“…The participants practiced the test once, and performed three trials thereafter; with a 60 second break between each trial. The test-retest reliability for the 10MWT-fast is excellent in persons with PD (ICC ≥0.96) [32,33]. The test is valid [32] and can predict fallers among persons with PD [34].…”

BACKGROUND: Parkinson ś disease (PD) is characterized by small, slow movements affecting balance and gait. Lee-Silverman-Voice-Treatment-(LSVT)-BIG is an intensive intervention aiming to restore normal amplitudes of movements. This study aimed to examine whether LSVT-BIG influences dynamic balance and gait in persons with PD. METHODS: We used a Single-Subject-Experimental-Design with three phases; phase A (2 weeks) with no treatment, phase B (4 weeks) with LSVT-BIG-treatment and LSVT-BIG-hometraining, and phase C (7-8 weeks) with LSVT-BIG-home-training. Two persons with PD participated. Outcome measures included the Mini-Balance-Evaluation-Systems-Test (Mini-BESTest) with its four subcomponents ("anticipatory postural adjustments", "postural responses", "sensory orientation", "balance during gait"), the Step-Test (ST) and 10-Meter-Walk-Test-fast (10MWT-fast). The participants were assessed 6, 4 and 8 times during phase A, B and C, respectively. During phase B, they received 16 individual 1-hour LSVT-BIG-treatment sessions and completed between 28 and 39 1-hour sessions LSVT-BIG-home-training. During phase C, they were encouraged to complete one session of home-training every day. RESULTS: The Mini-BESTest-total-score, "balance during gait", ST and 10MWT-fast improved significantly in both participants. One participant demonstrated improved "postural responses". Two of the Mini-BESTest subcomponents were not sensitive to possible improvements. CONCLUSION: LSVT-BIG may have a positive effect on dynamic balance and gait-speed in persons with PD.

“…The 10-meter walk test, a clinic-based assessment of gait speed in PD, has a reported minimal detectable change of 0.22m/s [15], compared to 0.07 m/s with the Emerald device. This increased sensitivity highlights the potential utility of the device in clinical research.…”

“…In order to account for this variability, we evaluated the optimal averaging window duration to capture an inclusive set of gait speed measurements to reflect functional ability, while minimizing monitoring time. We secondarily calculated the minimal detectable change with 95% confidence [15] in mean gait speed over the derived averaging window to evaluate the sensitivity of Emerald to detecting changes in gait speed (online suppl.

Passive Monitoring at Home: A Pilot Study in Parkinson Disease

et al. 2019

We conducted a pilot study using a passive radio-wave-based home monitor in individuals with Parkinson disease (PD) with a focus on gait, home activity, and time in bed. We enrolled 7 ambulatory individuals to have the device installed in the bedroom of their homes over 8 weeks and performed standard PD assessments at baseline. We evaluated the ability of the device to objectively measure gait and time in bed and to generate novel visualizations of home activity. We captured 353 days of monitoring. Mean gait speed (0.39–0.78 m/s), time in bed per day (4.4–12.1 h), and number (1.4–5.9) and duration (15.0–49.8 min) of nightly awakenings varied substantially across and within individuals. Derived gait speed correlated well with the Movement Disorder Society-Unified Parkinson’s Disease Rating Scale total (r = –0.88, p = 0.009) and motor sub-score (r = –0.95, p = 0.001). Six of the seven participants agreed that their activity was typical and indicated a willingness to continue monitoring. This technology provided promising new insights into the home activities of those with PD and may be broadly applicable to other chronic conditions.

“…The change in walking speed from T 0 to T 2 about 0.11 m/s in maximum walking speed out of the 10MWT cannot be interpreted as clinically relevant or might be indicating a measuring error. Lang et al [17] have analyzed in persons suffering from Parkinson's Disease (PD) the Minimal Detectable Change (MDC) for the 10MWT. In the selfchosen walking speed the MDC amounts to 0.22 m/s and in the maximum walking speed to 0.23 m/s.…”

Background: Until now, the etiology of Multiple Sclerosis (MS) has not been clarified. The symptoms vary from person to person and can affect motor, sensory, and cognitive body functions.Objectives: Next to pharmacological treatments, non-pharmacological therapy approaches become more and more important for maintaining physical, sensory, psychological and social functions in people with MS (pwMS). Furthermore, Biofeedback (BF) seems to be an interesting treatment option in order to improve motor functions such as postural stability, walking safety and walking speed in pwMS. Methods:In the present case study, an Electromyography-Biofeedback (EMG-BF) has been examined over 6 weeks in a 74-year old female with MS. Functional Gait Assessment (FGA) and 10-Meter-Walking-Test (10MWT) has been tested pre (t0), after three weeks, (t1) and after six weeks (t2) of treatment (2x/week). Results:The results showed an increase in walking speed after 3 and 6 weeks in 10MWT and a decrease of postural stability after 3 weeks. In contrast, postural stability increased after 6 weeks. The participant tolerated the EMG-BF training very well and she felt more secure in everyday life in relating to a better perception of her feet in the moment of foot contact while walking.Conclusions: EMG-BF training has been examined especially in order to improve the control of pelvic floor muscles in pwMS. Additionally, pwMS might benefit from BF training in regard to improve gait and postural control. More research is necessary to examine BF therapy options in order to support pwMS in their current motor impairments.Citation: Kersten S, Fuchs B, Liebherr M (2017) EMG -Supported Biofeedback Training in a Person with Multiple Sclerosis -A Case Study.
