This study focuses on improving balance control and somatosensory functions in individuals aged 60 years and older with diabetes mellitus tyoe 2 (DMT2). Older adults with DMT2 are at an increased risk of balance problems due to diabetic complications such as neuropathy, retinopathy, and possibly reduced vestibular function. The aim of the study is to investigate whether a 12-week exercise program, with or without additional balance exercises, can improve balance control, enhance somatosensory functions (such as touch and vibration thresholds), and positively impact diabetes-related parameters, including HbA1c levels.
The study is designed as a randomized controlled trial (RCT). Participants are selected based on reduced balance control identified in a prior cross-sectional study. The intervention group follows an exercise program in accordance with international guidelines, supplemented with balance exercises supervised by the researcher (physiotherapist). The control group follows the same guidelines but without balance exercises; instead, they perform relaxation exercises. Balance control is assessed both statically and dynamically, while somatosensory functions are measured, and diabetes-related parameters are collected.
The intervention is primarily home-based, supported by an activity tracker, but the balance or relaxation exercises are conducted under supervision at a designated location. This study aims to contribute to the quality of life of older adults with DMT2 by reducing balance problems and fall risks.
Diabetes mellitus type 2 (DMT2) is the most common form of diabetes, typically occurring after the age of 40. Insulin resistance, reduced insulin secretion, or a combination of both underlie the disease, resulting in elevated blood sugar levels (hyperglycemia). The development of DMT2 is attributed to a lifestyle characterized by reduced physical activity, sedentary behavior, and poor dietary habits, leading to an increased body fat percentage, particularly through the accumulation of visceral adipose tissue. Prolonged fatty acid concentrations and hormonal imbalances result in oxidative stress, which disrupts the environment responsible for the body's sensitivity to insulin. Consequently, insulin resistance develops, and over time, reduced insulin secretion occurs due to the exhaustion of pancreatic β-cells. Risk factors for DMT2 include being overweight, obesity, metabolic disturbances (dyslipidemia, high blood pressure, hyperglycemia), and smoking. It is estimated that 8% of the Belgian population is affected by DMT2, a percentage expected to increase in the future (1). Individuals with DMT2 may develop diabetic complications if blood sugar levels (especially hyperglycemia) remain uncontrolled. At the time of diagnosis, 30% of patients already experience complications (2). After more than 10 years of diagnosis, the risk of damage to large and/or small blood vessels (angiopathy) increases. Common complications include damage to small vessels in the eyes (retinopathy) and diabetic neuropathy, which can impair tactile sensation (perception of touch/pressure) and vibratory sense (perception of vibrations) (3-5).
Physical activity has long been recognized as a key intervention for improving various diabetes-related characteristics in individuals with DMT2, such as insulin sensitivity and glucose control. Studies have shown that both aerobic (endurance) training and strength training contribute to better blood sugar regulation and overall health. These forms of physical activity not only improve muscle mass but also enhance cardiovascular health and endurance, benefiting the overall physical fitness of individuals with DMT2.
Although these general exercise interventions are effective, it remains unclear whether they are sufficient to address specific balance issues in this population. As balance control depends on a complex integration of somatosensory input, muscle strength, and coordination, the question arises whether adding targeted balance exercises to an exercise program is necessary to improve balance control.
This study investigates whether a standard exercise program consisting of aerobic training and strength training, in line with international guidelines, is sufficient to improve balance control in older adults with DMT2, or whether specific balance exercises are necessary. The distinction between the intervention and control groups allows for the evaluation of the relative impact of balance exercises. These findings could contribute to a more targeted and efficient approach to addressing balance problems in this population.

The intervention arm runs for 12 weeks and follows ADA/EASD guidance. Participants complete ≥150 minutes per week of aerobic activity on at least three days, choosing their preferred modality and setting (e.g., walking, treadmill, cycling, swimming, rowing, elliptical, arm ergometer; home, outdoors, gym, or group). Sedentary time should be minimized, and strength training is advised twice weekly with progressive loading. The distinctive component is balance training: 9 supervised sessions of 30 minutes delivered by a research physiotherapist or via home visit if travel is not feasible. Each session includes a warm-up, targeted static and dynamic balance work performed with and without simple equipment such as a foam pillow, and a cooldown with upper- and lower-body stretching. Exercises are progressed and individualized to challenge stability while maintaining safety and feasibility for older adults, with consistent therapis
Behavioral: Balance control and exercise training
Similar to the intervention group, participants in this group will follow recommended physical activity guidelines. Participants can also choose the preferred aerobic and strength physical activity, but excluding yoga, Thai chi or other balance involving exercises. Moreover, this group will not receive any balance exercises as part of their exercise program. To have an equal one-on-one time with the researcher physical therapist, participants will receive relaxation exercises for 30 minutes per week for a total of 9 sessions.

Static balance control
Standing balance is measured with four modified Romberg conditions of increasing difficulty, each performed with eyes open and eyes closed. Each position is held as long as possible up to 30 seconds. Timing starts once a steady stance is achieved and stops at loss of position or at 30 seconds. Three trials are permitted per condition and the best trial counts. Scores from all eight conditions are summed to a total score ranging from 0 to 240 seconds.
Time frame: At baseline and after 12 weeks intervention
Timed Up and Go
Dynamic balance is assessed with the Timed Up and Go test using a standardized protocol, in which participants rise from a chair, walk three metres, turn, return and sit down. The time needed to complete the test is recorded in seconds. The test is performed in three trials and the best performance is retained.
Time frame: At baseline and after 12 weeks intervention
Tandem Gait
Dynamic balance is assessed with a tandem gait test in which participants attempt 20 consecutive heel to toe steps along a straight tape line. The test ends at 20 steps or at violation of the test guidelines. The score is the number of correctly performed steps, ranging from 0 to 20, and is obtained in three trials with the best performance retained.
Time frame: At baseline and after 12 weeks intervention
Mini Balance Evaluation Systems Test
Balance control is assessed with the Mini Balance Evaluation Systems Test, a 14 item performance based test covering anticipatory postural adjustments, reactive postural control, sensory orientation and dynamic gait. Each item is scored from 0 to 2, giving a total score ranging from 0 to 28, with higher scores indicating better balance control.
Time frame: At baseline and after 12 weeks intervention
Touch pressure threshold
Touch pressure thresholds are assessed with Semmes Weinstein monofilaments using the 4-2-1 stepping algorithm. A set of 20 logarithmically ordered filaments is applied and at each step the same filament delivers five stimuli. Testing covers six foot sites across plantar and dorsal regions and the threshold is reported per site as the filament scale value.
Time frame: At baseline and after 12 weeks intervention
Vibration threshold: neurothesiometer
Vibration thresholds are assessed with a Howell neurothesiometer. Vibration at 56 Hz is delivered while the voltage increases from 0 to 50 volts and the participant signals when vibration is first perceived. That voltage is recorded as the vibration detection threshold, with lower values indicating better vibration sense.
Time frame: At baseline and after 12 weeks intervention
Vibration threshold: tuning fork
Vibration sense is assessed with a 128 Hz Rydel Seiffer tuning fork. The fork is struck maximally and placed on standardized reference points until the vibration fades, and the participant signals when it is no longer felt. The result is read from the 0 to 8 scale of the fork, with higher scores indicating better vibration sense.
Time frame: At baseline and after 12 weeks intervention
Self-Reported Physical activity: frequency
Habitual physical activity is assessed with the International Physical Activity Questionnaire Short Form, a self reported questionnaire covering the preceding seven days. Participants report the number of days on which vigorous activity, moderate activity and walking were performed, counting only bouts of at least ten minutes. The frequency is reported separately for each of the three domains and expressed in days per week, with a possible range of 0 to 7 days.
Time frame: At week 1, week 12 of intervention and week 16 (follow-up)
Self-reported physical activity: duration
Habitual physical activity is assessed with the International Physical Activity Questionnaire Short Form, a self reported questionnaire covering the preceding seven days. Participants report the usual duration of vigorous activity, moderate activity and walking on the days these were performed, counting only bouts of at least ten minutes. Durations reported in hours and minutes are converted to minutes and multiplied by the number of days per week, giving the total weekly duration for each of the three domains, expressed in minutes per week and reported separately per domain.
Time frame: At week 1, week 12 of intervention and week 16 (follow-up)
Self-reported physical activity: sedentary time
Sedentary behaviour is assessed with the International Physical Activity Questionnaire Short Form as the time spent sitting on a typical weekday during the preceding seven days, including sitting at work, at home, while studying and during leisure time, and excluding time spent sleeping. Participants report this in hours and minutes, which are converted into a single value expressed in minutes per day.
Time frame: At week 1, week 12 of intervention and week 16 (follow-up)
Daily energy expenditure
Objective physical activity is monitored with the Garmin Vivosmart 5 worn on the wrist continuously throughout the monitoring period and removed only for charging. The device estimates total daily energy expenditure from accelerometry and heart rate data, combining resting and activity related expenditure. Values are averaged across all valid recording days, defined as days with sufficient wear time, to arrive at a single value expressed in kilocalories per day.
Time frame: At week 1, week 12 of intervention and week 16 (follow-up)
Heart rate
The same wrist worn activity tracker records heart rate continuously by optical sensor throughout the monitoring period. Recorded values are averaged across all valid recording days, defined as days with sufficient wear time, to arrive at a single value expressed in beats per minute.
Time frame: At week 1, week 12 of intervention and week 16 (follow-up)
Step count
The Garmin vivosmart 5 activity tracker registers daily step counts that are averaged across all valid recording days, defined as days with sufficient wear time, to arrive at a single value expressed in steps per day
Time frame: At week 1, week 12 of intervention and week 16 (follow-up)
Functioning confidence
Activities-Specific Balance Confidence Scale (ABC scale) describes 16 activities that the participant has to score from 0 to 100%, meaning having no confidence in not losing balance when performing the activity to having maximal confidence. A total score of 1600 can be obtained and will be calculated to a score of 100%, in which a score \<50% indicates low levels of functioning, 50-80% indicates a moderate level of functioning and a score of \>80% means the subject has a high level of functioning.
Time frame: At baseline and after 12 weeks of intervention
Anxiety
Symptoms of anxiety are assessed with the anxiety subscale of the Hospital Anxiety and Depression Scale, a self reported questionnaire covering the preceding week and excluding physical symptoms. The subscale consists of 7 items, each scored from 0 to 3, giving a total score ranging from 0 to 21. Higher scores indicate more symptoms of anxiety.
Time frame: At baseline and after 12 weeks of intervention
Depression
Symptoms of depression are assessed with the depression subscale of the Hospital Anxiety and Depression Scale, a self reported questionnaire covering the preceding week and excluding physical symptoms. The subscale consists of 7 items, each scored from 0 to 3, giving a total score ranging from 0 to 21. Higher scores indicate more symptoms of depression.
Time frame: At baseline and after 12 weeks of intervention
Body Mass Index
Body weight is measured with a digital scale to the nearest 0.1 kilogram and body height is measured with the participant standing against a wall. Both measurements are combined to calculate body mass index as weight divided by height squared, expressed in kilograms per square metre (kg/m\^2).
Time frame: At baseline and after 12 weeks of intervention
Glycated haemoglobin
Glycated haemoglobin is obtained by blood sampling or retrieved from the electronic health record, and reflects average blood glucose concentration over the preceding two to three month, expressed in %.
Time frame: At baseline and after 12 weeks of intervention
