Efficacy of a Structured Multisensory Re-education Program on Sensory Function and Upper Limb Sensorimotor Performance in Individuals With Diabetic Peripheral Neuropathy. (SENS-UL)

25 giugno 2026 aggiornato da: Turki Abualait, Imam Abdulrahman Al Faisal Hospital

Efficacy of a Structured Multisensory Re-education Program on Sensory Function and Upper Limb Sensorimotor Performance in Individuals With Diabetic Peripheral Neuropathy: A Randomized Sham-Controlled Trial.

Diabetic Peripheral Neuropathy (DPN) is a common complication of diabetes that can cause impairments in sensation, dexterity, and upper-limb function. Current treatment approaches mainly focus on symptom management and glycemic control, while interventions specifically targeting sensory recovery remain limited.

This randomized sham-controlled trial aims to evaluate the effectiveness of a Structured Multisensory Re-education Program (SENS-UL) in improving sensory function and upper-limb sensorimotor performance in adults with DPN. Participants will be randomly assigned to either an intervention group receiving structured multisensory sensory re-education or a sham-control group receiving passive sensory exposure without active sensory retraining.

The intervention will be delivered twice weekly for five weeks. Outcome measures will include sensory function, neuropathy severity, thermal and tactile sensation, vibration perception, proprioception, dexterity, and neuropathy-related quality of life. Assessments will be conducted before and after the intervention period.

The study is expected to provide evidence regarding the effectiveness of multisensory sensory rehabilitation for individuals with DPN and may contribute to the development of targeted rehabilitation strategies aimed at improving sensory recovery, hand function, and quality of life.

Descrizione dettagliata

Diabetic Peripheral Neuropathy (DPN) is one of the most common chronic complications of diabetes mellitus and is associated with sensory loss, impaired sensorimotor performance, reduced functional independence, and decreased quality of life. Although DPN is commonly associated with lower-limb dysfunction, upper-limb sensory impairments may also occur and negatively affect hand function, dexterity, object manipulation, and activities of daily living.

Current management strategies primarily focus on glycemic control, pharmacological symptom management, and general exercise interventions. However, rehabilitation approaches specifically designed to improve sensory function remain limited. Evidence from neurorehabilitation research suggests that sensory re-education interventions may promote neuroplasticity, improve sensory discrimination, enhance cortical sensory processing, and improve functional outcomes.

This study will investigate the efficacy of a Structured Multisensory Re-education Program (SENS-UL Protocol) in adults with clinically confirmed Diabetic Peripheral Neuropathy. The study will use a prospective, parallel-group, participant-blinded, randomized sham-controlled design.

Participants will be recruited from King Fahad Medical City, Riyadh, Saudi Arabia. Eligible participants will be randomly allocated to either an experimental group receiving structured multisensory sensory re-education or a sham-control group receiving passive sensory exposure without active sensory retraining. The intervention will be delivered twice weekly for five weeks, with each session lasting approximately 50-60 minutes.

The intervention includes tactile stimulation, texture discrimination, vibration stimulation, thermal discrimination, localization training, joint position sense training, kinesthesia training, two-point discrimination, stereognosis, barognosis, graphesthesia, and double simultaneous stimulation. The program follows a standardized hierarchical progression model with predefined progression criteria.

Primary outcomes include sensory function performance, Modified Total Neuropathy Score (mTNS), thermal sensory thresholds, Semmes-Weinstein Monofilament Test, vibration perception threshold, joint position sense, two-point discrimination, and neuropathy-related quality of life. Secondary outcomes include Nine-Hole Peg Test and Grooved Pegboard Test performance.

The findings of this study are expected to provide evidence regarding the role of multisensory sensory rehabilitation in improving sensory recovery and upper-limb function in individuals with Diabetic Peripheral Neuropathy.

Cosa sta misurando lo studio?

Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Composite Sensory Function Score Measured Using Quantitative Sensory Testing (QST)
Lasso di tempo: Baseline and Post-intervention (5 Weeks)
Composite sensory function will be assessed using Quantitative Sensory Testing (QST) comprising the Semmes-Weinstein Monofilament Test (SWMT; monofilament level), Vibration Perception Threshold (VPT; Hz), Cold Detection Threshold (°C), Warm Detection Threshold (°C), Joint Position Sense (degrees of reposition error), and Two-Point Discrimination (mm). A standardized composite sensory function score will be calculated from these measures. Higher composite scores indicate better sensory function.
Baseline and Post-intervention (5 Weeks)

Misure di risultato secondarie

Misura Descrizione
Lasso di tempo
Neuropathy Severity Measured by the Modified Total Neuropathy Score (mTNS)
Lasso di tempo: Baseline and Post-intervention (5 Weeks)
Neuropathy severity will be assessed using the Modified Total Neuropathy Score (mTNS). The mTNS evaluates sensory symptoms, motor symptoms, pin sensibility, vibration sensibility, muscle strength, and deep tendon reflexes. The outcome measure will be the total mTNS score (points; range 0-24), with lower scores indicating less severe neuropathy.
Baseline and Post-intervention (5 Weeks)
Upper Limb Dexterity Measured by the Nine-Hole Peg Test (9HPT)
Lasso di tempo: Baseline and Post-intervention (5 Weeks)
Upper limb dexterity will be assessed using the Nine-Hole Peg Test (9HPT). The outcome measure will be completion time (seconds). Lower times indicate better hand dexterity.and fine motor performance.
