Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The main objective of this trial is to investigate the effect of a customized foot-related exercises software (SOPeD) in diabetic neuropathy status, functional outcomes and gait biomechanics in people with diabetic neuropathy.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

A randomized controlled trial will be performed with 62 patients with diabetic neuropathy. The participants will be randomly assigned into either a control group (recommended foot care by international consensus with no foot exercises) or an intervention group that will perform exercises at home, three times a week, through the SOPeD (Diabetic Foot Guidance System) software for 12-weeks. The exercise program is customized during the performance by a perceived effort scale reported by the participant.

The subjects will be evaluated in 3 different times to access the effect of the intervention: baseline and 12 weeks, for all outcomes; and 24 weeks, for follow-up reasons for all outcomes. The following outcomes will be assessed in all times: (1) diabetic neuropathy symptoms and signs by Michigan Neuropathy Screening Instrument, (2) fuzzy score of the neuropathy severity, (3) foot-ankle kinematics during gait (infrared cameras) (4) foot-ankle joint moment during gait (infrared cameras and force plate), (5) plantar pressure distribution during gait, (6) tactile (monofilaments), (7) vibration sensitivity (tuning fork), (8) foot health and functionality by the Foot Health Status Questionnaire, (9) Foot isometric strength (pressure plate measurement), (10) functional balance reach test.

The hypothesis of this study is that the intervention will increase the perception of the tactile and vibratory sensitivity of the foot, reduce the symptoms of diabetic neuropathy, increase the strength of the foot muscles, increase the functional balance score, decrease the severity of the diabetic neuropathy (fuzzy score), decrease the number of neuropathy symptoms, promote a more physiological foot rollover with a redistribution of plantar pressure during gait, as well as increase foot-ankle mobility after 12-weeks of intervention. There will be also beneficial biomechanical changes during gait, such as: (1) increase in the ankle extensor moment and ankle concentric power in the propulsion phase and (3) increase in the ankle flexor moment and ankle eccentric power in the load phase.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Intervention Group

Patients in the intervention group will perform foot-related exercises described in the SOPeD software three times/week at home via web-software. In the follow-up period, patients will follow the same schedule set by the project till the end of the study.

Group Type EXPERIMENTAL

Physical therapy by foot-ankle segmental and functional exercises

Intervention Type OTHER

The physiotherapeutic foot-ankle exercise protocol is based on previous clinical trials. It was designed following three criteria established in a supervised, face-to-face intervention: muscle stretching; strengthening of the intrinsic muscles; and strengthening of the extrinsic foot-ankle muscles and functional exercises, such as balance and gait training. To avoid monotony, game principles were inserted to reward the exercise execution and enhance motivation. The exercises change from session to session, and the maximum duration is no longer than 20 minutes. The exercises should only be done 3 times/week; no more than eight exercises each day; and the individual difficulty is regulated by the effort scale to manage the customized progression. In total, 39 different exercises were chosen, and when including their sublevels of progression, a total of 104 different exercises can be completed.

Control Group

Participants in the control group will not receive any specific intervention in addition to the treatment recommended by the health professionals team (doctors, nurses, podiatrists), which includes pharmacological treatment, and self-care recommendations and foot care by international consensus.

Group Type NO_INTERVENTION
