probability convenience sampling technique and randomly allocated into two groups using an online randomizer tool. Participants will be included in Groups A (Intraneural Facilitation Therapy) and Group B (Nerve Flossing Technique). A total of 24 sessions (3x/week for 8 weeks) will be conducted, lasting 60 minutes each.. A Numeric Pain Rating scale will be used to assess pain, the Berg Balance Scale (BBS) to assess balance, a 4-item Dynamic Gait Index to assess Gait, and the Quality of Life-Diabetic Neuropathy (QOL-DN) for quality of life. Assessment will be carried out at baseline (before treatment), after the 8th week (post-intervention), and at a 2-month follow-up. The data will be entered and analyzed using the IBM SPSS Statistics 27.0 version. Statistical significance will be set at p ≤0.05.
Interventions
* The initial hold, known as the facilitation hold, involves placing the contralateral joint in a maximal loose-pack position that will be comfortable for the patient. An illustration of this would be positioning the ankle joint on the contralateral side in full plantar flexion and inversion. Throughout the entire session, this position will be maintained using a stretch strap. It is crucial to emphasize that there is no muscle engagement in the joint where the facilitation takes place, only a slight stretch. * Once the pressure elevation occurs, the subsequent phase known as the secondary hold will be initiated to direct the augmented flow of epineurial blood toward the transperineurial vessels connecting the epiperineum and the endoneurial capillaries of the target area. * The final maneuver, the sub hold, leverages Bernoulli's principle to augment blood flow through the ischemic endoneurial capillaries experiencing heightened transmural pressure.
Tibial Nerve: 1. Passively flex the hip while dorsiflexing and everting the ankle to create tension; flex the knee to unload, then extend and plantarflex to reload. 2. Flex the hip, extend the knee, and dorsiflex and evert the ankle to induce tension; flex the hip to unload, then extend and plantarflex to reload. 3. Lift the leg, flex the hip, and extend the knee; dorsiflex and evert the ankle to induce tension, then plantarflex to unload. Common Peroneal Nerve: 1. Passively flex the hip and plantarflex and invert the ankle to induce tension; flex the knee to unload, then extend and dorsiflex to reload. 2. Flex the hip, extend the knee, and plantarflex and invert the ankle to induce tension; flex the hip to unload, then extend and dorsiflex to reload. 3. Lift the leg, flex the hip, and extend the knee; plantarflex and invert the ankle to induce tension, then dorsiflex to unload.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Numeric Pain Rating Scale | 8 week | Numeric Pain Rating Scale is a subjective measure 11 point (0-10) numerical scale which is a commonly used outcome measure to assess pain intensity, including in patients with diabetic peripheral neuropathy. Its score ranges from 0 indicating no pain at all to 10 indicating worst pain. In NPRS, 0 for No pain, 1-3 range for Mild pain, 4-6 range for Moderate pain, and 7-10 indicates Severe pain. |
| Michigan Neuropathy Screening Instrument | 8 week | Michigan Neuropathy Screening Instrument (MNSI) is a simple, non-invasive, and valid tool for screening DPN in diabetic patients. The initial section of the assessment tool comprises a self-administered questionnaire (15 yes-or-no questions) focusing on foot sensation, including aspects like discomfort, numbness, and temperature sensitivity. The subsequent segment involves a brief physical examination such as visual inspection of the feet, testing ankle reflexes using a tendon hammer, assessing vibration perception utilizing a 128 Hz tuning fork, and evaluating tactile sensation through the application of a 10 gm Semmes-Weinstein Monofilament (SWM). A score greater than 3 on the MNSI-Q and greater than 2 on the MNSI-PE suggests diabetic peripheral neuropathy. |
| Quality of Life- Diabetic Neuropathy Questionnaire | 8 week | The Norfolk QOL-DN is an extensive and validated 47-item questionnaire that has been developed to encompass the complete range of Diabetic Neuropathy (DN) symptoms associated with small fiber, large fiber, and autonomic neuropathy. It is composed of two sections: one focusing on the symptoms experienced by diabetic patients and the other on how the patient's neuropathy affects their activities of daily living (ADLs). The questionnaire items are divided into six different domains, namely overall quality of life, symptoms, ADLs, physical functioning/large fiber, small fiber, and autonomic neuropathy. The symptom domain (items 1-7) will allocated a score of 1 or 0, denoting the presence or absence of the specified symptoms. Apart from items 31 and 32, the remaining items were evaluated using a 5-point scale (0-4, ranging from No Problem to Severe Problem).A score range of 2-9 classified the neuropathy as mild, 10-19 as moderate, and greater than or equal to 20 as severe. |
| BERG BALANCE SCALE | 8 week | The BBS is a postural balance scale containing 14 items including standing and sitting unsupported, reaching forward, and placing the alternating foot on a stool. Administering the BBS takes approximately 15 min. Each of the 14 items is scored on a 5-level ordinal scale from 0 (unable to perform or requiring help) to 4 (normal performance), thus providing a potential maximum score of 56 points. |
| 4-Item Dynamic Gait Index | 8 week | It is a shortened version of the Dynamic gait index. It consists of 4 items of Dynamic gait index such as horizontal head turns, vertical head turns, gait on level surfaces, and changes in gait speed. Each of the four items is scored on an ordinal scale from 0-3 with higher numbers indicating better performance of the specified task. Additionally, each item has specific criteria that must be met to be granted a specific score number. The test has a total score of 12. |
